AN - 70729704; 16445757 AB - The putative virulence factor enterohemolysin, encoded by the ehlyA gene, has been closely associated with the pathogenic enterohemorrhagic Escherichia coli (EHEC) group. Escherichia coli isolates from effluents from seven geographically dispersed municipal wastewater treatment plants were screened for the presence of enterohemolysin. A total of 338 E. coli isolates were found to express the ehlyA gene. However, none of the isolates contained the toxin-encoding genes (stxA or stxB) associated with EHEC. Two of the 338 isolates possessed the virulence factor intimin, encoded by the eae gene. These findings suggest that the ehlyA gene may be widely distributed among non-EHEC isolates in the environment.

AN - 70720588; 16433347 AB - Emission rates, decay rates, and cooking durations are reported from continuous PM2.5 (particulate matter less than 2.5 microm) concentrations measured using personal DataRam nephelometers (1-min time resolution) from the Research Triangle Park (RTP) PM panel study. The study (n = 37 participants) included monitoring for 7 consecutive days in each of four consecutive seasons (summer 2000 through spring 2001). Cooking episodes (n = 411) were selected using time-activity diaries and criteria for cooking event duration, peak concentration level, and decay curve quality. Averaged across all cooking events, mean source strengths were 36 mg/min (median = 12 mg/min), mean decay rates were 0.27 h(-1) (0.17 h(-1)), and mean cooking durations were 11 min (7 min). Cooking events were further separated into one of seven categories representing cooking method: burned food (oven cooking, toaster, or stovetop cooking), grilling, microwave, toaster oven, frying, oven cooking, and stovetop cooking. The highest mean source strengths were identified from burned food (mean = 470 mg/min), grilling (173 mg/min), and frying (60 mg/ min); differences between both burned food and grilling compared with all remaining cooking methods were statistically significant. Source strengths, decay rates, and cooking durations were also compared by season and typical meal times (8:00 a.m., 12:00 p.m., and 6:00 p.m.); differences were generally not statistically significant for these cases. Mean source strengths using electric appliances were typically a factor of 2 greater than those using gas appliances for identical cooking methods (frying, oven cooking, or stovetop cooking), although in all cases the difference was not statistically significant. Distributions of source strengths and decay rates for cooking events were also compared among study subjects to assess both within- and between-subject variability. Each subject's distribution of source strengths during the study tended to be either lower than the overall study average (and with lower variability) or higher than the overall study average (and with higher variability). No relationships could be found between source strength and either subject characteristics (age, gender, employment status) or home characteristic (daily air exchange rate). The large number of cooking events and the broad range of cooking activities included in this analysis makes the reported distributions of PM2.5 source strengths useful for probabilistic exposure modeling even though the study population was limited.

AN - 70703957; 16433362 AB - The United States Environmental Protection Agency's Office of Ground Water and Drinking Water has developed a single-laboratory quantitation procedure: the lowest concentration minimum reporting level (LCMRL). The LCMRL is the lowest true concentration for which future recovery is predicted to fall, with high confidence (99%), between 50% and 150%. The procedure takes into account precision and accuracy. Multiple concentration replicates are processed through the entire analytical method and the data are plotted as measured sample concentration (y-axis) versus true concentration (x-axis). If the data support an assumption of constant variance over the concentration range, an ordinary least-squares regression line is drawn; otherwise, a variance-weighted least-squares regression is used. Prediction interval lines of 99% confidence are drawn about the regression. At the points where the prediction interval lines intersect with data quality objective lines of 50% and 150% recovery, lines are dropped to the x-axis. The higher of the two values is the LCMRL. The LCMRL procedure is flexible because the data quality objectives (50-150%) and the prediction interval confidence (99%) can be varied to suit program needs. The LCMRL determination is performed during method development only. A simpler procedure for verification of data quality objectives at a given minimum reporting level (MRL) is also presented. The verification procedure requires a single set of seven samples taken through the entire method procedure. If the calculated prediction interval is contained within data quality recovery limits (50-150%), the laboratory performance at the MRL is verified.

AN - 70680251; 16405462 AB - Since 1999, Ohio EPA hydrogeologists have used two analytic element models (AEMs), the proprietary software GFLOW and U.S. EPA's WhAEM, to delineate protection areas for 535 public water systems. Both models now use the GFLOW2001 solution engine, integrate well with Geographic Information System (GIS) technology, have a user-friendly graphical interface, are capable of simulating a variety of complex hydrogeologic settings, and do not rely upon a model grid. These features simplify the modeling process and enable AEMs to bridge the gap between existing simplistic delineation methods and more complex numerical models. Ohio EPA hydrogeologists demonstrated that WhAEM2000 and GFLOW2000 were capable of producing capture zones similar to more widely accepted models by applying the AEMs to eight sites that had been previously delineated using other methods. After the Ohio EPA delineated protection areas using AEMs, more simplistic delineation methods used by other states (volumetric equation and arbitrary fixed radii) were applied to the same water systems to compare the differences between various methods. GIS software and two-tailed paired t-tests were used to quantify the differences in protection areas and analyze the data. The results of this analysis demonstrate that AEMs typically produce significantly different protection areas than the most simplistic delineation methods, in terms of total area and shape. If the volumetric equation had been used instead of AEMs, Ohio would not have protected 265 km2 of critical upgradient area and would have overprotected 269 km2 of primarily downgradient land. Since an increasing number of land-use restrictions are being tied to drinking water protection areas, this analysis has broad policy implications.

AN - 70194670; 16081193 AB - In this study, we present approximately two years (January 1999-December 2000) of atmospheric NH3, NH4+, HCl, Cl-, HNO3, NO3-, SO2, and SO4= concentrations measured by the annular denuder/filter pack method at an agricultural site in eastern North Carolina. This site is influenced by high NH3 emissions from animal production and fertilizer use in the surrounding area and neighboring counties. The two-year mean NH3 concentration is 5.6 (+/-5.13) microg m(-3). The mean concentration of total inorganic PM2.5, which includes SO4=, NO3-, NH4+, and Cl-, is 8.0 (+/-5.84) microg m(-3). SO4=, NO3-, NH4+, and Cl- represent, respectively, 53, 24, 22, and 1% of measured inorganic PM2.5. NH3 contributes 72% of total NH3 + NH4+, on an average.

AN - 68202119; 17135144 AB - The California Pesticide Illness Surveillance Program (PISP) is a major resource for pesticide illness epidemiology. This work attempts to improve characterization of pesticide illness in California, evaluate case ascertainment of the PISP and identify PISP's limitations and biases for studying the incidence and epidemiology of pesticide-related illness. Abstractors collected standardized information from 1994-1996 PISP files, poison control logs, hospital records, and death certificates. Linkage produced a merged file of all records that documented consideration of pesticide exposure as a cause of ill health. We identified 23 deaths and estimated 1,310 hospitalizations attributable to pesticide exposure, corresponding to 0.024 fatalities and 1.38 hospitalizations (95% confidence interval [CI] = 1.01-1.74) per 100,000 California population person-years. Most intoxications followed domestic exposures and were not reported to the surveillance program, which identified primarily occupational exposures. Excluding groups of five or more, we estimated 16% ascertainment (CI = 0.05-0.27) for non-agricultural occupational cases. Agricultural connections increased the probability of ascertainment to about 50%, cultural and economic barriers notwithstanding. Surveillance records existed for all identified episodes in which five or more people were exposed. California pesticide surveillance data appear complete for mass exposures, and adequate to characterize agricultural and occupational exposures. Work is needed to explore domestic exposures and occurrences beyond the reach of the health care system.

The goal is to ensure that studies are scientifically appropriate and necessary without being redundant, and that tests emphasize toxicological endpoints and exposure durations that are relevant for risk assessment. The ACSA Life Stages Task Force proposes a tiered approach to toxicity testing that assesses a compound's potential to cause adverse effects on reproduction, and that assesses the nature and severity of effects during development and adolescence, with consideration of the sensitivity of the elderly. While incorporating many features from current guideline studies, the proposed approach includes a novel rat reproduction and developmental study with enhanced endpoints and a rabbit development study. All available data, including toxicokinetics, ADME data, and systemic toxicity information, are considered in the design and interpretation of studies. Compared to existing testing strategies, the proposed approach uses fewer animals, provides information on the young animal, and includes an estimation of human exposure potential for making decisions about the extent of testing required.

AN - 67949074; 16682506 AB - Characterizing gene expression in hair follicles can help to elucidate the hair growth cycle by delineating the genes and pathways involved in follicular growth and degeneration. The objectives of this study were to determine whether intact RNA could be extracted from a small number of plucked, unstaged hair follicles in sufficient quantity to conduct gene expression profiling, and to conduct global gene expression profiling. To this end, RNA was extracted from 1 to 3 unstaged follicles plucked from the scalp of 36 volunteers. The average quantifiable yield of RNA/follicle was 112.5 ng. Ribosomal ratios were lower than normally expected, but investigation indicated the RNA was intact. Ten of the samples were amplified and hybridized to Affymetrix genechips. On average, 2,567 of the total probe sets (8,500) were expressed in each sample; 1,422 were expressed in all 10 samples; 97 were significantly changed in one gender compared to the other, and 41 had high levels of interindividual variability. This study demonstrates that RNA of sufficient quantity and quality to use in microarray hybridizations can be obtained from as little as a single plucked human hair follicle. Genes expressed in all individuals are probably related to follicular growth and could form a starting set for developing signatures of toxicant exposure. The differentially expressed genes could be involved in producing gender and interindividual differences in hair growth.

AN - 67907859; 16640321 AB - As contaminated sediment sites in freshwater and marine environments come under increasing scrutiny, and the importance of these sites with regard to ecological and human health is better understood, the number of contaminated sediment sites requiring risk characterization and management is increasing. Risk reduction must be the long-term goal of all sediment management practices. Risk management strategies in aquatic environments focus on mitigating potential exposure pathways for contaminants that may pose an ecological or human health risk over time. Sediment management practices include dredging ("environmental dredging"), capping, monitored natural recovery, and combinations of these generic response actions. A Remedy Effectiveness Panel was selected to identify and discuss the key issues associated with the performance of these generic response actions for contaminated sediments. The panel convened in New Orleans on 26 January 2005 at Battelle's Third International Conference on the Remediation of Contaminated Sediments and made 3 presentations on response actions to conference attendees followed by an open dialog between attendees and panel members. This article introduces the 3 generic response actions, identifies key topics from the open dialog and presents opinions expressed, and provides a summary and observations.

AN - 67709788; 16498636 AB - We utilized radioactive 73As-labeled arsenite and vacuum filtration methodology to determine the binding affinity of arsenite to eight synthetic peptides ranging from 13 to 24 amino acids long and containing one or two cysteines separated by 0-17 intervening amino acids. Six of the eight peptides were highly similar in amino acid sequence and were based on cysteine containing regions of the hormone-binding site of the human estrogen receptor-alpha (e.g., the sequence of peptide 28 is LEGAWCGKGVEGTEHLYSMKCKNV). The peptides with 0-14 intervening amino acids between two cysteines bound arsenite with Kd values of 2.7-20.1 uM and with Bmax values from 36 to 103 nmol/mg protein (from 0.083 to 0.19 nmol/nmol of protein). Thus, increasing the number of intervening amino acids from 0 to 14 made very little difference in the observed Kd values for arsenite, a surprising finding. Therefore, these peptides are flexible in solution and effectively contain a dithiol high affinity binding site for arsenite. Peptide 17 with two C separated by 19 amino acids bound arsenite with a Kd of 123 uM and a Bmax of 41.8 nmol/mg. The monothiol peptide 19 bound arsenite with a Kd of 124 uM and a Bmax of 26 nmol/mg protein. All experimental binding curves fit well to a one site binding model. 2006 Wiley Periodicals, Inc.

AN - 67709071; 16512249 AB - U.S. Environmental Protection Agency (EPA) Method 535 has been developed in order to provide a method for the analysis of "Alachlor ESA and other acetanilide degradation products," which are listed on EPA's 1998 Drinking Water Contaminant Candidate List. Method 535 uses solid-phase extraction with a nonporous graphitized carbon sorbent to extract the ethane sulfonic acid (ESA) and oxanilic acid degradates of propachlor, flufenacet, dimethenamid, alachlor, acetochlor, and metolachlor from finished drinking water matrixes. Separation and quantitation of the target analytes are achieved with liquid chromatography/tandem mass spectrometry. Dimethachlor ESA and butachlor ESA were chosen during the method development as the surrogate and internal standard.

AN - 67706803; 16498640 AB - We determined the number and the dissociation rate constants of different complexes formed from arsenite and two peptides containing either one (RVCAVGNDYASGYHYGV for peptide 20) or three cysteines (LECAWQGK CVEGTEHLYSMKCK for peptide 10) via radioactive 73As-labeled arsenite and vacuum filtration methodology. Nonlinear regression analysis of the dissociation of both arsenite-peptide complexes showed that triphasic fits gave excellent r2 values (0.9859 for peptide 20 and 0.9890 for peptide 10). The first phase of arsenite-peptide dissociation had the largest span (decrease in binding), and the rate was too fast to be measured using vacuum filtration methods. The dissociation rate constants of arsenite-peptide complexes for the second phase were 0.35 and 0.54 min(-1) and for the third phase were 0.0071 and 0.0045 min(-1) for peptides 20 and 10, respectively. For peptide 20, the three spans of triphasic decay were 85%, 9%, and 7% of the total binding of 16.1 nmol/mg protein. For peptide 10, which can bind in both an intermolecular and intramolecular manner, the three spans of triphasic decay were 59%, 16%, and 25% of the total binding of 43.7 nmol/mg protein. Binding of trivalent arsenicals to peptides and proteins can alter their structure and function and contribute to adverse health outcomes such as toxicity and carcinogenicity. 2006 Wiley Periodicals, Inc.

AN - 67607302; 16393903 AB - Determination of acaricide residues of flumethrin, tau-fluvalinate, coumaphos, and amitraz in honey and beeswax was carried out using a rapid extraction method utilizing C-18 SPE cartridges and an analytical method utilizing GC with ECD, NPD, and MSD detectors for the four acaricides. Recovery percentages from the extraction method ranged from 90-102%, while the minimum detection levels ranged from 0.01-0.05 mg/kg for the acaricides. Nine of the 21 analyzed samples were found to be contaminated with the acaricides tau-fluvalinate and coumaphos. Neither flumethrin nor amitraz was detected in any of the honey or wax samples. Coumaphos was found only in honey samples in which two samples exceeded the tolerance levels set by EPA and EC regulations. It has not been detected in beeswax. Five honey samples and eight beeswax samples were found to be contaminated with tau-fluvalinate. One of the wax samples was contaminated with a relatively high residue of tau-fluvalinate and contained above 10 mg/kg. JF - Journal of environmental science and health. Part.

AN - 67606846; 16393867 AB - It is well established that human diseases associated with abnormal immune function, including some common infectious diseases and asthma, are considerably more prevalent at younger ages. Although not established absolutely, it is generally believed that development constitutes a period of increased immune system susceptibility to xenobiotics, since adverse effects may occur at lower doses and/or immunomodulation may be more persistent, thus increasing the relative risk of xenobiotic exposure to the immunologically immature organism. To address this issue, a brief overview of immune maturation in humans is provided to demonstrate that functional immaturity alone predisposes the young to infection. Age-dependent differences in the immunotoxic effects of five diverse compounds, diethylstilbestrol (DES), diazepam (DZP), lead (Pb), 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), and tributyltin oxide (TBTO), which have undergone adult and developmental immunotoxicity testing in rodents, are then reviewed, as are human data when available. For all five chemicals, the developing immune system was found to be at greater risk than that of the adult, either because lower doses produced immunotoxicity, adverse effects were more persistent, or both.

In karstic terranes, leakage from losing and sinking streams typically resurge at downstream springs, but flow may be intercepted by production wells. Although sinking streams that disappear into swallow holes and caves are relatively easy to trace, developing a tracer test design for a losing stream that allows slow percolation through its bed is complicated by the lack of basic knowledge regarding leakage rate, leakage locations along its length, and temporal variability. To overcome these complications, modification to the Efficient Hydrologic Tracer-test Design (EHTD) program were undertaken. Simultaneous use of both pumping wells and springs as sampling stations constituted initial modifications to EHTD. Additional modifications were then taken to address the problem of losing streams by using the total volume of flow leaking through the bed of a losing stream as determined by taking the difference between upgradient and downgradient discharge measurements or as estimated from the effective porosity of the stream bed. Leakage rate may be set if measured or may be taken as a function of the estimated mean travel time for the losing stream. These modifications are also effective for dry stream channel in which an artificial flow is necessarily added to facilitate a tracer test.

Inorganic contaminants were detected in many of the wells, and concentrations exceeded the U.S. EPA maximum contaminant levels (MCLs; federal drinking water standards used to regulate public drinking water quality) more often than organic contaminants. Of the inorganic constituents evaluated, arsenic concentrations exceeded the MCL (10 mu g/L) in approximately 11% of the 7580 wells evaluated, nitrate exceeded the MCL (10 mg/L) in approximately 8% of the 3465 wells evaluated, uranium-238 exceeded the MCL (30 mu g/L) in approximately 4% of the wells, and radon-222 exceeded 300 and 4000 pCi/L (potential drinking water standards currently under review by the U.S. EPA) in approximately 75% and 9% of the wells, respectively. The MCLs for total mercury and fluoride were each exceeded in <1% of the wells evaluated. The MCL was exceeded in <1% of all wells for all anthropogenically derived organic contaminants evaluated and was not exceeded for many contaminants. In addition, 10 contaminants evaluated do not currently have an MCL. Atrazine, however, was detected in 24% of the wells evaluated and was the most frequently detected organic contaminant of the 28 organic contaminants evaluated in this study. Simazine and metolachlor each were detected in approximately 9% of all wells and tied for second in frequency of detection for organic contaminants. The third and fourth most frequently detected organic contaminants were methyl tert-butyl ether (MTBE) (6%) and chloroform (5%), respectively. Because the water quality of domestic wells is not federally regulated or nationally monitored, this study provides a unique, previously nonexistent, perspective on the quality of the self-supplied drinking water resources used by approximately 45 million Americans in the United States.

In this pilot study, saliva was collected from 20 healthy adults once per week for 5 consecutive weeks using 2 different collection methods: a disposable plastic pipette, and a cotton-wool roll. A brief questionnaire was conducted each week to document changes in exposure to cholinesterase inhibitors for the duration of the sampling. To measure cholinesterase activity, an existing radiometric method was modified to make it suitable for human saliva. Using this method, cholinesterase activity was measurable in saliva, and duplicate samples showed reliable repeatability. Activity in both collection methods ranged from 3 to 265 nmol/h/ml saliva (mean = 52 plus or minus 37 [SD] nmol/h/ml saliva). For some individuals, enzyme activity was consistent over the five sampling weeks; for others, activity was highly variable. Coefficients of variation (CVs) were calculated to assess variability, and mean CVs were the same for both collection methods (about 35%). Adjusting for protein concentration in the pipette-collected samples did not change results. Both collection methods worked well for collecting between 1 and 3 ml saliva, but at the majority of visits (86%), participants preferred the cotton-wool roll. Results from this study suggest that saliva may be a useful indicator of potential neurotoxic effects from exposure to organophosphorus and carbamate pesticides, but that factors affecting variability should be explored further.

Arsenic was primarily associated with ferrihydrite (60-70%), with the remainder found in arsenopyrite (30-40%). Lead was observed almost exclusively as anglesite (PbSO sub(4)), with <1% observed as galena (PbS). The identification of As in oxidized Fe oxides and Pb as PbSO sub(4) is in disagreement with the dominant reduced phases previously reported and suggests As and Pb contained within the mine waste-derived product are more bioavailable than previously considered. Aging studies in solution result in Ironite granules separating into two distinct fractions, an orange oxide precipitate and a crystalline fraction with a metallic luster. The orange oxide fraction contained As adsorbed/precipitated with ferrihydrite that is released into solution when allowed to equilibrate with water. The fraction with a metallic luster contained pyrite and arsenopyrite. A complete breakdown of arsenopyrite was observed in Ironite aged for 1 month in buffered deionized water. The observations from this study indicate As and Pb exist as oxidized phases that likely develop from the beneficiation and processing of mine tailings for commercial sale. The potential release of As and Pb has important implications for water quality standards and human health. Of particular concern is the quantity of As released from mine waste-derived products due to the new As regulation applied in 2006, limiting As levels to 10 mg L super(- ) super(1) in drinking water.

Under laboratory conditions, environmentally relevant levels of many air pollutants enhance susceptibility to bacterial pneumonia in mice. Because these compounds do not necessarily affect systemic immune responses, conventional testing for immune suppression does not adequately predict this risk. The underlying mechanism is suppression of alveolar macrophage (AM) phagocytic activity that ordinarily clears these organisms from the lung. Hence, the most practical way to test for this risk is to assess AM function in bronchoalveolar lavage fluid. Methods for assessing chemicals for the potential to cause allergic asthma are not as clear-cut Low-molecular-weight chemicals are not physically large enough to initiate an immune response on their own; to produce sensitization they must be reactive enough to complex with protein. Structure-activity approaches and testing in vitro for reactivity with protein have been proposed for use in hazard identification. Diisocyanates and acid anhydrides are structures associated with occupational asthma. These types of chemical allergen appear to be a subset of chemicals that test positive in contact sensitivity assays, such as the local lymph node assay (UNA). It has been proposed that "asthmagens" can be further distinguished from other types of sensitizers by the potential to induce T helper 2-mediated responses. Several approaches have been proposed but none have been widely accepted.

Abnormal weather conditions might lead to higher or lower ambient air concentrations than they would be under normal weather conditions. Therefore, testing for normality of weather conditions during the air monitoring period is an essential step for evaluating ambient air monitoring results. In this paper, a distance method was used to select a most representative weather station from the available candidates. An array of meteorological elements were identified that affect air dispersion and transportation. A statistical method was used to determine whether the weather conditions during the air monitoring period were significantly different from that of previous years. Using methyl bromide ambient air monitoring as a case study, this paper documents the methods, procedures, and results of weather analysis for Monterey, Santa Cruz, and Kern Counties during ambient air monitoring periods for methyl bromide in the year 2000. With a few exceptions, the meteorological elements and atmospheric stability factors, such as wind speeds, wind directions, and stability classes, during the monitoring period were in the normal range. Although there were higher frequencies of stable atmospheric conditions in Monterey/Santa Cruz Counties than in Kern County, weather conditions during the monitoring period were not significantly different from normal local weather conditions of previous years. Consequently, the subchronic air concentrations observed during the ambient air monitoring periods for methyl bromide in the year 2000 was taken under typical weather conditions of those areas at that time of the year.

The present study was focused on understanding the primary mechanism responsible for the suppressant effect of SO sub(2) on total PCDD/F formation and toxic equivalent (TEQ) emissions. The addition of SO sub(2), simulating the effect of coal addition on the flue gas composition, resulted in significant reductions in the TEQ emissions due to reactions involving SO sub(2) in the postcombustion zone. However, emissions of total PCDDs/Fs, unlike the TEQ value, were dependent upon the Cl sub(2) and SO sub(2) injection temperatures due to increases in non-TEQ correlated isomers. The conversion of metal chlorides in the fly ash to sulfates, thus reducing the sites responsible for chlorination/oxidation reactions, was concluded to be the main suppressant mechanism; proposed reactions for copper and iron are presented. This mechanism was found to be independent of combustion conditions and could have prolonged effects on PCDD/F emissions from deposits formed with high flue gas S/Cl ratios.

Sugarcane leaves from Hawaii and Florida were burned in a manner simulating the natural physical dimensions and biomass density found during the practice of preharvest field burning. Eight composite burn tests consisting of 3-33 kg of biomass were conducted, some with replicate samplers. Emission factor calculations using sampled concentration and measured mass loss compared well to rigorous carbon balance methods commonly used in field sampling. The two sources of sugarcane had distinctive emission levels, as did tests on separate seasonal gatherings of the Florida sugarcane. The average emission factor for two tests of Hawaii sugarcane was 253 ng toxic equivalents (TEQ)/kg of carbon burned (ng TEQ/kg sub(Cb)) (rsd = 16%) and for two gatherings of Florida sugarcane was 25 ng TEQ/kg sub(Cb) (N = 4, rsd = 50%) and 5 ng TEQ/kg sub(Cb) (N = 2, rsd = 91%). The Hawaii sugarcane, as well as most of the Florida sugarcane, had emission values which were well above the value of 5 ng TEQ/kg sub(Cb) commonly attributed to biomass combustion. Application of this emission factor range to the amount of U.S. sugarcane fields burned suggests that this practice may be a relatively minor source of PCDDs and PCDFs in the U.S. national inventory, but the limited sample size and range of results make this conclusion tenuous.

Gas samples are collected at 20 m, 40 m, and >50 m interval depths within the unconfined aquifers. Gas extraction for super(85)Kr from wells is obtained directly via a wellhead methodology avoiding conventional collection of large sample volumes. Atmospheric super(85)Kr input to the recharge environment is estimated at 1.27 Bq m super(-3) by time-series analyses of weighted monthly precipitation (2001-2004). Numerical simulation of Kr gas transport through the variable unsaturated zones to the water table suggests up to 12-year time lags locally, thus biasing the super(85)Kr groundwater ages. Apparent super(85)Kr ages suggest that similar to -70% of groundwater near 20 m depth was recharged less than 30 years BP (2004). Mass-age transport modeling suggests that post mid-1950s recharge penetrates to part of the basin's floor and that older groundwater seeps from the underlying fractured bedrock may occur.

Tree invasion of grasslands over the last 50 years has had substantial facilitative or antagonistic net impacts on populations of many plant species. Increases in species frequency, indicating net facilitation, generally appear to occur earlier in forest development than do decreases in frequency, indicative of net antagonism. Although more than 20% of the flora showed substantial association with either grassland or forest, the dominant ground-stratum species in each habitat were quite similar and very few grassland species were not recorded in grassy forests. Forb species composition appears to change more rapidly after tree invasion than grass species composition. Relatively few forbs preferred forest to grassland, whereas shrubs, trees or lianes were substantially more frequent in forests. Replacement of grasslands by grassy forests would reduce landscape diversity and impact on other values in the Bunya Mountains. However, this study suggests that most, if not all, vascular plants that currently occur on the grasslands will persist in the area provided the grassy character of the eucalypt forests is maintained.

There were distinct increases in nutrient concentrations in the water and in atmospheric N deposition along the gradient from Lake Superior to Lake Ontario, but few differences between lakes in sediment carbon (C), nitrogen (N) or phosphorus (P). Wetland water and sediment chemistry were correlated with the agricultural stress gradient, hydrological turnover time and atmospheric deposition. The N : P ratio of wetland waters and sediments indicated that these coastal wetlands were N-limited. Nutrient stoichiometry was correlated with the agricultural stress gradient, hydrological turnover time and atmospheric deposition. Extracellular enzyme activity was correlated with wetland sediment and water chemistry and stoichiometry, atmospheric N deposition, the agricultural stress gradient and the hydrological turnover time. The ratios of glycosidases to peptidases and phosphatases yielded estimates of nutrient limitation that agreed with those based solely on nutrient chemistry. This study, the first to link microbial enzyme activities to regional-scale anthropogenic stressors, suggests that quantities and ratios of microbial enzymes are directly related to the concentrations and ratios of limiting nutrients, and may be sensitive indicators of nutrient dynamics in wetland ecosystems, but further work is needed to elucidate these relationships.

However, locating and contacting individuals based on these data sources to collect additional data can be a challenge. METHODS A large case-control study of air quality and birth defects was conducted in 7 Texas counties in which cases were selected from the Texas Birth Defects Registry and controls from state vital records. In 2004, data from these sources were used to trace mothers of cases and controls who delivered babies in the year 2000 (n = 2477) for participation in a computer-assisted telephone interview. A number of factors that predicted whether an individual would be located and interviewed were identified. RESULTS Between March and August 2004, 38% of the mothers were located, and 38% of the located mothers were interviewed. Case mothers were more likely than control mothers to be located (44 vs. 30%) and, if located, to be interviewed (43 vs. 31%). We compared the characteristics of mothers who were not located (case n = 760; control n = 777), mothers who were located but not interviewed (case n = 344; control n = 236), and mothers who were interviewed (case n = 256; control n = 104). Among both cases and controls, older mothers (30 years) were more likely than younger mothers to be located, and non-Hispanic black mothers were least likely to be located and interviewed. CONCLUSIONS Despite the utility of vital records as a source of population-based controls in record-linkage analyses, the poor response rate discourages the use of these data sources to contact individuals for a follow-up study 4 years after delivery.

The principle predicts the selective persistence of ecosystem designs that capture a previously untapped energy source. This hypothesis was investigated empirically in controlled and replicated tests conducted in planktonic microcosms. Microecosystems that developed under a pH-controlled light regime, in which light duration was altered based on changes in an ecosystem-controllable variable (water column pH), were compared with those that developed under fixed photoperiods. According to the principle, pH-decreasing (and power-increasing) organization should selectively persist under pH-controlled light. To assess changes in pH dynamics that occurred under the alternative selection regime, in which photoperiods were not linked with pH-affecting selection or organization, the microecosystems that developed under fixed photoperiods were subjected to pH-controlled light on the last day of each test. The daily light duration increased 506 min on average in microecosystems that developed under pH- controlled light and 412 min on average in microecosystems that developed under fixed photoperiods. Selective reinforcement of acid-secreting blue-green algae in response to CO sub(2) and nutrient limitations could account for the greater increase in power acquisition in microecosystems that developed under pH- controlled light.

Despite a strong association with active maternal smoking and sudden infant death syndrome (SIDS), information on the risk of SIDS due to prenatal and postnatal ETS exposure is relatively inconsistent. This literature review begins with a discussion and critique of existing epidemiologic data pertaining to ETS and SIDS. It then explores the biologic plausibility of this association, with comparison of the known association between active maternal smoking and SIDS, by examining metabolic and placental transfer issues associated with nicotine, and the biologic responses and mechanisms that may follow exposure to nicotine. Evidence indicates that prenatal and postnatal exposures to nicotine do occur from ETS exposure, but that the level of exposure is often substantially less than levels induced by active maternal smoking. Nicotine also has the capacity to concentrate in the fetus, regardless of exposure source. Experimental animal studies show that various doses of nicotine are capable of affecting a neonate's response to hypoxic conditions, a process thought to be related to SIDS outcomes. Mechanisms contributing to deficient hypoxia response include the ability of nicotine to act as a cholinergic stimulant through nicotinic acetylcholine receptor (nAChR) binding. The need for future research to investigate nicotine exposure and effects from non-maternal tobacco smoke sources in mid to late gestation is emphasized, along with a need to discourage smoking around both pregnant women and infants.

The immune system continues to mature after birth, and functional immaturity accounts for much of the increased susceptibility in the young. Although not established absolutely, it is generally believed that development constitutes a period of increased immune system susceptibility to xenobiotics, since adverse effects may occur at lower doses and/or immunomodula-tion may be more persistent, thus increasing the relative risk of xenobiotic exposure to the immunologically immature organism.

Trials were performed at 30 degree C using two coagulant combinations (aluminum sulfate and cationic polymer or ferric chloride and cationic polymer), two initial filter loading rates (7 or 10 m/h) and two species of morphologically different cyanobacteria (Microcystis aeruginosa or Anabaena flos aquae). The filter was perturbed by instantaneously increasing the hydraulic loading rate by 50%. Filter influent and effluent water qualities were characterized by measuring turbidity, particles and chlorophyll a. The observed post-perturbation filter effluent chlorophyll a peaks were 1.6-48 times greater than the pre-perturbation averages. Chlorophyll a peaks were larger for M. aeruginosa than for A. flos aquae. Chlorophyll a peaks were also larger for the higher (10 m/h) than for the lower (7 m/h) initial filter loading rate. The post-perturbation effluent turbidity peaks were 1.4-7.2 times greater than the pre-perturbation averages. The post-perturbation effluent particle peaks were 6.5-25 times greater than the pre-perturbation averages. These results indicate that particles were a more sensitive indicator of cyanobacterial passage than turbidity.

However, little is understood about the exposures to household pesticides and the resultant health effects. One reason that little is known about home-use pesticide exposure is the lack of comprehensive data on exposures to pesticides in the home. One method to help ascertain the amount of pesticides present in the home is use of point-of-sale data collected from marketing companies that track product sales to obtain the volume of pesticides sold for home-use. This provides a measure of volume of home-use pesticide. Methods We have constructed a searchable database containing sales data for home-use permethrin-containing pesticides sold by retail stores in the United States from January 1997 through December 2002 in an attempt to develop a tracking method for pesticide. This pilot project was conducted to determine if point-of-sale data would be effective in helping track the purchase of home-use permethrin containing pesticides and if it would stand as a good model for tracking sales of other home-use pesticides. Results There are several limitations associated with this tracking method, including the availability of sales data, market coverage, and geographic resolution. As a result, a fraction of sales data potentially available for reporting is represented in this database. However, the database is sensitive to the number and type of merchants reporting permethrin sales. Further, analysis of the sale of individual products included in the database indicates that year to year variability has a greater impact on reported permethrin sales than the amount sold by each type of merchant. Conclusion We conclude that, while nothing could completely replace a detailed exposure assessment to estimate exposures to home-use pesticides, a point-of-sale database is a useful tool in tracking the purchase of these types of pesticides to 1) detect anomalous trends in regional and seasonal pesticide sales warranting further investigation into the potential causes of the trends; 2) determine the most commonly purchased application types; and 3) compare relative trends in sales between indoor and outdoor use products as well as compare trends in sales between different active ingredients.

Methods to measure recreational water quality in less than or equal to 2 hr have been developed. Application of rapid methods could give considerably more accurate and timely assessments of recreational water quality. We conducted a prospective study of beachgoers at two Great Lakes beaches to examine the association between recreational water quality, obtained using rapid methods, and gastrointestinal (GI) illness after swimming. Beachgoers were asked about swimming and other beach activities and 10-12 days later were asked about the occurrence of GI symptoms. We tested water samples for Enterococcus and Bacteroides species using the quantitative polymerase chain reaction (PCR) method. We observed significant trends between increased GI illness and Enterococcus at the Lake Michigan beach and a positive trend for Enterococcus at the Lake Erie beach. The association remained significant for Enterococcus when the two beaches were combined. We observed a positive trend for Bacteroides at the Lake Erie beach, but no trend was observed at the Lake Michigan beach. Enterococcus samples collected at 0800 hr were predictive of GI illness that day. The association between Enterococcus and illness strengthened as time spent swimming in the water increased. This is the first study to show that water quality measured by rapid methods can predict swimming-associated health effects.

The Clean Water Act (USC 1972) requires identification of impaired water bodies and determination of the causes of impairment. Classification simplifies these determinations, because estuaries within a class are more likely to respond similarly to particular stressors. We reviewed existing classification systems for their applicability to grouping coastal marine and Great Lakes water bodies based on their responses to aquatic stressors, including nutrients, toxic substances, suspended sediments, habitat alteration, and combinations of stressors. Classification research historically addressed terrestrial and freshwater habitats rather than coastal habitats. Few efforts focused on stressor response, although many well-researched classification frameworks provide information pertinent to stressor response. Early coastal classifications relied on physical and hydrological properties, including geomorphology, general circulation patterns, and salinity. More recent classifications sort ecosystems into a few broad types and may integrate physical and biological factors. Among current efforts are those designed for conservation of sensitive habitats based on ecological processes that support patterns of biological diversity. Physical factors, including freshwater inflow, residence time, and flushing rates, affect sensitivity to stressors. Biological factors, such as primary production, grazing rates, and mineral cycling, also need to be considered in classification. We evaluate each existing classification system with respect to objectives, defining factors, extent of spatial and temporal applicability, existing sources of data, and relevance to aquatic stressors. We also consider classification methods in a generic sense and discuss their strengths and weaknesses for our purposes. Although few existing classifications are based on responses to stressors, many well- researched paradigms provide important information for improving our capabilities for classification as an investigative and predictive management tool.

Crime is an important element of the neighborhood environment inadequately investigated in the reproductive and public health literature. When crime has been used in research, it has been variably defined, resulting in non-comparable associations across studies. Methods Using geocoded linked birth record, crime and census data in multilevel models, this paper explored the relevance of four spatial violent crime exposures: two proximal violent crime categorizations (count of violent crime within a one-half mile radius of maternal residence and distance from maternal residence to nearest violent crime) and two area-level crime categorizations (count of violent crimes within a block group and block group rate of violent crimes) for adverse birth events among women in living in the city of Raleigh NC crime report area in 1999-2001. Models were adjusted for maternal age and education and area-level deprivation. Results In black and white non-Hispanic race-stratified models, crime characterized as a proximal exposure was not able to distinguish between women experiencing adverse and women experiencing normal birth outcomes. Violent crime characterized as a neighborhood attribute was positively associated with preterm birth and low birth weight among non-Hispanic white and black women. No statistically significant interaction between area-deprivation and violent crime category was observed. Conclusion Crime is variably categorized in the literature, with little rationale provided for crime type or categorization employed. This research represents the first time multiple crime categorizations have been directly compared in association with health outcomes. Finding an effect of area-level violent crime suggests crime may best be characterized as a neighborhood attribute with important implication for adverse birth outcomes.

One component of that effort was an examination of the possible transport of radioactivity from sludge into the local environment and the subsequent exposure of humans. A stochastic environmental pathway model was applied separately to seven hypothetical, generic sludge-release scenarios, leading to the creation of seven tables of Dose-to-Source Ratios (DSR), which can be used in translating from specific activity in sludge into dose to an individual. These DSR values were then combined with the results of an ISCORS survey of sludge and ash at more than 300 publicly owned treatment works, to explore the potential for radiation exposure of sludge workers and members of the public. This paper provides a brief overview of the pathway modeling methodology employed in the exposure and dose assessments and discusses technical aspects of the results obtained.

Normalization transforms the magnitude of LCI and LCIA results into relative contribution by substance and life cycle impact category. Normalization thus can significantly influence LCA-based decisions when tradeoffs exist. The U. S. Environmental Protection Agency (EPA) has developed a normalization database based on the spatial scale of the 48 continental U.S. states, Hawaii, Alaska, the District of Columbia, and Puerto Rico with a one-year reference time frame. Data within the normalization database were compiled based on the impact methodologies and lists of stressors used in TRACI-the EPA's Tool for the Reduction and Assessment of Chemical and other environmental Impacts. The new normalization database published within this article may be used for LCIA case studies within the United States, and can be used to assist in the further development of a global normalization database. The underlying data analyzed for the development of this database are included to allow the development of normalization data consistent with other impact assessment methodologies as well.

This study's objective was to determine the effects of elevated CO sub(2) on production, mortality, and standing crops of fine root length over 2 years in a free-air CO sub(2) enrichment (FACE) facility in the Mojave Desert of southern Nevada, USA. Three replicate 25 m diameter FACE rings were maintained at ambient ( similar to 370 mu mol mol super(-1)) and elevated CO sub(2) ( similar to 550 mu mol mol super(-1)) atmospheric concentrations. Twenty-eight minirhizotron tubes were placed in each ring to sample three microsite locations: evergreen Larrea shrubs, drought-deciduous Ambrosia shrubs, and along systematic community transects (primarily in shrub interspaces which account for similar to 85% of the area). Seasonal dynamics were similar for ambient and elevated CO sub(2): fine root production peaked in April-June, with peak standing crop occurring about 1 month later, and peak mortality occurring during the hot summer months, with higher values for all three measures in a wet year compared with a dry year. Fine root standing crop, production, and mortality were not significantly different between treatments except standing crop along community transects, where fine root length was significantly lower in elevated CO sub(2). Fine root turnover (annual cumulative mortality-mean standing crop) ranged from 2.33 to 3.17 year super(-1), and was not significantly different among CO sub(2) treatments, except for community transect tubes where it was significantly lower for elevated CO sub(2). There were no differences in fine root responses to CO sub(2) between evergreen (Larrea) and drought-deciduous (Ambrosia) shrubs. Combined with observations of increased leaf-level water-use efficiency and lack of soil moisture differences, these results suggest that under elevated CO sub(2) conditions, reduced root systems (compared with ambient CO sub(2)) appear sufficient to provide resources for modest aboveground production increases across the community, but in more fertile shrub microsites, fine root systems of comparable size with those in ambient CO sub(2) were required to support the greater aboveground production increases. For community transects, development of the difference in fine root standing crops occurred primarily through lower stimulation of fine root production in the elevated CO sub(2) treatment during periods of high water availability.

We administered a questionnaire on IAQ programs and practices to a representative sample of schools. Participants were asked to provide information on the use, administration, implementation, challenges, and benefits of the IAQ program in their school. We developed an IAQ Practice Index to determine the level of activity directed toward IAQ in schools. The index was computed based on responses to specific survey questions and was normalized to a range of 0 to 100. Each question was weighted qualitatively according to its contribution to strong IAQ management practices. Forty-two percent of schools in the United States have an IAQ management program, and there has been sustained growth from 1998 through 2002 in the number of schools that have such programs. Nearly half of those schools use the U.S. Environmental Protection Agency's IAQ Tools for Schools program. The IAQ Practice Index scores varied widely for schools with an IAQ management program, suggesting that having a program is not equivalent to implementing effective IAQ policies and procedures. Respondents indicated that their IAQ programs led to improved workplace satisfaction, fewer asthma attacks, fewer visits to the school nurse, and lower absenteeism. When actively supported by the school administration, an IAQ program appears to be a valuable factor in improving the learning environment for U.S. schoolchildren.

One of the beneficial use impairments at numerous AOC is 'fish tumors and other deformities'. An impairment occurs when the prevalence of fish tumors and other deformities exceeds those at unimpacted or control sites or when survey data confirm the presence of neoplastic or preneoplastic liver lesions in bullhead or white sucker Catostomus commersonii. Numerous surveys have been conducted over the years assessing neoplasia in these fishes, both liver and skin tumors. However, a major problem in comparing the results has been a lack of consistent criteria for evaluating histological changes in bullhead livers. As individual AOC develop and implement remedial action plans, realistic and attainable delisting targets need to be specified. For this to occur and be consistent from site to site there must be standardization of the criteria being used to evaluate specific impairments. In this report, specific diagnostic criteria are provided for both non-neoplastic and neoplastic proliferative hepatocellular and biliary lesions. These criteria should assist fish pathologists in describing and categorizing proliferative liver lesions from brown bullhead.

In an effort to accomplish this, EPA's Office of Research and Development (ORD) established the Environmental Monitoring and Assessment Program (EMAP). EMAP's principal goals are to develop the scientific understanding for translating environmental monitoring data from large geographic scales into assessments of current resource condition, providing the potential for forecasting future resource risks (EPA 2002). The EMAP program develops monitoring tools, design strategies, and indicators in an effort to achieve this goal. While EMAP is designed to guide monitoring efforts at a national scale, ORD initiates through the EMAP a Regional Environmental Monitoring and Assessment Program (REMAP) that evaluates and/or improves upon the EMAP concepts and tools and applies them in support of assessments at regional and smaller geographic levels.

However, progesterone itself has come into use as a therapeutic agent only recently with the development of an orally bioavailable "micronized" preparation. METHODS: The current review examines progesterone adverse effects as identified in the larger literature on the toxicity of progestational agents and pharmacokinetics. RESULTS: Progesterone has cytoplasmic and membrane receptors in a variety of reproductive and nonreproductive tissues including the brain and is a potent inhibitor of GnRH. Limited information is available on progesterone receptors and actions in the fetus. Concern about exogenous progestagen effects on fetal reproductive tract development have led to considerable human research over the years, but this literature review demonstrates that contemporary developmental toxicology research on progesterone is lacking. CONCLUSIONS: Progesterone is a potent, multi-faceted endocrine agent with an expanding therapeutic profile and a minimal scientific database for evaluating safe use during pregnancy.

Much of the information for developing the national estimate will be derived from epidemiologic data, and the primary outcome of this effort will be an estimate of the number of cases of gastrointestinal illness. While quantifying the number of these cases provides some measure of waterborne disease impact the usefulness of this measure may be limited because the full spectrum of societal impact also involves consideration of the additional effects of these diseases such as hospitalization costs and lost productivity. If decision-makers wish to compare the impact of waterborne infectious diseases to the impact of some other public health concern (e.g. to aid in resource allocation decisions), then a comparison of case numbers may prove inadequate. Case numbers alone do not provide sufficient information about the severity of different illnesses. Society may value the avoidance of a few cases of severely debilitating illness more than it values the avoidance of many cases of mild illness, in order to compare disparate public health concerns, "burden of disease" measures that incorporate indicators of disease severity, costs, or societal values may prove essential for some types of decisions. We describe epidemiologic measures of severity, quality adjusted life years (QALYs), disability adjusted life years (DALYs), willingness-to-pay, and cost-of-illness methods commonly used for burden of disease estimates, and discuss how some of these summary measures of burden might be used for waterborne disease estimates.

There have been a limited number of epidemiologic studies that have measured waterborne disease occurrence in the United States. For this analysis, we assume that certain unknown incidence of AGI in each public drinking water system is due to drinking water and that a statistical distribution of the different incidence rates for the population served by each system can be estimated to inform a mean national estimate of AGI illness due to drinking water. Data from public water systems suggest that the incidence rate of AGI due to drinking water may vary by several orders of magnitude. In addition, data from epidemiologic studies show AGI incidence due to drinking water ranging from essentially none (or less than the study detection level) to a rate of 0.26 cases per person-year. Considering these two perspectives collectively, and associated uncertainties, EPA has developed an analytical approach and model for generating a national estimate of annual AGI illness due to drinking water. EPA developed a national estimate of waterborne disease to address, in part, the 1996 Safe Drinking Water Act Amendments. The national estimate uses best available science, but also recognizes gaps in the data to support some of the model assumptions and uncertainties in the estimate. Based on the model presented, EPA estimates a mean incidence of AGI attributable to drinking water of 0.06 cases per year (with a 95% credible interval of 0.02-0.12). The mean estimate represents approximately 8.5% of cases of AGI illness due to all causes among the population served by community water systems. The estimated incidence translates to 16.4 million cases/year among the same population. The estimate illustrates the potential usefulness and challenges of the approach, and provides a focus for discussions of data needs and future study designs. Areas of major uncertainty that currently limit the usefulness of the approach are discussed in the context of the estimate analysis.

Arsenate removal is commonly performed by adsorption to hydrous ferric oxide during sweep-floc conventional treatment, and can be improved through enhanced coagulation modification options. An integrated process model including detailed process chemistry was developed and used to investigate the effect of water composition, influent pH, and silica competition on operating conditions for arsenic removal to produce a 10 mu g/L effluent arsenic concentration. Additionally, two different sets of arsenate and silica adsorption constants were used to assess qualitatively the impacts of model structure uncertainty. In general, the background inorganic concentrations, influent pH, and (for one model) silica competition increased the range of conditions under which treatment modification is required to improve removal efficiency. The treatment modifications considered include additional ferric chloride dose, acid addition, or both. For additional treatment cases, an optimization approach was used to determine the least-cost modification option to improve removal efficiency. When silica competition was not considered, the additional ferric chloride dose option was determined to be the least-cost modification for both models. When silica competition was considered, the model that predicts significant silica competition selects acid addition or both modification options at high pH and background inorganic concentrations; the other model continued to suggest only the additional ferric chloride dose option.

Epidemiologic studies of various designs can provide an estimate of the waterborne attributable risk along with other types of information. Community drinking water systems frequently improve their operations and may change drinking water treatment and their major source of water. In the United States, many of these treatment changes are the result of regulations promulgated under the Safe Drinking Water Act. A community-intervention study design takes advantage of these " natural" experiments to assess changes in health risks. In this paper, we review the community-intervention studies that have assessed changes in waterborne gastroenteritis risks among immunocompetent populations in industrialized countries. Published results are available from two studies in Australia, one study in the United Kingdom, and one study in the United States. Preliminary results from two other US studies are also available. Although the current information is limited, the risks reported in these community-intervention studies can help inform the national estimate of endemic waterborne gastroenteritis.

Included in this evaluation were a Tapered Element Oscillating Microbalance (TEOM), three Scanning Mobility Particle Sizers (SMPSs), a Condensation Particle Counter (CPC), a TSI DustTrak, a MET-One E-BAM, and two Electrical Low Pressure Impactors (ELPIs) as well as two types of time-integrated filter samplers. Of the five on-line analyzers evaluated for PM mass concentration, the TEOM was shown to have the best overall correlation to the gravimetric filter method. For measuring concentration by particle number, the two ELPIs and the Model 3936L25 SMPS provided generally comparable results during both test phases (data for the stand-alone C were invalidated).

Historically eastern and western North Pacific gray whales were managed separately because: (i) their ranges do not overlap; (ii) genetic analyses indicate that the two populations are significantly different; and (iii) eastern gray whales have increased in abundance over the past century while western gray whales have not. Here, we review gray whale migration timing and segregation, feeding and prey species, and reproduction and reproductive behaviour. For the eastern and western gray whale, we review their distribution, history of exploitation, abundance and current status, although most of what is known is founded on the better studied eastern gray whale and only implied for the lesser known western gray whale. Methods to investigate population and stock identity are reviewed including genetics, morphology, chemical signatures, carbon isotopes, parasites, photographic identification and trends in abundance. While the evidence indicates that there is at least some degree of mixing within each of the gray whale populations, no stocks or sub-stocks can be defined. Population structure is not evident in nuclear data, and because selection occurs primarily on the nuclear genome, it is unlikely that there is structuring within each population that could result in evolutionary differences. For western gray whales, there are insufficient data to assess the plausibility of stock structure within the population, owing to its extremely depleted state. Research on eastern gray whales has focused mostly on documenting changes in abundance, feeding biology and behaviour, and suggests separate breeding groups to be unlikely. Both males and females are promiscuous breeders lending little opportunity for the nuclear genome to be anything other than well mixed as is suggested by the high haplotypic diversity of the eastern population. The available data strongly indicate that western gray whales represent a population geographically isolated from eastern gray whales and therefore that the western and eastern populations should be treated as separate management units.

Our goal was to predict concentrations of NO sub(2) and benzene, toluene, ethylbenzene, o-xylene, and m,p-xylene at a total of 55 schools. The predictive equations were developed by regressing the passive monitor measurements at the 22 monitored schools on land-use variables derived from a geographic information system (GIS). These GIS-based ancillary variables included distance to the nearest border crossing, elevation, population density, distance to roads with specified traffic volumes, traffic intensity around the schools, and distance to the nearest petroleum facility. The reliability of the predictive equations was assessed at the two intensive monitoring sites. For all pollutants, the most useful predictive ancillary variables were elevation, population density, distance to a border crossing, and distance to a petroleum facility. For estimating NO sub(2), traffic intensity was also important.

Earlier papers have dealt with the 24-h integrated gravimetric samples; this report adds the continuous data (1-min resolution) using optical scattering devices (personal data RAMs, or pDRs) for personal and indoor measurements. Subjects and their households were sampled for 7 consecutive days in each of four seasons, although not all subjects completed all four seasons. Each subject completed an activity diary with 15-min resolution on each day giving his or her presence in one of six locations and describing activities with the potential for increased exposure to particles. More than 800 person- days and 1.1x10 super(6) person-min of valid personal exposures and indoor air concentrations were collected. The pDRs compared well with the PM sub(2.5) gravimetric devices, with an R super(2) of 87% compared to the indoor Harvard impactor (HI), and 70% compared to the personal exposure monitor (PEM). As found in previous studies, (and as expected due to the calibration of these devices with an aerosol of higher density than normal ambient and indoor aerosols), the pDRs overestimated the gravimetric concentrations by 20-50%. Because the correction factor varied by season and by type of sample (indoor vs. personal), no overall correction factor could be applied. The estimated mean increases in exposure during three common activities (cooking, cleaning, and personal care) were 56, 28, and 20 mu g m super(-3), respectively. Several less common activities, such as burning food and using a fireplace were found to result occasionally in very high (>1500 mu g m super(-3)) short-term peaks of exposure. Although households with smoking were ineligible for participation, two households did have significant smoking, and had the highest average personal exposures and indoor concentrations of all the study homes. The diurnal variation of personal exposures and indoor concentrations was bimodal, with peaks occurring between 10 and 11 AM and 5 and 6 PM. The "damping effect" of the home due to air exchange caused the infiltrated outdoor particles to show only a unimodal variation, with a single broad and mild peak occurring between 6 and 10 AM. A method for identifying peak concentrations due to indoor sources and personal activities was developed. Peaks due to personal activities and indoor sources occurred about 23% and 14% of the time, respectively. On average, outdoor particles contributed about half of the total personal exposures and indoor concentrations, but there was wide variation across subjects. These findings using the MIE data were then compared to previously published estimates using measurements of sulfur from the gravimetric data; good agreement (R super(2) values from 50% to 65%) was found, providing a measure of validation to both methods. Personal exposures exceeded co-located indoor concentrations by 2-3 mu g m super(-3), confirming findings of a small but statistically significant "personal cloud" for PM sub(2.5) made in previous studies using gravimetric 24-h integrating monitors.

(dwarf eelgrass) was first identified in central Oregon (USA) estuaries about 30 years ago. The autecology of this species is poorly described at the southern end of its non-native range although several process oriented studies have been conducted. I examined the production ecology of Z. japonica in the Yaquina Bay estuary. Strong seasonal patterns in light and temperature appeared to control the seasonal variations in biomass and growth. Above- and below-ground biomass ranged between 40-100 and 70-170 gdw m super(-2) respectively and seasonal changes in the root:shoot ratio were controlled by above-ground biomass dynamics. Shoot density ranged between 4000 and 11 000 shts m super(-2). Areal leaf growth ranged between 0.1 and 1.7 gdw m super(-2) d super(-1) and annual production was about 314 plus or minus 60 gdw m super(-2) y super(-1) (mean plus or minus SD). Nutrients were not limiting in this system as a result of coastal upwelling and watershed inputs. The Z. japonica population studied in Oregon exhibited different patterns of persistence, phenology and flowering intensity relative to other populations along its native and non-native range. These differences suggest that management policies developed for one site may not be appropriate for other sites. The data presented here greatly expands our knowledge base on Z. japonica and provides insight to the processes controlling the dynamics and spread of this non-indigenous seagrass.

This paper evaluates, by application to an experimental watershed, two promising distributed watershed-scale sediment models in detail: the Kinematic Runoff and Erosion (KINEROS-2) model and the Gridded Surface Subsurface Hydrologic Analysis (GSSHA) model. The physics behind each model are to some extent similar, though they have different watershed conceptualizations. KINEROS-2 was calibrated using three rainfall events and validated over four separate rainfall events. Parameters estimated by this calibration process were adapted to GSSHA. With these parameters, GSSHA generated larger and retarded flow hydrographs. A 30% reduction in both plane and channel roughness in GSSHA along with the assumption of Green-Ampt conductivity K sub(G-A) = K sub(s), where K sub(s) is the saturated conductivity, resulted in almost identical hydrographs. Sediment parameters not common in both models were calibrated independently of KINEROS-2. A comparative discussion of simulation results is presented. Even though GSSHA's flow component slightly overperformed KINEROS-2, the latter outperformed GSSHA in simulations for sediment transport. In spite of the fact that KINEROS-2 is not geared toward continuous-time simulations, simulations performed with both models over a 1 month period generated comparable results.

The terrorist attack on New York's World Trade Center (WTC) towers caused the release of an enormous quantity of pulverized building materials and combustion products into the local environment. Particulate matter (PM) from crushed WTC building materials is primarily non-respirable (>96% larger than 10 mu m mass median aerodynamic diameter [MMAD]) and composed of fibrous and nonfibrous components such as gypsum, calcite, silica, glass fibers, cellulose, and asbestos. Respirable fine WTC PM (PM sub(2.5)) may include finely crushed building materials as well as combustion products such as dioxins and polycyclic aromatic hydrocarbons (PAHs). Rescue workers at the WTC site had exposure-related increases in the incidences of nasal congestion, bronchial hyperreactivity to aerosolized methacholine, gastroesophageal reflux disease, and persistent cough. Toxicological studies in mice indicate that WTC PM sub(2.5) causes airflow obstruction above a critical dose. The review of physical characteristics and health effects of major pollutants derived from the collapse of the WTC towers has assisted in risk assessment efforts related to the collapse of large buildings.

The method uses a Box-Cox transformation, of which the parameters are found by maximizing the likelihood function over a fixed power transformation set. To estimate the mean vector and the covariance matrix, we develop an E-M algorithm solution. Given a transformation, we obtain expressions for the mean vector, covariance matrix, and the asymptotic covariance of the vector of means in the original scale. Expressions are obtained for a confidence region for the vector of means. The performance of the maximum likelihood estimation (MLE) method in selecting the correct power transformation and the coverage rate of the confidence region under several conditions are investigated in a simulation study. This method gives reliable results for finding effective transformations and the coverage rate for highly skew data sets. The method is applied to water quality monitoring data.

This observation provided new impetus to characterize the carcinogenic risk associated with oral exposure to hexavalent chromium in drinking water. Notwithstanding the well-characterized increases in cancer associated with inhalation exposure to this chemical, the marked reduction of hexavalent chromium to trivalent chromium in the stomach suggests that exposure to hexavalent chromium in drinking water may not pose a carcinogenic risk. A reevaluation of studies that investigated the toxicokinetics, the genotoxicity, and the mechanism of carcinogenicity of hexavalent chromium, as well as the available human and animal cancer studies, was undertaken to determine if there is evidence that exposure to this chemical in drinking water may pose a carcinogenic risk. Mechanistic studies suggest the potential for a carcinogenic response if hexavalent chromium enters cells. Both toxicokinetic and genotoxicity studies indicate that a portion of an orally administered dose of hexavalent chromium is absorbed and gets into cells of several tissues, causing DNA damage.

This report summarizes a study of the microbial mutagenicity of 31 pore water samples obtained from sediment affected by non-point source runoff and compares the results with those for more traditional chemical and biological indicators of sediment quality. Genotoxicity was determined pre- and post-enzyme activation using a proprietary short-term microbial assay for pore water centrifuged from sediment collected adjacent to a Florida coastal golf complex and from an urbanized bayou-estuary. Sediment and the associated pore water also were analyzed for acute toxicity to Hyallela azteca, Palaemonetes pugio, or Americamysis bahia and for benthic macroinvertebrate diversity (sediment only). Genotoxicity (direct and enzyme-activated) was detected in 4 of 17 (golf complex) and in 10 of 14 (urbanized bayou) pore water samples. The lowest toxic pore water concentrations were between 1.8% and 44.4% (direct) and between 2.6% and 25% (enzyme-activated). The results of the genotoxic assay paralleled those based on exceedance of proposed sediment quality guidelines, pore water acute toxicity and Shannon-Wiener diversity index values for 81%, 58%, and 65% of the comparisons, respectively.

In addition, other chemical and meteorological parameters were measured concurrently. These data were analyzed using principal components analysis (PCA) in order to develop source receptor relationships for mercury species in urban Detroit. Reactive gaseous mercury (RGM) was found to cluster on two main factors; photochemistry and a coal combustion factor. Particulate phase mercury, Hg sub(p), tended to cluster with RGM on the same factor. The photochemistry factor corroborates previous observations of the presence of RGM in highly oxidizing atmospheres and does not point to a specific source emission type. Instead, it likely represents local emissions and regional transport of photochemically processed air masses. The coal combustion factor is indicative of emissions from coal-fired power plants near the receptor site. Elemental mercury was found on a factor for combustion from automobiles and points to the influence these emissions have on the receptor site, which was located proximate to two major interstate highways and the largest border crossing in the United States. This analysis reveals that the receptor site which is located in an industrialized sector of the city of Detroit experienced impacts from both stationary and point sources of mercury that are both local and regional in nature.

Simulated surface O sub(3) concentrations are compared with 987 Air Quality System (AQS) sites and 123 Clean Air Status and Trends Network (CASTNet) sites. CMAQ's ability to reproduce surface observations varies with O sub(3) concentration. The model best simulates observed O sub(3) for intermediate concentrations (40-60 ppbv), while over-(under-) predicting at lower (higher) levels. CMAQ reproduces surface O sub(3) for a wide range of conditions (30-80 ppbv) with a normalized mean error (NME) less than 35% and normalized mean bias (NMB) lying between +/- 15% for the whole domain. Although systematically over-predicting O sub(3) in the east and under-predicting it in the western United States, CMAQ is able to reproduce 1- and 8-h daily maxima with a cross-domain mean bias (MB) of 1 and 8 ppbv, or NMB of 8% and 25%, respectively. The model underestimates observed O sub(3) at rural sites (MB=-5 ppbv, NMB=-5% and NME=23% with a 40 ppbv cut-off value) and over-predicts it at urban and suburban sites by a similar magnitude (MB=6 ppbv, NMB=7% and NME=25%). Apparent errors and biases decrease when data is averaged over longer periods, suggesting that most evaluation statistics are dependent on the time scale of data aggregation. Therefore, performance criteria should specify an averaging period (e.g., 1- or 8- h) and not be independent of averaging period as some current model evaluation studies imply. Comparisons of vertical profiles of simulated O sub(3) with ozonesonde data show both overestimation and underestimation by 10-20 ppbv in the lower troposphere and a consistent under-prediction in the upper troposphere. Vertical O sub(3) distributions are better simulated when lateral boundary conditions obtained from the global Model of Ozone and Related Tracers version 2 (MOZART-2) are used, but under-prediction remains. The assumption of zero-flux at the top boundary and the resulting exclusion of the contribution of stratosphere- troposphere exchange to tropospheric O sub(3) concentrations limit the ability of CMAQ to reproduce O sub(3) concentrations in the upper troposphere.

The interaction between ground water and surface water has a significant influence on iron sulfide formation in the wetland sediments. Ground-water seeps supply concentrations of sulfate, dissolved hydrocarbons, ferrous iron, and arsenic, and sediments located near seeps are anomalously enriched in arsenic, reactive iron, and acid-volatile sulfides. Degree-of-sulfidation (DOS) values are high in sediments adjacent to sites of ground-water discharge, ranging from 0.57 to 1.0. Pyrite (FeS sub(2)) formation is apparently not limited by the abundance of any one primary reactant, e.g., organic carbon, sulfate, or reactive iron; instead, persistence of precursor iron monosulfides is attributed to slow pyrite formation kinetics due to low concentrations of reactive intermediate sulfur species or possibly due to high concentrations of arsenite, dissolved organic-carbon, or other solutes that adsorb to iron monosulfides surfaces and impede transformation reactions to pyrite. Greigite (Fe sub(3)S sub(4)) accounts for > 80% of total reduced sulfur in sediments rich in acid-volatile sulfide and X-ray absorption spectroscopy data for magnetic separates provide direct evidence that As(III) is, at least in part, associated with reduced sulfur in the form of greigite. However, pyrite can only account for a small percentage, - 20%, of the total arsenic budget in the reduced sediments. Although pyrite is the predicted stable endpoint for reactive iron and sulfur, it appears that within a 30 y time period pyrite is a relatively unimportant host for arsenic in the system investigated here. The abundance of reactive iron in the sediments prevents accumulation of dissolved sulfide and thus prevents formation of soluble thioarsenic species. X-ray absorption near-edge structure (XANES) spectroscopy indicates only the presence of As(III) in the reduced sediments. Results of linear combination fitting of reference spectra to sediment spectra are consistent with sulfur- and/or oxygen- coordinated As(III) in association with iron monosulfides and ferrous-bearing carbonates or hydroxides.

Past Great Lakes work has focused on enumerating frequencies of oscillation but without addressing their combined influence. Information on seiche magnitude is sparse and focused on extremes rather than typical levels, and tools that integrate magnitude and frequency components to derive net day-scale effects are lacking. This study uses water level time series to characterize daily fluctuation regimes for 51 stations around the Great Lakes. Distributions of fluctuation magnitude typically had long upper tails, with some level of activity always present. Logarithmic mean daily water level range varied from similar to 4 cm in Lake Ontario to > 20 cm in Lake Erie, with largest values at the ends of lakes and in large bays. Oscillation frequency patterns were spatially variable and had both seiche and tide components. One-half the daily sum of water level increments is a computationally tractable metric of fluctuation intensity that integrates magnitude and frequency. This metric is directly interpretable as the column of water moved by all seiche and tide modes combined, which when multiplied by an area of interest yields the volume of water involved. Logarithmic mean values for this metric ranged from similar to 10 cm in Lake Ontario to > 50 cm in Lake Erie. Data and tools provided will support future efforts to establish seiche and tide influences on Great Lakes wetlands and embayments.

Field and laboratory observations indicate that arsenic solubility was controlled, in part, by the extent of ferrous iron oxidation-precipitation and arsenic sorption occurring near the lake chemocline. Laboratory experiments were conducted using site-derived water to assess the impact of these coupled processes on the removal of dissolved arsenic from the water column. The measured concentration of organic carbon from epilimnetic and hypolimnetic water sampled from the lake was approximately 1.3 mM and 17.0 mM, respectively. Experiments conducted with these samples along with synthetic controls containing no organic carbon demonstrated that observed rates of formation and crystallinity of the precipitated iron (hydr)oxide were dependent on the concentration of organic carbon in the lake water. Increasing dissolved organic matter concentration did not significantly interfere with ferrous iron oxidation, but inhibited iron (hydr)oxide precipitation and subsequent sorption of arsenic. For experiments using water sampled from the lake hypolimnion there was a strong relationship between the fraction of precipitated iron and the fraction of sorbed arsenic. Laboratory- and field-derived iron (hydr)oxide precipitates were characterized to evaluate mineralogy and arsenic distribution. In-situ suspended solids and precipitates formed in laboratory experiments using hypolimnetic water were identified as poorly crystalline 2-line ferrihydrite. These solids were readily dissolved in the presence of dithionite indicating that elevated dissolved iron and arsenic observed in the hypolimnion resulted, in part, from in-situ reductive dissolution of settling 2-line ferrihydrite near the sediment-water interface. These observations support the contention that the levels of dissolved arsenic observed in the shallow lake can be attributed to ground-water discharge and internal recycling of arsenic within the water column. The efficiency of the process resulting in iron (hydr)oxide precipitation and arsenic sorption limits the downgradient export of arsenic derived from ground-water discharge.

AN - 68791956; 16282161 AB - Accurate quantification of the dose delivered by aerosol exposures is essential for estimating the risk of potential adverse health effects. The fraction of airborne particles that can enter the nose or mouth during inhalation is referred to as the inspirable particulate mass fraction. This inhalable fraction is equivalent to delivered dose for particles greater than approximately 25 microm (aerodynamic particle diameter, d(ae)), which deposit completely and almost exclusively in the extrathoracic airways. Particle inhalability at high wind speeds (1-9 m/s) has been well characterized. However, there is a paucity of data describing the inhalability of particles at low wind speeds (< or =0.3 m/s), which are typical of indoor environments. High-wind-speed criteria poorly describe inhalability at low wind speeds. Based on the aspiration efficiencies of blunt and sharp-edged inlets, a function was developed for oral inhalability, P(I(O)), of particles at low wind speeds. This function predicts a slow decline in P(I(O)) from 0.95 at d(ae)= 8 microm, to 0.5 at d(ae) = 74 microm, and 0.1 at d(ae)= 175 microm. Data available from the literature for inhalability at relatively low wind speeds during oral breathing are well described by this logistic function (r(2)= 0.69).

13771301 AB - New Bedford Harbor (NBH), MA, is a Superfund site because of high polychlorinated biphenyl (PCB) concentrations in the sediment. From April 1994 to September 1995, a remedial dredging operation (termed the "Hot Spot") removed the most contaminated sediments (PCB concentrations greater than 4000kg/g) from the upper harbor. During remediation, a monitoring program assessed the potential environmental impacts to NBH and adjacent Buzzards Bay. The monitoring program was developed with input from federal, state, and local authorities. Site-specific decision criteria were established to assess net PCB transport, water column toxicity, and PCB bioaccumulation in blue and ribbed mussels (Mytilus edulis and Geukensia demissa, respectively). The remediation was completed without exceeding PCB net transport or acute toxicity effects specified in the decision criteria. In addition, PCB bioaccumulation in mussels during this time period was not significantly greater than pre- or post-operational measurements. The results indicated that approximately 14000 cubic yards of highly PCB contaminated sediment were permanently removed with minimal environmental effects. The lessons learned during this operation, as well as previous pilot studies at the site, will be used to make full-scale remedial efforts in NBH more efficient and environmentally protective.

AN - 70126583; 16388840 AB - Agonists and antagonists at the NMDA, GABA, and nicotinic acetylcholine receptors were administered to adult male rats to evaluate the contribution of these pathways to the visual-evoked potential (VEP). Rats were presented with an onset/offset pattern at a temporal frequency (4.55 Hz) resulting in a steady-state VEP. Averaged VEPs were Fourier transformed and VEP amplitudes were calculated at 1x stimulus frequency (F1) and 2x stimulus frequency (F2). About 30 min after administration, NMDA (10 mg/kg, i.p.; n = 9) increased F1 amplitude by 350% and decreased F2 amplitude by 48%. Memantine (4.5 mg/kg, i.p.; n = 10) increased F1 amplitude by 50%, 10 min post-injection. Similarly, nicotine (0.1 mg/kg, s.c.; n = 9) increased F1 amplitude by 55%, 20 min after drug administration. Muscimol (1 mg/kg, i.p.; n = 10) increased F1 amplitude significantly from 20 to 45 min post-injection. Mecamylamine (6 mg/kg, i.p.; n = 10) decreased F2 amplitude by 70% during the 60-min testing session. Bicuculline (0-0.5 mg/kg, i.p.; n = 8-10 rats/dose) did not significantly alter either F1 or F2 amplitudes. Results indicate important roles for glutamate and nicotinic acetylcholine receptors in both F1 and F2, while GABA receptors contribute to F1.

AN - 69078445; 16424281 AB - Dietary restriction of calories (caloric restriction [CR]) increases longevity in phylogenetically diverse species. CR retards or prevents age-dependent deterioration of tissues and an array of spontaneous and chemically induced diseases associated with obesity including cardiovascular disease, diabetes, and cancer. An understanding of the molecular mechanisms that underlie the beneficial effects of CR will help identify novel dietary, pharmacological, and lifestyle strategies for slowing the rate of aging and preventing these diseases as well as identify factors which modulate chemical toxicity. Here, we review the involvement of transcriptional coactivator proteins, peroxisome proliferator-activated receptor (PPAR) gamma coactivator 1 (PGC-1) alpha and beta, and regulated nuclear receptors (NR) in mediating the phenotypic changes found in models of longevity which include rodent CR models and mouse mutants in which insulin and/or insulin-like growth factor-I signaling is attenuated. PGC-1alpha is transcriptionally or posttranslationally regulated in mammals by: 1) forkhead box "other" (FoxO) transcription factors through an insulin/insulin-like growth factor-I -dependent pathway, 2) glucagon-stimulated cellular AMP (cAMP) response element binding protein, 3) stress-activated kinase signaling through p38 mitogen-activated protein kinase, and 4) the deacetylase and longevity factor sirtuin 1 (SIRT1). PGC-1alpha and PGC-1beta regulate the ligand-dependent and -independent activation of a large number of NR including PPARalpha and constitutive activated receptor (CAR). These NR regulate genes involved in nutrient and xenobiotic transport and metabolism as well as resistance to stress. CR reverses age-dependent decreases in PGC-1alpha, PPARalpha, and regulated genes. Strategies that target one or multiple PGC-1-regulated NR could be used to mimic the beneficial health effects found in models of longevity. JF - The journals of gerontology.

AN - 69044952; 16382954 AB - Reductive biotransformation of tetrachloroethene (PCE) to ethene occurred during anaerobic degradation of toluene in an enrichment culture. Ethene was detected as a dominant daughter product of PCE dechlorination with negligible accumulation of other partially chlorinated ethenes. PCE dechlorination was linked to toluene degradation, as evidenced by the findings that PCE dechlorination was limited in the absence of toluene but was restored with a spike of toluene again in the cultures. PCE was effectively dechlorinated in cultures amended with a wide range of concentrations of PCE and toluene. PCE dechlorination can be described by a Monod-like equation but followed a zero-order kinetic at high levels of PCE. In addition to toluene, benzoate and lactate were also able to be used as sole electron donors for reductive dechlorination of PCE in the cultures. In terms of dechlorination rates, lactate was the best electron donor followed by benzoate and then toluene. The kinetic characteristics of PCE dechlorination were retained in the cultures regardless of electron donors used, but the kinetic constant values were unique to each electron donor. The dechlorination rate was found to be closely correlated with the level of H2 produced during fermentation of the three organic compounds. Nitrate and sulfate were observed to be favorable electron acceptors in this culture, and their presence completely blocked electron flow to PCE. However, the presence of nitrate and sulfate did not destroy the capability of PCE dechlorination by the culture. PCE dechlorination was immediately reestablished after depletion of nitrate and sulfate in the culture. This anaerobic process provides an opportunity for concurrent remediation of chlorinated solvents and certain fuel hydrocarbons, and recognition of this process is also important in understanding the subsurface fate and transport of these contaminants under natural conditions.

AN - 69044799; 16382950 AB - Automated speciated mercury measurements were made at a rural (Dexter, MI) and an urban (Detroit, MI) site in Michigan during selected times from 1999 to 2002 to assess the concentrations of elemental (Hg0), reactive gaseous (RGM), and particulate mercury (Hgp) in these environments. Here we present the first-ever reported values for RGM in Michigan. Median RGM concentrations were 2.21-2.93 pg m(-3) at Dexter and were 3-11 times higher in Detroit at 6.41-22.0 pg m(-3). Maximum RGM concentrations of 38.7 pg m(-3) and 270 pg m(-3) were observed in Dexter and Detroit, respectively. Measured RGM/Hg0 ratios were in the range of 0.04-11.60% indicating that at times RGM comprises greater than the currently held view of 5% of total gaseous mercury in the air. Well-pronounced diurnal patterns of RGM were observed at the rural site, whereas the urban site exhibited patterns that were influenced by nighttime emissions and regional transport. An analysis of RGM/Hgp ratios at the urban site when combined with trajectory analysis suggests that the site receives mercury inputs from both local and regional sources. Episodes of elevated ozone concentrations which were accompanied by increases in RGM concentrations were observed to occur in the late afternoon and overnight. These may be evidence of advection of ozone and RGM over long distances to the site.

AN - 68904954; 16359172 AB - The reaction of dimethylarsinic acid (DMAV) with hydrogen sulfide (H2S) is of biological significance and may be implicated in the overall toxicity and carcinogenicity of arsenic. The course of the reaction in aqueous phase was monitored, and an initial product, dimethylthioarsinic acid, was observed by using LC-ICP-MS and LC-ESI-MS. Dimethylarsinous acid was observed as a minor product. A second slower-forming product was identified, and the electrospray mass chromatograms for this species produced ions at m/z 275, 171, and 137 in positive mode. To aid in the identification of this slower-forming product, crystalline standards of sodium dimethyldithioarsinate and dimethylarsino dimethyldithioarsinate were prepared and re-characterized by using improved spectroscopic and structural analysis techniques. An aqueous solution of sodium dimethyldithioarsinate produced a single major chromatographic peak that matched the retention time (7.6 min) of the slower-forming product and contained similar molecular ions at m/z 275, 171, and 137 via LC-ESI-MS. The dimethylarsino dimethyldithioarsinate standard produced four aqueous phase species one of which coeluted with the slower forming product. This coeluting peak also produced the identical ESI-MS ions as the slower-forming product of DMAV + H2S. ESI-MS/MS experiments conducted on sodium dimethyldithioarsinate in deuterated water produced molecular ions at m/z 276, 173, and 137. Subsequent collisionally activated dissociation (CAD) experiments on m/z 276 did not produce a product ion at m/z 173. These data indicate that two different species are present in solution, while NMR data indicate that only dimethyldithioarsinic acid exists in aqueous solutions. This discrepancy was investigated by conducting NMR studies on the acidic solution of sodium dimethyldithioarsinate after taking this solution to dryness. The resolubilized solution produced a proton NMR signal characteristic of dimethylarsino dimethyldithioarsinate. Therefore, it was concluded that the ESI-MS ion at m/z 275 associated with the slowly forming second reaction product and the sodium dimethyldithioarsinate compound is a product of the ESI desolvation process.

AN - 68870203; 16330353 AB - Ozone is an oxidant gas that can directly induce lung injury. Knowledge of the initial molecular events of the acute O3 response would be useful in developing biomarkers of exposure or response. Toward this goal, we exposed rats to toxic concentrations of O3 (2 and 5 ppm) for 2 hr and the molecular changes were assessed in lung tissue 2 hr postexposure using a rat cDNA expression array containing 588 characterized genes. Gene array analysis indicated differential expression in almost equal numbers of genes for the two exposure groups: 62 at 2 ppm and 57 at 5 ppm. Most of these genes were common to both exposure groups, suggesting common roles in the initial toxicity response. However, we also identified the induction of nine genes specific to 2-ppm (thyroid hormone-beta receptor c-erb-A-beta; and glutathione reductase) or 5-ppm exposure groups (c-jun, induced nitric oxide synthase, macrophage inflammatory protein-2, and heat shock protein 27). Injury markers in bronchoalveolar lavage fluid (BALF) were used to assess immediate toxicity and inflammation in rats similarly exposed. At 2 ppm, injury was marked by significant increases in BALF total protein, N-acetylglucosaminidase, and lavageable ciliated cells. Because infiltration of neutrophils was observed only at the higher 5 ppm concentration, the distinctive genes suggested a potential amplification role for inflammation in the gene profile. Although the specific gene interactions remain unclear, this is the first report indicating a dose-dependent direct and immediate induction of gene expression that may be separate from those genes involved in inflammation after acute O3 exposure.

AN - 68802487; 16109744 AB - The mechanisms underlying the acute neurophysiological and behavioral effects of volatile organic compounds (VOCs) remain to be elucidated. However, the function of neuronal ion channels is perturbed by VOCs. The present study examined effects of toluene (TOL), trichloroethylene (TCE), and perchloroethylene (PERC) on whole-cell calcium current (ICa) in nerve growth factor-differentiated pheochromocytoma (PC12) cells. All three VOCs affected ICa in a reversible, concentration-dependent manner. At +10-mV test potentials, VOCs inhibited ICa, whereas at test potentials of -20 and -10 mV, they potentiated it. The order of potency for inhibition (IC50) was PERC (270 microM) > TOL (720 microM) > TCE (1525 microM). VOCs also changed ICa inactivation kinetics from a single- to double-exponential function. Voltage-ramp experiments suggested that VOCs shifted ICa activation in a hyperpolarizing direction; this was confirmed by calculating the half-maximal voltage of activation (V1/2, act) in the absence and presence of VOCs using the Boltzman equation. V(1/2, act) was shifted from approximately -2 mV in control to -11, -12, and -16 mV by TOL, TCE, and PERC, respectively. Similarly, VOCs shifted the half-maximal voltage of steady-state inactivation (V1/2, inact) from approximately -16 mV in control to -32, -35, and -20 mV in the presence of TOL, TCE, and PERC, respectively. Inhibition of ICa by TOL was confirmed in primary cultures of cortical neurons, where 827 microM TOL inhibited current by 61%. These data demonstrate that VOCs perturb voltage-sensitive Ca2+ channel function in neurons, an effect that could contribute to the acute neurotoxicity of these compounds.

AN - 68644030; 16195206 AB - Several features of the clinical presentation and changes in physiology and pathology following exposure to many diverse ambient air pollution particles are comparable, suggesting a common mechanism for their biological effect. We propose that a mechanism of biological effect common to many ambient air pollution particles is a disruption of iron homeostasis in cells and tissues. Among traits shared by every particle-related lung injury is the introduction of a solid-liquid interface into the respiratory tract. All surfaces of particulate matter have some concentration of oxygen-containing functional groups. As a result of its electropositivity, Fe(3+) has a high affinity for oxygen-donor ligands and will react with these groups at the particle surface. Retained particles accumulate metal from available sources in a cell and tissue, and this complexed iron mediates oxidant generation. In addition to complexation onto the solid-liquid interface provided by the surface of particulate matter (PM), there are several alternative pathways by which metal homeostasis in the lower respiratory tract can be disrupted following exposure to ambient air pollution particles to affect an oxidative stress. Evidence suggests that disruption in iron homeostasis following exposures to ambient air pollution particles is an initial event in their biological effect. An association between metal equilibrium in the lower respiratory tract and biological effect in the lung could explain the observed differential toxicity of ultrafine, fine, and coarse particles and disparities in host susceptibility.

Nitrogen dioxide (NO2) is one of the six criteria pollutants regulated by the 1970 Clean Air Act where National Ambient Air Quality Standards were established to protect public health and welfare. We use patent data to show that in the cases of Japan, Germany, and the United States, innovations in NOx control technologies did not occur until stringent government regulations were in place, thus "forcing" innovation. We also demonstrate that reductions in the capital and operation and maintenance (O&M) costs of new generations of high-efficiency NOx control technologies, selective catalytic reduction (SCR), are consistently associated with the increasing adoption of the control technology: the so-called learning-by-doing phenomena. The results show that as cumulative world coal-fired SCR capacity doubles, capital costs decline to 86% and O&M costs to 58% of their original values. The observed changes in SCR technology reflect the impact of technological advance as well as other factors, such as market competition and economies of scale.

Approximate expressions for the arithmetic and geometric statistics of G are also obtained, which compare favourably with MC generated ones. This paper also applies the MC method to evaluate parameter sensitivity and predictive uncertainty of the distributed runoff and erosion model KINEROS2 in a small experimental watershed. The MC simulations of flow and sediment related variables show that those parameters which impart the greatest uncertainty to KINEROS2 model outputs are not necessarily the most sensitive ones. Soil hydraulic conductivity and wetting front net capillary drive, followed by initial effective relative saturation, dominated uncertainties of flow and sediment discharge model outputs at the watershed outlet Model predictive uncertainty measured by the coefficient of variation decreased with rainfall intensity, thus implying improved model reliability for larger rainfall events. The antecedent relative saturation was the most sensitive parameter in all but the peak arrival times, followed by the overland plane roughness coefficient. Among the sediment related parameters, the median particle size and hydraulic erosion parameters dominated sediment model output uncertainty and sensitivity. Effect of rain splash erosion coefficient was negligible. Comparison of medians from MC simulations and simulations by direct substitution of average parameters with observed flow rates and sediment discharges indicates that KINEROS2 can be applied to ungauged watersheds and still produce runoff and sediment yield predictions within order of magnitude of accuracy.

Design and method: National survey data of work experiences were collected from hospital nurses working at 124 hospital wards in 36 departments in 15 hospitals across Norway during the autumn of 1998. The multilevel structure of the variation of nine indices of job satisfaction was explored by fitting four-level random intercept models (nurse, ward, department and hospital). Results: A total of 2606 nurses (66%) responded. The indices showed varying clustering to organizational units. Intraclass correlations (ICCs) varied from 0.05 to 0.38, representing considerable higher level variation. The ward level was the dominating level for the clustering of nurses' job aspect evaluations. Conclusion: Multilevel modelling of staff work experiences may identify which improvement goals can be addressed at which organizational level. Improvement efforts should be directed specifically towards each aspect of work and at its most relevant organizational level. Strategies aimed at the micro-organizational level (ward management) rather than the individual level or the macro level (hospital top management) might prove worthwhile.

Point observations of flower-visiting bees were made along transects in three communities with different degrees of human-induced ecosystem disturbance. The community with the greatest anthropogenic disturbance had lower overall species richness of stingless bees and the highest degree of dominance of the Africanized honeybee (Apis mellifera scutellata), while the area with the most intact ecosystem had the highest diversity of stingless bees, though A. mellifera was still the dominant species. We observed aggressive competitive behavior involving physical attacks by A. mellifera against stingless bees, indicating that Africanized honeybees are adopting new behaviors to compete better with dominant native pollinator species.Original Abstract: Este estudio, realizado en el estado de Quintana Roo, Mexico, tuvo como objetivo determinar las causas del reciente desplazamiento de las abejas sin aguijon (Meliponinae) en la region del Yucatan y los efectos de la destruccion del ecosistema sobre la diversidad de las abejas. Los metodos de investigacion incluyeron observaciones de polinizadores visitando plantas a lo largo de transectos en tres comunidades con diversos grados de alteracion del ecosistema. La comunidad con el mayor grado de perturbacion ecosistemica tuvo menos riqueza de especies de abejas sin aguijon y un alto grado de dominancia de la abeja africanizada (Apis mellifera scutellata), mientras que el sitio con el ecosistema mejor conservado tuvo la mayor diversidad de abejas sin aguijon, aunque Apis mellifera siguio siendo la especie dominante. En varias ocasiones se observo un comportamiento agresivo involucrando ataques fisicos de Apis mellifera contra abejas sin aguijon el cual representa un nuevo patron de comportamiento para las abejas Apis. Estas observaciones indican que las abejas africanizadas estan adoptando nuevos comportamientos para competir mejor con las otras especies de polinizadores dominantes.

Consistent with the goal of obtaining scientifically sound test data for hazard and risk assessment of chemicals, changes are being made in current policies and procedures to facilitate the acceptance of data developed using these methods. National and international organizations are developing policies and standards for scientific practice to assure quality in implementation of in vitro methods. Consensus is developing in the scientific community for the quality control measures needed for in vitro methods; including appropriate controls, data reporting elements, and benchmarks to be identified in test guidelines so that the potential risks of chemicals can be reviewed and reliably assessed. Additional guidance to the OECD's Good Laboratory Practice principles [Organization for Economic Cooperation and Development (OECD, 2004. Advisory Document of the Working Group on Good Laboratory Practice: The Application of the Principles of GLP to in vitro Studies. OECD Series on Principles of Good Laboratory Practice and Compliance Monitoring Number 14 (ENV/JM/MONO(2004)26). Paris, France] will help to ensure that in vitro tests used for regulatory purposes are reproducible, credible, and acceptable. Generic test guidelines incorporating performance standards are being written to allow acceptance of proprietary test methods by regulatory agencies and to provide assurance that any in vitro system performs over time in a manner that is consistent with the test system as it was originally validated.

Experiments were designed to define the degree of additive joint toxicity for mixtures of specific xenobiotics that are believed to act through a similar or different primary mode of toxic action. Our results support the general conclusion that concentration addition is expected for the joint toxicity of similarly acting toxicants. When chemicals were thought to act by a dissimilar mechanism, the combined effects we observed at both of the response levels tested were less than predicted by concentration addition, but usually more toxic than that predicted by the independent action/response addition model. It was demonstrated in multichemical mixtures that several toxicants can act together in a nearly additive fashion to produce effects even when they are present at concentrations below their individual no-observed-effect concentration. Concentration-response relationships for test chemicals at both the lethal and sublethal responses were defined for each of the three modes of toxic action studied. When normalized for potency, it was observed that one relationship could be defined to predict lethality to juvenile fathead minnows when exposed to individual chemicals with either a narcosis I, narcosis II, or uncoupler mode of toxic action. These sublethal relationships were similar for the narcosis I and narcosis II test chemicals, but a steeper response was observed for tests conducted with uncouplers.

It is intuitive that an increased proportion of impervious surface brings with it shorter lag times between onset of precipitation and subsequently higher runoff peaks and total volume of runoff in receiving waters. Yet, documentation on quantitative relationships between the extent and type of impervious area and these hydrologic factors remains dispersed across several disciplines.

RNA from HBECs exposed to vehicle, V (50 mu M), or Zn (50 mu M) for 4 hr (n = 4 paired experiments) was hybridized to Affymetrix Hu133A chips. Using one-class t-test with p < 0.01, we identified 140 and 76 genes with treatment:control ratios greater than or equal to 2.0 or less than or equal to 0.5 for V and Zn, respectively. We then categorized these genes into functional pathways and compared the number of genes in each pathway between V and Zn using Fisher's exact test. Three pathways regulating gene transcription, inflammatory response, and cell proliferation distinguished V from Zn. When genes in these three pathways were matched with the 163 genes flagged by the same statistical filtration for V:Zn ratios, 12 genes were identified. The hierarchical clustering analysis showed that these 12 genes discriminated V from Zn and consisted of two clusters. Cluster 1 genes (ZBTB1, PML, ZNF44, SIX1, BCL6, ZNF450) were down-regulated by V and involved in gene transcription, whereas cluster 2 genes (IL8, IL1A, PTGS2, DTR, TNFAIP3, CXCL3) were up-regulated and linked to inflammatory response and cell proliferation. Also, metallothionein 1 genes (MT1F, MT1G, MT1K) were up-regulated by Zn only. Thus, using microarray analysis, we identified a small set of genes that may be used as biomarkers for discriminating V from Zn. The novel genes and pathways identified by the microarray may help us understand the pathogenesis of health effects caused by environmental V and Zn exposure.

Recent data suggest a dose-dependent elimination rate for TCDD. A physiologically based pharmacokinetic (PBPK) model, which uses a body-burden-dependent elimination rate, was developed previously in rodents to describe the pharmacokinetics of TCDD and has been extrapolated to human exposure for this study. Optimizations were performed using data from a random selection of veterans from the Ranch Hand cohort and data from a human volunteer who was exposed to TCDD. Assessment of this PBPK model used additional data from the Ranch Hand cohort and a clinical report of two women exposed to TCDD. This PBPK model suggests that previous exposure assessments may have significantly underestimated peak blood concentrations, resulting in potential exposure misclassifications. Application of a PBPK model that incorporates an inducible elimination of TCDD may improve the exposure assessments in epidemiologic studies of TCDD.

The objective of this study was to identify the operational and water quality factors that impact arsenic removal during iron removal. Bench-scale ('batch' and standard jar) tests were used to evaluate the effects of pH, phosphate, other water chemistry variables, and the oxidant used to oxidize Fe(II) on the removal of arsenic. Treatment operation considerations, including sequence of oxidant addition and contact time, were also considered. Results showed that (1) arsenic removal improves with increasing iron concentration and particle surface area; (2) freshly precipitated iron particles had a much greater capacity to remove arsenic than preformed particles that were formed by oxidation of ferrous iron with either oxygen or chlorine; (3) chlorination, or application of a stronger oxidant, may be necessary to improve arsenic removal at many drinking water treatment plants; (4) the point of strong oxidant addition in the treatment train is important; and (5) the pH and other competing water quality variables such as phosphate play significant roles in the amount of arsenic removed.

An inverse modelling approach that estimates the hydraulic structure and NAPL architecture based on a Lagrangian stochastic model where the hydraulic structure is described by one or more populations of lognormally distributed travel times and the NAPL architecture is selected from eight possible assumed distributions. Optimization of the model parameters for each tested realization is based on the minimization of the sum of the square residuals between the log of measured tracer data and model predictions for the same temporal observation. For a given NAPL architecture the error is reduced with each added population. Model selection was based on a fitness which penalized models for increasing complexity. The technique is demonstrated under a range of hydrologic and contaminant settings using data from three small field-scale tracer tests: the first implementation at an LNAPL site using a line-drive flow pattern, the second at a DNAPL site with an inverted five-spot flow pattern, and the third at the same DNAPL site using a vertical circulation flow pattern. The Lagrangian model was capable of accurately duplicating experimentally derived tracer breakthrough curves, with a correlation coefficient of 0.97 or better. Furthermore, the model estimate of the NAPL volume is similar to the estimates based on moment analysis of field data. Abstract Copyright (2005) Elsevier, B.V.

AN - 68693575; 16122865 AB - Gene expression profiling has been shown to be useful for identifying underlying mechanisms of toxicity, determining patterns of biological response, and elucidating candidate markers of exposure and response. Inorganic arsenic (iAs) is a human carcinogen and epidemiologic evidence implicates it in the development of urinary bladder cancer. Dimethylarsinic acid (DMA), the major excreted metabolite of iAs in humans, is a known rat bladder carcinogen. To examine the changes associated with DMA exposure, microarray analysis of the urothelium was performed in female F344 rats exposed to non-toxic and toxic doses of DMA in their drinking water for 28 days. A novel method for isolating predominantly urothelial cells was developed. Gene expression profiling of the urothelium using a custom 2-dye spotted array revealed that DMA treatment modulated the expression of transcripts of genes that regulate apoptosis, cell cycle regulation and the oxidative stress response. Expression of genes mapping to pathways involved in cancer control processes were also altered after DMA exposure. Morphological data suggested a dose dependent increase in cellular toxicity. Significant changes in differential gene expression were present after all treatments event at doses where standard toxicological responses were not detectable. The greatest perturbation in gene expression was present in rats after treatment with 40 ppm DMA. Doses which produced no histologic or ultrastructural evidence of toxicity (non-toxic) could be differentiated from toxic doses based on the expression of a subset of genes, which control cell signaling and the stress response. These reported changes in gene expression show similarities between the mechanisms of action of DMA in vivo and those previously described for iAs in vitro. These data illustrate the utility of transcriptional profiling and its potential in predicting key mechanistic pathways involved in toxicity and as a time efficient tool to inform the mode of action analysis in risk assessment.

The objectives were to simulate, to the extent possible, the combustion of such waste wood as might occur in an open field or someone's backyard; to characterize the composition and particle size distribution (PSD) of the emitted fly ash; to determine the partitioning of arsenic, chromium, and copper between the fly ash and residual ash; and to examine the speciation of the CCA elements. This work reports preliminary air emission concentrations and estimated emission factors for total particulate matter, arsenic (As), chromium (Cr), copper (Cu), and polychlorinated dibenzodioxins/dibenzofurans (PCDD/F) totals and toxic equivalents (TEQs). The partitioning of As, Cr, and Cu between the emitted fly ash and residual ash is examined and thermochemical predictions from the literature are used to explain the observed behavior. Results indicate a unimodal fly ash PSD between 0.1 and 1.0 mu m diameter. In addition to a large carbonaceous component, between 11 and 14% of the As present in the burned CCA treated wood was emitted with the air emissions, with the remainder present in the residual ash. In contrast, less than 1% of both the Cr and Cu present in the wood was emitted with the air emissions. PCDD/F levels were unremarkable, averaging 1.7 ng TEQ/kg of treated wood burned, a value typical for wood combustion. Scanning electron microscopy (SEM) was unable to resolve inorganic particles consisting of Cu, Cr, or As in the wood samples, but X-ray absorption fine structure (XAFS) spectroscopy confirmed that the oxidation states of the CCA elements in the wood were Cu super(2+), Cr super(3+), and As super(5+). SEM examination of the fly ash samples revealed some inorganic microcrystals within the mostly carbonaceous fly ash, while XAFS spectroscopy of the same samples showed that the oxidation states after combustion were mixed Cu super(2+), and Cu super(2+), Cr super(3+), and mixed As super(3+) and As super(5+). Estimates of the ratios of the mixed oxidation states based on the XAFS spectra were As super(3+)/(total As) = 0.8-0.9 and Cu super(+)/(total Cu) = 0.65-0.7. The Cu and Cr present in the fly ash were determined to coexist predominantly in the two oxide phases CuCrO sub(2) and CuCr sub(2)O sub(4). These results indicate that the open burning of CCA-treated wood can lead to significant air emissions of the more toxic trivalent form of As in particle sizes that are most respirable.

14116238 AB - Karst in Shanxi Province is representative of that in northern China, and karst water systems discharge in the form of springs that are among the most important sources for local water supply. Since the 1950s, attenuation has been the major trend of discharge variation of most karst springs at Shanxi. Based on the case study of 7 karst springs including Niangziguan, Xin'an, Guozhuang, Shentou, Jinci, Lancun, and Hongshan springs, the discharge variation process of karst springs was divided into natural fluctuation phase and anthropogenic impact phase. Discharge attenuation of the 7 karst springs was controlled mainly by climate and human activities, with their contributions being respectively about 60% and 40%. According to the difference of the effect of climate and human activities for each spring, attenuation modes of spring discharge fall into three types: natural process dominated attenuation type, exploitation induced process dominated attenuation type, and mixed attenuation type. The total restored discharge variation of 7 karst springs matched well with the global air temperature change in 1956-2000, clearly indicating the trend of global warming and aridity in the last several decades, and the analysis of discharge variation processes of karst springs can be used as a new tool for global change studies.

Human lymphoblasts were exposed for 6 h to either sodium arsenate (NaAs super(V)), sodium arsenite (NaAs super(III)), monomethylarsonic acid (MMA super(V)), monomethylarsonous acid (MMA super(III)), dimethylarsinic acid (DMA super(V)), or dimethylarsinous acid (DMA super(III)). After exposure slides were prepared, and the mitotic indices (MI) were assessed. We also exposed tubulin directly to each arsenical and spectrophotometrically measured its effect on polymerization. NaAs super(V) caused a small but significant increase in MI. MMA super(V) also caused only a slight increase in MI that just reached statistical significance. In contrast, DMA super(V) caused a significant increase in MI, producing 75% the MI of demecolcine and 4 times the MI of the control. NaAs super(III) had no significant effect on MI and was quite toxic. MMA super(III) induced more than a twofold increase in MI compared to the control, which was about 40% that caused by demecolcine. On a micromolar basis, MMA super(III) was the most potent of the arsenicals tested. DMA super(III) gave inconsistent results. None of the pentavalent arsenicals had a substantial effect (either inhibition or enhancement) on GTP-induced polymerization of tubulin. In contrast, NaAs super(III) inhibited polymerization at concentrations of 1 mM and above and MMA super(III) and DMA super(III) at 10 kM and above. Taken together, these results present a complex picture of how arsenicals may affect cells. These studies demonstrate that the metabolites of arsenic are active not only as chromosome breaking and DNA damaging agents but can also interfere with cell division via tubulin disruption.

AN - 70168942; 16639901 AB - Data on Polybrominated diphenylether (PBDE) concentrations in individual U.S. women were compiled. PBDE levels in adipose tissue, serum, and breast milk from individual U.S. women were found to follow similar lognormal distributions, which exhibited a high degree of variability. The distribution of lipid-normalized PBDE concentrations for all media combined had a median of 47.9 ng/g and a 95th percentile estimate of 302 ng/g. Estimates of congener-specific kinetic parameters were used to calculate the total daily intake of the PBDEs (sum of 5 PBDE prominent congeners, PBDE-47, -99, -100, -153, and -154) that would be required to achieve the measured body burdens. PBDE intake estimates from all routes of exposure were 8.5 ng/kg/d (median) and 54 ng/kg/d (95th percentile). The potential health risks posed by the PBDEs were examined by comparing 95th percentile tissue concentrations in humans (C(human)) to modeled and measured tissue concentrations in rodents that caused no developmental neurotoxicity and reproductive effects (C(rodent)). The ratio of rodent-to-human PBDE concentrations (C(rodent):C(human)) was <1 for alterations of male and female reproductive organs in rats, <10 for neurodevelopmental effects in mice, and <100 for neurodevelopmental effects in rats. If humans are as sensitive as animals to PBDE-induced developmental toxicity, the current margin of safety appears low for a fraction of the population.

AN - 69063142; 16292617 AB - The long-term risks of pesticides to wildlife in the EU currently are assessed by comparing the lowest no-observed-effect concentration (NOEC) determined from the suite of endpoints measured in existing avian and mammalian laboratory reproduction tests with estimated exposure concentrations by calculating Toxicity to Exposure Ratios (TERs). Regulatory authorities experience difficulties when assessing long-term risks because of the lack of accepted methods to improve the ecological realism of exposure and toxicity estimates and understand risks at a population level. This paper describes an approach for interpreting existing avian and mammalian toxicity test data that divides breeding cycles into several discrete phases and identifies specific test endpoints as indicators of direct pesticide effects possible at each phase. Based on the distribution of breeding initiation dates for a species of concern and the dates of pesticide applications, this approach compares the phase-specific toxicity endpoint with the expected pesticide exposure levels during each of the breeding phases. The fate of each breeding attempt is determined through a series of decision points. The cumulative reproductive response of individuals in a breeding population based on this decision framework provides a means of examining the estimated risks over the course of the breeding season and deriving an overall metric of the impact of the pesticide on reproduction. Research needed to further improve the approach is discussed.

AN - 68837087; 16308791 AB - Two different soil amendment processes were evaluated for reducing lead availability from a contaminated soil at a demonstration study site, to reduce potential public health and environmental concerns. A limited variety of in vitro laboratory "availability" tests (relative bioaccessible and environmental mobility) were performed to determine if the available lead in the contaminated soil would be less available after in situ soil amendment (chemical treatment). The relative bioaccessibility results were evaluated in both a short-term period (within 24 h after treatment) and over a long-term time period (quarterly basis for 5 years). Reduction in relative bioaccessibility was noted for one of the treatments immediately after treatment; however, both treatments indicated a significant upward trend in bioaccessibility values over a 5-year time period after treatment. The comparison between the treated units and the control units indicated that the long-term effectiveness of the treatment processes could not be demonstrated.

AN - 68752278; 16263510 AB - Endocrine disruption from environmental contaminants has been linked to a broad spectrum of adverse outcomes. One concern about endocrine-disrupting xenobiotics is the potential for additive or synergistic (i.e., greater-than-additive) effects of mixtures. A short-term dosing model to examine the effects of environmental mixtures on thyroid homeostasis has been developed. Prototypic thyroid-disrupting chemicals (TDCs) such as dioxins, polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers have been shown to alter thyroid hormone homeostasis in this model primarily by up-regulating hepatic catabolism of thyroid hormones via at least two mechanisms. Our present effort tested the hypothesis that a mixture of TDCs will affect serum total thyroxine (T4) concentrations in a dose-additive manner. Young female Long-Evans rats were dosed via gavage with 18 different polyhalogenated aromatic hydrocarbons [2 dioxins, 4 dibenzofurans, and 12 PCBs, including dioxin-like and non-dioxin-like PCBs] for 4 consecutive days. Serum total T4 was measured via radioimmunoassay in samples collected 24 hr after the last dose. Extensive dose-response functions (based on seven to nine doses per chemical) were determined for individual chemicals. A mixture was custom synthesized with the ratio of chemicals based on environmental concentrations. Serial dilutions of this mixture ranged from approximately background levels to 100-fold greater than background human daily intakes. Six serial dilutions of the mixture were tested in the same 4-day assay. Doses of individual chemicals that were associated with a 30% TH decrease from control (ED30), as well as predicted mixture outcomes were calculated using a flexible single-chemical-required method applicable to chemicals with differing dose thresholds and maximum-effect asymptotes. The single-chemical data were modeled without and with the mixture data to determine, respectively, the expected mixture response (the additivity model) and the experimentally observed mixture response (the empirical model). A likelihood-ratio test revealed statistically significant departure from dose additivity. There was no deviation from additivity at the lowest doses of the mixture, but there was a greater-than-additive effect at the three highest mixtures doses. At high doses the additivity model underpredicted the empirical effects by 2- to 3-fold. These are the first results to suggest dose-dependent additivity and synergism in TDCs that may act via different mechanisms in a complex mixture. The results imply that cumulative risk approaches be considered when assessing the risk of exposure to chemical mixtures that contain TDCs.

AN - 68746918; 16127666 AB - Some 2000 species of cyanobacteria (blue-green algae) occur globally in aquatic habitats. They are able to survive under a wide range of environmental conditions and some produce potent toxins. Toxin production is correlated with periods of rapid growth (blooms) and 25%-70% of blooms may be toxic. Anatoxin-a is an alkaloid neurotoxin that acts as a potent neuro-muscular blocking agent at the nicotinic receptor. Acute toxicity, following consumption of contaminated water, is characterized by rapid onset of paralysis, tremors, convulsions and death. Human exposures may occur from recreational water activities and dietary supplements, but are primarily through drinking water. The current studies were conducted to examine the effect of in utero exposure on postnatal viability, growth and neurodevelopment, to evaluate the potential of in vitro embryotoxicity, and to explore the synergistic relationship between anatoxin-a and the algal toxin microcystin-LR by the oral route. The results of preliminary studies on amphibian toxicity are also reported. Time-pregnant mice received 125 or 200 microg kg(-1) anatoxin-a by intraperitoneal injection on gestation days (GD) 8-12 or 13-17. Pup viability and weight were monitored over a 6-day period. Maternal toxicity (decreased motor activity) was observed at 200 microg kg(-1) in both treatment periods. There were no significant treatment-related effects on pup viability or weight on postnatal day (PND) 1 or 6. The GD 13-17 pups were evaluated on PND 6, 12 and 20 for standard markers of neurodevelopmental maturation (righting reflex, negative geotaxis and hanging grip time). No significant postnatal neurotoxicity was observed. In vitro developmental toxicity was evaluated in GD 8 mouse embryos exposed to 0.1-25 microm anatoxin-a for 26-28 h. Perturbations in mouse yolk sac vasculature were noted from the 1.0 microm concentration in the absence of significant embryonic dysmorphology. Potential algal toxin synergism was tested in mice receiving either 0, 500 or 1,000 microg kg(-1) microcystin-LR by gavage and approximately 50 min later receiving either 0, 500, 1,000 or 2,500 microg kg(-1) anatoxin-a by the same route. No deaths occurred at any dose and no definitive signs of intoxication were observed. Stages 17 and 25 toad embryos (Bufo arenarum) were exposed to 0.03-30.0 mg l(-1) of anatoxin-a for 10 days. Adverse effects included a dose-dependent transient narcosis, edema and loss of equilibrium. Most notable was the occurrence of 100% mortality at the high dose in both groups 6-13 days post-exposure. The observed delay between initial exposure and death is highly unusual for anatoxin-a. Published in 2005 by John Wiley & Sons, Ltd.

AN - 68734958; 16252057 AB - Three treatment media, used for the removal of arsenic from drinking water, were sequentially extracted using 10 mM MgCl2(pH 8), 10 mM NaH2PO4(pH 7) followed by 10 mM (NH4)2C2O4(pH 3). The media were extracted using an on-line automated continuous extraction system which allowed the arsenic in each of the extraction fluids to be speciated on-line using IC-ICP-MS. The 10 mM MgCl2 preferentially extracted As(III) from each of the media. The percentage of the arsenic extracted by the MgCl2, relative to a HNO3/H2O2 digestion of the media, ranged from 0.1-2.3% for the three solids. The next sequential extraction fluid, 10 mM NaH2PO4, extracted some of the residual As(III) remaining on each of the media but the predominant species extracted was As(V). The 10 mM NaH2PO4 extracted 15.3 to 42.8% of the total arsenic relative to a total digested concentration for each of the media. The As(III) and As(V) stability studies conducted in these two extraction fluids indicated that conversion between As(III) and As(V) was not significant for the short extraction fluid sample contact time associated with the on-line continuous flow extraction cell. Finally, the 10 mM (NH4)2C2O4 extraction fluid was utilized in an off-line analysis mode because the Fe and As concentrations extracted from the media were not compatible with direct ICP-MS detection. The (NH4)2C2O4 extracted 2.9-29% As(III) for all three media and caused an oxidation of As(III) to As(V) during the extraction period for one of the three media. The sum of the arsenic from each of the three extraction fluids represented 92%, 44% and 53% of the available total arsenic for the three media, respectively. The speciation results for each media were obtained by adding all the speciation results from all three extraction fluids together and the resulting distribution of As(III)/As(V) compared well with the speciation results obtained via XANES.

AN - 68686313; 16224267 AB - Federal and state regulatory agencies that are concerned with issues of environmental management have adopted approaches toward policy-making that are dose- and risk-informed. To that end they (and others) have developed environmental models and computer codes to mimic the transport of contaminants along air, water, food-chain, and related pathways for estimating potential exposures, doses, and risks to individuals, populations, and ecosystems. Their calculations commonly find application in the planning of remediation, and thereafter in the demonstration of compliance with federal and state cleanup standards. As the models and codes have become more sophisticated, so also have requirements on the accuracy and level of detail of the numerical point values and probability distributions of environmental transfer factors and other parameters that serve as input parameters to them. In response to this growing need, the federal Interagency Steering Committee On Radiation Standards (ISCORS) and the Argonne National Laboratory have developed an on-line, national repository of information on parameter values and distributions of known provenance and demonstrated utility. The ISCORS Catalog of References to Parameter Values and Distributions Used in Environmental Pathway Modeling for Cleanup of Sites Contaminated with Radioactivity is a web-based, indexed compilation of references, compendia, databases, and other sources of peer-reviewed information on parameters. It does not itself contain numerical point values or distributions for any particular parameter, but rather it provides links or directions to sites or other published materials where such information can be obtained. Designed to be user-friendly, easily searchable, and readily up-dateable, the Catalog is being filled, after some initial priming, mainly through on-line submissions of proposed references by the Catalog users themselves. The relevant information on a proposed reference is submitted to ISCORS in a simple, standardized format; it is vetted (with acceptance criteria such as publication in a peer-reviewed technical journal, or appearance in a formally-issued federal agency report) and then added semi-automatically to the Catalog. Built around a relational database, the system offers subject- and text-search capabilities, provides information on parameter definitions and methods of measurement, on transport/exposure pathways, and on standard models and codes.

As such, hydrologic tracing is an essential tool that is commonly used to establish flow trajectories, to understand solute-transport processes, and to develop human health and ecological risk assessments. Unfortunately, the use of anthropogenic materials to trace the flow of water may also impart another source of risk to human health and the environment. In general, attempts are usually made to deliberately release tracer agents at concentrations far below their recognized toxic levels. Ecotoxicologically safe levels for injection concentrations of fluorescent tracer agents are generally set at levels far below that which are necessary to maintain measurable downstream concentrations. Appropriate tracer test design is important, because incorrect tracer-mass estimates may result in the release of larger tracer masses than are necessary and that exceed expected environmental concentrations (EECs). To maintain tracer concentrations at or below accepted levels, optimal tracer-test design is essential and may be achieved using the Efficient Hydrologic Tracer-Test Design methodology. By applying an optimal tracer-test design, it is more likely that downstream tracer EECs will be maintained at or below accepted concentrations while maintaining sufficiently high downstream EECs necessary for positive tracer detection.

This study compared the capabilities of two exogenous microbial cultures and an indigenous population to detoxify a Weswood silt loam soil amended with a simple chemical mixture. The first three treatments were unamended soils inoculated with either indigenous microorganisms, Pseudomonas aeruginosa, or Phanerochaete sordida. Three additional treatments consisted of soil amended with benzo[a]pyrene, pentachlorophenol, and 2,4,6-trinitrotoluene, which were inoculated with either indigenous microorganisms, P. aeruginosa, or P. sordida. Samples were collected from the soils at several time points from 0 through 540 or 720 d, sequentially extracted with methylene chloride and methanol, and analyzed for genotoxicity (using the Salmonella/microsome assay) and chemical degradation. Although the indigenous microorganisms were effective for removal of benzo[a]pyrene, the Pseudomonas bacteria exhibited slightly greater removal rates for 2,4,6,-trinitrotoluene. The fungal cultures were significantly more effective at degrading pentachlorophenol. The day 540 extracts from all model chemical-amended treatments were genotoxic. In most cases, the day 540 extracts were more genotoxic than the day 0 extracts. The results suggest that, under appropriate conditions, enriched cultures of microorganisms may have an increased capacity to degrade individual chemicals. However, the products of degradation in some cases might be more genotoxic than the parent compounds.

Single and double hurdle variants of the repeated discrete choice model are developed and applied to choice experiment and multisite seasonal recreation demand data. Our results suggest that hurdle models can generate significant improvements in statistical fit and qualitatively different policy implications, particularly in choice experiment applications where the proper treatment of serial nonparticipation is relatively more ambiguous.

No interference was seen from high levels of background organisms and related, non-target species were detected at approximately 4-5 log sub(10) lower levels of sensitivity than H. pylori by this assay. A standard curve was generated for the method from analyses of filters containing known numbers of added H. pylori cells. Cell numbers on these filters were determined by staining with a species- specific fluorescent antibody and solid phase cytometry analyses. The mean detection sensitivity of the method was 10 H. pylori cells per filter with a 95% confidence sensitivity of 40 cells and a 95% confidence precision interval of +/-0.57 log sub(10) based on duplicate analyses of the samples. One liter drinking water samples from several locations in the US were inoculated with the same H. pylori cell suspensions used to generate the standard curve and gave measurements that were consistent with the standard curve suggesting that these sample matrices produced no interference in the method. This method may be useful for the rapid screening of drinking water for H. pylori.

We used a 1-m beam trawl with attached video camera, continuous global positioning system track overlay, and continuous recording YSI sonde to sample 163 sites in June and July 2002 and 2003. The YSI sonde recorded temperature, salinity, dissolved oxygen, depth, turbidity, and chlorophyll a throughout the tow, while the video camera recorded other habitat characteristics. Habitat patterns at larger spatial scales were assessed with aerial imagery and charted depth data. We caught 25 species and 977 fish, almost twice as many fish being captured in 2002 (596) as in 2003 (381). Winter flounder was the most common species in both years, comprising 60.2% of the catch in 2002 and 33.6% of the catch in 2003. Total fish and winter flounder were three times more abundant in the coastal lagoons than in the bay. We used stepwise multiple regression to develop a general model (all variables, including those affecting catch efficiency) and a habitat model (only habitat variables) describing the relationship between habitat quality and juvenile winter flounder density. The results of the stepwise regression on the general model explained only about 25% of the variability in catch, but they suggested that winter flounder densities were higher at sites in coves and that densities increased with human population density, greater percentages of algal cover, and higher percentages of mud. Densities were negatively correlated with dissolved oxygen and chlorophyll a. In the habitat model (r super(2) = 0.16), densities were higher in coves, at sites with marsh or beach edges, and at sites with human disturbance. Similar to the general model, densities increased with algal cover and decreased with dissolved oxygen. At larger spatial scales, shorelines dominated by beaches and habitat diversity (as calculated by Simpsons diversity index) were positively correlated with higher juvenile winter flounder densities. Overall, the results suggested that juvenile winter flounder were most abundant in coves and upper estuaries. We conclude that these areas may provide beneficial nursery habitat for winter flounder despite apparent human disturbance.

Models that predict the occurrence of stream-fish species based on habitat measures can be useful in management, and predicted probability of occurrence can be a measure of habitat suitability with which to compare alternative habitat management scenarios and assess the effectiveness of stream restoration. We developed such models for each of 13 mid-Atlantic Highlands stream-fish species and species groups by using multiple logistic regression and six instream habitat measures: depth, temperature, substrate, percent riffles, cover, and riparian vegetation. The predictive ability of the models ranged from 61% to 79% in cross-validation and from 38% to 85% on an independent data set. The models predicted well for both the original and test data sets for black bass Micropterus spp., brook trout Salvelinus fontinalis, darters Etheostoma and Percina spp., shiners Notropis spp., and suckers Hypentelium and Moxostoma spp. Suitable habitat for most of the fish species groups was characterized by intermediate depth, a high percentage of cobble and riparian vegetation, and a low percentage of instream cover. The relatively high predictive ability and reasonable responses to habitat measures indicated that these models could be useful for management. However, the models were more sensitive to depth and temperature than to measures that are more commonly affected by restoration activities, such as cover and riparian vegetation.

To identify the particle binding receptor(s) on human AMs, we used functional screening of anti-human AM hybridomas and isolated a mAb, PLK-1, which inhibits AM binding of unopsonized particles (e.g., TiO sub(2), latex beads; 63 plus or minus 5 and 67 plus or minus 4% inhibition, respectively, measured by flow cytometry; n = 11) and unopsonized bacteria ( similar to 84 and 41% inhibition of Escherichia coli and Staphylococcus aureus binding by mAb PLK-1, respectively). The PLK-1 Ag was identified as the human class A scavenger receptor (SR) MARCO (macrophage receptor with collagenous structure) by observing specific immunolabeling of COS cells transfected with human MARCO (but not SR-AI/II) cDNA and by immunoprecipitation by PLK-1 of a protein of appropriate molecular mass ( similar to 70 kDa) from both normal human bronchoalveolar lavage cells (>90% AMs) and human MARCO-transfected COS cells. PLK-1 also specifically inhibited particle binding by COS cells, only after transfection with human MARCO cDNA. Immunostaining showed specific labeling of AMs within human lung tissue, bronchoalveolar lavage samples, as well as macrophages in other sites (e.g., lymph node and liver). Using COS transfectants with different truncated forms of MARCO, allowed epitope mapping for the PLK-1 Ab to MARCO domain V between amino acid residues 420 and 431. A panel of Abs to various SRs identified expression on AMs, but failed to inhibit TiO sub(2) or S. aureus binding. The data support a dominant role for MARCO in the human AM defense against inhaled particles and pathogens.

The chemicals included estradiol (E2), diethylstilbestrol (DES), ethinylestradiol (EE2), estrone (E1), estriol, tamoxifen (TAM), genistein (GEN), p-nonylphenol (PNP), p-tert-octylphenol (PTOP), methoxychlor (MXC), testosterone, and methyltestosterone (MT). Relative binding affinity (RBA) was calculated for each chemical as a function of E2 binding to the receptor. The estrogens DES, EE2, and E1 bound with high affinity to both receptors, with respective RBAs of 583, 166, and 28% (fathead minnow) and 179, 89, and 5% (rainbow trout). Relative binding affinity of E3, TAM, and GEN for both fhmER and rbtER were moderate, with values between 0.3 and 5%. The alkylphenols had weak affinity for the ERs with RBAs for the fhmER of 0.1 and 0.01 for PNP and PTOP, respectively. Corresponding values for the rbtER are 0.027 and 0.009. Estradiol ([ super(3)H]E2) only partially was displaced from both the fhmER and the rbtER by MXC, T, and MT. Comparison of RBAs of the chemicals tested for fhmER and rbtER indicates that the rank order of RBAs essentially are the same for both species.

The direct effects of temperature associated with increased metabolic demand can be exacerbated by other factors, including decreased resistance to disease and increased susceptibility to parasites. We quantified the occurrence of black spot infestation caused by a neascus-type trematode (family Diplostomidae) of juvenile salmonids in Oregons West Fork Smith River stream network during summer 2002 through fall 2003. The highest 7-d average of the daily maximum (ADM) temperatures was positively correlated with infestation rates in both years. We summarized the frequency and infestation severity of juvenile coho salmon Oncorhynchus kisutch by location within the network and summarized temperatures for 19 study reaches. Summer ADMs ranged from approximately 24 not equal to near the watershed mouth to approximately 17 not equal to in the upper reaches, while tributary ADMs ranged from approximately 16-18 not equal to in the lower reaches to 12-17 not equal to in the upper reaches. Temperatures were consistently higher in summer 2003 than in summer 2002. The presence of black spot infestation was more frequently noted in warm main-stem reaches than in adjacent cooler tributary reaches, and infestation rates were generally higher in 2003 than in 2002 in the same reach. Movements of coho salmon juveniles within the stream network also appeared to influence observed infestation rates.

To that end, adult male rats were fed an anticholinesterase insecticide, chlorpyrifos (CPF), for 1 year at three levels of dietary exposure: 0, 1, or 5 mg/kg/day (0+oil, 1+oil, and 5+oil). In addition, half of each of these groups also received a bolus dosage of CPF in corn oil ("spiked" animals; 60 mg/kg initially and 45 mg/kg thereafter) every 2 months (0+CPF, 1+CPF, 5+CPF). Animals were analyzed after 6 or 12 months of dosing, and again 3 months after cessation of dosing (i.e., "recovery" animals-six experimental groups with n = 4-6/group/time point). Cholinesterase (ChE) activity was measured in retina, whole blood, plasma, red blood cells, diaphragm, and brain [pons, striatum, and the rest of the brain (referred to simply as "brain")]. Muscarinic receptor density was assessed in retina, pons, and brain, whereas dopamine transporter density and the levels of dopamine and its metabolites were assessed in striatum. Cholinesterase activity at 6 and 12 months was not different in any of the tissues, indicating that a steady state had been reached prior to 6 months. The 1+oil group animals showed ChE inhibition only in the blood, whereas the 5+oil group exhibited greater than or equal to 50% ChE inhibition in all tissues tested. One day after the bolus dose, all three groups (0+CPF, 1+CPF, 5+CPF) showed greater than or equal to 70% ChE inhibition in all tissues. Muscarinic receptor density decreased only in the brain of the 5+oil and 5+CPF groups, whereas dopamine transporter density increased only at 6 months in all three spiked groups. Striatal dopamine or dopamine metabolite levels did not change at any time. Three months after CPF dosing ended, all end points had returned to control levels. These data indicate that, although chronic feeding with or without intermittent spiked dosages with CPF produces substantial biochemical changes in a dose- and tissue-related manner, there are no persistent biochemical changes.

The majority of surfacewater SVs were primarily derived for the protection of aquatic organisms using 2 approaches: (1) a statistical assessment of toxicity values by species groupings, such as "ambient water quality criteria," or (2) extrapolation of a lowest observed adverse effect level determined from limited toxicity data using an uncertainty factor. Sediment SVs were primarily derived for the protection of benthic invertebrates using 2 approaches: (1) statistical interpretations of databases on the incidence of biological effects and chemical concentrations in sediment, or (2) values derived from equilibrium partitioning based on a surfacewater SV. Soil SVs were derived using a diversity of approaches and were usually based on the lowest value determined from soil toxicity to terrestrial plants or invertebrates and, less frequently, from modeled, incidental soil ingestion or chemical accumulation in terrestrial organisms. The various SV compilations and methodologies had varying levels of conservatism and were not consistent in the pathways and receptors considered in the SV derivation. Many SVs were derived from other compilations and were based on outdated values, or they relied on only older toxicity data. Risk assessors involved in ERA should carefully evaluate the technical basis of SVs and consider the uncertainty in any value used to determine the presence or absence of risk and the need for further assessment.

Due to their wide use in commercial products and their persistent nature, long-term exposure to PBDEs may pose a human health risk, especially to children. Our previous reports showed that the commercial PBDE mixture, DE-71, affected protein kinase C (PKC) and calcium homeostasis in a similar way to those of a structurally-related polychlorinated biphenyl (PCB) mixture. These intracellular signaling events are associated with neuronal development and learning and memory function. The objectives of the present study were to test whether environmentally relevant PBDE congeners, with different position and number of bromines, affected PKC translocation in cerebellar granule neuronal cultures and compare the potency and efficacy of PBDE congeners with their super(14)C-accumulation. All the tested PBDE congeners increased super(3)H-phorbol ester (PDBu) binding, and a significant effect was seen as low as 10 mu M. Among the congeners tested, 2,2',4,4'-tetrabromodiphenyl ether (PBDE 47) increased super(3)H-PDBu binding in a concentration-dependent manner and to a greater extent than other congeners. These effects were seen at concentrations and exposure times where no cytotoxicity was observed. The efficacy of PBDE congeners varied with their structural composition, and the effects seen on super(3)H-PDBu binding with some PBDE congeners are similar to those of PCB congeners. Cerebellar granule neurons accumulated all three PBDE congeners (PBDEs 47, 99, and 153) following exposure. At the lowest concentration (0.67 mu M), about 13-18% of the total dose of super(14)C-PBDE congeners was accumulated by these neurons. There were distinct differences in the pattern of super(14)C-PBDE accumulation among the PBDE congeners. The super(14)C-PBDE accumulation, either represented as percent basis or nanomole basis, was much lower for the 30.69 mu M PBDE 99 and 10.69-30.69 mu M PBDE 153 than at the lower concentrations, which may be due to low solubility of these congeners. The accumulation pattern with PBDE 47 did not vary with concentration. On a nanomole accumulation basis, PBDEs 47, 99, and 153 accumulation was linear with time. While the nanomole accumulation was linear with concentration for PBDE 47, it is nonlinear for PBDEs 99 and 153. The pattern of PBDE accumulation seems to correlate with the effects on PKC translocation, with regression values of 0.773-0.991. These results indicate that PBDEs affected PKC translocation in neurons in a similar way to those of other organohalogens, some PBDE congeners are equally efficacious as the respective PCB congeners, and PBDE accumulation correlated well with PKC translocation, suggesting a common mode of action for this group of chemicals.

Nutrient criteria have been established based on ecoregional differences, recognizing that geographic variation in climate, topography, geology, and land use require use of different criteria values for different regions of the continental United States. Several studies have demonstrated that land-cover composition also strongly influences nutrient concentrations and yields. We examined the relative importance of ecoregions and watershed land-cover composition in explaining variability in nitrogen (N) and phosphorus (P) concentrations by re-analyzing the National Eutrophication Survey (NES) data reported by Omernik (1977). The variance of N concentrations among land-cover composition classes within ecoregions was six times larger than the variance among ecoregions. For P concentrations, land-cover composition within ecoregions accounted for three times more variance than ecoregions themselves. Variance across ecoregions was only weakly significant after accounting for variance in land-cover composition within ecoregions. The results suggest that the relationship between land-cover composition and nutrient concentrations in aquatic systems should also be used to help guide establishment of nutrient criteria.

However in recent years, these methods have come under scrutiny due to technical and unforeseen error issues. In this study, we analyzed 18 soil samples via X-ray diffraction (XRD), selective sequential extraction (SSE), and a physiologically based extraction test (PBET). The data were compared against each other and to previous data collected for the soil samples employing X-ray absorption fine structure spectroscopy coupled with linear combination fitting (XAFS-LCF), which spectroscopically speciates and quantifies the major Pb species in the samples. It was observed that XRD was incapable of detecting pyromorphite, the hopeful endpoint of the immobilization strategy for reduced Pb bioavailability in our studies. Further, the SSE and PBET extraction methods demonstrated an increase of recalcitrant Pb forms in comparison to the XAFS-LCF results suggesting that SSE and PBET methods induced the precipitation of pyromorphite during the extraction procedures. The theme of this paper illustrates the experimental concerns of several commonly employed methods to investigate immobilization strategies of amended, metal-contaminated systems which may not be in true equilibrium. We conclude that appropriate application of spectroscopic methods provides more conclusive and accurate results in environmental systems (i.e., Pb, Zn, Cd, etc.) examining P-induced immobilization.

In 2000 we conducted six 1-day exposure studies where spontaneously hypertensive (SH) rats were exposed to filtered air or CAPs ( less than or equal to 2.5 mu m, 1,138-1,765 mu m super(3)) for 4 hr (analyzed 1-3 hr afterward). In seven 2-day exposure studies in 2001, SH and Wistar Kyoto (WKY) rats were exposed to filtered air or CAP ( less than or equal to 2.5 mu m, 144-2, 758 mu m super(3)) for 4 hr/day X 2 days (analyzed 1 day afterward). Despite consistent and high CAP concentrations in the 1-day exposure studies, no biologic effects were noted. The exposure concentrations varied among the seven 2-day exposure studies. Except in the first study when CAP concentration was highest, lavageable total cells and macrophages decreased and neutrophils increased in WKY rats. SH rats demonstrated a consistent increase of lavage fluid gamma -glutamyl-transferase activity and plasma fibrinogen. Inspiratory and expiratory times increased in SH but not in WKY rats. Significant correlations were found between CAP mass (microgram per cubic meter) and sulfate, organic carbon, or zinc. No biologic effects correlated with CAP mass. Despite low chamber mass in the last six of seven 2-day exposure studies, the levels of zinc, copper, and aluminum were enriched severalfold, and organic carbon was increased to some extent when expressed per milligram of CAP. Biologic effects were evident in those six studies. These studies demonstrate a pattern of rat strain-specific pulmonary and systemic effects that are not linked to high mass but appear to be dependent on CAP chemical composition.

The first was triggered by the Bhopal tragedy in 1984, which led to major changes within the US chemical industry and a series of Federal laws and regulations intended to prevent major chemical accidents. A more recent transformation is currently underway in the wake of the 9/11 attacks on New York and Washington. It involves the advent of various security-related requirements affecting many of the same facilities covered under the existing accident prevention rules. This paper provides an overview of these transformations and their impacts.

AN - 68613728; 16176916 AB - Human milk is a unique biological matrix that can be used to estimate exposures in both the mother and the breastfed infant. In addition, the presence of environmental chemicals in human milk may act as a sentinel for exposures to a broader population. Several factors play a role in determining the quantity of chemicals transferred to milk and, subsequently, to the breastfeeding infant, including maternal, infant, and chemical characteristics. Exposure to certain environmental chemicals during critical periods can disrupt normal infant development, yet few data exist to quantify the hazards posed by environmental chemicals in human milk. Chemicals measured in human milk may also provide insights to agents suspect in altering breast development and breast-related disease risk. Carefully designed exposure assessment and toxicokinetic studies are needed to elucidate mechanisms and establish relationships between human milk and other biologic matrices. Data from human milk biomonitoring studies can be used to inform and validate models that integrate information about chemical properties, human metabolism, and biomarker concentrations. Additional research is needed to determine the degree to which environmental chemicals enter, are present in, and are excreted from human milk, their impact on the host (mother), and the extent of their bioavailability to breastfeeding infants.

This study compared the disposition of MMA(V) and MMA(III) in adult female B6C3F1 mice. Mice were gavaged po with MMA(V), either unlabeled or labeled with super(1) super(4)C at two dose levels (0.4 or 40 mg As/kg). Other mice were dosed po with unlabeled MMA(III) at one dose level (0.4 mg As/kg). Mice were housed in metabolism cages for collection of excreta and sacrificed serially over 24 h for collection of tissues. MMA(V)-derived radioactivity was rapidly absorbed, distributed and excreted. By 8 h post-exposure, 80% of both doses of MMA(V) were eliminated in urine and feces. Absorption of MMA(V) was dose dependent; that is, there was less than a 100-fold difference between the two dose levels in the area under the curves for the concentration-time profiles of arsenic in blood and major organs. In addition, urinary excretion of MMA(V)-derived radioactivity in the low dose group was significantly greater (P < 0.05) than in the high dose group. Conversely, fecal excretion of MMA(V)-derived radioactivity was significantly greater (P < 0.05) in the high dose group than in the low dose group. Speciation of arsenic by hydride generation-atomic absorption spectrometry in urine and tissues of mice administered MMA(V) or MMA(III) found that methylation of MMA(V) was limited while the methylation of MMA(III) was extensive. Less than 10% of the dose excreted in urine of MMA(V)-treated mice was in the form of methylated products, whereas it was greater than 90% for MMA(III)-treated mice. In MMA(V)-treated mice, 25% or less of the tissue arsenic was in the form of dimethylarsenic, whereas in MMA(III)-treated mice, 75% or more of the tissue arsenic was in the form of dimethylarsenic. Based on urinary analysis, administered dose of MMA(V) did not affect the level of its metabolites excreted. In the tested range, dose affects the absorption, distribution and route of excretion of MMA(V) but not its metabolism.

a new archive of surface processes AN - 868009444; 2011-046076 AB - The deep-sea gorgonian coral Primnoa spp. live in the Atlantic and Pacific Oceans at depths of 65 to 3200 m. They have an arborescent growth form with a skeletal axis composed of annual rings made from calcite and gorgonin. Lifespans may exceed several hundreds of years. It has been suggested that isotope profiles from the gorgonin fraction of the skeleton could be used to reconstruct long-term, annual-scale variations in surface productivity. We tested assumptions about the trophic level, intra- and inter-colony isotopic reproducibility, and preservation of isotopic signatures in a suite of modern and fossil specimens. Measurements of gorgonin delta (super 15) N indicate that Primnoa spp. feed mainly on zooplankton and/or sinking particulate organic matter (POM (sub sink) ), and not on suspended POM (POM (sub susp) ) or dissolved organic carbon (DOC). Gorgonin delta (super 13) C and delta (super 15) N in specimens from NE Pacific shelf waters, NW Atlantic slope waters, the Sea of Japan, and a South Pacific (Southern Ocean sector) seamount were strongly correlated with surface apparent oxygen utilization (AOU; the best available measure of surface productivity), demonstrating coupling between skeletal isotopic ratios and biophysical processes in surface water. Time-series isotopic profiles from different sections along the same colony, and different colonies inhabiting the same area were identical for delta (super 13) C, while delta (super 15) N profiles were less reproducible. Similarity in C:N, delta (super 13) C and delta (super 15) N between modern and fossil specimens suggest that isotopic signatures are preserved over millennial timescales. These results support the use of Primnoa spp. as historical recorders of surface water processes such as biological productivity and the isotopic composition of source nutrients. JF - Marine Ecology.

AN - 69070660; 16417039 AB - Vinclozolin is a fungicide that has been shown to cause Leydig cell tumors and atrophy of the accessory sex glands in adult rodents. In addition, exposure of rats during pregnancy causes a pattern of malformations in the male urogenital tract. A wealth of standard toxicological studies and targeted research efforts is available related to this adverse effect, and these were used to evaluate the Human Relevance Framework (HRF) for noncancer health effects. Vinclozolin and two of its metabolites, designated M1 and M2, have been shown to bind and inhibit the function of the rat and human androgen receptor. Other means of interfering with androgen receptor function (e.g., by exposure to the pharmaceutical agent flutamide) lead to similar adverse health outcomes. There is direct in vivo evidence in the rat prostate that androgen-dependent gene expression changes occur after exposure to vinclozolin. There are no proposed alternatives to the androgen receptor-mediated mode of action. Based on what is known about kinetic and dynamic factors, confidence is high that the animal mode of action (MOA) for vinclozolin-induced malformation of the male reproductive tract is highly plausible in humans.

AN - 69070560; 16422347 AB - Most toxicological and pharmacological studies are performed in laboratory animals maintained under comfortable environmental conditions. Yet, the exposure to environmental toxicants as well as many drugs can occur under stressful environmental conditions during rest or while exercising. The intake and biological efficacy of many toxicants is exacerbated by exposure to heat stress, which can occur in several ways. The increase in pulmonary ventilation during exposure to hot environments results in an increase in the uptake of airborne toxicants. Furthermore, the transcutaneous absorption of pesticides on the skin as well as drugs delivered by skin patches is increased during heat stress because of the combined elevation in skin blood flow coupled with moist skin from sweat. The thermoregulatory response to toxicant exposure, such as hypothermia in relatively small rodents and fever in humans, also modulates the physiological response to most chemical agents. This paper endeavors to review the issue of environmental heat stress and exercise and how they influence thermoregulatory and related pathophysiological responses to environmental toxicants, as well as exposure to drugs.

AN - 69070323; 16417034 AB - It has been known for decades that mutagenicity plays an important role in the activity of most carcinogens. This mutagenicity can result from direct damage to DNA through a chemical being DNA reactive or from indirect effects, such as through the production of oxygen radicals that then react with DNA. This article presents a set of key events whereby DNA reactivity initiates the process of carcinogenicity that leads to the subsequent mutation induction and enhanced cell proliferation that ultimately results in tumor development. This set of key events for DNA-reactive chemicals was applied to two case studies (aflatoxin B1 and dichloromethane) with the aim of assessing the utility of the Human Relevance Framework (HRF) for this class of chemicals. The conclusions were that the HRF was a viable approach for the use of mechanistic data for DNA-reactive chemicals obtained from both laboratory animals and human cells in vivo and in vitro for predicting human carcinogenicity. In the case of aflatoxin B1, the HRF could be used to predict that carcinogenicity in humans was a likely outcome. In contrast, the HRF predicted that the human carcinogenic potential of dichloromethane was at best less likely than in rodents; this conclusion was supported by the available epidemiological data.

AN - 69069751; 16417043 AB - An increasing incorporation of mode of action (MOA) information into risk assessments has led to examination of animal MOAs to determine relevance to humans. We examined a specific MOA for developmental neurotoxicity using the MOA/Human Relevance Framework (Meek et al., 2003). The postulated MOA of ototoxicity in rats involves early postnatal exposure to polychlorinated biphenyls (PCBs) via lactation, an upregulation of hepatic uridine diphosphoglucuronyltransferases (UGTs), and subsequent hypothyroxinemia during a critical period of cochlear development, with the ultimate neurotoxic consequence of hearing loss. This review concludes with high confidence in the animal MOA and medium confidence for the interspecies concordance for the key events in the MOA. Possible interspecies differences in toxicodynamic factors moderate confidence in some key events. In addition, there is a question of whether ambient human exposures are large enough to cause human fetal hypothyroxinemia to the degree needed to cause hearing loss. Data gaps identified by this analysis include a need to characterize the induciblity of human fetal UGTs and the comparative sensitivity of UGT induction by xenobiotics in rats and humans. Research on these areas of uncertainty will increase confidence that this MOA for PCBs is not likely to not occur in humans, assuming normal conditions of limited ambient exposure.

AN - 69069706; 16417040 AB - Valproic acid (VPA) has long been known to cause spina bifida, a neural tube defect, and other effects in fetuses of women treated with this drug. Toxicological tests in laboratory mice and rats at human therapeutic doses also show neural tube and other defects. Studies show that VPA alters Wnt signaling in human and animal cells, inducing Wnt-dependent gene expression at doses that cause developmental effects. Structural analogues of VPA that do not have this effect on Wnt signaling do not cause developmental effects. Similarly, Trichostatin A, a compound that mimics VPA in its effects on Wnt gene expression, also causes similar developmental effects. Alteration of Wnt signaling is empirically well supported as the postulated mode of action (MOA) for VPA's developmental effects in animals. VPA causes alteration of Wnt signaling in both human and animal cells systems at the same dose levels. The correspondence of effects on signaling and of effects on development in animals and humans supports the view that alteration of Wnt signaling is a relevant MOA in humans.

AN - 68741205; 16249997 AB - Perfluorooctane sulfonate (PFOS), found widely in wildlife and humans, is environmentally and metabolically stable. Environmental PFOS may be from its use as a surfactant, hydrolysis of perfluorooctanesulfonyl fluoride, and degradation of N-alkyl-perfluorooctanesulfonamide compounds formerly used in numerous applications. Prenatal exposure to PFOS in rodents causes neonatal mortality; treatment on gestation days (GD) 19-20 is sufficient to induce neonatal death in rats. Affected pups are born alive but present with labored breathing. Their lungs are pale and often do not expand fully on perfusion. Pregnant Sprague-Dawley rats received 0, 25, or 50 mg/kg/day PFOS/K+ orally on GD 19-20. Lungs from GD 21 fetuses and neonates were prepared for histology and morphometry. Rescue experiments included co-administration of dexamethasone or retinyl palmitate with PFOS. Pulmonary surfactant was investigated with mass spectrometry in GD 21 amniotic fluid and neonatal lungs. Microarray analysis was carried out on PND 0 lungs. Histologically, alveolar walls were thicker in lungs of PFOS-exposed newborns compared to controls. The ratio of solid tissue:small airway was increased, suggesting immaturity. Rescue studies were ineffective. Phospholipid concentrations and molecular speciation were unaffected by PFOS. No changes in markers of alveolar differentiation were detected by microarray analysis. Morphometric changes in lungs of PFOS exposed neonates were suggestive of immaturity, but the failure of rescue agents and normal pulmonary surfactant profile indicate that the labored respiration and mortality observed in PFOS-treated neonates was not due to lung immaturity.

AN - 68726696; 16245848 AB - Granular activated carbon is a frequently explored technology for removing synthetic organic contaminants from drinking water sources. The success of this technology relies on a number of factors based not only on the adsorptive properties of the contaminant but also on properties of the water itself, notably the presence of substances in the water which compete for adsorption sites. Because it is impractical to perform field-scale evaluations for all possible contaminants, the pore surface diffusion model (PSDM) has been developed and used to predict activated carbon column performance using single-solute isotherm data as inputs. Many assumptions are built into this model to account for kinetics of adsorption and competition for adsorption sites. This work further evaluates and expands this model, through the use of quantitative structure-property relationships (QSPRs) to predict the effect of natural organic matter fouling on activated carbon adsorption of specific contaminants. The QSPRs developed are based on a combination of calculated topographical indices and quantum chemical parameters. The QSPRs were evaluated in terms of their statistical predictive ability,the physical significance of the descriptors, and by comparison with field data. The QSPR-enhanced PSDM was judged to give results better than what could previously be obtained.

AN - 68660847; 16203257 AB - This mini-monograph was developed to highlight the experiences of the National Institute of Environmental Health Sciences (NIEHS)/U.S. Environmental Protection Agency (EPA) Centers for Children's Environmental Health and Disease Prevention Research, focusing particularly on several areas of interest for the National Children's Study. These include general methodologic issues for conducting longitudinal birth cohort studies and community-based participatory research and for measuring air pollution exposures, pesticide exposures, asthma, and neurobehavioral toxicity. Rather than a detailed description of the studies in each of the centers, this series of articles is intended to provide information on the practicalities of conducting such intensive studies and the lessons learned. This explication of lessons learned provides an outstanding opportunity for the planners of the National Children's Study to draw on past experiences that provide information on what has and has not worked when studying diverse multiracial and multiethnic groups of children with unique urban and rural exposures. The Children's Centers have addressed and overcome many hurdles in their efforts to understand the link between environmental exposures and health outcomes as well as interactions between exposures and a variety of social and cultural factors. Some of the major lessons learned include the critical importance of long-term studies for assessing the full range of developmental consequences of environmental exposures, recognition of the unique challenges presented at different life stages for both outcome and exposure measurement, and the importance of ethical issues that must be dealt with in a changing medical and legal environment.

Passing well to the west of Dauphin Island, the storm still impacted the island with wind speeds up to 129 km/hr (a Category 1 hurricane on the Saffir-Simpson scale). This resulted in substantial changes along the island's gulf side. The eastern end of the island experienced a storm surge along with accompanying storm waves that easily overtopped the swash zone berm crest. Storm waves washed tens of meters landward and flattened the beach profile. Much of the western end of the island was completely overwashed by storm waves. As of early 2005, natural shoreline processes have not restored the pre-storm beach profile or returned the swash zone to its former position. Tropical storms and hurricanes that impact the island reveal its vulnerability and dependence on regular sand nourishment. Hurricane Georges exposed the fragile nature and precarious setting of Dauphin Island in the Gulf of Mexico.

Corresponding ground waters have been noted for elevated arsenic as well (up to 1000's ppb), and very high arsenic had been observed at points of ground water discharge into the surface water systems. The role of anthropogenic land use factors and the status of natural arsenic conditions are often confusing in regards to the arsenic sources and pathways of the contaminants. In this presentation we provide data on arsenic and its proxy correlations with Ni, Co, and Zn, as well as Fe. An earlier study of 169 soil samples analyzed for As, Ni, and Fe (from a small area of approximately 3 X 3 miles) reveals Ni-As, and Ni-Fe correlations (R (super 2) = 0.666 and 0.795, respectively) suggesting a similar source despite different speciations of Ni and As in soils. The likely source mineral is cobaltite (CoAsS) identified by a microprobe analysis in several fresh bedrock samples from a drill core. Co (19 to 24 wt%) is partially substituted by Ni (5.5 to 6.6 wt%) while arsenic (43 to 44wt%) is near stoichiometric. No significant amounts of Co or As were detected in pyrites. Average Ni content in pyrites is 0.36 wt%. Studies of arsenic contaminated ground water within the same region have shown that arsenic in ground water is due to redox potential change from the oxidizing to reducing conditions. Arsenic absorbed on hydrous ferric oxide (HFO) coatings in soils is liberated by a reductive dissolution of the HFO substrates. A reverse process is observed when arsenic contaminated GW is discharged into an oxidizing surface water environment. Pond bottom sediments at contaminated GW discharge points have elevated arsenic that also correlates with Ni, Co, and Zn. Correlations of As with Fe, Ni, Co, and Zn yield statistically significant correlation coefficients for pond bottom sediments in areas not affected by anthropogenic past activities (R (super 2) = 0.849, 0.873, 0.909, 0.881, respectively). Past tannery disposals interfere with these patterns by superimposition of different trace metal patterns. Landfill leachates create highly reducing environments leading to sulfide precipitations in the affected soils and drop in the levels of Ni, Co, and Zn in the discharging ground water.

A small inlet is known as Red Cove, due to the ubiquitous red staining on the pond-bottom sediments. Iron (as iron oxyhydroxides) reaches percent levels in sediment, but arsenic is also present at concentrations up to several thousand mg/kg. Despite numerous environmental investigations, a clear understanding of the nature and extent of contamination in Red Cove, as well as the governing fate and transport mechanisms, has remained elusive. We present a preliminary unified conceptual model for arsenic fate and transport at Red Cove, which considers ground water flow; chemistry of ground water, surface water, sediment and sediment pore-water; and sediment toxicity. Arsenic is naturally occurring in local soils and bedrock and is associated with iron in oxide and sulfide minerals. Previous work (Stein, et al., 2004) indicates that ground water oxidation-reduction potential (ORP) exerts considerable control on arsenic mobility, primarily through 1) precipitation of hydrous ferric oxides (HFO) and sorption of arsenic, 2) reductive dissolution of HFO and arsenic release, and 3) formation of iron and/or arsenic sulfide phases. Low ORP in the vicinity of SHL gives rise to elevated dissolved iron and arsenic concentrations. Ground water flow data from monitoring wells indicate consistent head-field gradients focused toward Red Cove. Reducing ground water, discharging to the cove from the direction of the landfill, encounters a redox boundary below the sediment-water interface, where arsenic is precipitated along with HFO and possibly sulfides in the sediments. However, arsenic is generally nondetect in surface water. A redox interface was observed at several locations at or near the cove at 1 to 2 m below the sediment surface. Preliminary estimates suggest that several Kg of arsenic are transported to Red Cove annually by these processes, and toxicity data indicate impairment. Remedial measures, if needed, must consider the geochemical and hydrologic dynamics of ground water-surface water interactions.

The LUB GWMA, primarily a semi-arid climate agricultural area, has been previously managed for regional elevated nitrate levels in groundwater related to commercial irrigation, farming, and food processing industries. Perchlorate was originally detected in regional groundwater resources in 2003 as part of the concurrent groundwater nitrate investigations. A number of well types were tested including monitoring, domestic, irrigation, industrial, community, and stock watering wells, with perchlorate concentrations ranging from 1 ug/l to 24.8 ug/l in groundwater. The frequency of occurrence based on major well types for monitoring, domestic, and irrigation wells were 59%, 46%, and 75%, respectively, from a total of 135 wells tested. A number different land uses within the LUB GWMA may potentially contribute to perchlorate occurrence, including two Department of Defense munitions sites, a formerly used defense site (FUDS), a commercial aerospace rocket motor engine test facility, and agricultural application of Chilean nitrate fertilizers. Collectively, however, these potential sources do not account for the complete range of occurrence of perchlorate in the LUB GWMA, and a naturally occurring component may exist. The current hypothesized Conceptual Site Model (CSM) for regional groundwater perchlorate occurrence is facilitated transport of irrigation recharge in areas that may exhibit salt build-up due to evapotransporation in excess of precipitation. This is supported by a general correlation of total dissolved ions concentrations to perchlorate concentrations in groundwater. Due to the use of groundwater resources for crop irrigation, stock watering for dairy cattle, and food processing industries, further investigations of other exposure pathways are also planned.

One stream originates at a headcut spring and is protected from surface runoff by a man-made berm. Flow is contributed almost entirely by ground water emerging from the headcut spring and ground water flux through the streambed. The adjacent stream (14m away at headcut) is not protected by a berm and does not have a flowing spring at its headwaters. It is open to surface runoff and input of soil and organic matter from the upgradient pasture and fields. Both streams are shallow, narrow, and slow. The two streams combine at a confluence 57m downstream in the protected, spring-fed stream and 70m downstream in the runoff stream. Several sampling stations have been established in both streams and downstream of their confluence. Since September 2003, samples have been collected every 4-6 weeks and are being analyzed for several parameters, including temperature; pH; conductivity; alkalinity; NO3-; NO2-; total N; total dissolved N; NH4+; urea; Fe (II, III and total); total organic C; and the dissolved gases O2, N2O, CH4, CO2 and H2. NO3--N concentrations decrease along both streams from headcut to confluence--from 7-12 to 0.2-1.5mg/L in the runoff channel and from 6-8 to 3-5mg/L in the spring-fed channel. Discharge and concentration measurements show that dilution by ground water flux does not account for all of the nitrate loss. Tracer experiments within the spring-fed stream show lower percent recovery for NO3- than Br- --an indication that denitrification may be occurring. Ammonia, alkalinity, TOC and NO2- are consistently higher in the runoff stream than in the spring-fed stream, but trends along each flow path are sometimes weak and seem to vary with season. Fe2+ is usually, but not always, more concentrated than Fe3+ at each station, especially in the runoff stream. Thus, the adjacent streams have different distributions of certain dissolved chemical species in a setting where climate, relief, land use and underlying geology are the same.

A biotic ligand model (BLM) and a pore water-sediment partitioning model are used to predict the sediment concentration that is in equilibrium with the biotic ligand effects concentration. This initial application considers only partitioning to sediment particulate organic carbon. This procedure bypasses the need to compute the details of the pore-water chemistry. Remarkably, the median lethal concentration on a sediment organic carbon (OC)-normalized basis, SEM (super *) (sub x,OC) , is essentially unchanged over a wide range of concentrations of pore-water hardness, salinity, dissolved organic carbon, and any other complexing or competing ligands. Only the pore-water pH is important. Both acute and chronic exposures in fresh- and saltwater sediments are compared to predictions for cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb), and zinc (Zn) based on the Daphnia magna BLM. The SEM (super *) (sub x,OC) concentrations are similar for all the metals except cadmium. For pH = 8, the approximate values (mu mol/gOC) are Cd-SEM (super ) (sub x,OC) congruent to 100, Cu-SEM (super *) (sub x,OC) congruent to 900, Ni-SEM (super *) (sub x,OC) congruent to 1,100, Zn-SEM (super *) (sub x,OC) congruent to 1,400, and Pb-SEM (super *) (sub x,OC) congruent to 2,700. This similarity is the explanation for an empirically observed dose-response relationship between SEM and acute and chronic effects concentrations that had been observed previously. This initial application clearly demonstrates that BLMs can be used to predict toxic sediment concentrations without modeling the pore-water chemistry.

The site is a former solid rocket propellant manufacturing facility that operated from 1959 through 2004. The site occupies 5,200 acres, with operations primarily situated in alluvium deposited within broad stream valleys. The confluence of several small streams occurs at the downgradient property boundary at a creek which then flows into a drinking water reservoir for a nearby city. Several distinct plumes of perchlorate are present in groundwater at the site. Perchlorate, an inorganic chemical compound consisting of chlorine bonded to four oxygen atoms (ClO (sub 4) (super -) ), can interfere with iodide uptake by the thyroid gland and may result in decreased thyroid hormone production. Concentrations of perchlorate have been measured in groundwater at the site exceeding 800,000 micrograms per liter (mu g/l). Perchlorate is migrating to surface water by hydraulic connection with groundwater and from runoff over contaminated surface soils during storm events. The primary health concern is the potential for a nearby drinking water reservoir to be impacted by perchlorate migrating through surface streams. However, perchlorate has never been detected in the reservoir, and off-site surface water samples rarely exceed 3 mu g/l. Most of the on-site streams are intermittent, with ninety percent of the annual runoff occurring November to April. Monthly surface water monitoring conducted since 1998 at designated creek stations has frequently detected the presence of low concentrations of perchlorate during winter months. A recent change in sampling methodology, in which individual flow-proportioned samples were collected during storm events, resulted in the detection of much higher perchlorate concentrations, including the highest recorded off-site surface water concentration (61 mu g/l). However, the storm sampling demonstrated that perchlorate loading in streams is generally of short duration, and overall, it appears that very little perchlorate mass is delivered to the reservoir.

Hydrologic models are usually impractical in modeling the flowpaths because of difficulties in parameterizing the mountain catchments with complex terrains and highly fractured bedrocks. Here we report on innovative use of isotopic and geochemical tracers in understanding flowpaths in a draining tunnel of mine working waters in Leadville, CO and in natural streams in Valles Caldera, NW. Understanding flowpaths and source waters in Leadville is problematic because of the occurrence of thousands of mine shafts, stopes, and adits. In Leadville, mixing spaces were determined by the eigenvectors of Principal Component Analysis (PCA) based on compositions of 11 isotopic and geochemical tracers in the tunnel outflow. O-18 and tritium were used as benchmarks to determine the number of end-members and conservative geochemical tracers. Two mixing spaces were determined to be appropriate for O-18 and tritium, indicating that three end-members contribute to the tunnel outflow. Geochemical tracers, Ca (super 2+) , Mg (super 2+) , Na (super +) , K (super +) , Si, ANC and conductance, behaved similarly as isotopes and thus believed to be conservative. Three end-members contributing to the tunnel outflow were finally identified and quantified by all conservative tracers using end-member mixing analysis (EMMA): mine pool water (42%), shallow groundwater (35%) and deep groundwater (23%); individual contributions varied seasonally. The selected end-members and their contributions were validated by predicting isotopic and chemical compositions in the tunnel outflow using the EMMA results. Source waters and flowpaths from Valles Caldera will also be presented following the same procedure.

Stream incision is a major threat to these meadow ecosystems and a multidisciplinary research team is developing technical guidance and decision support tools to assist resource managers with maintaining and restoring this valuable habitat. Field work proposed as part of the EPA/Forest Service project included collecting cores to describe stratigraphic units for geomorphic and hydrogeologic interpretations, probing to bedrock to ground truth geophysical investigations of bedrock structure and thickness of valley-fill sediments, and installing monitoring wells for evaluating hydraulic heads and ground-water flow patterns and for collecting water quality samples. However, accomplishing these tasks with minimal disturbance to the fragile riparian meadow systems was a concern to local resource managers. An innovative exploration unit, designed by EPA personnel in conjunction with equipment manufacturers, was used to successfully complete the field activities. The rig consists of a GeoProbe (super TM) 540MTX direct-push tool mounted on a modified HydroTraxx TJ645 vehicle. The rig was designed specifically for use in conditions such as those encountered in the upland riparian meadows: saturated soils, steep slopes, and entrenched stream channels. The rig does flatten vegetation temporarily, but the path of the equipment was unnoticeable after the subsequent growing season. The unit was able to collect continuous cores to a depth of 12 m and interval specific core samples to a depth of 25 m. The rig also was able to advance a probe to almost 30 m to evaluate depth to bedrock (refusal). Monitoring wells were constructed to depths of 12 m in unconsolidated material ranging from fine-grained organic soils to poorly-sorted alluvial fan deposits. These data, unobtainable until now, are being used to support development of management and restoration strategies for Great Basin upland riparian meadow systems.

The PRB has three zones consisting of (from upgradient): 2 ft of gravel/ZVI mixture, 4 ft of ZVI, and 2 ft of gravel. Ground water samples and water level data have been collected at regular intervals from more than 50 wells in the PRB. Satisfactory performance of the PRB requires that contaminant concentrations are lowered to regulated levels, a high proportion of the ambient ground water flow is treated and, there are no adverse affect to land use. Contaminant concentrations remain low in most wells in the ZVI zone to satisfy the first criterion. Attainment of the second and third criteria is less certain however considering a continuously rising ground water mound behind the PRB. This occurrence is likely coupled to an order of magnitude loss of permeability as determined by serial gas-injection slug tests, presumably due to observed mineral precipitation in the ZVI zone. As a result, a very shallow water table now threatens crop production and the proportion of treated ground water may have decreased significantly from an initial mass-balance estimate of 4 gallons per minute. Flux estimates based on Darcian principles are limited by high spatial and temporal variability. To alleviate the ground water mounding and provide additional treatment capacity a supplemental treatment cell was installed in June 2005. The cell is currently (July 2005) treating about 2.4 gpm. Performance data (flows, pressures, and pH), collected and transmitted daily to operations personnel, indicate that the cell is operating normally. Effluent concentration of uranium remains less than the ground water standard. While there are some operational and maintenance costs for the treatment cell, the costs are relatively minor. The amount of data required to confirm the performance of the treatment cell is much less than the amount required to confirm the performance of the PRB at a similar level of confidence.

Arsenic commonly occurs in groundwater as an oxyanion, and is mobile under the conditions that prevail in most aquifers. Several permeable reactive barrier (PRB) systems have been installed for treatment of As-contaminated groundwater. The PRB sites include mine tailings impoundments, fertilizer manufacturing sites, thermal-electric power generation and transmission facilities and chemical production plants. A variety of reactive materials have been used in these installations. Some of the PRBs use reactive materials which include zero valent iron (ZVI) filings either with or without an organic carbon (OC) source such as wood chips or compost. Other installations contain basic oxygen furnace (BOF) slag, a byproduct of the steel refining process. Removal of As to below drinking water guideline concentrations has been observed in all of these PRBs. The PRBs range from a few meters in length to 600 m long. The mechanisms responsible for As removal in the PRBs containing ZVI and OC include microbially mediated sulfate reduction followed by metal (As) sulfide precipitation and secondarily by adsorption and coprecipitation on the ZVI corrosion surfaces. In the BOF slag barriers As is removed by adsorption and secondary mineral precipitation. Studies of the reactive material using selective chemical extractions, mineralogical examination and surface analytical techniques (e.g., SEM and synchrotron radiation based methods) are being conducted to determine the specific forms of the reaction products.

These asbestos occurrences range from rocks that contain small amounts of the asbestos minerals as natural impurities to large asbestos ore bodies that were once mined for commercial and industrial uses. If naturally occurring asbestos (NOA) is disturbed and fibers are released into the air, then there is a potential risk to human health. As land that contains NOA is excavated and developed, the risk for environmental exposures increases. Airborne asbestos could become a health hazard in areas identified to contain NOA-bearing rock, especially where these rocks are exposed to natural weathering and human activities (excavation of natural outcroppings). The USGS map and database will allow State and local governments and the public at large to be aware of the distribution of known asbestos deposits and take appropriate precautionary measures if and when necessary. When publishing and releasing information about natural asbestos it is important to understand how this information will be used and received by stakeholders. The ultimate goal of communicating the hazards associated with natural asbestos is to prevent dispersion of NOA into the environment through human activities, and thus help prevent or greatly reduce human exposure and potential asbestos-related disease. Miscommunication can lead to unnecessary alarm at one extreme to possible minimization of the potential hazards at the other. This presentation will describe an interagency communication and education strategy for dealing with naturally occurring asbestos on a National level. We will discuss the overarching messages and content that target audiences need to understand in order to manage natural asbestos and protect public health.

Covering only 1-3% of the total land area, these ecosystems contain a disproportionally large percentage of the region's biodiversity. Stream incision is a major threat to these sensitive ecosystems. Rapid downcutting due to natural and anthropogenic disturbances lowers local water tables. Riparian vegetation requiring saturated soils or shallow water tables is then eliminated in favor of drier vegetation communities and valuable habitat is lost. Many of these upland watersheds are located in the Humboldt-Toiyabe National Forest and understanding the structure and function of riparian meadows and the impact of stream incision on these ecosystems has been a concern of the USDA Forest Service. Recently the Forest Service partnered with the U.S. EPA's Ecosystem Restoration and Risk Management Research Program. The objective of this EPA program is to conduct ecological protection and restoration research in order to provide scientifically defensible methods for resource managers to manage, rehabilitate, or restore ecosystems of local, regional, and national importance. A multidisciplinary research team of scientists from government and academia has been working to better understand the geologic and geomorphic settings, surface and subsurface hydrologic regimes, and vegetation patterns of upland riparian meadow systems in central Nevada. Additional investigations to date include mapping riparian corridor/meadow distribution, determining basin sensitivity to stream incision, characterizing levels of stream entrenchment and meadow degradation, prioritizing ecosystem degradation and restoration potential to better direct available resources, and evaluating the success of restoration alternatives. Results from this research will provide resource managers with information needed to successfully manage and restore threatened riparian ecosystems throughout upland watersheds in the Great Basin.

Previous work on these systems has focused on understanding a few study meadows in great detail. The logical next steps are to (1) look at more meadows throughout the central Great basin to investigate how broadly applicable these conclusions are and (2) to apply the knowledge gained in these specific studies to address the problem of meadow incision. Prior to this current phase of study, this was begun by examining the watershed level causes of sensitivity to stream incision. This study builds on this work by combining a watershed approach with a meadow specific approach. We are looking at both the local controls on meadow formation and maintenance, and how they relate to watershed level sensitivity. We used color enhanced satellite imagery to identify 1,300 previously unvisited riparian wetlands within the four target mountain ranges. We then narrowed this number down using topographic maps and aerial photos to 240 potential meadows, 170 of which were assessable by roads. By visiting some of these meadows we were able to further modify our selection criteria and narrow down the number of meadow visits to about 70 of the most promising meadows. 35 of these were chosen for intensive meadow study this summer. At each of these meadows we collected geomorphic data by surveying long profiles and cross sections, mapped and sampled vegetation communities, and mapped springs and geological controls on meadow persistence. The watershed level data on basin geology and morphometry was collected in the lab. The data collected for this study were used to categorize the meadows based on their potential stability and prioritize restoration activities in the region.

Channel incision can lower the baselevel for groundwater discharge and de-water meadow complexes resulting in a shift from wet meadow to dry land vegetation. The Kingston meadow is located immediately up-valley of a late Holocene age side-valley alluvial fan that progrades across the main valley. Channel instability starts where the main channel gradient steepens across side-valley fans. Once channel erosion breaches the baselevel established by the side-valley fan, incision migrates upstream through the meadow. Efforts to stabilize and maintain un-incised wet meadow complexes and restore degraded meadows must focus on channel morphology, channel dynamics, alluvial architecture, and hydrogeology, all of which are inherited from events that transpired during the middle to late Holocene. To characterize the system we have installed 97 groundwater piezometers, extracted 12 deep sediment cores, used seismic profiles and ground penetrating radar, installed multiple channel cross-sections, and conducted repeated total station based topographic surveys. Complex stratigraphic and hydrogeologic circumstances produce artesian flow in the most actively degrading portion of the system. Because groundwater sapping is an important erosive process in these degrading wet meadow systems, we have ruled out several restoration possibilities such as relocating the channel or a plug and pond approach. We installed a series of nine grade control structures beginning at the side-valley fan hinge-point and extending upstream into the meadow to facilitate sediment deposition, reconstruction of the channel profile, and regrading of the water table to a higher baselevel. An active sapping zone was stabilized by the installation of fiber logs and naturally occurring rushes and sedges. Preliminary results show that the channel has aggraded tens of centimeters in channel segments upstream of the grade control structures after one period of high flow sufficient to mobilize bed material. We will continue monitoring the channel's response to the stabilization efforts.

Understanding management and restoration options for riparian meadow complexes exhibiting stream incision requires knowledge of the relationships among riparian vegetation, geomorphic controls, and hydrologic regimes. The dominant plant species and vegetation states associated with meadow complexes in the central Great Basin are determined by water table depths and substrate characteristics and serve as indicators of hydrologic processes. Abiotic thresholds exist between vegetation states that can be defined by water table depths and substrates, while biotic thresholds exist within vegetation states that can be evaluated based on species composition. Stream incision associated with meadow complexes often results in declining water tables, abiotic threshold crossings and loss of wet meadow ecosystems. In actively incising systems, restoring wet meadow ecosystems once water tables have dropped is unrealistic. Restoration and management activities must be based upon the current potential of these systems to support a given vegetation state. This may involve prevention, i.e., stabilization of incising streams, or active restoration, i.e., management or revegetation based on the current water tables and substrate types.

An interdisciplinary group has investigated 1) the origin, characteristics, and controls on the evolution of these riparian meadows, and 2) the hydrologic and vegetative response to stream incision. Detailed data on groundwater (60-100 wells per site), surface water (gaging), geomorphology, stratigraphy (dozens of cores), geophysics (seismic and GPR), and vegetation have been collected in four meadow complexes with reconnaissance level data collected in dozens. Meadows are present in groundwater discharge zones with high flow rates that are geologically controlled to maintain high groundwater tables. Many of the meadows are present upstream of side-valley alluvial fans. The interplay of faults, differential sediment inputs from down valley and side valley sources, and alluvial fan form and sediments create conditions necessary for riparian meadows. Hydrologic conditions to support meadows can also be created by constrictions in alluvial fill either by basin shape or underlying bedrock geometry. Meadows terminate downstream where unconfined, high hydraulic conductivity layers permit rapid draining and lowering of the groundwater table. Artesian conditions are common in meadows because of the complex stratigraphy with strongly contrasting hydraulic conductivities and high hydraulic gradients. Many meadow complexes are undergoing stream incision because of current climatic conditions, basin sediment supplies, geomorphically and hydrologically sensitive conditions, and anthropogenic impacts. Entrenchment of meadows is enhanced in many places by groundwater sapping. Incision lowers the groundwater table, causes shifts in vegetation from wetter to drier species, may change groundwater flow paths, and, in extreme cases, may cause permanent loss of the meadow complex. The magnitude and type of response to incision varies with groundwater budget, hydraulic conductivity of sediments, and stratigraphy. Proper management of the wet meadow complexes, including stream restoration or stabilization, requires understanding the spatial and temporal complexities characteristic of these systems.

Measured partition coefficients (K (sub p) ) of Satilla River (Georgia) and Cape Fear River estuary (North Carolina) CDOM ranged from 19 to 233 L kg (super -1) when model freshwater and organic-rich estuarine sediments were added to solution (concentrations of 0.1, 1, or 10 gL (super -1) ), with the largest K (sub p) values measured in solutions with the lowest sediment concentrations. Sorption of Satilla River CDOM was augmented upon raising the ionic strength of solution by mixing with natural seawater, likely due to the 'salting out effect' of Ca (super +2) and Mg (super +2) ions. For turbid estuarine systems with particle loads of approximately 100 mg L (super -1) , we estimate that approximately 1-2% of the CDOM pool sorbs to settling particles, facilitating the transfer to a potentially large colored particulate organic matter (CPOM) reservoir within sediments. Our results also indicate that >30% of the colored organic matter pool within sediment pore waters (sediment concentration >10 g L (super -1) ) may exist as CPOM. Spectral slope coefficients (300-700nm) of initial CDOM samples increased as much as 20% after mixing with 10 g L (super -1) sediment and 5% after mixing with 1 g L (super -1) sediment indicating that sorption to particles has the potential to significantly alter the optical properties of CDOM in the water column of turbid shallow environments or in areas of high benthic exchange.

These meadow complexes are currently degrading due to stream channel incision that alters the associated ecosystems. The Great Basin Ecosystem Management (GBEM) project is a multidisciplinary program that is focused on the understanding and restoration of these riparian complexes. One feature of interest is the geometry of bedrock beneath the meadows, especially in areas where alluvial fans at the downstream end of the meadows are present. It is hypothesized that side-valley alluvial fans interact with fault-related bedrock steps to constrict ground water flow and raise the water table, creating wet meadows. Testing this hypothesis (or alternatives that result from examining the data) is critical in the development of a logical, long-term, and robust management plan for protecting and restoring existing meadow complexes. Seismic and ground penetrating radar (GPR) geophysical surveys have been conducted in six riparian meadow complexes in the Central Great Basin from 2003-2005. Over 8 km of seismic profile and more than 70 GPR profiles (in 2D and pseudo-3D) have been collected. These data yield information directly on depth to bedrock. In addition, the seismic data yields deeper structural information on the nature of bedrock topology variations while the GPR data yields near-surface information on the bedrock-controlled stratigraphic variability. The fusion of the two geophysical techniques, therefore, will provide more information than would be available otherwise (using only a single imaging technique) to understand the bedrock and associated sedimentology controls on the meadow formation. These data will also be supported and supplemented by existing subsurface geologic and hydrologic information obtained from the borehole drilling program.

First, a remote sensor derived, land cover classification was performed to support modeling needs. Modeling efforts included the development of a mass balance model to quantify potential N sources and sinks, followed by a precipitation event driven hydrologic model to effectively transport excess N across the landscape to individual stream reaches to support subsequent labeling of transported N values corresponding to source origin. Results indicated that agricultural land contributed 55 percent of the total annual NPS-N loadings, followed by forested land at 23 percent (background), and urban areas at 21 percent. Average annual N source contributions were quantified for agricultural (1.4 kg/ha), urban (1.2 kg/ha), and forested cover types (0.5 kg/ha). Nonpoint source-N contributions were greatest during the winter (40 percent), followed by spring (32 percent), summer (28 percent), and fall (0.3 percent). Seasonal total N loadings shifted from urban dominated and forest dominated sources during the winter, to agricultural sources in the spring and summer. A quantitative assessment of the significant NRB land use activities indicated that high (greater than 70 percent impervious) and medium (greater than 35 percent impervious) density urban development were the greatest contributors of NPS-N on a unit area basis (1.9 and 1.6 kg/ha/yr, respectively), followed by row crops and pasture/hay cover types (1.4 kg/ha/yr).

Of 224 children contained in the original data set, 160 children were found to have longitudinal measurements of O3 concentrations in at least six months of 12 months of the study period. Data for these children were randomly split into two equal sets: one for model development and the other for model validation. Mixed models with various variance-covariance structures were developed to evaluate statistically important predictors for chronic personal ozone exposures. Model predictions were then validated against the field measurements using an empirical best-linear unbiased prediction technique. The results of model fitting showed that the most important predictors for personal ozone exposure include indoor O3 concentration, central ambient O3 concentration, outdoor O3 concentration, season, gender, outdoor time, house fan usage, and the presence of a gas range in the house. Hierarchical models of personal O3 concentrations indicate the following levels of explanatory power for each of the predictive models: indoor and outdoor O3 concentrations plus questionnaire variables, central and indoor O3 concentrations plus questionnaire variables, indoor O3 concentrations plus questionnaire variables, central O3 concentrations plus questionnaire variables, and questionnaire data alone on time activity and housing characteristics. These results provide important information on key predictors of chronic human exposures to ambient O3 for children and offer insights into how to reliably and cost-effectively predict personal O3 exposures in the future. Furthermore, the techniques and findings derived from this study also have strong implications for selecting the most reliable and cost-effective exposure study design and modeling approaches for other ambient pollutants, such as fine particulate matter and selected urban air toxics.

Included in this charge was a requirement to implement an on-board diagnostic (OBD) test for both basic and enhanced I/M programs. This paper provides the results to date of an ongoing EPA study undertaken to assess the durability of the OBD system as vehicles age and as mileage is accrued. The primary results of this effort indicate the points described below. First, the majority of high-mileage vehicles tested had emission levels within their certification limits, and their malfunction indicator light (MIL) was not illuminated, indicating that the systems are capable of working throughout the life of a vehicle. Second, OBD provides better air quality benefits than an IM240 test (using the federal test procedure [FTP] as the benchmark comparison). This statement is based on greater emissions reductions from OBD-directed repairs than reductions associated with IM240-identified repairs. In general, the benefits of repairing the OBD fails were smaller, but the aggregate benefits were greater, indicating that OBD tests find both the high-emitting and a number of marginally high-emitting vehicles without false failures that can occur with any tailpipe test. Third, vehicles that truly had high-tailpipe emissions as confirmed by laboratory IM240 and FTP testing also had illuminated MILs at a statistically significant level. Last, field data from state programs have demonstrated MIL illumination rates comparable with those seen in this work, suggesting that the vehicles sampled in this study were representative of the larger fleet. Nonetheless, it is important to continue the testing of high-mileage OBD vehicles into the foreseeable future to ensure that the systems are operating correctly as the fleet ages and as changes in emission certification levels take effect.

A wealth of standard toxicological studies and targeted research efforts relating to this adverse effect is available, and these were used to evaluate the utility of the Human Relevance Framework (HRF) for noncancer health effects. The hypothesized mode of action involved inhibition of the hydrolysis of cholesterol from high-density lipoprotein in the rat testes, followed by an androgen withdrawal syndrome on spermatogenesis. Some evidence is available that a similar mode of action would not be operable in humans. Despite the wealth of studies conducted in the rat, the weight of evidence is insufficient to define the mode of action for reproductive toxicity in the male rat. A principal deficiency in the database was discordance between the exposure levels observed to cause biochemical disturbances in the testes related to the hypothesized mode of action and the dose levels observed to induce the adverse outcome on spermatogenesis. For this reason, a complete MOA/human relevance analysis is not possible and, based on traditional risk assessment principles, any toxic effects are assumed to be relevant for human risk assessment.

In November 2003, the International Life Sciences Institute's Risk Science Institute (ILSI RSI) published a 2-year study using animal and human MOA information to generate a four-part Human Relevance Framework (HRF) for systematic and transparent analysis of MOA data and information. Based mainly on non-DNA-reactive carcinogens, the HRF features a 'concordance' analysis of MOA information from both animal and human sources, with a focus on determining the appropriate role for each MOA data set in human risk assessment. With MOA information increasingly available for risk assessment purposes, this article illustrates the further applicability of the HRF for reproductive, developmental, neurologic, and renal endpoints, as well as cancer. Based on qualitative and quantitative MOA considerations, the MOA/human relevance analysis also contributes to identifying data needs and issues essential for the dose-response and exposure assessment steps in the overall risk assessment.

The air pollution, resulting from combustion of coal for industry and home heating in the Teplice district of the Czech Republic, was much higher during the winter than at other times of year with peaks exceeding US air quality standards. METHODS: Young men from Teplice were sampled up to seven times over 2 years allowing evaluation of semen quality after periods of exposure to both low and high air pollution. Routine semen analysis (sperm concentration, motility and morphology) and tests for sperm aneuploidy and chromatin integrity were performed, comparing measurements within each subject. Exposure was classified as high or low based on data from ambient air pollution monitoring. RESULTS: Using repeated measures analysis, a significant association was found between exposure to periods of high air pollution (at or above the upper limit of US air quality standards) and the percentage of sperm with DNA fragmentation according to sperm chromatin structure assay (SCSA). Other semen measures were not associated with air pollution. CONCLUSION: Exposure to intermittent air pollution may result in sperm DNA damage and thereby increase the rates of male-mediated infertility, miscarriage, and other adverse reproductive outcomes.

The causal link between global warming and increased greenhouse gas emissions is well established. Carbon dioxide levels are at a higher level than at any time in the past 750 000 years at least, and it is too late to stop further warming and consequent impacts on UK and global societies. Here I summarize the latest scientific evidence for anthropogenic global warming and outline strategies for adapting to its impacts and mitigating the effects in the longer term.

Because such exposures often involve occupational activities of adults, the ALM was directed at assessing soil- related lead risks to adults. Consistent with other approaches used in Superfund risk assessment, the ALM was designed to predict quasi-steady state blood lead concentrations (PbB) that might result from soil exposure. These predictions are converted to a risk estimate, expressed as the probability of exceeding a PbB level of concern. To examine the assumptions and variables in the ALM that have become available since 1996, a comparison was made of the attributes of seven alternative research models for which adequate documentation is available to understand and implement each approach. Several of these models have been used in regulatory decision-making; however, the USEPA has officially embraced none for general use. This analysis suggests that the ALM can continue to serve as a reasonable tool for assessing risks associated with non-residential exposures to soil. Under certain circumstances other models may be more applicable ( i . e ., for assessing acute or intensive exposures); however, the ALM is recommended for the majority of risk assessment applications.

Organismal and Thyroidal Responses to the Model Compounds 6-Propylthiouracil, Methimazole, and Thyroxine AN - 19421080; 6530060 AB - In response to the initial Endocrine Disruptor Screening and Testing Advisory Committee (EDSTAC) recommendations, research was conducted on the development of a Xenopus laevis based tail resorption assay for evaluating thyroid axis disruption. This research highlighted key limitations associated with relying on tail resorption as a measure of anti/thyroid activity. The most critical limitation being that tail tissues of tadpoles at metamorphic climax are insensitive to perturbation by thyroid axis agonists/antagonists. To improve upon the initial proposal, we have conducted experiments comparing the sensitivity of pre-metamorphic (stage 51) and pro-metamorphic (stage 54) larvae to the model thyroid axis disruptors methimazole (control, 6.25, 12.5, 25, 50, 100 mg/l), 6-propylthiouracil (PTU) (control, 1.25, 2.5, 5, 10, and 20 mg/l), and thyroxine (T4) (0.25, 0.5, 1, 2, 4 mu g/l). Exposures were conducted using two different experimental designs. For experimental design 1, tadpoles were exposed to methimazole or PTU starting at either NF stage 51 or NF 54 for 14 days. For experimental design 2, tadpoles were exposed to PTU or T4 starting at NF stage 51 or NF 54 for 14 and 21 days, respectively. Methimazole and PTU, which are thyroid hormone synthesis inhibitors, both caused a concentration dependent delay in larval development. As determined from this endpoint, there were only minor differences in sensitivity observed among the two stages examined. Further, both compounds caused concentration dependent changes in thyroid gland morphology. These changes were characterized as reduced colloid, glandular hypertrophy, and cellular hyperplasia and hypertrophy. Treatment failed to negatively affect growth, even in tadpoles that experienced significant metamorphic inhibition. T4 treatment resulted in a concentration dependent increase in developmental rate, as would be expected. Similar to studies with methimazole, there were no differences in sensitivity among the two developmental stages examined. These results indicate that tadpoles in the early stages of metamorphosis are sensitive to thyroid axis disruption and that development of a short-term, diagnostic amphibian-based thyroid screening assay shows considerable promise.

A Case Example of the Assessment of Ozone Monitor Network Options AN - 17437473; 6559792 AB - Limited time and resources usually characterize environmental decision making at policy organizations such as the U.S. Environmental Protection Agency. In these climates, addressing uncertainty, usually considered a flaw in scientific analyses, is often avoided. However, ignoring uncertainties can result in unpleasant policy surprises. Furthermore, it is important for decisionmakers to know how defensible a chosen policy option is over other options when the uncertainties of the data are considered. The purpose of this article is to suggest an approach that is unique from other approaches in that it considers uncertainty in two specific ways-the uncertainty of stakeholder values within a particular decision context and data uncertainty in the light of the decision-contextual data-values relationship. It is the premise of this article that the interaction between data and stakeholder values is critical to how the decision options are viewed and determines the effect of data uncertainty on the relative acceptability of the decision options, making the understanding of this interaction important to decisionmakers and other stakeholders. This approach utilizes the recently developed decision analysis framework and process, multi-criteria integrated resource assessment (MIRA). This article will specifically address how MIRA can be used to help decisionmakers better understand the importance of uncertainty on the specific (i.e., decision contextual) environmental policy options that they are deliberating.

However, the persistence of these effects and the conditions necessary for their appearance are not clear: two specific concerns are whether symptomatic poisoning is necessary for persistent effects, and whether inhibition of cholinesterase (ChE) activity is a protective metric of OP exposure. This study examined the effects of chronic dietary and repeated high-level acute exposure to the pesticide chlorpyrifos (diethyl 3,5,6-trichloro-2-pyridyl phosphorothionate, CPF) on learning and attention. Beginning at 3 months of age, male Long-Evans rats received dietary CPF at a daily dose of 0, 1, or 5 mg/kg for 1 year. Half of each dietary group also received an acute oral dose of CPF (initial dose at 60 mg/kg, 5 doses at 45 mg/kg) every 2 months. Beginning 2 weeks before the fourth acute dose, behavioral assessments were conducted on the eight rats in each of the six exposure groups (0-Oil, 0-CPF, 1-Oil, 1-CPF, 5-Oil, and 5-CPF). Using an auto-shaping procedure, the groups learned to press a lever for food in the following order: 5-Oil, 5-CPF, 1-Oil, and 0-Oil. The 0-CPF and 1-CPF groups did not learn the response in three 50-trial sessions. Chronic CPF did not affect acquisition of other behaviors required by a signal detection task (SDT) designed to assess sustained attention. The sixth acute CPF dose significantly disrupted the SDT in all dosed groups. Two months after the end of dosing, performance of the SDT was impaired in the 5-CPF group. These data suggest that learning the contingency between an action and reward may be accelerated by chronic exposure to CPF and inhibited by previous symptomatic exposure to CPF, and that persistent cognitive impairment may follow if CPF exposure inhibits brain ChE activity and is accompanied by acute doses sufficient to induce signs of toxicity.

The probability of impact at differing levels of nonpoint source pollution was determined using the biological response of instream organisms empirically obtained from a statistical survey. A conditional probability analysis was used to calculate a biological threshold of impact as a function of the likelihood of exceeding a given value of pollution metric for a specified geographic area. Uncertainty and natural variability were inherently incorporated into the analysis through the use of data from a probabilistic survey. Data from wadable streams in the mid-Atlantic area of the U.S. were used to demonstrate the approach. Benthic macroinvertebrate community index values (EPT taxa richness) were used to identify impacted stream communities. Percent fines in substrate (silt/clay fraction, < 0.06 mm) were used as a surrogate indicator for sedimentation. Thresholds of impact due to sedimentation were identified by three different techniques, and were in the range of 12 to 15 percent fines. These values were consistent with existing literature from laboratory and field studies on the impact of sediments on aquatic life in freshwater streams. All results were different from values determined from current regulatory guidance. Finally, it was illustrated how these thresholds could be used to develop criterion for protection of aquatic life in streams.

The mixed NAPL density and interfacial tension behaved ideally, as predicted by the volume ratio. The mixed NAPL viscosity increased exponentially from that of the pure CE to that of pure SoyOil as the volume fraction increased. The measured contact angle was highly variable and was unpredictable as a function of the volume composition of the mixed NAPL, The physical property effects indicate that the mobilization of residual CE NAPLs because of SoyOil injection is unlikely. Equilibrium dissolution of CEs from the NAPL mixtures behaved linearly as a function of the mole fraction. Dissolved SoyOil in simulated groundwater enhanced the dissolution of trichloroethene (TCE) during flow tests, increasing the effluent TCE concentration from 141 to 202 mg/L. The ready intermingling of the CE dense nonaqueous phase liquids (DNAPLs) and SoyOil indicate that such interactions may be significant at sites where vegetable oil is injected into DNAPL source areas to enhance in situ anaerobic bioremediation.

To evaluate the effect that free iodide has on thyroid toxicity, we exposed rats for 2 weeks by daily gavage to sodium iodide (NaI). To compare the effects of compounds with alternative mechanisms (increased thyroid hormone metabolism and decreased thyroid hormone synthesis, respectively), we also examined phenobarbital (PB) and propylthiouracil (PTU) as model thyroid toxicants. Follicular cell hypertrophy and pale-staining colloid were present in thyroid glands from PB-treated rats, and more severe hypertrophy/colloid changes along with diffuse hyperplasia were present in thyroid glands from PTU-treated rats. In PB-and PTU-treated rats, thyroid-stimulating hormone (TSH) levels were significantly elevated, and both thyroxine and triiodothyronine hormone levels were significantly decreased. PB induced hepatic uri-dine diphosphate-glucuronyltransferase (UDPGT) activity almost 2-fold, whereas PTU reduced hepatic 5'-deiodinase I (5'-DI) activity to < 10% of control in support of previous reports regarding the mechanism of action of each chemical. NaI also significantly altered liver weights and UDPGT activity but did not affect thyroid hormone levels or thyroid pathology. Thyroid gene expression analyses using Affymetrix U34A GeneChips, a regularized t-test, and Gene Map Annotator and Pathway Profiler demonstrated significant changes in rhodopsin-like G-protein-coupled receptor transcripts from all chemicals tested. NaI demonstrated dose-dependent changes in multiple oxidative stress-related genes, as also determined by principal component and linear regression analyses. Differential transcript profiles, possibly relevant to rodent follicular cell tumor outcomes, were observed in rats exposed to PB and PTU, including genes involved in Wnt signaling and ribosomal protein expression.

The population status and distributional changes of amphibians were investigated over a 20,000-km super(2) area in the eastern Mojave Desert in 2 ways. For upland sites (i.e., sites outside of major valleys and river floodplains), where wetland habitat is almost exclusively springs, encounter surveys were conducted at 128 sites in 1997-1999, and results were compared to historical (pre-1970) locality records. For lowland sites (i.e., sites within major valleys and river floodplains), locality records and field surveys in 1995-2004 were reviewed to detect changes in distribution over time. Amphibians were found at 79% of upland sites. By far the most common species was the red-spotted toad (Bufo punctatus, 73% of sites), followed by the Pacific chorus frog (Pseudacris regilla), Woodhouse's toad (B. woodhousii), relict leopard frog (Rana onca), and the introduced American bullfrog (R. catesbeiana). Taxa observed or collected in the lowlands since 1990 were Woodhouse's toad, Pacific chorus frog, American bullfrog, and the introduced tiger salamander (Ambystoma tigrinum). Four taxa (Vegas Valley leopard frog [Rana sp.], Arizona toad [B. microscaphus], Great Plains toad [B. cognatus], and Great Basin spadefoot [Spea intermontana]) had historical records but no evidence of occurrence in the study area within the past 5 decades. The amphibian fauna of the study area has changed dramatically in the past century, primarily at lowland sites where habitat loss and modification have been extreme. Striking changes are the nearly complete replacement of native leopard frogs (i.e., Vegas Valley and relict leopard frogs) with the introduced bullfrog, and the complete replacement of the Arizona toad in Las Vegas Valley with Woodhouse's toad or hybrids with predominantly Woodhouse's traits. In contrast, the distributions of 2 species characteristic of upland springs, red-spotted toad and Pacific chorus frog, appear to have changed little from their historical distributions, despite habitat modification at many sites.

A major source was determined to be the gas clothes dryer. Although the dryer was vented to the outdoors it consistently produced an order of magnitude increase in the ultrafine concentrations compared to times with no indoor sources. Short-term peak number concentrations exceeded 100,000 cm super(-3) on a number of occasions. The source strength was conservatively estimated at about 6x10 super(12) ultrafine particles produced per drying episode. These values are underestimates, since the part of the peak below 9.8 nm was not measured. Averaged over 150 h of operation, the number concentration showed a major peak at the smallest size measured (9.8 nm) and a secondary peak at 30 nm. Loss rates of the ultrafines due to diffusion, deposition, and particle growth (1-2 h super(-1)) were high compared to losses due to air exchange (0.1-0.6 h super(-1)). Considering the reported health effects of ultrafines, the widespread use of gas dryers, and the substantial amount of time that gas dryers are operated in many homes, it may be desirable to carry out further research to determine if the results reported here for a single dryer in one home are reproducible under different conditions.

To evaluate the aquatic toxicity of individual pharmaceuticals and mixtures, we performed single species laboratory toxicity tests with Daphnia magna, a common freshwater zooplankton. We conducted acute (6-day) and chronic (30-day) exposure pharmaceutical bioassays and evaluated survivorship and morphology of adults and neonates, adult length, resting egg production, brood size (fecundity), and the proportion of male broods produced (sex ratio). In general, exposure to a single pharmaceutical in the 1-100 mu g/l range yielded no apparent effects on the normal life processes of Daphnia. However, chronic fluoxetine exposure (36 mu g/l) significantly increased Daphnia fecundity, and acute clofibric acid exposure (10 mu g/l) significantly increased sex ratio. A mixture of fluoxetine (36 mu g/l) and clofibric acid (100 mu g/l) caused significant mortality; the same fluoxetine concentration mixed with 10 mu g/l clofibric acid resulted in significant deformities, including malformed carapaces and swimming setae. Mixtures of three to five antibiotics (total antibiotic concentration 30-500 mu g/l) elicited changes in Daphnia sex ratio. We conclude: (1) individual and mixtures of pharmaceuticals affect normal development and reproduction of Daphnia magna, (2) aquatic toxicity of pharmaceutical mixtures can be unpredictable and complex compared to individual pharmaceutical effects, and (3) timing and duration of pharmaceutical exposure influence aquatic toxicity.

We used a combination of experimental manipulations and simulation modeling to investigate the effects of interactions between cattle grazing and regional climate change on vernal pool communities. Data from a grazing exclosure study indicated that 3 years after the removal of grazing, ungrazed vernal pools dried an average of 50 days per year earlier than grazed control pools. Modeling showed that regional climate change could also alter vernal pool hydrology. Increased temperatures and winter precipitation were predicted to increase periods of inundation. We evaluated the ecological implications of interactions between grazing and climate change for branchiopods and the California tiger salamander ( Ambystoma californiense) at four sites spanning a latitudinal climate gradient. Grazing played an important role in maintaining the suitability of vernal pool hydrological conditions for fairy shrimp and salamander reproduction. The ecological importance of the interaction varied nonlinearly across the region. Our results show that grazing can confound hydrologic changes driven by climate change and play a critical role in maintaining the hydrologic suitability of vernal pools for endangered aquatic invertebrates and amphibians. These observations suggest an important limitation of impact assessments of climate change based on experiments in unmanaged ecosystems. The biophysical impacts of land management may be critical for understanding the vulnerability of ecological systems to climate change.Original Abstract: Los impactos del cambio climatico en buena medida dependen de decisiones de gestion de tierras; sin embargo, raramente se han cuantificado las interacciones entre los cambios globales y la gestion de recursos. Utilizamos una combinacion de manipulaciones experimentales y modelos simulados para investigar los efectos de las interacciones entre el apacentamiento de ganado y el cambio climatico regional sobre comunidades en charcas primaverales. Los datos de un estudio de exclusion de apacentamiento indicaron que, 3 anos despues de eliminar el apacentamiento, las charcas primaverales no apacentadas se secaban 50 dias por ano en promedio antes que las charcas control con apacentamiento. El modelado mostro que el cambio climatico regional tambien podia alterar la hidrologia de las charcas primaverales. Se predijo que el aumento de temperatura y de precipitacion invernal incrementaria los periodos de inundacion. Evaluamos las implicaciones ecologicas de las interacciones entre apacentamiento y cambio climatico sobre braquiopodos y la salamandra tigre de California ( Ambystoma californiense) en cuatro sitios a lo largo de un gradiente latitudinal. El apacentamiento jugo un papel importante en el mantenimiento de condiciones hidrologicas adecuadas para la reproduccion de braquiopodos y salamandras en las charcas. La importancia ecologica de la interaccion vario no linealmente en la region. Nuestros resultados indican que el apacentamiento puede enmascarar los cambios hidrologicos derivados del cambio climatico y jugar un papel critico en el mantenimiento de la aptitud hidrologica de las charcas primaverales para invertebrados acuaticos y anfibios en peligro de extincion. Estas observaciones sugieren una importante limitacion de las evaluaciones de impactos del cambio climatico basadas en experimentos en ecosistemas en los que no hay actividades de gestion. Los impactos biofisicos de la gestion de tierras puede ser criticos para el entendimiento de la vulnerabilidad de los sistemas ecologicos al cambio climatico.

AN - 68650875; 16201620 AB - Solar-radiation-induced photochemistry can be considered as a new source of nutrients when photochemical reactions release bioavailable nitrogen from biologically nonreactive dissolved organic nitrogen (DON). Pretreatments of Baltic Sea waters in the dark indicated that >72% of DON was recalcitrant to biological mineralization. When this DON (16-21.5 microM) was exposed to simulated solar radiation, the concentration of NH4+ increased 0.5-2.5 microM more in irradiated waters than in the dark controls. The photochemical production of NH4+ and the dose of absorbed photons were used to calculate the apparent quantum yield spectrum for photoammonification [mol NH4+ (mol photons)(-1) nm(-1)] at wavelengths (lambda) of 290-700 nm (phiNH4,lambda). The modeled mean rates of photoammonification based on phiNH4,lambda were 143 and 53 micromol NH4+ m(-2) d(-1) at the surface and in the whole water column, respectively, of Baltic Sea stations during summer. The results of this study indicate thatthe rate of photoammonification approximately equals and periodically exceeds the rate of atmospheric deposition of reactive inorganic nitrogen to the northern Baltic Sea. Forthese stratified surface waters beyond riverine input of labile nitrogen, photoammonification can periodically be the largest source of new bioavailable nitrogen.

AN - 68647531; 16201644 AB - During moment-based analyses of partitioning tracer tests, systematic errors in volume and concentration measurements propagate to yield errors in the saturation and volume estimates for nonaqueous phase liquid (NAPL). Derived expressions could be applied to help practitioners bracket their estimates of NAPL saturation and volume obtained from such tests. In practice, many of these effects may be overshadowed by other complications experienced in the field. Errors are propagated for systematic constant (offset) volume, proportional volume, and constant (offset) concentration errors. Previous efforts to quantify the impact of these errors were predicated upon the specific assumption that nonpartitioning and partitioning masses were equal. The current work relaxes that assumption and is therefore more general in scope. Through the use of nondimensional concentration, systematic proportional concentration errors do not affect the accuracy of the method. Specific consideration needs to be given to accurate flow measurements and minimizing baseline concentration errors when performing partitioning tracer tests in order to prevent the propagation of systematic errors.

AN - 68647237; 16201645 AB - The uncertainty in NAPL volume estimates obtained through partitioning tracers can be quantified as a function of random errors in volume and concentration measurements when moments are calculated from experimentally measured breakthrough curves using the trapezoidal rule for numerical integration. The methodology is based upon standard stochastic methods for random error propagation. Monte Carlo simulations using a synthetic data set derived from the one-dimensional solution of the advective-dispersive equation serve to verify the process. It is shown that the uncertainty in NAPL volume predictions nonlinearly increases as the retardation factor decreases. An important result of this observation is that there is a large degree of uncertainty in using partitioning tracers to conclude NAPL is absent from the swept zone. Under the conditions investigated, random errors in concentration measurements are shown to have a greater impact on NAPL volume uncertainty than random errors in volume measurements, and it is also shown that uncertainty in NAPL volume decreases as the resolution of the breakthrough curves increases. The impact of uncertainty in background retardation (i.e., sorption of partitioning tracers in the absence of NAPL) was also investigated, and it likewise indicated that the relative uncertainty in NAPL volume estimates increases as the retardation factor decreases.

AN - 69048854; 16386000 AB - A liquid chromatography/tandem mass spectrometry (LC/MS/MS) method has been developed for the determination of 14 parent triazole fungicides and 8 of their metabolites found in apples, peaches, flour, raw water, and tap water. The triazole fungicides chosen for this multiresidue method development project included propiconazole, fenbuconazole and its RH-9129 and RH-9130 metabolites, cyproconazole, difenoconazole, tebuconazole and its HWG 2061 metabolite, hexaconazole, bromuconazole (both stereoisomers), epoxiconazole, tetraconazole, triticonazole and its RPA-404886 and RPA-406341 metabolites, triadimefon, triadimenol, and myclobutanil. Of special concern to the U.S. Environmental Protection Agency were the metabolites common to all triazole fungicides: free triazole, 1,2,4-triazole (T), and its 2 conjugates: triazolylalanine (TA) and triazolylacetic acid (TAA). These metabolites were the primary focus of this project. All samples we cleaned up by a combination of C18 solid-phase extraction (SPE), mixed-mode cationic SPE, and mixed-mode anionic SPE columns. A triple-stage quadrupole mass spectrometer, equipped with electrospray ionization in the positive-ion mode, was used to determine the compounds of interest. T, TA, and TAA were quantitated using isotopically labeled internal standards (IS), in which the 1,2,4-triazole ring had been synthesized by using 13C and 15N (IS_T, IS_TA, and IS_TAA). These isotopically labeled internal standards were necessary to correct for matrix effects. The T, TA, and TAA metabolites were quantitated at the 25-50 parts-per-billion (ppb) level in food commodities and at 0.50 ppb in water. Recoveries were 70-101% from apples, 60-121% from peaches, 57-118% from flour, 75-99% from raw water, and 79-99% from tap water.

AN - 68771787; 16274088 AB - Scale-up of a hollow-fiber-membrane (HFM) bioreactor treating trichloroethylene- (TCE-) contaminated water via co-metabolism with the methanotroph Methylosinus trichosporium OB3b PP358 was investigated through cost comparisons, bioreactor experiments, and mathematical modeling. Cost comparisons, based on a hypothetical treatment scenario of 568-L/min (150-gpm) flowrate with an influent TCE concentration of 100 microg/L, resulted in a configuration of treatment trains with two HFM modules in series and an overall annual cost of US dollar 0.36/m3 treated. Biological experiments were conducted with short lumen and shell residence times, 0.16 and 0.40 min, respectively, as a result of the cost comparisons. A new variable, specific transformation, was defined for characterizing the cometabolic transformation in continuous-flow systems, and values as large as 38.5 microg TCE/mg total suspended solids were sustainable for TCE treatment. Using mathematical modeling, HFM bioreactor system design was investigated, resulting in a five-step system design strategy to facilitate sizing of the unit processes.

AN - 68720974; 16111859 AB - Hypothermia is often seen in mice and rats exposed acutely to marine algal toxins, but the mechanism of action of these toxins on thermoregulation is not well understood. Our laboratory has assessed the thermoregulatory mechanisms of two marine algal toxins, maitotoxin and brevetoxin in the mouse. Radiotelemetry was used to measure core temperature in the unrestrained mouse while it was housed in a temperature gradient allowing the exhibition of thermoregulatory behavior. Both maitotoxin (338 ng/kg) and brevetoxin (180 microg/kg) were shown to elicit profound hypothermic responses accompanied by a preference for cooler ambient temperatures in the gradient. This behavioral response would suggest that the toxins alter the central neural control of body temperature, resulting in a regulated reduction in body temperature. Following recovery from the acute hypothermic effects of brevetoxin, mice developed an elevation in their daytime core temperature that persisted for several days after exposure. This fever-like response may represent a delayed toxicological effect of the marine algal toxins that is manifested through the thermoregulatory system. Overall, algal toxins have acute and delayed effects on temperature regulation in the mouse. A better understanding of the mechanisms of action of the toxins on thermoregulation should lead to improved methods for treating victims of ciguatera and other toxin exposures.

AN - 68719030; 16040230 AB - While there is a long-standing tradition of using behavioral methods to study the effects of manufactured drugs and environmental chemicals, comparatively little attention has focused until recently on the behavioral effects of marine or freshwater toxins. A vast array of microorganisms, found in a variety of waters, are known to occasionally "bloom" and produce toxins that can cause either blatant toxicity (i.e., lethality) or damage to a number of organ systems. The nervous system is a known target for many of the toxins. Considerable research has in the past been carried out to determine toxin effects on the survivability of laboratory rodents (typically mice) following acute exposures. Newer research has shown, however, prominent toxin-induced alterations in motor, sensory, autonomic and cognitive functions at sublethal exposure concentrations. Future toxin research can capitalize upon a wealth of behavioral paradigms already available in toxicology, pharmacology and neuroscience.

AN - 68716488; 16102938 AB - Blooms of toxigenic organisms have increased in spatial and temporal extent due to human activities and natural forces that alter ecologic habitats and pollute the environment. In aquatic environments, harmful algal blooms pose a risk for human health, the viability of organisms, and the sustainability of ecosystems. The estuarine dinoflagellate, Pfiesteria piscicida, was discovered in the late 1980s at North Carolina State University as a contaminant in fish cultures. P. piscicida was associated with fish death in laboratory aquaria, and illness among laboratory workers who inhaled the mist above aquaria. Both the fish and humans exhibited signs of toxicity. During the 1990s, large-scale mortality among fish and other aquatic organisms was associated with high concentrations of Pfiesteria sp. in estuaries on the eastern seaboard of North America from New York to Texas. Illness among humans was associated with direct exposure to estuaries and exposures to estuarine aerosols around the time of Pfiesteria-related fish kills. This review of the scientific literature on associations between Pfiesteria and human illness identified some of the possible mechanisms of action by which putative Pfiesteria toxins may have caused morbidity. Particular attention was given to the Pfiesteria-associated, human-illness syndrome known as Possible Estuary Associated Syndrome (PEAS). PEAS was characterized by multiple-system symptoms, deficits in neuropsychological tests of cognitive function, and rapid and severe decrements in visual contrast sensitivity (VCS), an indicator of neurologic function in the visual system. PEAS was diagnosed in acute and chronic illness cases, and was reacquired during re-exposure. Rapid normalization of PEAS signs and symptoms was achieved through the use of cholestyramine therapy. Cholestyramine, a non-absorbable polymer, has been used by humans to lower cholesterol levels since it was approved for that use by the U.S. Food and Drug Administration in 1958. When dissolved in water or juice and taken orally, cholestyramine binds with cholesterol, bile acids, and salts in the intestines, causing them to be eliminated rather than reabsorbed with bile during enterohepatic recirculation. Cholestyramine also has been reported to bind and eliminate a variety of toxic substances. The efficacy of cholestyramine therapy in treatment of PEAS supported the hypothesis that PEAS is a biotoxin-associated illness.

AN - 68640764; 16193761 AB - Perfluorooctanesulfonate (PFOS) is a widespread environmental contaminant emanating from the production and/or metabolism of fluorinated chemicals with a variety of applications. The goal of this work was to assess the toxicity and bioconcentration of PFOS in the fathead minnow (Pimephales promelas). Sexually mature fish were exposed via the water for 21 d to 0 (control), 0.03, 0.1, 0.3, or 1 mg PFOS/L, and effects on reproductive capacity and endocrinology were assessed. To determine possible developmental effects, a subset of embryos from parental exposures at each test concentration were held for an additional 24 d in the same PFOS treatments. A concentration of I mg PFOS/L was lethal to adults within two weeks. The 21-d 50% effect concentration (95% confidence interval) for effects on fecundity of the fish was 0.23 (0.19-0.25) mg PFOS/L. Exposure to PFOS caused various histopathological alterations, most prominently in ovaries of adult females. Adult males exposed to 0.3 mg PFOS/L for 21 d exhibited decreased aromatase activity and elevated concentrations of plasma 11-ketotestosterone and testosterone. No significant adverse effects on survival or growth were observed in developing fathead minnows held for 24 d at PFOS concentrations up to 0.3 mg/L. Adult fathead minnows readily accumulated PFOS from the water. The largest concentrations of PFOS were in blood, followed by liver and then gonad; for all tissues, females accumulated higher concentrations than males. Water and tissue concentrations of PFOS associated with effects in this study exceeded those reported for samples collected from the field by two to three orders of magnitude, suggesting that the current risk of PFOS on aspects of fish reproduction and development assessed in this study would be small.

AN - 68586627; 15602583 AB - The longitudinal NHEXAS-Maryland study measured metals, PAHs, and pesticides in several media to capture temporal variability. Questionnaires were concurrently administered to identify factors that influenced changes in contaminant levels over time. We constructed mixed-effects regression models for lead, phenanthrene, and chlorpyrifos (including metabolites) in indoor air, dust, dermal wipes, and biological fluids. Significant predictors represented time-varying activities as well as unchanging housing and demographic factors. There was little overlap among the models, with predictors generally reflecting the diverse characteristics of the target compounds. We estimated between- and within-person variance components to evaluate the reliability of the measurements. While only one measurement of lead in blood or chlopyrifos in dust was needed for a dependable estimate of an individual's average level, three to eight measurements were needed for most other compound/exposure medium combinations because of considerable temporal variability. Measurements in biological fluids and dust were generally more consistent than those in indoor air. The significant covariates in the full models preferentially reduced the between-person variance component. Since the regression models explained only 1-37% of the within-person variance, the questionnaires in this study provided only modest insight into the factors responsible for the temporal variability in the contaminant levels.

AN - 68576440; 15982694 AB - Biologically rational regulatory policies with regards to developmental toxicity are often based on the extrapolation of standard laboratory rodent bioassay results to the human population. Significantly contributing to the difficulty of this task is the possibility that general toxic effects on the maternal organism may affect the developing conceptus. This review examines maternal factors which may bear directly or indirectly upon developmental outcome, with emphasis on those of greatest relevance to the hazard assessment process. Standard teratology testing protocols call for top dosage levels that induce overt maternal toxicity, and the developmental effects of this toxicity (both alone, and with concurrent embryo/fetal insult) continue to present regulators with considerable interpretive difficulties. In response to these problems, there have been both research and literature review efforts dealing with the relationship of maternal and developmental toxicity. Maternally mediated developmental toxicity occurs with a number of agents, and toxicant-induced alterations in maternal physiology may affect the conceptus at dosages not causing overt maternal toxicity. Relevant studies are reviewed here, and suggestions for avenues of future research are offered including the identification of any syndromes of developmental effects occurring at maternally toxic levels irrespective of the causative agent, and experimental approaches for the characterization of maternal toxicity.

AN - 68575648; 15979669 AB - There is an increased interest in utilizing mechanistic data in support of the cancer risk assessment process for ionizing radiation and environmental chemical exposures. In this regard, the use of biologically based dose-response models is particularly advocated. The aim is to provide an enhanced basis for describing the nature of the dose-response curve for induced tumors at low levels of exposure. Cellular responses that might influence the nature of the dose-response curve at low exposures are understandably receiving attention. These responses (bystander effects, genomic instability, and adaptive responses) have been studied most extensively for radiation exposures. The former two could result in an enhancement of the tumor response at low doses and the latter could lead to a reduced response compared to that predicted by a linear extrapolation from high dose responses. Bystander responses, whereby cells other than those directly traversed by radiation tracks are damaged, can alter the concept of target cell population per unit dose. Similarly, induced genomic instability can alter the concept of total response to an exposure. There appears to be a role for oxidative damage and cellular signaling in the etiology of these cellular responses. The adaptive response appears to be inducible at very low doses of radiation or of some chemicals and reduces the cellular response to a larger challenge dose. It is currently unclear how these cellular toxic responses might be involved in tumor formation, if indeed they are. In addition, it is not known how widespread they are as regards inducing agents. Thus, their impact on low dose cancer risk remains to be established.

AN - 68575340; 15993452 AB - The World Health Organization's (WHO's) International Program for Chemical Safety has developed a framework for performing risk assessments that integrate the assessment of risks to human health and risks to nonhuman organisms and ecosystems. The WHO's framework recognizes that stakeholders and risk managers have their own processes that are parallel to the scientific process of risk assessment and may interact with the risk assessment at various points, depending on the context. Integration of health and ecology provides consistent expressions of assessment results, incorporates the interdependence of humans and the environment, uses sentinel organisms, and improves the efficiency and quality of assessments relative to independent human health and ecological risk assessments. The advantage of the framework to toxicologists lies in the opportunity to use understanding of toxicokinetics and toxicodynamics to inform the integrated assessment of all exposed species.

AN - 68555688; 16140616 AB - Cancer risk assessment methods currently assume that children and adults are equally susceptible to exposure to chemicals. We reviewed available scientific literature to determine whether this was scientifically supported. We identified more than 50 chemicals causing cancer after perinatal exposure. Human data are extremely limited, with radiation exposures showing increased early susceptibility at some tumor sites. Twenty-seven rodent studies for 18 chemicals had sufficient data after postnatal and adult exposures to quantitatively estimate potential increased susceptibility from early-life exposure, calculated as the ratio of juvenile to adult cancer potencies for three study types: acute dosing, repeated dosing, and lifetime dosing. Twelve of the chemicals act through a mutagenic mode of action. For these, the geometric mean ratio was 11 for lifetime exposures and 8.7 for repeat exposures, with a ratio of 10 for these studies combined. The geometric mean ratio for acute studies is 1.5, which was influenced by tissue-specific results [geometric mean ratios for kidney, leukemia, liver, lymph, mammary, nerve, reticular tissue, thymic lymphoma, and uterus/vagina > 1 (range, 1.6-8.1); forestomach, harderian gland, ovaries, and thyroid < 1 (range, 0.033-0.45)]. Chemicals causing cancer through other modes of action indicate some increased susceptibility from postnatal exposure (geometric mean ratio is 3.4 for lifetime exposure, 2.2 for repeat exposure). Early exposures to compounds with endocrine activity sometimes produce different tumors after exposures at different ages. These analyses suggest increased susceptibility to cancer from early-life exposure, particularly for chemicals acting through a mutagenic mode of action.

Last updated - 2017-01-18 ER - TY - JOUR T1 - Aging and the environment: a research framework. AN - 68553845; 16140638 AB - The rapid growth in the number of older Americans has many implications for public health, including the need to better understand the risks posed to older adults by environmental exposures. Biologic capacity declines with normal aging; this may be exacerbated in individuals with pre-existing health conditions. This decline can result in compromised pharmacokinetic and pharmacodynamic responses to environmental exposures encountered in daily activities. In recognition of this issue, the U.S. Environmental Protection Agency (EPA) is developing a research agenda on the environment and older adults. The U.S. EPA proposes to apply an environmental public health paradigm to better understand the relationships between external pollution sources --> human exposures --> internal dose --> early biologic effect --> adverse health effects for older adults. The initial challenge will be using information about aging-related changes in exposure, pharmacokinetic, and pharmacodynamic factors to identify susceptible subgroups within the diverse population of older adults. These changes may interact with specific diseases of aging or medications used to treat these conditions. Constructs such as "frailty" may help to capture some of the diversity in the older adult population. Data are needed regarding a) behavior/activity patterns and exposure to the pollutants in the microenvironments of older adults; b) changes in absorption, distribution, metabolism, and excretion with aging; c) alterations in reserve capacity that alter the body's ability to compensate for the effects of environmental exposures; and d) strategies for effective communication of risk and risk reduction methods to older individuals and communities. This article summarizes the U.S. EPA's development of a framework to address and prioritize the exposure, health effects, and risk communications concerns for the U.S. EPA's evolving research program on older adults as a susceptible subpopulation.

AN - 68480424; 16045963 AB - A comprehensive model describing monochloramine loss in the presence of natural organic matter (NOM) is presented. The model incorporates simultaneous monochloramine autodecomposition and reaction pathways resulting in NOM oxidation. These competing pathways were resolved numerically using an iterative process evaluating hypothesized reactions describing NOM oxidation by monochloramine under various experimental conditions. The reaction of monochloramine with NOM was described as biphasic using four NOM specific reaction parameters. NOM pathway 1 involves a direct reaction of monochloramine with NOM (k(doc1) = 1.05 x 10(4)-3.45 x 10(4) M(-1) h(-1)). NOM pathway 2 is slower in terms of monochloramine loss and attributable to free chlorine (HOCl) derived from monochloramine hydrolysis (k(doc2) = 5.72 x 10(5)-6.98 x 10(5) M(-1) h(-1)), which accounted for the majority of monochloramine loss. Also, the free chlorine reactive site fraction in the NOM structure was found to correlate to specific ultraviolet absorbance at 280 nm (SUVA280). Modeling monochloramine loss allowed for insight into disinfectant reaction pathways involving NOM oxidation. This knowledge is of value in assessing monochloramine stability in distribution systems and reaction pathways leading to disinfection by-product (DBP) formation.

AN - 68460233; 16091614 AB - Particulate matter in urban rivers transports a significant fraction of pollutants, changes rapidly during storm events, and is difficult to characterize. In this study, the physical speciation of trace metals and organic C in an urban river and upstream headwaters site in Torrington, CT, were measured during a winter rain-on-snow event. In addition, a selective fractionation scheme, using membrane and tangential-flow ultrafiltration methods to separate suspended particulate matter into sand, silt, clay, and colloid fractions, was evaluated based on the appropriateness of the chosen size categories. During peak runoff at the urban river site, total-recoverable concentrations of the metals Cu and Pb increased 6- and 13-fold to 16.9 and 9.5 microg L(-1), respectively, compared with baseflow concentrations. Concentrations of Cu and Pb reached only 0.9 and 0.86 microg L(-1) at the headwaters site. For the measured storm event, the majority of metals were transported by the urban river in association with coarse silt (20-80 microm particle diam.) during peak runoff. During peak runoff at the urban site, organic C associated with the large colloid fraction (0.1-1.0 microm) increased from 5% (at baseflow) to 54% of the total C in transport, whereas dissolved organic C and that associated with smaller colloids decreased from 91.5% (at baseflow) to 41% of the total. Other elements that were monitored as part of the study were Na, K, Ca, Mg, Fe, Mn, Al, Cd, Cl-, NO3(-), and SO4(2-). The chosen fractionation scheme was useful to characterize pollutant transport during this event, but further testing should be undertaken to determine the most appropriate size range categories, and to ensure that the sizes measured are comparable to those used in other studies.

AN - 68449539; 16077927 AB - The molecular mechanisms mediating arsenic-induced carcinogenesis are not well understood. The role of confounding factors such as ultraviolet radiation (UV), add another level of complexity to the study of arsenic carcinogenesis and the cancer-risk assessment on humans. We hypothesized that arsenicals are capable of overriding the growth arrest caused by UV treatment and may lead to selective proliferation. To test this hypothesis, a primary normal human epidermal keratinocyte (NHEK) cell culture model was used. One group was pre-exposed to UVB (100 mJ/cm(2)) that arrested a majority ( approximately 95%) of cells in G0/G1 (+UV) and a second group was not exposed to UV (-UV). Treatment of cells with various arsenicals [0-12 microM of inorganic arsenite (iAs), 0-2 microM of methyl oxoarsine (MMAs III) and 0-3 microM of iododimethyl arsine (DMAs III)] indicated a concentration-dependent increase in proliferation at 24 h in the order of DMAs III > MMAs III > iAs. Flow-cytometric analyses revealed differential effects on cell cycle distribution. Analysis of a battery of cell cycle proteins (cyclin D1, cdk5, PCNA, cdc25A and cdc25C) indicated exposure-specific differential expression profiles. Increased activation of JNK phosphorylation (5-10-fold) in the +UV group and the synergistic increase with methyl arsenicals suggested that JNK might be involved in cell survival and proliferative signaling. Induction of EGF levels and increased phosphorylation of the EGF receptor by arsenicals (+UV) suggested that the EGF signaling pathway might mediate arsenical-induced cell proliferation of NHEK cells. Differential activation of ERK1/2 by arsenicals (+/-UV) suggested that EGF-mediated cell proliferation by arsenicals in UV-treated NHEK cells may not involve ERK activation. Taken together, the data suggest that both UV exposure and methylation status of the arsenicals dictate the participation of key cell cycle proteins and related signaling events in arsenical-induced cell proliferation.

AN - 68031853; 15998591 AB - During the Balkan conflicts, in 1995 and 1999, depleted uranium (DU) rounds were employed and were left in the battlefield. Health concern is related to the risk arising from contamination of the environment with DU penetrators and dust. In order to evaluate the impact of DU on the environment and population in Serbia and Montenegro, radiological surveys of DU in water, air and biological samples were carried out over the period 27 October-5 November 2001. The uranium isotopic concentrations in biological samples collected in Serbia and Montenegro, mainly lichens and barks, were found to be in the range of 0.67-704 Bqkg(-1) for (238)U, 0.48-93.9 Bqkg(-1) for (234)U and 0.02-12.2 Bqkg(-1) for (235)U, showing uranium levels to be higher than in the samples collected at the control sites. Moreover, (236)U was detectable in some of the samples. The isotopic ratios of (234)U/(238)U showed DU to be detectable in many biological samples at all examined sites, especially in Montenegro, indicating widespread ground-surface DU contamination, albeit at very low level. The uranium isotopic concentrations in air obtained from the air filter samples collected in Serbia and Montenegro were found to be in the range of 1.99-42.1 microBqm(-3) for (238)U, 0.96-38.0 microBqm(-3) for (234)U, and 0.05-1.83 microBqm(-3) for (235)U, being in the typical range of natural uranium values. Thus said, most of the air samples are DU positive, this fact agreeing well with the widespread DU contamination detected in the biological samples. The uranium concentrations in water samples collected in Serbia and Montenegro were found to be in the range of 0.40-21.9 mBql(-1) for (238)U, 0.27-28.1 mBql(-1) for (234)U, and 0.01-0.88 mBql(-1) for (235)U, these values being much lower than those in mineral water found in central Italy and below the WHO guideline for drinking water. From a radiotoxicological point of view, at this moment there is no significant radiological risk related to these investigated sites in terms of possible DU contamination of water, air and/or plants.

The removal of carbonates from sediments is achieved with acidification, which causes the dissolution and decomposition of carbonates with accompanying effervescence. This effervescence, or the lack of it, is commonly used as an indicator for the presence or absence of carbonates. We have found that the lack of effervescence endpoint used with the direct acidification method (adding aliquots of acid to samples) is not a reliable indicator for complete removal of carbonates from sediment samples. The ineffectiveness of the lack of effervescence endpoint, we believe, is caused by the presence of carbonates with dissolution rates much slower than those of calcite, resulting in much slower rates of visible effervescence. We propose and demonstrate a method for determining the amount of acid required for complete elimination of all carbonates using Lake Michigan (USA) sediment samples. Based on our experiences with the lack of effervescence endpoint, we recommend that in any scheme for analysis of OC and/or BC, a minimum of two samples be treated with three different levels of acidification, with the lowest level being the same as that planned for all the OC and/or BC analyses. There can be no significant differences among the OC and BC contents measured using the three different levels of acidification.

This assumption is used to ensure protection of the public health in the absence of relevant dose-response data. A theoretical justification for the assumption has been provided by the argument that low dose linearity is expected when an exogenous agent adds to an ongoing endogenous process. Here, we use computational modeling to evaluate (1) how two biological adaptive processes, induction of DNA repair and cell cycle checkpoint control, may affect the shapes of dose-response curves for DNA-damaging carcinogens and (2) how the resulting dose-response behaviors may vary within a population. Each model incorporating an adaptive process was capable of generating not only monotonic dose-responses but also nonmonotonic (J-shaped) and threshold responses. Monte Carlo analysis suggested that all these dose-response behaviors could coexist within a population, as the spectrum of qualitative differences arose from quantitative changes in parameter values. While this analysis is largely theoretical, it suggests that (a) accurate prediction of the qualitative form of the dose-response requires a quantitative understanding of the mechanism, (b) significant uncertainty is associated with human health risk prediction in the absence of such quantitative understanding and (c) a stronger experimental and regulatory focus on biological mechanisms and interindividual variability would allow flexibility in regulatory treatment of environmental carcinogens without compromising human health.

EPA recruited 25 LEVs in 2002 and measured emissions on a chassis dynamometer using the cold-start urban dynamometer driving schedule of the Federal Test Procedure. The emissions measured included regulated pollutants, particulate matter, speciated hydrocarbon compounds, and carbonyl compounds. The results provided a comparison of emissions from real-world LEVs with emission standards for criteria and air-toxic compounds. Emission measurements indicated that a portion of the in-use fleet tested exceeded standards for the criteria gases. Real-time regulated and speciated hydrocarbon measurements demonstrated that the majority of emissions occurred during the initial phases of the cold-start portion of the urban dynamometer driving schedule. Overall, the study provided updated emission factor data for real-world, in-use operation of LEVs for improved emissions modeling and mobile source inventory development.

To comply with these regulatory requirements, it is increasingly important to implement state-of-the-art NOx control technologies on coal-fired utility boilers. This paper reviews NOx control options for these boilers. It discusses the established commercial primary and secondary control technologies and examines what is being done to use them more effectively. Furthermore, the paper discusses recent developments in NOx controls. The popular primary control technologies in use in the United States are low-NOx burners and overfire air. Data reflect that average NOx reductions for specific primary controls have ranged from 35% to 63% from 1995 emissions levels. The secondary NOx control technologies applied on U.S. coal-fired utility boilers include reburning, selective noncatalytic reduction (SNCR), and selective catalytic reduction (SCR). Thirty-six U.S. coal-fired utility boilers have installed SNCR, and reported NOx reductions achieved at these applications ranged from 15% to 66%. Recently, SCR has been installed at 150 U.S. coal-fired utility boilers. Data on the performance of 20 SCR systems operating in the United States with low-NOx emissions reflect that in 2003, these units achieved NOx emission rates between 0.04 and 0.07 lb/106 Btu.

To this end, we have developed a method that is cost effective, easy to perform, and accurate. We performed a simple polymerase chain reaction/restriction fragment length polymorphism (PCR/RFLP) analysis on multiple members of species known to negatively influence the indoor environment. The genera analyzed were Stachybotrys, Penicillium, Aspergillus, and Cladosporium. Each organism underwent PCR with universal primers that amplified ribosomal sequences generating products from 550 to 600 bp followed by enzymatic digestion with EcoRI, HaeIII, MspI, and HinfI. Our results show that using this combination of restriction enzymes enables the identification of these fungal organisms at the species level.

Dissolved inorganic nitrogen ([image]) and o-phosphate ([image]) are the main forms of N and P that are readily bio- available for plant growth in waters and these have a Redfield atomic ratio of N:P = 16:1 (i.e. aquatic plants absorb N and P in the average ratio of 16 atoms of N to 1 atom of P). Graphs are prepared for (i) DIN vs salinity and (ii) o-phosphate vs salinity with the vertical scales for DIN and o-phosphate set at a ratio of N:P = 16:1; when these graphs are overlaid on each other then the lowermost trendline denotes the limiting nutrient for plant/algal growth - at any salinity. The graphs also indicate the extent by which one or other of the nutrients is limiting - at any salinity. Furthermore, if there is a transition from P to N limitation somewhere along the salinity gradient, then this occurs at the salinity where the trendlines intersect. The concept was applied to three estuaries in the southeast of Ireland and the results show that, in all of these circumstances, P is the limiting nutrient throughout - except for the higher salinities (i.e. salinities 30ppt), where either (i) N and P may become equally limiting at salinity 35ppt or (ii) N may become limiting at salinity 30ppt.

Fortunately, great strides have been made in the development of methods of species characterization and in their application to the analysis of particulates and mixtures of solid phases in physics, analytical chemistry, and materials science. This manuscript highlights a selection of the analytical methods available today offering the greatest promise, briefly describes the fundamental processes involved, examines their limitations, points to how they have been used in the environmental and geochemical literature, and offers some suggested research directions in the hope of stimulating further investigation into the application of these powerful tools to the problems outlined above.

To be eaten, prey must co-occur spatially and temporally with the predator (distribution), the predator must recognize the prey as potential food and successfully capture it (behavior), and the predator must have a mouth large enough to ingest its target (morphology). We quantified the cumulative effect of these three factors on clupeid prey availability to both largemouth bass Micropterus salmoides and striped bass Morone saxatilis in Smith Mountain Lake, Virginia. As expected, morphological constraints were more severe for small predators. Alewives Alosa pseudoharengus were morphologically more available than gizzard shad Dorosoma cepedianum. Incongruent spatial distributions, the result of lake stratification, prevented striped bass from feeding on gizzard shad during summer and limited largemouth bass consumption of alewives. For unknown behavioral reasons, largemouth bass and striped bass consumed only clupeids between 40 and 160 mm total length. For largemouth bass, the available supply of alewives was equivalent to demand and that of gizzard shad exceeded consumption by 53%. For striped bass, the available supply of gizzard shad surpassed consumption by 26% and that of alewives was 4% greater than consumption. Annual consumption by all clupeid predators, including largemouth bass and smallmouth bass Micropterus dolomieu, striped bass, walleye Sander vitreus, flathead catfish Pylodictis olivaris, channel catfish Ictalurus punctatus, white catfish Ameiurus catus, and crappies Pomoxis spp., was 94% of the total available clupeid supply. Our analysis indicates that increased predation on the clupeid forage base of Smith Mountain Lake would lead to decreased prey production and produce prey shortages for piscivores that are dependent on this food resource.

This paper describes a combined hydrologic simulation and landscape design model designed to prioritize sites for wetlands restoration, where the objective is to maximize the amount of nutrients in non-point-source runoff attenuated in the restored wetlands. Targeted site selection in four small watersheds in the Central Valley resulted in predicted levels of nitrogen attenuation two to eight times greater than that from maximizing wetland area without consideration of the location of the restoration sites.

Separation of Chapel Hill PM 10 into fine and coarse size particles revealed that the main proinflammatory response (TNF, IL-6, COX-2) in AM was driven by material present in the coarse PM, containing 90-95% of the stimulatory material in PM10. The particles did not affect expression of hemoxygenase-1 (HO-1), a sensitive marker of oxidant stress. Primary cultures of normal human bronchial epithelial cells (NHBE) also responded to the coarse fraction with higher levels of IL-8 and COX-2, than induced by fine or ultrafine PM. All size PM induced oxidant stress in NHBE, while fine PM induced the highest levels of HO-1 expression. The production of cytokines in AM by both coarse and fine particles was blocked by the toll like receptor 4 (TLR4) antagonist E5531 involved in the recognition of LPS and Gram negative bacteria. The NHBE were found to recognize coarse and fine PM through TLR2, a receptor with preference for recognition of Gram positive bacteria. Compared to ambient PM, diesel PM induced only a minimal cytokine response in both AM and NHBE. Instead, diesel suppressed LPS-induced TNF and IL-8 release in AM. Both coarse and fine ambient air PM were also found to inhibit LPS-induced TNF release while silica, volcanic ash or carbon black had no inhibitory effect. Diesel particles did not affect cytokine mRNA induction nor protein accumulation but interfered with the release of cytokine from the cells. Ambient coarse and fine PM, on the other hand, inhibited both mRNA induction and protein production. Exposure to coarse and fine PM decreased the expression of TLR4 in the macrophages. Particle-induced decrease in TLR4 and hyporesponsiveness to LPS may be related to LPS tolerance induced by low levels of LPS.

A primer and application of the stable isotopes, super(18)O and super(2)H, are discussed for riparian wetland restoration areas among an agricultural landscape in southwestern Ohio. Conventional piezometric measurements were ambiguous in identifying groundwater mounding across a transect which includes numerous agricultural tile drains. Instead evaporative potential data represented by delta super(18)O values indicated a well delineated zone for prospective constructed wetlands. All successful constructed wetland areas thus far at Shaker Trace are represented by ground water with depleted delta super(18)O values below -9.0ppt VSMOW. Such areas of sustainable ground water inflow could either be due to perched units at depth or simply the result of an increased flow gradient.

Based on the fate of iron in airway epithelial cells, we postulated that divalent metal transporter-1 (DMT1) participates in detoxification of metal associated with air pollution particles. Homozygous Belgrade rats, which are functionally deficient in DMT1, exhibited diminished metal transport from the lower respiratory tract and greater lung injury than control littermates when exposed to oil fly ash. Preexposure of normal rats to iron in vivo increased expression of the isoform of DMT1 protein that lacked an iron-response element (-IRE), accelerated metal transport out of the lung, and decreased injury after particle exposure. In contrast, normal rats preexposed to vanadium showed less expression of the -IRE isoform of DMT1, decreased metal transport, and greater pulmonary injury after particle instillation. Respiratory epithelial cells in culture gave similar results. Also, DMT1 mRNA and protein expression for the -IRE isoform increased or decreased in these cells when exposed to iron or vanadium, respectively. These results thus demonstrate for the first time a primary role for DMT1 in lung metal transport and detoxification.

This paper provides an overview of the benefits of methane reduction and the goals and objectives of the Methane to Markets Partnership. In addition, it includes a discussion of the available opportunities and technologies for methane recovery and use in the coal, oil and gas, and landfill sectors. The paper concludes with some insights into the US government's involvement in the initiative and the methane emission reduction potential of the Partnership.

Because the pathogenesis of many of these diseases remains unknown, we must consider that environmental factors may play a causal role. This review provides an overview of the epidemiologic evidence for environmental etiologies for neurodegenerative diseases such as Alzheimer disease, Parkinson disease, parkinsonian syndromes (multiple system atrophy and progressive supranuclear palsy), and amyotrophic lateral sclerosis. Epidemiologic evidence for an association between environmental agents' exposure and neurodegenerative diseases is not conclusive. However, there are indications that there may be causal links, and the need for more research is obvious.

Low levels of folate have been associated with several forms of cancer, including colon cancer. Aberrant crypt foci (ACF), identified as putative precursor lesions in the development of colon cancer, have been induced by the drinking water disinfection by-product, tribromomethane (TBM). To investigate whether ACF induced by TBM could be promoted by a diet devoid of dietary folate, male F344/N rats were exposed to 500 mg/l of TBM in drinking water and fed either a normal or no folate diet (NFD) for 26 weeks. At the conclusion of the study, colons were excised and examined for ACF. Rats exposed to TBM and fed a NFD, evident by significantly reduced serum folate concentrations and elevated serum homocysteine levels, had significant increases of ACF when compared to rats exposed to TBM and fed a normal diet. This study highlights the important role that diet, especially folate intake, represents in protecting the colon against TBM-induced ACF.

I. The yellow-bellied glider (Petaurus australis) AN - 17475988; 6668577 AB - Generalised linear modelling (logistic regression) was used to predict habitat suitability for the yellow-bellied glider (Petaurus australis) from data collected from 620 sites throughout southern Queensland, Australia. Of 42 potential explanatory biotic and abiotic variables, 12 were selected in the final model including an index describing bark characteristics of the overstorey, five climatic variables, three topographic/lithological variables, two landscape metrics and one survey covariate. The predictive capacity of the final model was evaluated using Receiver Operating Characteristic curves and an independent validation dataset (ROC = 0.75; n = 180). Of the extant forest and woodlands of the southern Queensland study region, the interpolated model predicted that approximately 19% was yellow-bellied glider habitat. The majority of predicted habitat occurred within public-owned forests, which are managed under a set of prescribed standards in a Code of Practice for commercial forest management. An important issue for conservation management of the yellow-bellied glider will be management of habitat on privately owned land, which incorporates over 27% of potential glider habitat.

An essential step is to find and understand the common parameters that closely relate to leaching losses across a wide range of land-use systems. The overall objective of this study was to relate NO sub(3) super(-) leaching losses to various properties across soil types and land-use systems. We chose two locations in southeastern Oklahoma with different soil types. The land-use systems were old-field (abandoned grassland), forest and cultivated arable crop. Parameters determined were soil biomass C, biomass N, total C, total N, extractable mineral N, pH, moisture, CO sub(2) emission and lysimeter- drained water NO sub(3) super(-) concentration. Firstly, stepwise multiple linear- regression analyses were performed between biannual NO sub(3) super(-) leaching losses and monthly measured independent variables. Secondly, annual and biannual timescale-independent variables and respective NO sub(3) super(-) leaching losses were used to perform a regression model. Monthly measured parameters explained over 75% of the biannual NO sub(3) super(-) leaching losses, but often with different explanatory variables. Land use was the dominant parameter on monthly models, while soil total C, total C/N ratio, extractable NH sub(4) super(+) and NO sub(3) super(-) concentrations and water flux were the most frequently included parameters. When annual- and biannual-mean parameter values were used in regression, respective NO sub(3) super(-) leaching losses were explained by somewhat similar parameters to monthly models. Together, these parameters explained only 63, 53 and 44% of the total variation in NO sub(3) super(-) leaching loss for the first, second and biannual period, respectively. These models explained a consistently lower amount of variation than the monthly models. Additionally, more than 70% of the total variation could be explained by NO sub(3) super(-) concentration and the tested soil- type related parameters. Results from this study revealed that annual and biannual trends of NO sub(3) super(-) leaching losses across land-use systems can be explained by a number of parameters collectively rather than a single parameter. Thus, there is no single parameter that can be used to fully predict NO sub(3) super(- ) leaching losses across different land-use systems on a monthly, annual and biannual basis. Additionally, there is no specific month or season for sampling to better predict NO sub(3) super(-) leaching losses across different soil and land- use systems.

VEPs were recorded from visual cortex following stimulation of the eyes and, thus, reflect the function of the afferent visual pathway and, in broad terms, may be indicative of overall brain function. The concentration of TCE in the brain at the time of VEP testing (i.e., momentary brain concentration) was hypothesized to predict the amplitude of the VEP across a range of inhalation concentrations, both during and after exposure. Awake restrained rats were exposed to clean air or TCE in the following combinations of concentration and duration: 500 ppm (4 h), 1000 ppm (4 h), 2000 (2 h), 3000 ppm (1.3 h), 4000 ppm (1 h), and 5000 ppm (0.8 h). VEPs were recorded several times during the exposure session, and afterward for experimental sessions of less than 4 h total duration (i.e., concentrations from 2000 to 5000 ppm). The sample collection time for each VEP was about 1 min. Brain concentrations of TCE were predicted using a physiologically based pharmacokinetic (PBPK) model. VEP waveforms were submitted to spectral analysis, and the amplitude of the largest response component, occurring at twice the temporal stimulation rate (F2), was measured. Exposure to all air concentrations of TCE in the study reduced F2 amplitude. The reduction of F2 amplitude was proportional to momentary brain TCE concentration during and after exposure. A logistical function fit to the combined data from all exposure conditions described a statistically significant relationship with 95% confidence limits between brain TCE concentration and F2 amplitude. The results support the hypothesis that momentary brain concentration of TCE is an appropriate dose metric to describe the effects of acute TCE inhalation exposure on rat VEPs. The combination of the PBPK model predicting brain TCE concentration from the exposure conditions with the logistical function predicting F2 amplitude from the brain TCE concentration constitute a quantitative exposure-dose-response model describing an acute change in neurological function following exposure to an important hazardous air pollutant.

Enhanced coagulation modification options include: (1) increased ferric chloride dose, (2) addition of an acid dose, and (3) a combination of the individual options. Arsenic removal is described by adsorption to hydrous ferric oxide with a surface complexation model and subsequent removal through sedimentation and filtration. The least-cost modification for reliably satisfying the arsenic regulation is determined using an optimization algorithm that explicitly includes variability and uncertainty. The ferric chloride only modification is always the least-cost treatment modification. The ferric chloride and acid modification could be the least-cost option when considering waste handling processes due to a tradeoff between modification cost and sludge production. By inclusion of variability and uncertainty, the relative importance of individual parameter distributions for determining whether the arsenic regulation is reliably satisfied is assessed. Influent arsenic concentration variability is always critical, while variability in the influent pH and sulfate concentrations and uncertainty in the filter removal efficiency and equilibrium adsorption constant for the identical with Fe super(s)OHCa super(2+) surface species are critical or important, depending on influent conditions.

Our goal was to describe wetland aquatic habitat patterns and the natural factors that organize them as a step towards developing habitat assessment schemes and identifying experimental design elements for future synoptic surveys. We analyzed data on aquatic vegetation structure, water chemistry, and water movement (inferred from gypsum plug dissolution) in relation to hydrology and morphology in inundated segments of ten relatively un-impacted coastal marshes of western Lake Superior. Spatial differences in aquatic habitat within wetlands were as large or larger than differences among wetlands, and habitat patterns were strongly associated with morphology and hydrology. Back-bay segments tended to have greater vegetation cover and structural complexity and lower levels of water movement, and they were prone to high water temperatures and low dissolved oxygen levels in wetlands having little seiche activity. Increasing seiche inputs tended to homogenize habitat elements among wetland segments, while increasing tributary inputs tended to increase spatial variability. Patterns in emergent vegetation differed from patterns in submerged/floating vegetation, and different assessment metrics may be needed for different plant zones. Segment-scale sampling schemes like those used in this study have the potential to elucidate habitat patterns within inundated portions of wetlands with a reasonable level of effort. Human impacts on coastal wetland fish habitat must be interpreted in the context of natural spatial heterogeneity as structured by wetland morphology and magnitude of seiche and tributary inputs.

To address this issue, an isoprene/NO sub(x)/air mixture was irradiated in a flow reactor smog chamber in both the absence and presence of SO sub(2) to measure the SOA yield of isoprene and to establish whether the two 2-methyl tetrols and 2-methylglyceric acid are present in isoprene SOA and could serve as SOA indicator compounds. In the absence of SO sub(2), the SOA yield of 0.002 was low, as expected, although uncertain because the SOA concentration was near chamber background levels. However, in the presence of SO sub(2), the SOA yield increased significantly to 0.028. Analysis of the trimethylsilyl derivatives of the SOA samples by gas chromatography/mass spectrometry showed chamber concentrations of the two 2- methyl tetrols totaling 0.1 mu g m super(-3) and a 2-methylglyceric acid concentration of 0.4 mu g m super(-3) in the absence of SO sub(2), with the levels increasing significantly to 6.3 mu g m super(-3) and 1.2 mu g m super(-3), respectively, when SO sub(2) was added. The laboratory data suggest that these compounds are possible indicator compounds for isoprene SOA and that the presence of SO sub(2) enhances significantly SOA formation from isoprene photooxidation, with acid- catalyzed reactions possibly playing a major role. The importance of these findings was supported by the detection of the two 2-methyl tetrols and 2- methylglyceric acid in summertime ambient PM sub(2.5) samples collected at three locations in the eastern United States. However, additional mechanistic studies are required to predict the contributions of the SO sub(2)-assisted isoprene SOA formation to ambient PM sub(2.5) concentrations.

Closed form solutions expressed as convolution integrals of impulse response and unit step response functions are derived for channel flow and stream-aquifer interactions. The solutions, obtained using Laplace transforms, relate channel reach discharge, stream-aquifer exchange rates, and associated flow volumes to hydrologic processes and regulatory and management control measures. Channel flow is modeled using a simple mass balance equation and the Muskingum linear storage relationship, and groundwater flow is approximated by a linearized representation of the one-dimensional Boussinesq equation. Within a given channel reach, the aquifer is assumed to be homogeneous, separated from the channel by a semipervious layer, and with a time-variable prescribed head or no- flow boundary condition at a finite distance normal to the channel flow direction. Discrete-time unit response functions are derived for arbitrary channel inflow hydrographs and other system's excitations, which extend the utility of the model to a wider spectrum of water management problems. Although the closed-form solutions are based on simplifying assumptions which may limit the utility of the solutions, applications to example flow scenarios nonetheless illustrate the robustness of the solutions to a variety of applications such as the bank storage problem, effect of drought periods, and groundwater-surface water interactions in the presence of water management controls.

Two different types of experiments were completed; the first examined possible artifacts from oils used in personal environmental monitor (PEM) impactor plates, and the second examined artifacts from microenvironmental sampling using different sampling media combinations (quartz, Teflon, XAD denuder, and electrostatic precipitator). The effectiveness of front and backup filters was evaluated for most sampling configurations. Mean total carbon concentrations from sampling configurations using impactor oils were not statistically different from the control case (using a sharp cut cyclone). Three microenvironments were tested (kitchen, library, and ambient); carbon concentrations were highest in the kitchen using a front quartz filter (mean OC of 16.4 mu g m super(-3)). The lowest front quartz filter concentrations were measured in the library using XAD denuders (mean OC of 3.6 mu g m super(-3)). Denuder removal efficiencies (average of 82% for total carbon) were lower compared with previous ambient studies and may indicate that indoor sources influenced denuder efficiency during sample collection. The highest carbon concentrations from backup quartz filters were measured using the Teflon-quartz combination.

The model simulated daily growth, mortality, movement and spawning of individuals within a reach of stream. Juvenile and adult growth was based on consumption bioenergetics of benthic macroinvertebrate prey; benthic macroinvertebrate densities were a function of flow, season, and habitat quality. We based mortality rates of individual sculpin on their condition. Fish movement was determined by a growth maximization rule. We adjusted selected parameters to calibrate the model for a sculpin population in a southern Appalachian stream, in terms of adult and juvenile abundance and mean adult weight and length. Sensitivity and correlation analysis of the calibrated model suggested that this population was regulated by overwinter density-dependence among juveniles and adults.

The rising in levels of PBDEs in tissues in wildlife species and in human milk and plasma samples over the past several years have raised concerns about possible health effects. Recently, we showed that the PBDE mixture, DE-71, delayed puberty and suppressed the growth of androgen-dependent tissues in male Wistar rat following a peri-pubertal exposure. These effects suggested that DE-71 may be either inducing steroid hormone metabolism or acting as an androgen receptor (AR) antagonist. To elucidate the potential anti-androgenic effects of this mixture, we evaluated DE-71 in several in vivo assays, which are responsive to alterations in androgen activity. In a pubertal exposure study designed to further evaluate the delay in preputial separation (PPS), we observed a dose-dependent delay in PPS with 60 and 120 mg/kg/day of DE-71 (4 and 5 days) and a corresponding suppression of ventral prostate (VP) and seminal vesicle growth at both doses. Adult males exposed to 60 mg/kg DE-71 for 3 days resulted in a significant increase in luteinizing hormone and a non-significant increase in testosterone, androstenedione and estrone. DE-71 also tested positive for anti-androgenic activity in an immature rat Hershberger assay, with decreases in mean VP and seminal vesicle weight following doses of 30-240 mg/kg. DE-71 and the individual BDE congeners which comprise the mixture (BDE-47, -99, -100, -153, -154) were also evaluated in vitro. First, AR binding was evaluated in a competitive binding assay using rat VP cytosol. In addition, we evaluated gene activation in a transcriptional activation assay using the MDA-kb2 cell line which contains an endogenous human AR and a transfected luciferase reporter. DE-71 and BDE-100 (2, 4, 6-pentaBDE) both inhibited AR binding, with IC50s of approximately 5 mu M. In addition, DE-71 and two of the congeners (BDE-100 and BDE-47) inhibited DHT-induced transcriptional activation. The pattern of inhibition shown in the double-reciprocal plot for BDE-100 and the linear slope replot confirmed that the in vitro mechanism is pure competitive inhibition, with a inhibition constant (K sub(i)) of 1 mu M. The delay in puberty in the male rat and decreased growth of androgen-dependent tissues observed previously following exposure to DE-71 were likely due to this inhibition of AR binding by several of the congeners which make up this mixture.

AN - 68608424; 16173598 AB - Arabidopsis thaliana root transcriptome responses to the munition, hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), were assessed using serial analysis of gene expression (SAGE). Sequencing of SAGE libraries from control and RDX-exposed root tissues revealed induction of genes known to respond to a variety of general stresses. Among the highly induced genes were several encoding molecular chaperones and transcription factors as well as vacuolar proteins and peroxidases. Strongly repressed transcripts included ones encoding ribosomal proteins, a cyclophilin, a katanin, and a peroxidase. Comparison of the transcriptional profile for the RDX response to a profile previously described for Arabidopsis roots exposed to trinitrotoluene (TNT) revealed significant differences in the inferred gene expression patterns. This suggests that Arabidopsis employs drastically different mechanisms for coping with these two compounds. With respect to the goal of engineering plants to better tolerate and degrade explosives at contaminated sites, these results suggest that enhancement of different genes and metabolic pathways may be required to deal effectively with each type of explosive. This has ramifications for phytoremediation efforts since many contaminated sites harbor both compounds.

The COPSW is characterized by high pH (8.5-11.5) and high Cr(VI) concentrations in the solid phase (up to 550 mg kg super(-1)) and dissolved phase (3-57 mg L super(-1)). The dominant solid-phase minerals are forsterite (Mg sub(2)SiO sub(4)), brucite (Mg-(OH) sub(2)), and hydrocalumite [Ca sub(4)(Al, Fe) sub(2)(OH) sub(12)X times 6H sub(2)O), X = (OH) sub(2) super(2-), SO sub(4) super(2-), CrO sub(4) super(2-)]. The method utilizes FeSO sub(4) in combination with Na sub(2)S sub(2)O sub(4) to inhibit oxidation and precipitation of the ferrous iron, thereby preventing well and formation clogging. Laboratory batch tests using a 0.05 M FeSO sub(4) + 0.05 M Na sub(2)S sub(2)O sub(4) solution indicated effective treatment of both dissolved and solid-phase Cr(VI). Contrary to treatments with FeSO sub(4) and FeCl sub(2) alone, the combination resulted in both complete removal of Cr(VI) from solution and sustained Fe(II) concentrations in solution after a 24 h period. A field test involving injection of 5700 L of a 0.07 M FeSO sub(4) + 0.07 M Na sub(2)S sub(2)O sub(4) solution into a COPSW saturated zone (pH 11.5) indicated no well and formation clogging during injection. Examination of a core collected 0.46 m from the injection well following injection indicated effective treatment of the solid phase Cr(VI) based on analysis of water, phosphate solution, and high temperature alkaline extracts. The combined reductant solution also imparted a residual treatment capacity to the COPSW allowing for subsequent treatment of dissolved phase Cr(VI); however, dissemination of the iron in the highly alkaline environment appeared to be impeded by the inability to sufficiently lower the pH with distance from the injection well to avoid precipitation of Fe(OH) sub(2) and likely also FeCO sub(3). Injection of a 0.2 M FeSO sub(4) + 0.2 M Na sub(2)S sub(2)O sub(4) solution into another COPSW saturated zone (pH 9) indicated much more effective dissemination of the injected iron.

AN - 68446058; 16076090 AB - The enantiomers of five chiral pesticides of environmental interest, metalaxyl, imazaquin, fonofos (dyfonate), ruelene (cruformate), and dichlorprop, were separated analytically using capillary electrophoresis (CE) with cyclodextrin chiral selectors. For metalaxyl, imazaquin, and fonofos, aqueous slurries of soil samples from two sites in Georgia and one in Ohio were spiked with the racemate of each pesticide at 50-60 mg/L of aqueous phase of the slurry, and CE analyses were performed at various time intervals to determine enantiomer fractions (EF). Metalaxyl underwent enantioselective transformation; in one soil, the half-life of the target active R-(+)-enantiomer was 17 days while that for the S-(-)-enantiomer was 69 days. Transformation occurred more slowly in the other two soils but was still selective for the R-(+)-enantiomer. Imazaquin and fonofos exhibited nonselective enantiomer loss over their 3 months of incubation time; this could have been due to abiotic or nonselective microbial reactions. Ruelene and dichlorprop were transformed selectively in a variety of soils in a previously reported study (7) that showed the influence of environmental changes on the transformation of chiral pollutants in soils; analytical methods used in that study are reported here to further illustrate the application of CE. CE is shown to be a simple, efficient, and inexpensive way to follow the transformation of chiral pesticides in laboratory microcosms where concentrations can be made high enough (25-50 mg/L initial racemate concentration) for detection of residual parent enantiomers during most of the process.

Current plans are to study approximately 100,000 children and their families beginning before birth up to age 21 years. To explore potential biomarkers that could be important measurements in the NCS, we compiled the relevant scientific literature to identify both routine or standardized biological markers as well as new and emerging biological markers. Although the search criteria encouraged examination of factors that influence the breadth of child health and development, attention was primarily focused on exposure, susceptibility, and outcome biomarkers associated with four important child health outcomes: autism and neurobehavioral disorders, injury, cancer, and asthma. The Biomarkers Database was designed to allow users to: (1) search the biomarker records compiled by type of marker (susceptibility, exposure or effect), sampling media (e.g., blood, urine, etc.), and specific marker name; (2) search the citations file; and (3) read the abstract evaluations relative to our search criteria. A searchable, user-friendly database of over 2000 articles was created and is publicly available at: http://cfpub.epa.gov/ncea/cfm /recordisplay.cfm?deid=85844. PubMed was the primary source of references with some additional searches of Toxline, NTIS, and other reference databases. Our initial focus was on review articles, beginning as early as 1996, supplemented with searches of the recent primary research literature from 2001 to 2003. We anticipate this database will have applicability for the NCS as well as other studies of children's environmental health.

We utilized two existing organic matter manipulation sites in western Oregon, USA and Hungary to investigate these linkages. Our questions were: (1) what effect does the quantity and quality of organic matter have on net and gross N processing in mineral soil? and (2) do these effects vary across sites with very different climate, soils, vegetation, and N deposition status? The organic matter manipulations had small if any effects on gross and net N cycling rates. Gross N cycling rates under low N deposition increased with increasing soil C and N, but C:N ratio had no correlation with gross N cycling rates. Soil ammonium concentrations under high N deposition, however, were higher in the organic matter manipulation plots without roots and lower in plots with double litter, indicating a tree root effect and a litter immobilization effect, respectively, but did not differ significantly under low N deposition. Net ammonium production was lowest in the litter removal and root removal plots and highest in the litter addition plots at both sites. Gross and net N cycling rates and mineral nitrogen pool sizes were generally higher under higher N deposition and lower C:N ratio soil, which was consistent with past studies over gradients of N deposition. By looking at organic matter manipulations in two very different sites we gained some insight into the role that C:N ratio as well as total C and total N have in controlling N and C cycling in forest soils.

AN - 69071497; 16418903 AB - The Catskill/Delaware reservoirs supply 90% of New York City's drinking water. The City has implemented a series of watershed protection measures, including land acquisition, aimed at preserving water quality in the Catskill/Delaware watersheds. The objective of this study was to examine how relationships between landscape and surface water measurements change between years. Thirty-two drainage areas delineated from surface water sample points (total nitrogen, total phosphorus, and fecal coliform bacteria concentrations) were used in step-wise regression analyses to test landscape and surface-water quality relationships. Two measurements of land use, percent agriculture and percent urban development, were positively related to water quality and consistently present in all regression models. Together these two land uses explained 25 to 75% of the regression model variation. However, the contribution of agriculture to water quality condition showed a decreasing trend with time as overall agricultural land cover decreased. Results from this study demonstrate that relationships between land cover and surface water concentrations of total nitrogen, total phosphorus, and fecal coliform bacteria counts over a large area can be evaluated using a relatively simple geographic information system method. Land managers may find this method useful for targeting resources in relation to a particular water quality concern, focusing best management efforts, and maximizing benefits to water quality with minimal costs.

The sets of BSAFs, when plotted against each other, in log-log space, formed linear relationships and demonstrated that the relative scaling or ranking of the individual BSAFs within a set are consistent, if not the same, across ecosystems. This behavior holds for chemicals that either are, or are not, metabolized by fish. These results demonstrate that sets of BSAF values can differ but with parallel shifts in magnitude between ecosystems (for example, all of the BSAFs in the set are uniformly larger in one ecosystem, while in another they all are uniformly smaller) in response to underlying differences in ecosystem conditions and parameters such as trophic level, diet of the organisms, and distribution of the chemical between the sediment and water column.

AN - 68444598; 16079086 AB - Examining the influence of environmental exposures on various health indices is a critical component of the planned National Children's Study (NCS). An ideal strategy for the exposure monitoring component of the NCS is to measure indoor and outdoor concentrations and personal exposures of children to a variety of pollutants, including ambient particulate and gaseous pollutants, biologic agents, persistent organics, nonpersistent organics (e.g., pesticides), inorganic chemicals (e.g., metals), and others. However, because of the large sample size of the study (approximately 100,000 children), it is not feasible to assess every possible exposure of each child. We envision that cost-effective strategies for gathering the necessary exposure-related information with minimum burden to participants, such as broad administration of product-use questionnaires and diaries, would likely be considered in designing the exposure component of the NCS. In general a biologic (e.g., blood, urine, hair, saliva) measure could be the dosimeter of choice for many of the persistent and for some of the nonpersistent organic pollutants. Biologic specimens, such as blood, can also indicate long-term internal dose to various metals, including lead and mercury. Environmental measures, on the other hand, provide pathway/source-specific exposure estimates to many of the environmental agents, including those where biologic measurements are not currently feasible (e.g., for particulate matter and for some gaseous criteria pollutants). However, these may be burdensome and costly to either collect or analyze and may not actually indicate the absorbed dose. Thus, an important technical and logistical challenge for the NCS is to develop an appropriate study design with adequate statistical power that will permit detection of exposure-related health effects, based on an optimum set of exposure measurement methods. We anticipate that low-cost, low-burden methods such as questionnaires and screening type assessments of environmental and biologic samples could be employed, when exposures at different critical life stages of vulnerability can be reliably estimated by these simpler methods. However, when reliability and statistical power considerations dictate the need for collecting more specific exposure information, more extensive environmental, biologic, and personal exposure measurements should be obtained from various "validation" subsets of the NCS population that include children who are in different life stages. This strategy of differential exposure measurement design may allow the exposure-response relationships to be tested on the whole cohort by incorporating the information on the relationship between different types of exposure measures (i.e., ranging from simple to more complex) derived from the detailed validation subsamples.

AN - 68443744; 16079075 AB - Health effects associated with particulate matter (PM) show seasonal variations. We hypothesized that these heterogeneous effects may be attributed partly to the differences in the elemental composition of PM. Normal human bronchial epithelial (NHBE) cells and alveolar macrophages (AMs) were exposed to equal mass of coarse [PM with aerodynamic diameter of 2.5-10 microm (PM(2.5-10)], fine (PM(2.5)), and ultrafine (PM(<0.1)) ambient PM from Chapel Hill, North Carolina, during October 2001 (fall) and January (winter), April (spring), and July (summer) 2002. Production of interleukin (IL)-8, IL-6, and reactive oxygen species (ROS) was measured. Coarse PM was more potent in inducing cytokines, but not ROSs, than was fine or ultrafine PM. In AMs, the October coarse PM was the most potent stimulator for IL-6 release, whereas the July PM consistently stimulated the highest ROS production measured by dichlorofluorescein acetate and dihydrorhodamine 123 (DHR). In NHBE cells, the January and the October PM were consistently the strongest stimulators for IL-8 and ROS, respectively. The July PM increased only ROS measured by DHR. PM had minimal effects on chemiluminescence. Principal-component analysis on elemental constituents of PM of all size fractions identified two factors, Cr/Al/Si/Ti/Fe/Cu and Zn/As/V/Ni/Pb/Se, with only the first factor correlating with IL-6/IL-8 release. Among the elements in the first factor, Fe and Si correlated with IL-6 release, whereas Cr correlated with IL-8 release. These positive correlations were confirmed in additional experiments with PM from all 12 months. These results indicate that elemental constituents of PM may in part account for the seasonal variations in PM-induced adverse health effects related to lung inflammation.

AN - 68431728; 16053314 AB - Tryptic digests of human serum albumin and human lung epithelial cell lysates were used as test samples in a novel proteomics study. Peptides were separated and analyzed using 2D-nano-LC/MS/MS with strong cation exchange (SCX) and reversed-phase chromatography and continuous gradient elution. The peptide elution conditions combined simultaneous pH gradient with ammonium acetate salt gradient elution modes. A novel empirical SCX peptide elution score was developed, which accounts for both the number of basic and acidic residues and, in part, their location within a sequence of a peptide. Average scores calculated for the fractionated peptide sequences correlated well with the pH of SCX elution fractions. Multiple peptides with identical amino acid sequences, but differing in cysteine tags possessing different positive charge and different SCX elution properties, were obtained by subjecting the samples to reduction and alkylation with different cysteine alkylating reagents: iodoacetamide, 4-vinylpyridine, and (3-acrylamidopropyl) trimethylammonium chloride. The structurally similar peptides were used as elution standards.

AN - 68053347; 15961341 AB - A quantitative structure-activity relationship (QSAR) model relating electrotopological state (E-state) indices and mutagenic potency was previously described by Cash [Mutat. Res. 491 (2001) 31-37] using a data set of 95 aromatic amines published by Debnath et al. [Environ. Mol. Mutagen. 19 (1992) 37-52]. Mutagenic potency was expressed as the number of Salmonella typhimurium TA98 revertants per nmol (LogR). Earlier work on the development of QSARs for the prediction of genotoxicity indicated that numerous methods could be effectively employed to model the same aromatic amines data set, namely, Debnath et al.; Maran et al. [Quant. Struct.-Act. Relat. 18 (1999) 3-10]; Basak et al. [J. Chem. Inf. Comput. Sci. 41 (2001) 671-678]; Gramatica et al. [SAR QSAR Environ. Res. 14 (2003) 237-250]. However, results obtained from external validations of those models revealed that the effective predictivity of the QSARs was well below the potential indicated by internal validation statistics (Debnath et al., Gramatica et al.). The purpose of the current research is to externally validate the model published by Cash using a data set of 29 aromatic amines reported by Glende et al. [Mutat. Res. 498 (2001) 19-37; Mutat. Res. 515 (2002) 15-38] and to further explore the potential utility of using E-state sums for the prediction of mutagenic potency of aromatic amines.

We utilized radioactive super(7) super(3)As-labeled arsenite and vacuum filtration methodology to determine the binding affinity of arsenite to synthetic peptides. A zinc finger region containing four free sulfhydryls and the hormone binding region containing three free sulfhydryls based on the human estrogen receptor- alpha were studied. Peptide 15 (RYCAVCNDYASGYHYGVWSCEGCKA) bound arsenite with a K sub(d) of 2.2 mu M and B sub(m) sub(a) sub(x) (maximal binding capacity) of 89 nmol/mg protein. Peptide 10 (LECAWQGKCVEGTEHLYSMKCKNV) had a K sub(d) of 1.3 mu M and B sub(m) sub(a) sub(x) of 59 nmol/mg protein. In contrast, the monothiol peptide 19 (LEGAWQGKGVEGTEHLYSMKCKNV) bound arsenite with a higher K sub(d) of 124 mu M and a B sub(m) sub(a) sub(x) of 26 nmol/mg protein. In our studies, amino acids other than cysteine (including methionine and histidine) did not bind arsenite at all. Peptides modeled on the estrogen receptor with two or more nearby free sulfhydryls (two or five intervening amino acids) had low K sub(d) values in the 1-4 mu M range. Peptides containing single sulfhydryls or two sulfhydryls spaced 17 amino acids apart had higher K sub(d) values in the 100-200 mu M range, demonstrating lower affinity. With the exception of peptide 24 which had an unusually high B sub(m) sub(a) sub(x) value of 234 nmol/mg, the binding capacity of the studied peptides was proportional to the number of free cysteines. Binding of trivalent arsenicals to peptides and proteins can contribute to arsenic toxicity and carcinogenicity via altered peptide/protein structure and enzyme function.

Notable in this regard are fungicides, such as prochloraz or fenarimol, which in mammals have the potential to impact endocrine function through inhibition of CYP enzymes involved in steroid metabolism, as well as through antagonism of the androgen receptor(s). The objective of our studies was to assess the effects of prochloraz and fenarimol on reproductive endocrine function in a model small fish species, the fathead minnow (Pimephales promelas), using both in vitro and in vivo assays. The two fungicides inhibited in vitro CYP19 aromatase activity in brain and ovarian homogenates from the fish, with prochloraz exhibiting a greater potency than fenarimol. Prochloraz and fenarimol also bound competitively to the cloned fathead minnow androgen receptor expressed in COS-1 cells. The two fungicides significantly reduced fecundity of the fish in a 21-day reproduction assay at water concentrations of 0.1 (prochloraz) and 1.0 (fenarimol) mg/l. The in vivo effects of prochloraz on plasma steroid (17 beta -estradiol, testosterone, 11-ketotestosterone) and vitellogenin (an estrogen-responsive protein) concentrations, as well as on gonadal histopathology, were consistent with inhibition of steroidogenesis. Fenarimol also affected several aspects of endocrine function in vivo; however, the suite of observed effects did not reflect either aromatase inhibition or androgen receptor antagonism. These studies contribute to a better mechanistic understanding of the extrapolation of effects of endocrine-disrupting chemicals across vertebrate classes.

Examples include pollution source identification; trophic web studies; analysis of water sources for soils, plants; or water bodies, and many others. A common problem is having too many sources to allow a unique solution. We discuss two alternative procedures for addressing this problem. One option is a priori to combine sources with similar signatures so the number of sources is small enough to provide a unique solution. Aggregation should be considered only when isotopic signatures of clustered sources are not significantly different, and sources are related so the combined source group has some functional significance. For example, in a food web analysis, lumping several species within a trophic guild allows more interpretable results than lumping disparate food sources, even if they have similar isotopic signatures. One result of combining mixing model sources is increased uncertainty of the combined end-member isotopic signatures and consequently the source contribution estimates; this effect can be quantified using the IsoError model (http://www.epa.gov/wed/pages/models/isotopes/isoerror1_04.htm). As an alternative to lumping sources before a mixing analysis, the IsoSource mixing model (http://www.epa.gov/wed/pages/models/isosource/isosource.htm) can be used to find all feasible solutions of source contributions consistent with isotopic mass balance. While ranges of feasible contributions for each individual source can often be quite broad, contributions from functionally related groups of sources can be summed a posteriori, producing a range of solutions for the aggregate source that may be considerably narrower. A paleohuman dietary analysis example illustrates this method, which involves a terrestrial meat food source, a combination of three terrestrial plant foods, and a combination of three marine foods. In this case, a posteriori aggregation of sources allowed strong conclusions about temporal shifts in marine versus terrestrial diets that would not have otherwise been discerned.

Microcystins are some of the most commonly detected cyanotoxins. Biological evidence of human exposure may be difficult to obtain due to limitations associated with cost, laboratory capacity, analytic support, and expertise. We investigated the application of an enzyme-linked immunosorbant assay (ELISA) to detect microcystins in human serum. We analyzed ten serum samples collected from dialysis patients who were known to be exposed to a mixture of microcystins during a 1996 outbreak in Brazil. We applied a commercially available ELISA method to detect microcystins in serum, and we compared the ELISA results to a more specific method, liquid chromatography/mass spectrometry (LC/MS) that was also used to detect microcystins in serum. The Spearman correlation coefficient was calculated using serum microcystin concentrations in split samples obtained by the two methods. Serum microcystin concentrations were similar, and we found good correlation of microcystin concentrations between the two methods.

To quantify the coastal ocean nitrogen input to Yaquina Bay, Oregon, nitrate concentrations were measured hourly from a moored sensor during summer upwelling in August 2000 outside the jetties to the estuary. Nitrate concentrations associated with coastal upwelling were generally high (up to 34 mu moll super(-) super(1)). The high-temporal resolution of the nitrate data clearly showed variations with a period of ~12h. The nitrate variations were tightly coupled with temperature variations, with warmer water corresponding to lower nitrate values (5-20 mu moll super(-) super(1)). Discretely-collected samples defined the estuarine conditions during the same period. The estuarine samples also varied from 5 to 20 mu moll super(-) super(1) dissolved nitrate, suggesting that the lower nitrate values were associated with water ebbing from Yaquina estuary. Model calculations, used to estimate the amount of nitrate received by the estuary, indicate that the flux of nitrate into the bay averaged 12,900kgday super(-) super(1) during upwelling. The water chemistry at the nitrate sensor was a complex product of tidal forcing, wind-induced currents and biological utilization of nutrients. A discharge model was used to examine the ebbing tide entrainment hypothesis when ocean currents were steady. Where ocean currents change rapidly in a few hours, the plume trajectories, however, will meander horizontally, fractionate or become patchy. The model analysis supports the tidal Yaquina Bay outflow premise as a cause for nitrate and water property variations near the Yaquina Bay entrance jetties. High-temporal resolution nitrate analyses indicate that near shore coastal waters were influenced by nearby estuarine outflow as well as by coastal upwelling.

For this demonstration, we used the default level interface of the regional mercury cycling model (R-MCM) to simulate epilimnetic total mercury concentrations in Vermont and New Hampshire lakes based on data gathered through the EPAs Regional Environmental Monitoring and Assessment Program (REMAP). The response variable for the GLM was defined as R-MCMs predictive error: the difference between observed mercury concentrations and modeled mercury concentrations in each lake. Least square means of the response variable are used as an estimate of the magnitude and significance of bias, i.e., a statistically discernable trend in predictive errors for a given lake type, e.g., acidic, stratified, or oligotrophic. Using our approach, we determined lake types where significant over-prediction and under-prediction of epilimnetic total mercury concentration was occurring, i.e., regions in parameter space where the model demonstrated significant bias was distinguished from regions where no significant bias existed. This technique is most effective for finding regions of parameter space where bias is significant. Drawing conclusions concerning regions that show no significant bias can be misleading. The significant interaction terms in the GLM demonstrated that addressing this problem using univariate statistical techniques would lead to a loss of important information.

On an annual basis, 2 million individuals require prolonged hospitalization, and an estimated 90 000 patients die due to HAI. Economic damages are reported to exceed $4.5 billion, annually. While many disinfectants, including peracetic acid, have been employed to eradicate infectious bacteria, a lack of understanding their mode of action and the corresponding defense mechanisms hinders successful antimicrobial application. We report here the first transcriptome analysis of the response of Pseudomonas aeruginosa, a pathogen infecting those with cystic fibrosis, upon 20 min exposure to a sublethal concentration (1 mM) of peracetic acid. As a result, we identified that 570 out of a total of 5570 P. aeruginosa genes showed statistically significant transcript level changes. Our findings indicate that (i) many genes associated with cellular protective processes were induced, (ii) the transcription of genes involved in primary metabolic pathways was repressed, and (iii) the transcription of genes encoding membrane proteins and small molecule transporters was altered. We also observed that genes within operons were highly cotranscribed in this study. Finally, this global transcriptional profile can help identify signature genes that are also activated with other oxidative disinfectants, which may be used to design new more effective treatments or more efficaciously apply existing compounds.

Seedling emergence for grasses, forbs and subshrubs was found to mainly occur in a brief pulse at the start of the wet season following fire or the removal of grass biomass. Only a minor number of tree and shrub seedlings were detected overall. Burning, or cutting away the grass layer in unburnt savanna, in both the early (i.e. May) and the late (i.e. October) dry seasons significantly increased seedling emergence over undisturbed savanna that had been unburnt for 3 years. Removing the grass layer in unburnt savanna, during either the early or the late dry season, triggered similar seedling densities to savanna burnt in the early dry season. Late dry season fires promoted the greatest seedling density. We attribute this to the higher intensity, late dry season fires releasing a greater proportion of seed from dormancy, coupled with the higher density of soil seed reserves present in the late dry season.

We estimate a Cobb-Douglas production function to measure the contribution of capital, labor, and materials inputs to output. Our data on pollution abatement expenditures allows us to distinguish between productive and abatement expenditures for each input. We find that abatement expenditures contribute little or nothing to production, although they do not have significant negative effects on the productivity of non-abatement inputs. We also examine within- industry heterogeneity, estimating separate impacts for subgroups of plants, based on their production technology and their types of pollution abatement investment, but find little evidence for significant differences across these groups.

In this study, we hypothesized that PM may activate the angiotensin type 1 receptor (AT sub(1)R), a G protein-coupled receptor that regulates inflammation and vascular function. We investigated the acute effects of St. Louis, Missouri, urban particles (UPs; Standard Reference Material 1648) on the constriction of isolated rat pulmonary artery rings and the activation of extracellular signal-regulated kinases 1 and 2 (ERK1/2) and p38 mitogen-activated protein kinases (MAPKs) in human pulmonary artery endothelial cells with or without losartan, an antagonist of AT sub(1)R. UPs at 1-100 mu g/mL induced acute vasoconstriction in pulmonary artery. UPs also produced a time- and dose-dependent increase in phosphorylation of ERK1/2 and p38 MAPK. Losartan pretreatment inhibited both the vasoconstriction and the activation of ERK1/2 and p38. The water-soluble fraction of UPs was sufficient for inducing ERK1/2 and p38 phosphorylation, which was also losartan inhibitable. Copper and vanadium, two soluble transition metals contained in UPs, induced pulmonary vasoconstriction and phosphorylation of ERK1/2 and p38, but only the phosphorylation of p38 was inhibited by losartan. The UP-induced activation of ERK1/2 and p38 was attenuated by captopril, an angiotensin-converting enzyme inhibitor. These results indicate that activation of the local renin-angiotensin system may play an important role in cardiovascular effects induced by PM.

Valued both commercially and ecologically, oyster populations are threatened by human activity, including dredging, harvesting, and upstream alteration of hydrologic regimes that disrupt the amount, timing and quality of freshwater inflow. Critical life-stage requirements may depend on suitable freshwater inflow, a dynamic variable that reduces salinity, introduces terrestrial materials and mixes water masses with varying physical, chemical and biological properties. Supported by Federal subsidies for agriculture and flood control, freshwater diversions occur along every major stream and river entering the Gulf of Mexico. The Mississippi River has experienced five major upstream modifications. In 1981, Louisiana began to manage upstream freshwater flows to benefit, rather than disrupt, eastern oyster populations. Results from this program are compared with published salinity requirements for different oyster life-stages. Calculation of optimal (monthly) freshwater inflow for oyster seed production indicated that high freshwater inflow is especially critical to early life stages of oysters. We infer that the greatest influence of freshwater inflow is on larval survival, distribution and setting and early survival of spat.

Organic Tracer Compounds from Monoterpenes AN - 17403107; 6525189 AB - In this study, a comparison is made of polar organic compounds found in the field with those produced in secondary organic aerosol from laboratory irradiations of natural hydrocarbons and oxides of nitrogen (NO sub(x)). The field samples comprised atmospheric particulate matter (PM sub(2.5)) collected at Research Triangle Park (RTP), NC, during the summer of 2003, and the laboratory samples originated from the photooxidation of the following monoterpenes: alpha -pinene, beta -pinene, and d-limonene. To determine the structural characteristics of the polar compounds, the filter samples were solvent extracted and derivatized using a technique based on single and multistep derivatizations. The resulting compound derivatives were analyzed by GC-MS in the methane-CI and EI modes. In addition to previously reported biogenic oxidation products (pinic acid, pinonic acid, norpinic acid, nopinone, and pinonaldehyde), seven multifunctional organic compounds were found in both field and laboratory samples. These compounds, which are proposed as possible atmospheric tracers for secondary organic aerosol from monoterpenes, were consistent with the following identifications: 3-isopropyl pentanedioic acid; 3-acetyl pentanedioic acid; 3-carboxy heptanedioic acid; 3-acetyl hexanedioic acid; 2-isopropyl-1,2-dihydroxybutanol; 4-isopropyl-2,4-dihydroxyhexanol; and 3-(2-hydroxy-ethyl)-2,2-dimethyl-cyclobutane carboxylic acid. Initial attempts have been made to quantify the concentrations of these tracer compounds on the basis of surrogate compound calibrations. The occurrence of these compounds in both laboratory and field measurements suggests that secondary organic aerosol originating from biogenic hydrocarbons are contributing to the regional aerosol burden in the southeastern United States. Several of these compounds also appear to contribute to the global aerosol burden in that they have also been identified in Europe and Brazil.

Adult Long-Evans male rats were maintained at 350 g body weight by limited access to a chlorpyrifos-containing diet to produce an intake of 0, 1, or 5 mg/kg/day chlorpyrifos. During the year-long exposure, half of the rats in each dose group received bi-monthly challenges (spikes) of chlorpyrifos, and the other half received vehicle. Rats were periodically tested using a neurological battery of evaluations and motor activity to evaluate the magnitude of the acute response (spike days) as well as recovery and ongoing chronic effects (non-spike days). Effects of the spikes differed as a function of dietary level for several endpoints (e.g., tremor, lacrimation), and in general, the high-dose feed groups showed greater effects of the spike doses. Animals receiving the spikes also showed some neurobehavioral differences among treatment groups (e.g., hypothermia, sensory and neuromotor differences) in the intervening months. During the eleventh month, rats were tested in a Morris water maze. There were some cognitive deficits observed, demonstrated by slightly longer latency during spatial training, and decreased preference for the correct quadrant on probe trials. A consistent finding in the water maze was one of altered swim patterning, or search strategy. The high-dose feed groups showed more tendency to swim in the outer annulus or to swim very close to the walls of the tank (thigmotaxic behavior). Overall, dietary exposure to chlorpyrifos produced long-lasting neurobehavioral changes and also altered the response to acute challenges.

Although the function of these newly generated neurons and the mechanisms that control their birth are unknown, age, activity, diet and psychosocial stress have all been demonstrated to regulate this type of neurogenesis. Little information on the impact of environmental insults on this process has appeared to date. Developmental lead (Pb) exposure has been well documented to impair cognitive function in children and animals and reduce activity-dependent synaptic plasticity in the hippocampus of rodents. Therefore, we examined the effects of this classic environmental neurotoxicant on hippocampal-dependent learning and adult neurogenesis in the hippocampus. Pregnant rats were exposed to a low level of Pb-acetate (0.2%) via the drinking water from late gestation (GD 16) until weaning on postnatal day 21 (PN 21). At weaning, half of the Pb-exposed animals were weaned to control drinking water and the remainder were maintained on Pb water until termination of the study. Animals were paired-housed and on PN 75 were administered a series of injections of a thymidine analog bromodeoxyuridine (BrdU), a marker of DNA synthesis that labels proliferating cells and their progeny. At 12-h intervals for 12 days, rats received an ip injection of BrdU (50 mg/kg). Subjects were sacrificed and perfused 24 h and 28 days after the last injection. Spatial learning was assessed in an independent group of animals beginning on PN 110 using a Morris water maze. No Pb-induced impairments were evident in water maze learning. Immunohistochemistry for the detection of BrdU-labeled cells was performed on 40- mu m coronal sections throughout the hippocampus. Continuous exposure to Pb (Life) reduced the total number of BrdU-positive cells at 28 days without affecting the total number of labeled cells evident 24 h after the last injection. No differences in the number of progenitor cells labeled or surviving were seen between control and treated animals whose Pb exposure was terminated at weaning. Double labeling with BrdU and the glial specific marker, glial acidic fibrillary protein (GFAP) indicated that the bulk of the surviving cells were of a neuronal rather than a glial phenotype. These data reveal that chronic low-level Pb exposure reduces the capacity for neurogenesis in the adult hippocampus. Despite deficits in synaptic plasticity previously reported from our laboratory (e.g., Gilbert, M. E., Mack, C. M., and Lusley, S. M. Brain Res. 1996; 736, 118-124), and now structural plasticity, no significant impact on spatial learning was detected.

Estimates were made using ground-based UV-B data (Brewer spectrophotometers), solar radiation models, GIS tools, field characterization of vegetative features, and quantification of DOC concentration and spectral absorbance. UV-B dose estimates were made for the summer solstice, at a depth of 1 cm in each wetland. The mean dose across all wetlands and parks was 19.3 W-h m super(-2) (range of 3.4-32.1 W-h m super(-2)). The mean dose was lowest in Acadia (13.7 W-h m super(-2)) and highest in Rocky (24.4 W-h m super(-2)). Doses were significantly different among all parks. These wetland doses correspond to UV-B flux of 125.0 mu W cm super(-2) (range 21.4-194.7 mu W cm super(-2)) based on a day length, averaged among all parks, of 15.5 h. Dissolved organic carbon (DOC), a key determinant of water-column UV-B flux, ranged from 0.6 (analytical detection limit) to 36.7 mg C L super(-1) over all wetlands and parks, and reduced potential maximal UV-B doses at 1-cm depth by 1%-87 %. DOC concentration, as well as its effect on dose, was lowest in Sequoia and highest in Acadia (DOC was equivalent in Acadia, Glacier, and Rocky). Landscape reduction of potential maximal UV-B doses ranged from zero to 77% and was lowest in Sequoia.

A bench scale study, performed on a 90-year-old corroded cast-iron pipe section removed from a drinking water distribution system, was used to evaluate the effects of orthophosphate and chloride on iron release, color and turbidity. Experiments showed that an increase in chloride concentration of 100 mg/L significantly increased the concentration of iron released from the pipe section while the presence of orthophosphate at 3 mg/L decreased iron release. Chloride increased and orthophosphate decreased the water color and turbidity caused by the release of iron, but there was not a linear relationship with respect to the concentration of iron released. The control of chloride and orthophosphate concentrations is important in controlling the problem of colored water.

Quantitative assessment of integrated, multimedia models that simulate hundreds of sites, spanning multiple geographical and ecological regions, will ultimately require a comparative approach using several techniques, coupled with sufficient computational power. The Framework for Risk Analysis in Multimedia Environmental Systems-Multimedia, Multipathway, and Multireceptor Risk Assessment (FRAMES-3MRA) is an important software model being developed by the United States Environmental Protection Agency for use in risk assessment of hazardous waste management facilities. The 3MRA modeling system includes a set of 17 science modules that collectively simulate release, fate and transport, exposure, and risk associated with hazardous contaminants disposed of in land-based waste management units (WMU). The 3MRA model encompasses 966 multi-dimensional input variables, over 185 of which are explicitly stochastic. Design of SuperMUSE, a 215 GHz PC-based, Windows-based Supercomputer for Model Uncertainty and Sensitivity Evaluation is described. Developed for 3MRA and extendable to other computer models, an accompanying platform-independent, Java-based parallel processing software toolset is also discussed. For 3MRA, comparison of stand-alone PC versus SuperMUSE simulation executions showed a parallel computing overhead of only 0.57 seconds/simulation, a relative cost increase of 0.7% over average model runtime. Parallel computing software tools represent a critical aspect of exploiting the capabilities of such modeling systems. The Java toolset developed here readily handled machine and job management tasks over the Windows cluster, and is currently capable of completing over 3 million 3MRA model simulations per month on SuperMUSE. Preliminary work is reported for an example uncertainty analysis of Benzene disposal that describes the relative importance of various exposure pathways in driving risk levels for ecological receptors and human health. Incorporating landfills, waste piles, aerated tanks, surface impoundments, and land application units, the site-based data used in the analysis included 201 facilities across the United States representing 419 site- WMU combinations.

While concerns have been raised that such organisms may be capable of inducing transient unintended environmental effects, longer-term perturbations to soil processes and non-target species effects have yet to be demonstrated. In parallel with the growth of the commercial biotechnology industry has come a significant growth in regulatory review processes intended to evaluate the risks of these GMO products. Under the Toxic Substances Control Act (TSCA), certain new microbial products that undergo pre-manufacture review are examined for human and environmental risks using data and other information received in accordance with the U.S. Environmental Protection Agency's (EPA's) "Points to Consider" guidance document. In the risk assessment process, carried out under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Federal Food, Drug and Cosmetic Act (FFDCA) authorities, EPA evaluates both microbial pesticide products and plants with pesticidal properties to determine if Federal safety standards are met. For all pesticide products, including genetically engineered pesticides, EPA receives testing of product composition and chemical properties, human health effects, environmental effects on non-target pests, and the fate of the pesticide in the environment. The EPA's Office of Research and Development supports risk assessment research related to such GMO products. This paper focuses on relevant EPA research and regulatory examples related to soil effects considerations for GMOs.

Improved speciation data for rice can be helpful in estimating inorganic arsenic exposures in the U.S. and in endemic populations. The inorganic arsenic exposure for cooked rice should include both the arsenic in raw rice plus the arsenic absorbed from the water used to prepare it. The amount of arsenic absorbed from water by rice during preparation was assessed using five different types of rice cooked in both contaminated drinking water and arsenic-free reagent water. The rice samples were extracted using trifluoroacetic acid (TFA) and speciated using IC-ICP-MS. The TFA procedure was able to extract 84--104% of the arsenic (As) from the five different cooked rice samples. Chromatographic recoveries ranged from 99% to 116%. The dimethylarsinic acid (DMA) and inorganic arsenic concentration ranged from 22 to 270 ng of As/g of rice and from 31 to 108 ng of As/g of rice, respectively, for samples cooked in reagent water. The overall recoveries, which relate the sum of the chromatographic species back to the total digested concentration, ranged from 89% to 117%. The absorption of arsenic by rice from the total volume of water [1:1 to 4:1 (water:rice)] used in cooking was between 89% and 105% for two different contaminated drinking water samples. A comparison of the TFA extraction to an enzymatic extraction was made using the five rice samples and NIST 1568a rice flour. The two extraction procedures produced good agreement for inorganic arsenic, DMA, and the overall recovery. Through the use of IC--ESI-MS/MS with a parent ion of m/z 153 and fragment ions of m/z 138, 123, and 105, the structure dimethylthioarsinic acid was tentatively identified in two of the rice samples using the enzymatic extraction.

However, the culture tests used to analyze for these bacteria require a long time to complete and do not discriminate between human and animal fecal material sources. One complementary approach is to use chemicals found in human wastewater, which would have the advantages of (1) potentially shorter analysis times than the bacterial culture tests and (2) being selected for human-source specificity. At 10 locations, water samples were collected upstream and at two successive points downstream from a wastewaster treatment plant (WWTP); a treated effluent sample was also collected at each WWTP. This sampling plan was used to determine the persistence of a chemically diverse suite of emerging contaminants in streams. Samples were also collected at two reference locations assumed to have minimal human impacts. Of the 110 chemical analytes investigated in this project, 78 were detected at least once. The number of compounds in a given sample ranged from 3 at a reference location to 50 in a WWTP effluent sample. The total analyte load at each location varied from 0.018 mu g/L at the reference location to 97.7 mu g/L in a separate WWTP effluent sample. Although most of the compound concentrations were in the range of 0.01-1.0 mu g/L, in some samples, individual concentrations were in the range of 5-38 mu g/L. The concentrations of the majority of the chemicals present in the samples generally followed the expected trend: they were either nonexistent or at trace levels in the upstream samples, had their maximum concentrations in the WWTP effluent samples, and then declined in the two downstream samples.

AN - 68545991; 16132454 AB - Ecological risk assessment (ERA) evaluates potential causal relationships between multiple sources and stressors and impacts on valued ecosystem components. ERAs applied at the watershed scale have many similarities to the place-based analyses that are undertaken to develop Total Maximum Daily Loads (TMDLs), in which linkages are established between stressors, sources, and water quality standards, including support of designated uses. TMDLs focus on achieving water quality standards associated with attainment of designated uses. In attempting to attain the water quality standard, many TMDLs focus on the stressor of concern rather than the ecological endpoint or indicators of the designated use that the standard is meant to protect. A watershed ecological risk assessment (WERA), at least in theory, examines effects of most likely stressors, as well as their probable sources in the watershed, to prioritize management options that will most likely result in meeting environmental goals or uses. Useful WERA principles that can be applied to TMDL development include: development and use of comprehensive conceptual models in the Problem Identification step of TMDLs; use of a transparent process for selecting Numeric Targets for TMDLs based on assessment endpoints derived from the management goal or designated use under consideration; analysis of co-occurring stressors likely to cause beneficial use impairment based on the conceptual model; use of explicit uncertainty analyses in the Linkage Analysis step of TMDL development; and frequent stakeholder interactions throughout the process. WERA principles are currently most applicable to those TMDLs in which there is no numeric standard and, therefore, indicators and targets need to be developed, such as many nutrient or sediment TMDLs. WERA methods can also be useful in determining TMDL targets in situations where simply targeting the water quality standard may re-attain the numeric criterion but not the broader designated use. Better incorporation of problem formulation principles from WERA into the TMDL development process would be helpful in improving the scientific rigor of TMDLs.

AN - 68470941; 16092726 AB - Many epidemiology studies have reported associations between inhaled environmental pollutants, especially particles, and mortality or morbidity. Despite these impressive associations, fundamental uncertainties exist as to the underlying pathophysiological mechanisms responsible for mortality or morbidity following exposure to air pollutants. In vitro toxicology provides a powerful approach to describe these mechanisms at the cellular, biochemical, and molecular level. This manuscript will describe some advantages and limitations of in vitro toxicology studies in comparison with epidemiology studies, and human and animal exposure studies. A recent example will also be presented which demonstrates that the response of cultured cells to air pollution particles is similar to the response seen following in vivo exposure to the same particles. This coherence between an in vivo and in vitro response provides relevance to additional in vitro studies that characterize the mechanisms by which these particles cause adverse health effects.

AN - 68428616; 16053064 AB - Background concentrations of tropospheric ozone are increasing and are sensitive to methane emissions, yet methane mitigation is currently considered only for climate change. Methane control is shown here to be viable for ozone management. Identified global abatement measures can reduce approximately 10% of anthropogenic methane emissions at a cost-savings, decreasing surface ozone by 0.4-0.7 ppb. Methane controls produce ozone reductions that are widespread globally and are realized gradually (approximately 12 yr). In contrast, controls on nitrogen oxides (NOx) and nonmethane volatile organic compounds (NMVOCs) target high-ozone episodes in polluted regions and affect ozone rapidly but have a smaller climate benefit. A coarse estimate of the monetized global benefits of ozone reductions for agriculture, forestry, and human health (neglecting ozone mortality) justifies reducing approximately 17% of global anthropogenic methane emissions. If implemented, these controls would decrease ozone by -1 ppb and radiative forcing by approximately 0.12 W m(-2). We also find that climate-motivated methane reductions have air quality-related ancillary benefits comparable to those for CO2. Air quality planning should consider reducing methane emissions alongside NOx and NMVOCs, and because the benefits of methane controls are shared internationally, industrialized nations should consider emphasizing methane in the further development of climate change or ozone policies.

AN - 68091570; 16053114 AB - Sorption of cesium and strontium on kaolinite powders was investigated as a means to minimize the emissions of these metals during certain high-temperature processes currently being developed to isolate and dispose of radiological and mixed wastes. In this work, nonradioactive aqueous cesium acetate or strontium acetate was atomized down the center of a natural gas flame supported on a variable-swirl burner in a refractory-lined laboratory-scale combustion facility. Kaolinite powder was injected at a postflame location in the combustor. Cesium readily vaporized in the high-temperature regions of the combustor, but was reactively scavenged onto dispersed kaolinite. Global sorption mechanisms of cesium vapor on kaolinite were quantified, and are related to those available in the literature for sodium and lead. Both metal adsorption and substrate deactivation steps are important, so there is an optimum temperature, between 1400 and 1500 K, at which maximum sorption occurs. The presence of chlorine inhibits cesium sorption. In contrast to cesium, and in the absence of chlorine, strontium was only partially vaporized and was, therefore, only partially scavengeable. The strontium data did not allow quantification of global kinetic mechanisms of interaction, although equilibrium arguments provided insight into the effects of chlorine on strontium sorption. These results have implications for the use of sorbents to control cesium and strontium emissions during high-temperature waste processing including incineration and vitrification.

AN - 68086027; 16050576 AB - Oxygenated nonpolar organic contaminants (NOCs) are underrepresented in studies of the partitioning and bioavailability of NOCs, including nonylphenol. In this investigation, we evaluated the toxicity, partitioning, and bioavailability of nonylphenol as affected by different forms of organic carbon. Along with organic carbon content, the role of organic carbon polarity was assessed. Toxicity of nonylphenol to a mysid and amphipod was comparable to results reported in the literature for marine organisms with median lethal concentrations (LC50s) of 82.3 and 236 microg/L, respectively. The presence of the different forms of organic carbon in every instance altered, often statistically significantly, the toxicity and bioavailability of the nonylphenol and increased the LC50 by approximately a factor of two. Partition coefficients (KPs) for nonylphenol ranged from 21.3 for cellulose to 9,770 for humic acid; log organic carbon-normalized partition coefficients (KOCs) ranged from 1.71 for cellulose to 4.71 for sediment. An exercise to predict nonylphenol effects using our toxicity data and normalized partition coefficients indicated organic carbon content was most protective and also highlighted the need for further research to better understand nonylphenol bioavailability. These data suggested that with regard to partitioning and bioavailability, the oxygenated NOC nonylphenol behaves like conventional NOCs. The data also suggest that, with refinements, polarity may have some advantages in predicting nonylphenol bioavailability.

AN - 68036519; 15562290 AB - Breast milk consumption is the primary route of infant exposure to certain lipophilic toxicants that have accumulated over decades in maternal adipose tissue, as well as to less persistent toxicants from maternal exposure during lactation. Such infant exposures occur at a time of rapid growth and development when susceptibility to certain toxicants can be greatest. Breast milk and lipid intake rates are presented for the 0-6 and 0-12 month age periods for infants fed according to the American Academy of Pediatrics' current recommendations (exclusive breast-feeding for 0-6 months and continued breast-feeding to 12 months). Intake rates are normalized to infant bodyweight to account for the covariance of consumption and bodyweight. Frequency distributions describe the population variability in intake. For age 0-12 months, daily average milk intake is 100.7 +/- 22.7 g/kg day (mean +/- SD), with a 95th percentile of 153.5 g/kg day. Breast milk intake distributions are also developed for infants exclusively breast-fed (no significant calories from non-breast milk sources) over their first year, and for the entire (nursing and non-nursing) infant population. For short-term exposures, intake can be derived from the regression equation presented here. Lipid intake estimated assuming a 4% lipid content (current risk assessment practice) is compared and found comparable to that derived from measured lipid content. The national trend of increased breast-feeding found in surveys further supports including the breast milk pathway in risk assessment.

AN - 68033620; 15367928 AB - As part of the Children's Total Exposure to Persistent Pesticides and Other Persistent Organic Pollutants (CTEPP) study, we investigated the exposures of preschool children to chlorpyrifos and its degradation product 3,5,6-trichloro-2-pyridinol (TCP) in their everyday environments. During this study, the participants were still able to purchase and apply chlorpyrifos at their homes or day care centers. Participants were recruited randomly from 129 homes and 13 day care centers in six North Carolina counties. Monitoring was performed over a 48-h period at the children's homes and/or day care centers. Samples that were collected included duplicate plate, indoor and outdoor air, urine, indoor floor dust, play area soil, transferable residues (PUF roller), and surface wipes (hand, food preparation, and hard floor). The samples were extracted and analyzed by gas chromatography/mass spectrometry. Chlorpyrifos was detected in 100% of the indoor air and indoor floor dust samples from homes and day care centers. TCP was detected at homes and day care centers in 100% of the indoor floor dust and hard floor surface wipe, in >97% of the solid food, and in >95% of the indoor air samples. Generally, median levels of chlorpyrifos were higher than those of TCP in all media, except for solid food samples. For these samples, the median TCP concentrations were 12 and 29 times higher than the chlorpyrifos concentrations at homes and day care centers, respectively. The median urinary TCP concentration for the preschool children was 5.3 ng/ml and the maximum value was 104 ng/ml. The median potential aggregate absorbed dose (ng/kg/day) of chlorpyrifos for these preschool children was estimated to be 3 ng/kg/day. The primary route of exposure to chlorpyrifos was through dietary intake, followed by inhalation. The median potential aggregate absorbed dose of TCP for these children was estimated to be 38 ng/kg/day, and dietary intake was the primary route of exposure. The median excreted amount of urinary TCP for these children was estimated to be 117 ng/kg/day. A full regression model of the relationships among chlorpyrifos and TCP for the children in the home group explained 23% of the variability of the urinary TCP concentrations by the three routes of exposure (inhalation, ingestion, dermal absorption) to chlorpyrifos and TCP. However, a final reduced model via step-wise regression retained only chlorpyrifos through the inhalation route and explained 22% of the variability of TCP in the children's urine. The estimated potential aggregate absorbed doses of chlorpyrifos through the inhalation route were low (median value, 0.8 ng/kg/day) and could not explain most of the excreted amounts of urinary TCP. This suggested that there were other possible sources and pathways of exposure that contributed to the estimated potential aggregate absorbed doses of these children to chlorpyrifos and TCP. One possible pathway of exposure that was not accounted for fully is through the children's potential contacts with contaminated surfaces at homes and day care centers. In addition, other pesticides such as chlorpyrifos-methyl may have also contributed to the levels of TCP in the urine. Future studies should include additional surface measurements in their estimation of potential absorbed doses of preschool children to environmental pollutants. In conclusion, the results showed that the preschool children were exposed to chlorpyrifos and TCP from several sources, through several pathways and routes. .

AN - 68020074; 15939451 AB - The subject paper describes a procedure for adjusting a risk model based upon a measure of personal exposure (the "UK personal exposure model") in order to attribute an expected rate of gastroenteritis among a group of swimmers to a mean recreational water quality value (enterococci per 100mL). We term the resulting model for group risk the "UK ecologic exposure model." The distinction is essential to establishing recreational water quality guidelines because exposures of individual bathers are not known from a water monitoring program, the only assessment available being some form of ecologic exposure such as a mean log indicator density. While the authors of the subject paper solved the UK ecologic exposure model for only a single point (that value of mean log10 enterococcus density which is expected to result in five extra cases of gastroenteritis per 100 swimmers), we extend their model to show the entire curve over a relevant range of densities. The resulting exposure-response curve is seen to not differ substantially from the existing USEPA model for "highly credible gastrointestinal illness" in marine waters. However, particularly since such correspondence is not guaranteed for future studies or for other existing epidemiological studies, we recommend the direct approach to evaluating ecologic exposure, such as used in the USEPA studies, rather than the indirect approach of the UK ecologic exposure model, given the number of untested assumptions that are necessary for accomplishing the latter.

AN - 68010855; 16003576 AB - To protect public health the German Joint Working Group on Indoor Guidelines of the Federal Environmental Protection Agency and the States' Departments of Health is issuing indoor air guideline values based on a fixed procedure published in 1996. Regarding dearomatized hydrocarbon solvents/white spirits (DAWS--CAS-No. 64742-47-8, 64742-48-9, 64742-88-7, 64741- 65-7) no human data are available. From animal studies, neurotoxicity, developmental toxicity and reproductive toxicity were identified as critical endpoints. For risk evaluation the Hass et al. (2001) study was used as the pivotal study. Based on effects at 4680 mg DAWS/m(3) for the endpoint developmental toxicity, the lowest adverse effect level for chronic exposure is assessed as 400 mg DAWS/m(3). By applying an interspecies factor of 10, an intraspecies factor of 10 and an additional factor 2 referring to the special physiology of children (higher breath rate compared to adults) a so-called health hazard value of 2 mg DAWS/m(3) indoor air and a so-called health prevention value of 0.2 mg DAWS/m(3) are obtained.

AN - 67998197; 15993139 AB - Sources of Enterococcus faecalis isolates from Pensacola Beach, FL. were identified using a library-based approach by applying the statistical method of average similarity to single and composite data sets generated from separate analyses. Data sets included antibiotic resistance analysis (ARA), rep-fingerprints, and fatty acid methyl ester (FAME) profiles. Use of a composite data set composed of ARA and rep-fingerprints, added to the confidence of the identifications. The addition of FAME data to composite data sets did not add to the confidence of identifications. Source identification was performed to better understand risk associated with higher densities of enterococci found in swash zone interstitial water (SZIW) as compared to adjacent bathing water on Pensacola Beach, FL. The "swash zone" is that area of the beach continually washed over by waves. As the potential sources of enterococci were limited in this environment, only two library units, sea gull and human, were constructed. Identification of the beach isolates using a composite data set indicated a sea gull origin. The clonality of the beach isolates suggested that the beach environment selects certain subspecies of E. faecalis.

This study considers both type I error (detecting a bottleneck when there wasn't one) and type II error (failing to detect a bottleneck when there was one) under a variety of scenarios. The two most promising methods were the range in allele size conditioned on the number of alleles, M sub(k), and heterozygosity given the number of alleles, H sub(k), under a two-phase mutation model; in most of the simulations one of these two methods had the lowest type I and type II error relative to other methods. M sub(k) was the method most likely to correctly identify a bottleneck when a bottleneck lasted several generations, the population had made a demographic recovery, and mutation rates were high or pre-bottleneck population sizes were large. On the other hand H sub(k) was most likely to correctly identify a bottleneck when a bottleneck was more recent and less severe and when mutation rates were low or pre-bottleneck population sizes were small. Both methods were prone to type I errors when assumptions of the model were violated, but it may be easier to design a conservative heterozygosity test than a conservative ratio test.

Statistical models such as the fixed-ratio ray design, wherein the mixing ratio (proportions) of the chemicals is fixed across increasing mixture doses, allows for the detection and characterization of interactions among the chemicals. In this study, we tested for interaction(s) in a mixture of five organophosphorus (OP) pesticides (chlorpyrifos, diazinon, dimethoate, acephate, and malathion). The ratio of the five pesticides (full ray) reflected the relative dietary exposure estimates of the general population as projected by the US EPA Dietary Exposure Evaluation Model (DEEM). A second mixture was tested using the same dose levels of all pesticides, but excluding malathion (reduced ray). The experimental approach first required characterization of dose-response curves for the individual OPs to build a dose-additivity model. A series of behavioral measures were evaluated in adult male Long-Evans rats at the time of peak effect following a single oral dose, and then tissues were collected for measurement of cholinesterase (ChE) activity. Neurochemical (blood and brain cholinesterase [ChE] activity) and behavioral (motor activity, gait score, tail-pinch response score) endpoints were evaluated statistically for evidence of additivity. The additivity model constructed from the single chemical data was used to predict the effects of the pesticide mixture along the full ray (10-450 mg/kg) and the reduced ray (1.75-78.8 mg/kg). The experimental mixture data were also modeled and statistically compared to the additivity models. Analysis of the 5-OP mixture (the full ray) revealed significant deviation from additivity for all endpoints except tail-pinch response. Greater-than-additive responses (synergism) were observed at the lower doses of the 5-OP mixture, which contained non-effective dose levels of each of the components. The predicted effective doses (ED20, ED50) were about half that predicted by additivity, and for brain ChE and motor activity, there was a threshold shift in the dose-response curves. For the brain ChE and motor activity, there was no difference between the full (5-OP mixture) and reduced (4-OP mixture) rays, indicating that malathion did not influence the non-additivity. While the reduced ray for blood ChE showed greater deviation from additivity without malathion in the mixture, the non-additivity observed for the gait score was reversed when malathion was removed. Thus, greater-than-additive interactions were detected for both the full and reduced ray mixtures, and the role of malathion in the interactions varied depending on the endpoint. In all cases, the deviations from additivity occurred at the lower end of the dose-response curves.

This method includes a wide range of semivolatile organic contaminants, including pesticides that were deferred during the first UCMR, flame retardants, and pyrethroid pesticides. This paper discusses the rationale for selection and inclusion of the various contaminants included in Method 527 and describes the challenges associated with developing analytical methods that will be used for the occurrence monitoring of such a diverse group of organic molecules. Method 527 employs solid-phase extraction with analysis by gas chromatography/mass spectrometry (GC/MS). The final method preservation scheme requires the storage of samples in amber bottles buffered at pH 3.8 using citric acid to prevent degradation from acid-catalyzed hydrolysis and from UV light. Citric acid is also an effective antimicrobial reagent, preventing this mode of loss during storage. Ethylenediaminetetraacetic acid (EDTA) is added to remove transition metals such as copper, which was determined to degrade target analytes upon storage. Finally, free available chlorine (FAC), which is present in many finished waters and found to degrade a number of the targets, is removed using ascorbic acid. The final method meets all of the EPA UCMR survey requirements for sample storage, precision, accuracy, and sensitivity and will be proposed for use under the UCMR 2.

We used a numerical circulation model coupled to a particle transport model to examine the role that physics play in determining settlement patterns of red drum larvae (Sciaenops ocellatus) in nursery habitat along the Texas coast. We examined supply at various spatial scales (supply to inlet, bays, and individual settlement sites). Temporal patterns in larval settlement in Aransas Bay, Texas, are correlated with several indices of modeled particle supply (number of particles inside the bays, integrated particle input to Lydia Ann Channel, and cumulative number of competent particles in Lydia Ann Channel). High abundances of recently settled red drum in Aransas Bay result from a combination of high larval input, limited habitat for settlement, and proximity of habitat to the inlet. In contrast, larval settlement in Corpus Christi and Redfish Bays does not appear to be related to modeled measures of larval supply.

Semipermeable membrane devices (SPMDs) using dimethylsulfoxide (DMSO) as the fill solvent accumulated each of 17 TICs from the vapor phase. Uptake kinetics experiments for one of these compounds (acrolein) indicated that it was significantly concentrated (i.e. 10% of the 24 h maximum) in as little as 10 min and was concentrated by a factor of over 200 for a 24 h exposure time as measured using both mass and toxicity assays. The effect of each of the TICs on the Microtox bacterial luminescence assay and IQ-Tox Daphnia magna fluorescence assay was determined both from a direct assay and a vapor accumulation assay using SPMDs. Microtox EC sub(50) values (concentrations yielding 50% inhibition) were determined for each of the TICs analyzed. The rank order of the Microtox EC sub(50) values for each of the compounds measured by direct dilution of the TICs into assay buffer was similar but not identical to the Apparent (App) EC sub(50) values determined from the vapor accumulation assay. The ratios of the EC sub(50) to the AppEC sub(50) values were used to calculate apparent toxicity-derived concentration factors (i.e. the toxicity equivalents of compound that concentrate from vapor into the SPMD). EC sub(50) values for the IQ-Tox assay as measured using a 90 min fluorescence assay were, in most cases, similar but not identical to the Microtox EC sub(50) values for individual compounds.

We calculated several commonly used hydrologic indices from discharge and velocity estimates, including daily flow indices, overall flood indices, low flow variables, and ratios or ranges of flow percentiles reflecting the nature of cumulative frequency distributions. Four principal components (PCs) explained 85.9 and 88.6% of the variation of flow metrics among second-and third-order stream sites, respectively. Axes of variation corresponded to a runoff vs. baseflow axis, flow variability, mean flow, and contrasts between flood duration and frequency. Analysis of velocity metrics for third-order streams yielded four PCs corresponding to mean or maximum velocity, Froude number, and inferred shear velocity, as well as spate frequencies vs. intervals associated with different velocity ranges. Using discriminant function analysis, we could discriminate among watershed classes based on region, mature forest, or watershed storage as a function of flow metrics. For second-order streams, median flow (Qs sub(50)) increased as watershed storage increased. North Shore streams showed a more skewed distribution and greater spread of discharge values than did South Shore streams for both stream orders, while third-order North Shore streams exhibited a higher frequency of spates. Independent of regional differences, loss of mature forest increased the range of variation between baseflow and peak flows, and depressed baseflow. Consistent with our initial model for watershed classification, Classification and Regression Tree (CART) analysis confirmed significant thresholds of change in flow metrics averaging between 0.506 and 0.636 for fraction mature forest and between 0.180 and 0.258 for fraction watershed storage.

These actions include the Acid Rain NO sub(x) regulations, the Ozone Transport Commission's NO sub(x) Budget Program, and the NO sub(x) SIP Call rulemakings. In addition to these regulations, the recent Interstate Air Quality Rulemaking proposal and other bills in the Congress are focusing on additional reductions of NO sub(x). Industrial combustion sources accounted for about 18% of NO sub(x) emissions in the United States in 2000 and constituted the second largest emitting source category within stationary sources, only behind electric utility sources. Based on these data, reduction of NO sub(x) emissions from industrial combustion sources is an important consideration in efforts undertaken to address the environmental concerns associated with NO sub(x). This paper discusses primary and secondary NO sub(x) control technologies applicable to various major categories of industrial sources. The sources considered in this paper include large boilers, furnaces and fired heaters, combustion turbines, large IC engines, and cement kilns. For each source category considered in this paper, primary NO sub(x) controls are discussed first, followed by a discussion of secondary NO sub(x) controls.

There are two broad approaches under development to controlling mercury emissions from coal-fired electric utility boilers: (1) powdered activated carbon (PAC) injection; and (2) multipollutant control, in which Hg capture is enhanced in existing and new sulfur dioxide (SO sub(2)), nitrogen oxides (NO sub(x)), and particulate matter (PM) control devices. To help inform the recent EPA rulemaking proposal, estimates of performance levels and related costs associated with the above mercury control approaches were developed. This work presents these estimates. Estimates of cost for PAC injection range from 0.003 to 3-096 mills/kWh. In general, the higher costs are associated with the plants using spray dryers and electrostatic precipitators (ESPs) or plants using hot-side ESPs, which represent a minority of power plants. Excluding these plants, cost estimates range between 0.003 and 1.903 mills/kWh. At the low end of the cost ranges, 0.003 mills/kWh, it is assumed that no additional control technologies are needed, but mercury monitoring will be necessary. In these cases, high mercury removal may be the result of the type of NO sub(x) and SO sub(2) control measures currently used, such as combinations of selective catalytic reduction and wet flue gas desulfurization or spray drier absorbers with fabric filters on bituminous coal-fired boilers. Because mercury control approaches are under development at present, cost and performance estimates are preliminary and are expected to be refined as mercury control technologies are matured to commercial status. Factors that may affect the performance of these technologies include speciation of mercury in flue gas, the characteristics of the sorbent, and the type(s) of PM, NO sub(x), and SO sub(2) controls used. The effect of these factors may not be entirely accounted for in the data points that form the basis for this work. Ongoing research is expected to address these issues.

The experiments took place in a facility with two raceways of similar size and water flow rate and with similar stocks of rainbow trout Oncorhynchus mykiss. Fish in one raceway were fed Select P, while those in the other raceway received the same diet with the addition of guar gum. When the fish were given feed containing the dietary binder, feces were discharged in visibly and significantly larger particles. Furthermore, in effluent from the raceway in which fish were fed the diet plus binder, the particle-bound fractions of phosphorus and Kjeldahl nitrogen were increased at the expense of the respective dissolved fraction by about 18% and 8%, respectively, possibly reflecting a reduced leaching of nutrients from the larger particles. Drum filter removal efficiency was significantly higher for the effluents from the fish fed the binder-containing diet; for both total suspended solids and total phosphorus there was an improvement of about 40%. For total Kjeldahl nitrogen the improvement was about 17%. For the particulate fraction, removal values were even higher, efficiency improving about 47% for particulate phosphorus and 34% for particulate Kjeldahl nitrogen.

This paper argues that integration of a risk assessment approach into the EIA is a logical extension of the EIA process and provides a more robust method for assessing comparative risks of proposed alternatives, and integrating ecological risks with economic and social cost-benefit analyses. Risk assessment is the process of estimating the likelihood and magnitude of the occurrence of an unwanted, adverse effect. It begins with a well-defined problem formulation step that ensures involvement of stakeholders, uses available or newly developed scientific information to ascribe probabilities to the likelihood of fire initiation under various forest management practices, and describes or quantifies the magnitude of effects associated with fires of various frequencies and intensities. The risk characterization step provides comprehensive statements of risk, including assertions about uncertainty, and communicates results in a clear and intelligible manner to resource managers and interested stakeholders. Risk assessment uses probabilistic modeling to incorporate environmental stochasticity and experimental uncertainty, and incorporates spatial attributes, simultaneous multiple risks, comparative analyses of different risks, socioeconomic concerns, and ecological effects into the analysis. Placed within the EIA process, risk assessment provides a robust framework for reaching agreement on risks of uncharacteristic wildfires under a variety of proposed management scenarios.

These losses increase when N sources such as fertilizer are applied to grazing land. The objectives of this work were to (1) study the impact of dairy effluent (DE) or urea on N losses and plant uptake when DE or urea was applied with and without cattle urine and; (2) determine the effect of organic C rich DE on the fate of urine N. The experiment was conducted using lysimeters that contained Templeton sandy loam soil extracted from a pasture in New Zealand. Application of DE resulted in significantly less (p < 0.05) NO sub(3) super(-) leaching compared with urea in the first year, but not in the second year. Differences between years could be attributed to the comparatively lower C:N ratio of applied DE in the second year, causing relatively greater N mineralization and greater NO sub(3) super(-) leaching. Differences could also be due to cumulative effects of DE (first year applied) on second year NO sub(3) super(-) leaching. Total annual pasture N uptake was similar for DE and urea treatments. During the first year, the average NO sub(3) super(-) concentration was lower when DE was combined with urine compared to urine alone, but not in the second year. The combination of DE with urine resulted in significantly greater (p < 0.01) annual pasture N uptake compared with the urine alone treatment in both years. Urine plus urea resulted in the greatest leaching losses in both years, but its impact on pasture N uptake was mixed. The total leaching loss of N from urine plus DE (90 kg N ha super(-1)) was similar to urine alone (77 kg N ha super(-1)) in the second year. Likewise, the annual percentage of super(15)N recovered in the leachate from urine plus DE (9%) was not significantly different from urine alone (6%). However, super(15)N recoveries revealed that the contribution of urine N to NO sub(3) super(-) leaching was greater when urine was combined with DE (98.8%) compared to urine alone (83%). The greater NO sub(3) super(-) leaching from urine when combined with DE could be a result of greater nitrification due to the low C:N ratio of DE. Additionally, the annual percentage of urine N uptake by the pasture from urine plus DE (29%) was significantly less than from urine alone (39%) (p < 0.01). The application of organic C rich DE had no significant effect on soil N retention or denitrification when combined with urine.

AN - 68053144; 16022700 AB - A method for estimating long-term exposures from short-term measurements is validated using data from a recent EPA study of exposure to fine particles. The method was developed a decade ago but long-term exposure data to validate it did not exist until recently. In this article, exposure data from repeated visits to 37 persons over 1 year (up to 28 measurements per person) are used to test the model. Both fine particle mass and elemental concentrations measured indoors, outdoors, and on the person are examined. To provide the most stringent test of the method, only two single-day distributions are randomly selected for each element to predict the long-term distributions. The precision of the method in estimating the long-term geometric mean and geometric standard deviation appears to be of the order of 10%, with no apparent bias. The precision in estimating the 99 th percentile ranges from 19% to 48%, again without obvious bias. The precision can be improved by selecting a number of pairs of single-day distributions instead of just one pair. Occasionally, the method fails to provide an estimate for the long-term distribution. In that case, a repeat of the random selection procedure can provide an estimate. Although the method assumes a log-normal distribution, most of the distributions tested failed the chi-square test for log-normality. Therefore, the method appears suitable for application to distributions that depart from log-normality.

AN - 68040890; 16020190 AB - Mycobacterium avium complex (MAC) is a group of ubiquitous and opportunistic bacterial pathogens included on the U.S. Environmental Protection Agency Drinking Water Contaminant Candidate List. The risk of contracting a disseminated MAC infection is primarily limited to the immunocompromised, including those with advanced acquired immunodeficiency syndrome (AIDS). These infections likely result from exposures to MAC-contaminated tap water, food, or soil, although the epidemiologic evidence is insufficient to implicate a specific medium. The objective of this study was to assess tap water exposure to MAC in the U.S. population with advanced AIDS, defined here as having fewer than 100 CD4(+) cells/mm(3) of blood. Using limited data on the detection of MAC and self-reported post-tap treatment practices, two exposure models were developed to simulate the likelihood of exposure to MAC via tap water consumption in this sensitive population. The first model integrated data from studies that described sources of water for consumption and post-tap treatment rates in cohorts infected with human immunodeficiency virus (HIV(+)). The second model used data from a study that categorized the fraction of water intake consisting of tap water that was not further treated. Approximately 1500 individuals with advanced AIDS were estimated to ingest tap water with detectable concentrations of MAC organisms daily. Additional studies on tap-water use in U.S. HIV(+) populations are needed to confirm these findings. Longitudinal and cross-sectional studies on the occurrence of MAC in tap water, particularly in regions with large HIV(+)/AIDS populations, would help address some of the uncertainty in these exposure estimates.

AN - 68037437; 16020183 AB - Computational modeling has an increasing role in analyses of biological effects, including how the body handles chemicals (i.e., pharmacokinetics or toxicokinetics) and how the body responds to chemicals (i.e., pharmacodynamics or toxicodynamics). Pharmacokinetic models increasingly describe not just adult humans and animals, but also changes with age and life stage (e.g., pregnancy and fetal exposures, lactational exposures, and childhood growth). Physiologically based pharmacokinetic models provide an important route to estimate the potential changes in internal dose that may occur throughout the life cycle. These models require inputs describing changes in physiology, metabolism, and exposure with age and life stage. A particular challenge exists when the "equivalent" developmental period in the rodents and humans differs (e.g., early postnatal in rats and in utero in humans) such that the "equivalent" window of susceptibility to toxic effects of the chemical may involve substantially different exposures (e.g., lactational versus placental transfer). Pharmacodynamic modeling could similarly address changes with age, but few such models currently exist. The growth of systems biology is anticipated to change this over the coming decade.

AN - 68036861; 16020189 AB - Since the 2001 attacks in which Bacillus anthracisspores were mailed to various media offices and two U.S. Senators, considerable interest has focused on developing estimates of the risk of contracting inhalational anthrax from exposure to such spores. Credible risk estimates would have significant utility in establishing future cleanup goals for contaminated sites. To perform a meaningful risk assessment, one needs sufficient data to identify the hazards, conduct dose-response assessment, and assess exposure. This report reviews the existing data on mortality produced by Bacillus anthracisspores in laboratory animals and humans. In particular, it focuses on the 11 cases of inhalational anthrax resulting from the 2001 attacks and their impact on hazard identification activities. It also addresses factors that may contribute to increased risk among exposed populations and the sources of uncertainty in dose response analysis. The article examines the state of the science for assessing exposure levels to Bacillus anthracis spores and concludes that significant challenges exist to performing robust assessments of risk. This conclusion supports the policy position of the U.S. Environmental Protection Agency (EPA) that there should be no growth of Bacillus anthracis spores from all postremediation environmental samples, for the cleanup of a site to be judged effective and for that site to be considered safe for reoccupancy. This has been the ultimate criterion for efficacy of cleanups performed in response to the 2001 anthrax attacks. JF - Journal of toxicology and environmental health.

AN - 68036331; 16020035 AB - Ultrafine particulate matter (PM) in the air may be harmful to health, particularly in elderly subjects. From the dosimetry point of view, it is not known if the elderly subjects are more susceptible to exposure to ultrafine PM. We measured the total deposition fraction (TDF) of ultrafine PM (NMD = 0.04-0.1 microm in number median diameter) in the lungs of healthy, elderly subjects (age = 69 +/- 5 yr) and compared the results with those obtained from young adults (age = 31 +/- 4 yr) in an earlier study. Subjects inhaled the aerosols with six different breathing patterns: three different tidal volumes (V(t) = 500, 750, and 1000 ml) and two flow rates (Q) for each V(t). TDF was measured breath by breath in situ by measuring aerosol concentrations on inhalation and exhalation using an ultrafine condensation particle counter. Mean TDF (+/-SD) of the elderly subjects was 0.43 +/- 0.03, 0.36 +/- 0.04, 0.31 +/- 0.03, and 0.27 +/- 0.02 for NMD = 0.04, 0.06, 0.08, and 0.1 microm, respectively, for V(t) = 500 ml and Q = 250 ml/s. These and all other results were very similar to those of young adults. The results suggest that healthy, elderly subjects are not subjected to a greater respiratory dose of ultrafine PM than young adults under the same exposure conditions.

AN - 68036299; 16020184 AB - A number of organizations have developed acute inhalation health reference values, each with (1) a specific purpose, (2) populations to protect, (3) exposure scenarios (accidental releases, workplace, routine excursions of ambient levels), and (4) severity of adverse health effects considered in their development. The first section of this article reviews the existing values from different organizations and describes their purposes and method of development. The second part of the article provides a comparative review of how the values were derived, the critical endpoints considered for each value, the populations being protected by each value, and the potential for use outside of their intended purpose (e.g., Homeland Security, regulatory analysis, etc.). Additionally, an analysis of the acute inhalation reference values that was developed in support of the Office of Air and Radiation's residual risk assessment for hazardous air pollutants is presented and reviewed. The third and final part of the article focuses on the efforts of the U.S. Environmental Protection Agency (EPA) to develop a set of less-than-lifetime reference values, along with a discussion of how that effort fits with the existing sets of values described in the prior sections.

AN - 68036263; 16020180 AB - Benefit-cost analysis is of growing importance in developing policies to reduce exposures to environmental contaminants. To quantify health benefits of reduced exposures, economists generally rely on dose-response relationships estimated by risk assessors. Further, to be useful for benefits analysis, the endpoints that are quantified must be expressed as changes in incidence of illnesses or symptoms that are readily understood by and perceptible to the layperson. For most noncancer health effects and for nonlinear carcinogens, risk assessments generally do not provide the dose-response functions necessary for economic benefits analysis. This article presents the framework for a case study that addresses these issues through a combination of toxicology, epidemiology, statistics, and economics. The case study assesses a chemical that disrupts proper functioning of the thyroid gland, and considers the benefits of reducing exposures in terms of both noncancer health effects (hypothyroidism) and thyroid cancers. The effects are presumed to be due to a mode of action involving interference with thyroid-pituitary functioning that would lead to nonlinear dose response. The framework integrates data from animal testing, statistical modeling, human data from the medical and epidemiological literature, and economic methodologies and valuation studies. This interdisciplinary collaboration differs from the more typical approach in which risk assessments and economic analyses are prepared independently of one another. This framework illustrates particular approaches that may be useful for expanded quantification of adverse health effects, and demonstrates the potential of such interdisciplinary approaches. Detailed implementation of the case study framework will be presented in future publications. JF - Journal of toxicology and environmental health.

AN - 68034848; 16020185 AB - The potential human health risk(s) from chemical exposure must frequently be assessed under conditions for which adequate human or animal data are not available. The default method for exposure-duration adjustment, based on Haber's rule, C (external exposure concentration) or C(n) (the ten Berge modification) x t (exposure duration) = K (a constant toxic effect), has been criticized for prediction errors. A promising alternative approach to duration adjustment is based on equivalence of internal dose, that is, target-tissue dose levels, across different exposure durations. A proposed methodology for dose-duration adjustments for acute exposure guideline levels (AEGLs) based on physiologically based pharmacokinetic (PBPK) estimates of dose is illustrated with trichloroethylene (TCE). Steps in this methodology include: (1) selection and evaluation, or development and evaluation, of an appropriate PBPK model; (2) determination of an appropriate measure of internal dose; (3) estimation with the PBPK model of the tissue dose (the target tissue dose) resulting from the external exposure conditions (concentration, duration) of the critical effect; (4) estimation of the external exposure concentrations required to achieve tissue doses equivalent to the target tissue dose at exposure durations of interest; and (5) evaluation of sources of variability and uncertainty. For TCE, this PBPK modeling approach has allowed determination of dose metrics predictive of the acute neurotoxic effects of TCE and dose-duration adjustments based on estimates of internal dose.

AN - 68034339; 16020034 AB - Much of the information on the toxicity of particulate matter (PM) comes from studies in which laboratory rats were exposed to PM by inhalation or instillation. Optimal use of these toxicologic data requires extrapolation to the human scenario. Assuming that comparable doses should cause comparable effects across species and that species respond similarly to a given dose at a target site, extrapolations only require that dose be defined and then characterized. Dose may be defined in terms of a PM indicator (e.g., particle number or mass), a respiratory region, and the time over which the dose is integrated (i.e., deposited versus retained dose and incremental versus accumulated dose). Dose must also be normalized: for example, unit of dose per body mass, respiratory region surface area, or number of alveolar macrophages. The parameters chosen to define a normalized dose can drastically affect the rat exposure concentration required to provide a normalized dose equivalent to that occurring in a human. The publicly available multiple path particle dosimetry model developed by CIIT Centers for Health Research was used to predict particle deposition and retention in rats and humans. Estimates of particle concentration and exposure duration required for a rat to receive the same dose as received by a human were obtained with consideration of daily activity levels and ambient PM size distributions. These techniques were also used to compare dose and response between rats and humans in several published studies. Results indicate that the relationship between PM dose and response may differ between rats and humans. For acute PM exposures, rats may be less susceptible to inflammatory responses than humans. For chronic exposures to high levels of PM, however, an overload of alveolar clearance in rats may cause them to become more susceptible than humans to adverse pulmonary effects. The dosimetric calculations indicate that to achieve nominally similar acute doses per surface area in rats, relative to humans undergoing moderate to high exertion, PM exposure concentrations for rats would need to be somewhat higher than for humans. Since the clearance of PM is faster from the lung of rats than humans, much higher exposure concentrations are required for the rat to simulate retained burdens. In other cases, rats will require lower exposures than humans to have comparable doses, illustrating the complexity of such analyses. To make accurate estimates of dose, it is essential to have accurate and complete information regarding exposure conditions-that is, not only concentration and duration of exposure, but also the aerosol size distribution. Establishing a firm linkage between exposure and dose requires that consideration be given to particle characteristics, definitions of dose metrics, and biological normalizing factors.

AN - 68033503; 16020031 AB - Direct calculation of delivered dose in the species of interest potentially affects the magnitude of an uncertainty factor needed to address extrapolation of laboratory animal data to equivalent human exposure scenarios, thereby improving the accuracy of human health risk estimates. Development of an inhalation reference concentration (RfC) typically involves extrapolation of an effect level observed in a laboratory animal exposure study to a level of exposure in humans that is not expected to result in an appreciable health risk. The default dose metric used for respiratory effects is the average deposited dose normalized by regional surface area. However, the most relevant dose metric is generally one that is most closely associated with the mode of action leading to the response. Critical factors in determining the best dose metric to characterize the dose-response relationship include the following: the nature of the biological response being examined; the magnitude, duration, and frequency of the intended exposure scenario; and the mechanisms by which the toxicants exert their effects. Dosimetry models provide mechanistic descriptions of these critical factors and can compute species-specific dose metrics. In this article, various dose metrics are postulated based on potential modes of action for poorly soluble particles (PSP). Dosimetry models are used to extrapolate the internal dose metric across species and to estimate the human equivalent concentration (HEC). Dosimetry models for the lower respiratory tract (LRT) of humans and rats are used to calculate deposition and retention using the principle of particle mass balance in the lower respiratory tract. Realistic asymmetric lung geometries using detailed morphometric measurements of the tracheobronchial (TB) airways in rats and humans are employed in model calculations. Various dose metrics are considered for the TB and pulmonary (P) regions. Because time is an explicit parameter incorporated in species-specific constants such as mucociliary clearance rates used in the models, the impact of the application of optimal model structures to refine adjustments and assumptions used in default risk assessment approaches to address exposure duration are discussed. HEC estimates were found for particles ranging in sizes that corresponded to existing toxicity studies of PSP (0.3 to 5 microm). A dose metric expressed as number of particles per biologically motivated normalization factors (e.g., number of ventilatory units, number of alveoli, and number of macrophages) was lower than the current default of mass normalized to regional surface area for either deposited or retained dose estimates. Retained dose estimates were lower than deposited dose estimates across all particle sizes evaluated. Dose metrics based on the deposited mass per unit area in small and large airways of the TB region indicate HECs of 1 to 5 times those of rats: that is, an equivalent exposure to humans which would achieve the same internal dose as in the rat would be 1 to 5 times greater. HEC estimates in the TB region increase with an increase in particle size for particles from 0.3 to 2 microm in the small airways and >3 microm in the large airways. The HEC decreases with increase in particle size in the P region across all particle sizes studied, and the decrease has a more significant slope for those particles >2 microm due to the limited inhalability of particles this size in rats relative to humans. Our modeling results elucidate a number of important issues to be considered in assessing current default approaches to dosimetry adjustment for inhaled PSP. Simulation of realistic, polydisperse particle distributions for the human exposure scenario results in reduced HEC estimates compared to estimates derived with the experimental particle distribution used in the laboratory animal study. Consideration should be given also to replacing the default dose metric of normalized deposited dose in the P region with normalized retained dose. Chronic effects are more likely due to retained dose and estimates calculated using retained versus deposited mass are shown to be lower across all particle sizes. Because dose metrics based on normalized particle number rather than normalized mass result in lower HEC estimates, use of inhaled mass as the default should also be revisited, if the pathogenesis suggests particle number determines the mode of action. Based on demonstrated age differences, future work should pursue the construction of "lifetime" estimates calculated by sequentially appending simulations for each specific age span.

AN - 67992678; 15990707 AB - A hyperdynamic circulatory pattern in advanced liver disease is known since a long time. The first studies evaluating cardiac function in cirrhosis were performed in patients with alcoholic liver disease and thus this condition was attributed to the toxic effects of ethanol. A reduced performance of the left ventricle after physical and pharmacological strains along with an altered diastolic function has been demonstrated also in postviral cirrhosis. Many factors are involved in advanced cirrhosis whereas little is known in the earlier stages of disease. To this aim we have investigated patients with different stages of hepatitis C virus (HCV)-related liver disease to detect the time-course of diastolic dysfunction. An impaired relaxation and increased thickness of left ventricular walls along with an altered pattern of transmitral flow can be easily detected by means of echocardiography. In chronic hepatitis diastolic function is preserved but increased thickness of left ventricle parietal walls can be detected in patients with fibrosis on liver biopsy. The typical pattern of diastolic dysfunction is observed in Child A cirrhotic patients and in Child C ascitic patients but thickness of parietal walls is more relevant in the former group. Chronic aldosterone blockade could exert favourable effects in heart remodeling suggesting a potential role of these drugs in cirrhotic cardiomyopathy. The presence of increased thickness of left ventricle parietal walls in chronic hepatitis C in the precirrhotic stage point to a putative role of HCV in this heart structural abnormality that can become a co-factor in the more advanced stages of cirrhosis when portal hypertension and its deleterious effects on systemic hemodynamics, cardiac function and structure become manifest.

AN - 67982593; 15984796 AB - Numerous studies have demonstrated the efficiency of ultraviolet (UV) radiation for the inactivation of oocysts of Cryptosporidium parvum. In these studies inactivation is measured as reduction in oocysts. A primary goal is to estimate the UV radiation required to achieve a high degree of inactivation. Different lots of Cryptosporidium parvum oocysts are used in these studies, and the inactivation rate may vary depending on the lot of oocysts used. The goal of this paper is to account for the error in estimating the amount of inactivation after exposure to UV radiation, and for the effect of lot variability in determining the required UV radiation. A Bayesian approach is used to simultaneously model the logistic dose-response model and the UV inactivation kinetic model. The oocysts lot variability is incorporated using a hierarchical Bayesian model. Posterior distributions using Markov Chain Monte Carlo method is used to obtain estimates and Bayesian credible interval for the required UV radiation to achieve a given inactivation level of Cryptosporidium parvum oocysts.

AN - 67820698; 15891452 AB - The opportunity to write a historical review of the field of radiation biology allows for the viewing of the development and maturity of a field of study, thereby being able to provide the appropriate context for the earlier years of research and its findings. The pioneering work of Muller, Sax, and McClintock, and many others, has stood the test of time. The idea that x-rays could damage the genetic material and result in interactions that could lead to gene mutations and a range of chromosomal alterations is now interpretable in terms of induced DNA damage and errors of DNA repair. The expanded idea that such genetic alterations can be induced by DNA damage that is produced by one or two tracks of ionizing radiation remains the mainstay of radiation biology. The impact of the more recent molecular approaches to unraveling the mechanism behind this simple concept has confirmed this fundamental observation. The remarkable advances have allowed for a fairly complete understanding of the specific types of DNA damage induced by ionizing radiations and the pivotal role played by the errors of repair of double-strand breaks. Given our considerably enhanced knowledge of the details of the DNA repair processes involved, misrepair is a very unlikely event. The role of potential confounders of the concept of dose-response (e.g., bystander effects, genomic instability, and adaptive responses) is taking on a growing importance to the field. The evolving need is to begin to consider mechanistically-based dose-response models for cancer risk such that any potential impact of confounders on the response at low, environmental doses can be assessed. Thus, radiation biology research has always had a focus on how best to protect human health from radiation exposures and will continue to do so.

Oil field discharges of produced water create wetlands that provide habitat for aquatic migratory birds and other wildlife. Wetlands surveyed in Wyoming from 1996 to 1999 showed that inefficient oil-water separation contributed to the discharge of oil into some wetlands receiving produced water. Over 62% of the sites surveyed had inadequate measures to exclude wildlife, particularly migratory birds, from entering skim pits used to separate oil from produced water. The risk of oil discharges into wetlands can be reduced significantly by proper maintenance of equipment used to separate oil from produced water; immediate removal of oil from production skim pits or tanks to prevent overflow into the receiving wetlands; installation of secondary or tertiary containment ponds or tanks to capture any oil accidentally discharged from the primary or secondary pits or tanks; or construction of wetland-based treatment systems for removing metals, radionuclides, and hydrocarbons from the produced water prior to discharge into natural wetlands. Wildlife mortality in skim pits can be prevented using closed containment systems, eliminating pits or keeping oil off open pits or ponds, or using effective and proven wildlife exclusionary devices.

The site is a shallow glacial outwash aquifer located near Bemidji in northern Minnesota that became contaminated when oil spilled from a broken pipeline in August 1979. In the study area, separate-phase oil forms a subsurface oil body extending from land surface to about 1 m (3.3 ft) below the 6-8-m (20-26 ft)-deep water table. Oil saturation in the sediments ranges from 10-20% in the vadose zone to 30-70% near the water table. At depths below 2 m (6.6 ft), degradation of the separate-phase crude oil occurs under methanogenic conditions. The sequence of methanogenic alkane degradation depletes the longer chain n-alkanes before the shorter chain n-alkanes, which is opposite to the better known aerobic sequence. The rates of degradation vary significantly with location in the subsurface. Oil-coated soils within 1.5 m (5 ft) of land surface have experienced little degradation where soil water saturation is less than 20%. Oil located 2-8 m (6.6-26 ft) below land surface in areas of higher recharge has been substantially degraded. The best explanation for the association between recharge and enhanced degradation seems to be increased downward transport of microbial growth nutrients to the oil body. This is supported by observations of greater microbial numbers at higher elevations in the oil body and significant decreases with depth in nutrient concentrations, especially phosphorus. Our results suggest that environmental effects may cause widely diverging degradation rates in the same spill, calling into question dating methods based on degradation state.

Of these, 12,863 were identified as exploration- and production-related releases of oil or saltwater from identified geographic areas. The primary reported origins of oil and saltwater releases were leaks from lines, tanks, wellheads, surface equipment, and pits. Important reported causes of fluid releases range from common overflows (tank, pit, and dike), intentional dumping or other illegal activity, storms, fires or explosions, accidents (including the actions of livestock), and to occasional corrosion. Approximately 34% of all recent oil or saltwater releases resulted in reported injury to environmental receptors (surface water, crops or livestock, soil, fish, or wildlife). For the 10-yr period of record, 41% of all exploration and production complaints to OCC involved the release of oil or saltwater. On an annual basis, complaints involving the release of fluids decreased from 65.8% in 1993 to 46.1% in 2002. Releases specifically identified as involving oil or saltwater comprised 76.1% of all fluid releases. Quantified releases of oil had a median volume of 10 bbl, whereas quantified releases of saltwater had a median volume of 40 bbl. For those releases in which the volume of both oil and saltwater were quantified, the volume of saltwater spilled was approximately 76% of the total volume.

At this site, topsoil was underlain by clay-rich subsoil, which had resulted in leaching and transport of brine components from the site to an environmental receptor (farm pond) downgradient. Encouraging further movement of brine components using natural drainage patterns would have only further contaminated the pond. A subsurface drainage system was installed to intercept brine components, enhance the lateral subsurface transport process, and prevent further contamination of the pond. Chloride and sodium concentrations in the soil were reduced by an average of 93 and 78%, respectively, in the 4 yrs after the subsurface drainage system was installed. More importantly, approximately 95% of the site revegetated during this period. This is in stark contrast to the complete lack of vegetation before the current work was initiated. A thick layer of prairie hay was applied across the surface of this site after the subsurface drainage system was installed. In addition to limiting the rate of evaporation from the site, this organic material appears to have also been a significant factor in desalination and revegetation of the site. The fibrous hay enhanced leaching after mechanical disruption of the soil and provided soil organic matter that helped to build soil structure and sustain the soil ecosystem. Based on the results from this study, a two-step remediation strategy for brine-impacted topsoil is proposed. The first step involves the tilling of hay and fertilizer into the soil, whereas the second step involves a subsurface drainage system, if necessary.

S. Geological Survey Osage-Skiatook Petroleum Environmental Research Site A, Osage County, Oklahoma AN - 51709418; 2005-043163 AB - The U.S. Geological Survey is investigating the impacts of oil and gas production on soils, groundwater, surface water, and ecosystems in the United States. Two sites in northeastern Oklahoma (sites A and B) are presently being investigated under the Osage-Skiatook Petroleum Environmental Research Project. Oil wells on the lease surrounding site A in Osage County, Oklahoma, produced about 100,000 bbl of oil between 1913 and 1981. Prominent production features on the 1.5-ha (3.7-ac) site A include a tank battery, an oil-filled trench, pipelines, storage pits for both produced water and oil, and an old power unit. Site activities and historic releases have left open areas in the local oak forest adjacent to these features and a deeply eroded salt scar downslope from the pits that extends to nearby Skiatook Lake. The site is underlain by surficial sediments comprised of very fine-grained eolian sand and colluvium as much as 1.4 m (4.6 ft) thick, which, in turn, overlie flat-lying, fractured bedrock comprised of sandstone, clayey sandstone, mudstone, and shale. A geophysical survey of ground conductance and concentration measurements of aqueous extracts (1:1 by weight) of core samples taken in the salt scar and adjacent areas indicate that unusual concentrations of NaCl-rich salt are present at depths to at least 8 m (26 ft) in the bedrock; however, little salt occurs in the eolian sand. Historic aerial photographs, anecdotal reports from oil-lease operators, and tree-ring records indicate that the surrounding oak forest was largely established after 1935 and thus postdates the majority of surface damage at the site. Blackjack oaks adjacent to the salt scar have anomalously elevated chloride (>400 ppm) in their leaves and record the presence of NaCl-rich salt or salty water in the shallow subsurface. The geophysical measurements also indicate moderately elevated conductance beneath the oak forest adjoining the salt scar.

Here, we report on the effectiveness of a low-cost method of remediation of a combined spill of crude oil and brine in the Tallgrass Prairie Preserve in Osage County, Oklahoma. Specifically, we have used hay and fertilizer as amendments for remediation of both the oil and the brine. No gypsum was used. Three spills of crude oil plus produced water brine were treated with combinations of ripping, fertilizers and hay, and a downslope interception trench in an effort to demonstrate an inexpensive, easily implemented, and effective remediation plan. No statistically significant effect of treatment on the biodegradation of crude oil was, however observed. Total petroleum hydrocarbon (TPH) reduction clearly proceeded in the presence of brine contamination. The average TPH half-life considering all impacted sites was 267 days. The combination of hay addition, ripping, and a downslope interception trench was superior to hay addition with ripping or ripping plus an interception trench in terms of rates of sodium and chloride leaching from the impacted sites. Reductions in salt inventories (36 months) were 73% in the site with hay addition, ripping, and an interception trench, 40% in the site with hay addition and ripping only, and less than 3% in the site with ripping and an interception trench.

Geochemical data collected from nearby oil wells show that the produced water source is a Na-Ca-Cl brine ( approximately 150,000 mg/L total dissolved solids [TDS]), with relatively high concentrations of Mg, Sr, and NH (sub 4) , but low SO (sub 4) and H (sub 2) S. Results from the depleted OSPER A site show that the salts continue to be removed from the soil and surficial rocks, but degraded oil persists on the contaminated surface. Eventually, the bulk of inorganic salts and dissolved organics in the brine will reach the adjacent Skiatook Lake, a 4250-ha (10,501-ac) potable water reservoir. Repeated sampling of 44 wells show a plume of high-salinity water (2000-30,000 mg/L TDS) at intermediate depths that intersects Skiatook Lake and extends beyond the visibly impacted areas. No liquid petroleum was observed in this plume, but organic acid anions, benzene, toluene, ethylbenzene, and xylene (BTEX), and other volatile organic carbon (VOC) are present. The chemical composition of released brine is modified by sorption, mineral precipitation and dissolution, evapotranspiration, volatilization, and bacterially mediated oxidation-reduction reactions, in addition to mixing with percolating precipitation water, lake water, and pristine groundwater. Results show that only minor amounts of salt are removed by runoff, supporting the conclusion that significant amounts of salts from produced water and petroleum releases still remain in the soils and rocks of the impacted area after more than 65 yr of natural attenuation.

Absolute errors are estimated by comparison of paired measurements from collocated instruments. Spatial and temporal differences in absolute error were identified and are consistent with longitudinal distributions of NADP/NTN measurements and spatial differences in precipitation characteristics. The magnitude of error for calcium, magnesium, ammonium, nitrate, and sulfate concentrations, specific conductance, and sample volume is of minor environmental significance to data users. Data collected after a 1994 sample-handling protocol change are prone to less absolute error than data collected prior to 1994. Absolute errors are smaller during non-winter months than during winter months for selected constituents at sites where frozen precipitation is common. Minimum resolvable differences are estimated for different regions of the USA to aid spatial and temporal watershed analyses. Spatial and temporal characteristics and confidence limits associated with the overall absolute error in NADP/NTN measurements are identified and quantified.

The present experiments sought to determine whether or not in vitro solution concentration was an appropriate dose-metric for comparison to in vivo tissue levels for lipophilic compounds. To do so, the accumulation of the polychlorinated biphenyl (PCB) mixture Aroclor 1254 (A1254) or methylmercury (MeHg) was examined in three commonly utilized in vitro neuronal tissue models: nerve growth factor differentiated pheochromocytoma (PC12) cells, primary cultures of rat neocortical cells, and adult rat hippocampal slices. Tissues were exposed to A1254 (0.65 ppm) or to MeHg (0.0033-0.33 ppm) in serum-free media for 1 or 24 h. Total PCB or mercury accumulation was measured by dual column gas chromatography with electron capture detection or by cold vapor atomic absorption, respectively. PC12 cells accumulated 66.7 and 103.8 ppm PCBs after 1 and 24 h exposure to A1254. Neocortical neurons also accumulated significant concentrations of PCBs, but less so than PC12 cells. After 1 h exposure to 0.65 ppm A1254, slices contained 3.46 and 0.81 ppm PCBs when exposed in a static and perfused system, respectively. After 1 h exposure to 0.0033, 0.033, and 0.33 ppm MeHg, PC12 cells contained 0.3, 2.2, and 17.7 ppm mercury, respectively; after 24 h, PC12 cells contained 0.4, 2.8, and 21.9 ppm. Hippocampal slices accumulated 1.7 and 4.8 ppm mercury after 1 and 3 h exposure to 0.33 ppm MeHg. For comparison, mercury accumulation in rat fetal and pup brain tissue after maternal exposure [0, 0.1, 1.0, or 2.0 mg/kg/day MeHg from gestational day (GD) 6-15] ranged from 0.05 to 7.89 ppm in 0.1 mg/kg dose animals on postnatal day 10 and 2.0 mg/kg dose animals on GD16, respectively. These results demonstrate that accumulation of PCBs and MeHg in vitro is tissue-, time-, and concentration-dependent and indicates that tissue levels rather than exposure concentrations are a more appropriate metric for comparison of in vitro to in vivo effects.

It inhibits steroid synthesis via P450 modulation and acts as an androgen receptor (AR) antagonist, but its effects on male sexual differentiation have not been described. The purpose of the current study was to expand in vitro observations and to determine whether PZ affected sexual differentiation. PZ effects on AR-mediated gene expression were tested using a cell line (MDA-kb2) containing endogenous AR and stably transfected with an MMTV-luc reporter. PZ concentrations greater than 1 mu M caused a dose-dependent inhibition of dihydrotestosterone-induced gene expression. PZ also inhibited R1881 binding to the rat AR (IC sub(50) similar to 60 mu M). In vivo, pregnant rats received PZ by gavage from Gestational Day 14 to 18 at doses of 31.25, 62.5, 125, and 250 mg/kg of body weight per day. PZ delayed delivery in a dose-dependent manner and resulted in pup mortalities at the two highest doses. In male offspring, anogenital distance and body weight were slightly reduced at 3 days of age. Additionally, female-like areolas were observed at 13 days of age at frequencies of 31%, 43%, 41%, and 71% in the lowest-dose to highest-dose groups, respectively. Weights of androgen-dependent tissues showed dose-dependent reductions. Hypospadias and vaginal pouches were noted in all males treated with 250 mg/kg, whereas those defects were observed in 12.5% and 6.25%, respectively, of males treated with 125 mg/kg. Treatment did not affect age of preputial separation in animals without penile malformations. Despite severe malformations in males, no malformations were noted in females. Together, these results indicate that PZ alters sexual differentiation in an antiandrogenic manner.

Arsenic oxidation state and geochemical speciation were analyzed as a function of depth (two sampling sites) and surface distribution. These results were compared with intensive desorption/dissolution experiments performed in a pH stat reactor for samples from the site with the highest degree of As heterogeneity. The objectives of the study were to investigate the solid-phase geochemical As speciation, assess the speciation of As in solutions equilibrated with the solids under controlled pH (pH=4 or 6) and Eh (using hydrogen or air) environments, observe the effects of phosphate on the release of As into solution, and examine the effects of phosphate on metal mobility in the systems. Arsenic was predominantly found in the As(V) valence state, though there was evidence that As(III) and As(0) were present also. The dominant geochemical phase was scorodite (FeAsO sub(4)[sup].2H sub(2)O). The pH was controlled in the pH stat experiments by the addition of equinormal solutions of monoprotic (HNO sub(3)), diprotic (H sub(2)SO sub(4)), or triprotic (H sub(3)PO sub(4)) acids. For many of the divalent metal cations, solution concentrations greatly decreased in the presence of phosphate. Solutions were also analyzed for anions. Evidence exists for sulfate release into solution. More As was released into solution at lower pH. A slight increase in solution arsenate occurs with the addition of phosphate, but the risk posed from the increased desorption/dissolution of As must be weighed against the decrease in solution concentrations of many metals especially Pb. If tailings from this site underwent acidification (e.g., acid mine drainage), in situ sequestration of metals by phosphate could be combined with placement of subsurface permeable reactive barriers for capture of As to reduce the risk associated with arsenic and trace metal mobilization. Results from this study could be used in risk management plans for sites similar to the Pb smelter site examined here.

This study assessed the acute phototoxicity of the water accommodated fractions of weathered Alaska North Slope crude oil (ANS) to juvenile pink salmon, which are a heavily pigmented life stage. Fish in the highest ANS treatments exhibited melanosis, less mobility, reduced startle response, erratic swimming, and loss of equilibrium. Gills from fish exposed to ANS had elevated levels of hydroperoxides in oil-only, UV-only, and oil + UV treatments compared to control fish, which was indicative of increased lipid peroxidation in gill tissue. Under the test conditions of moderate salinity, low UV and high short-term oil exposure there were no indications of photoenhanced toxicity as assessed by elevation of mortality, behavioral impairment, or gill lipid peroxidation in oil + UV treatments. The results of this study suggest that pink salmon may be at less risk from photoenhanced toxicity compared to the translucent early-life stages of several other Alaska species.

TCDD exposure disrupts expression of epidermal growth factor (EGF) receptor, EGF, and transforming growth factor- alpha (TGF alpha ) in the palate and affects proliferation and differentiation of medial epithelial cells. EGF knockout embryos are less susceptible to the induction of CP by TCDD. This study used palate organ culture to examine the hypothesis that EGF enables a response to TCDD.

No agamospermous seeds were produced when both wind and insects were excluded from female cones; and the exclusion of wind-vectored pollen alone did not eliminate seed set, because insects were able to reach the cone. Based on enclosure pollination tests, each weevil pollinates an average 26.2 ovules per cone and each thrips 2.4 ovules per cone. These pollinators visited similar numbers of ovules per cone in fluorescent dye tests that traced insect movement through cones. Fluorescent dye granules deposited by Cycadothrips were concentrated around the micropyle of each visited ovule, the site of pollen droplet release, where pollen must be deposited to achieve pollination. In contrast, Tranes weevils left dye scattered on different areas of each visited ovule, indicating that chance plays a greater role in this system. Each weevil and 25 thrips delivered 6.2 and 5.2 pollen grains, respectively, on average, to each visited ovule per cone, based on examination of dissected pollen canals. In sum, the pollination potential of 25 Cycadothrips approximates that of one Tranes weevil.

Developmental and long-term exposures to these contaminants may pose a human health risk, especially to children. Previously, we demonstrated that polychlorinated biphenyls (PCBs), which are neurotoxic and structurally similar to PBDEs, perturbed intracellular signaling events, including calcium homeostasis and subsequent events such as protein kinase C (PKC), which are critical for the normal function and development of the nervous system. The objective of the present study was to test whether commercial PBDE mixtures (DE-71, a pentabrominated dipheyl ether mixture, and DE-79, a mostly octabromodiphenyl ether mixture) affected intracellular signaling mechanisms in a similar way to that of PCBs and other organohalogens, as an attempt to understand the common mode of action for these persistent chemicals. PKC translocation was studied by determining super(3)H-phorbol ester ( super(3)H-PDBu) binding in rat cerebellar granule cells, and calcium buffering was determined by measuring super(45)Ca super(2+) uptake by microsomes and mitochondria isolated from adult male rat brain (frontal cortex, cerebellum, and hippocampus). As seen with PCBs, DE-71 increased PKC translocation and inhibited super(45)Ca super(2+) uptake by both microsomes and mitochondria in a concentration-dependent manner. The effect of DE-71 on super(45)Ca super(2+) uptake seems to be similar in all three brain regions. Between the two organelles, DE-71 inhibited mitochondrial super(45)Ca super(2+) uptake to a greater extent than microsomal super(45)Ca super(2+) uptake. DE-79 had no effects on either neurochemical event even at 30 mu g/ml. Aroclor 1254 altered both events to a greater extent compared to DE-71 on a weight basis. When the results were compared on a molar basis, Aroclor 1254 altered PKC translocation and microsomal super(45)CaP super(2+) uptake to a greater extent than DE-71, however, Aroclor 1254 and DE-71 equally affected mitochondrial super(45)Ca super(2+) uptake. These results indicate that PBDEs perturbed intracellular signaling mechanisms in rat brain as do other organohalogen compounds and the efficacy between the commercial PCB and PBDE mixtures seem to vary with different endpoints.

As a physical resource transmitted along the trophic web, perturbations in protein nitrogen metabolism may also help resolve issues concerning the effects of contaminants on organisms and their consequential hierarchical linkages in ecotoxicology. Snowy egret nestlings (Egretta thula) fed mercury-contaminated diets of constant nitrogen isotope composition exhibited increased relative delta super(15)N values in whole liver (p = 0.0011) and the acid-soluble fraction (ASF) of the liver (p = 0.0005) when compared to nestlings fed a reference diet. When nitrogen isotope data were adjusted for the source term of the diet, liver mercury concentrations corresponded with both whole liver relative super(15)N enrichment (r super(2) = 0.79, slope 0.009, p < 0.0001) and relative super(15)N enrichment in the acid-soluble fraction of the liver (r super(2) = 0.85, slope 0.026, p < 0.0001). Meanwhile, significant differences were not observed in hepatic levels of the metal-binding peptides metallothionein and glutathione despite a nearly 3-fold difference in liver mercury content. Because increases in tissue delta super(15)N values result from increased rates of protein breakdown relative to synthesis, we propose that the increased relative liver delta super(15)N values reflect a shift in protein metabolism. The relationship between ASF and mercury was significantly stronger (p < 0.0001) than that for whole liver, suggesting that the relationship is driven by an increase in bodily derived amino acids in the acid-soluble, free amino acid pool.

In contrast, it has been shown that ozone is a more effective disinfectant than chlorine. US EPA is currently evaluating a treatment rule, which addresses the control of C. parvum oocysts in drinking water. The use of Ct (average disinfectant concentration multiplied by characteristic contact time) values is being considered as one of the options for demonstrating adequate control of this microbial contaminant. The purpose of this study is to incorporate the variability in inactivation kinetics among different lots of oocysts and to develop a statistical model for, Ct, based on first-order delayed Chick-Watson inactivation kinetics. A Bayesian approach is used to estimate the delayed Chick-Watson kinetic parameters. A log-linear regression analysis is then used to represent the effect of temperature on the resulting kinetic parameters. The overall model developed in this study provides an approach for water utilities and regulatory agencies to decide on the level of safety needed when developing treatment requirements for the inactivation of C. parvum oocysts with ozone as part of broader risk assessment considerations.

Perspectives arising from short-term, small-scale, local experiments are rarely tested over larger scales and longer time frames. Regression analysis and aerial photography were used to assess the relative importance of land-use history (fire and grazing), rainfall and initial woody cover (woody cover at the beginning of a sample period relative to the range of woody cover expressed within a land type) in accounting for rates of change in overstorey and understorey cover between the 1940s and 1990s in central Queensland, Australia. Analyses included 279 site-period combinations representing five semi-arid eucalypt savanna land-types within a 125 755 km super(2) region. Fire and grazing variables provided no explanatory power. In general, relative rainfall (rainfall for a given period standardized against mean annual rainfall) was positively related and initial woody cover negatively related to rates of change in both the overstorey and the understorey. The interaction between rainfall and initial woody cover was significant, reflecting the fact that increases in cover coincided with low initial cover when rainfall is higher than average, whereas decreases in cover typically occurred with high initial cover, regardless of rainfall. On average, overstorey and understorey cover increased over the second half of the 20th century. This pattern is consistent with the first half of the 20th century having more intense droughts and being drier overall than the relatively wet second half. The findings highlight the primary importance of interactions between rainfall fluctuations and density dependence as determinants of large-scale, long-term woody plant cover dynamics in savannas subject to large rainfall excess and deficit over multiyear time-scales.

The default procedure for setting AEGL values across durations when applicable data are unavailable involves estimation based on Haber's rule, which has an underlying assumption that cumulative exposure is the determinant of toxicity. For acute exposure to trichloroethylene (TCE), however, experimental data indicate that momentary tissue concentration, and not the cumulative amount of exposure, is important. We employed an alternative approach to duration adjustments in which a physiologically-based pharmacokinetic (PBPK) model was used to predict the arterial blood concentrations [TCE sub(a)] associated with adverse outcomes appropriate for AEGL-1, -2, or -3-level effects. The PBPK model was then used to estimate the atmospheric concentration that produces equivalent [TCE sub(a)] at each of the AEGL-specific exposure durations. This approach yielded [TCE sub(a)] values of 4.89 mg-l for AEGL-1, 18.7 mg-l for AEGL-2, and 310 mg-l for AEGL-3. Duration adjustments based on equivalent target tissue doses should provide similar degrees of toxicity protection at different exposure durations.

The Tracking and Analysis Framework (TAF) model was originally designed to evaluate the biotic, economic, and health effects of acid deposition. The TAF model developed in our study was used to assess the biotic effects of different levels of sulfate deposition resulting from alternative emissions scenarios. The aquatic portion of the model is based on a lumped-parameter watershed chemistry model, MAGIC (Model of Acidification of Groundwater in Catchments). The original TAF model was built by calibrating MAGIC to 33 lakes in the Adirondack Mountains. We calibrated MAGIC to 78 HELM lakes, and built reduced-form models from these MAGIC predictions. We evaluated TAF predictions of acid neutralizing capacity (ANC), a fish acid stress index (ASI), and the probability of fish presence in 2030 for four different SO sub(2) emissions-reduction scenarios. The most dramatic emissions reduction scenario produced only modest increases in mean ANC (16.8 mu eq/L plus or minus 7.9 mu eq/L) and slight increases in mean predicted probability of presence of acid-sensitive fish (0.07 plus or minus 0.09) across all lakes. However, a small number of lakes were predicted to have more substantial increases in ANC and improvements in other conditions for acid-sensitive fish. Our results reflect the reality that many of the high elevation lakes of Maine historically had low ANC and that some were even acidic in pre-industrial times. Thus, 'recovery' for most of the high elevation lakes of Maine will be modest under any scenario of reduced acidic deposition.

Chlorpyrifos inhibits acetylcholinesterase activity, resulting in central and peripheral stimulation of central cholinergic pathways involved in blood pressure regulation. The spontaneously hypertensive rat has been shown to be more sensitive to central cholinergic stimulation. Therefore, we hypothesized that these rats would be more susceptible and sustain a greater hypertensive response when exposed to chlorpyrifos. Heart rate, cardiac contractility, core temperature, and blood pressure were monitored by radiotelemetry in SHRs and their Wistar Kyoto (WKY) normotensive controls following exposure to chlorpyrifos (10 mg/kg or 25 mg/kg, orally). Baseline blood pressure of SHRs was similar to 35 mmHg above that of WKYs prior to dosing. SHRs exhibited a greater and more sustained elevation in diastolic, mean and systolic blood pressure following exposure to 25 mg/kg of chlorpyrifos. The rise in blood pressure lasted for similar to 56 hours in SHRs compared to similar to 32 hours in WKYs. Chlorpyrifos also led to a prolonged elevation in daytime heart rate in both strains. There was a transient elevation in cardiac contractility in both strains lasting similar to 7 hr after exposure to chlorpyrifos. The hypothermic response to chlorpyrifos was similar in magnitude and duration for both strains. Plasma cholinesterase activity measured 4 hr after exposure to 25 mg/kg chlorpyrifos was inhibited to similar to 40% of control levels in both strains. Using the SHR strain as a model to study susceptible populations, the data suggest that individuals with a genetic predisposition to hypertension may be more susceptible from exposure to organophosphate-based insecticide, as manifested by an exacerbated hypertensive response.

During the July 2001 sampling period, the use of KI and KCl denuders placed upstream to remove ozone and reactive gaseous mercury, Hg super(2+) sub((g)), resulted in more particulate mercury (maximum 33 pg m super(-3)) on a denuded filter when compared to an undenuded one. Additionally, a KCl denuded quartz filter also showed more particulate mercury (maximum 12 pg m super(-3)) compared to an undenuded filter when ozone concentrations were most elevated. Further sampling in July 2002 used a repeated sampling design and resulted in more particulate mercury on undenuded filters when compared to denuded ones. Conditions in July 2001 were characterized by elevated concentrations of ozone during which there were three ozone action days declared by the State of Michigan whereas ozone concentrations in July 2002 were 22% lower. One possible explanation for the observations may be that elemental mercury, Hg super(0) sub((g)), is oxidized to reactive gaseous mercury, Hg super(2+) sub((g)), during sampling leading to an artifact. The potential for this type of artifact may be greater during periods of high photochemical activity and this must be considered when sampling during the warmer seasons when high levels of oxidants are likely to be present in an urban atmosphere.

We analyzed Bacteroidales 16S rRNA gene sequences from the feces of eight hosts: human, bovine, pig, horse, dog, cat, gull, and elk. Recovered sequences did not match database sequences, indicating high levels of uncultivated diversity. The analysis revealed both endemic and cosmopolitan distributions among the eight hosts. Ruminant, pig, and horse sequences tended to form host- or host group-specific clusters in a phylogenetic tree, while human, dog, cat, and gull sequences clustered together almost exclusively. Many of the human, dog, cat, and gull sequences fell within a large branch containing cultivated species from the genus BACTEROIDES: Most of the cultivated Bacteroides species had very close matches with multiple hosts and thus may not be useful targets for fecal source identification. A large branch containing cultivated members of the genus Prevotella included cloned sequences that were not closely related to cultivated Prevotella species. Most ruminant sequences formed clusters separate from the branches containing Bacteroides and Prevotella species. Host-specific sequences were identified for pigs and horses and were used to design PCR primers to identify pig and horse sources of fecal pollution in water. The primers successfully amplified fecal DNAs from their target hosts and did not amplify fecal DNAs from other species. Fecal bacteria endemic to the host species may result from evolution in different types of digestive systems.

Sustainability of an ecosystem refers to the robustness of a preferred dynamic regime to human and natural disturbances. Ecosystems under perturbations of varying regularity and intensity can either remain within the current regime or transition into the neighbourhood of a regime with different (viz. less desirable) characteristics. The Fisher Information index we develop is based on the probability of finding the system in a particular state. We apply the index to a 10-compartment food web model with five functional groups: detritus, primary producers, herbivores, carnivores, and an omnivore. Fisher Information is shown to be sensitive to transients in model generated data. Such transients can be indicative of a transition to a new dynamic regime. Early detection of transitions to undesirable regimes may permit management intervention.

6391690 AB - The relative sensitivity of rats and humans to volatile organic compounds (VOCs) such as toluene (TOL) and perchloroethylene (PERC) is unknown and adds to uncertainty in assessing risks for human exposures to VOCs. Recent studies have suggested that ion channels, including nicotinic acetylcholine receptors (nAChRs), are targets of TOL effects. However, studies comparing TOL effects on human and rat ligand-gated ion channels have not been conducted. To examine potential toxicodynamic differences between these species, the sensitivity of human and rat nAChRs to TOL was assessed. Since PERC has similar effects, in vivo, to TOL, effects of PERC on nAChR function were also examined. Two-electrode voltage-clamp techniques were utilized to measure acetylcholine-induced currents in neuronal nAChRs ( alpha 4 beta 2, alpha 3 beta 2, and alpha 7) expressed in Xenopus oocytes. PERC (0.065 mM) inhibited alpha 7 nAChR currents by 60.1 +/- 4.0% (human, n = 7) and 40 +/- 3.5% (rat, n = 5), and inhibited alpha 4 beta 2 nAChR currents by 42.0 +/- 5.2% (human, n = 6) and 52.2 +/- 5.5% (rat, n = 8). Likewise, alpha 3 beta 2 nAChRs were significantly inhibited by 62.2 +/- 3.8% (human, n = 7) and 62.4 +/- 4.3% (rat, n = 8) in the presence of 0.065 mM PERC. TOL also inhibited both rat and human alpha 7, alpha 4 beta 2, and alpha 3 beta 2 nAChRs. Statistical analysis indicated that although there was not a species (human vs. rat) difference with PERC (0.0015-0.065 mM) or TOL (0.03-0.9 mM) inhibition of alpha 7, alpha 4 beta 2, or alpha 3 beta 2 nAChRs, all receptor types were more sensitive to PERC than TOL. These results demonstrate that human and rat nACh receptors represent a sensitive target for VOCs. This toxicodynamic information will help decrease the uncertainty associated with animal to human extrapolations in the risk assessment of VOCs.

Because of this and the fact that no toxicological data were available for this compound, which is structurally similar to the rodent carcinogen 1,3-dichloropropene (1,3-DCPe), 1,1-DCPe was placed on the Contaminant Candidate List of the US Environmental Protection Agency. Consequently, we have performed a hazard characterization of 1,1-DCPe by evaluating its mutagenicity in the Salmonella assay and its DNA damaging (comet assay) and apoptotic (caspase assay) activities in human lymphoblastoid cells. In Salmonella, 1,1-DCPe was not mutagenic in strains TA98, TA100, TA1535, or TA104 +/-S9 mix. However, it was clearly mutagenic in strain RSJ100, which expresses the rat GSTT1-1 gene. 1,1-DCPe did not induce DNA damage in GSTT1-1-deficient human lymphoblastoid cells, and it induced apoptosis in these cells only at 5mM. Consistent with its mutagenesis in RSJ100, 1,1-DCPe reacted with glutathione (GSH) in vitro, suggesting an addition-elimination mechanism to account for the detected GSH conjugate. 1,1-DCPe was ~5000 times more mutagenic than its ethene congener 1,1-dichloroethylene (1,1-DCE or vinylidene chloride). Neither 1,1-DCE nor 1,3-DCPe showed enhanced mutagenicity in strain RSJ100, indicating a lack of activation of these congeners by GSTT1-1. Thus, 1,1-DCPe is a base-substitution mutagen requiring activation by GSTT1-1, possibly involving the production of a reactive episulfonium ion. This bioactivation mechanism of 1,1-DCPe is different from that of its congeners 1,1-DCE and 1,3-DCPe. The presence of 1,1-DCPe in source waters could pose an ecological or human health risk. Occurrence data for 1,1-DCPe in finished drinking water are needed to estimate human exposure to, and possible health risks from, this mutagenic compound.

The impact of the forest growth on streamflow of the basin was assessed using statistical trend analysis. Annual maximum daily flow, annual minimum 5-day flow, and annual total runoff decreased by 55.8, 75.8, and 39.6%, respectively, over the period. However, the annual maximum 6-day, annual minimum 41-day, and annual total precipitation, respectively associated with annual maximum daily flow, annual minimum 5-day streamflow, and annual total runoff did not decrease. Annual and monthly temperature, which evapotranspiration positively related to, did not increase except in January. This demonstrates that the forest growth is responsible for the decrease in all these three flow regimes. The increase in evapotranspiration due to the forest growth resulted in the decrease in both total runoff and low flow. Thus, it seems that forest can hardly function to both reduce flood peaks during flood periods and increase water supply during drought periods.

AN - 67922336; 15868159 AB - Ten oil spill bioremediation products were tested in the laboratory for their ability to enhance biodegradation of weathered Alaskan North Slope crude oil in both freshwater and saltwater media. The products included nutrients to stimulate inoculated microorganisms, nutrients plus an oil-degrading inoculum, nutrients plus compounds intended to stimulate oil-degrading activity, or other compounds intended to enhance microbial activity. The product tests were undertaken to evaluate significant modifications in the existing official United States Environmental Protection Agency (EPA) protocol used for qualifying commercial bioremediation agents for use in oil spills. The EPA protocol was modified to include defined formulas for the exposure waters (freshwater, saltwater), a positive control using a known inoculum and nutrients, two negative controls (one sterile, the other inoculated but nutrient-limited), and simplified oil chemical analysis. Three analysts conducted the product test independently in each type of exposure water in round-robin fashion. Statistical tests were performed on analyst variability, reproducibility, and repeatability, and the performance of the various products was quantified in both exposure media. Analysis of variance showed that the analyst error at each time-point was highly significant (P values ranged from 0.0001 to 0.008, depending on water type and oil fraction). In the saltwater tests, six products demonstrated various degrees of biodegradative activity against the alkane fraction of the crude oil and three degraded the aromatic hydrocarbons by >10%. In the freshwater tests, eight products caused >20% loss of alkane hydrocarbons, of which five degraded the alkanes by >50%. Only four products were able to degrade polycyclic aromatic hydrocarbons (PAHs) by >20%, one of which caused 88% removal. However, when the variability of the analysts was taken into consideration, only one of the ten products was found to yield significant percent removals of the PAH fraction and only in freshwater. Viable microorganism population analysis (most-probable-number method) was also performed on every sample by each operator to measure the changes in aromatic and alkane hydrocarbon-degrading organism numbers. In general, little evidence of significant growth of either alkane- or PAH-degraders occurred among any of the ten products in either the saltwater or freshwater testing.

AN - 67821116; 15305170 AB - To reduce the uncertainty associated with current estimates of children's exposure to pesticides by dermal contact and indirect ingestion, residue transfer data are required. Prior to conducting exhaustive studies, a screening study to identify the important parameters for characterizing these transfers was designed. A fluorescence imaging system was developed (Ivancic et al., in press) to facilitate collection of surface residue transfer data for repeated contacts. Next, parameters that affect residue transfer from surface-to-skin, skin-to-other objects, and skin-to-mouth were evaluated using the imaging system and the fluorescent tracer riboflavin as a surrogate for pesticide residues. Riboflavin was applied as a residue to surfaces of interest. Controlled transfer experiments were conducted by varying contact parameters with each trial. The mass of a tracer transferred was measured and the contact surface area estimated using video imaging techniques. Parameters evaluated included: surface type, surface loading, contact motion, pressure, duration, and skin condition. Transfers both onto, and off of, the hand were measured. To efficiently identify parameter changes resulting in significant effects, the Youden ruggedness test was used to select the combination of parameters varied in each contact trial. In this way, more than one parameter could be varied at a time and the number of trials required was minimized. Results of this study showed that surface loading and skin condition (significant at alpha=0.05) are among the important parameters for characterizing residue transfers of riboflavin. Duration of contact within the time range investigated does not have a significant effect on transfer of this tracer. Results of this study demonstrate the potential for collecting dermal transfer data using the Ivancic et al. fluorescence imaging system and provide preliminary data to reduce uncertainty associated with estimating dermal exposures resulting from contact with residue-contaminated surfaces. These data will also aid in determining what additional residue transfer data should be collected and what type of microactivity data are needed to estimate dermal and indirect ingestion exposure to residues on household surfaces.

AN - 67803164; 15878140 AB - This Reflections article considers the problems associated with the various extrapolations that are required for the estimation of human cancer risks from exposure to environmental carcinogens at low doses. These include extrapolation between species (particularly rodent to human), from responses at high doses to those at low doses, and among different stages of life. Reductions in uncertainty in risk estimates are closely coupled to the ability to conduct reliable extrapolations. The best way forward appears to be the use of data on mechanisms of carcinogenesis to develop bioindicators of responses related to the pathway to tumor formation. Such an approach is proposed based on the phenotypes represented by the six acquired characteristics forming the Hanahan-Weinberg model for carcinogenesis (The Hallmarks of Cancer). In addition, approaches can be established that use the Hanahan-Weinberg model as the basis for the collection and/or analysis of microarray or similar data. The reduction in reliance on default options and safety factors in the risk assessment process is a real possibility.

AN - 67783048; 15866759 AB - Many reports in the literature suggest that long-term exposure to styrene may exert a variety of effects on the nervous system, including increased choice reaction time and decreased performance of color discrimination and color arrangement tasks. Sufficient information exists to perform a meta-analysis of these observations quantifying the relationships between exposure (estimated from biomarkers) and effects on two measures of central nervous system function: reaction time and color vision. To perform the meta-analysis, we pooled data into a single database for each end point. End-point data were transformed to a common metric of effect magnitude (percentage of baseline). We estimated styrene concentration from biomarkers of exposure and fitted linear least-squares equations to the pooled data to produce dose-effect relationships. Statistically significant relationships were demonstrated between cumulative styrene exposure and increased choice reaction time as well as increased color confusion index. Eight work-years of exposure to 20 ppm styrene was estimated to produce a 6.5% increase in choice reaction time, which has been shown to significantly increase the probability of automobile accidents. The same exposure history was predicted to increase the color confusion index as much as 1.7 additional years of age in men.

AN - 67713749; 15814488 AB - Phosgene (COCl(2)) exposure affects an influx of inflammatory cells into the lung, which can be reduced in an animal model by pretreatment with colchicine. Inflammation in the respiratory tract can be associated with an increase in airway hyperreactivity. We tested the hypotheses that (1) phosgene exposure increases airway reactivity and (2) colchicine can decrease this elevation. Sprague Dawley rats (70 d old; male) were exposed to 1 ppm COCl(2) for 1 h. Airway reactivity was tested at 0, 4, and 24 h postexposure by infusing anesthetized animals intravenously with acetylcholine and assessing expiratory resistance and dynamic compliance. Immediately and 4 h postexposure, a significant change in expiratory resistance and dynamic compliance was observed in those animals exposed to COCl(2), while at 24 h this response was greater. A second experiment was performed in rats pretreated with colchicine (1 mg/kg) or saline given intraperitoneally, exposed to 1 ppm COCl(2) for 1 h, with both expiratory resistance and dynamic compliance assessed at 24 h. After exposure, cell differentials and protein in lavage were also quantitated. The results indicate that colchicine decreased neutrophil influx, protein accumulation, and changes in both expiratory resistance and dynamic compliance after COCl(2) exposure. Colchicine may affect injury and changes in expiratory resistance and dynamic compliance by diminishing the incursion of inflammatory cells, but other properties of this medication may also be responsible for the observed results.

Knowledge of the mineralogy of scales in these pipes is key to modeling this dissolution. The traditional method of determining their mineralogy has been bulk X-ray diffraction (XRD). However, the minerals in these scales are often heterogeneously distributed in layers, and identification of each layer is difficult because they are thin and difficult to separate. There is also horizontal heterogeneity and some minerals are only present in low concentrations or occur as amorphous phases, which limit the use of XRD. Micro-Raman spectroscopy is a powerful complement to XRD because it allows mineral identification of micron-sized individual grains and can identify amorphous phases. This study evaluates the applicability of micro-Raman spectroscopy for identifying and mapping the mineralogy of the layers and surface topology of lead pipe scales. One lead pipe and its scales, provided by Utility X, was used for this study. This pipe was examined with a stereomicroscope to identify the spatial arrangements of the mineral phases. The scale minerals displayed a great deal of variation both vertically and horizontally. Scale deposits from portions of the pipe were harvested as a single sample for pressed-powder XRD analyses. The mineralogy determined by XRD included: hydrocerussite, (Pb3(CO (sub 3) ) (sub 2) (OH) (sub 2) ), cerussite (PbCO (sub 3) ), litharge (PbO), and massicot (PbO). Minor amounts of plattnerite (PbO (sub 2) ) were also detected. Plumbonacrite (Pb (sub 10) O(CO (sub 3) ) (sub 6) (OH) (sub 6) ) and/or quartz may also be present. Micro- Raman spectra confirmed the presence of these same minerals. In addition it showed that these minerals occur in radial patterns, with hydrocerussite at the center, followed by massicot, then litharge all of which is surrounded by plattnerite. The large number of Pb phases shows that these pipes do not constitute an equilibrium system. The Raman mapping suggests the evolution in Pb chemistry with time that may reflect changes in water treatment practices.

The U.S. Environmental Protection Agency (EPA) has developed a ground-based optical remote-sensing method that enables direct measurement of fugitive emission flux from large area sources. Open-path Fourier transform infrared spectroscopy (OP-FTIR) has been the primary technique for acquisition of pollutant concentration data used in this emission measurement method. For a number of environmentally important compounds, such as ammonia and methane, open-path tunable diode laser absorption spectroscopy (OP-TDLAS) is shown to be a viable alternative to Fourier transform spectroscopy for pollutant concentration measurements. Near-IR diode laser spectroscopy systems offer significant operational and cost advantages over Fourier transform instruments enabling more efficient implementation of the measurement strategy. This article reviews the EPA's fugitive emission measurement method and describes its multipath tunable diode laser instrument. Validation testing of the system is discussed.

Atmospheric deposition monitoring and source attribution data were used along with simulation models to calculate Hg buildup in the subwatershed soils, its subsequent runoff loading and delivery through the tributaries, and its ultimate fate in the mainstem river. The terrestrial model calculated annual watershed yields for total Hg ranging from 0.7 to 1.1 ug/m2. Results suggest that approximately two-thirds of the atmospherically deposited Hg to the watershed is returned to the atmosphere, 10% is delivered to the river, and the rest is retained in the watershed. A check of the aquatic model results against survey data showed a reasonable agreement. Comparing observed and simulated total and methylmercury concentrations gave root mean square error values of 0.26 and 0.10 ng/L, respectively, in the water column, and 5.9 and 1 ng/g, respectively, in the upper sediment layer. Sensitivity analysis results imply that mercury in the Ochlockonee River is dominated by watershed runoff inputs and not by direct atmospheric deposition, and that methylmercury concentrations in the river are determined mainly by net methylation rates in the watershed, presumably in wetted soils and in the wetlands feeding the river.

We analyzed the stable isotope signatures of benthos (predominantly Diporeia spp.) and plankton from Lake Superior habitats ranging from 5 m to 300 m depth. Neither delta super(15)N nor delta super(13)C of plankton from the upper 50 m water column varied with station depth. Benthos were super(13)C-enriched at stations < 40 m depth, probably reflecting increased dietary importance of benthic algae. Diporeia exhibited a systematic increase in delta super(15)N with depth, described by the equation delta super(15)N = -4.37 + 1.74*ln(depth). We believe that this phenomenon is due to decomposition and release of the lighter N isotope during sedimentation of Diporeias principal food source, detrital plankton. These contrasting patterns in benthic and planktonic food web relationships hold implications for understanding niche breadth and resource use by different fishes, interpretation of stable isotope data from deep systems, and understanding the nature of nearshore and offshore habitats in the Great Lakes.

The EPA Ecosystems Research Division lab supports this commitment in partnership with others. In this framework investigators are developing a beach forecasting tool known as Visual Beach. The overall vision is an integrated approach to modeling bacteria concentrations on beaches, combining empirical and physics-based methodologies and models. Such capabilities are presented in a Windows-based application including data acquisition and graphical tools, e.g., weather forecasts, satellite imagery, GIS, and biological and physical monitoring data, for conceptualizing and mitigating beach accessibility problems. In 2005 empirical statistical approaches to beach bacteria prediction will be developed. The empirical model is based on manual techniques for assessing predictor data (antecedents, stresses) developed by Francy at the USGS, and other investigators. The software is intended to be accessible to most small offices concerned with issuing beach advisories and closures. This work describes Visual Beach efforts to date.

The LMMBP included a eutrophication model (LM3-EUTRO) to describe carbon production resulting from phytoplankton dynamics. While the eutrophication model is capable of simulating internal carbon loads, greater trophic level resolution to evaluate ecosystem impacts of external perturbations such as invasion of exotic species is required. A Lake Michigan Ecosystem Model (LM-ECO) that included a more detailed description of trophic levels and their interactions was developed as an enhanced version of the existing LM3-EUTRO model for Lake Michigan. The LM-ECO model constitutes a first step toward a comprehensive Lake Michigan ecosystem productivity model to investigate ecosystem-level responses and effects within the lower food web of the lake. The LM-ECO model was successfully applied to simulate the effect of the invasive species Bythotrephes cederstroemii on zooplankton abundance as indicated by field data collected during the 1994-1995 LMMBP.

A set of 12 "Level 1 substances" were selected for immediate action, and significant emission reductions have been achieved. As local sources are reduced the contribution of loadings to the Great Lakes from distant locations by atmospheric transport may become the controlling factor that determines the rate of reduction of contaminant levels in the Lakes. We have applied two multimedia mass balance models based on the Berkeley-Trent (BETR) model framework to calculate the efficiency of atmospheric transport and deposition to the Lakes for emissions of the Level 1 substances in different regions of North America and globally. The model analysis allows the Level 1 substances to be categorized as local, continental or global-scale management problems. When emission inventories are available, the model calculations can be used to estimate the contribution of emissions in different locations to atmospheric deposition fluxes to the Lakes. Using individual PCB congeners as a case study we find evidence that the contribution of global sources to the depositional flux of PCBs to the Lakes is increasing, but that local and continental sources still dominate total loadings to the Lakes.

The organomercury bromide derivatives were separated by capillary chromatography, passed through a pyrolysis oven to convert them to elemental mercury and transported with argon carrier gas to the atomic fluorescence spectrometer. Samples analyzed using this method included Lake Michigan whole forage fish and methyl/ethyl mercury dosed Kestrels (sparrow hawk). Kestrel tissue methyl mercury concentrations ranged from the method detection limit of 0.30 ng/g to 110,000 ng/g. Lake Michigan forage fish methyl mercury concentrations ranged from 7.4 ng/g to 81 ng/g. The average certified reference material recoveries for TORT-2 and DORM-2 were 99 % and 99% respectively. Kestrel tissue duplicates averaged 9.0 % relative difference. Forage fish duplicates averaged 10 % relative difference. This method offers high sensitivity and the ability to separate organomercury species, including ethyl mercury, providing an alternative to the ethylation-purge-trap method.

Appendix A of MILaMP discusses the use of sampling location, fish species (including fish diet), and specific pollutants to distinguish between critical pollutants causing an impairment in open water and pollutants of concern causing an impairment in relatively local areas. This distinction may lead to a delineation of management response between lakewide (multi-state and/or federal) for critical pollutants and local (state and/or local) for pollutants of concern. MILaMP also attempts to identify a pollutant watch list in an effort to prevent additional pollutants from becoming critical pollutants. This is an adaptive management work-in- progess, and does not represent final U.S. Environmental Protection Agency policy.

During most years, measurements are made during spring and summer survey limited to the open waters of the lakes. During these years, the Great Lakes have responded to changes in loadings and other factors, as documented in the long-term nutrient data. Total phosphorus has decreased in all lakes except Erie, while chloride and nitrate plus nitrite appear to be increasing. The results of the twenty years of monitoring will be presented, along with results of more recent, particulate nutrient monitoring.

The chemical is applied primarily to corn crops in the basin to control weeds, and was selected for study under the Lake Michigan Mass Balance Project. Modeling was conducted using our 41 segment WASP-based LM2-Toxic (Atrazine) model. Model calibration in hind-cast runs suggest that the chemical is persistent (half-life approximately equal to 77 years) in the oligotrophic lake. The model accounts for various processes including volatilization, absorption, and internal decay. Loading estimates of atmospheric wet deposition and runoff from farm fields were included in the model framework. Advective flows and exchanges in the model were derived from the hydrodynamic model, Princeton Ocean Model. Long term model predictions of atrazine in the lake will be shown under various loading scenarios. In addition, the model will demonstrate how a Total Maximum Daily Load (TMDL) may be calculated. The published results of two other atrazine models on Lake Michigan that predict much shorter atrazine half-lives in the lake will be compared to the results of LM2-TOXIC (Atrazine).

Each AOC has an active local committee working on a remedial action plan (RAP) to restore their AOC. For many years the RAPs focused on any activity that might improve local conditions. However, since there were so many problems, delisting was deemed too far off to even consider. The release of the US Policy Committees document, Delisting Principles and Guidelines, opened the door to using incremental delisting by beneficial use impairment (BUI) or by subwatershed as a better measure of RAP progress. This led Ohio EPA to develop minimal targets that the State would accept to support delisting. Each target was based on IJC criteria and existing State rules, regulations, policies or guidelines, as applicable. When no State policies were available, guidance was offered on how to conduct an assessment for the RAP to develop a target specific to their AOC. The Ohio RAPs are currently using these targets to reassess the Stage 1 BUI assessments to determine which BUIs or subwatersheds may be candidates for delisting or re-designation as "in recovery." This approach has already led to the re-designation of the fish tumor/deformity BUI in the Black River AOC from impaired to "in recovery." Progress inspires renewed interest.

In order to evaluate next steps for the program beyond 2006, the GLBTS has undertaken a review of the level 1 PBTs in the basin, including an analysis of levels and trends in Great Lakes environmental media and biota using currently available data; current use, consumption and emissions; and further opportunities to reduce these substances in the basin. This presentation will present the results of this review and provide an outlook for the future of the GLBTS.

We contrasted assessments using community metrics for each taxa group selected to be diagnostic of the two large-scale stressor gradients identified in this ecoregion: discharges from historical hardrock metal mines and agriculture, particularly pasturing of livestock. While principal components analysis (PCA) extracted axes from the metrics for all three assemblages correlated with increased metal concentrations, the axes differed in their sensitivity to different environmental gradients. Two axes extracted from the fish metrics were correlated with dissolved metals, suspended solids, and sediment embeddedness or with sediment metals. Two axes extracted from the macroinvertebrate metrics partially separated these two stressor gradients, while the single correlated axis extracted from the periphyton metrics did not. The second macroinvertebrate PCA axis was correlated with an environmental gradient correlated both with agricultural effects and with stream size, as were the second and third periphyton PCA axes. The third fish PCA axis was correlated with stream size and slope, but was not sensitive to agricultural effects. Fish, macroinvertebrates, and periphyton differ in their sensitivity to different stressors, and combining metrics for these assemblages into a mixed assemblage index of biotic integrity may increase the utility of the multimetric approach to diagnose environmental stressors at impaired reaches.

The benthic diffusive boundary layer inside a cylindrical chamber commonly deployed for in situ measurements of sediment oxygen demand is studied. In a series of laboratory experiments, the SOD is measured with the chamber operated in both continuous flow and batch modes, and a microelectrode is employed to measure the near bed dissolved oxygen (DO) profile for different chamber flows and sediment types. The dependence of the diffusive boundary layer thickness and the sediment-water mass transfer coefficient on the hydraulic parameters are quantified. Using the derived mass transfer coefficient, it is shown that for a given sediment type, the SOD is a function of the bulk DO concentration and chamber flowrate. The theoretical predictions are validated by both laboratory and field SOD data.

Stoermer to the Study of Great Lakes Diatoms: An Introduction AN - 19290732; 7183034 AB - Progress in the understanding of systematics, ecology, and ecosystem relationships of Great Lakes algal and diatom assemblages, as gauged against this fields Great Lakes history, is largely attributable to the devoted career of Dr. Eugene F. Stoermer. Through 40 years of scholarly investigation, Dr. Stoermer has conducted research in each of the Great Lakes and has contributed over 100 peer-reviewed journal publications, book chapters and reports. His contributions are recognized in the application of numerous field methods and interpretive techniques; thematic investigations; and through tireless mentoring. Various applications, techniques, and approaches include diatom morphology and systematics, quantitative algal plankton techniques, planktonic algae and diatom ecology, specialized benthic and sediment investigations, historical analyses, paleolimnology, evolution, image analysis, and statistical methods. Directed thematic studies regarding eutrophication theory, silica depletion, chloride impacts, habitat preference delineation, and exotic species are of particular merit. Various aspects of these approaches and techniques will be highlighted using Lake Huron as an example.

This has emerged as an issue for inorganic arsenic (iAs), because both its trivalent and pentavalent methylated metabolites have unique toxicities; the methylated trivalent metabolites also exhibit greater potency than trivalent inorganic arsenic (arsenite, As super(III)) for some endpoints. In this study, the time-course tissue distributions for iAs and its methylated metabolites were determined in blood, liver, lung, and kidney of female B6C3F1 mice given a single oral dose of 0, 10, or 100 mu mol As/kg (sodium arsenate, As super(V)). Compared to other organs, blood concentrations of iAs, mono- (MMA), and dimethylated arsenic (DMA) were uniformly lower across both dose levels and time points. Liver and kidney concentrations of iAs were similar at both dose levels and peaked at 1 h post dosing. Inorganic As was the predominant arsenical in liver and kidney up to 1 and 2 h post dosing, with 10 and 100 mu mol As/kg, respectively. At later times, DMA was the predominant metabolite in liver and kidney. By 1 h post dosing, concentrations of MMA in kidney were 3- to 4-fold higher compared to other tissues. Peak concentrations of DMA in kidney were achieved at 2 h post dosing for both dose levels. Notably, DMA was the predominant metabolite in lung at all time points following dosing with 10 mu mol As/kg. DMA concentration in lung equaled or exceeded that of other tissues from 4 h post dosing onward for both dose levels. These data demonstrate distinct organ-specific differences in the distribution and methylation of iAs and its methylated metabolites after exposure to As super(V) that should be considered when investigating mechanisms of arsenic-induced toxicity and carcinogenicity.

This model contains both toxicokinetic and toxicodynamic components. One advantage of the EDR model will be its ability to relate in vitro effects of solvents on cellular ion channels (putative targets) to in vivo effects, using a combination of physiologically-based toxicokinetic (PBTK) modeling (to estimate VOC concentrations in the blood and brain) and in vitro studies to clarify the mode of action of the VOCs. Recent work in vitro has focused on quantifying the inhibitory effects of toluene, trichloroethylene (TCE) and perchloroethylene (PERC) on ion channel currents. All three VOCs inhibit current through voltage-sensitive calcium channels (VSCCs) in pheochromocytoma cells; PERC blocked calcium currents and altered the current-voltage relationship at lower concentrations than did toluene or TCE. Recombinant nicotinic acetylcholine receptors (nAChRs), expressed in Xenopus oocytes, were also inhibited by PERC and toluene in a concentration-dependent manner. PERC inhibited alpha 7 receptors more than alpha 4 beta 2 receptors in recombinant human and rat nAChRs. However, human and rat alpha 7 receptors were equally sensitive to PERC and TOL. These in vitro studies will be used to identify an appropriate neuronal receptor system to serve as an index of acute effects of VOCs in vivo. The PBTK model incorporates physiological input parameters derived from radiotelemetered heart rate data from rats performing operant tests of cognitive and motor functions. These studies should improve predictions of target organ concentrations of inhaled VOCs in subjects actively performing behavioral tests over a range of physical activity levels.

The most common environmental source of pentachlorophenol (PCP) and other chlorinated phenols are via the lumber industry as a wood preservative and as a pesticide in plant production. The US Environmental Protection Agency's (EPA) contaminant candidate list (CCL) includes a majority of these compounds as unregulated contaminants. Except for pentachlorophenol, there is a lack of human or animal data base which can be used for human health risk assessment. The specific aim of this study is to develop a rationale to use in vivo nonmammalian, in vitro mammalian and nonmammalian, micro-organism toxicity data base, structural activity, mechanistic and toxicokinetic data bases for developing a relative toxic potency ranking scheme of chlorophenols. Although the toxic potency of chlorophenols was found to increase with the number of chlorines, the potency decreases if the chlorines are attached in the ortho position of the molecules. Based on the LOAELs and mammalian in vitro data, the relative potency of chlorophenols determined to be best estimated by the ratios of log K sub(OW) to the 0.55 power. The relationship of the toxic potency derived from such an approach is largely presumptive.

These problems and limitations include: (a) unknown prevalence of hormetic dose-response curves; (b) random chance occurrence of hormesis and the shortage of data on the repeatability of hormesis; (c) unknown degree of generalizability of hormesis; (d) there are dose-response curves that are not hormetic, therefore hormesis cannot be universally generalized; (e) problems of post hoc rather than a priori hypothesis testing; (f) a possible large problem of `false positive' hormetic data sets which have not been extensively replicated; (g) the `mechanism of hormesis' is not understood at a rigorous scientific level; (h) in some cases hormesis may merely be the overall sum of many different mechanisms and many different dose-response curves - some beneficial and some toxic. For all of these reasons, hormesis should not now be used as the principal dose-response default assumption in risk assessment. At this point, it appears that hormesis is a long way away from common scientific acceptance and wide utility in biomedicine and use as the principal default assumption in a risk assessment process charged with ensuring public health protection.

This paper identifies four different levels of homology of assessment based on identity of measurement, function, and underlying neural substrate. These are discussed using detailed examples from toxicology of the visual system, with additional examples from tests of motor and cognitive function. This should provide a framework for considering both animal to human extrapolation and human to animal extrapolation, that is, how to import human experimental epidemiology findings into the lab for further work investigating mechanisms of toxicity. Designing neurobehavioral or sensory evaluations that permit easier extrapolation between human and animal models is necessary if we are to develop testing strategies that take advantage of mechanistic information at whole animal, in vitro, proteonomic, or genomic levels.

For volatile organic compounds, such as toluene and trichloroethylene (TCE), blood and brain concentrations can be estimated with physiologically based pharmacokinetic (PBPK) models. Acute changes in the function of the nervous system can be linked to the concentration of test compounds in the blood or brain at the time of neurological assessment. This set of information enables application to a number of risk assessment situations. For example, we have used this approach to recommend duration adjustments for acute exposure guideline levels (AEGLs) for TCE such that the exposure limits for each exposure duration yield identical tissue concentrations at the end of the exposure period. We have also used information on tissue concentration at the time of assessment to compare sensitivity across species, adjusting for species-specific pharmacokinetic differences. Finally this approach has enabled us to compare the relative sensitivity of different compounds on a tissue dose basis, leading to expression of acute solvent effects as ethanol-dose equivalents for purposes of estimating cost-benefit relationships of various environmental control options.

Expression of VSSCs in oocytes from Xenopus laevis is an experimental model used to study the effects of pyrethroids. A common assumption when utilizing this model is that media concentration is an accurate substitute for tissue dose. This assumption may not hold true for lipophilic chemicals. [ super(3)H]-deltamethrin (DLT) was used to test the hypothesis that media concentration is a good surrogate for tissue concentration. Accumulation of DLT (0.001-10 mu M) in non-transfected oocytes exposed for 20 min was determined using liquid scintillation counting. The time course (1.0-180 min) of tissue accumulation of DLT ([not, vert, similar]1.0 mu M (0.50 ppm) in media) was also determined. Results demonstrate that tissue dose increases as a function of time with media concentration underestimating tissue dose at long incubation times ([not, vert, similar]2.0-fold at 180 min) and overestimating tissue dose short incubation times ([not, vert, similar]8.6-fold at 5 min). Tissue dose increases as a function of media concentration, with overestimation of tissue dose ranging from 1.5-fold at 0.0005 ppm to 4.1-fold at 5.0 ppm.

We used Monte Carlo simulations to generate data representing 100 towns, each with 100 births (n=1o,ooo). Each town was assigned a mean total trihalomethane (TTHM) exposure value (mean=45, SD=28) based on a variable number of sampling locations (range 2-10). True maternal TTHM exposure was randomly assigned from a lognormal distribution using that town's true mean value. We compared the effect of a 20 mu g/1 increase in TTHM exposure on the risk of small-for-gestational age infancy using the true maternal exposure compared to various weighting measures of the town mean exposures. The exposure metrics included: (1) unweighted town mean, (2) town mean weighted by the inverse variance of the town mean, (3) town mean weighted by the inverse standard deviation of the town mean, (4) town mean weighted by 1-(standard deviation of sites per town/mean across all towns), and (5) a randomly selected value from one of the sites within the town of residence. To estimate the magnitude of misclassification bias from using the town mean concentrations, we compared the true exposure odds ratios (1.00, 1.20, 1.50, and 2.00) to the mean exposure odds ratios from the five exposure scenarios. Misclassification bias from the use of unweighted town mean exposures ranged from 19 to 39%, increasing in proportion to the size of the true effect estimates. Weighted town mean TTHM exposures were less biased than the unweighted estimates of maternal exposure, with bias ranging from o to 23%. The weighted town mean analyses showed that attenuation of the true effect of DBP exposure was diminished when town mean concentrations with large variability were downweighted. We observed a trade-off between bias and precision in the weighted exposure analyses, with the least biased effects estimates having the widest confidence intervals. Effect attenuation due to intrasystem variability was most evident in absolute and relative terms for larger odds ratios.

Two successive GAC regeneration cycles were performed involving iterative adsorption and oxidation processes: MTBE was adsorbed to the GAC, oxidized, re-adsorbed, oxidized, and finally re-adsorbed. Oxidant solutions comprised of hydrogen peroxide (H sub(2)O sub(2)) (1.7-2.0%) and FeSO sub(4) times 7H sub(2)O (3 g/L) (pH 2.5), were recirculated through the GAC column (30% bed expansion). The regeneration efficiency after two full cycles of treatment was calculated to be 91%. The cost of H sub(2)O sub(2) was $0.59/kg GAC ($0.27/lb) per regeneration cycle. There was no loss of sorptive capacity. Small reductions in carbon surface area and pore volume were measured. The lack of carbon deterioration under aggressive oxidative conditions was attributed to the oxidation of the target contaminants relative to the oxidation of carbon surfaces. The reaction byproducts from MTBE oxidation, tertiary butanol and acetone, were also degraded and did not accumulate significantly on the GAC. Excessive accumulation of Fe on the GAC and consequent interference with MTBE sorption oxidative solution.

AN - 16199412; 6449179 AB - In this paper, evidence from the current literature is presented that addresses either of two questions: 1) do EDCs in the aquatic environment have the potential to impact the reproductive health and survival of various fish species, and 2) are EDCs in the aquatic environment actually impacting the reproductive health and sustainability of indigenous populations of fish? Overall, data from laboratory experiments support the hypothesis that EDCs in the aquatic environment can impact the reproductive health of various fish species, but evidence that EDCs in the aquatic environment are actually impacting the reproductive health and sustainability of indigenous fish populations is less convincing. The scarcity of evidence linking impacts of environmental EDCs with changes in reproductive success of indigenous fish populations may reflect a critical need for a dependable method or indicator to assess reproduction of fish in situ. In addition, more studies that investigate whether fish populations routinely exposed to EDCs in situ are experiencing changes in population structure are needed. Linking endocrine disruption and reproductive impairment with an ecologically relevant impact on the sustainability of real fish populations remains, with few exceptions, an open challenge.

These types of watersheds are widespread in Montana and many other areas of the western United States. Impacts from abandoned hardrock or metal mines include loadings of sediment, metals, and other pollutants causing impairment of multiple beneficial uses and exceedances of water quality standards. The United States Environmental Protection Agency (EPA) Water Quality Analysis Simulation Program (WASP) was used to model and evaluate TMDLs for several heavy metals in Tenmile Creek, a mountain stream supplying drinking water to the City of Helena, Mont. The model was calibrated for baseflow conditions and validated using data collected by the EPA and the United States Geological Survey, and used to assess existing metals loadings and losses, including interactions between metals in water and bed sediment, uncertainty, water quality standard exceedances, TMDLs, potential source areas, and required reductions in loadings. During baseflow conditions, adits and point sources contribute significant metals loadings to Tenmile Creek. Exceedances of standards are widespread throughout the stream under both baseflow and higher flow conditions. Adsorption and precipitation onto bed sediments play a primary role in losses from the water column in some areas. Modeling results indicate that some uncertainty exists in the metal partition coefficients associated with sediment, significance of precipitation reactions, and in locations of unidentified sources and losses of metals. TMDLs and loading reductions were calculated based on variations in flow, concentrations, loadings, and standards (which vary with hardness) along the mainstem. In most cases, considerable reductions in loadings are required to achieve TMDLs and water quality standards. Reductions in loadings from point sources, mine waste near watercourses, and streambed sediment can help improve water quality, but alteration of the water supply scheme and increasing baseflow will also be needed.

Both experimental and epidemiological evidences suggest that some of the adverse health effects associated with chronic exposure to inorganic arsenic may be mediated by these methylated metabolites. If iAs methylation is an activation process, then the phenotype for inorganic arsenic methylation may determine risk associated with exposure to this metalloid. We examined inorganic arsenic methylation phenotypes and arsenic (+3 oxidation state) methyltransferase genotypes in four species: three that methylate inorganic arsenic (human (Homo sapiens), rat (Rattus norwegicus), and mouse (Mus musculus)) and one that does not methylate inorganic arsenic (chimpanzee, Pan troglodytes). The predicted protein products from arsenic (+3 oxidation state) methyltransferase are similar in size for rat (369 amino acid residues), mouse (376 residues), and human (375 residues). By comparison, a 275-nucleotide deletion beginning at nucleotide 612 in the chimpanzee gene sequence causes a frameshift that leads to a nonsense mutation for a premature stop codon after amino acid 205. The null phenotype for inorganic arsenic methylation in the chimpanzee is likely due to the deletion in the gene for arsenic (+3 oxidation state) methyltransferase that yields an inactive truncated protein. This lineage-specific loss of function caused by the deletion event must have occurred in the Pan lineage after Homo-Pan divergence about 5 million years ago.

Potassium bromate (KBrO sub(3)) is a by-product from ozonation of high-bromide surface water for production of drinking water and is a rodent carcinogen that produces thyroid, mesothelial, and renal tumors. The proposed mechanism of KBrO sub(3) renal carcinogenesis involves the formation of 8-oxoguanine (8-oxoG), a promutagenic base lesion in DNA typically removed through base excision repair (BER). In this study, male Long-Evans rats were exposed via drinking water to carcinogenic concentrations Of KBrO sub(3) (0.4 g/L), 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (0.07 g/L), chloroform (1.8 g/L), bromodichloromethane (0.7 g/L), or a mixture of all these chemicals at the same concentrations for 3 weeks. Half of one kidney was processed for microscopic examination, and the remaining kidney was frozen for isolation of genomic DNA. Levels of 8-oxoG were measured using HPLC with electrochemical detection in DNA samples incubated with formamidopyrimidine-DNA glycosylase. Aldehydic lesions (e.g. abasic sites) in DNA samples were quantitated using an aldehyde-reactive probe slot-blot assay. Treatment with KBrO sub(3) produced a measurable increase of 8-oxoG in the kidney, and this effect was greater than that produced by treatment with the DBP mixture. No other single chemical treatment caused measurable increases of 8-oxoG. The mixture effect on the amount of 8-oxoG observed in this study suggests an interaction between chemicals that reduced the generation of oxidative DNA damage. No increases in abasic sites were observed with treatment, but a decrease was apparent in the rats treated with the DBP mixture. These data are consistent with previous studies where chronic exposure to this chemical mixture in drinking water resulted in a less than additive carcinogenic response in Tsc2 mutant Long-Evans rats.

Mature and old-growth boreal forests provide a large number of products that are culturally and economically important, from wood-based lumber, pulp, and fuel wood, to numerous nonwood products. Intensive wood harvest and conservation of naturally dynamic intact forests tend to be mutually exclusive; where biodiversity is highly valued, wood harvests are limited or banned outright. The authors of this Policy Forum advise that increasing domestic forest protection without decreasing demand for wood necessitates an increase in foreign imports, which introduces a negative impact on forest biodiversity elsewhere. In some cases, exporting impact across the border may cause negative impacts to boomerang back into the country's protected forests.

AN - 67814337; 15750771 AB - Rainbow trout were exposed to a sublethal concentration of waterborne Cd (0 or 3 microg/L) or dietary Cd (0 or 500 mg/kg dry wt) for 30 days to induce acclimation, and tissue Cd and metallothionein (MT) levels were examined. The greatest Cd concentrations were observed in the kidney followed by the gills and liver of the fish exposed to Cd via water, but in the gut tissues followed by the kidney, liver, and gills for dietary-exposed fish, reflecting a variation depending on the route of Cd exposure. Some MT was found in the nonacclimated naïve fish with no experience of elevated Cd exposure, and these background MT levels were quite high in the posterior intestine (480 microg/g), cecae (257 microg/g), and liver (248 microg/g) relative to other tissues (7-50 microg/g). With exposure to both waterborne and dietary Cd, MT levels rose significantly in all observed tissues. The increases relative to the control levels of MT in naïve fish were in the order: kidney (5.4 times) > gills (4.6) > liver (1.3) for the waterborne exposure group, and in the order kidney (19.3 times) >> cecae and posterior intestine (approximately 6.5 times) > liver and stomach (approximately 5 times) > midintestine (4.3 times) > gills (2.1 times) for the dietary exposure group. At 24 hours after an acute gastrointestinal dose of Cd (276 microg/kg) infused into the stomach of dietary exposure groups, large increases of total Cd but not MT levels were found in the gut tissues of nonacclimated fish; in the Cd-acclimated fish, the posterior intestine was greatly affected with decreases in Cd (71%), Zn (33%), Cu (70%) and MT (46%) levels, suggesting an enhanced sloughing of tissue materials after infusion. Exposure to Cd did not cause any notable decrease of Zn or Cu in any tissue, except that found in the posterior intestine. However, a molar analysis indicated that although Cd levels remained less than MT binding capacity in both waterborne and dietary exposure groups, the total metal levels (Cd + Zn + Cu) greatly exceeded MT binding capacity in all tissues of Cd-exposed fish, suggesting a potential competition of Cd with other metals for binding sites on MT and non-MT proteins in the tissues.

AN - 67754960; 15839568 AB - The perchlorate anion inhibits thyroid hormone (TH) synthesis via inhibition of the sodium-iodide symporter. It is, therefore, a good model chemical to aid in the development of a bioassay to screen chemicals for affects on thyroid function. Xenopus laevis larvae were exposed to sodium perchlorate during metamorphosis, a period of TH-dependent development, in two experiments. In the first experiment, stage 51 and 54 larvae were exposed for 14 d to 16, 63, 250, 1,000, and 4,000 microg perchlorate/ L. In the second experiment, stage 51 larvae were exposed throughout metamorphosis to 8, 16, 32, 63, and 125 microg perchlorate/L. Metamorphic development and thyroid histology were the primary endpoints examined. Metamorphosis was retarded significantly in the first study at concentrations of 250 microg/L and higher, but histological effects were observed at 16 microg/L. In the second study, metamorphosis was delayed by 125 microg/L and thyroid size was increased significantly at 63 microg/L. These studies demonstrate that inhibition of metamorphosis readily can be detected using an abbreviated protocol. However, thyroid gland effects occur at concentrations below those required to elicit developmental delay, demonstrating the sensitivity of this endpoint and suggesting that thyroidal compensation is sufficient to promote normal development until perchlorate reaches critical concentrations.

VII. Degeneration of dopaminergic neurons in Apo E-/- mice. AN - 67703328; 15804941 AB - This study reports that subchronic exposure of Tuxedo, NY concentrated ambient particulates (CAPs) produces neuropathological damage in the brains of Apo E-deficient mice (Apo E-/-). These genetically modified mice are characterized by elevated levels of oxidative stress (OS) in the brain. Microscopic examination of coronal sections of the brain, immunocytochemically stained for dopamineric neurons, indicated that neurons from the substantia nigral nucleus compacta were significantly reduced by 29% in CAPs-exposed Apo E-/- mice relative to air-exposed Apo E-/- controls. In addition, statistically significant increases (p < .05) in immunocytochemically stained astrocytes were noted. The dopaminergic neurons of the nucleus compact are specifically targeted in Parkinson's disease. The present study expands the systems affected by particulate matter to include the brain, and supports an environmental role for the development of neurodegeneration in OS-susceptible individuals.

AN - 67512458; 15655806 AB - A risk assessment of the triazine herbicide atrazine has been conducted by first analyzing the toxicity database and subsequently estimating exposure. Margins of safety (MOS) were then calculated. Toxicity was assessed in animal studies and exposure was estimated from occupational and dietary sources. In acute toxicity studies, atrazine caused developmental toxicity in the rabbit [no observed effect level (NOEL) 5 mg kg(-1) day(-1)] and cardiotoxicity in a dog chronic study (NOEL 0.5 mg kg(-1) day(-1)); cancer (mammary glands) resulted from lifetime exposure. The mammary tumors, which occurred specifically in female Sprague-Dawley rats, were malignant, increased in a dose-dependent manner and were also observed with other, related triazines. Evidence for a genotoxic basis for these tumors was either equivocal or negative. Triazines have been shown to be clastogenic in Chinese hamster ovary cells, in vitro, but without showing a convincing dose/response relationship. Atrazine can be converted into genotoxic N-nitrosoatrazine in the environment or the digestive system, suggesting that N-nitrosamines derived from triazines could be oncogenic. However, it was concluded that N-nitrosotriazines are unlikely to play a significant role in triazine-induced rat mammary gland tumors. An endocrine basis for the mammary tumors, involving premature aging of the female SD rat reproductive system, has been proposed. A suppression of the luteinizing hormone surge during the estrus cycle by atrazine leads to the maintenance of elevated blood levels of 17beta-estradiol (E2) and prolactin. The mechanism for tumor development may include one or more of the following: the induction of aromatase (CYP19) and/or other P450 oxygenases, an antagonist action at the estrogen feedback receptor in the hypothalamus, an agonist action at the mammary gland estrogen receptor or an effect on adrenergic neurons in the hypothalamic-pituitary pathway. None of these has been excluded as a target because there has been a lack of a rigorous attempt to address the mechanism of action for mammary tumors at the molecular level. The potential occupational exposure to atrazine was assessed during mixing, loading and application. Absorbed daily dosage values were 1.8-6.1 microg kg(-1) day(-1). The MOS values (animal NOEL/human exposure) for short-term (acute) exposure were 820-2800. Longer-term occupational exposure and risk were also calculated. Detectable crop residues are generally absent at harvest. Theoretical calculations of acute dietary exposure used tolerance levels, along with secondary residues, and water, for which there is a maximum contamination level; atrazine plus the three main chlorotriazine metabolites were combined. MOS values were above 2000 for all population subgroups. Dietary exposure to atrazine is therefore extremely unlikely to result in human health hazard. Recent publications have reported a possible feminization of frogs, measured in laboratory and field studies. This is assumed to be due to the induction of aromatase, but no measurements of enzyme activity have been reported. In field studies, the water bodies with the greatest numbers of deformed frogs sometimes had the lowest concentrations of atrazine. Other studies have also cast doubt on the feminization theory, except perhaps at very high levels of atrazine. Epidemiology studies have investigated the possibility that atrazine may result in adverse effects in humans. Although some studies have claimed that atrazine exposure results in an elevated risk of prostate cancer, the published literature is inconclusive with respect to cancer incidence.

These groundwaters are commonly found a long distance from their ultimate source of arsenic, where chemical weathering of As-bearing minerals occurs. We propose a "GBH-As" model that ties together all of the important tectonic, biologic, and hydrologic processes that cause natural As release in groundwater in Holocene terrestrial deposits. Processes highlighted by the "GBH-As" model can explain the movement of arsenic from lithosphere to hydrosphere. However, we propose a factor that has increased dissolved As concentrations in Holocene aquifers to levels where human health is threatened: mechanical weathering associated with Pleistocene glaciation. Our model invokes erosion of mountain belts aided by glaciers, transport of arsenic by surface waters, adsorption of As by stream sediments, and deposition of stream sediments and organic matter in alluvial deposits. Subsequently, Fe(III)-reducing bacteria present in alluvial aquifers cause the release of sorbed As to groundwater under moderately reducing conditions.

Asbestiform amphibole fibers from the Libby area, are predominately comprised of actinolite, tremolite, winchite, and richterite mineral forms of amphibole (Libby Amphibole). About half of the airborne fiber exposures occurring in the Libby area are to asbestiform amphibole fibers that are not commonly included in exposure assessments under the current asbestos analytical protocols and regulatory definitions. The asbestos-related occupational illnesses associated with exposures to Libby Amphibole among former vermiculite miners are well established in the medical literature, with significantly increased rates of asbestosis, lung cancer, and mesothelioma. Recent mortality studies conducted by federal health officials have also documented markedly elevated rates of asbestosis (40-80 times that of the US population), lung cancers, and mesothelioma in the community. Results of large-scale medical testing conducted on over 7300 individuals who lived or worked in the community prior to 1990, revealed the prevalence of asbestos-related lung abnormalities in about 18% of all participants. The prevalence of such abnormalities increased with increasing number of exposure pathways, ranging from 6.7% for those who reported no apparent exposures to 34.6% for those who reported 12 or more pathways. Pathways of concern include both occupational and non-occupation exposures, many of which still exist in the community today, despite the closure of the mine in 1990. Various activities involving remediation of contaminated soils, attic insulation, and indoor dust have been completed at over 350 properties to date, and will continue for years to come.

Until recently, most deposits were located in remote and sparsely populated areas. That situation is changing, as population growth in the greater Sacramento area pushes farther east into the Sierra foothills. Housing subdivisions, commercial development, and the attendant large-scale earth movement required for building have raised concerns regarding potential human exposure to disturbed asbestos. In 2003, amphibole and chrysotile asbestos was discovered in the surface soil of partially completed soccer fields at a high school in El Dorado Hills, California. Subsequent limited air sampling demonstrated that disturbance of soil with relatively low levels of asbestos could result in significant exposures in the breathing zone. The information prompted remediation of the campus to cap soils containing amphibole and chrysotile asbestos fibers. Concern that the potential exposure was not confined to the boundaries of the high school resulted in submission of a formal CERCLA (commonly known as "Superfund") petition requesting that EPA conduct an assessment of other public areas in El Dorado Hills. In response to the petition, EPA Region 9 conducted eleven days of asbestos soil and air sampling in El Dorado Hills in October 2004. EPA contractors simulated the activities of adults and children playing baseball, soccer, and basketball, running and biking, using a play structure, and gardening at three schools, a public park, and a popular nature trail and measured asbestos fibers in the breathing zone. The contractors wore personal air samplers, set at 3' in height for the child scenarios and 5' for the adult scenarios, and filters were analyzed by the ISO 10312 TEM method for detection and speciation of asbestos fibers. In addition, reference air samples were collected in El Dorado Hills outside the areas influenced by the activity-based monitoring for comparison purposes. The soil samples were analyzed by PLM and TEM. This presentation will discuss the sampling design and execution as well as the results of the investigation.

This study identifies a typically unrecognized nitrate contamination risk of enhanced recharge of surface water through groundwater management activities. Augmented recharge can mobilize nitrate sources that would not affect the regional aquifer under natural, low recharge-rate conditions. An investigation of a nitrate contaminated groundwater basin in Livermore, California, demonstrates that nitrate isotope data are effective in determining contaminant sources, and that other isotopic tracers such as oxygen isotopes and tritium-helium ages give insight into the routes and timing of nitrate inputs to the flow system. Low nitrate reclaimed wastewater predominates in the northwest, while two flowpaths with distinct nitrate sources originate in the southeast. Along the eastern flowpath delta (super 15) N values greater than 10 per mil indicate that animal waste is the primary source. Diminishing concentrations over time suggest that nitrate contamination results from historical land use practices. The other flowpath begins in an area where rapid recharge, primarily of low-nitrate imported water (identified by stable isotopes of water and a tritium-helium residence time of less than 1 year), mobilizes a significant local nitrate source, bringing groundwater concentrations up to 53 mg/L. In this area, artificial recharge of State Project water via local arroyos induces a flux of the contaminant to the regional aquifer. The low delta (super 15) N (3.1 per mil) value in this location implicates synthetic fertilizer, although nitrification in the root zone of natural vegetation is another likely contributor. Geochemical modeling supports the hypothesis of separate sources, one including organic carbon, as from animal waste, and one not. In addition to these anthropogenic sources, natural nitrate background levels between 15 and 20 mg/L are found in deep wells with residence times greater than 50 years. This work was performed under the auspices of the U.S. Department of Energy by the University of California, Lawrence Livermore National Laboratory under Contract W-7405-Eng-48.

Historically, the area has been extensively mined for chrysotile asbestos, mercury, chromite, and other commodities associated with serpentinite. The Clear Creek Management Area (CCMA), located on and around this ore body, is a popular 50,000 acre recreational area managed by the Bureau of Land Management (BLM). It provides 400-600 miles of unpaved vehicle routes and almost 3,000 acres of barren hill climbs for off-highway vehicle (OHV) users, as well as other recreational opportunities such as hiking, camping, hunting, and rock collecting. Within the CCMA is a 30,000 acre area designated as a "Hazardous Asbestos Area", due to elevated levels of naturally occurring (unprocessed) asbestos. The United States Environmental Protection Agency (U.S. EPA) and the BLM have long been concerned about potential health hazards associated with the generation and inhalation of airborne asbestos fibers by users of the area, particularly those operating OHV's on unpaved routes. U.S. EPA, in collaboration with BLM and the California EPA (DTSC), is in the process of gathering information to estimate asbestos exposure, as a basis for determining appropriate mitigation measures. Air samples are being collected during both dry and wet seasons by individuals wearing personal monitors, while engaged in typical recreational activities. These activities include motorcycle riding, all terrain vehicle riding, sport utility vehicle driving, hiking, camping, and washing and vacuuming dusty vehicles. The exposure of child users is being specifically evaluated, by positioning monitors to mimic a child's breathing zone. Soil moisture and asbestos concentration along the user's route of travel are also being measured, to test whether these parameters correlate with airborne asbestos concentrations.

Watershed planning designed to strategically restore wetlands has the potential to provide dramatic benefits by restoring ecosystem-level processes (functions) that maintain water resource integrity. We developed a GIS-based model to predict the suitability for wetland restoration for all locations in the Cuyahoga River watershed (2107km2), in northeastern Ohio (U.S.A.). The model offers a useful tool to focus and set goals for wetland restoration efforts in a spatially explicit way. A two-phase approach was used: the first is to develop criteria, or environmental indicators, to identify the total population of sites suitable for wetland restoration. Locations are identified where restoration has a high likelihood of success and will be sustainable over the long term. Criteria used include hydric soils, land use, topography, stream order, and a saturation index based on slope and flow accumulation in each grid cell in the model. The second phase 'filters'the total population of available sites in order to prioritize them according to their potential to contribute to water resource integrity once restored. We generated three versions of the suitability model depicting restoration potential. All versions rely on the same criteria but vary in how the factors were weighted or the hydrology criterion was calculated.

The makeup of aquatic biological assemblages (e.g., fish, macroinvertebrates, algae, riparian birds, etc.) varies dramatically over the landscape, as do the environmental stresses that affect the condition of those assemblages. Ecoregions delineate areas where similar assemblages are likely to occur and, therefore, where similar expectations can be established. For this reason, ecological regions have proven to be an important tool for use in the process of ecological assessment. This article describes four examples of the use of ecological regions in important aspects of environmental monitoring and assessment: (1) design of monitoring networks; (2) estimating expected conditions (criteria development); (3) reporting of results; (4) setting priorities for future monitoring and restoration. By delineating geographic areas with similar characteristics, ecological regions provide a framework for developing relevant indicators, setting expectations through the use of regional reference sites, establishing ecoregion-specific criteria and/or standards, presenting results, focusing models based on relationships between landscape and surface water metrics, and setting regional priorities for management and restoration. The Environmental Protection Agency and many state environmental departments currently use ecoregions to aid the development of environmental criteria, to illustrate current environmental condition, and to guide efforts to maintain and restore physical, chemical and biological integrity in lakes, streams, and rivers.

To develop a framework for general practice management made up of quality indicators shared by six European countries. Methods. Two-round postal Delphi questionnaire in the setting of general practice in Belgium, France, Germany, The Netherlands, Switzerland and the United Kingdom. Six national expert panels, each consisting of 10 members, primarily primary care practitioners and experts in the field of quality in primary care participated in the study. The main outcome measures were: (a) a European framework with indicators for the organization of primary care; and (b) ratings of the face validity of the usefulness of the indicators by expert panels in six countries. Results. Agreement was reached about a definition of practice management across five domains (infrastructure, staff, information, finance, and quality and safety), and a common set of indicators for the organization of general practice. The panellist response rate was 95%. Sixty-two indicators (37%) were rated face valid by all six panels. Examples include out of hours service, accessiblility, the content of doctors' bags and staff involvement in quality improvement. No indicators were rated invalid by all six panels. Conclusions. It proved to be possible to develop a European set of indicators for assessing the quality of practice management, despite the differences in health care systems and cultures in the six different countries. These indicators will now be used in a quality assessment procedure of practice management in nine European countries. While organizational indicators are part of the new GMS contract in the UK, this research shows that many practice management issues within primary care are also of relevance in other European countries.

We examined plant assemblages, and 31 of the most common species comprising them, from emergent wetlands in an urbanizing area of the Pacific Northwest, USA, in relation to in situ, fine-scale hydrology. Percent cover by plant species was estimated in 2208 1-m super(2) plots across 43 sites, with water depth at time of vegetation sampling measured in 432 plots. Three years of bi-weekly hydrologic data from each of the 43 sites were used to estimate mean surface water level and mean absolute difference (MAD) in surface water level for every plot. Nine assemblages of plant species that co-occur in the field were identified using TWINSPAN. The assemblage richest in native species occurred under intermediate hydrologic conditions and was bracketed by pasture grass dominated assemblages at drier conditions with low water level variability, and Phalaris arundinacea L. assemblages with higher mean water levels and variability. Results suggest minor changes in average water levels ( similar to 10 cm) or in variability ( plus or minus 2 cm in MAD) could promote a shift from assemblages dominated by natives to those dominated by invasive or alien taxa. Canonical correspondence analysis segregated the species into four groups related to hydrologic gradients. Each species response group was typified by taxa with similar optima for a given environmental variable, with each group related to a characteristic suite of hydrologic conditions. The most common species (P. arundinacea, Juncus effusus L., and Typha latifolia L.), each representing a different response group, exhibited unique responses in occurrence/abundance in relation to water level variability, but were abundant over a wide range of water depth. The realized niches of other species in each response group were more restricted, with peaks in cover confined to narrower ranges of water depth and variability.

Due to its contribution to abnormally high stream flows and its role as a carrier of pollutants that degrade water quality, excess stormwater runoff has negative impacts on both terrestrial and aquatic ecosystems. In response to the increased magnitude and frequency of stormwater runoff events, municipalities and local governments seek cost-effective strategies to manage the risks associated with these stormwater flows. The goal of a proposed interdisciplinary approach involves providing incentives for the construction of small-scale best management practices throughout a small urban watershed, leading to a cost-effective means to control stormwater runoff, and partially restoring a more natural hydrologic regime to a watershed area. Market mechanisms and other incentives have been suggested as plausible approaches to the reduction of stormwater runoff. Development and implementation of market mechanisms and incentives to reduce stormwater runoff, however, involves interdisciplinary considerations and issues. This paper develops an interdisciplinary view of the stormwater runoff issue, beginning with a brief description of stormwater runoff management from a hydrologic perspective. We then present a background on types of market instruments and their related incentives as possible approaches to reducing the risks associated with both the magnitude and frequency of recurrence for excess stormwater runoff flows. This is followed by an analysis of how the federal Clean Water Act and state water laws have dealt with stormwater issues. These perspectives and methods are synthesized to develop several stormwater management scenarios that include stormwater user fees, stormwater runoff charges, allowance markets, and voluntary offset programs. Each of these programs would likely incorporate stormwater best management practices at the watershed level, yet in different ways, and we discuss the opportunities and limitations borne out of our analysis of the legal, economic, and hydrologic considerations.

Designed primarily for regulatory applications, the model can estimate both the individual dose and risk for a critical population group and the collective health effects to a general population. This paper presents the theoretical background of PRESTO's dynamic infiltration component. The simulation of infiltration involves solving the dynamic equations that govern the transport of liquid and vapor phases of water in the overland flow, subsurface flow, and atmospheric diffusion systems. The basic space-dependent partial differential equations that describe these processes are transformed into space-independent ordinary differential equations; this entails subdividing the soil moisture content into three components: gravity, pellicular, and hygroscopic waters. Modeling validation, as assessed at the Barnwell, S.C. site, indicates that the simulation results agree well with field studies conducted by the USGS and by the US NRC. Tests and validation runs have demonstrated that: (1) the calculation results can simulate infiltration through a saturated/unsaturated subsurface soil layer, (2) instabilities of numerical calculation do not occur, and (3) the run time for model execution is reasonably short. Because of lack of reliable field data, the model can only be verified and not fully validated.

Distinguishing between these behavioral and environmental causes of pattern is of general interest to spatial ecologists and continues to be a key unresolved issue. Despite the importance of this problem, systematic approaches for resolving the underlying mechanisms are not well developed. We demonstrate here the value of a three-tiered systematic approach involving descriptive spatial sampling, individual-based observation and diffusion modeling, and manipulative field experiments. We used this approach to test social- vs. habitat-driven hypotheses explaining spatial aggregation in the collembolan Orchesella hexfasciata. Our results show that aggregation is a gregarious behavior triggered by seasonal increases in soil moisture. Initial field observations suggested that aggregation was habitat driven and associated with soil moisture, but individual-based observations and modeling revealed that moisture was only a triggering mechanism for socially driven aggregation. This was corroborated in field experiments by testing hypotheses that were motivated by the individual-based analyses. Thus, the three-tiered approach led to a more complete understanding of aggregation than would any single technique.

The induction of CYP1A2 activity has been used as a noninvasive biomarker for human exposure to dioxins; while there is a consistent relationship between exposure and hepatic CYP1A2 induction in rodents, this relationship has only been observed in some of the highest exposed human populations. This may be explained by inhibition of CYP1A2 activity by dioxins as some rodent studies demonstrate that rodent CYP1A2 activity can in fact be inhibited by dioxins in vitro. CYP1A2 activity was examined using a series of dioxins to inhibit human and rat CYP1A2 activity in species-specific CYP1A2 SUPERSOMES using three common CYP1A2 substrates. Methoxyresorufin was a more efficient substrate than acetanalide or caffeine in this in vitro system. Rat and human CYP1A2 enzymatic activity is inhibited by TCDD, PCDD, TCDF, 4- PeCDF, and PCBs 126, 169, 105, 118, and 156 in a concentration-dependent manner. These data demonstrate that the in vitro metabolism of prototype substrates is similar between the rat and human CYP1A2 SUPERSOME preparations and that dioxins inhibit CYP1A2 activity in both species. Because of the potential for inhibition of CYP1A2 activity by TCDD and other dioxins, studies examining CYP1A2 induction in dioxin-exposed populations using these substrates should be viewed cautiously.

These methods may often be time-consuming and inaccurate, necessitating the development of identification protocols that are rapid, sensitive, and precise. The polymerase chain reaction (PCR) has shown great promise in its ability to identify and quantify individual organisms from a mixed culture environment; however, the cost effectiveness of single organism PCR reactions is quickly becoming an issue. Our laboratory has developed a simple method to identify multiple fungal species, Stachybotrys chartarum, Aspergillus versicolor, Penicillium purpurogenum, and Cladosporium spp. by performing multiplex PCR and distinguishing the different reaction products by their mobility during agarose gel electrophoresis. The amplified genes include the beta -Tubulin gene from A. versicolor, the Tri5 gene from S. chartarum, and ribosomal sequences from both P. purpurogenum and Cladosporium spp. This method was found to be both rapid and easy to perform, while maintaining high sensitivity and specificity for characterizing isolates, even from a mixed culture.

Penicillium chrysogenum, a common indoor mold, is known to have several allergens and can induce allergic responses in a mouse model of allergic penicilliosis. Our hypothesis is that soluble components of P. chrysogenum (PCE) can dose-dependently induce responses typical of allergic asthma in BALB/c mice. Mice were exposed to 10, 20, 50, or 70 mu g of PCE by involuntary aspiration four times over a 4-week period. Serum and bronchoalveolar lavage fluid (BALF) were collected before (day 0), and at days 1 and 3 following the final exposure. PCE-exposed mice demonstrated dose-dependent increases in: BALF total cell numbers including eosinophil, serum and BALF total IgE levels, BALF IL-5 levels, and increased severity of histopathologic lesions. A single exposure to the highest dose of PCE resulted in edema and cellular damage but not immune responses. Four exposures to Metarhizium anisopliae crude antigen (10 mu g, positive control) resulted in equivalent or greater allergic asthma- like responses than those demonstrated by multiple exposures to 50 or 70 mu g of PCE. Multiple exposures to 70 mu g of PCE showed increased allergen- triggered immediate respiratory responses as well as non-specific airway hyperresponsiveness to methacholine as assessed by barometric whole-body plethysmography. Taken together, repeated pulmonary challenge with P. chrysogenum extract induced dose-dependent allergic asthma-like responses in mice.

However, both computational costs and data requirements increase significantly with increasing grid resolution. Therefore, it is important to examine, for any given application, whether the expected benefit of increased grid resolution justifies the extra costs. In this study, we examine temperature and ozone observations and model predictions for three high ozone episodes that occurred over the northeastern United States during the summer of 1995. In the first set of simulations, the meteorological model RAMS4a was run with three two-way nested grids of 108/36/12 km grid spacing covering the United States and the photochemical model UAM-V was run with two grids of 36/12 km grid spacing covering the eastern United States. In the second set of simulations, RAMS4a was run with four two-way nested grids of 108/36/12/4 km grid spacing and UAM-V was run with three grids of 36/12/4 km grid spacing with the finest resolution covering the northeastern United States. Our analysis focuses on the comparison of model predictions for the finest grid domain of the simulations, namely, the region overlapping the 12 km and 4 km domains. A comparison of 12 km versus 4 km fields shows that the increased grid resolution leads to finer texture in the model predictions; however, comparisons of model predictions with observations do not reveal the expected improvement in the predictions. While high-resolution modeling has scientific merit and potential uses, the currently available monitoring networks, in conjunction with the scarceness of highly resolved spatial input data and the limitations of model formulation, do not allow confirmation of the expected superiority of the high-resolution model predictions.

In our studies of fine- grained estuarine seabeds, we observed that E sub(h) values measured in intact sediment cores were influenced by different electrode insertion techniques. Sediment E sub(h) measurements generated via lateral insertion of platinum electrodes through silicone-filled ports in acrylic cores were systematically more positive (on the order of 10-100 mV) than profiles generated via vertical insertion of platinum electrodes downward through the sediment-water interface of the same cores. A review of the literature indicated that while researchers routinely use both insertion techniques to measure E sub(h), no discrepancy in output has previously been reported. We discuss the results of three experiments conducted to determine if the discrepancy in output was caused by electrode poisoning by sulfides during the stepwise vertical insertion technique, or was caused by contact of the electrode with the silicone plug during the lateral insertion technique. We conclude that contact between the platinum surface of the electrode and the silicone plug biases the E sub(h) measurements, resulting in erroneously positive E sub(h) values. Insertion of electrodes into sediment through silicone plugs produced E sub(h) values that were an average of 105.6 mV ( plus or minus 10.4 SE) more positive than values generated upon electrode insertion directly into sediment. Thus, we recommend against using an insertion technique where the platinum electrode remains in contact with the silicone plug, as this method results in misclassification of sediment redox state and estimated depth of the redoxcline.

Behavioral effects of acute toluene exposure could be subjected to cost-benefit analysis if the effects of toluene were quantitatively compared to those of ethanol ingestion, which has been monetized for applied contexts. Behavioral effects of toluene and ethanol were quantified by meta-analysis of studies from the peer-reviewed literature describing their effects on choice reaction time (reaction time in a test requiring a subject to choose among two or more alternatives before responding). The internal doses of these compounds were estimated by a general physiological and toxicokinetic (GPAT) simulation from exposure parameters provided in the reports. The reported effects were converted to a common metric (proportion of baseline) and related to the estimated internal doses of toluene and ethanol, from which dose-effect equations were fitted. The estimated effect of toluene was compared to the estimated effect of ethanol on the same dependent variable by deriving a dose-equivalence equation (DEE) to express the dose of toluene as an equivalent dose of ethanol on the basis of equal effect magnitude. A nomogram was constructed by GPAT simulation to relate the environmental exposure concentration of toluene to the equivalent effect magnitude of a range of ethanol internal doses. Behavioral effects and their evaluation are determined by internal doses, which in turn are determined by a variety of variables. In addition to concentration and duration of exposure, which determine internal dose by pharmacokinetic processes, the activity level of exposed persons is a major factor. This analysis provides a continuous function of the consequences of toluene exposure expressed as ethanol-equivalent doses within confidence limits. The resulting function has the potential to estimate the monetary values of behavioral deficits caused by a range of exposures to toluene from existing monetized information on ethanol.

We conducted a cross-sectional study of 480 Chinese and 494 white women, aged 40-55 years, in Northern California. Levels of exposure to organic solvents (none, low, medium, or high) were assigned to each current job using a job-exposure matrix. A lower proportion of women with low occupational organic solvent exposure reported hot flashes or night sweats than working women with no solvent exposure (adjusted prevalence odds ratio [APOR] = 0.48, 95% confidence interval [CI] = 0.19-1.21). A greater proportion of women with high solvent exposure reported forgetfulness than women with no exposure (APOR = 2.51, 95% CI = 1.12-5.63). Some symptom reporting in midlife women was related to their occupational organic solvent exposure.

In particular, we consider individuals who have duty-based ethical attitudes that lead to lexicographic preferences for environmental quality. We show that individuals with duty-based ethical attitudes have recreation demand functions that are 'kinked, ' exhibiting perfectly inelastic behavior over some range of income. However, the kinks cannot be identified from typical cross-sectional data, and to the extent that observed recreation demand for these individuals differs from those with neoclassical preferences, such differences could be captured empirically through a proxy variable that measures ethical attitudes. A more fundamental issue is that changes in welfare for duty-based individuals cannot be determined from their estimated demand function: while an exogenous rise in environmental quality is likely to increase the demand for recreation by these individuals, additional recreation is not the reason for an improvement in well-being. An empirical model to identify the effect of ethical attitudes on recreation is illustrated using survey data on stated preferences for visits to urban parks.

Typically, this requires the use of uncertain data and vaguely defined decision criteria. I developed a decision support system to address these uncertainty issues and assist in evaluating conservation opportunities for the endangered California tiger salamander (Ambystoma californiense) in Santa Barbara, California. Functionally defined planning units were used to aggregate data on land suitability, land cover change, salamander presence, and movement risk along potential linkages between breeding ponds. I used a fuzzy-logic-based inference engine to evaluate the planning units and rank the relative suitability of interpond linkages for conservation action. The sensitivity of the rankings was considered with respect to uncertainty in salamander occurrence data and the relationship between land-cover-change threats and site suitability. All linkages were substantially degraded, but five areas were consistently identified with high relative suitability for conservation action despite differences in assumptions and uncertainty in biological data. The combination of functionally defined planning units and a fuzzy-logic-based decision support system provides a general framework for considering the suitability of sites for conservation action.Original Abstract: Las organizaciones de conservacion y las agencias publicas estan interesadas en identificar y priorizar areas para acciones de conservacion, a menudo adquisiciones o convenios. Tipicamente, esto requiere el uso de datos inciertos y criterios de decision vagamente definidos. Desarrolle un sistema de apoyo de decisiones para abordar estos temas inciertos y ayudar en la evaluacion de oportunidades de conservacion de la salamandra Ambystoma californiense en Santa Barbara, California. Se utilizaron unidades de planificacion definidas funcionalmente para agregar datos sobre la aptitud del suelo, cambios en la cobertura de suelo, presencia de salamandras y riesgo de movimiento a lo largo de potenciales conexiones entre las charcas de reproduccion. Utilice un procesador de inferencia basado en logica difusa para evaluar las unidades de planificacion y clasificar la aptitud relativa de las conexiones intercharca para acciones de conservacion. La sensibilidad de la clasificacion fue considerada respecto a la incertidumbre en los datos de ocurrencia de salamandras y la relacion entre cambio en la cobertura de suelo y aptitud del sitio. Todas las conexiones estaban sustancialmente degradadas, pero cinco areas fueron consistentemente identificadas con alta aptitud relativa para acciones de conservacion, no obstante diferencias en suposiciones e incertidumbre en los datos biologicos. La combinacion de unidades de planificacion definidas funcionalmente y un sistema de apoyo de decisiones basado en logica difusa proporciona un marco general para considerar la aptitud de sitios para acciones de conservacion.

AN - 67723361; 15819228 AB - A study of personal, indoor, and outdoor exposure to PM2.5 and associated elements has been carried out for 37 residents of the Research Triangle Park area in North Carolina. Participants were selected from persons expected to be at elevated risk from exposure to particles, and included 29 persons with hypertension and 8 cardiac patients with implanted defibrillators. Participants were monitored for 7 consecutive days in each of four seasons. One goal of the study was to estimate the contribution of outdoor PM2.5 to indoor concentrations. This depends on the infiltration factor Finf, the fraction of outdoor PM2.5 remaining airborne after penetrating indoors. After confirming with our measurements the findings of previous studies that sulfur has few indoor sources, we estimated an average Finf for each house based on indoor/outdoor sulfur ratios. These estimates ranged from 0.26 to 0.87, with a median value of 0.55. Since these estimates apply only to particles of size similar to that of sulfur particles (0.06-0.5 microm diameter), and since larger particles (0.5-2.5 microm) have lower penetration rates and higher deposition rates, these estimates are likely to be higher than the true infiltration factors for PM2.5 as a whole. In summer when air conditioners were in use, the sulfur-based infiltration factor was at its lowest (averaging 0.50) for most homes, whereas the average Finf for the other three seasons was 0.62-0.63. Using the daily estimated infiltration factor for each house, we calculated the contribution of outdoor PM2.5 to indoor air concentrations. The indoor-generated contributions to indoor PM2.5 had a wider range (0-33 microg/m3) than the outdoor contributions (5-22 microg/m3). However, outdoor contributions exceeded the indoor-generated contributions in 27 of 36 homes. A second goal of the study was to determine the contribution of outdoor particles to personal exposure. This is determined by the "outdoor exposure factor" Fpex, the fraction of outdoor PM2.5 contributing to personal exposure. As with Finf, we estimated Fpex by the personal/outdoor sulfur ratios. The estimates ranged from 0.33 to 0.77 with a median value of 0.53. Outdoor air particles were less important for personal exposures than for indoor concentrations, with the median outdoor contribution to personal exposure just 49%. We regressed the outdoor contributions to personal exposures on measured outdoor PM2.5 at the central site. The regressions had R2 values ranging from 0.19 to 0.88 (median = 0.73). These values provide an indication of the extent of misclassification error in epidemiological estimates of the effect of outdoor particles on health.

Accordingly, a proper monitoring requires high-temporal resolution sampling during flow events. We report on a comparative study on the P export dynamics from two grassland catchments in Switzerland, where concentrations of dissolved reactive Phosphorus (DRP) have been monitored at a high temporal resolution for periods of 1.2 and 5y, respectively. The data set is complemented by measurements on total P (TP), total dissolved P (TDP) and particulate P (PP) obtained from routine sampling ongoing since 1984 in both catchments. In one area, the high-temporal resolution monitoring revealed a pattern of the P export dynamic as expected from other studies. During flow events DRP concentrations usually increased significantly exceeding 1000 mg DRP m (super -3) during peak flow, while the values remained low between 20 and 100 mg DRPm (super -3) at base flow. This pattern was partially confirmed in the second catchment. The expected pattern was observed in 1998 and 1999 but was partially replaced by a new one for the following years. In the growing season, DRP only weakly increased with flow rate or remained almost constant. During flow events values larger than 300-400 mg DRP m (super -3) were rare. In contrast to these relatively low peak flow concentrations, high values (200-300 mg m (super -3) ) were recorded at base flow during the years 2000-2002. During the same period, DRP concentrations exhibited strong daily oscillations. Independent sampling and analytical control measurements verify the findings. Point sources like leaks from manure tanks could be ruled out based on the ammonia measurements. We suggest that biogeochemical processes within the brook are responsible for this change in the P export dynamics. Despite these changes in the pattern of the P export dynamic and ecological measures implemented on the farms no significant effect on the annual P loads could be observed during the last 10 years.

An integrated, efficient and cost-effective process is needed to acquire and assess the data needed to meet both these mandates. A subset of presentations at the 2002 Environmental Monitoring and Assessment Program (EMAP) Symposium provided information on how probability data, tools and methods could be used by states and other entities to aid in development of their overall assessment of condition and list of impaired waters. Discussion identified some of the technical and institutional problems that hinder the use of EMAP methods and data in the analysis to identify impaired waters as well as development needs to overcome these problems.

For large-scale observational studies, sites should be selected across gradients of anthropogenic stress, but such gradients are often unknown for a population of sites prior to site selection. Stress data available from public sources can be used in a geographic information system (GIS) to partially characterize environmental conditions for large geographic areas without visiting the sites. We divided the U.S. Great Lakes coastal region into 762 units consisting of a shoreline reach and drainage-shed and then summarized over 200 environmental variables in seven categories for the units using a GIS. Redundancy within the categories of environmental variables was reduced using principal components analysis. Environmental strata were generated from cluster analysis using principal component scores as input. To protect against site selection bias, sites were selected in random order from clusters. The site selection process allowed us to exclude sites that were inaccessible and was shown to successfully distribute sites across the range of environmental variation in our GIS data.

In this study, we compared six macroinvertebrate field sampling methods for nonwadeable streams adapted from those used by three major programs: the U.S. Environmental Protection Agency's Environmental Monitoring and Assessment Program-Surface Waters, the U.S. Geological Survey's National Water Quality Assessment Program, and the Ohio Environmental Protection Agency, Division of Surface Water Biocriteria Program. We performed all six methods at 60 sites across four rivers and measured water chemistry and physical habitat at each site to assess abiotic conditon. Sites were divided into two groups: those influenced by navigational lock and dam structures (restricted flow, or RF) and those free-flowing or with lowhead dams (run-of-the-river, or ROR). Metrics based on passive Hester-Dendy artificial substrate samplers differed greatly from active sampling methods (i.e., using nets) but represented abiotic conditions well in both ROR and RF sites. Although metric values were similar across certain sampling methods, the metrics significantly correlated with abiotic variables varied among methods and between ROR and RF sites. These results emphasize that methods are not interchangeable, and the ability to detect certain stressors depends on sampling method.

In the United States, ecological monitoring and assessment of GREs has lagged behind streams and estuaries, and the management of GREs is hampered by the lack of unbiased data at appropriate spatial scales. Properties of GREs that make them challenging to monitor and assess include difficult sample logistics and high habitat diversity. The U.S. Environmental Protection Agency's Environmental Monitoring and Assessment Program (EMAP) has developed a comprehensive, regional-scale, survey-based monitoring approach to assessment of streams and estuaries, but has not yet conducted research on applying these tools to GRE monitoring. In this paper we present an overview of an EMAP research project on the Upper Missouri River (UMR). We summarize the assessment objectives for the study, the design for selecting sample locations, the indicators measured at these sites and the tools used to analyze data. We present an example of the type of statements that can be made with EMAP monitoring data. With modification, the set of methodologies developed by EMAP may be well suited for assessment of GREs in general.

Participants at a symposium sponsored by the U.S. Environmental Protection Agency (USEPA) and the Council of State Governments concluded that useful and efficient assessments of great river ecosystems require thoughtful alignment of sampling designs, spatial and temporal scales, indicators, management needs, and ecosystem characteristics. Site-specific physical, chemical, and biological data long accumulated by monitoring programs have value but fail to provide the integrated system-wide perspective required for adaptive management and the Clean Water Act. Use of existing data may be limited by methodological incompatibilities, access difficulties, and the exclusive applicability of data to specific habitats or sites. The transition from site-specific to system-wide assessments benefits from research being done by USEPA's Environmental Monitoring and Assessment Program (EMAP) and other programs that use probability surveys and biological indicators. Indicators of various taxa (in particular fish, algae, and benthic invertebrates) have been successfully developed for great rivers. However, optimizing the information these ecological indicators convey to managers and the public is the subject of ongoing research.

AN - 70179039; 16983862 AB - In this research, the authors sought to provide experimental data on indoor air quality, and the resulting respiratory impact, for a high-elevation (4550 m), rural community in Ladakh, India. This community is of interest because the primarily nomadic residents burn biomass inside the home for heating and cooking. The concentrations of particulate matter (PM), endotoxin, and carbon monoxide were determined for 6 homes. Lung function data and induced sputum samples were collected for 9 female test-home subjects. In addition, lung function data were collected for 84 additional Ladakhi highlanders at this location. Sputum from 3 visiting scientists (sojourners) was collected and analyzed as well. The average PM concentration ranged from 2 mg/m3 to 7 mg/m3, with 85% of the sampled PM sized as respirable. The average endotoxin concentration ranged from 2.4 ng/m3 to 19 ng/m3, and average carbon monoxide levels ranged from 50 ppm to 120 ppm. Lung function values for the highlander population and the test-home subjects were equal to or greater than predicted, despite the highlanders' significant exposure to indoor pollutants. An induced sputum analysis revealed a significantly greater total inflammatory cell count (M +/- SD, 10(5) cell/mg) in the Ladakhi natives than in the sojourners (107.5 +/- 75.2 vs 7.1 +/- 8.1, p < .01). Although the high levels of indoor pollutants did not correlate with significant decrements in lung function, the induced sputum analysis revealed marked airway inflammation dominated by macrophages and neutrophils. It appears that augmented lung mechanics of this high-altitude population are adaptive to reduce the work of breathing; thus, decrements in lung function go undetected because the true predicted values are greater than expected.

AN - 68439937; 16076725 AB - Arsenic (As) is found naturally in the geological strata within the Ba Men Region of Inner Mongolia, China. A study was conducted to compare the total As measurements from two analytical techniques: instrumental neutron activation analysis (INAA) and atomic fluorescence spectrometry (AFS), and to verify nails as an exposure biomarker in this population. In 1999, nail and water samples were collected in a pilot study. Fingernails and toenails were pooled from 32 participants and analysed for total As by both INAA and AFS. Mean nail As values were 14.8+/-2.4 and 19.4+/-2.8 microg g-1 (+/-SEM) for INAA and AFS, respectively. Results from these two methods were significantly correlated (r=0.93, p<0.0001). In 2000, a second study was conducted and INAA was used to measure total As in toenails from 314 Ba Men residents. Well water samples were collected from 121 households and analysed by AFS. A significant correlation was observed between toenail and well water As (r=0.84, p<0.0001). Based on the results, INAA was significantly correlated with AFS and proved to be a reliable measure of nail As levels. In this population, toenail samples are a useful internal As exposure biomarker from drinking water sources.

The International Life Sciences Institute Risk Science Institute (ILSI RSI) convened an Expert Working Group to develop guidance on the design and implementation of direct dosing regulatory studies on preweaning mammals, which was published as an ILSI monograph in 2003 (Zoetis and Walls, Principles and Practices for Direct Dosing of Pre-Weaning Mammals in Toxicity Testing and Research, Washington, DC: ILSI Press, 2003). A summary of the Working Group conclusions regarding direct dosing studies with laboratory rodents are presented here, although the ILSI monograph also includes rabbits, canines, swine and nonhuman primates. Issues to be considered when designing the protocol include selection of the test species, the route of administration, dose levels, and the timing of dosing. Knowledge of the maturational status of the test species and information on critical windows of development are important in creating a valid study design. Most common routes of administration (e.g., oral, inhalation, injection) are possible with typical laboratory species; however, adjustments may be necessary due to practical considerations. Information on the pharmacokinetic profile in young animals versus adults and in the test species versus humans is very useful for determining dosing parameters. The conduct of the study and the interpretation of the data will be improved by an understanding of confounding factors as well as statistical and biological issues specific for postnatal studies. Ultimately, the success of the study will depend upon careful preparation, including thorough training of the technical staff.

AN - 67889790; 15931957 AB - Data from 13 National Atmospheric Deposition Program Mercury Monitor Network (NADP/ MDN) monitoring stations (1996-2002) and the Underhill (VT) event-based monitoring site (1993-2002) were evaluated for spatial and temporal trends. More precipitation and mercury deposition occurred in the southern and coastal MDN sites, except for the Underhill site, which received more mercury deposition than surrounding sites. Precipitation patterns varied. Regionally, higher concentrations of mercury were recorded during the late spring and summer months. Several sub-regional clusters of MDN sites were evident, based on mercury deposition patterns. In general, more mercury was deposited during the summer months. "Enhanced" weekly deposition (> 250 ng/m2) and distinct seasonal deposition patterns were evident at all MDN sites. Regionally, high depositional periods contributed significantly to annual loads (< 20%- approximately 60%). Southern and coastal sites measured more frequent periods of high deposition than inland sites. Spring and summer "enhanced" deposition may be important contributing factors to mercury bioaccumulation during the growing season. Recent regional reductions of mercury emissions were not reflected in the regional mercury concentration or deposition data. Few sites showed linear relations between the concentration of mercury in precipitation and acid rain co-contaminants (sulfates and nitrates).

AN - 67889767; 15931973 AB - Ecological risk assessments for mercury (Hg) require measured and modeled information on exposure and effects. While most of this special issue focuses on the former, i.e., distribution and fate of Hg within aquatic food webs, this paper describes an approach to predict the effects of dietary methylmercury (CH3Hg) on populations of piscivorous birds. To demonstrate this approach, the U.S. Environmental Protection Agency's National Health and Environmental Effects Research Laboratory (U.S. EPA NHEERL) is working cooperatively with environmental and conservation organizations to develop models to predict CH3Hg effects on populations of the common loon, Gavia immer. Specifically, a biologically-based toxicokinetic model is being used to extrapolate CH3Hg effects on the reproduction of a tested bird species, the American kestrel (Falco sparverius), to the loon. Population models are being used to incorporate stressor effects on survival and reproduction into projections of loon population effects. Finally, habitat and spatially-explicit population models are being used to project results spatially, assess the relative importance of CH3Hg and non-chemical stressors, and produce testable predictions of the effects of biologically-available Hg on loon populations. This stepwise process provides an integrated approach to estimate the impact on wildlife populations of regulations that limit atmospherically-distributed Hg, and to develop risk-based population-level regulatory criteria.

AN - 67796687; 15869190 AB - Data were collected from 60 boatable sites using an electrofishing design that permitted comparisons of the effects of designs and distances on fish assemblage metrics. Sites were classified a priori as Run-of-the-River (ROR) or Restricted Flow (RF). Data representing four different design options (i.e., 1000 and 2000 m for both single and paired banks) were extracted from the dataset and analyzed. Friedman tests comparing metric values among the designs detected significant differences for all richness metrics at both types of sites and for catch per unit effort and percent tolerant species at ROR sites. Richness metrics were generally higher for the two 2000-m designs than for the two 1000-m designs. When plotted against cumulative electrofishing distance, the percent change in metrics declined sharply within approximately 1000 m, after which metrics usually varied by less than 10%. These data demonstrate that designs electrofishing 1000 m of shoreline are sufficient for bioassessments on boatable rivers similar to those in this study, regardless of whether the shoreline is along a single bank or distributed equally among paired banks. However, at sites with depths greater than 4 m, it may be advisable to employ nighttime electrofishing or increase day electrofishing designs to 2000 m.

AN - 67504307; 15758093 AB - Methyl bromide (MeBr) is one of the most widely used soil fumigants. Human exposure to MeBr above threshold values can cause serious health problems. The exposure assessment of MeBr depends on estimation or measurement of its air concentrations. This study proposed a methodology for systematically exploring the empirical relationship between MeBr use intensity and ambient air concentrations. Monitored air concentrations were regressed to MeBr use over various spatiotemporal scales that step-wise increased around the monitoring site and monitoring period. The results showed that the goodness-of-fit varied with the spatiotemporal scale of MeBr use. The best fit was Y = 0.46 + 0.00120X (R2 = 0.95, n = 11), where Y was the 8-wk average ambient air concentration (microg/m3), and X was the weekly average use (kg/wk) over an area of 11.3 x 11.3 km (7 x 7 mi). The model was calibrated with air-monitoring data and use data of 2000, and verified with the same type data of 2001. The model estimated subchronic air concentration with reasonable accuracy.

AN - 67472524; 15734280 AB - Experimental models and clinical data indicate that the incidence of motor and learning disorders may be increased in children of epileptic mothers taking phenytoin (PHT) during pregnancy. There is little data on the vulnerability of infants to PHT-induced long-term behavioral toxicity after gestational or early life exposure (i.e., infantile convulsion therapy). We examined the persistence of alterations in circling behavior induced by exposure to PHT during gestation, infancy, or both. Pregnant Sprague-Dawley rats were injected i.p. with saline (SAL) or PHT (30 mg/kg/day) during gestational days (GD) 10-18. The offspring were then administered (i.p.) SAL or PHT (60 mg/kg/day) during postnatal days (PD) 13-23. Afterward, Circling Training tests were performed at three time points. At PD40 and PD80, the clockwise direction of circling was reinforced. At PD150, counterclockwise circling was rewarded instead. At PD40, all PHT-treated groups demonstrated increased circling velocities compared to saline-treated controls. Higher spatial error rates for direction of circling were also observed in gestation-only and infancy-only exposures. At PD80, groups exposed during gestation had higher circling velocities than control or infancy-only exposed groups. At PD150, increases in circling velocity were apparent for the reverse learning task in groups exposed during gestation. These results indicate that early postnatal exposure to PHT may exacerbate the known long-term behavioral effects of gestational exposure.

Based on laboratory findings, this study presents the design of a pilot-scale remediation at an operating electroplating site. The fine-textured soil developed from Jurassic limestone exhibits a chromium, copper, nickel, and zinc contamination down to depths of more than 4 m. The feasibility of an electrokinetic remediation in the unsaturated zone was tested in a lab-scale experiment with subsoil material sampled at the site. The electrodes were placed in water-impermeable, ion-selective membrane wells. This construction allows the necessary watering of the electrodes, maintains unsaturated conditions in the soil compartment, and enables the transfer of contaminant ions into the wells. In addition, the soil is protected from pH changes caused by water electrolysis at the electrodes. The setup includes a watering and drainage system to compensate the electroosmotic water flux and impede desiccation of the anodic region. With a direct current of 70 V and an electric field strength of 2.2 V cm (super -1) , contaminant removal rates amounted up to 27% and 66% (w/w) of the initial zinc/copper and chromium/nickel concentrations. Copper, nickel, and zinc accumulated in the cathode well, while chromate species were enriched in the anode well. Given the successful lab-scale remediation, the pilot plant was designed for the in-situ treatment of a soil volume of 12 m (super 3) below a production hall. A power of 500 V DC at a maximum current of 30 A is supplied by a transformer rectifier. This yields an electric field strength comparable to the lab-scale experiment and thereby similar contaminant transport velocities. A vacuum distillation unit is employed for process water reuse and to control electrolyte conductivity. To cope with chlorine gas generation at the anodes a gas absorber unit is employed.

X-ray diffraction patterns of the coprecipitates show two broad peaks at 0.149 and 0.258 nm, which is consistent with published patterns for pure 2-line ferrihydrite. Zn (super 2+) uptake occurred at pH> or =5 while Fe (super 3+) precipitation occurred between pH 3 and 4, although both Zn (super 2+) and Fe (super 3+) were present in the same solution during the entire range of pH titration. High-resolution transmission electron microscopy shows that the coprecipitates are 2 to 6 nm sized single crystalline particles but aggregated to 50 to 400 nm sized clusters. Analytical electron microscopy indicated that the 5% atomic Zn with respect to Fe was homogeneously distributed. No segregated phases were found in the clusters or at single crystal edges, which is consistent with published extended X-ray absorption fine structure (EXAFS) results at similar Zn/(Zn + Fe) ratios. Hence, occlusion and surface precipitation may be excluded as possible coprecipitation mechanisms. The bulk solution Zn (super 2+) sorption edge was fitted to both solid solution and generalized diffuse layer surface complexation models. However, a solid solution model is inconsistent with published EXAFS results that show tetrahedral polydentate Zn (super 2+) complexes sharing apices with Fe (super 3+) octahedra.

Overburden arsenic data cluster in the range of 20 to 50 ppm of extractable As, but can reach values well in excess of 500 ppm. Although, the distribution pattern and source of arsenic is still a subject of ongoing studies, the ground waters percolating through overburden strata (and bedrock as well) often show also elevated arsenic, commonly in excess of the 10 ppb limit set by the EPA (typically 20 to 500 ppb). The mechanism of arsenic uptake to ground water (which is not the focus of this paper) appears to be either (1) presence of a reducing environment in the overburden; and/or (2) oxidation of As bearing sulfides in the bedrock. In this paper we present data on arsenic concentration in bottom sediments from ponds proximally located near the eastern margin of the elevated arsenic zone. Samples of bottom sediments from a series of ponds reveal a pattern that correlates with the hydrologic regime of the area; three distinct groups of As concentrations are observed. One group of samples from an area not affected by the contaminated groundwater flow has As in the dried sediments in the 20 to 50 ppm range (same as the surrounding overburden). A second group of samples has a range between 80 and 150 ppm. This group corresponds to a discharge zone of groundwater contaminated by As in the range of 30 to 190 ppb. The last group is a sequence of samples with a steep progressive range from 200 to 7000 ppm. This group is correlated with a historic and ongoing contribution of highly contaminated ground water containing dissolved arsenic from 300 to 2000 ppb. Our study confirms cycling of arsenic from the overburden: (1) arsenic transfer from the overburden (solid phase) to ground water (dissolved), (2) ground water transport of arsenic into the surface waters and ponds; and (3) arsenic removal and accumulation in the pond bottom sediments (solid phase). During the discharge of arsenic contaminated ground water into the oxidized waters of the ponds, hydrous ferric oxide precipitates and concurrently absorbs dissolved arsenic species all accumulating in the pond bottom sediments. Arsenic accumulation over time can reach proportions that may pose a significant risk to the environment.

The first task in developing a depth to water-table grid is to construct a water-table elevation grid. United States Geological Survey (USGS) Digital Line Graph-100 surface hydrology data, USGS Digital Elevation Model (DEM) and USGS Ground Water Site Inventory data were used to construct a water-table elevation point coverage for NYS. The GIS geostatistical method of interpolation known as kriging (Burrough and McDonnell 1998) was used to create a water-table elevation surface (grid). The regional depth to water-table grid was created by subtracting the water-table elevation grid from the USGS DEM.

A Standard Industrial Classification (SIC) code environmental-risk database (Hillenbrand and Eckman, in press) was used in combination with a Dunn and Bradstreet facility data layer to create a facility point coverage that was environmentally risked by SIC code. GIS summarization analysis of the environmentally risked facility coverage within the United States Geological Survey (USGS) Multi-Resolution Land Classification (MRLC) grid yielded a total risk value for each land use classification. This value was divided by the total area of each land use classification to yield an average SIC code environmental-risk value per cubic meter for each land use classification. These values allowed the construction of a NYS land use environmental-risk grid. This grid assesses a regionally scaled potential to introduce contaminants to the environment in NYS.

Hypophysectomy was performed by the partial decapitation technique. At 44-46 h of incubation, chick embryo heads were sectioned at the mesencephalic level and the prosencephalic region removed. Embryos were further incubated until 8-14 days of development. Cell division was evaluated by bromodeoxyuridine (BrdU) incorporation and by counting the total number of somatic and germ cells in the gonads. The ovary displayed an exponential increase in the number of somatic and germ cells and a higher rate of BrdU incorporation compared to the testis. BrdU incorporation was reduced in the ovary of hypophysectomized embryos at 9-14 days of incubation, while in the testis, the reduction was significant at 14 days of development. Changes in the total number of somatic and germ cells further suggest that the absence of hypophysis affects the growth of the ovary earlier than the growth of the testis. Reduction in the number of somatic and germ cells after hypophysectomy in the ovary was reversed by a hypophyseal graft on the chorioallantoic membrane. The adenohypophysis regulates, probably through gonadotropic hormones, proliferation of somatic and germ cells in the gonads during chick embryo development. J. Exp. Zool. 303A:179-185, 2005.

We developed a harshness index that quantifies ecologically pertinent spatial and temporal characteristics of prairie intermittent streams that may limit or reduce diversity and abundance to predict benthic macroinvertebrate assemblage characteristics. The index incorporates 11 variables that describe the hydrological regime (e.g. average flow, flow variability, drying and flooding) and distance to perennial surface water. We started with 27 variables, but removed 16 that did not increase the predictive value of the index. The relationships among index values and annual mean macroinvertebrate assemblage characteristics (taxonomic richness, diversity, evenness and abundance) were tested over two years using seven sites that represent a range of flow permanence (recent and historical), flood magnitude (recent and historical) and surface-water connectivity. Mean annual taxonomic richness was significantly related to the harshness index. Evenness and abundance were not related to harshness. Further analyses indicated that distance to the nearest permanent habitat was less important than annual or historical hydrological parameters, even though prior research had documented higher rates of colonisation at sites that were closer to nearest permanent habitat. Both annual factors that can alter abundance and colonisation immediately (e.g. floods, drought in each year) and historical factors (e.g. probability of drying, average length of dry period over decades) may influence assemblage characteristics. Historical factors may influence evolutionary adaptations of invertebrates and may predominate when relative disturbance rates are lower such as in years with less flooding.

More than a decade of PM research has demonstrated that these effects do not occur indiscriminately and are related to particle size, surface area, and chemical composition. Experimental evidence in rodents indicates that inhaled or instilled diesel exhaust particles (DEPs) increase lung injury, inflammation, and allergic airway responses, and that ultra-fine carbon black (UFCB) particles cause more pulmonary inflammation than fine carbon black (FCB) particles in a dose-dependent manner. Our preliminary work determined that a dose of 100 mu g of FCB, UFCB, or DEPs (NIST SRM 2975) was sufficient to enhance pulmonary inflammation in Brown Norway (BN) rats 24 hours after intratracheal (IT) instillation of the particles. In the current investigation, we sought to compare, on a mass basis, the effects of a 100 mu g dose of these particles on allergic sensitization to house dust mite (HDM) antigen. Immediate airway responses (IAR) to HDM challenge and a battery of proinflammatory, allergic, and acute injury responses in the lung were then measured two and seven days post-challenge. DEPs exposure increased 8 of 10 responses including IAR and levels of IL-4, IL-13, TNFa, total protein, cysteinyl leukotrienes, and eosinophils in bronchoalveolar lavage fluid (BALF). UFCB and FCB significantly enhanced 4 of 10 and 2 of 10 of these responses compared to saline, respectively. Among other responses that were not statistically elevated with particle treatment, mean values for FCB were higher than for UFCB. Particles administered prior to challenge rather than prior to sensitization did not significantly enhance any of these responses above levels of saline controls. We conclude that on a mass basis, DEPs had the greatest potential to enhance allergic induction, indicating that chemical composition is more important than particle size in determining potency for this health effect.

These strains have been identified by 16S rRNA sequencing and phylogenetic analysis as belonging to the Flavobacterium columnare clade of the Cytophaga-Flavobacterium group. While the cyst degradation mechanism is unclear, two different effects on the cysts were observed: non-viability and lysis. Cysts exposed to bacterial strains BR1 and SC1 were generally non-viable, but remained structurally intact. In contrast, cysts exposed to strain SR1 were clearly lysed. Increases in bacterial densities with a concomitant decrease in cyst viability suggest that these bacterial strains are capable of using the cysts to enhance their growth. We propose that the presence of bacterial strains such as SR1, BR1 and SC1 may play a role in reducing the viability of G. intestinalis cysts in natural waters.

A combination of radiometric dating, historical data, fossil markers and mineral magnetics has been used to develop a sediment chronology for the billabong that extends from about AD 1120 to the present. Fossil pollen and diatoms have been used to provide a high-resolution record of vegetation and aquatic ecosystem change through this period, with the aim of developing a better understanding of human disturbance in floodplain lakes. Specifically we aim to investigate the development and trajectory of eutrophic and turbid conditions that exist in the lake at present. The pre-European contact diatom assemblage at Bolin Billabong is dominated by a planktonic taxon, Cyclotella stelligera, and had very low diversity, with little evidence of species turnover. This suggests that the billabong had low nutrient concentrations and contrasts with the generally accepted notion of billabongs as naturally diverse, productive and variable systems. The initial period of European occupation was characterized by catchment disturbance with high levels of erosion and sedimentation. Sedimentation rates in the post-European contact period appear to be 30 times higher than prior to European settlement. Evidence suggests that the Yarra River was not naturally turbid. Changes to the diatom assemblage, reflective of water quality perturbation following European contact, were dramatic and unprecedented. Following an initially high sedimentation rate in the post- European contact period, the sedimentation rate gradually slowed towards the present day. The increase in nutrients available to the diatom assemblage appears to have been moderate from European contact (c. AD 1840) to until around AD 1920, then more pronounced from this point onwards. Recent changes in the diatom assemblage at Bolin Billabong appear moderate compared with other regulated river floodplain sites studied in southeastern Australia.

The objectives of this study were to examine the relationship between gross N transformation rates and microbial populations and to investigate the role that SOM plays in these factors. In our study, culturable microbial and actinomycete populations were positively correlated with gross mineralization and ammonium (NH sub(4) super(+)) consumption rates over time in both ecosystems. These correlations provide evidence that microbial plate counts could be a good representation of all microbes responsible for gross mineralization and gross NH sub(4) super(+) consumption. Rates of gross mineralization, nitrification and NH sub(4) super(+) consumption were significantly greater in forest soil than old-field soil. These greater rates in forest soil could be due to the presence of higher levels of readily transferable substrates in SOM. Gross nitrification rates were considerably lower than gross mineralization and NH sub(4) super(+) consumption rates over the experimental period, indicating heterotrophic uptake of NH sub(4) super(+) rather than use by autotrophic nitrifiers under soil and environmental conditions in this study. Additionally, microbial populations were significantly (p<0.01) greater in forest soil than in old-field soil, which could also be related to the higher level of SOM in the forest soil. Net mineralization and nitrification rates were similar between ecosystems. Results also showed that net rates were highly correlated to each other, but were not correlated with culturable microbes or gross N transformation rates, indicating the isolation of net rates in relation to fundamental controlling factors.

An improved method was developed to determine the air flow rate for a shelter inside a house. Expedient sheltering measures (plastic sheeting and duct tape) were applied to a room inside a test house by participants who followed the DHS guidance. Measured air flow rates were used to determine protection factors for various scenarios. Protection factors were calculated for the house and shelter under various occupancy times, weather conditions, and outdoor exposure times for hazardous agents. Protection factors ranged from 1.3 to 539, depending on the conditions. Results indicate that proper sealing can make a substantial difference in the effectiveness of the shelter. Sheltering in place can be most beneficial if people enter shelters before the arrival of a cloud of hazardous agent, and people exit shelters as soon as the cloud passes over. However, sheltering in place can be detrimental if people enter or exit shelters too late. CO sub(2) and O sub(2) concentrations inside the shelter are not likely to reach dangerous levels under most scenarios, but concentrations could reach dangerous levels under certain conditions, and concentration levels could affect individuals with respiratory problems.

The RSSCTs were conducted using Ambersorb 563 carbonaceous resin (Rohm and Haas Corp., Philadelphia, Pa.) under multisolute conditions of typical municipal water source, soluble fuel components or additive/by-product, and MTBE. Specifically, one RSSCT column run was conducted with groundwater from Arcadia Wellfield, Santa Monica, Calif., with tert-butyl alcohol (TBA) and MTBE, while the other RSSCT column run was performed with surface water from Lake Perris, Calif., with benzene, toluene, p-xylene (BTX) and MTBE. The results obtained were compared to RSSCTs performed using PCB coconut shell granulated activated carbon (GAC) (Calgon Corp., Philadelphia, Pa.). The adsorbent comparisons indicate that the performance (as characterized by indicators such as carbon usage rates or integrated column capacity) of the Ambersorb 563 synthetic resin in multisolute conditions of TBA or BTEX with MTBE in typical municipal water source is significantly superior to that of the coconut shell PCB GAC. Cost comparison for the coconut shell GAC and synthetic resin system was also performed. Under multisolute conditions of typical municipal water source, flow rates, and influent MTBE concentrations, the cost of the resin system, for most of the scenarios evaluated, is demonstrated to be significantly lower than the complementary GAC system under the costing procedure used. Further, when soluble fuel components such as BTX or fuel additives/byproducts such as TBA were present along with MTBE, the predicted higher adsorbent usage rates for the coconut shell GAC were translated into significantly higher treatment costs relative to the synthetic carbonaceous resin system.

ER - TY - JOUR T1 - Projected population-level effects of thiobencarb exposure on the mysid, Americamysis bahia, and extinction probability in a concentration-decay exposure system AN - 19414434; 6236678 AB - Population-level effects of the mysid, Americamysis bahia, exposed to varying thiobencarb concentrations were estimated using stage-structured matrix models. A deterministic density-independent matrix model estimated the decrease in population growth rate ( lambda ) with increasing thiobencarb concentration. An elasticity analysis determined that survival of middle stages provided the largest contribution to lambda . Decomposing the effects of lambda in terms of changes in the matrix components determined that reduced reproduction had a large influence on population dynamics at lower thiobencarb concentrations, whereas reduced survivorship had the largest impact on populations at higher concentrations. A simulation model of a concentration-decay system was developed to demonstrate the importance of integrating chemical half-life and management practices in determining population viability. In this model, mysids were originally exposed to a high thiobencarb concentration (300 mu g/L) that decayed an order of magnitude in the number of mysid generations corresponding to thiobencarb half-life values under three different exposure regimes. Environmental stochasticity was added to the model to estimate the cumulative extinction probability of mysids exposed to fluctuating concentrations of thiobencarb in random environments.

In turn, macrodetritivores may be influenced by plant species composition via their selection of optimal food resources and habitats. In our experiment, fertilizer had no apparent effect on litter decomposition, suggesting that microbial decomposers did not use the additional inorganic N and/or that macrodetritivores had a greater influence on decomposition. Manipulation of macrodetritivores suggested that plant species composition--dominated in this study by Festuca arundinacea, an exotic, invasive grass, and Aster ericoides, a native forb--caused shifts in detrivore communities and/or feeding patterns that tended to increase litter mass loss. Canopy cover of F. arundinacea and A. ericoides ranged from 0% to 11%, suggesting that low-intensity invasion may produce significant changes in ecosystem function, such as decomposition.

Published data are lacking on the effects of acute exposure to molinate in the female. Based on this work and our previous observations with related dithiocarbamate compounds, we hypothesized that a single exposure to molinate during the critical window for the neural trigger of ovulation on the day of proestrus (PRO) would block the luteinizing hormone (LH) surge and delay ovulation. To examine the effect of molinate on the LH surge, ovariectomized (OVX) rats were implanted with Silastic capsules containing estradiol benzoate to mimic physiological levels on proestrus. Doses of 25 and 50 mg/kg molinate significantly suppressed LH and prolactin secretion. Intact regularly cycling females gavaged with 0, 25, or 50 mg/kg molinate at 1300 h on PRO were examined on estrus or estrus +1 day for the presence of oocytes in the oviduct. All control females had oocytes in the oviduct on estrus. Molinate doses of 6.25 to 50 mg/kg delayed ovulation for 24 h. Estrous cyclicity was examined after daily exposure to 50 mg/kg (21 days). Estrous cyclicity was irregular in the molinate group, showing extended days in estrus. Two experiments were conducted to determine whether molinate blocked the LH surge via a central nervous system (CNS) mode of action or via an alteration in pituitary response. In the first experiment, we evaluated the release of LH in control and molinate-treated rats after a bolus dose of exogenous GnRH. Luteinizing hormone release was comparable in the two groups, suggesting that the effect of molinate is centrally mediated. To further examine the potential role of the CNS, we examined the pulsatile release of LH present in the long-term OVX females. In this model, the pulsatile pattern of LH secretion is directly correlated with GnRH release from the hypothalamus. A significant decrease in the LH pulse frequency was observed in molinate-treated females. These results indicate that molinate is able to delay ovulation by suppressing the LH surge on the day of proestrus and that the brain is the primary target site for the effects on pituitary hormone secretion.

For those species with multiple breeding attempts per breeding season, variance in fecundity is best explained by the number of breeding attempts. For birds, multiple brooding may be influenced by food availability. Here, we report results of a food supplementation experiment that tests the role of food as a mechanism driving variation among individuals in the frequency of multiple brooding in a Neotropical migrant songbird, the Black-throated Blue Warbler (Dendroica caerulescens). Supplementally fed females produced more second broods, spent less time foraging and more time loafing, and stayed closer to their nests than did control females. Fed and control females did not differ in the number or mass of young fledged from the first nesting attempt. Supplemental food increased the probability that females would initiate second broods in both a low and an average food year, suggesting that this population is food limited during the breeding season in most years. Our results thus demonstrate that food availability can strongly influence annual fecundity in migratory bird species breeding in temperate forests, which, in turn, affects annual recruitment rates and population size.

The method presented assumes moments are calculated by numerical integration using the trapezoidal rule, and is theoretically applicable to moments of any order. Moreover, the method is applicable to either temporal or volumetric moments, and in the latter case, explicitly accounts for errors in volume measurements. The complexity of the calculations for the zeroth moment is comparable to that associated with the typical propagation-of-errors formula based on a Taylor series expansion. However, the formulae for higher moments are substantially more complex than the typical propagation-of-errors formula. For the zeroth and normalized first moments, moment uncertainties are more sensitive to random errors in concentration measurements compared to random errors in volume measurements. The robust nature of moment calculations is exemplified by the fact that relative uncertainty in moments is less than the relative error in volume and concentration measurements. Furthermore, moment uncertainty decreases as more data points are collected to define the BTC. For a BTC (based upon the solution to the one-dimensional advective-dispersion equation with a Peclet number of 10) with 100 data points, the zeroth moment and normalized first moment coefficient of variations are approximately 6 and 2%, respectively, for concentration coefficient of variation equal to 25% over a range of volume errors.

Creation of GIS databases for hydrography, hydrologically corrected digital elevation models, and hydrologic derivatives such as watershed boundaries and upstream-downstream topology of subcatchments would provide a consistent seamless nationwide framework for these designs. The elements of a watershed-based sample framework can be represented either as a continuous infinite set defined by points along a linear stream network, or as a discrete set of watershed polygons. Watershed-based designs can be developed with existing probabilistic survey methods, including the use of unequal probability weighting, stratification, and two-stage frames for sampling. Case studies for monitoring of Atlantic Coastal Plain streams, West Virginia wadeable streams, and coastal Oregon streams illustrate three different approaches for selecting sites for watershed-based survey designs.

U.S. Department of Health and Human Services, National Institutes of Health, Washington, DC]). Since the last EGBE IRIS assessment, a number of studies have provided evidence that the carcinogenic effects observed in mice are nonlinear in their mode of action and may be dependent on threshold events such as EGBE- induced hemolytic effects. EPA is in the process of considering several questions relating to this issue. First, can a plausible mode of action be determined for the two types of tumors observed in mice? Second, are the mechanisms involved applicable to humans? If so, should the mode of action be considered to result in a linear or nonlinear dose-response? These questions will be addressed within the context of the agency's new cancer guidelines and with regard to how the answers might affect a revised IRIS assessment for EGBE.

AN - 17629664; 6208569 AB - The presumed relationship between economic growth and salmon conservation is the unstated basis for many of the contentious policy deliberations now occurring in western North America. Economic growth is "a sustained rise in a nation's production of goods and services" (National Council on Economic Education 2003). In other words, economic growth occurs when the product of population and per capita production (and consumption) is increasing, and is indicated by increasing GDP. Blunt discussions of the relationship between economic growth and the future of salmon are uncommon, perhaps understandably in part because such discussions would likely highlight the difficult, divisive policy choices that, from the perspective of some policy makers and advocates, are best left unarticulated. Rather than blunt and candid dialog, a "conspiracy of optimism" seems to reign in most discussions concerning the prospects for salmon recovery. Most salmon policy discussions tend to focus on the proximal causes, the agents of the decline, and how these agents must be altered to achieve and sustain higher levels of salmon abundance. Scientists have long recognized these proximal causes of the decline, but there remains uncertainty about their relative importance. Attempts at serious discussion about future policy options regarding wild salmon in California, Oregon, Washington, Idaho, and southern British Columbia quickly lead to an apparent conundrum, one of accommodating anticipated economic (including human population) growth while concurrently restoring biologically significant, sustainable runs of wild salmon.

A significant difference between the ratio of observed (O) and expected (E) taxa (O/E) and 1.0 indicates that the site is not in reference condition. The standard deviation (SD) of O/E values estimated for a set of reference sites is a measure of predictive-model precision, with a small SD indicating that the model accounts for much of the variability in E that is associated with natural factors such as stream size and elevation. We propose a null model for E that assumes fixed occurrence probabilities for individual taxa across reference sites. The null model explains none of the variability in E caused by natural factors, so the SD of its O/E predictions is the upper limit attainable by any predictive model. We also derive a theoretical lower limit for SD of O/E that is caused only by replicate-sampling variation among predictions from a perfect model. Together, the null-model and replicate-sampling SDs estimate the minimum and maximum precision, respectively, attainable by any predictive model for a given set of reference-site data. A predictive model built from data at 86 reference sites in the Mid-Atlantic Highlands region, USA, had SD = 0.18 for O/E across those sites, while the corresponding null model had SD = 0.20, indicating relatively little gain from the predictive-model effort. In contrast, a model built from 209 sites in North Carolina, USA, had predictive- and null-model SDs of 0.13 and 0.28, respectively, indicating that the North Carolina predictive model had relatively high gain in precision over the null model. Replicate-sampling SDs of O/E for the Mid-Atlantic and North Carolina data were 0.09 and 0.11, respectively, suggesting that the North Carolina predictive model had little room for further improvement, in contrast to the Mid-Atlantic model. The precisions of null-model estimates were lower than those of predictive models, so null models somewhat underestimated the percentages of 447 and 1773 test assemblages from the Mid-Atlantic region and North Carolina, respectively, that differed significantly from reference conditions. The estimates illustrate how a simple and easily built null model provides a lower bound for the prevalence of impaired streams within a region.

Mesquite shrubs were removed from nine plots, six plots were grazed by yearling cattle in August and six plots were grazed in February for the last 3 years of the 5 year study. Arthropod species richness ranged between 154 and 353 on grasses, from 120 to 266 on G. sarothrae, and from 69 to 116 on P. glandulosa. There was a significant relationship between the number of families of insects on grass and G. sarothrae and growing season rainfall but species richness was not a function of growing season rainfall on any of the plants. Several of the arthropod families that were the most species rich in this grassland were found on all of the plants sampled, i.e. Salticid spiders, Bruchid and Curculionid beetles, Cicadellid and Psyllid homopterans, and ants (Formicidae). There were more species rich families that were shared by grasses and the sub-shrub G. sarothrae than with mesquite. The absence of a relationship between growing season rainfall and species richness was attributed to variation in life history characteristics of arthropods and to the non-linear responses of annual and perennial desert grassland plants to rainfall. There were no significant differences in insect family or species richness on any of the plant types as a result of removal of mesquite (P. glandulosa) from selected plots. Intense, short duration (24h) grazing by livestock during in late summer resulted in reduced species richness in the grass-herb vegetation layer but had no effect on insect species richness on snakeweed or mesquite shrubs. Livestock grazing in winter had no effect on insect species richness on any of the vegetation sampled.

Initially, the isotopic approach was used to identify sources of organic matter and to determine their fate in estuarine food webs. Results obtained with this technique were qualitative; however, more recent attempts to quantify sources or processes have typically relied on simple 2 or at most 3 end-member mixing models. The key assumption is that sources can be defined by a discrete value. This assumption often does not hold and, more importantly, the isotopic variation observed within sources contains significant information. In contrast, inverse-modeling of estuarine carbon cycling has the advantage that ranges of field and laboratory measurements and historical information can be utilized by this method. We used the inverse approach to revisit the issue of a headwater delta's contributions to an estuarine food-web under conditions of low freshwater inflow and after a flood-induced inundation of the delta (Rincon Delta, discharging into Nueces Bay, Texas, USA). We illustrate how isotopic constraints enhance results obtained with more traditional constraint systems. The results suggest that although benthic infauna production is stimulated by increased water flow and delta freshwater inundations, most of the allochthonous carbon is exported from Nueces Bay.

These physical data were correlated with plant growth and other metrics measured at intervals during the study. Photosynthesis vs. irradiance (P vs. I) curves were determined by PAM fluorometry on plants along an intertidal gradient, and were used to estimate saturating irradiance (I sub(k)) and daily hours of saturating irradiance (H sub(sat)). Mean I sub(k) values were similar to 64 mu mol photons m super(-2) s super(-1) and H sub(sat) increased with increasing tidal position. Measurements taken during the second winter showed that H sub(sat) values in the low intertidal zone were within a critical range requiring eelgrass to use rhizome reserves to maintain carbon balance. However, plants continued to grow. Temperature differences across tidal gradients were not found to be physiologically important. These results suggested that temperature and irradiance were not limiting factors for intertidal Z. marina growth. High intertidal eelgrass, exposed to aerial conditions more frequently and for longer durations, exhibited signs of desiccation damage and appeared to have faster blade turn-over rates in spring and summer than their low intertidal neighbors. Thus, we concluded that the major factor limiting Z. marina in the upper intertidal zone was desiccation stress, which was acute and episodic rather than chronic.

Methods used to calculate risk estimates of mixtures were often based on single chemical information that required assumptions of dose- addition or response-addition and did not consider possible changes in response due to interaction effects among chemicals. Full factorial designs for laboratory studies can produce interactions information, but these are expensive to perform and may not provide the information needed to evaluate specific environmentally relevant mixtures. In this research, groups of Japanese medaka (Oryzias latipes) embryos were exposed to binary mixtures of benzene and toluene as well as to each of these chemicals alone. Endpoint specific dose- response models were built for the hydrocarbon mixture under an assumption of dose-additivity, using the single chemical dose-response information on benzene and toluene. The endpoints included heart rate, heart rate progression, and lethality. Results included a synergistic response for heart rate at 72 h of development, and either additivity or antagonism for all other endpoints at 96 h of development. This work uses an established statistical method to evaluate the toxicity of an environmentally relevant mixture to ascertain whether interaction effects are occurring, thus providing additional information on toxicity.

This paper presents an analysis of metal concentrations in surface sediments from Lake Macquarie using normalisation models to estimate enrichment relative to natural background concentrations and by comparing concentrations with sediment quality guidelines (SQGs) and effects range median quotients to assess the potential for ecological harm. Of the 12 metals examined, cadmium, lead, mercury, selenium, silver and zinc were enriched in surface sediments throughout the lake. The greatest contamination was found in the north of the lake and, for selenium, also in areas adjacent to two power stations. Comparisons with SQGs and effects range median quotients found that sediments from a site in Cockle Bay had concentrations of metals with the highest likelihood of causing adverse effects on sediment associated biota, and that the likelihood adverse decreased with distance from Cockle Bay. Comparisons with historical sediment quality data indicated that there has been a marked reduction in surface metal concentrations throughout the lake over 15 years. Models could not be constructed for all metals due to low background concentrations. For most metals, simple linear regression models were adequate, but for selenium and arsenic a multiple regression model provided a better estimate of background concentrations.

The estimated t sub(1/2) of elimination for a bolus dose of TCDD in C. virginica is ~-14-24 days based on both the experimental data and the PBPK model. The highest dioxin concentration reached during 28-days was in the digestive gland followed by the mantle, gonad, hemolymph, gill, adductor muscle, and the kidney/heart. A binding protein for 2,3,7,8-TCDD had been reported in the literature for both the digestive gland and gonad. Incorporating a binding component in the model resulted in a better fit for the data. The PBPK model predicted the distribution and the elimination concentrations for 2,3,7,8-TCDD within each of the tissue compartments. This model will serve as a useful tool for predicting the kinetics of other persistent organic pollutants as well as, allow for a more refined ecological risk assessment by estimating dioxin concentrations in sensitive tissues such as the gonad.

No significant changes were detected in the concentrations of the dihalogenated haloacetic acids (DXAAs) (i.e. dichloro-, bromochloro-, dibromoacetic acid) upon boiling of chloraminated water, whereas the levels of the trihalogenated haloacetic acids (TXAAs) (i.e. trichloro-(TCAA), bromodichloro-(BDCAA), dibromochloroacetic acid (DBCAA)) decreased over time (e.g. 9-37% for TCAA). Increased DXAA concentrations (58-68%) were detected in the boiled chlorinated sample, which likely resulted from residual chlorine reacting with DXAA precursors. TCAA concentration was unchanged after boiling chlorinated water for 1 min, but a 30% reduction was observed after 5 min of boiling. BDCAA concentrations decreased 57% upon boiling for 1 min and were completely removed after 2 min of boiling, whereas DBCAA was removed after boiling chlorinated water for 1 min. Trihalomethane concentrations were reduced in both chloraminated (74-98%) and chlorinated (64-98%) water upon boiling. Boiling chloraminated water for 1 min reduced chloroform concentration by 75%. Chloroform was reduced by only 34% in chlorinated water after a 1 min boil, which indicates that simultaneous formation and volatilization of chloroform was occurring. Most of the remaining DBPs (e.g. haloketones, chloral hydrate, haloacetonitriles) were removed by at least 90% after 1 min of boiling in both samples. These data suggest that other mechanisms (e.g. hydrolysis) may have been responsible for removal of the non-volatile DBPs and further highlight the importance of examining individual species when estimating thermal effects on DBP concentrations.

Sampling occurs at various levels and times throughout an environmental site characterization process. Typically, initial (primary) sampling occurs in the field while subsequent stages of sample size reduction (subsampling) occur until the final laboratory analysis stage. At each step in the measurement process, from planning, site selection, sample collection, sample preparation, through sample analysis, errors can occur that propagate, leading to uncertainty associated with the final result upon which decisions will ultimately be made. The goal of all sampling efforts should be to select samples that are representative of the population (i.e., site) in question. General guidelines, with supporting background and theory, for obtaining representative subsamples for the laboratory analysis of particulate materials using "correct" sampling practices and "correct" sampling devices are presented ("correct" as defined by Gy sampling theory; see Pitard, 1993). Considerations are given to: the constitution and the degree of heterogeneity of the material being sampled, the methods used for sample collection (including what proper tools to use), what it is that the sample is supposed to represent, the mass of the sample needed to be representative, and the bounds of what "representative" actually means.

In this study, numerical experiments are carried out to test and compare various statistical techniques in the estimation of primary OC/EC ratios. The influence of random measurement errors in both primary OC and EC measurements on the estimation of the expected primary OC/EC ratios is examined. It is found that random measurement errors in EC generally create an underestimation of the slope and an overestimation of the intercept of the ordinary least-squares regression line. The Deming regression analysis performs much better than the ordinary regression, but it tends to overcorrect the problem by slightly overestimating the slope and underestimating the intercept. Averaging the ratios directly is usually undesirable because the average is strongly influenced by unrealistically high values of OC/EC ratios resulting from random measurement errors at low EC concentrations. The errors generally result in a skewed distribution of the OC/EC ratios even if the parent distributions of OC and EC are close to normal. When measured OC contains a significant amount of non-combustion OC Deming regression is a much better tool and should be used to estimate both the primary OC/EC ratio and the non- combustion OC. However, if the non-combustion OC is negligibly small the best and most robust estimator of the OC/EC ratio turns out to be the simple ratio of the OC and EC averages. It not only reduces random errors by averaging individual variables separately but also acts as a weighted average of ratios to minimize the influence of unrealistically high OC/EC ratios created by measurement errors at low EC concentrations. The median of OC/EC ratios ranks a close second, and the geometric mean of ratios ranks third. This is because their estimations are insensitive to questionable extreme values. A real world example is given using the ambient data collected from an Atlanta STN site during the winter of 2001-2002.

The evaluation included variations in sample air temperature, relative humidity and ozone concentration. Linearity of samples with loading was examined both for a constant concentration with time varied up to 24 h and for different concentrations over 24 h. Reverse diffusion and its increase with accumulation of sample were determined for all compounds. Tubes were examined for blank levels, change of blanks with storage time, and variability of blanks. Method detection limits were determined based on seven replicate samples. Based on this evaluation, 27 VOCs were selected for quantitative monitoring in the concentration range from approximately 0.1 to 4 ppbv. Comparison results of active and diffusive samples taken over 24 h and under the same simulated ambient conditions at a constant 2 ppbv were interpreted to estimate the effective diffusive sampling rates (ml min super(-1)) and their uncertainties and to calculate the corresponding diffusive uptake rates (ng ppmv super(-1) min super(-1)).

The simulation of emissions and emission controls was conducted using the Climate Change Risk Assessment Framework, which projects SO sub(2) and NO sub(x)emissions from energy consumption and conversion and non-energy sources. The analysis of resulting scenario-, region-, and gas-specific income-emission curves suggests that income alone as a model driver of future emissions cannot adequately capture all plausible future SO sub(2) or NO sub(x) emission pathways, or important differences among regions in those trajectories. Future social choices regarding the degree and strategy for environmental protection introduce large uncertainties in future projections and result in differing relationships between income and emissions.

AN - 67426494; 15705534 AB - Diverse agonists used for airway challenges produce a stereotypic sequence of immediate functional responses (e.g., bronchoconstriction, gas trapping, hypoxemia, etc.) at the time such reactions are triggered. The reaction incorporates both pulmonary and cardiac changes that clearly interact in an orchestrated fashion taking the subject (or animal model) through the response generally to ultimate recovery. We hypothesize that despite differences in the initiation of the response, diverse airway provocations lead to a cascade of events that converge through a common physiologic pathway. To better understand the sequence of events and the counterbalanced cardiopulmonary responses, we examined histamine, methacholine, and ovalbumin (OVA) challenges in the awake guinea pig model and assessed ventilatory and breathing mechanics in the context of associated cardiac parameters. With the histamine response as the prototype, we evaluated the role of beta-adrenoreceptors using propranolol (1.0-10 mg/kg i.p.) and found that beta-adrenoreceptors are critical in reducing challenge-induced gas trapping in the lungs. The disposition of the circulatory response to agonist challenge (the OVA model) was reflected in a significant absolute shunting of blood through poorly ventilated regions of the lung. The methacholine challenge revealed that gasping enhanced lung inflation and reversed the diminished Pa(O2). Moreover, beta-sympathetic function was critical to recovery. Collectively, the response profiles of these disparate models of airway challenge suggest a highly integrated balance to maintain gas exchange among the pulmonary airways and vasculature, modulated in recovery by beta-adrenoreceptors.

AN - 67407844; 15694463 AB - Primary cultures of normal human airway epithelial cells (NHBE) respond to ambient air pollution particulate matter (PM) by increased production of the cytokine IL-8, and the induction of several oxidant stress response genes. Components of ambient air PM responsible for stimulating epithelial cells have not been conclusively identified, although metal contaminants, benzo[a]pyrene and biological matter have been implicated. Stimulation of IL-8 release from NHBE with coarse (PM(2.5-10)), fine (PM2.5), and UF particle fractions has shown that the coarse particle fraction has the greatest effect on the epithelial cells as well as alveolar macrophages (AM). Since this fraction concentrates fugitive dusts and particle-associated microbial matter, it was hypothesized that NHBE may recognize PM through microbial pattern recognition receptors TLR2 and TLR4, as has been previously shown with AM. NHBE were shown to release IL-8 when exposed to a Gram-positive environmental isolate of Staphylococcus lentus, and lower levels when exposed to Gram-negative Pseudomonas spp. Comparison of TLR2 and TLR4 mRNA expression in NHBE and AM showed that NHBE express similar levels of TLR2 mRNA as the AM, but expressed very low levels of TLR4. When NHBE were stimulated with PM(2.5-10), PM2.5, and UF PM, in the presence or absence of inhibitors of TLR2 and TLR4 activation, a blocking antibody to TLR2 inhibited production of IL-8, while TLR4 antagonist E5531 or the LPS inhibitor Polymixin B had no effect. Furthermore, effects on expression of TLR2 and TLR4 mRNA, as well as the stress protein HSP70 was assessed in NHBE exposed to PM. TLR4 expression was increased in these cells while TLR2 mRNA levels were unchanged. Hsp70 was increased by PM(2.5-10) > PM2.5 > UF PM suggesting the possibility of indirect activation of TLR pathway by this endogenous TLR2/4 agonist.

We sampled the Sabine-Neches estuary, Texas, during low (November 1999) and high (May 2000) freshwater inflow and measured stable carbon isotope ratios of the dissolved inorganic and orgnaic carbon ( delta super(13)C-DIC, delta super(13)C-DOC), as well as quantifying accessory parameters (salinity, nutrients, total suspended solids, and photosynthetic pigments). Pigment analysis indicated that diatoms were the predominant phytoplankton. Data from the May 2000 sampling event exhibited conservative mixing, indicating that the system was acting as a conduit between the watershed and the Gulf of Mexico. During November, mixing was generally nonconservative indicating extensive recycling of allochthonous and autochthonous carbon sources. Our data imply that both carbon sources had similar isotope, ratios that made it impossible to unambiguously determine the dominant source supporting respiration. The nonconservative DIC concentration data indicating an autotrophic sink as well as the strong relationship between delta super(13)C-DOC and chlorophylla, suggest that in situ production was an important component of the DOC pool. We hypothesize that uncharacteristically calm wind conditions during sampling may have promoted phytoplankton settling, removing autotrophs, from the water column, but leaving behind a dissolved biogeochemical signature. Interpretation of carbon dynamics may be confounded by spatial and temporal decoupling of producers and consumers from biogeochemical indicators.

AN - 67408600; 15696091 AB - Observations of adverse effects of air pollution on public health, illustrated by the London smog events in the 1950s, led to legislation in the United States requiring development of federal, state, and local air quality management programs. The implementation of management programs has resulted in significant reductions in air pollutant emissions from stationary and mobile sources and hence their ambient concentrations and associated health risks. Evidence of benefits from improvements in air quality can be identified from studies in which rapid changes in air quality have occurred. Health risk assessment and benefits estimates also can be predictive, resulting in mean estimates of avoided mortality in excess of many thousands of cases per year as a result of implementation of air quality management programs in the United States.

These materials are variable mixtures of sand, bioclasts, carbonate mud, and carbonate cements. Intergranular carbonate material is dominated by very high-Mg calcite (VHMC), a disordered rhombic Ca-Mg carbonate in the compositional range of 24 to 44 mol% MgCO (sub 3) , as determined by X-ray diffractometry and electron microprobe analysis. Authigenic high-Mg calcite (HMC), aragonite, and pyrite are also present. Stable isotope ratios are consistent with a methane source for carbon and a seawater source for oxygen. Framboidal pyrite suggests formation under hypoxic conditions associated with microbial sulfate reduction, probably near the sediment-water interface around methane seeps. Sideritic sandstones and mudstones, also common in some of the sites studied, represent a distinct set of anoxic conditions and are likely related to the zone of methanogenesis. Bottom surveys reveal broken, abraded, and encrusted slabs of rock strewn on the seafloor. These rocks host typical "hardbottom" faunal communities rather than chemosynthetic communities, and suggest that present conditions are incompatible with the processes of carbonate authigenesis that formed the rocks. Radiocarbon analysis suggests an origin during the Holocene transgression, from biogenic rather than thermogenic methane. Occurrence of micrometer-sized particles of HMC and VHMC in both mud-supported and grain-supported textures indicates that these materials formed syndepositionally and were mixed and infiltrated into coarser sediments before lithification. Porous mud-poor sediment was cemented by larger, more distinct crystals of aragonite, HMC, and VHMC. Modified rhombic crystals with VHMC cores and HMC rims suggest that VHMC is unstable and changes to HMC rather than to dolomite. Recognition of methane-induced seafloor lithification in ancient rocks is complicated by uncertainties over the fate of unstable minerals found in Quaternary samples. Some ancient HMC and low-Mg calcite (LMC) muds and cements may have formed originally as VHMC and aragonite.

Iron, aluminum, and manganese oxides; organic matter; and phosphates, carbonates, and sulfides are important sinks for trace elements in soil-residual systems. The pH of the soil-residual system is often the most important chemical property governing trace element sorption, precipitation, solubility, and availability. Trace element phytoavailability in residual-treated soils is often estimated using soil extraction methods. However, spectroscopic studies show that sequential extraction methods may not be accurate in perturbed soil-residual systems. Plant bioassay is the best method to measure the effect of residuals on phytoavailability. Key concepts used to describe phytoavailability are (i) the salt effect, (ii) the plateau effect, and (iii) the soil-plant barrier. Metal availability in soil from metal-salt addition is greater than availability in soil from addition of metal-containing residuals. Plant metal content displays plateaus at high residual loadings corresponding to the residual's metal concentration and sorption capacity. The soil-plant barrier limits transmission of many trace elements through the food chain, although Cd (an important human health concern) can bypass the soil-plant barrier. Results from many studies that support these key concepts provide a basis of our understanding of the relationship between trace element chemistry and phytoavailability in residual-treated soils. Research is needed to (i) determine mechanisms for trace element retention of soil-residual systems, (ii) determine the effect of residuals on ecological receptors and the ability of residuals to reduce ecotoxicity in metal-contaminated soil, and (iii) predict the long-term bioavailability of trace elements in soil-residual systems.

Amended sites were seeded and a plant cover was subsequently established. A range of chemical and biological parameters were measured over time to determine if treatment was sufficient to restore ecosystem function. An uncontaminated upstream control (UUC), a contaminated vegetated area (CVA), and soils collected from the tailings deposits before amendment addition were used for comparison. Standard soil extracts showed decreases in extractable Pb, Zn, and Cd in the amended soils. Increased CO (sub 2) evolution, reduced N (sub 2) O, and elevated NO (sub 3) (super -) in the amended tailings indicated an active microbial community. Levels of CO (sub 2) and NO (sub 3) (super -) were elevated in comparison with the CVA and UUC. Ryegrass (Lolium perenne L.) and earthworm (Eisenia foetida) survival and metal uptake values were similar in amended tailings to a laboratory control soil. Ryegrass and worms in unamended tailings died. Field plant diversity was lower in amended areas than in CVA or UUC, with a higher percentage of the vegetative cover consisting of grasses. Small mammal analysis showed a low potential for elevated body Cd and Pb in the amended tailings. A re-entrainment study using fathead minnows (Pimephales promelas) showed no danger for resuspended amended tailings, as survival of fish was similar to the laboratory control. Data suggest that ecosystem function has been restored to the amended tailings, but that these systems are not yet in equilibrium.

Nonhazardous wastes include a vast array of materials, including manures, biosolids, composts, wastewater effluents, food-processing wastes, industrial by-products; these are collectively referred to herein as residuals. Because of economic restraints and environmental concerns about land-filling and incineration, interest in land application continues to grow. A major lesson that has been learned, however, is that the traditional definition of land application that emphasizes applying residuals to land in a manner that protects human and animal health, safeguards soil and water resources, and maintains long-term ecosystem quality is incomplete unless the earning of public trust in the practices is included. This overview provides an introduction to a subset of papers and posters presented at the conference, "Sustainable Land Application," held in Orlando, FL, in January 2004. The USEPA, USDA, and multiple national and state organizations with interest in, and/or responsibilities for, ensuring the sustainability of the practice sponsored the conference. The overriding conference objectives were to highlight significant developments in land treatment theory and practice, and to identify future research needs to address critical gaps in the knowledge base that must be addressed to ensure sustainable land application of residuals.

We investigated the relation between maternal sport fish meals and risk of major birth defects among infants born to members of the New York State (NYS) Angler Cohort between 1986 and 1991 (n=2237 births). Birth defects (n=125 cases) were ascertained from both newborn medical records and the NYS Congenital Malformations Registry. For sport fish meals eaten during pregnancy, the odds ratio (OR) for all major malformations combined was slightly elevated for ==2 meals/month (OR=1.51, CI=0.74, 3.09), with no meals during pregnancy as the reference category. Higher ORs were consistently observed among male offspring compared with females. For >=2 meals/month, the risk for males was significantly elevated (males: OR=3.01, CI: 1.2, 7.5; females: OR=0.73, CI: 0.2, 2.4). Exposure during pregnancy and effect modification by infants sex could be important considerations for future studies of birth outcomes associated with endocrine disruptors.

Measurements by this method were compared with counts of Enterococcus colony-forming units (CFU) determined by Method 1600 membrane filter (MF) analysis using mEI agar. The QPCR method had an estimated 95% confidence, minimum detection limit of 27 Enterococcus cells per sample in analyses of undiluted DNA extracts and quantitative analyses of multiple lake water samples, spiked with known numbers of these organisms, gave geometric mean results that were highly consistent with the spike levels. At both beaches, the geometric means of ambient Enterococcus concentrations in water samples, determined from multiple collection points during each sampling visit, showed approximately lognormal distributions over the study period using both QPCR and MF analyses. These geometric means ranged from 10 to 8548 cells by QPCR analysis and 1-2499 CFU by MF culture analysis in Lake Michigan, (N=56), and from 8 to 8695 cells by QPCR and 3-1941 CFU by MF culture in Lake Erie, (N=47), . Regression analysis of these results showed a significant positive correlation between the two methods with an overall correlation coefficient (r) of 0.68.

AN - 17866669; 6231189 AB - The germinable soil seed bank of a tropical eucalypt savanna of north-eastern Australia was found to be dominated by grasses and forbs, with seed bank density ranging from 58 to 792 seeds per square metre, from a total of 53 species. Late dry season fires and the fire-related cues, heat shock and smoke, broke the seed dormancy of a range of tropical savanna species. Heat shock promoted the germination of the species groups natives, exotics, subshrubs, ephemeral and twining perennial forbs, and the common species Indigofera hirsuta, Pycnospora lutescens and Triumfetta rhomboidea. Exposure to smoke at ambient temperature promoted germination from the soil seed bank of the species groups combined natives, upright perennial forbs and grasses, as well as the common grasses Digitaria breviglumis and Heteropogon triticeus. The germinable soil seed bank varied seasonally, increasing from the mid wet season (February) and early dry season (May) to a maximum in the late dry season (October). The effect of recent fire history on soil seed bank dynamics was limited to the immediate release of some seed from dormancy; a reduction in seed densities of subshrubs and monocots, other than grasses, in recently burnt savanna; and enhanced seed density of the ephemeral I. hirsuta in the year following fire. The seed banks of most savanna species were replenished in the year following burning.

Pathology endpoints are the central response around which human health risk assessment is frequently determined; therefore, it is important that the general toxicology community understand current concepts and nomenclature of toxicologic pathology. Toxicologic pathology encompasses the study of changes in tissue morphology that help define the risk of exposure to xenobiotics. Toxicologic pathology is a discipline that has changed and adapted over time including methods of analysis and nomenclature of lesions. As risk assessments are updated for chemicals in commerce, frequently the older literature must be reviewed and reevaluated. When interpreting pathology data from animal studies, it is important to consider the biological significance of a lesion as well as its relationship to the ultimate adverse health effect. Assessing the potential for a chemical to cause harm to humans must include the examination of the entire pathology database in context of the study design, the mode of action of the chemical of concern, and using the most current interpretation of a lesion to determine the significance for human health effects of a particular tissue response.

This toxic, red-tide dinoflagellate grew faster with higher temperatures, up to a maximum of approximately 1 division per day at 31 degree C. Salinities above 15 psu had a lesser effect on growth rate, as might be expected for an estuarine species. Growth rates of cultures exposed to natural light and temperature fluctuations were comparable to laboratory cultures. The minimum N cell quota suggested that high N flux would be required to support bloom development. A literature survey of documented A. monilatum blooms indicated that within US waters, blooms occur in July-September in nearshore or estuarine regions of the Gulf of Mexico and the Florida Atlantic coast. Temperature and salinity measured during blooms correspond to the optimal growth conditions of the laboratory cultures. Nevertheless, the occurrence of A. monilatum blooms is sporadic compared to the occurrence of seemingly optimal growth conditions. Laboratory growth experiments predict when blooms of this species are unlikely due to low growth rates, but so far cannot predict individual blooms.

Despite its small contribution to PBDE global production and usage, BDE 47 is the major congener found in environmental samples and human tissue. No human data are currently available regarding the toxicokinetics of BDE 47 either as an individual congener or in the commercial mixture. Because previous studies have suggested potential toxicokinetic differences between rodent species, this study was conducted in an effort to fully characterize absorption, distribution, and excretion parameters following a single dose with respect to dose, time, and route of exposure in female C57BL/6 mice. Over 80% of the administered dose was absorbed after oral or intratracheal administration, whereas [approx]62% was absorbed when the dose was applied dermally. Disposition was dictated by lipophilicity as adipose and skin were major depot tissues. BDE 47 was rapidly excreted in the urine and feces. Of particular interest was the amount of parent compound found in the urine, which was a major factor in determining an initial whole-body half life of 1.5 days after a single oral exposure. Elimination, both whole-body and from individual tissues, was biphasic. Initial half-lives were 1- 3 days, whereas terminal half-lives were much longer, suggesting the potential for bioaccumulation. This toxicokinetic behavior has important implications for extrapolation of toxicological studies to the assessment of health risk in humans.

In the present study, propiconazole was examined for its effects on the expression of hepatic cytochrome P450 genes and on the activities of P450 enzymes in male Sprague-Dawley rats and male CD-1 mice. Rats and mice were administered propiconazole by gavage daily for 14 days at doses of 10, 75, and 150 mg/kg body weight/day. Quantitative real time RT-PCR assays of rat hepatic RNA samples from animals treated at the 150 mg/kg body weight/day dose revealed significant mRNA overexpression of the following genes compared to control: CYP1A2 (1.62-fold), CYP2B1 (10.8-fold), CYP3A1/CYP3A23 (2.78-fold), and CYP3A2 (1.84-fold). In mouse liver, propiconazole produced mRNA overexpression of Cyp2b10 (2.39-fold) and Cyp3a11 (5.19-fold). mRNA expression of CYP1A1 was not detected in liver tissues from treated or controls animals from either species. Propiconazole significantly induced both pentoxyresorufin O-dealkylation (PROD) and methoxyresorufin O- dealkylation (MROD) activities in both rat and mouse liver at the 150 mg/kg body weight/day and 75 mg/kg body weight/day doses. In summary, these results indicated that propiconazole induced CYP1A2 in rat liver and CYP2B and CYP3A families of isoforms in rat and mouse liver.

AN - 17317278; 6157048 AB - Since the 1990s, the Philippines has begun to adopt the tenets of sustainable forest management (SFM) with respect to the use and management of its forests. Consequently, government policies affecting the forestry sector have been evolving, to reflect the new forest management paradigm. Although the country's forest policies have been mostly economic-oriented, such policies are now directed at multiple goals including social and environmental goals, either through deliberate considerations or on an ad hoc basis. Most of the policies affecting the forestry sector have been implemented since the 1970s. Such policies include the partial ban on log exports as well as trade policies directed at the exportation of logs and lumber and the importation of pulp. In the 1970s, the forestry sector was notably 1 of the top 10 sectors with respect to export earnings, mainly from the exportation of raw logs. For a country concerned with addressing poverty and deforestation problems, these socio-economic contributions seemed invaluable. However, the negative effects of logging on the forest resource overshadowed the economic benefits derived from such activities. The forest resource base was greatly reduced; consequently, the government implemented a log export ban policy aimed at mitigating deforestation problems. This export ban was also directed at improving the efficiency and competitiveness of the wood processing industry. With the global adoption of SFM and the mounting pressure from lending institutions for policy reforms as instruments of growth and development, the issue is revisited to examine whether these Philippine government policies promote or discourage such multiple goals. This article discusses the repercussions of the log export ban and trade policies on the Philippine government's multiple targets for the economy and for the environment. Using an aggregation of the global trade analysis project model, a computable general equilibrium model, the impacts of these resources and trade policies are analysed.

These types of exposures can be expected to result in blood lead concentrations that vary on a temporal scale with the intermittent exposure pattern. Prediction of short-term (or seasonal) blood lead concentrations arising from highly variable intermittent exposures requires a model that can reliably simulate lead exposures and biokinetics on a temporal scale that matches that of the exposure events of interest. If exposure model averaging times (EMATs) of the model exceed the shortest exposure duration that characterizes the intermittent exposure, uncertainties will be introduced into risk estimates because the exposure concentration used as input to the model must be time averaged to account for the intermittent nature of the exposure. We have used simulation as a means of determining the potential magnitude of these uncertainties. Simulations using models having various EMATs have allowed exploration of the strengths and weaknesses of various approaches to time averaging of exposures and impact on risk estimates associated with intermittent exposures to lead in soil. The International Commission of Radiological Protection (ICRP) model of lead pharmacokinetics in humans simulates lead intakes that can vary in intensity over time spans as small as one day, allowing for the simulation of intermittent exposures to lead as a series of discrete daily exposure events. The ICRP model was used to compare the outcomes (blood lead concentration) of various time-averaging adjustments for approximating the time-averaged intake of lead associated with various intermittent exposure patterns. Results of these analyses suggest that standard approaches to time averaging (e.g., U.S. EPA) super(()) that estimate the long-term daily exposure concentration can, in some cases, result in substantial underprediction of short-term variations in blood lead concentrations when used in models that operate with EMATs exceeding the shortest exposure duration that characterizes the intermittent exposure. Alternative time-averaging approaches recommended for use in lead risk assessment super(()) more reliably predict short-term periodic (e.g., seasonal) elevations in blood lead concentration that might result from intermittent exposures. In general, risk estimates will be improved by simulation on shorter time scales that more closely approximate the actual temporal dynamics of the exposure.

This article traces the successful networking of demonstrations at a landfill in New Jersey and the subsequent design of the CARIBELATE project in the Municipality of Carolina, Puerto Rico. The institutional model developed for the Puerto Rico facility has brought together an unlikely combination of stakeholders. Those from the private sector, here called industrial partners, are paired with academic researchers to optimize products for local markets. The basic technology system demonstrated in New Jersey and to be replicated in Puerto Rico removes harmful contaminants from landfill gas and in so doing produces a variety of useful products. A portion of the landfill gas is utilized for micro-turbine electricity generation and for heating a demonstration greenhouse that houses aquaculture coupled with hydroponic crop production, where aquaculture effluents are recycled as plant nutrients. A strict protocol to verify emission reduction is imposed on all the demonstrations at the CARIBELATE project. Although greenhouse gas credit verification is not the prime mission, it is suggested that the credits verified from these demonstrations are of high quality, and can serve as an excellent training platform. CARIBELATE is conceived to be operated at the municipal level and contribute to income generation and economic development. The continuing networking of stakeholders from the public and private sectors offers some potential guidance for replicating this design in the developing world.

Although their acute neurotoxicity to adults has been well characterized, information regarding the potential developmental neurotoxicity of this class of compounds is limited. There is a large age dependence to the acute toxicity of pyrethroids in which neonatal rats are at least an order of magnitude more sensitive than adults to two pyrethroids. There is no information on age-dependent toxicity for most pyrethroids. In the present review we examine the scientific data related to potential for age-dependent and developmental neurotoxicity of pyrethroids. As a basis for understanding this neurotoxicity, we discuss the heterogeneity and ontogeny of voltage-sensitive sodium channels, a primary neuronal target of pyrethroids. We also summarize 22 studies of the developmental neurotoxicity of pyrethroids and review the strengths and limitations of these studies. These studies examined numerous end points, with changes in motor activity and muscarinic acetylcholine receptor density the most common. Many of the developmental neurotoxicity studies suffer from inadequate study design, problematic statistical analyses, use of formulated products, and/or inadequate controls. These factors confound interpretation of results. To better understand the potential for developmental exposure to pyrethroids to cause neurotoxicity, additional, well-designed and well-executed developmental neurotoxicity studies are needed. These studies should employ state-of-the-science methods to promote a greater understanding of the mode of action of pyrethroids in the developing nervous system.

No adsorbate was present on the GAC so physicochemical effects from chemically aggressive regeneration could be distinguished from the potential effects of accumulation of reaction byproducts. Fifteen sequential oxidation treatments with hydrogen peroxide (H sub(2)O sub(2)) and fifteen sequential reduction/oxidation treatments with hydroxylamine and H sub(2)O sub(2) on Fe-amended GAC were evaluated. The GAC Iodine number, N sub(2) Brunauer-Emmett-Teller surface area, microporosity, and total porosity declined with sequential treatments, but meso- and macroporosity essentially remained unchanged. Similar changes in Iodine number, surface area, and pore volume distribution suggest that the effects of treatment are functionally dependent on oxidation and independent of hydroxylamine reduction. An inverse relationship was established between the number of chemical treatments and contaminant (methyl tert-butyl ether, 2-chlorophenol, trichloroethylene) adsorption. Loss in sorptive capacity was attributed to the combined and undifferentiated effects of reductions in microporosity and surface area, alterations in surface chemistry (overabundance of surface oxides), and to a lesser degree, micropore blockage by iron oxides.

Genetic algorithms allow solution of more complex nonlinear problems than traditional gradient-based approaches, but they are more computationally intensive. One way to improve performance is through inclusion of local search, creating a hybrid genetic algorithm (HGA). This paper presents a new self-adaptive HGA (SAHGA) and compares its performance to a nonadaptive hybrid genetic algorithm (NAHGA) and the simple genetic algorithm (SGA) on a groundwater remediation problem. Of the two hybrid algorithms, SAHGA is shown to be far more robust than NAHGA, providing fast convergence across a broad range of parameter settings. For the test problem, SAHGA needs 75% fewer function evaluations than SGA, even with an inefficient local search method. These findings demonstrate that SAHGA has substantial promise for enabling solution of larger-scale problems than was previously possible.

Two study sites were located, along an elevational transect, in the Oregon Cascade Mountains in mature (>100 years old), closed-canopy Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands growing on soils with differing resource levels. The low resource site (LRS) had lower soil N (0.15% total N) and lower available water capacity (83mm) than the high resource site (HRS), where soil N was 0.25% total N and available water capacity was 145mm. Minirhizotron tubes were installed at each site during August 1994. To allow time for recovery from tube installation, the first root images were collected in late fall 1995 and then at pound sterling week intervals thereafter, except when snow prevented sample collection at the LRS. Root data from soil cores collected near the minirhizotron tubes were used to convert the minirhizotron data to the units of gm super(-) super(2) (to a depth of 60cm). Tree bole growth, at the HRS, was about twice that at the LRS, while fine root biomass, at the HRS, was only a third of that at the LRS. Seasonally, fine root production started before the onset of bole growth. Fine root standing crop, production, and mortality were consistently higher at the LRS than at the HRS. These findings support the concept that plants allocate more C to fine roots when soil resources are low. Our estimates of fine root production and mortality tend to be larger than previous reports for Douglas-fir stands. These differences can be attributed, in part, to the failure of the previous studies to account for fine root production and mortality between sampling events.

AN - 67342987; 15631514 AB - An acid phosphatase from the aquatic plant Spirodela oligorrhiza (duckweed) was isolated by fast protein liquid chromatography and partially characterized. The enzyme was purified 1871-fold with a total yield of 40%. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of the pure acid phosphatase resolved a single protein band that migrated to approximately 60 kDa. Nondenaturing SDS-PAGE electrophoresis revealed a single protein band around 120 kDa after staining with Coomassie Brilliant blue. Quantitative gel filtration chromatography estimated a native molecular mass of this enzyme to be 120 kDa. Thus, this acid phosphatase likely functions as a homodimer, consisting of two similar 60 kDa subunits. An electrophoretic technique using the flourogenic substrate 4-methylumbelliferyl phosphate enabled visualization of an acid phosphatase activity that corresponded to the protein band at 120 kDa on a nondenaturing PAGE gel. It was determined that the acid phosphatase had a pH optimum of 6.0 at 25 degrees C. The enzyme activity appeared to be stable over a broad range of temperatures (10-40 degrees C) and in the presence of the metals Zn2+, Mn2+, and Mg2+ as well as the chelating agents ethylenedinitrilotetraacetic acid and ethylene glycol tetraacetic acid. It was shown that this acid phosphatase could hydrolyze a variety of physiological organophosphate compounds including beta-glycerophosphate, phosphoserine, adenosine triphosphate, adenosine diphosphate, adenosine monphosphate, and pyrophosphate. Furthermore, analysis using capillary electrophoresis demonstrated that this hydrolytic enzyme could transform a wide array of organophosphate pesticides including S-2-ethylthioethyl O,O-dimethylphosphorothioate (demeton-S-methyl); S-1,2-bis(ethoxycarbonyl)ethyl O,O-dimethylphosphorodithioate (malathion); O,O-dimethyl O-4-nitrophenyl (paraoxon); O,O,O,O-tetraethyldithiopyrophosphate (sulfatep); O-2-chloro-4-nitrophenyl O,O-dimethylphosphorothioate (dicapthon); and 2,2-dichlorovinyl dimethylphosphate (dichlorvos).

AN - 70186368; 16961006 AB - Increasing toxicologic and epidemiologic evidence suggests that pesticides and other environmental exposures are associated with idiopathic Parkinson's disease. Using a case-control study, the authors examined the impact of farming, pesticide use, rural residence, and well water use (including critical periods of childhood exposure) on the risk of Parkinson's disease. After adjustment for confounding, > or = 40 years of well-water exposure (compared to no well water use) was associated with an increased risk of Parkinson's disease (OR = 7.1; 95% CI: 2.3-22.1). The authors found an increased risk of Parkinson's disease (OR = 2.1; 95% Cl: 0.7-6.4) for well water use during the first 20 years of life (compared with <20 years of exposure) and saw some suggestion of an exposure-response relationship with increasing childhood exposure. Farming and pesticide use (occupational or residential) was not associated with Parkinson's disease but exposure assessment limitations warrant further investigation.

AN - 70182954; 17192035 AB - A biomarker can be broadly defined as any biological index capable of being measured, which is associated with or indicative of a defined biological endpoint such as a developmental or disease stage. Identification and verification of anatomical, endocrine, cellular and molecular biomarkers is crucial for successful clinical diagnosis and treatment of toxicity and disease, as well as basic toxicological, epidemiological and other research. Various biomarkers of reproductive development and health have been identified, including those associated with pubertal development, adult reproductive health and pregnancy outcome. Herein we discuss those in situ biomarkers which have been more closely associated with toxicant action on the reproductive system. Biomarkers of toxicant exposure and susceptibility are addressed, but the majority of the review focuses on those biomarkers which may prove useful for determining current pathophysiological status or predicting future adverse outcomes. In males these are primarily associated with altered spermatogenesis and sperm parameters, and in females with altered endocrine function. We conclude that although few robust in situ biomarkers are currently available which are specific for toxicant exposure, susceptibility or effect in reproductive systems, there is expectation that post-genomic technologies offer a new paradigm for identifying and verifying such biomarkers as may exist.

AN - 69054137; 16392172 AB - Ammonium perchlorate (AP) and sodium chlorate (SC) have been detected in public drinking water supplies in many parts of the United States. These chemicals cause perturbations in pituitary-thyroid homeostasis in animals by competitively inhibiting iodide uptake, thus hindering the synthesis of thyroglobulin and reducing circulating T(4) (thyroxine). Little is known about the short-term exposure effects of mixtures of perchlorate and chlorate. The present study investigated the potential for the response to a mixture of these chemicals on the pituitary-thyroid axis in rats to be greater than that induced by the individual chemicals. Adult male F-344 rats were exposed, via their drinking water, to the nominal concentrations of 0.1, 1.0, 10 mg/L AP or 10, 100, 1000 mg/L SC and their mixtures for 7 days. Serum T(4) levels were significantly (p < 0.05) reduced in rats following exposure to the mixtures, but not after exposure to the individual chemicals. Serum T(3) (triiodothyronine) was not altered by treatment and TSH (thyroid stimulating hormone) was only increased after the high-dose chlorate treatment. Histological examination of the thyroid gland showed colloid depletion and hypertrophy of follicular epithelial cells in high-dose single chemical and all mixture-treated rats, while hyperplasia was observed only in some of the rats treated with mixtures (AP 10 + SC 100, AP 0.1 + SC 1000, and AP 10 + SC 1000 mg/L). These data suggest that short-term exposure to the mixture of AP and SC enhances the effect of either chemical alone on the pituitary-thyroid axis in rats.

AN - 68807308; 16291527 AB - 3-Chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone, better known by its historical name 'mutagen X' or MX, is a chlorination disinfection byproduct that forms from the reaction of chlorine and humic acids in raw water. MX has been measured in drinking water samples in several countries at levels that ranged from non-detectable to 310 ng/L. Although the concentration of MX in drinking water is typically 100- to 1000-fold lower than other common chlorinated by-products of concern (e.g., trihalomethanes), some have hypothesized that MX might play a role in the increased cancer risks that have been associated with the consumption of chlorinated water. This hypothesis is based on observations that MX, in some test systems, is extremely potent relative to trihalomethanes in inducing DNA damage and altering pathways involved in cell growth, and that in some epidemiological studies increased cancer rates are associated with the bacterial mutagenicity of disinfected water of which MX contributes a significant portion. MX also appears to be more potent than other chlorination by-products in causing cancer in animals. This article reviews the available evidence on the carcinogenicity of MX. MX induced cancer at multiple sites in male and female rats, acted as a tumor initiator and promoter, enhanced tumor yields in genetically modified rodents, induced a myriad of genotoxic effects in numerous in vitro and in vivo test systems, and was a potent inhibitor of gap junction intercellular communication. Although the precise mechanism of MX-induced DNA damage is not known, MX is able to cause DNA damage through an unusual mechanism of ionizing DNA bases due to its extremely high reductive potential. MX may also cause mutations through DNA adduction. This article develops a mean cancer potency estimate for MX of 2.3 (mg/kg-d)(-1) and an upper 95% percentile estimate of 4.5 (mg/kg-d)(-1), and examines the potential health risks posed by this chlorination contaminant in drinking water. A discussion of additional data that would be desirable to better characterize the risks posed by MX and other halogenated hydroxyfuranones follows. JF - Journal of environmental science and health.

AN - 68727674; 16249963 AB - Visual disruption in patients diagnosed with epilepsy may be attributable to either the disease itself or to the anti-epileptic drugs prescribed to control the seizures. Effects on visual function may be due to perturbations of the GABAergic neurotransmitter system, since deficits in GABAergic cortical interneurons have been hypothesized to underlie some forms of epilepsy, some anti-epileptic medications increase cortical GABA levels, and GABAergic neural circuitry plays an important role in mediating the responses of cells in the visual cortex and retina. This paper characterizes the effects of epilepsy and epilepsy medications on the visual evoked response to patterned stimuli. Steady-state visual evoked potentials (VEP) evoked by onset-offset modulation of high-contrast sine-wave stimuli were measured in 24 control and 54 epileptic patients. Comparisons of VEP spectral amplitude as a function of spatial frequency were made between controls, complex partial, and generalized epilepsy groups. The effects of the GABA-active medication valproate were compared to those of carbamezepine. The amplitude of the fundamental (F1) component of the VEP was found to be sensitive to epilepsy type. Test subjects with generalized epilepsy had F1 spatial frequency-amplitude functions with peaks shifted to lower spatial frequencies relative to controls and test subjects with complex partial epilepsy. This shift may be due to reduced intracortical inhibition in the subjects with generalized epilepsy. The second harmonic component (F2) response was sensitive to medication effects. Complex partial epilepsy patients on VPA therapies showed reduced F2 response amplitude across spatial frequencies, consistent with previous findings that showed the F2 response is sensitive to GABA-ergic effects on transient components of the VEP.

AN - 68585715; 16162146 AB - To compare the populations of 81 mould species in homes in the USA and UK using mould-specific quantitative polymerase chain reaction (MSQPCR) technology. Dust samples were obtained from randomly selected homes in the UK (n=11). The mould populations in British homes were compared with those found in typical homes (no visible mould) in the USA (in the state of Ohio, n=45). Only 13 of 81 species screened showed significantly different concentrations in these two sets of home. Although only a small survey, the results suggest that typical mould profiles in the USA (Ohio) and British homes are very similar. Analysis of 26 mould indicator species revealed that the British homes fell into two clusters, tentatively identified as 'atypical' and 'typical' mould conditions. MSQPCR analysis of dust samples can provide an objective measure of indoor moulds which could lead to better management of their health effects.

AN - 68442464; 16078642 AB - Some strains of Penicillium chrysogenum produce a proteinaceous hemolysin, chrysolysinTM, when incubated on sheep's blood agar at 37 degrees C but not at 23 degrees C. However, 92% (11/12) of the indoor air isolates produced hemolysis but only 43% (3/7) of the non-indoor air isolates did so. Chrysolysin is an aggregating protein composed of approximately 2kDa monomers, contains one cysteine amino acid, and has an isoelectric point of 4.85. Treatment of murine macrophage cell line RAW 264.7 with purified chrysolysin caused statistically significant (T-test, p < 0.05) increased production of macrophage inflammatory protein-2 (MIP-2) in a dose dependent manner after 6 h treatment.

AN - 68440854; 16076769 AB - Thyroid proliferative lesions are rather common in bony fishes but disagreement exists in the fish pathology community concerning diagnostic criteria for hyperplastic versus neoplastic lesions. To simplify the diagnosis of proliferative thyroid lesions and to reduce confusion regarding lesion interpretation, we propose specific criteria for distinguishing hyperplastic from neoplastic lesions. Development of these criteria was based on the examination of a large series of proliferative lesions from Japanese medaka (Oryzias latipes), lesions from other small fish species, and a reexamination of the 97 cases of proliferative thyroid lesions from bony fishes deposited in the Registry of Tumors in Lower Animals. Specific diagnostic criteria are provided for all lesion categories including follicular cell hyperplasia (simple, nodular, or ectopic), adenoma (papillary or solid), and carcinoma (well- or poorly differentiated). These criteria should assist fish pathologists in describing and categorizing naturally occurring proliferative lesions from wild fishes, lesions that develop in laboratory fishes due to suboptimal culture practices or water quality, those in fishes used in toxicological assays, and captive aquarium fishes.

AN - 68064132; 16036858 AB - Formaldehyde is cytotoxic and carcinogenic to the rat nasal respiratory epithelium inducing tumors after 12 months. Glutaraldehyde is also cytotoxic but is not carcinogenic to nasal epithelium even after 24 months. Both aldehydes induce similar acute and subchronic histopathology that is characterized by inflammation, hyperplasia, and squamous metaplasia. Because early aldehyde-induced lesions are microscopically similar, we investigated whether transcriptional patterns using cDNA technology could explain the different cancer outcomes. Treatments included 1-, 5-, or 28-day exposure by nasal instillation of formaldehyde solution (400 mM) or glutaraldehyde solution (20 mM). Animals were euthanized and the nasal respiratory epithelium removed for gene expression analysis and a subset of rats treated for 28 days was processed for microscopic examination. RNA was isolated and processed for expression assessment using Clontech Atlas Toxicology II Arrays. Both aldehydes induced hyperplasia, squamous metaplasia, and inflammatory infiltrates with scattered apoptotic bodies in the epithelium covering luminal surfaces of the nasoturbinate, maxilloturbinate, and nasal septum. A subset of 80 genes that were the most variant between the treated and control included the functional categories of DNA repair and apoptosis. Hierarchical clustering discriminated chemical treatment effects after 5 days of exposure, with 6 clusters of genes distinguishing formaldehyde from glutaraldehyde. These data suggest that although both aldehydes induced similar short-term cellular phenotypes, gene expression could distinguish glutaraldehyde from formaldehyde. The gene expression patterns suggest that glutaraldehyde's lack of carcinogenicity may be due to its greater toxicity from lack of DNA-repair, greater mitochondrial damage, and increased apoptosis.

AN - 67966436; 15976457 AB - Information regarding the deposition patterns of inhaled particles has important implications to the fields of medicine and risk assessment. The former concerns the targeted delivery of inhaled pharmacological drugs (aerosol therapy); the latter concerns the risk assessment of inhaled air pollutants (inhalation toxicology). It is well documented in the literature that the behavior and fate of inhaled particles may be formulated using three families of variables: respiratory system morphologies, aerosol characteristics, and ventilatory parameters. It is straightforward to propose that the seminal role is played by morphology per se because the structures of individual airways and their spatial orientations within lungs affect the motion of air and the trajectories of transported particles. In previous efforts, we have developed original algorithms to describe airway networks within lungs and employed them as templates to interpret the results of single photon emission computed tomography (SPECTs) studies. In this work, we have advanced the process of mathematical modeling and computer simulations to produce three-dimensional (3D) images. We have tested the new in silico model by studying two different branching concepts: an inclusive (all airways present) system and a single "typical" pathway system. When viewed with the glasses supplied with this volume, the 3D nature of airway branching networks within lungs as displayed via our original computer graphics software is clear. We submit that the new technology will have numerous and seminal functions in future medical and toxicological regimens, the most fundamental being the creation of a platform to view natural 3D structures in vivo with related biological processes (e.g., disposition of inhaled pharmaceuticals).

The most important scope of these investigations was to study the performance of these detectors directly in the field. To this end, two different types of radon monitors mentioned above have been exposed simultaneously in 100 school rooms within the Italian region Friuli Venezia Giulia.

AN - 67505851; 15757709 AB - Adaptive management is the pathway to effective conservation, use and management of Australia's coastal catchments and waterways. While the concepts of adaptive management are not new, applications involving both assessment and management responses are indeed limited at the national and regional scales. This paper outlines the components of a systematic framework for linking scientific knowledge, existing tools, planning approaches and participatory processes to achieve healthy regional partnerships between community, industry, government agencies and science providers to overcome institutional barriers and uncoordinated monitoring. The framework developed by the Coastal CRC (www.coastal.crc.org.au/amf/amf/_index.htm) is hierarchical in the way it displays information to allow associated frameworks to be integrated, and represents a construct in which processes, information, decision tools and outcomes are brought together in a structured and transparent way for adaptive catchment and coastal management. This paper proposes how an adaptive management approach could be used to benefit the implementation of the Reef Water Quality Protection Plan (RWQPP).

AN - 67505567; 15757710 AB - The Australian and New Zealand Guidelines for Fresh and Marine Water Quality (ANZECC Guidelines) provide default national guideline values for a wide range of indicators of relevance to the protection of the ecological condition of natural waters. However, the ANZECC Guidelines also place a strong emphasis on the need to develop more locally relevant guidelines. Using a structured framework, this paper explores indicators and regional data sets that can be used to develop more locally relevant guidelines for the Great Barrier Reef World Heritage Area (GBRWHA). The paper focuses on the water quality impacts of adjacent catchments on the GBRWHA with the key stressors addressed being nutrients, sediments and agricultural chemicals. Indicators relevant to these stressors are discussed including both physico-chemical pressure indicators and biological condition indicators. Where adequate data sets are available, guideline values are proposed. Generally, data were much more readily available for physico-chemical pressure indicators than for biological condition indicators. Specifically, guideline values are proposed for the major nutrients nitrogen (N) and phosphorus (P) and for chlorophyll-a. More limited guidelines are proposed for sediment related indicators. For most agricultural chemicals, the ANZECC Guidelines are likely to remain the default of choice for some time but it is noted that there is data in the literature that could be used to develop more locally relevant guidelines.

AN - 67504641; 15757711 AB - The Queensland Environmental Protection Agency monitored water quality at 133 sites in North Queensland waterways between Cooktown and Bundaburg from 1992 to 2001. Condition of the waterways was rated by comparing recent data with the Queensland Water Quality Guidelines. Long-term trends were analysed using a censored regression technique that incorporates the effects of flow, temperature, seasonality and allows for long-term non-linear trends. Many sites were in good condition; those in poor condition were usually impacted by point source discharges; those in moderate condition were usually impacted by agricultural land use. There were no consistent long-term trends across the whole region. Recommendations for future programs include incorporating pressure indicators, ensuring high standards of quality assurance, including covariates such as rainfall in trend assessment and continuing programs over more than 10 years to allow detection of trends due to changes in land-use.

AN - 67504540; 15757713 AB - We present an overview of a portable underway water quality monitoring system (RUM-Rapid Underway Monitoring), developed by integrating several off-the-shelf water quality instruments to provide rapid, comprehensive, and spatially referenced 'snapshots' of water quality conditions. We demonstrate the utility of the system from studies in the Northern Great Barrier Reef (Daintree River) and the Moreton Bay region. The Brisbane dataset highlights RUM's utility in characterising plumes as well as its ability to identify the smaller scale structure of large areas. RUM is shown to be particularly useful when measuring indicators with large small-scale variability such as turbidity and chlorophyll-a. Additionally, the Daintree dataset shows the ability to integrate other technologies, resulting in a more comprehensive analysis, whilst sampling offshore highlights some of the analytical issues required for sampling low concentration data. RUM is a low cost, highly flexible solution that can be modified for use in any water type, on most vessels and is only limited by the available monitoring technologies.

AN - 67399713; 15686870 AB - A byproduct of drinking water disinfection, bromochloroacetic acid (BCA), acts as a reproductive toxicant in rats. To determine if BCA produces similar reproductive toxicity in mice, juvenile and adult C57BL/6 males were exposed to 0, 8, 24, 72 or 216 mg/kg of BCA once daily for 14 days. Five of 12 animals from each dose-group were sacrificed at the end of dosing, and testes, epididymes, and seminal vesicles harvested and weighed. Seven mice from each dose-group (including juvenile-exposed mice, following a 14-week maturation period) were used in a 40-day sequential breeding assay to determine if BCA targets a particular phase of spermatogenesis. No significant effects were observed in mice exposed to BCA as juveniles, and there were no effects on fertility by 14 weeks after dosing. However, effects were observed in adult-exposed mice over the first 10 days after BCA exposure: mean number of litters/male, percentage of litters/female bred, and total number of fetuses/male were all reduced by 72 and 216 mg/kg BCA. These results in adult mice indicate BCA disrupted differentiation of spermatids during dosing and the first 10 days of mating, and are consistent with the spermatid retention and atypical residual bodies observed in animals exposed to 72 and 216 mg/kg BCA. To investigate mechanisms involved, we utilized cDNA microarrays containing 950 testis-expressed genes to profile gene expression from Control and BCA-treated mice. Statistical analyses of microarray results identified 40 well-characterized genes differentially expressed in a dose responsive manner as a result of BCA exposure. Microarray results were supplemented with quantitative real-time PCR and Westerns for several genes and proteins. The 40 genes whose expression was altered by BCA are involved in numerous biological processes including: cell communication and adhesion, cell cycle and cell proliferation, metabolism, signal transduction, stress response, and spermatogenesis and male fertility. Modulated expression of these genes, particularly the 15 expressed in Sertoli cells and spermatids, offers new insights into potential mechanisms of BCA toxicity in the mouse testis.

AN - 67398463; 15686874 AB - Reproductive toxicogenomic studies generate large amounts of toxicological and genomic data. On the toxicology side, a substantial quantity of data accumulates from conventional endpoints such as histology, reproductive physiology and biochemistry. The largest source of genomics data is DNA microarrays, which generate enormous amounts of information in the course of profiling gene expression. Thus, data storage and management become essential and require a more sophisticated system than lab notebooks and electronic spreadsheets. We developed a database for tracking toxicogenomic samples and procedures (TSP 1.0) for our reproductive studies based on the MIAME-Tox guidelines and relational database theory. This database stores the various types of data from both toxicological and genomic assays in a hierarchical fashion. The user-friendly interface provides easy procedures for researchers to add, edit, save, delete, and navigate different records. Finally, TSP facilitates exporting microarray data into public databases. JF - Reproductive toxicology (Elmsford, N.Y.)

AN - 67398056; 15686871 AB - Vinclozolin and procymidone are antiandrogens that are thought to share a common androgen receptor (AR) mediated mechanism of action. This assessment is based primarily on morphological, AR binding, and in vitro transcriptional activation studies. Studies designed to evaluate the gene expression profiles induced by these compounds have the potential to provide further information to test this hypothesis. We have used targeted gene arrays to examine gene expression in the ventral prostate (VP) of 100-day old Sprague Dawley male rats exposed to either vinclozolin or procymidone. Animals were castrated and administered silastic implants with or without testosterone. A subset of testosterone treated animals was then dosed with 200 mg/kg of either fungicide in corn oil. Four treatment groups were used: castrated (C), testosterone (T), testosterone+vinclozolin (V), and testosterone+procymidone (P). Tissue from the VP was collected from six animals per group (3 animals per block x 2 blocks) at 20 h and at 4 days after the start of treatment. Total RNA was then isolated and gene expression analyzed using Clontech Atlas Rat 1.2 Toxicology arrays. When compared to group T, similar changes in gene expression were observed in groups C, P and V at both the 20 h and 4 day time points. After 20 h of treatment, 20 genes were similarly affected across these three treatment groups. Down-regulated genes included various molecular chaperones, the 11-kDa diazepam binding inhibitor, cyclin D1, and mitochondrial aspartate aminotransferase. Genes such as the androgen receptor, PTEN, and ERK2 were up-regulated. Three of the down-regulated genes, GRP78 (BiP), Dad1, and mitochondrial aspartate aminotransferase have been previously shown to be directly androgen regulated. Fifty-four genes were affected at 20 h, whereas, 311 genes were altered 4 days after the start of treatment. These observations, in part, may reflect regression of the VP at the later time point. These results support the hypothesis that procymidone and vinclozolin share a common mechanism or mode of action, a critical step in a cumulative risk assessment.

AN - 67396724; 15686864 AB - Recent advances in developmental biology have yielded detailed models of gene regulatory networks (GRNs) involved in cell specification and other processes in embryonic differentiation. Such networks form the bedrock on which a systems biology approach to developmental toxicology can be built. In this review, an introduction to GRNs in general is followed by a description of specific networks involved in sea urchin and Drosophila development. A hypothesis is presented regarding the role of GRN analysis in the determination of mechanisms of chemical toxicity during embryonic development. Potential for future directions and research approaches in this area is discussed. JF - Reproductive toxicology (Elmsford, N.Y.)

AN - 67389122; 15683165 AB - Desorption kinetics were determined for fluoranthene (FLU) and trifluralin (TF) spiked onto Lake Erie and Lake Huron, USA, sediments at three concentrations (10, 40, 100 mg/kg dry wt). Following four months of equilibration, desorption was measured by extraction with Tenax and the data were fit to a first-order three-compartment kinetic model. The rate constants of the rapidly (k(rap)), slowly (k(slow)), and very slowly (k(vs)) desorbing fractions were on the order of 10(-1)/h, 10(-2-3)/h, and 10(-4)/h, respectively. The t99.9 (time required for 99.9% of the FLU and TF to desorb from each pool value) for each compartment indicated that FLU and TF desorption from rapid, slow, and very slow compartments were on the order of hours, days, and years, respectively. Higher rates of desorption were observed for FLU and TF from the Lake Huron sediments and this was not apparently related to the total organic carbon (TOC), particle size distribution, or polarity (carbon-to-nitrogen ratio) of the sediments. In general, the total fraction of the initial contaminant amounts that desorbed over the time course was directly related to concentration, which we hypothesized was due to the combined effects of saturation of high-energy (slow and very slow) binding sites in the organic carbon matrix and hysteresis. In extrapolations to field conditions, FLU and TF were predicted to persist in the sediments for years due to the very slow desorption of an estimated 31 to 53% of the bulk concentrations. Based on the rapidly desorbing fractions, the bioavailable amounts of the contaminants were predicted to be between 31 to 55% of bulk sediment concentrations.

AN - 67388309; 15683183 AB - Common carp (Cyprinus carpio) were treated in aquatic mesocosms with a single pulse of the herbicides atrazine or alachlor to study the bioavailability and biological activity of these herbicides using molecular indicators: Liver vitellogenin gene expression in male fish for estrogenic activity, liver cytochrome P4501A1 gene expression, and DNA damage in blood cells using the single-cell gel electrophoresis method. Both alachlor and atrazine showed dose-related increases in DNA strand breaks at environmentally relevant concentrations (<100 ppb). Gene expression indicators showed that neither herbicide had estrogenic activity in the carp, whereas atrazine at concentrations as low as 7 ppb induced cytochrome P4501A1. These results support the study of molecular indicators for exposure in surrogate ecosystems to gauge relevant environmental changes following herbicide treatments.

AN - 67375611; 15657811 AB - Although mercury contamination of fish is a widespread phenomenon, its regional evaluation is hindered by the reluctance of permitting agencies to grant collection permits, problems in securing adequate freezer space, and time to process whole, large fish or filets. We evaluated mercury concentrations in 210 filet biopsies from 65 sites in 12 western states relative to whole-body mercury concentration in the same fish. We found a highly significant relationship (r(2) = 0.96) between biopsy and whole-fish mercury concentrations for 13 piscivorous and nonpiscivorous fish species. We concluded that relative to conventional fish-tissue sampling and analysis procedures for whole fish or filets, the biopsy procedure for mercury in fish tissue is nonlethal, less cumbersome, more likely to be permitted by fisheries agencies, and a precise and accurate means for determining both filet and whole-fish mercury concentrations.

Part 2. History, recurring issues, practices, and guidelines. AN - 67374712; 15652225 AB - One challenge for most scientists is avoiding and resolving issues that center around authorship and the publishing of scientific manuscripts. While trying to place the research in proper context, impart new knowledge, follow proper guidelines, and publish in the most appropriate journal, the scientist often must deal with multi-collaborator issues like authorship allocation, trust and dependence, and resolution of publication conflicts. Most guidelines regarding publications, commentaries, and editorials have evolved from the ranks of editors in an effort to diminish the issues that faced them as editors. For example, the Ingelfinger rule attempts to prevent duplicate publications of the same study. This paper provides a historical overview of commonly encountered scientific authorship issues, a comparison of opinions on these issues, and the influence of various organizations and guidelines in regards to these issues. For example, a number of organizations provide guidelines for author allocation; however, a comparison shows that these guidelines differ on who should be an author, rules for ordering authors, and the level of responsibility for coauthors. Needs that emerge from this review are (a) a need for more controlled studies on authorship issues, (b) an increased awareness and a buy-in to consensus views by non-editor groups, e.g., managers, authors, reviewers, and scientific societies, and (c) a need for editors to express a greater understanding of authors' dilemmas and to exhibit greater flexibility. Also needed are occasions (e.g., an international congress) when editors and others (managers, authors, etc.) can directly exchange views, develop consensus approaches and solutions, and seek agreement on how to resolve authorship issues. Open dialogue is healthy, and it is essential for scientific integrity to be protected so that younger scientists can confidently follow the lead of their predecessors.

Part 1. A window into scientific fraud? AN - 67374674; 15652224 AB - The examination of a single scientific manuscript seldom alerts scientists, reviewers, editors, and scientific administrators to the fabrication and falsification of data and information. This review shows that most documented cases of scientific fraud involve falsification (altering truthful information) and fabrication (inventing information where none previously existed). Plagiarism is much less frequent. The review of published accounts also shows that the publication of scientific papers containing recognizable fraudulent material is very low, probably less than 0.02% and extremely difficult to detect. Because most reported cases of fraud have involved research done at prestigious organizations with distinguished co-authors, and that is published in journals with exacting review processes, it becomes evident that some unscrupulous scientists are adept at fabricating and falsifying data. However, "significant" scientific fraud is detected when scientists repeatedly report results that cannot be independently verified, when colleagues report suspicious behavior, or scientific audits are performed. This review documents and compares many of the better-known cases of scientific fraud. Fraudulent behavior has served as the impetus for the scientific community to develop publication procedures and guidelines that help to guard against not only fraudulent behavior but also against other types of unethical or undesirable behaviors. A companion paper reviews the non-fraudulent issues associated with scientific publication.

AN - 67362505; 15647535 AB - The Nuclear Regulatory Commission (NRC) announced the availability of three new documents concerning radioactive materials in sewage sludge and ash from publicly owned treatment works (POTW). One of the documents is a report presenting the results of a volunteer survey of sewage sludge and ash samples provided by 313 POTWs. The second document is a dose modeling document, using multiple exposure pathway modeling focused on a series of generic scenarios, to track possible exposure of POTW workers and members of the general public to radioactivity from the sewage sludge or ash. The third document is a guidance report providing recommendations on the management of radioactivity in sewage sludge and ash for POTW owners and operators. This paper explains how radioactive materials enter POTWs, provides criteria for evaluating levels of radioactive material in sludge and ash, and gives a summary of the results of the survey and dose modeling efforts.

AN - 67359097; 15647547 AB - Today's land application practices are designed to effectively treat wastes, and have evolved from earlier practices that centered on cheap disposal with less regard for environmental protection. The major objectives of this paper are to (i) review how current land application practices, and our understanding of them, have evolved over time and (ii) explore how science is used (and sometimes misused or ignored) in the development of design, regulation, and management of sustainable land application. Land treatment technologies have been used effectively for the treatment and recycling of many types of wastewaters and organic residuals for many years. Extensive research and demonstration efforts, as well as experience with pilot- and field-scale projects, have provided the information about soil reactions with contaminants in wastewater and organic residuals needed to design and operate sustainable land application projects. Still, systematic research programs are as important today as ever to support studies aimed at producing information on how soil-based treatment and recycling systems work, to address new areas of concerns as they arise, and continue to improve the overall design, performance, and reliability of land application systems as sustainable soil treatment and recycling systems.

AN - 67340068; 15562291 AB - The International Society for Exposure Analysis (ISEA) and its Nomenclature Committee have been involved since the mid-1990s in an intermittent but ongoing effort to develop an official ISEA glossary. Several related activities have stimulated greater interest and discussion nationally and internationally on a common exposure language. Among these activities are a 1997 Journal of Exposure Analysis and Environmental Epidemiology feature article on exposure and dose definitions and a 1999-initiated project of the International Programme on Chemical Safety (IPCS) (WHO/ILO/UNEP) to confront terminology issues hindering harmonization in the area of exposure assessment. Recently, the ISEA members voted in support of adopting the IPCS glossary as the official ISEA glossary, and the ISEA Executive Board agreed to accept this recommendation. In this feature article, we (1) describe the process through which the ISEA adopted the IPCS glossary as the official ISEA glossary, (2) present the joint IPCS/ISEA glossary of terms and their definitions, and (3) discuss plans for how the glossary can be used by ISEA and updated over time by ISEA and IPCS. The glossary is intended to be a living document that reflects the latest usage and maintains international harmonization of exposure terminology that can be practically applied to improve communication in exposure and related fields.

AN - 67338697; 15626651 AB - During the 2000-2002 time period, between 36 and 56% of ozone monitors each year in the United States failed to meet the current ozone standard of 80 ppb for the fourth highest maximum 8-hr ozone concentration. We estimated the health benefits of attaining the ozone standard at these monitors using the U.S. Environmental Protection Agency's Environmental Benefits Mapping and Analysis Program. We used health impact functions based on published epidemiologic studies, and valuation functions derived from the economics literature. The estimated health benefits for 2000 and 2001 are similar in magnitude, whereas the results for 2002 are roughly twice that of each of the prior 2 years. The simple average of health impacts across the 3 years includes reductions of 800 premature deaths, 4,500 hospital and emergency department admissions, 900,000 school absences, and > 1 million minor restricted activity days. The simple average of benefits (including premature mortality) across the 3 years is 5.7 billion dollars [90% confidence interval (CI), 0.6-15.0] for the quadratic rollback simulation method and 4.9 billion dollars (90% CI, 0.5-14.0) for the proportional rollback simulation method. Results are sensitive to the form of the standard and to assumptions about background ozone levels. If the form of the standard is based on the first highest maximum 8-hr concentration, impacts are increased by a factor of 2-3. Increasing the assumed hourly background from zero to 40 ppb reduced impacts by 30 and 60% for the proportional and quadratic attainment simulation methods, respectively.

After considering the meaning of the prefix 'non' in this context, specific examples are given of what nonformal education might include -- eg, after-school programs, museum visits, library visits, field trips, nature walks, family activity programs -- it is argued that their evaluation must be conducted in the context of the program itself, which requires elasticity, transformation, & collaboration on the part of evaluators: They must have the flexibility to anticipate & welcome diversity in the activities & goals of the specific program. They must transform themselves from outside evaluators to partners in the program. And they need to collaborate with the various stakeholders involved -- from program leaders to sponsoring organizations, to fundraisers.

Data were collected from more than 35 wells and 4 surface-water sampling sites located in a 0.59 square-mile basin to examine detailed hydrogeology and geochemical processes affecting nutrient fate and transport. Two additional surface-water sampling sites were located downstream from the primary study site to evaluate basin-scale effects. Chemical and flow data also were collected at an additional 10 sites in the Coastal Plain portion of the Neuse River basin located between Kinston and New Bern, North Carolina, to evaluate loads transported in the Neuse River and primary tributary basins.

One of these tools, developed by the U.S. Geological Survey (USGS), is used with available water-quality data obtained from USGS National Water-Quality Assessment (NAWQA) and other studies in association with land cover, geology, soils, and other geographic data to develop logistic-regression equations that predict the vulnerability of ground water to nitrate concentrations exceeding specified thresholds in the Mid-Atlantic Region. The models were developed and applied to produce spatial probability maps showing the likelihood of elevated concentrations of nitrate in the region. These maps can be used to identify areas that currently are at risk and help identify areas where ground water has been affected by human activities.

AN - 51569996; 2006-057731 AB - Alpha particles have been measured coming from the surfaces of rocks covered with dark red-brown rock varnish, as well as rocks that appear to have little, if any, varnish. A pronounced peak at 5.3 MeV indicates the presence of (super 210) Po, a short-lived natural-radioactive element. Surface activities for 33 samples range from 0.008 Bq/cm (super 2) to 0.065 Bq/cm (super 2) . It is estimated that this nuclide is concentrated 10 (super 11) times in these paper-thin coatings above its concentration in ground-level air. Gamma rays from the decay of (super 137) Cs, a product of testing nuclear weapons some 50 years ago, were also detected. Analysis of samples of varnish stripped from the rock revealed traces of (super 239,240) Pu and (super 238) Pu. The presence of all of these isotopes strongly supports the theory that varnish films derive their building blocks from the atmosphere and, with time, all rocks in arid environments will become coated.

A numerical modelling study has been undertaken to test the confidence in this understanding. This study has included three activities: recharge estimation, water balance calculations and steady-state groundwater flow modelling. It has been confirmed that the highest recharge is found in the NW of the basin and that the peat and marine clay deposits limit direct recharge in the east and south. The water balance is dominated by surface water flow, in particular the River Nith brings over 3200 Ml day (super -1) onto the basin. Conceptualized flow directions were confirmed by the steady-state modelling. The understanding and model validity are severely constrained by a lack of flow data in the lower River Nith and scarcity of water level and aquifer property information. These knowledge gaps could be filled by flow gauging just above the tidal limit of the river and additional drilling and testing.

Groundwater from these aquifers usually has an important influence on the hydrology, hydrochemistry and ecology of upland river systems. Tracer-based research in the Girnock Burn catchment in the Cairngorms revealed that groundwater comprises at least 30% of annual runoff. Groundwater often enters stream channels via drift deposits in valley bottom areas, which appear to be fed from recharge areas on the catchment interfluves. A range of groundwater sources exist in the catchment reflecting the complex solid and drift geology. These account for spatial differences in stream hydrochemistry and the spatial delineation of groundwater discharges to rivers and riparian zones. Areas where groundwaters enter the stream channel directly can have profound ecological implications. Most obvious are low rates of salmonid egg survival where chemically reduced groundwater discharges through the hyporheic zone. However, it is argued that only further research will reveal the full significance of groundwater-surface water interactions to the ecological status of Scottish rivers.

Using the methodology, a new GIS-based map of groundwater vulnerability has been produced, at a working scale of 1:100 000. The map is being used by the Scottish Environment Protection Agency (SEPA) to help characterize and assess risk to groundwater bodies. The methodology assesses the vulnerability of groundwater in the uppermost aquifer to the vertical downward movement of a non-specific contaminant from the ground surface. It considers the intrinsic properties of the pathway between the ground surface and the water table. The key difference from previous vulnerability maps in Scotland and the rest of the UK is that the new method assesses vulnerability in all aquifers regardless of resource potential. This reflects the diverse environmental objectives for groundwater bodies under the Water Framework Directive. This approach provides the flexibility to combine the groundwater vulnerability map with maps of pressures, groundwater resources or other groundwater-related receptors, as required.

The time scale allowed for the WFD initial characterization required a pragmatic methodology for efficient assessment of recharge to each delineated groundwater body. An assessment methodology was developed through a project funded by the Scotland and Northern Ireland Forum for Environmental Research, although it has application throughout the UK. Few recharge calculations have previously been attempted in Scotland. The environmental influences on recharge processes differ from much of the rest of the UK and the ability of the groundwater body to accept recharge is a key criteria. The method proposed is based on a water budget approach which estimates direct and indirect recharge flow components. It includes estimation of effective rainfall, actual evapotranspiration, surface run-off and interflow in addition to the potential impacts of snow-melt, bypass flows, urban recharge and surface water leakage where appropriate. This is calculated on a daily or monthly time step with the use of a spreadsheet software tool. The degree of uncertainty in the recharge estimation increases with the scarcity of data available to the groundwater body. Many recharge estimations in Scotland will rely on national-scale mapping of climatic, land use, soil and aquifer properties. It is important that the confidence in the estimation is balanced against the perceived risk of stress to the groundwater body. Validation of the recharge calculations is ongoing and the assessment of bypass flow and interflow has been determined as critical to the accuracy of the calculation.

The pollution of groundwater by nitrate can impact drinking water in aquifers in addition to the quality of base-flow to many streams and rivers. European legislation (in the form of the Nitrates Directive) requires that waters with a nitrate concentration of greater than 50 mg-NO (sub 3) l (super -1) (and those at risk of exceeding this concentration) should be identified and the catchment areas designated as Nitrate Vulnerable Zones (NVZs). Groundwater NVZs for Scotland were developed using a risk-based methodology which combined several Scottish national scale datasets in a GIS. The risk of nitrate leaching was determined from soil, climate and land use data. Digital solid and superficial geology data (at 1:50 000 scale) were interpreted to give an indication of aquifer vulnerability. The final zones were then determined by identifying local surface water catchments associated with areas of greatest nitrate leaching and aquifer vulnerability. The results of the vulnerability/risk analysis were broadly consistent with the available nitrate data for much of Scotland. Groundwater nitrate data were collated from the monitoring network of the Scottish Environment Protection Agency (SEPA), water authority boreholes and private water supplies, with additional new data collected from targeted sites. Within the NVZs, 25% of approximately 1700 samples exceeded 50 mg-NO (sub 3) l (super -1) compared to the rest of Scotland, where less than 5% of approximately 700 samples exceeded this concentration. The nitrate vulnerable zones have now been designated by the Scottish Executive and action programmes established to reduce nitrate contamination in these areas.

The Water Framework Directive (2000/60/EC) (WFD) requires a characterization report to be submitted to the European Commission in March 2005 describing the characteristics of our groundwater, an analysis of human impact and an assessment of the risk of failing to meet the environmental objectives set out in the directive. This has provided a driver to both rapidly improve the information available and to develop tools to assess the impact of human activity on this resource. Risk assessment methodologies have been developed to be consistent and reproducible and are based on simple science and national datasets. They use the concepts of pressure, pathway susceptibility and receptor sensitivity. Where a body is identified as being "at risk", further characterization work will be required, followed by targeted monitoring. Methodologies, data availability and risk assessments will be refined as the work progresses. It is likely that some bodies identified as being at risk of failing to meet the WFD environmental objectives in the initial screening exercise will be classified as good status as more reliable information becomes available.

Groundwater is present both in the bedrock, where much of the flow is through fractures, and in the superficial deposits, where intergranular flow dominates. The most productive bedrock aquifers are the Permian sandstones and breccia in SW Scotland and the Devonian sandstones in Fife, Strathmore and Morayshire. Alluvium and fluvio-glacial sands and gravels can also form important aquifers and provide some of Scotland's most highly yielding boreholes. Groundwater is generally weakly mineralized with total dissolved solids in the range 100 to 500 mg l (super -1) and is dominated by Ca and HCO (sub 3) type waters. There are in excess of 4000 boreholes in Scotland, and over 20 000 springs and wells used for private water supply. There are few available reliable data on the total volumes of groundwater abstracted; however, conservative estimates suggest that the total volume is approximately 330 megalitres per day for public water supply, industry, agriculture and private water supply. The volume of groundwater used in public water supply is growing annually; it is currently 7% of the daily 2400 megalitres per day supplied by Scottish Water. Scottish groundwater is under threat from agricultural activity, the mining legacy, septic tanks, localized high abstraction, and general land development. The implementation of the Water Framework Directive, and associated legislation, is an excellent opportunity to sustainably manage and develop groundwater in Scotland.

This is not a straightforward task, given that such aquifers are heterogeneous, discontinuous and strongly three-dimensional in the distributions of both hydraulic and hydrochemical properties. The Geological Survey of Norway has recently carried out characterizations of Norway's hard rock aquifers using simple non-parametric statistical techniques, focusing on median and percentile values for aquifer properties and concentrations of chemical parameters. Such characterizations reveal far larger parameter ranges within given aquifer lithological units than between different units. Indeed, for most lithologies, median well yields and concentrations of major chemical parameters (e.g. pH, major ions) are remarkably similar. For certain elements, however, systematic differences can be detected. For example, elements such as uranium, radon and fluoride are significantly enriched in Precambrian granites and gneisses, and depleted in anorthosites.

The practicum was tied together by a general research question (Are spatial patterns of Lake Ontario productivity a function of distance from the shoreline?), and a guided inquiry approach was used to help students frame testable hypotheses to address this question. Students collected a research-quality data set while participating in the practicum's teaching models, and subsequent to the cruise presented their results as oral papers at research conferences and as research papers. The design of this practicum may provide a useful model for other educators who wish to train the next generation of Great Lakes limnologists by conducting courses on a research vessel.

The interactions among these two landscape-scale factors on streams are, however, poorly understood. To determine the effects of these factors on stream flow, sediment, and nutrients, we analyzed 72 ungaged, agricultural watersheds in Minnesota and Michigan using the hydrologic model SWAT (the Soil Water Assessment Tool). The watersheds differed in surficial geology (landform) and land use, but were of similar size, with streams ranging from 2nd to 3rd order. SWAT was developed for use on ungaged basins, but to improve the outputs we used US Geological Survey discharge data from sites near our study watersheds for calibration. We found seasonal and annual differences in flow and nutrient and sediment loading across different land forms and land use types. Watersheds with greater amounts of row-crop agriculture and watersheds dominated by morainal landforms were associated with more sediment and nutrients and greater flow volumes and flashiness. Multivariate analyses identified at least nine landscape variable which were related to nutrients, sediment, and flow, although the responses varied between Minnesota and Michigan. Results also indicated the possibility of a threshold effect for row crop agricultural. Increases in this land use had little additional effect on nutrients or flow when percent row crop exceeds the threshold value. At moderate to high levels of row crop agriculture, water-sheds appeared to show greater sensitivity to differences in landform.

In the year 2002, the geometric mean concentration of TBA was 839 mu g/L compared to 627 mu g/L for MTBE. There are two plausible sources of TBA, the TBA originally present in the gasoline and biodegradation of MTBE to TBA. Thirteen sites where the concentration of TBA was >10 mg/L were selected for study. Biodegradation was evaluated by determining the stable carbon isotope ratio (delta (super 13) C) of MTBE in the ground water. If MTBE was biodegraded, the residual MTBE should be enriched in the heavier carbon isotope (super 13) C. The historical highest concentration of MTBE in each monitoring well and the delta (super 13) C of MTBE in the ground water were used to estimate the concentration of TBA produced from biodegradation of MTBE. Then, the estimated concentration of TBA was compared to the measured concentration. At each site, comparisons were made for the well in the source area, and the well in the plume outside the source area, that had the highest concentration of TBA. In the wells in the source areas, the estimate of TBA production accounted for the majority of TBA at 4 of the 13 sites. In the wells in the plume outside of the source area, the estimate accounted for the majority of TBA at six sites.

Although such exchange quantity between stream and aquifer may be relatively small in comparison with the stream discharge in the rainy season, the interaction between both is one of the important factors governing the stream flow condition with small discharge in the dry season and/or in the downstream from the intake dam. Because a remarkable decrease in the discharge affects both water quantity and quality and temperature, it may be necessary to keep a minimum discharge in order to preserve the river environment including ecological integrity. In this paper, for evaluation of the minimum discharge, the stream-aquifer interaction and its effects on the stream flow condition are investigated through field observations and a hydraulic model. According to the observations in an alluvial fan of the Yasu River in Japan, it is thought that variation of the stream discharge may be caused by the water exchange with aquifer. The findings from the hydraulic computations indicate that the model is a useful tool for quantitative evaluation of the minimum discharge required to maintain suitable stream flow conditions.

Most case studies and laboratory studies in the literature indicate that natural biodegradation is not important; however, recent reports indicate that natural biodegradation of MTBE plays an important role under certain conditions. In an MTBE plume at a retail gasoline station in Parsippany, New Jersey, the longterm monitoring data indicated that the concentration of MTBE was slowly declining over time in the wells that were within the footprint of the plume. The ratio of tert-butyl alcohol (TBA) to MTBE increased with distance from the source area, and the ratio of TBA to MTBE in individual monitoring wells in the plume increased over time. This anecdotal evidence of natural biodegradation of MTBE to TBA at field scale was confirmed with a microcosm study. Core material from the interior of the plume was used to construct the microcosms. Following an initial lag period of 58 d, the concentration of MTBE decreased from more than 1460 mu g/L to less than 10 mu g/L within 199 d of incubation. As concentrations of MTBE declined in the microcosms, concentrations of TBA increased. The decrease in concentration of MTBE in the microcosms could be accounted for by an increase in the concentration of TBA.

Techniques are needed to predict the vertical extent of MTBE in an aquifer. Two techniques that are emerging in the site characterization market are electrical conductivity logging and pneumatic slug testing performed in temporary push wells. These techniques were evaluated at a diving plume of MTBE in the aquifer that supplies water to the village of East Alton, Illinois. The plume stayed near the water table for the first 100 m from the potential sources and then dived below conventional monitoring over the next 100 m. At the location where the MTBE plume dived, the depth to water was 9.1 m below land surface. The first 10 m of material below the water table had an electrical conductivity near 100 mS/m, indicating silts and clays. An electrical conductivity near 25 mS/m, indicating sands or gravels, was encountered at a depth of 10.6 m below the water table, and the sands and gravel extended to a depth of at least 15.2 m below the water table. Pneumatic slug tests measured low hydraulic conductivity in the interval of silt and clay (0.34 and 0.012 m/d) and higher hydraulic conductivity in the interval with sands and gravels (12.5, 11.6, and 11.3 m/d). Ground water with the highest concentration of MTBE was produced just below the contact between the silt and clay and the sands and gravel.

Although the use of most POPs is banned in most countries, some organochlorine pesticides are still being used in several parts of the world. Although environmental levels of some POPs such as polychlorinated biphenyls (PCBs) have declined, newly emerging POPs such as polybrominated diphenyl ethers (PBDEs) have been increasing considerably. Exposure to POPs has been associated with a wide spectrum of effects including reproductive, developmental, immunologic, carcinogenic, and neurotoxic effects. It is of particular concern that neurotoxic effects of some POPs have been observed in humans at low environmental concentrations. This review focuses on PCBs as a representative chemical class of POPs and discusses the possible mode(s) of action for the neurotoxic effects with emphasis on comparing dose-response and structure-activity relationships (SAR) with other structurally related chemicals. There is sufficient epidemiological and experimental evidence showing that PCB exposure is associated with motor and cognitive deficits in humans and animal models. Although several potential mode (s) of actions were postulated for PCB-induced neurotoxic effects, changes in neurotransmitter systems, altered intracellular signalling processes, and thyroid hormone imbalance are predominant ones. These three potential mechanisms are discussed in detail in vitro and in vivo. In addition, SAR was conducted on other structurally similar chemicals to see if they have a common mode(s) of action. Relative potency factors for several of these POPs were calculated based on their effects on intracellular signalling processes. This is a comprehensive review comparing molecular effects at the cellular level to the neurotoxic effects seen in the whole animal for environmentally relevant POPs.

Information on structural and functional characteristics of the testis in common marmosets ("marmoset" in this review) is critical for designing experiments, interpreting data collected, and determining relevance to humans in risk assessment. METHODS: This study provides a comprehensive review on testicular development, structure, function, and regulation in common marmosets. RESULTS: There is little information regarding testicular formation and development during gestation. Based on the overall pattern of embryonic development in marmosets, it is postulated that gonadal formation and testicular differentiation most likely takes place during gestational Week 6-12. After birth, the neonatal period of the first 2-3 weeks and the pubertal period from Months 6-12 are critical for establishment of spermatogenesis in the adult. In the adult, a nine-stage model has been used to describe the organization of seminiferous epithelium and multiple stages per tubular cross-section have been observed. Seminiferous epithelium is organized in a wave or partial-wave manner. There are on average two stages per cross-section of seminiferous tubules in adult marmoset testis. Sertoli cells in the marmoset have a uniform morphology. Marmoset spermatogenesis has a high efficiency. The prime determinant of germ cell production is proliferation and survival of spermatogonia. Sertoli cell proliferation during the neonatal period is regulated by follicle- stimulating hormone (FSH), but chorionic gonadotropin (CG), instead of luteinizing hormone (LH), is the only gonadotropin with luteinizing function in marmoset. The receptor gene for CG in marmoset is unique in that it does not have exon 10. Marmosets have a "generalized steroid hormone resistance," i.e., relatively high levels of steroid hormones in circulation and relatively low response to exogenous steroids. Blockage of FSH, CG, and testosterone production during the first 3 months after birth does not cause permanent damage to the male reproductive system. Initiation of spermatogenesis in the marmoset requires unique factors that are probably not present in other mammals. Normal male marmosets respond to estradiol injection positively (increased LH or CG levels), a pattern seen in normal females or castrated males, but not usually in normal males of other mammalian species. CONCLUSIONS: It seems that the endocrine system including the testis in marmosets has some unique features that have not been observed in rodents, Old World primates, and humans, but detailed comparison in these features among these species will be presented in another review. Based on the data available, marmoset seems to be an interesting model for comparative studies. However, interpretation of experimental findings on the testicular effects in marmosets should be made with serious caution. Depending on potential mode of testicular actions of the chemical under investigation, marmoset may have very limited value in predicting potential testicular or steroid hormone-related endocrine effects of test chemicals in humans.

There are no federal regulations governing water reuse and criteria are developed at the state level. Criteria differ between states that have adopted regulations or guidelines, but criteria among states where water reuse is prevalent are similar and tend to be conservative, with public health protection being the most important consideration. The US Environmental Protection Agency (EPA) has published guidelines for water reuse that include recommended criteria for various reclaimed water applications.

Analysis of soil data from Queensland indicates that gidgees environmental domain has a broad overlap with treeless Mitchell grassland although a preference for slightly coarser soils with higher phosphorus and lower potassium content. Mapping of woody cover change for an area of central Queensland suggests that gidgee thickening and spread has occurred between 1951 and 1994. However, this increase has been more than offset by loss of gidgee cover by clearing in other areas. Gidgee thickening and encroachment onto grassland is a problem for graziers because the trees suppress grass and are unpalatable except when very young. Landholder surveys and other information indicate that gidgee has recruited sporadically and that thickening occurred with a massive seedling recruitment in the 1950s with a smaller recruitment wave in the 1970s. These waves coincide with relatively wet times and the extreme rainfall abundance in the 1950s has a multi-century expected recurrence. There are historical records describing gidgee death during the extreme droughts in the first part of the 20th century. Young gidgee plants are fire sensitive but well-established gidgee stands are fire retardant, and the importance of fire for control of gidgee thickening is unknown. One scenario explaining gidgee dynamics emphasises the role of environment (mostly climate and soil), while another emphasises management (mostly fire). Research priorities are presented and may contribute to appropriate management of gidgee woodlands.

On the 25th anniversary of Environmental and Molecular Mutagenesis, we think it is important to provide a brief overview of the currently available genetic toxicity tests and to outline a framework for conducting weight-of-the-evidence (WOE) evaluations that optimize the utility of genetic toxicology information for risk assessment. There are two major types of regulatory decisions made by agencies such as the Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA): (1) the approval and registration of pesticides, pharmaceuticals, medical devices, and medical-use products, and (2) the setting of standards for acceptable exposure levels in air, water, and food. Genetic toxicology data are utilized for both of these regulatory decisions. The current default assumption for regulatory decisions is that chemicals that are shown to be genotoxic in standard tests are, in fact, capable of causing mutations in humans (in somatic and/or germ cells) and that they contribute to adverse health outcomes via a genotoxic/mutagenic mode of action (MOA). The new EPA Guidelines for Carcinogen Risk Assessment [Guidelines for Carcinogen Risk Assessment, USEPA, 2005, EPA Publication No. EPA/630/P-03/001F] emphasize the use of MOA information in risk assessment and provide a framework to help identify a possible mutagenic and/or nonmutagenic MOA for potential adverse effects. An analysis of the available genetic toxicity data is now, more than ever, a key component to consider in the derivation of an MOA for characterizing observed adverse health outcomes such as cancer. We provide our perspective and a two-step strategy for evaluating genotoxicity data for optimal use in regulatory decision-making. The strategy includes integration of all available information and provides, first, for a WOE analysis as to whether a chemical is a mutagen, and second, whether an adverse health outcome is mediated via a mutagenic MOA.

This study was designed to examine the effects of these protocols on various types of surgical instruments. The most important conclusions are: (1) autoclaving in 1N NaOH will cause darkening of some instruments; (2) soaking in 1N NaOH at room temperature damages carbon steel but not stainless steel or titanium; (3) soaking in chlorine bleach will badly corrode gold-plated instruments and will damage some, but not all, stainless-steel instruments, especially welded and soldered joints. Damage became apparent after the first exposure and therefore long tests are not necessary to establish which instruments will be damaged.

The aim is to reduce the reliance on defaults that introduce a relatively high level of uncertainty to the risk estimates. The types of data required for this purpose are those that help identify key events in tumor formation following exposure to environmental chemicals. Informative biomarkers of tumor responses could then be developed for describing the shape of a dose-response curve at low doses (i.e., a qualitative assessment) and for predicting tumor frequency at these low doses (i.e., a quantitative assessment). A number of recently developed molecular approaches could aid in the development of qualitatively and quantitatively informative biomarkers. An overview of these with examples of their use is presented. These methods include quantitative gene expression array techniques, quantitative proteomic assays, and the assessment of DNA alterations at the single gene level and at the genome level of detection. It is most likely that a combination of approaches at different levels of cellular organization (i.e., DNA, RNA, and protein) will be the most productive for biomarker development. The rapid progress that is being made will make this tool kit even more applicable for the cancer risk assessment process.

Millions of people in Bangladesh and India are at risk through use of contaminated drinking water. When humans ingest inorganic arsenic, it is rapidly converted to methylated metabolites. Although this methylation process is largely understood, the metabolism of other arsenicals (e.g. arsenosugars to dimethylarsenic) is very unclear. Connections among pathways for metabolism of various arsenicals are now being elucidated. Commonalities and differences in these pathways may be important determinants of the risk associated with exposure to these agents. Elucidating the pathway of inorganic arsenic metabolism shows that some of methylated arsenicals formed as intermediates and products are reactive and toxic species. Hence, methylated arsenicals likely mediate at least some of the toxic and carcinogenic effects associated with exposure to arsenic. Trimethylarsonium compounds and arsenosugars are two other classes of arsenicals to which humans are routinely exposed and there is evidence that both classes are metabolized to produce methylated arsenicals. Here, we review evidence for production of methylated metabolism and consider the challenges posed in unraveling a complex web for metabolism of arsenicals in humans.

Original data are presented from a permanent monitoring site, suggesting that on average 27% of dead standing biomass is consumed per low-intensity fire. The consumption of standing dead wood by fire, together with likely 'fall-down rates', could offset a substantial proportion of recently estimated dead standing wood carbon sink. The potential for using existing allometric equations to ascribe biomass to the components of dead standing wood (trunks, branches, bark) on permanent monitoring plots is reviewed. Some valid generalisations can be recognised but a lack of standardisation in allometric studies presents problems. It is suggested that data from survey, monitoring and experiments could drive worthwhile models of dead standing wood biomass. This pool will probably vary substantially through time and space, depending on climatic conditions, fire and termite activity.

Beginning in the 1890s, the channel was greatly simplified for navigation. By the 1940s, it was polluted by organic wastes, which resulted in low dissolved oxygen concentrations and floating and benthic sludge deposits that hindered salmon migration and boating. Following basin-wide secondary waste treatment and low-flow augmentation, water quality markedly improved, salmon runs returned, and recreational uses increased. However, water pollution remains a problem as do physical habitat alterations, flow modification, and alien species. Fish assemblages in the main-stem Willamette River were sampled systematically, but with different gear, in the summers of 1945, 1983, and 1999. In the past 53 years, tolerant species occurrences decreased and intolerant species occurrences increased. In the past 20 years, alien fishes have expanded their ranges in the river, and four native fish species have been listed as threatened or endangered. We associate these changes with improved water quality between 1945 and 1983, fish migrations, altered flow regimes and physical habitat structure, and more extensive sampling.

Coral disease and bleaching in the Caribbean and South Florida have caused extensive coral mortality with limited recovery, often coral reefs are being replaced with turf algae. Acroporids were once dominant corals and have diminished to the state where they are being considered as endangered species. Our survey assessed the condition of reef corals throughout South Florida. A probability-based design produced unbiased estimates of the spatial extent of ecological condition, measured as the absence or presence and frequency or prevalence of coral diseases and bleaching intensity over large geographic regions. This approach allowed us to calculate a quantifiable level of uncertainty. Coral condition was estimated for 4100 hectares (ha) (or 41.0 km super(2)) of coral reefs in South Florida, including reefs in the Florida Keys National Marine Sanctuary (FKNMS), New Grounds, Dry Tortugas National Park (DTNP), and Biscayne National Park (BNP). The absence or presence of coral disease, 'causal' coral bleaching, partial bleaching and coral paling were not good indicators of overall coral condition. It was more useful to report the prevalence of anomalies that indicated a compromised condition at both the population and community levels. For example, 79% of the area in South Florida had less than 6% of the coral colonies diseased, whereas only 2.2% (97.15 ha) of the sampled area had a maximum prevalence of 13% diseased coral colonies at any single location. The usefulness of 'causal bleaching' might be more important when considering the prevalence of each of the three different states at a single location. For example, paling was observed over the entire area, whereas bleaching and partial bleaching occurred at 19 and 41% of the area, respectively. An index for coral reef condition might integrate the prevalence and species affected by each bleaching state at individual locations. By establishing these baselines, future surveys can examine changes and trends in the spatial distribution of coral conditions in South Florida and able to score the reefs as to their health status.

Since long-term field experiments are typically not feasible, vital rates such as survival and reproduction of individual organisms are measured in life table response experiments (LTRE) and employed to extrapolate the effects of a pollutant on the population. The population-level response of the mysid, Americamysis bahia, to varying concentrations of methoprene (0, 4, 8, 16, 31, 62 mu g/L) was determined using age-structured population models. Models were parameterized from the results of an LTRE conducted throughout the entire mysid life cycle. A density-independent matrix model with time invariant demographic parameters was developed to measure the change in population growth rate, lambda , with change in methoprene concentration. The values of lambda were greater than one for all methoprene concentrations, indicating that populations exposed to the concentrations reported here would not become extinct. However, a general decrease in lambda occurred with increasing methoprene concentration and would result in reduced population sizes. Sensitivity and decomposition analyses were conducted to determined the relative roles of the vital rates on altered population growth rates and determined that impaired reproduction was the primary influence on the observed decrease in lambda . The model constructed was a useful tool for linking the individual-level effects to the population-level consequences of methoprene exposure on mysids, as well as defining the mechanism (reduced reproduction) responsible for the observed effects on population.

The abiotic interactions of SoyOil with the CEs may be significant and need to be better understood. The oil: water partition coefficients (K sub(p)) of dissolved CEs into SoyOil were measured in batch tests and ranged from 22 to 1200 with increasing chlorination. CE mixtures significantly reduced the K sub(p) for tetrachloroethene (PCE), but not the other CEs. Simple flow tests were used to quantify the mass transfer coefficients (k sub(L)) of dissolved CEs into SoyOil. Higher k sub(L) values corresponded to the CEs with higher diffusivity in water. CE mixtures reduced the k sub(L) for all of the CEs. The results can be used to predict abiotic interactions and distribution of contaminant mass expected after SoyOil injection, and thus provide a more accurate estimate of the mass of CEs removed due to enhanced biodegradation.

Recently, consideration of urban impacts on waterways has expanded to include assessment of the aquatic biota, generally focusing upon the macroinvertebrate fauna. This study compares the impacts of urbanization on the structure of stream benthic diatom communities in 16 first- and second-order streams in the east of Melbourne, Australia. Relationships between the physical elements of urbanization, water quality and diatom communities were examined using multivariate analyses with compositional similarity, and univariate analyses with selected diatom species and indices,. There was a strong negative correlation between urban density and the diatom indices of water quality. The element of urbanization most strongly related to the measured decline in the diatom community was drainage connection. Electrical conductivity was the most influential water quality variable. It is hypothesized that, in addition to increasing electrical conductivity, drainage connection may be impacting the diatom community by increasing the delivery of phosphorus during small storm events. The study suggests that reducing directly piped drainage connection using infiltration and retention is a logical step in the mitigation of urban impacts upon receiving streams. A corollary part of the project indicated strong potential for using overseas diatom indices in studies on water quality in southeastern Australia.

Surface environmental sampling within the facility indicated that the contamination was due to receipt of mail that had come in contact with Bacillus anthracis spores from the source letters at the Brentwood postal facility in Washington, DC. The DOJ adopted a two-pronged approach for remediating the facility, using aqueous chlorine dioxide to decontaminate hard, nonporous surfaces and paraformaldehyde to fumigate two pieces of mail equipment. Before the start of the remediation activities, all porous materials were removed from the mail area. Since all postremediation environmental samples were negative for growth of Bacillus anthracis spores, the remediation was judged to be effective. The facility remained closed for almost 4 one half months. The cleanup activities took about 2 one half months, with source reduction activities being the most time-consuming. Of the seven facilities that performed fumigations to remediate Bacillus anthracis contamination, the DOJ mail facility was the second building to be reopened.

As part of the examination, aspects of ecological risk-assessment practices were reviewed. Several issues related to ecological risk assessment were identified, including the use of organism-level versus population-level attributes to characterize risk, the possible opportunities associated with the increased use of probabilistic approaches for ecological risk assessment, and the notion of conservatism in estimating risks. The agency examination provides an understanding of current practices and is intended to begin a dialogue in which the risk assessment community can engage in addressing the identified issues to improve and enhance ecological risk assessment.

Since 1990, some apparent trends in nutrient concentrations have been inconsistent with the predictions of models originally used to guide Lake Erie water quality management. We performed time trend analysis on total phosphorus (TP), chlorophyll a (Chl a), and dissolved reactive silica (DRS) measurements collected during spring and summer in the central basin of Lake Erie between 1983 and 2002. Three distinct time trends in basin-specific, station-averaged open-water TP concentrations were observed over the 20-year period: 1983-1989 decreases, 1990-1997 increases, and 1997-2001 decreases. Exceptionally high levels of turbidity and TP were observed in spring 2002, possibly reflecting increasing frequency of winter storm events. Open-water concentrations of TP declined during the 1980s as annual TP loadings to Lake Erie declined below the 11,000 metric ton target level that had been expected to reduce central basin eutrophication. This was accompanied by a significant increase in available silica and in Chl a concentrations. During the period 1990-2002, when dreissenid mussels were abundant, spring TP concentrations increased but summer TP concentrations declined. Unexpected increases in spring central basin concentrations of DRS (exceeding 1 mg/L) were observed. During the same period, Chl a concentrations declined in the spring and rose slightly during summer.

ER - TY - JOUR T1 - super(1)H-NMR metabonomics analysis of sera differentiates between mammary tumor-bearing mice and healthy controls AN - 19437773; 6758278 AB - Global analysis of super(1)H-NMR spectra of serum is an appealing approach for the rapid detection of cancer. To evaluate the usefulness of this method in distinguishing between mammary tumor-bearing mice and healthy controls, we conducted super(1)H-NMR metabonomic analyses on serum samples obtained from the following: 10 mice inoculated with a highly-metastatic mammary carcinoma cell line, 10 mice inoculated with a `normally" metastatic mammary carcinoma cell line, and 10 healthy controls. Following standard spectral processing and subsequent data reduction, we applied unsupervised Principal Component Analysis (PCA) to determine if unique metabolic fingerprints for different categories of metastatic breast cancer in serum exist. The PCA method correctly separated sera of tumor-bearing mice from that of normal healthy controls, as shown using the scores plot which indicated that sera classes from tumor-bearing mice did not share multivariate space with that from healthy controls. In addition, this technique was capable of distinguishing between classes of varying metastatic ability in this system. Metabolites apparently responsible for separation between diseased and healthy mice include lactate, taurine, choline, and sugar moieties. Results of this study suggest that super(1)H-NMR spectra of mouse serum analyzed using PCA statistical methods indicate separation of tumor-bearing mice from healthy normal controls, justifying further study of the use of super(1)H-NMR metabonomics for cancer detection using serum.

Heme oxygenase induction in mice AN - 17763180; 6133220 AB - Heme oxygenase (HO) is the rate-limiting enzyme in heme degradation and its activity has a significant impact on intracellular heme pools. Rat studies indicate that HO induction is a sensitive, dose-dependent response to arsenite (As( III)) exposure in both liver and kidney. The objective of this study was to evaluate the relationship of HO induction to administered As( III) dose, and concentrations of inorganic arsenic (iAs) in tissues and urine. Levels of iAs, mono-(MMA) and dimethylated arsenic (DMA) as well as HO activity were determined in liver, lung and kidney over time in female B6C3F1 mice given a single oral dose of 0, 1, 10, 30 or 100 mu mol/kg As( III). Increased HO activity was a time and dose-dependent response in liver and kidney, but not in lung. Activity peaked in the 4-6 h time range in liver and kidney with the responsiveness in liver being [not, vert, similar]2-to 3-fold greater than kidney. The lowest observed effect levels (LOELs) in this study for HO induction are 30 and 100 mu mol/kg, respectively, in liver and kidney. The predominant form of arsenic (As) was iAs in liver at all doses, whereas DMA was the predominant form of As in kidney at all doses. Three-to four-fold higher levels of iAs were achieved in liver compared to kidney. MMA was the least abundant form of As in liver and kidney, never exceeding more than 20% of the total As present. The concentration of iAs in tissue or urine demonstrated the strongest correlation with HO activity in both liver and kidney. Results of this study suggest that HO induction is a biomarker of effect that is specific for tissue iAs because a high, but nontoxic, acute dose of DMA (5220 mu mol/kg) did not induce HO in mice. Thus, HO induction has potential for use as a biomarker of effect for inorganic arsenic exposure and may be used as an indicator response to further the development of a biologically-based dose response model for As.

Equations for the road death rate (fatalities/population) and its components; the rate of motorization (vehicles/population) and fatalities per vehicle (F/V); are estimated using panel data from 1963 to 1999 for 88 countries. The natural logarithm of F/P, V/P, and F/V are expressed as spline (piecewise linear) functions of the logarithm of real per capita GDP (measured in 1985 international prices). Region-specific time trends during the period 1963-1999 are modeled in linear and log-linear form. These models are used to project traffic fatalities and the stock of motor vehicles to 2020. The per capita income at which traffic fatality risk (fatalities/population) begins to decline is $8600 (1985 international dollars) when separate time trends are used for each geographic region. This turning point is driven by the rate of decline in fatalities/vehicles as income rises since vehicles/population, while increasing with income at a decreasing rate, never declines with economic growth. Projections of future traffic fatalities suggest that the global road death toll will grow by approximately 66% over the next twenty years. This number, however, reflects divergent rates of change in different parts of the world: a decline in fatalities in high-income countries of approximately 28% versus an increase in fatalities of almost 92% in China and 147% in India. The road death rate is projected to rise to approximately 2 per 10, 000 persons in developing countries by 2020, while it will fall to less than 1 per 10, 000 in high-income countries.

Larval development of the grass shrimp, Palaemonetes pugio, was greater than two orders of magnitude more sensitive to disruption by methoprene and fenoxycarb than was embryonic development. Developing larvae of the mud crab, Rhithropanopeus harrisii, exhibited reduced metamorphic success at lower concentrations of methoprene and pyriproxyfen than grass shrimp larvae. These responses suggest that the more rigidly controlled metamorphic process in crabs is more sensitive to compounds acting as endocrine disruptors than is the more flexible metamorphic pattern in shrimp. The final crab larval stage, the megalopa, was more sensitive to methoprene and fenoxycarb exposure than earlier zoeal stages. Mud crab larvae exposed to fenoxycarb had reduced biomass and lipid content, particularly triglycerides and sterols. Concentrations of fenoxycarb which reduced the reproductive capacity in single life-cycle exposures of the estuarine mysid, Americamysis bahia, were similar to those concentrations which inhibited metamorphosis in grass shrimp. Juvenile mysids released by exposed adults and reared through maturation without further exposure produced fewer young and had altered sex ratios (lower percentages of males) at lower parental-exposure concentrations than directly affected parental reproduction. These transgenerational responses may well be a product of irreversible effects during developmental exposures which become apparent following maturation and initiation of reproduction. These findings support using a functional approach as an appropriate screening procedure to evaluate potential environmental endocrine-disrupting chemicals in aquatic environments.

Regulatory compliance is an expectation, and a strong foundation, but not the final goal. The goal is to have ports practice environmental stewardship as part of their business strategy. This will help lead to the development of sustainable port communities, i.e., economically viable, environmentally and socially responsible, safe and secure. It is important for U.S. ports to be exemplary environmental stewards because they are experiencing unprecedented growths at the same time coastal populations are growing. Because of these growth trends, ports and their business partners are challenged to find ways to minimize their impacts on human health and the environment.

The procedure is illustrated with 42 embayments in southern New England, USA, giving special attention to Greenwich Bay, RI. The methodology uses simplifying assumptions. It efficiently uses available information wherever possible, and invokes experience where data are unavailable. It uses two-dimensional hydrodynamic and transport models to simulate tidal and subtidal circulation, flushing times, local residence times, and the distributions of conservative constituents over individual embayments. Preliminary results for a subset of the systems compare favorably with published values. The full set of results reveals relationships between flushing times and physical properties of the embayments. A set of relationships to estimate flushing and maximum residence times from the length and surface area of embayments in southern New England is also presented.

However, quantifying the flux is difficult, particularly in spatially heterogeneous environments. Surficial sediment chlorophyll-a, which can be measured quickly at many locations, has been used effectively by previous studies as an indicator of phytoplankton deposition to estuarine sediments. In this study, surficial sediment chlorophyll-a was quantified in late spring at 20-50 locations throughout Chesapeake Bay for 8 years (1993-2000). A model was developed to estimate chlorophyll-a deposition to sediments using these measurements, while accounting for chlorophyll-a degradation during the time between deposition and sampling. Carbon flux was derived from these estimates via C:chl-a=75.Bay-wide, the accumulation of chlorophyll-a on sediments by late spring averaged 171mgm super(-) super(2), from which the chlorophyll-a and carbon sinking fluxes, respectively, were estimated to be 353mgm super(-) super(2) and 26.5gC m super(-) super(2). These deposition estimates were similar to 50% of estimates based on a sediment trap study in the mid-Bay. During 1993-2000, the highest average chlorophyll-a flux was in the mid-Bay (248mgm super(-) super(2)), while the lowest was in the lower Bay (191mgm super(-) super(2)). Winter-spring average river flow was positively correlated with phytoplankton biomass in the lower Bay water column, while phytoplankton biomass in that same region of the Bay was correlated with increased chlorophyll-a deposition to sediments. Responses in other regions of the Bay were less clear and suggested that the concept that nutrient enrichment in high flow years leads to greater phytoplankton deposition to sediments may be an oversimplification. A comparison of the carbon flux associated with the deposition of the spring bloom with annual benthic carbon budgets indicated that the spring bloom did not contribute a disproportionately large fraction of annual carbon inputs to Chesapeake Bay sediments. Regional patterns in chlorophyll-a deposition did not correspond with the strong regional patterns that have been found for plankton net community metabolism during spring.

Health portals, which provide entry points to quality-controlled collections of websites, have been hailed as a solution to this problem. The objective of this study is to assess the extent to which government-run health portals provide access to relevant, valid and understandable information about the effects of health care. Methods: We selected eight clinically relevant questions for which there was a systematic review, searched four portals for answers, and compared the answers we found to the results of the systematic reviews. Results: Our searches resulted in 3400 hits, 155 of which mentioned both the condition and the intervention in one of the eight questions. Sixty-three of the 155 web pages did not give any information about the effect of the intervention. Seventy-seven qualitatively described the effects of the intervention. Twenty-six of these had information that was too unclear to be categorised; 15 were not consistent with the systematic review; and 36 were consistent with the review, but usually did not mention what happens without the intervention, what outcomes have been measured or when they were measured. Fifteen web pages quantitatively described effects. Four of these were abstracts from the systematic review, nine had information that was incomplete and potentially misleading because of a lack of information about people not receiving the intervention and the length of follow-up; one had information that was consistent with the review, but only referred to three trials whereas the review included six; and one was consistent with the review. Conclusions: Information accessible through health portals is unlikely to be based on systematic reviews and is often unclear, incomplete and misleading. Portals are only as good as the websites they lead to. Investments in national health portals are unlikely to benefit consumers without investments in the production and maintenance of relevant, valid and understandable information to which the portals lead.

We recorded the characteristics of 478 sap trees located at 109 of 297 sites surveyed. Only 13 tree species were selected by gliders for sap feeding throughout the study region, with the grey gum species Eucalyptus longirostrata and E. biturbinata most likely to be incised for sap. Of the tree species used for sap feeding by gliders, trees >40 cm in diameter at breast height (DBH) were used more than would be expected on the basis of their abundance in the forest. The number of sap trees with active and recently active feed scars at a site ranged from 0 to 12. Factors that appear to influence the abundance of active and recently active sap trees at a site include intensity of disturbance (basal area of cut stumps and dead trees), the number of stems in the 41-60 and 61-80 cm DBH classes, and number of Myrtaceae species. The response to these variables could be indicative of habitat quality, and the availability of alternative foraging substrates such as flower cover and decorticating bark. Intensification of selective logging in south-east Queensland, as an outcome of the Southeast Queensland Regional Forest Agreement, could potentially marginalise glider habitat. This would necessitate the retention of potential, or 'recruit', sap trees to maintain yellow-bellied glider habitat in these areas.

AN - 17446031; 6600905 AB - Elevated but moderate concentrations of nitrogen and phosphorus were maintained continuously for 2 years in a heavily shaded headwater stream and effects were compared on stream periophyton with a reference stream. Both streams were sampled for 1 year before treatment. Some measures of periphyton biomass (ash-free dry mass and chlorphyll a) responded positively to enrichment. Increased chlorophyll a was likely a result of higher chlorophyll per cell, as total algal biovolume did not change with enrichment. These differences were greatest during high-light months (November-May), when cellular growth rates (a proxy for production) were also highest with enrichment. Algal assemblages were dominated by diatoms and remained similar between the treatment and reference streams throughout the enrichment period. Although nutrients stimulated algal growth rates, the long-term effects of nutrient addition on periphyton biomass were small in magnitude compared with other published values and were potentially suppressed by light availability and invertebrate consumption. These and other factors may have also been important in limiting the algal species pool and thus a taxonomic response to enrichment. The results indicate that in headwater streams with intact tree canopies, chronic nutrient enrichment at moderate concentrations may have little detectable effect on benthic algal composition or periphyton biomass. Although nutrients stimulated algal growth rates, the long-term effects of nutrient addition on periphyton biomass were small in magnitude compared with other published values and were potentially suppressed by light availability and invertebrate consumption.

Environmental security is a term emphasising the connection between environmental health and socio-political issues, including traditional national security issues. An environmental security approach provides a very fruitful way to consider critical challenges facing Russia. Russia has profound environmental problems whose severity and pervasiveness could undermine its attempts to build political and economic stability. The natural resource base and human health have suffered, and continue to face, profound deterioration. Since the end of the Soviet system, there has been no significant progress in defining and addressing major environmental and associated health problems. Major barriers include a lack of legal, financial and civil infrastructures; an unreliable legal system; rampant criminal elements; and a lack of political accountability. The paper concludes with observations about possible avenues for improvement, by addressing fundamental infrastructure weaknesses, coupled with actions to staunch the outward flow of wealth, increase bilateral and multilateral agreements, and attract external capital.

The present study was designed to investigate both effects in Sprague-Dawley rats following an extended 20-week treatment with lower dosages of DBA administered in the drinking water (calculated mean intake concentrations of 5, 16, and 33 mg/kg/d). No treatment- related effects on cyclicity were present, although elevations in serum estradiol on the day of vaginal estrus were noted in regularly cycling rats when assessed at the 3rd and 11th weeks of exposure. By the 19th week, this effect was no longer present in cycling animals, but its absence was attributable to a marked increase in control estradiol concentrations, which may be associated with endocrine alterations that precede a disruption in estrous cyclicity in middle-aged females. In the 20th week, diestrous estrone levels were elevated at all dosages without effects on serum androstenedione or progesterone. Uterine and pituitary weights were unchanged at this time, although there were modest increases in liver weights at the two highest dosages. A small number of rats in persistent estrus (PE) did show a general increase in pituitary weight associated with DBA exposure, possibly reflecting an added layering of treatment on the PE-associated rise in estradiol normally seen in these females. The results indicate that increases in circulating estradiol from drinking water exposures to DBA were not linked to a premature disruption of estrous cyclicity in this moderately estrogen-sensitive rat strain.

SW spiked with predetermined concentrations of copper (Cu), cadmium (Cd), hexavalent chromium (Cr super(+6)), lead (Pb), zinc (Zn), and benzo[a]pyrene (B[a]P), naphthalene (NP), fluoranthene (FA), 1,3-dichlorobenzene (DCB), and butylbenzylphthalate (BBP) were used in this study. Each medium removed close to 100 percent of all the pollutants at the concentrations studied. Sorption capacities ([mu]g/g) of the three organic media were in the order of jute > hardwood mulch > softwood mulch, and on a mole basis, both the heavy metals and the toxic organics were sorbed by the three media in an identical sequence: Cr super(+6) > Cu, Zn > Cd > Pb; and NP > DCB > FA > B[a]P > BBP. Sorption capacities of the hardwood wood mulch and jute fiber for the pollutants were correlated with distinctive physical properties of the pollutants.

The O sub(2) levels and CO/CO sub(2) ratios of the open burn simulations are typical of the field fires of agricultural residues. In the AF plumes, we observe predominantly accumulation mode (100-1000 nm) aerosols. The mean PM sub(2.5) mass emission factors from replicate burns of the wheat and rice residuals are 4.7+/-0.04 and 13.0+/-0.3 g kg super(-1) of dry biomass, respectively. The combustion-derived PM emissions from wheat are enriched in K (31% weight/weight, w/w) and Cl (36% w/w), whereas the PM emissions from rice are largely carbonaceous (84% w/w). Molecular level gas chromatography/mass spectrometry analysis of PM sub(2.5) solvent extracts identifies organic matter that accounts for as much as 18% of the PM mass emissions. A scarcity of detailed PM-phase chemical emissions data from AFs required that comparisons among other biomass combustion groups (wildfire, woodstove, and fireplace) be made. Statistical tests for equal variance among these groups indicate that the degree to which molecular emissions vary is compound dependent. Analysis of variance testing shows significant differences in the mean values of certain n-alkane, polycyclic aromatic hydrocarbon (PAH), oxy-PAH, and sugar marker compounds common to the biomass combustion types. Individual pairwise comparisons of means at the combustion group level confirm this result but suggest that apportioning airborne PM to these sources may require a more comprehensive use of the chemical emissions fingerprints. Hierarchical clustering of source test observations using molecular markers indicates agricultural fuels as distinct from other types of biomass combustion or biomass species. Rough approximations of the total potential PM sub(2.5) emissions outputs from the combustion of the wheat and rice surface residues are given. This agricultural activity could significantly contribute to emissions inventories at regional, national, and global geographic levels.

Because of the relative youth of this enterprise, disciplinary interests sometimes compete and conflict with the primary goal of achieving protective, cost-effective, efficient projects. Convergence of viewpoints toward a more mature, common vision is needed. In addition, cleanup programs are changing under the influence of Brownfields initiatives and the needs of environmental insurance underwriters. Investigations and cleanups increasingly need to be affordable, yet transparent and defensible. Disciplinary goals and terminology need to better reflect real-world site conditions while being more supportive of project needs. Yet, technical considerations alone will not ensure project success; better integration of human factors into project management is also required. The Triad approach is well placed to catalyze maturation of the remediation field because it emphasizes (1) a central theme of managing decision uncertainty; (2) unambiguous technical communications; (3) shortened project life-cycles and multidisciplinary interactions that rapidly build professional expertise and provide feedback to test and perfect programmatic and field practices; and (4) concepts from "softer" sciences (such as economics, cognitive psychology, and decision theory) to capture important human factors. Triad pushes the cleanup industry toward an integrated, practical, second-generation paradigm that can successfully manage the complexities of today's cleanup projects.

We have examined the effects of a 1 year dietary exposure to the OP chlorpyrifos (CPF) on retinal structure and function. Adult male Long-Evans rats were fed CPF in their diet at the rate of 0, 1 (low), or 5 (high) mg/kg body weight/day. In addition, half of each feeding group received an oral (spike) dose of CPF in corn oil (45 mg/kg) or corn oil (VEH) alone every 2 months, resulting in six exposure groups: Control-VEH, Control-CPF, Low-VEH, Low-CPF, High-VEH, and High-CPF. Dark-adapted electroretinograms (ERG) were measured 3-5 months (n=15-18/group) after the completion of dosing. There were no significant differences between dose or spike groups in a-wave, b-wave, or oscillatory potential amplitudes or implicit times. In addition, the time course of dark adaptation were measured in a subset of these rats (6-8/group) eight months after the completion of dosing by determining the flash intensity needed to elicit a 40 mu V b-wave at selected intervals after bleaching 90% of the photopigment. Rats receiving the episodic oral spike of CPF showed a slowed recovery of dark-adapted sensitivity compared to rats receiving the corn oil VEH across chronic dosing conditions. No effects were seen on retinal morphology. This result suggests that episodic high dose exposures to CPF may result in altered retinal function. This effect, akin to effects seen in aging humans and humans exposed to other ChE-inhibiting compounds, may reflect alterations in the photoreceptors and retinal pigment epithelium (RPE) complex necessary for regenerating photopigment.

We collected zooplankton data with an OPC in 20 near-shore regions of 4 of the Laurentian Great Lakes. The zooplankton size information was used to compute mean size, biomass density, and size-spectra parameters for each location. The resulting metrics were analyzed for their ability to discriminate among the Great Lakes. Biomass density provided discrimination among lakes, as did several parameters describing spectra shape and distribution. A proposed zooplankton indicator, mean size (determined with OPC measurements in this study), was found to provide discrimination among lakes. Size-spectra-related parameters added increased ability to discriminate in conjunction with the biomass density (or mean size) metric. A discriminant function analysis of the multiple metrics (mean size, biomass density, and distribution parameters) suggests that a multi metric size-based approach might be used to classify communities among lakes improving a mean-size metric. The feasibility OPCs and size-based metrics for zooplankton assessment was found to have potential for further development as assessment tools for the biological condition of zooplankton communities in the Great Lakes.

Environmental PFOS may be from its use as a surfactant, hydrolysis of perfluorooctanesulfonyl fluoride, and degradation of N-alkyl-perfluorooctanesulfonamide compounds formerly used in numerous applications. Prenatal exposure to PFOS in rodents causes neonatal mortality; treatment on gestation days (GD) 19-20 is sufficient to induce neonatal death in rats. Affected pups are born alive but present with labored breathing. Their lungs are pale and often do not expand fully on perfusion. METHODS: Pregnant Sprague-Dawley rats received 0, 25, or 50 mg/kg/day PFOS/K super(+) orally on GD 19-20. Lungs from GD 21 fetuses and neonates were prepared for histology and morphometry. Rescue experiments included co- administration of dexamethasone or retinyl palmitate with PFOS. Pulmonary surfactant was investigated with mass spectrometry in GD 21 amniotic fluid and neonatal lungs. Microarray analysis was carried out on PND 0 lungs. RESULTS: Histologically, alveolar walls were thicker in lungs of PFOS-exposed newborns compared to controls. The ratio of solid tissue:small airway was increased, suggesting immaturity. Rescue studies were ineffective. Phospholipid concentrations and molecular speciation were unaffected by PFOS. No changes in markers of alveolar differentiation were detected by microarray analysis. CONCLUSIONS: Morphometric changes in lungs of PFOS exposed neonates were suggestive of immaturity, but the failure of rescue agents and normal pulmonary surfactant profile indicate that the labored respiration and mortality observed in PFOS-treated neonates was not due to lung immaturity.

Elemental mercury (Hg super(0)) poses a challenging flue gas control issue, and oxidized forms of mercury (Hg super(2+)) are of concern due to local deposition potential. In a previous study, mercury speciation, or more specifically oxidation of Hg super(0), was studied in simulated flue gases and in the presence of three-component model fly ashes. Gas-phase studies indicated that oxidation of Hg super(0) in the presence of hydrogen chloride (HCl) is rather slow, and proceeds at measurable rates only at temperatures >700 degree C and HCl concentrations in the range of 100-200 ppm. The effect of fly ash composition was investigated using a fixed-bed reactor containing different synthetic model fly ash components such as alumina (Al sub(2)O sub(3)), silica (SiO sub(2)), ferric oxide (Fe sub(2)O sub(3)), copper oxide (CuO), and calcium oxide (CaO). Transition metal oxides, CuO and Fe sub(2)O sub(3), exhibited significant catalytic activity in the surface-mediated oxidation of Hg super(0) in the presence of HCl. The observed Hg super(0) oxidation activities of the two oxides are possibly caused by the Deacon process in which chlorine gas (Cl sub(2)) is produced via catalytic oxidation of HCl over these two oxides. In the present follow-up study, the effect of sulfur dioxide (SO sub(2)) to HCl ratio on Hg super(0) oxidation was investigated. The addition of SO sub(2) to the moist flue gas at high SO sub(2):HCl ratios (10:1 to 4:1) caused a decrease in oxidation of Hg super(0). This is attributed to a scavenging effect of SO sub(2) and H sub(2)O on Cl sub(2). Addition of CaO to the synthetic fly ashes also caused a drop in Hg super(0) oxidation. It is possible that due to the partial removal of HCl by reaction with CaO less HCl is available for the catalytic Deacon reaction. The Hg super(0) oxidation activity of a cement kiln dust (CKD) sample collected from a full-scale hazardous waste incinerator was also studied. Qualitatively, it exhibited Hg super(0) oxidation catalytic behavior similar to that observed with CaO-containing model fly ashes. According to this study, only moderate oxidation of Hg super(0) (40%) can be expected in cement kilns burning hazardous waste. During hazardous and municipal waste combustion, the presence of sufficiently high HCl and/or Cl sub(2) in the gas phase may cause the metallic oxide compounds in the fly ash to be converted into metal chlorides. Additional tests were performed using synthetic fly ashes containing cuprous chloride (CuCl). These results were compared to those obtained using CuO. It was found that CuCl is so reactive that it oxidizes Hg super(0) even in the absence of HCl in the simulated flue gas. This is contrary to the behavior shown by CuO, which requires the presence of HCl in the flue gas in order for Hg super(0) oxidation to occur.

We used aerial photographs to quantify stream network expansion during the wet winter season in five agricultural catchments in western Oregon, USA. Winter stream drainage densities were nearly two orders of magnitude greater than summer stream densities, and agricultural land use was much more abundant along transient portions (e.g. swales, road ditches) of stream networks. Water moving from agricultural fields into expanded stream networks during large hydrologic events has the opportunity to bypass downstream riparian buffers along perennial streams and contribute nonpoint-source pollutants directly into perennial stream channels.

The hypothesis of this project was that emissions of hazardous air pollutants into the coastal urban atmosphere increased atmospheric depositional fluxes to proximate Great Waters. Areas of major field and modeling campaigns were located in southern Lake Michigan near Chicago, IL and northern Chesapeake Bay near Baltimore. The impact on Lake Michigan of PCB emissions from the urban area of Chicago was evaluated through field experiments to determine atmospheric concentrations, surface water concentrations, wet and dry deposition and bi-directional gas exchange. These values were used to construct a PCB mass budget for the Lake Michigan ecosystem, which includes the urban influence. PCB emissions in the Chicago atmosphere lead to dramatically increased atmospheric concentrations of PCBs off shore and significantly increased wet, dry particle and air-water exchange fluxes in southern Lake Michigan compared to the regional signal. High PCB concentrations occur over the lake only when the wind is from the direction of the urban/industrial complex inclusive of the shoreline from Gary, IN to Evanston, IL toward the lake. Although atmospheric loading of PCBs was much higher in the southern basin of Lake Michigan, water column concentrations have significantly decreased from 1980 to 1994 through the rapid uptake by settling particles, and have continued to decrease at a rate of 0.17 yr super(-1). In contrast to earlier PCB mass budgets that missed significant inputs, outputs and/or process terms, inclusion of the urban-influenced air-water exchange processes and a re-evaluation of new lake data effectively closed the PCB budget for Lake Michigan. Atmospheric exchange processes dominated the whole lake budget. The Chicago area, with high industrial density, emits large quantities of hazardous organic pollutants and has important impacts on the down wind coastal atmosphere and proximate surface waters.

A disadvantage of this process is that it spreads onroad emissions throughout a grid cell instead of along actual road locations. Recent air quality modeling in Portland, Oregon, using the CALPUFF dispersion model assigned emissions to specific roadway links. The resulting data were used to develop a regression model to approximate the CALPUFF predicted concentrations, determine the impacts of roadway proximity on ambient concentrations of three hazardous air pollutants, benzene, 1, 3-butadiene, and diesel PM, and to estimate the zone of influence around roadways. Independent variables in the model included emission rates and traffic volumes for individual roadway links, distance and direction between roadway links and receptors, and distributions of wind speeds and directions. Dependent variables were derived from simulated annual average pollutant concentrations from motor vehicles at modeled receptor locations, predicted using CALPUFF. The regression model had limited capability to predict CALPUFF concentrations with an R- squared value of about 0.6. The model indicated the zone of influence around a roadway as between 200 and 400 m. The results support the thesis that in order to capture localized impacts of hazardous air pollutants in a dispersion model, there is a need to include individual roadway links.

The geotropospheric transport of SVOCs varies according to the particle type. Two classes of SVOCs and two types of particles were analyzed to determine possible transport mechanisms to the troposphere: dicarboximide compounds moving from a soil matrix to the troposphere and polycyclic aromatic hydrocarbons (PAHs) from airborne particles to the troposphere. Both classes of compounds are considered to be SVOCs, since their vapor pressures under most environmental conditions range between 10 super(-2) to 10 super(-5) kP. The dicarboximide results were obtained from a laboratory chamber designed and used to determine the headspace flux of the dicarboximide fungicide, vinclozolin [3-(3,5-dichlorophenyl)-5-methyl-5-vinyl-oxzoli-dine-2,4-dione], and its three principal degradation products from chamber surfaces, sand, and sterilized and nonsterile North Carolina Piedmont aquic hapludult soils following dicarboximide applications. The PAH results were gathered from a high-volume air-sampling system used to measure particle and gas phase concentrations of SVOCs in the plume downwind from the World Trade Center fire. The comparison indicates that SVOC transport from the soil matrix can be influenced by the type and size of particles, their chemical composition, pH, oxygen, and microbial action. The study indicates that in the troposphere, molecular weight and structure are the principal factors affecting the geotropospheric flux of SVOCs from the particle to gas phase. Although experimentally determined equilibrium constants are more robust predictors of phase distribution in the troposphere (r super(2) = 0.81), published Henry's Law and vapor pressure constants also relate to particle-gas phase distribution (r super(2) = 0.73 and 0.72, respectively).
