AB This article presents research, criteria, framework, and guidance which were developed to provide recommendations for land use impact assessment specific to biofuels, but applicable to a variety of land uses. The criteria for land use modeling were developed along with a 10-step framework including a comprehensive ecosystem services valuation of scenarios. This research program is defined which includes the development of a user-friendly ecosystem services tool with accompanying default values and recommendations on input parameters which are necessary to develop the scenarios, integration curves, maps, and ecosystem profiles of each scenario. Based on these scenarios, curves, maps, and profiles, additional recommendations may be made on land use practices or regional selections. Finally, a discussion of implementation of the theory behind this methodology focuses on an analysis of biofuels.

AB Pollutant load reductions are often required to restore aquatic ecosystems experiencing eutrophication. Loads can be estimated using watershed models or data from monitoring stations, however data availability can limit the timeliness or comprehensiveness of the load estimates. We developed an approach to address this challenge that used watershed model results to estimate the proportion of annual nonpoint source nitrogen (N), phosphorus (P) and sediment (Sed) loads derived from unmonitored catchments. This proportion was multiplied by the nonpoint portion of United States Geological Survey (USGS) estimated annual river loads to account for annual variation in hydrologic conditions. Total loads were calculated as the sum of measured river loads, reported point sources from unmonitored areas and the estimated nonpoint source loads from unmonitored catchments. We applied this approach to the Chesapeake Bay because of its socio-economic and ecological importance. Median watershed loads for N, P and Sed were 140, 6.4 and 3030 Mg year(-1), respectively (1990-2004). Nonpoint source loads from the monitored areas constituted the greatest source of N, P and Sed (55, 47 and 74% respectively) to the Bay. The high N, P and Sed yield rates (7.3, 0.38 and 99 kg ha(-1) year(-1), respectively) from nonpoint loads originating from unmonitored areas near the Bay resulted in 25, 32 and 26% (N, P and Sed, respectively) of the Bay's total loads (excluding direct atmospheric deposition, shoreline erosion and oceanic inputs). Disproportionately high loads of P and Seds were associated with years that experienced elevated discharge whereas N loads were directly related to discharge. Error estimates indicated that our methods were most reliable for N (+/- 6%) but reasonable for P (+/- 22%) and provide an effective technique for the timely estimation of pollutant loads from watersheds with unmonitored catchments. Management strategies that decrease N deposition and reduce runoff to control P and Sed transport will effectively reduce pollutant loads. Published in 2010 by John Wiley & Sons, Ltd.

AB Response surface methodology was used to optimize spray drying process for producing biopesticide powders of Bacillus thuringiensis by using fermented broth of starch industry wastewater and wastewater sludge. Analysis of variance was carried out using number of viable spores in the powder as dependent variable. The determination coefficients of models were 92 and 94% for fermented broth of starch industry wastewater and wastewater sludge, respectively. Under the optimal conditions of the operational parameters of spray drying, the numbers of viable spores were 2.2 x 10(8) and 1.3 x 10(8) CFU/mg in the dry powders for starch industry wastewater and wastewater sludge respectively, with a loss of viable spores of 18 and 13% when compared with their respective fermented broths. The entomotoxicity (measured by the bioassay method) of the powders obtained under optimal conditions showed a loss of 28 and 18% when compared with the fermented broth of starch industry wastewater and wastewater sludge, respectively. The optimized results of spray drying were used for field application calculations. The volume of fermented broth required to produce powder formulated product when compared with the volume required for liquid formulation product in order to treat 1 ha of balsam fir was less and offered several advantages.

AB The presence of bis(2-ethylhexyl) phthalate (DEHP) and its metabolites, i.e. 2-ethylhexanol, 2-ethylhexanal, and 2-ethylhexanoic acid in wastewater sludge (WWS) were investigated during aerobic digestion and Bacillus thuringiensis (Bt)-based fermentation of WWS. Ultrasonication and Fenton oxidation pretreatment was applied to improve biodegradability of WWS and bioavailability of the target compounds for digestion and fermentation. DEHP and 2-ethylhexanoic acid were observed at higher concentration, meanwhile 2-ethylhexanol and 2-ethylhexanal were observed at lower concentration in WWS. After 20-day aerobic digestion, DEHP removal was 72%, 89%, and 85%, and 2-ethylhexanoic acid removal was 71%, 84%, 79%, respectively for raw, ultrasonicated, and Fenton-oxidized sludges. Bt was found to degrade DEHP, leading to DEHP removal of 21%, 40%, and 30%, respectively for raw, ultrasonicated, and Fenton-oxidized sludges in the fermentation. The results suggested that aerobic stabilization and Bt-based fermentation can remove the phthalates, and pre-treatment of WWS was also effective in improvement of DEHP biodegradation. Hence. Bt-based biopesticide production from WWS can be applied safely when taking into consideration the phthalate contaminants. (C) 2010 Elsevier Ltd. All rights reserved.

AB The Windsor, Ontario Exposure Assessment Study evaluated the contribution of ambient air pollutants to personal and indoor exposures of adults and asthmatic children living in Windsor, Ontario, Canada. In addition, the role of personal, indoor, and outdoor air pollution exposures upon asthmatic children's respiratory health was assessed. Several active and passive sampling methods were applied, or adapted, for personal, indoor, and outdoor residential monitoring of nitrogen dioxide, volatile organic compounds, particulate matter (PM; PM <= 2.5 mu m [PM(2.5)] and <= 10 mu m [PM(10)] in aerodynamic diameter), elemental carbon, ultrafine particles, ozone, air exchange rates, allergens in settled dust, and particulate-associated metals. Participants completed five consecutive days of monitoring during the winter and summer of 2005 and 2006. During 2006, in addition to undertaking the air pollution measurements, asthmatic children completed respiratory health measurements (including peak flow meter tests and exhaled breath condensate) and tracked respiratory symptoms in a diary. Extensive quality assurance and quality control steps were implemented, including the collocation of instruments at the National Air Pollution Surveillance site operated by Environment Canada and at the Michigan Department of Environmental Quality site in Allen Park, Detroit, MI. During field sampling, duplicate and blank samples were also completed and these data are reported. In total, 50 adults and 51 asthmatic children were recruited to participate, resulting in 922 participant days of data. When comparing the methods used in the study with standard reference methods, field blanks were low and bias was acceptable, with most methods being within 20% of reference methods. Duplicates were typically within less than 10% of each other, indicating that study results can be used with confidence. This paper covers study design, recruitment, methodology, time activity diary, surveys, and quality assurance and control results for the different methods used.

MORTALITY; OZONE; PHILADELPHIA; DISEASE; SYSTEM
AB Environmental epidemiology and more specifically time-series analysis have traditionally used area-averaged pollutant concentrations measured at central monitors as exposure surrogates to associate health outcomes with air pollution. However, spatial aggregation has been shown to contribute to the overall bias in the estimation of the exposure-response functions. This paper presents the benefit of adding features of the spatial variability of exposure by using concentration fields modeled with a chemistry transport model instead of monitor data and accounting for human activity patterns. On the basis of county-level census data for the city of Paris, France, and a Monte Carlo simulation, a simple activity model was developed accounting for the temporal variability between working and evening hours as well as during transit. By combining activity data with modeled concentrations, the downtown, suburban, and rural spatial patterns in exposure to nitrogen dioxide, ozone, and PM2.5 (particulate matter [PM] <= 10 mu m in aerodynamic diameter) were captured and parametrized. Exposures predicted with this model were used in a time-series study of the short-term effect of air pollution on total nonaccidental mortality for the 4-yr period from 2001 to 2004. It was shown that the time series of the exposure surrogates developed here are less correlated across co-pollutants than in the case of the area-averaged monitor data. This led to less biased exposure-response functions when all three co-pollutants were inserted simultaneously in the same regression model. This finding yields insight into pollutant-specific health effects that are otherwise masked by the high correlation among co-pollutants.

AB Nitrifying biofilters seeded with three different mixed-culture sources removed trichloromethane (TCM) and dibromochloromethane (DBCM) with removals reaching 18% for TCM and 75% for DBCM. In addition, resuspended biofilm removed TCM, bromodichloromethane (BDCM), DBCM, and tribromomethane (TBM) in backwash batch kinetic tests, demonstrating that the biofilters contained organisms capable of biotransforming the four regulated trihalomethanes (THMs) commonly found in treated drinking water. Upon the initial and subsequent increased TCM addition, total ammonia nitrogen (TOTNH(3)) removal decreased and then reestablished, indicating an adjustment by the biofilm bacteria. In addition, changes in DBCM removal indicated a change in activity related to DBCM. The backwash batch kinetic tests provided a useful tool to evaluate the biofilm's bacteria. Based on these experiments, the biofilters contained bacteria with similar THM removal kinetics to those seen in previous batch kinetic experiments. Overall, performance or selection does not seem based specifically on nutrients, source water, or source cultures and most likely results from THM product toxicity, and the use of GAC media appeared to offer benefits over anthracite for biofilter stability and long-term performance, although the reasons for this advantage are not apparent based on research to date.

AB Traditional environmental mould analysis is based on microscopic observations and counting of mould structures collected from the air on a sticky surface or culturing of moulds on growth media for identification and quantification. These approaches have significant limitations. A DNA-based method of mould analysis called mould specific quantitative PCR (MSQPCR) was created for more than 100 moulds. Based on a national sampling and analysis by MSQPCR of dust in US homes, a scale for comparing the mould burden in homes was created called the Environmental Relative Mouldiness Index (ERMI).90%. All influent samples were acutely toxic to Ceriodaphnia dubia and Pimephales promelas; toxicity was removed following treatment, except in the Luttrell Repository and Standard Mine BCR samples. Laboratory aeration of undiluted samples eliminated (Standard Mine BCR) or significantly reduced (Luttrell Repository, 65% survival) acute toxicity, most likely through removal of hydrogen sulfide. A toxicity identification evaluation suggested that metals also might be contributing to toxicity in the Luttrell Repository effluent samples; metals other than Mn were either not detected or very low (Fe and Pb) in the Standard Mine BCR samples. Field-aerated samples were not acutely toxic, and only the Luttrell Repository and Standard Mine samples showed short-term subchronic toxicity. Overall, results indicated BCR treatment had high metal removal efficiency and that inclusion of in-field aeration was beneficial in removal of acute and short-term subchronic toxicity. Environ.

AB Wastewater treatment plant (WWTP) effluents can contain estrogenic chemicals, which potentially disrupt fish reproduction and development. The current study focused on the use of an estrogen-responsive in vitro cell bioassay (T47D-KBluc), to quantify total estrogenicity of WWTP effluents. We tested a novel sample preparation method for the T47D-KBluc assay, using powdered media prepared with direct effluent. Results of the T47D-KBluc assay were compared with the induction of estrogen receptor regulated gene transcription in male fathead minnows (Pimephales promelas) exposed to the same effluents. Effluent samples for the paired studies were collected over the course of three months. According to the T47D-KBluc assay, the effluent estrogenicity ranged from 1.13 to 2.00 ng 17 beta-estradiol (E2) equivalents/L. Corresponding in vivo studies exposing male fathead minnows to 0, 10, 50, and 100% effluent dilutions demonstrated that exposure to 100% effluent significantly increased hepatic vitellogenin (VTG) and estrogen receptor a subunit transcripts relative to controls. The induction was also significant in males exposed to 250 ng E2/L or 100 ng E2/L. The in vitro and in vivo results support the conclusion that the effluent contains significant estrogenic activity, but there was a discrepancy between in vitro and in vivo based E2 equivalent estimates. Our results suggest that the direct effluent preparation method for the T47D-KBluc assay is a reasonable approach to estimate the estrogenicity of wastewater effluent. Environ. Toxicol.

AB Although laboratory toxicology tests are generally easy to perform, cost effective, and readily interpreted, they have been questioned for their environmental relevance. In contrast, field tests are considered realistic while producing results that are difficult to interpret and expensive to obtain. Toxicology tests were conducted on potatoes, peas, and soybeans grown in a native soil in pots in the greenhouse and were compared to plants grown outside under natural environmental conditions to determine toxicological differences between environments, whether different plant developmental stages were more sensitive to herbicides, and whether these species were good candidates for plant reproductive tests. The reproductive and vegetative endpoints of the greenhouse plants and field-grown plants were also compared. The herbicides bromoxynil, glyphosate, MCPA ([4-chloro-2-methylphenoxy] acetic acid), and sulfometuron-methyl were applied at below field application rates to potato plants at two developmental stages. Peas and soybeans were exposed to sulfometuron-methyl at similar rates at three developmental stages. The effective herbicide concentrations producing a 25% reduction in a given measure differed between experimental conditions but were generally within a single order of magnitude within a species, even though there were differences in plant morphology. This study demonstrated that potatoes, peas, and soybeans grown in pots in a greenhouse produce phytotoxicity results similar to those grown outside in pots; that reproductive endpoints in many cases were more sensitive than vegetative ones; and that potato and pea plants are reasonable candidates for asexual and sexual reproductive phytotoxicity tests, respectively. Plants grown in pots in a greenhouse and outside varied little in toxicity. However, extrapolating those toxicity results to native plant communities in the field is basically unknown and in need of research. Environ. Toxicol. Chem. 2011;30:455-468. (C) 2010 SETAC

AB The objectives of this study were to validate a relaxin and progesterone RIA for use in bottlenose dolphins, and quantify and characterize both hormones in extracts of placental tissue and serum collected during pregnancy and the post-partum period, and compare the results between dolphins with live and stillborn calves. In Experiment 1, validation of a heterologous relaxin and progesterone RIA involved specific displacement of antibody-bound radiolabeled human relaxin or progesterone in response to increasing volumes of pooled pregnant dolphin serum and amounts of respective hormone standards added to a fixed volume of serum. The displacement curves were considered parallel and additive relative to respective standard curves. In Experiment 2, immunoreactive relaxin and progesterone were detected in placental extracts and, in corresponding serum samples, concentrations of both hormones were higher during the pre-partum than post-partum periods. Circulatory concentrations of progesterone decreased (P < 0.05) from relatively high concentrations during early and mid-pregnancy to intermediate concentrations by late pregnancy (month effect, P < 0.0001) in dolphins with live births, whereas, in dolphins with stillbirths, the decrease in progesterone began earlier (month-by-birth status interaction, P < 0.007); mean concentrations were lower at mid- (37%, P < 0.06) and late (25%) pregnancy. Temporally, relaxin increased (P < 0.05) progressively from relatively low concentrations during early pregnancy to high concentrations during late pregnancy (month effect, P < 0.0001) and was not different between birth statuses (birth status effect. P = 0.76; month-by-birth status interaction, P = 0.17). Even though the interaction did not reach significance, mean relaxin concentrations were 42%, 29%, and 34% lower at early, mid-, and late pregnancy, respectively, in dolphins with stillbirths than in those with live births. In conclusion, the pregnancy-specific increase in serum concentrations of relaxin and lower concentrations of both relaxin and progesterone in association with stillbirths suggest the potential for relaxin to be used diagnostically to determine pregnancy status, and one or both hormones to be used to assess placental function, and, perhaps, fetal well-being in bottlenose dolphins and other cetaceans.

AB Saliva has an important advantage over serum as a medium for antibody detection due to noninvasive sampling, which is critical for community-based epidemiological surveys. The development of a Luminex multiplex immunoassay for measurement of salivary IgG and IgA responses to potentially waterborne pathogens, Helicobacter pylori, Toxoplasma gondii, Cryptosporidium, and four noroviruses, involved selection of antigens and optimization of antigen coupling to Luminex microspheres. Coupling confirmation was conducted using antigen specific antibody or control sera at serial dilutions. Dose response curves corresponding to different coupling conditions were compared using statistical tests. Control proteins in the specific antibody assay and a separate duplex assay for total immunoglobulins G and A were employed to assess antibody cross-reactivity and variability in saliva composition. 200 saliva samples prospectively collected from 20 adult volunteers and 10 paired sera from a subset of these volunteers were used to test this method. For chronic infections, H. pylori and T. gondii, individuals who tested IgG seropositive using commercial diagnostic ELISA also had the strongest salivary antibody responses in salivary antibody tests. A steep increase in antinorovirus salivary antibody response (immunoconversion) was observed after an episode of acute diarrhea and vomiting in a volunteer. The Luminex assay also detected seroconversions to Cryptosporidium using control sera from infected children. Ongoing efforts involve further verification of salivary antibody tests and their application in larger pilot community studies. Published by Elsevier B.V.

AB The (18)O and (2)H (HDO) compositions are summarized for sampled springs (n = 81) within the Elwha watershed (a parts per thousand 692 km(2)) on the northern Olympic Peninsula. Samples, collected during 2001-2009, of springs (n = 158), precipitation (n = 520), streams (n = 176), and firn (n = 3) assisted the determinations for meteoric composition of recharge waters. The local mean water line (LMWL) is defined as delta(2)H = 8.2 delta(18)O - 9.3 for the watershed. Recharge history is surmised from groundwater ages ranging from 5 +/- A 3 years (apparent (85)Kr) to 9,490 +/- A 420 (14)C cal years BP. About 56% of the springs were recharged over the last 1,000 years while 13% of springs were recharged over 5,000 years ago. Spring HDO values fluctuate between -11.8 to -15.6aEuro degrees delta(18)O and -90.9 to -119.4aEuro degrees delta(2)H. Deuterium excess values predominate around 4-6aEuro degrees. The HDO proxy records from springs suggest a pronounced paleoclimate shift in air masses near 5,000 year BP on the Peninsula.

AB Recently, investigators demonstrated associations between fine particulate matter (PM)-associated metals and adverse health effects. Residual oil fly ash (ROFA), a waste product of fossil fuel combustion from boilers, is rich in the transition metals Fe, Ni, and V, and when released as a fugitive particle, is an important contributor to ambient fine particulate air pollution. We hypothesized that a single-inhalation exposure to transition metal-rich PM will cause concentration-dependent cardiovascular toxicity in spontaneously hypertensive (SH) rats. Rats implanted with telemeters to monitor heart rate and electrocardiogram were exposed once by nose-only inhalation for 4 hours to 3.5 mg/m(3), 1.0 mg/m(3), or 0.45 mg/m(3) of a synthetic PM (dried salt solution), similar in composition to a well-studied ROFA sample consisting of Fe, Ni, and V. Exposure to the highest concentration of PM decreased T-wave amplitude and area, caused ST depression, reduced heart rate (HR), and increased non-conducted P-wave arrhythmias. These changes were accompanied by increased pulmonary inflammation, lung resistance, and vagal tone, as indicated by changes in markers of HR variability (increased root of the mean of squared differences of adjacent RR intervals [RMSSD], low frequency [LF], high frequency [HF], and decreased LF/HF), and attenuated myocardial micro-RNA (RNA segments that suppress translation by targeting messenger RNA) expression. The low and intermediate concentrations of PM had less effect on the inflammatory, HR variability, and micro-RNA endpoints, but still caused significant reductions in HR. In addition, the intermediate concentration caused ST depression and increased QRS area, whereas the low concentration increased the T-wave parameters. Thus, PM-induced cardiac dysfunction is mediated by multiple mechanisms that may be dependent on PM concentration and myocardial vulnerability (this abstract does not reflect the policy of the United States Environmental Protection Agency).

AB This study is an assessment of the impact of reduced stationary source NOx emissions on ground-level concentrations of ozone (O-3) and dry-NO3 (HNO3(g) + NO3(p)-) in the eastern United States (EUS). Total anthropogenic NOx and VOC emissions have declined 32% and 20%, respectively, from 1997 to 2005 in the 20 eastern states participating in a NOx Budget Trading Program (NBP). Annual and ozone season (OS) NOx emissions from electric generating units (EGUs) have declined 48% and 66%, respectively, in the EUS.
From 1997-1999 to 2006-2008 measured decline in meteorologically adjusted (met-adj) daily maximum 8-h (dm8h) O-3, has been 8 ppb or 14% for the EUS during the May-September OS, with the largest declines occurring in the highest concentration category (99th percentile). Random coefficient models, with NBP and Acid Rain Program (ARP) regulated NOx emissions as the independent variable, show highly significant relations (p <= 0.0001) to dm8h O-3 for 1997-2008 during the OS. Regional declines within the EUS range from 11% to 16%. The patterns of the O-3 trends are in general agreement with other recent studies. Rural and urban sites both show similar levels of decline from pre- to post-NBP periods.
Dry-NO3 during the OS shows a substantial decline from 3.1 to 1.8 mu g NO3 m(-3). Random coefficient models show regional results ranging from 32% to 39% declines, and measured results show a 35-46% decline in dry-NO3 from 1997-1999 to 2006-2008. These results suggest that regulating NOx emissions has been highly effective in reducing both ozone and dry-NO3 concentrations during the OS.
Overall, a 32% reduction in total annual anthropogenic NOx emissions from 1997 to 2005 has been accompanied by a 7-8 ppb, or 12-13% decline in OS dm8h O-3 concentration, and a 34% decline in dry-NO3 concentration in the 20-state NBP region. Model results indicate a 50% further reduction in NBP regulated NOx emissions will reduce O-3 concentrations an additional 3-5% and dry-NO3 concentrations by 13-16%. (C) 2010 Elsevier Ltd.

AB Carbonaceous aerosol is one of the important constituents of fine particulate matter (PM(2.5)) in southern China, including the Pearl River Delta (PRD) region and Hong Kong (HK). During the study period (October and December of 2002, and March and June of 2003), the monthly average organic carbon (OC) ranged from 3.52 to 7.87 mu g m(-3) in Hong Kong and 4.14-20.19 mu g m(-3) in the PRD from simultaneous measurements at three sites in HK and four sites in the PRO. Compared to the PRD, the spatial distribution of carbonaceous aerosol in Hong Kong was relatively homogeneous. Sources contributing to excess OC in the PRO were examined, which is the difference between OC concentrations measured at the PRD sites to the average level in Hong Kong. Eight primary sources contributing to excess OC were identified with chemical mass balance modeling in a combination with molecular markers analyzed by gas chromatography/mass spectrometry. Excess OC at Guangzhou, the capital city of Guangdong province, was consistently high, ranging from 9.77 to 13.6 mu g m(-3). Four primary sources including gasoline engine exhaust, diesel engine exhaust, biomass burning, and coal combustion accounted for more than 50% of excess OC in the PRD, especially in December (up to 76%). Mobile source emissions alone can contribute about 30% of excess OC. The unexplained or other excess OC was the highest at the rural site, but in general less than 20% at other sites. The coal combustion source contribution was unique in that it exhibited relatively homogeneous spatial distribution, indicating it was still an important source of carbonaceous aerosol in the PRO (17% of excess OC) during the study period. This analysis revealed that primary emissions are important sources of excess OC in the PRD and there is a need to reduce the emissions of mobile sources, biomass burning, and coal combustion in order to improve air quality in southern China.

AB Workshops on maternal toxicity were held at the annual Society of Toxicology, Teratology Society, and European Teratology Society meetings in 2009. Speakers presented background information prior to a general discussion on this topic.
The following recommendations/options are based on the outcome of the discussions at the workshops:
1. A comprehensive evaluation of all available data from general toxicity studies, range-finding Developmental and Reproductive Toxicology (DART) studies, class effects, structure-activity relationships, exposure studies, etc. is essential for appropriate dose selection for definitive DART studies. The intent is to avoid marked maternal toxicity leading to mortality or decreased body weight gains of greater than 20% for prolonged periods.
(a) Evaluate alternative endpoints for dose selection and data interpretation (e.g., target tissue effects and pharmacology) for biotherapeutics.
(b) Evaluate additional maternal parameters based on effects and/or target organs observed in short-term (e.g., 2- or 4-week) general toxicity studies. 2. Evaluate all available data to determine a cause-effect relationship for developmental toxicity.
(a) Conduct a pair-feeding/pair-watering study as a follow-up.
(b) Evaluate individual data demonstrating maternal toxicity in the mother with adverse embryo-fetal outcomes in the litter associated with the affected mother.
(c) Conduct single-dose studies at increasing doses as a complement to conventional embryo-fetal toxicity studies for certain classes of compounds that affect the hERG channel. 3. Support statements that embryo-fetal effects are caused by maternal toxicity and/or exaggerated pharmacology, especially for malformations.
(a) Provide mechanistic or other supporting data.
(b) Establish the relevance of the DART findings in animals for human exposures. Birth Defects Res (Part B) 92:36-51, 2011. (C) 2010 Wiley-Liss, Inc.

AB Research on the environmental fate and transport of PCBs in Lake Ontario basin depends, among other aspects, on the availability of representative data sets for upstream sources, but data are lacking for most US Lake Ontario tributaries. In this study, water samples were collected between September 2004 and October 2008 from five tributaries and were analyzed for 209 polychlorinated biphenyls (PCB) with high-resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS) following EPA Method 1668A. Total PCB concentrations ranged between 0.31 and 42.75 ng L(-1). Congeners between Di and Hexa PCBs accounted between 70 and 99% of the total PCB. The tributary with highest PCB concentrations presented similar pattern and percentage levels to Aroclor 1242. Total average loads for the sampling events ranged between 1.85 g d(-1) and 59.08 g d(-1). PCB concentrations were evaluated against other variables and other studies (including different matrices) to better understand their transport. The methodology used is reliable to assess PCB contamination in surface water. Published by Elsevier Ltd.

TI A quantitative approach to combine sources in stable isotope mixing
models
SO ECOSPHERE
LA English
DT Article
DE Bayesian analysis; diet; mixing model; source partitioning; stable
isotope
AB Stable isotope mixing models, used to estimate source contributions to a mixture, typically yield highly uncertain estimates when there are many sources and relatively few isotope elements. Previously, ecologists have either accepted the uncertain contribution estimates for individual sources or addressed the problem in an ad hoc way by combining either related sources prior to analysis or the estimated proportions of related sources following analysis. Neither of these latter approaches explicitly account for uncertainty in source combinations within the likelihood framework. In this paper we incorporate uncertainty in both the number of source groups and group assignment within a formal Bayesian mixing model framework. By dynamically exploring model complexity due to aggregating sources based on shared proportional contributions, we can estimate posterior probabilities of alternative group configurations, and construct posterior dendrograms of group membership. We apply this method to simulated data, and illustrate applications to two consumer datasets (rainbow trout, coastal mink). Our results demonstrate that estimating, rather than fixing, the number of proportional contributions in a mixing model can improve model inference and reduce bias in estimates of source contributions to a mixture.

AB There is an expanding body of evidence that free-living amoebae (FLA) increase both the numbers and virulence of water-based, human-pathogenic, amoeba-resisting microorganisms (ARM). Legionella spp., Mycobacterium spp., and other opportunistic human pathogens are known to be both ARM and also the etiologic agents of potentially fatal human lung infections. However, comparatively little is known about the FLA that may facilitate ARM growth in drinking water. This review examines the available literature on FLA in treated drinking water systems; in total 26 studies from 18 different countries. FLA were reported to breakthrough the water treatment barrier and enter distribution systems, in addition to the expected post-treatment system ingress. Once in the distribution system there is evidence of FLA colonization and regrowth especially in reservoirs and in-premise plumbing storage tanks. At the point of use the average FLA detection rate was 45% but highly variable (n = 16, sigma = 31) due to both differences in both assay methods and the type of water systems examined. This review reveals that FLA are consistently detected in treated drinking water systems around the world and present a yet unquantified emerging health risk. However, more research is urgently required before accurate risks assessments can be undertaken to assess the impacts on human health, in households and institutions, due to exposure to FLA facilitated pathogenic ARM.

AB Over the last decade, the environmental sciences have witnessed an incredible movement towards the utilization of high-throughput molecular tools that are capable of detecting simultaneous changes of hundreds, and even thousands, of molecules and molecular components after exposure of organisms to different environmental stressors. These techniques have received a great deal of attention because they not only offer the potential to unravel novel mechanisms of physiological and toxic action but are also amenable to the discovery of biomarkers of exposure and effects. In this article, we review the state of knowledge of one of these tools in ecotoxicological research: proteomics. We summarize the state of proteomics research in fish, and follow with studies conducted with aquatic invertebrates. A brief discussion on proteomic methods is also presented. We conclude with some ideas for future proteomic studies with fish and aquatic invertebrates. Environ. Toxicol. Chem. 2011;30:274-282. (C) 2010 SETAC

AB Bifunctional ligands containing an ester linkage between morphine and the delta-selective pharmacophore Dmt-Tic were synthesized, and their binding affinity and functional bioactivity at the mu, delta and kappa opioid receptors determined. Bifunctional ligands containing or not a spacer of beta-alanine between the two pharmacophores lose the mu agonism deriving from morphine becoming partial p agonists mu or mu antagonists 5. Partial kappa agonism is evidenced only for compound 4. Finally, both compounds showed potent delta antagonism. (C) 2010 Elsevier Masson SAS. All rights reserved.

AB Cytochrome P-450 (CYP)-derived epoxyeicosatrienoic acids (EETs) possess potent anti-inflammatory effects in vitro. However, the effect of increased CYP-mediated EET biosynthesis and decreased soluble epoxide hydrolase (sEH, Ephx2)-mediated EET hydrolysis on vascular inflammation in vivo has not been rigorously investigated. Consequently, we characterized acute vascular inflammatory responses to endotoxin in transgenic mice with endothelial expression of the human CYP2J2 and CYP2C8 epoxygenases and mice with targeted disruption of Ephx2. Compared to wild-type controls, CYP2J2 transgenic, CYP2C8 transgenic, and Ephx2(-/-) mice each exhibited a significant attenuation of endotoxin-induced activation of nuclear factor (NF)-kappa B signaling, cellular adhesion molecule, chemokine and cytokine expression, and neutrophil infiltration in lung in vivo. Furthermore, attenuation of endotoxin-induced NF-kappa B activation and cellular adhesion molecule and chemokine expression was observed in primary pulmonary endothelial cells isolated from CYP2J2 and CYP2C8 transgenic mice. This attenuation was inhibited by a putative EET receptor antagonist and CYP epoxygenase inhibitor, directly implicating CYP epoxygenase-derived EETs with the observed anti-inflammatory phenotype. Collectively, these data demonstrate that potentiation of the CYP epoxygenase pathway by either increased endothelial EET biosynthesis or globally decreased EET hydrolysis attenuates NF-kappa B-dependent vascular inflammatory responses in vivo and may serve as a viable anti-inflammatory therapeutic strategy.-Deng, Y., Edin, M.

AB Stachybotrys is a hydrophilic fungal genus that is well known for its ability to colonize water-damaged building materials in indoor environments. Personal exposure to Stachybotrys chartarum allergens, mycotoxins, cytolytic peptides, and other immunostimulatory macromolecules has been proposed to exacerbate respiratory morbidity. To date, advances in Stachybotrys detection have focused on the identification of unique biomarkers that can be detected in human serum; however, the availability of immunodiagnostic reagents to Stachybotrys species have been limited. In this study, we report the initial characterization of monoclonal antibodies (MAbs) against a semi-purified cytolytic S. chlorohalonata preparation (cScp) derived from hyphae. BALB/c mice were immunized with cScp and hybridomas were screened against the cScp using an antigen-mediated indirect ELISA. Eight immunoglobulin M MAbs were produced and four were specifically identified in the capture ELISA to react with the cScp. Cross-reactivity of the MAbs was tested against crude hyphal extracts derived from 15 Stachybotrys isolates representing nine Stachybotrys species as well as 39 other environmentally abundant fungi using a capture ELISA. MAb reactivity to spore and hyphal antigens was also tested by a capture ELISA and by fluorescent halogen immunoassay (fHIA). ELISA analysis demonstrated that all MAbs strongly reacted with extracts of S. chartarum but not with extracts of 39 other fungi. However, four MAbs showed cross-reactivity to the phylogenetically related genus Memnoniella. fHIA analysis confirmed that greatest MAb reactivity was ultrastructurally localized in hyphae and phialides. The results of this study further demonstrate the feasibility of specific MAb-based immunoassays for the detection of S. chartarum.

AB Pulmonary toxicity induced by asbestos is thought to be mediated through redox-cycling of fiber-bound and bioavailable iron (Fe). We hypothesized that Libby amphibole (LA)-induced cute lung injury will be exacerbated in rat models of cardiovascular disease (CVD)-associated Fe-overload and oxidative stress. Healthy male Wistar Kyoto (WKY), spontaneously hypertensive (SH) and SH heart failure (SHHF) rats were intratracheally instilled with 0.0, 0.25 or 1.0 mg/rat LA and examined at 1 day, 1 week or 1 month. Although histologically it was not possible to distinguish severity differences between strains in LA-induced initial inflammation and later fibrosis, quantitative assessment of biomarkers showed strain-related differences. LA-induced neutrophilic inflammation was reversible in WKY but persisted more in SH and SHHF. Lung MIP-2 mRNA increased only in WKY at 1 day in response to LA but not in SH and SHHF. Bronchoalveolar lavage fluid (BALF) protein increased in SH but not WKY at 1 week and 1 month, while.-glutamyltransferase and N-acetyl-beta-D-glucosaminidase activities increased in all strains (WKY > SH=SHHF). BALF ferritin levels were high at baseline and increased following LA exposure only in SH and SHHF. Ferritin heavy chain mRNA increased only in SHHF at 1 day. At 1 month ferritin light chain mRNA declined from already high baseline levels in SHHF but increased in WKY and SH suggesting its differential involvement in LA-induced injury in Fe-overload. Unlike WKY, both SHHF and SH failed to increase the lung lining antioxidant, ascorbate, in response to LA. We conclude that underlying CVD-associated Fe-overload is likely linked to persistent lung injury, inflammation and antioxidant decompensation following LA exposure in rats.

AB To bridge the gaps between traditional mesoscale modelling and microscale modelling, the National Center for Atmospheric Research, in collaboration with other agencies and research groups, has developed an integrated urban modelling system coupled to the weather research and forecasting (WRF) model as a community tool to address urban environmental issues. The core of this WRF/urban modelling system consists of the following: (1) three methods with different degrees of freedom to parameterize urban surface processes, ranging from a simple bulk parameterization to a sophisticated multi-layer urban canopy model with an indoor-outdoor exchange sub-model that directly interacts with the atmospheric boundary layer, (2) coupling to fine-scale computational fluid dynamic Reynolds-averaged Navier-Stokes and Large-Eddy simulation models for transport and dispersion (T&D) applications, (3) procedures to incorporate high-resolution urban land use, building morphology, and anthropogenic heating data using the National Urban Database and Access Portal Tool (NUDAPT), and (4) an urbanized high-resolution land data assimilation system. This paper provides an overview of this modelling system; addresses the daunting challenges of initializing the coupled WRF/urban model and of specifying the potentially vast number of parameters required to execute the WRF/urban model; explores the model sensitivity to these urban parameters; and evaluates the ability of WRF/urban to capture urban heat islands, complex boundary-layer structures aloft, and urban plume T&D for several major metropolitan regions. Recent applications of this modelling system illustrate its promising utility, as a regional climate-modelling tool, to investigate impacts of future urbanization on regional meteorological conditions and on air quality under future climate change scenarios.

AB Human immunodeficiency virus (HIV)-associated infection involves the entry of virus-bearing monocytes into the brain, followed by microglial activation, neuroinflammation, and upregulated arachidonic acid (AA) metabolism. The HIV-1 transgenic (Tg) rat, a noninfectious HIV-1 model, shows neurologic and behavioral abnormalities after 5 months of age. We hypothesized that brain AA metabolism would be elevated in older HIV-1 Tg rats in vivo. Arachidonic acid incorporation from the plasma into the brain of unanesthetized 7-to-9-month-old rats was imaged using quantitative autoradiography, after [1-C-14] AA infusion. Brain phospholipase (PLA(2)) activities and eicosanoid concentrations were measured, and enzymes were localized by immunostaining. AA incorporation coefficients k* and rates J(in), measures of AA metabolism, were significantly higher in 69 of 81 brain regions in HIV-1 Tg than in control rats, as were activities of cytosolic (c) PLA(2)-IV, secretory (s)PLA(2), and calcium independent (i) PLA(2)-VI, as well as prostaglandin E-2 and leukotriene B-4 concentrations. Immunostaining of somatosensory cortex showed elevated cPLA(2)-IV, sPLA(2)-IIA, and cyclooxygenase-2 in neurons. Brain AA incorporation and other markers of AA metabolism are upregulated in HIV-1 Tg rats, in which neurologic changes and neuroinflammation have been reported. Positron emission tomography with [1-C-11] AA could be used to test whether brain AA metabolism is upregulated in HIV-1-infected patients, in relation to cognitive and behavioral disturbances.

AB Objective: Guillain-Barre Syndrome (GBS) is the leading cause of acute peripheral neuropathy worldwide, often associated with recent foodborne infection with Campylobacter jejuni. In this cross-sectional analysis of data from the Agricultural Health Study, we tested whether swine and poultry exposure were associated with increased prevalence of GBS-like neurologic symptoms. Methods: Using multivariate analysis, we tested the symptoms such as numbness and weakness, relevant to inflammatory peripheral neuropathies, among farmers with self-reported occupational poultry or swine exposure compared with farmers who reported no occupational animal exposure. Results: Among swine farmers/workers, prevalence of weakness and numbness were increased (P < 0.05). Among poultry farmers/workers, prevalence of weakness and numbness were increased, but increased prevalence of weakness was not statistically significant. Conclusions: Occupational contact with live poultry or swine, potentially related to C. jejuni exposure, was associated with increased reporting of GBS-like symptoms.

TI Optimal Pollution Trading Without Pollution Reductions: A Note
SO JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION
LA English
DT Article
DE water quality trading; flow pollution; wetlands; trading ratio
ID WATER-QUALITY; WETLANDS; BASIN; HABITAT
AB Various kinds of water pollution occur in pulses (e.g., agricultural and urban runoff). Ecosystems, such as wetlands, can serve to regulate these pulses and smooth pollution distributions over time. This smoothing reduces total environmental damages when "instantaneous" damages are marginally increasing. This paper introduces a water quality trading model between a farm (a pulse-pollution source) and a firm (a more steady pollution source) where the object of exchange is the "temporary" retention of runoff as opposed to total runoff reductions. The optimal trading ratio requires firm emissions to be offset by more than a proportional retention of the initial agricultural runoff pulse. The reason is twofold: (1) emissions are steady or constant over time and, in this sense, have relatively larger environmental impact; and (2) certain kinds of runoff management cause delayed environmental damages.

AB Verapamil has been shown to be neuroprotective in several acute neurotoxicity models due to blockade of calcium entry into neurons. However, the potential use of veraparnil to treat chronic neurodegenerative diseases has not been reported. Using rat primary mesencephalic neuron/glia cultures, we report that verapamil significantly inhibited LPS-induced dopaminergic neurotoxicity in both pre- and post-treatment experiments. Reconstituted culture studies revealed that the presence of microglia was essential in verapamil-elicited neuroprotection. Mechanistic studies showed that decreased production of inflammatory mediators from LPS-stimulated microglia underlay neuroprotective property of verapamil. Further studies demonstrated that microglial NADPH oxidase (PHOX), the key superoxide-producing enzyme, but not calcium channel in neurons, is the site of action for the neuroprotective effect of verapamil. This conclusion was supported by the following two observations: 1) Verapamil failed to show protective effect on LPS-induced dopaminergic neurotoxicity in PHOX-deficient (deficient in the catalytic subunit of gp91(phox)) neuron/glia cultures: 2) Ligand binding studies showed that the binding of [H-3]Verapamil onto gp91(phox) transfected COS7 cell membranes was higher than the non-transfected control. The calcium channel-independent neuroprotective property of verapamil was further supported by the finding that R(+)-verapamil, a less active form in blocking calcium channel, showed the same potency in neuroprotection, inhibition of pro-inflammatory factors production and binding capacity to gp91(phox) membranes as R(-)-verapamil, the active isomer of calcium channel blocker. In conclusion, our results demonstrate a new indication of verapamil-mediated neuroprotection through a calcium channel-independent pathway and provide a valuable avenue for the development of therapy for inflammation-related neurodegenerative diseases.

ID ICCVAM EVALUATION; CLASSIFICATION
AB The original Organisation for Economic Co-operation and Development Test Guideline 429 (OECD TG 429) for the murine local lymph node assay (LLNA) required five mice/group if mice were processed individually. We used data from 83 LLNA tests (275 treated groups) to determine the impact on the LLNA outcome of reducing the group size from five to four. From DPM measurements, we formed all possible four- and five-mice combinations for the treated and control groups. Stimulation index (SI) values from each four-mice combination were compared with those from five-mice combinations, and agreement (both SI <3 or both SI >= 3) determined. Average agreement between group sizes was 97.5% for the 275 treated groups. Compared test-by-test, 90% (75/83) of the tests had 100% agreement: agreement was 83% for the remaining eight tests. Disagreement was due primarily to variability in animal responses and closeness of the SI to three (positive response threshold) rather than to group size reduction. We conclude that using four rather than five mice per group would reduce animal use by 20% without adversely impacting LLNA performance. This analysis supported the recent update to OECD TG 429 allowing a minimum of four mice/group when each mouse is processed individually. Published by Elsevier Inc.

AB Atrazine (2-chloro-4-ethylamino-6-isopropylamino-s-triazine) was introduced in the 1950s as a broad spectrum herbicide, and remains one of the most widely used herbicides in the United States. Several studies have suggested that atrazine modifies steroidogenesis and may disrupt reproductive function and development in a variety of species. A primary concern has been whether atrazine increases the synthesis of estrogens, perhaps by enhancing aromatase gene expression and activity. In this study, the effect of atrazine was compared in cultures using primary granulosa cells and H295R adrenal cortical carcinoma cells. Atrazine (10 mu M), but not its metabolite, 2-chloro-4.6-diamino-1,15-triazine (DACT), significantly increased estradiol production and aromatase activity in granulosa cell cultures only when measured for 1-h following 24h of exposure. In H295R cells, atrazine (10 mu M) increased estradiol and estrone production. Importantly, atrazine (10 mu M) increased progesterone production from both cell types suggesting a broader effect of atrazine on steroidogenesis. Published by Elsevier Inc.

AB This paper provides recommendations on experimental design for early-tier laboratory studies used in risk assessments to evaluate potential adverse impacts of arthropod-resistant genetically engineered (GE) plants on non-target arthropods (NTAs). While we rely heavily on the currently used proteins from Bacillus thuringiensis (Bt) in this discussion, the concepts apply to other arthropod-active proteins. A risk may exist if the newly acquired trait of the GE plant has adverse effects on NTAs when they are exposed to the arthropod-active protein. Typically, the risk assessment follows a tiered approach that starts with laboratory studies under worst-case exposure conditions; such studies have a high ability to detect adverse effects on non-target species. Clear guidance on how such data are produced in laboratory studies assists the product developers and risk assessors. The studies should be reproducible and test clearly defined risk hypotheses. These properties contribute to the robustness of, and confidence in, environmental risk assessments for GE plants. Data from NTA studies, collected during the analysis phase of an environmental risk assessment, are critical to the outcome of the assessment and ultimately the decision taken by regulatory authorities on the release of a GE plant. Confidence in the results of early-tier laboratory studies is a precondition for the acceptance of data across regulatory jurisdictions and should encourage agencies to share useful information and thus avoid redundant testing.

AB The studies presented in this manuscript focus on characterization of transcriptomic responses to anti-androgens in zebrafish (Danio rerio). Research on the effects of anti-androgens in fish has been characterized by a heavy reliance on apical endpoints, and molecular mechanisms of action (MOA) of anti-androgens remain poorly elucidated. In the present study, we examined effects of a short term exposure (24-96 h) to the androgen receptor antagonists flutamide (FLU) and vinclozolin (VZ) on gene expression in gonads of sexually mature zebrafish, using commercially available zebrafish oligonucleotide microarrays (4 x 44K platform). We found that VZ and FLU potentially impact reproductive processes via multiple pathways related to steroidogenesis, spermatogenesis, and fertilization. Observed changes in gene expression often were shared by VZ and FLU, as demonstrated by overlap in differentially-expressed genes and enrichment of several common key pathways including: (1) integrin and actin signaling, (2) nuclear receptor 5A1 signaling, (3) fibroblast growth factor receptor signaling, (4) polyamine synthesis, and (5) androgen synthesis. This information should prove useful to elucidating specific mechanisms of reproductive effects of anti-androgens in fish, as well as developing biomarkers for this important class of endocrine-active chemicals.

TI Internal standards: A source of analytical bias for volatile organic
analyte determinations

DE Volatile organic compounds; Internal standards; Bias; Biota; Soil;
Water; Analyses
ID SAMPLES; ERROR
AB The use of internal standards in the determination of volatile organic compounds as described in SW-846 Method 8260C introduces a potential for bias in results once the internal standards (ISTDs) are added to a sample for analysis. The bias is relative to the dissimilarity between the analyte and internal standard physical properties that influence how easily analytes are separated from a matrix and concentrated during analysis.
Method 5032 is a vacuum distillation procedure for extracting analytes from a sample for use with Method 8260C. Vacuum distillation is also incorporated within another GC/MS analytical procedure, Method 8261A. Method 8260C/5032 and Method 8261A are experimentally identical, however, Method 8261A uses internal standards differently by relating the recovery of each compound to its boiling point and relative volatility. By processing each analysis (water, soil, and biota) using both Method 8260C and Method 8261A, the two approaches are compared on the basis of analyte bias and the failure rate of the quality controls.
Analytes were grouped by how similar their boiling points and natural log of their relative volatilities (In RVs) were to their Method 8260C recommended ISTDs. For the most similar analytes, the Method 8260C determinations yielded an average bias less than 10% and a failure to meet calibration criteria less than 7%. However, as the difference between analyte and ISTD became greater the bias increased to over 40% (matrix dependent) and its calibration failure rate approached 70%. In comparison, when the Method 8260C data were reprocessed as Method 8261A determinations, this trend for groupings was minimized with biases increasing from 6% to only 20% and the calibration failure rate went from 0% to 15%.

AB Background: Concerns over the health effects of nanomaterials in the environment have created a need for microscopy methods capable of examining the biological interactions of nanoparticles (NP). Unfortunately, NP are beyond the diffraction limit of resolution for conventional light microscopy (similar to 200 nm). Fluorescence and electron microscopy techniques commonly used to examine NP interactions with biological substrates have drawbacks that limit their usefulness in toxicological investigation of NP. EM is labor intensive and slow, while fluorescence carries the risk of photobleaching the sample and has size resolution limits. In addition, many relevant particles lack intrinsic fluorescence and therefore can not be detected in this manner. To surmount these limitations, we evaluated the potential of a novel combination of darkfield and confocal laser scanning microscopy (DF-CLSM) for the efficient 3D detection of NP in human lung cells. The DF-CLSM approach utilizes the contrast enhancements of darkfield microscopy to detect objects below the diffraction limit of 200 nm based on their light scattering properties and interfaces it with the power of confocal microscopy to resolve objects in the z-plane.
Results: Validation of the DF-CLSM method using fluorescent polystyrene beads demonstrated spatial colocalization of particle fluorescence (Confocal) and scattered transmitted light (Darkfield) along the X, Y, and Z axes. DF-CLSM imaging was able to detect and provide reasonable spatial locations of 27 nm TiO2 particles in relation to the stained nuclei of exposed BEAS 2B cells. Statistical analysis of particle proximity to cellular nuclei determined a significant difference between 5 min and 2 hr particle exposures suggesting a time-dependant internalization process.
Conclusions: DF-CLSM microscopy is an alternative to current conventional light and electron microscopy methods that does not rely on particle fluorescence or contrast in electron density. DF-CLSM is especially well suited to the task of establishing the spatial localization of nanoparticles within cells, a critical topic in nanotoxicology. This technique has advantages to 2D darkfield microscopy as it visualizes nanoparticles in 3D using confocal microscopy. Use of this technique should aid toxicological studies related to observation of NP interactions with biological endpoints at cellular and subcellular levels.

AB Pesticides are nearly ubiquitous in surface waters of the United States, where they often are found as mixtures. The molecular mechanisms underlying the toxic effects of sub-lethal exposure to pesticides as both individual and mixtures are unclear. The current work aims to identify and compare differentially expressed proteins in brains of male fathead minnows (Pimephales promelas) exposed for 72 h to permethrin (7.5 mu g/L), terbufos (57.5 mu g/L) and a binary mixture of both. Twenty-four proteins were found to be differentially expressed among all three treatments relative to the control using an ANOVA followed by a Dunnett's post hoc test (p <= 0.05). One protein was found to be differentially expressed among all treatment groups and one protein was in common between the terbufos and the mixture group. Fifteen spots were successfully sequenced using LC-MS/MS sequencing. Proteins associated with the ubiquitin-proteasome system, glycolysis, the cytoskeleton and hypoxia were enriched. As a second objective, we attempted to establish protein expression signatures (PES) for individual permethrin and terbufos exposures. We were unable to generate a useable PES for terbufos; however, the permethrin PES was able to distinguish between control and permethrin-exposed individuals in an independent experiment with an accuracy of 87.5%. This PES also accurately classified permethrin exposed individuals when the exposure occurred as part of a mixture. The identification of proteins differentially expressed as a result of pesticide exposure represent a step forward in the understanding of mechanisms of toxicity of permethrin and terbufos. They also allow a comparison of molecular responses of the binary mixture to single exposures. The permethrin PES is the first step in establishing a method to determine exposures in real-world scenarios. Published by Elsevier B.V.

TI Legacy and Fate of Mercury and Methylmercury in the Florida Everglades
SO ENVIRONMENTAL SCIENCE & TECHNOLOGY
LA English
DT Article
ID PERIPHYTON; PEAT
AB Mass inventories of total Hg (THg) and methylmercury (MeHg) and mass budgets of Hg newly deposited during the 2005 dry and wet seasons were constructed for the Everglades. As a sink for Hg, the Everglades has accumulated 914, 1138, 4931, and 7602 kg of legacy THg in its 4 management units, namely Water Conservation Area (WCA) 1, 2, 3, and the Everglades National Park (ENP), respectively, with most Hg being stored in soil. The current annual Hg inputs account only for 1-2% of the legacy Hg. Mercury transport across management units during a season amounts to 1% or less of Hg storage, except for WCA 2 where inflow inputs can contribute 4% of total MeHg storage. Mass budget suggests distinct spatiality for cycling of seasonally deposited Hg, with significantly lower THg fluxes entering water and floc in ENP than in the WCAs. Floc in WCAs can retain a considerable fraction (around 16%) of MeHg produced from the newly deposited Hg during the wet season. This work is important for evaluating the magnitude of legacy Hg contamination and for predicting the fate of new Hg in the Everglades, and provides a methodological example for large-scale studies on Hg cycling in wetlands.

AB Zinc oxide nanoparticles (ZnO NPs) are being rapidly developed for use in consumer products, wastewater treatment, and chemotherapy providing several possible routes for ZnO NP exposure to humans and aquatic organisms. Recent studies have shown that ZnO NPs undergo rapid dissolution to Zn(2+), but the relative contribution of Zn(2+) to ZnO NP bioavailability and toxicity is not clear. We show that a fraction of the ZnO NPs in suspension dissolves, and this fraction cannot account for the toxicity of the ZnO NP suspensions to Daphnia magna. Gene expression profiling of D. magna exposed to ZnO NPs or ZnSO(4) at sublethal concentrations revealed distinct modes of toxicity. There was also little overlap in gene expression between ZnO NPs and SiO(x) NPs, suggesting specificity for the ZnO NP expression profile. ZnO NPs effected expression of genes involved in cytoskeletal transport, cellular respiration, and reproduction. A specific pattern of differential expression of three biomarker genes including a multicystatin, ferritin, and C1q containing gene were confirmed for ZnO NP exposure and provide a suite of biomarkers for identifying environmental exposure to ZnO NPs and differentiating between NP and ionic exposure.

AB There is evidence from both epidemiology and laboratory studies that perfluorinated compounds may be immunotoxic, affecting both cell-mediated and humoral immunity. The overall goal of this study was to investigate the mechanisms underlying the immunotoxic effects of perfluorooctane sulfonate (PFOS) and perfluorooctane acid (PFOA), using in vitro assays. The release of the pro-inflammatory cytokines IL-6, IL-8, and TNF-alpha was evaluated in lipolysaccharide (LPS)-stimulated human peripheral blood leukocytes and in the human promyelocytic cell line THP-1, while the release of IL-4, IL-10 and IFN-gamma was evaluated in phytohaemagglutinin (PHA)-stimulated peripheral blood leukocytes. PFOA and PFOS suppressed LPS-induced TNF-a production in primary human cultures and THP-1 cells, while IL-8 was suppressed only in THP-1 cells. IL-6 release was decreased only by PFOS. Both PFOA and PFOS decreased T-cell derived, PHA-induced IL-4 and IL-10 release, while IFN-gamma release was affected only by PFOS. In all instances. PFOS was more potent than PFOA. Mechanistic investigations carried out in THP-1 cells demonstrated that the effect on cytokine release was pre-transcriptional, as assessed by a reduction in LPS-induced TNF-a mRNA expression. Using siRNA, a role for PPAR-a could be demonstrated for PFOA-induced immunotoxicity, while an inhibitory effect on LPS-induced I-NB degradation could explain the immunomodulatory effect of PFOS. The dissimilar role of PPAR-a in PFOA and PFOS-induced immunotoxicity was consistent with the differing effects observed on LPS-induced MMP-9 release: PFOA, as the PPAR-a agonist fenofibrate, modulated the release, while PFOS had no effect. Overall, these studies suggest that PFCs directly suppress cytokine secretion by immune cells, and that PFOA and PFOS have different mechanisms of action. (C) 2010 Elsevier Inc. All rights reserved.

AB Nitrous oxide (N2O) is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. Anthropogenic nitrogen (N) loading to river networks is a potentially important source of N2O via microbial denitrification that converts N to N2O and dinitrogen (N-2). The fraction of denitrified N that escapes as N2O rather than N-2 (i.e., the N2O yield) is an important determinant of how much N2O is produced by river networks, but little is known about the N2O yield in flowing waters. Here, we present the results of whole-stream N-15-tracer additions conducted in 72 headwater streams draining multiple land-use types across the United States. We found that stream denitrification produces N2O at rates that increase with stream water nitrate (NO3-) concentrations, but that <1% of denitrified N is converted to N2O. Unlike some previous studies, we found no relationship between the N2O yield and stream water NO3-. We suggest that increased stream NO3- loading stimulates denitrification and concomitant N2O production, but does not increase the N2O yield. In our study, most streams were sources of N2O to the atmosphere and the highest emission rates were observed in streams draining urban basins. Using a global river network model, we estimate that microbial N transformations (e. g., denitrification and nitrification) convert at least 0.68 Tg.y(-1) of anthropogenic N inputs to N2O in river networks, equivalent to 10% of the global anthropogenic N2O emission rate. This estimate of stream and river N2O emissions is three times greater than estimated by the Intergovernmental Panel on Climate Change.

AB Human exposure to air pollution transported from the Midwest is evaluated in eight New York State (NYS) regions over ten summers (1997 - 2006) for association with respiratory-related hospital admissions. Days when pollution is transported into the Northeastern United States (U. S.) were identified by using back-trajectories from the eight regions. These back-trajectories help identify predominant meteorological patterns associated with "polluted" air parcels (originating in the Midwest where power plant emissions are known to be relatively high) and "clean" air parcels (originating from the North where pollution is known to be relatively low). Ambient ozone concentrations measurements were used to validate the classification of "polluted" and "clean" air parcels. These classifications were then used to define the days of high-versus low-exposure for populations residing within each region. The results of this analysis indicate that the risk of being hospitalized for respiratory-related illness in NYS is greater on those days when air is transported from the Midwest as compared to days when air is transported from the North. Using a refined method to examine air parcels moving through a boundary drawn around high-emitting power plants in the Midwestern U. S. resulted in stronger associations across more regions (significant odds ratios ranging from 1.06 to 1.16 for the entire study time period for six of the eight NYS regions). An assessment of temperature and its impact on the odds ratio calculation in the New York City metropolitan region indicates that temperature alone does not explain the increased association between air pollution and respiratory-related hospital admissions.

AB Following the Part I paper that describes an application of the U. S. EPA Models-3/Community Multiscale Air Quality (CMAQ) modeling system to the 1999 Southern Oxidants Study episode, this paper presents results from process analysis (PA) using the PA tool embedded in CMAQ and subsequent sensitivity simulations to estimate the impacts of major model uncertainties identified through PA. Aerosol processes and emissions are the most important production processes for PM2.5 and its secondary components, while horizontal and vertical transport and dry deposition contribute to their removal. Cloud processes can contribute the production of PM2.5 and SO42- and the removal of NO3 and NH4+. The model biases between observed and simulated concentrations of PM2.5 and its secondary inorganic components are found to correlate with aerosol processes and dry deposition at all sites from all networks and sometimes with emissions and cloud processes at some sites. Guided with PA results, specific uncertainties examined include the dry deposition of PM2.5 species and its precursors, the emissions of PM2.5 precursors, the cloud processes of SO42-, and the gas-phase oxidation of SO2. Adjusting the most influential processes/factors (i.e., emissions of NH3 and SO2, dry deposition velocity of HNO3, and gas-phase oxidation of SO2 by OH) is found to improve the model overall performance in terms of SO42-, NO3-, and NH4+ predictions.

ID ATMOSPHERIC BOUNDARY-LAYER; NONLOCAL CLOSURE-MODEL; SYSTEM
AB A recently published meteorology and air quality modeling study has several serious deficiencies deserving comment. The study uses the weather research and forecasting/chemistry (WRF/Chem) model to compare and evaluate boundary layer and land surface modeling options. The most serious of the study's deficiencies is reporting WRF/Chem results for both meteorological and chemical quantities using the asymmetric convective model version 2 (ACM2). While the ACM2 is a valid model option for WRF, it has not yet been implemented for the chemical portion of the WRF/Chem model. Hence, the reported air quality modeling results using ACM2 are invalid. Furthermore, publication of these results gives the erroneous impression that the ACM2 model is not well suited for air quality applications when, in fact, it is the default boundary layer model in the community multiscale air quality (CMAQ) model.

AB Xikeng Reservoir is one of the major water supply reservoirs in Shenzhen. The water quality of Xikeng Reservoir has been poor, with much of the pollution coming from nonpoint sources. An innovative low impact development type of BMP called the BioBox was used at the Administration Building parking lot location, as a research site and demonstration project to show how small alterations to parking lot designs can dramatically decrease pollutant loads. Manual samples were collected during storm events and analyzed for total suspended solids (TSS); five-day biochemical oxygen demand (BOD5); ammonia nitrogen (NH3-N), and total phosphorus (TP). In summary, the ranges of removal rates of the BioBox are: TSS 70% - 90%; BOD5 20% - 50%, and ammonia and phosphorus 30% - 70%. The BioBox system effectively reduced the concentrations of pollutants in the parking lot runoff.

The main objectives of the study were to apply a water quality model to a complex coastal lagoon system, to evaluate its effectiveness, and to prepare guidelines for future water quality modeling studies in such complex systems as well as emphasizing the difficulties faced in developing countries in regard to data availability. Koycegiz - Dalyan Lagoon was selected as the study area that is located at the southwest of Turkey along the Mediterranean Sea Coast. Water Quality Analysis Simulation Program version 7 (WASP7) eutrophication module (WASP/EUTRO) was determined to be the most appropriate model for the area of concern. The lagoon system is divided into 49 longitudinal segments, since horizontal and vertical salinity gradients exist in the system, each longitudinal segment is divided into two as upper and bottom segments; therefore, 98 segments represent the lagoon system. During the water quality modeling study, 4 sets of simulations were conducted sequentially starting from the simplest complexity level to higher complexity levels in order to better understand the processes and mechanisms that occur in the system. NH3-N, NO3--N, Organic N, Detrital N, PO43--P, Organic P, Detrital P, dissolved oxygen, CBOD, detrital carbon, salinity and phytoplankton were simulated in the study. The approaches taken here could help as a guide and example for other developing countries that aim to conduct water quality modeling studies. The study should encourage researchers to initiate similar modeling studies of other lagoons in the world, where lack of data is considered to be a major handicap.

AB The objective of these studies was to evaluate the use of an in silico model for predicting lung deposition of inhaled therapeutic aerosols. A range of input data derived from our own in vitro data and published clinical studies was utilized. The in silico model ran simulations for these propellant driven metered dose inhaler formulations across a range of conditions. Firstly, a range of pressurized metered dose inhaler formulations were evaluated in the in silico model and compared to the in vitro aerosol performance data. Limitations of using in vitro cascade impaction data were observed. Then, using in vivo data from healthy human subjects using metered dose inhalers, lung deposition profiles were compared with the in silico model predictions. Despite differences in oropharyngeal deposition the model predicted lung deposition accurately. We conclude that the in silico model can be applied to various conditions for particulate based inhalation aerosol systems.

AB In addition to its well-defined role as an antagonist in apoptosis, we propose that BCL2 may act as an intracellular suppressor of cell motility and adhesion under certain conditions. Our evidence shows that, when overexpressed in both cancer and non-cancer cells, BCL2 can form a complex with actin and gelsolin that functions to decrease gelsolin-severing activity to increase actin polymerization and, thus, suppress cell adhesive processes. The linkage between increased BCL2 and increased actin polymerization on the one hand and suppression of cell adhesion, spreading and motility on the other hand, is a novel observation that may provide a plausible explanation for why BCL2 overexpression in some tumors is correlated with improved patient survival. In addition, we have identified conditions in vitro in which F-actin polymerization can be increased while cell motility is reduced. These findings underscore the possibility that BCL2 may be involved in modulating cytoskeleton reorganization and may provide an opportunity to explore signal transduction pathways important for cell adhesion and migration and to develop small molecule therapies for suppression of cancer metastasis.

ID EMERGY ANALYSIS
AB Approaching a Net Zero Energy (NZE) building goal based on current definitions is flawed for two principal reasons - they only deal with energy quantities required for operations, and they do not establish a threshold, which ensures that buildings are optimized for reduced consumption before renewable systems are integrated to obtain an energy balance. This paper develops a method to maximize renewable resource use through emergy (spelled with an "m") analysis. A "Renewable Emergy Balance" (REB) in environmental building design is proposed as a tool to maximize renewable resource use through disinvestment of all non-renewable resources that may be substituted with renewable resources. REB buildings attain a high standing by optimizing building construction over their entire life-span from formation-extraction-manufacturing to maintenance and operation, and material reuse at the end of building life-time.

AB In the present study, natural and anthropogenic sources of particulate organic carbon (OCp) and elemental carbon (EC) have been quantified based on weekly filter samples of PM10 (particles with aerodynamic diameter < 10 mu m) collected at four Nordic rural background sites [Birkenes (Norway), Hyytiala (Finland), Vavihill (Sweden), Lille Valby, (Denmark)] during late summer (5 August-2 September 2009). Levels of source specific tracers, i.e. cellulose, levoglucosan, mannitol and the C-14/C-12 ratio of total carbon (TC), have been used as input for source apportionment of the carbonaceous aerosol, whereas Latin Hypercube Sampling (LHS) was used to statistically treat the multitude of possible combinations resulting from this approach.
The carbonaceous aerosol (here: TCp; i.e. particulate TC) was totally dominated by natural sources (69-86%), with biogenic secondary organic aerosol (BSOA) being the single most important source (48-57%). Interestingly, primary biological aerosol particles (PBAP) were the second most important source (20-32%). The anthropogenic contribution was mainly attributed to fossil fuel sources (OCff and ECff) (10-24%), whereas no more than 3-7% was explained by combustion of biomass (OCbb and ECbb) in this late summer campaign i.e. emissions from residential wood burning and/or wild/agricultural fires. Fossil fuel sources totally dominated the ambient EC loading, which accounted for 4-12% of TCp, whereas < 1.5% of EC was attributed to combustion of biomass. The carbonaceous aerosol source apportionment showed only minor variation between the four selected sites. However, Hyytiala and Birkenes showed greater resemblance to each other, as did Lille Valby and Vavihill, the two latter being somewhat more influenced by anthropogenic sources.
Ambient levels of organosulphates and nitrooxy-organosulphates in the Nordic rural background environment are reported for the first time in the present study. The most abundant organosulphate compounds were an organosulphate of isoprene and nitrooxy-organosulphates of alpha- and beta-pinene and limonene.

TI Present and Future Approaches to Urban Pest Management: a Global
Pesticide Regulatory Perspective
SO URBAN PEST MANAGEMENT: AN ENVIRONMENTAL PERSPECTIVE
LA English
DT Article; Book Chapter
ID WOLBACHIA INFECTION; MOSQUITO
AB Global demand for pesticide products characterized by low toxicity, short residual life and an increased specificity for the pest(s) is increasing. At the same time, the public desire for highly efficacious products that can eliminate pests efficiently, but without pesticides, or with the use of only 'green' products, is at its height. Future pest control solutions will not come solely from conventional pesticides and/or green pest management practices but also from advances in biotechnology and new applications for nanoparticles. This new paradigm brings challenges to regulatory systems, pesticide developers and pesticide applicators during a time when the emergence and resurgence of urban pest problems and vector-borne diseases throughout the world is intensifying. Precaution will be the underlying theme of pesticide legislative mandates and regulatory agencies, which will take a more conservative approach to pesticide risk and exposure assessments where uncertainty exists. Risks to vulnerable populations such as children and the elderly will be emphasized. Shifts towards precautionary principles will make benefit assessments essential, together with research to support the continued use of pest control products and methods. There is an immediate need to develop benefit models for the control of urban pests. Urban pest management programmes must emphasize sustainable practices that include new approaches, technologies and strategies, and integrated pest or vector management principles and practices to help reduce risks in order to satisfy possible future regulatory mandates. This chapter discusses outlooks and trends for pest management and regulatory policy, and suggests recommendations for meeting future challenges.

AB Coastal eutrophication models have proposed that various environmental conditions can serve as filters mediating the effects of nutrient loading on coastal ecosystems. Variation in such filters due to natural or anthropogenic causes can potentially lead to varied responses in overall eutrophication expression as well as in individual eutrophication indicators. In this study, we sought to identify factors that affect eutrophication expression at contrasting sites within one nutrient-loaded estuary in central California. We developed and applied a eutrophication expression index to 18 sites in the Elkhorn Slough estuary and then used principal components analysis of environmental drivers (nutrients) and filters to determine how they relate to overall eutrophication expression as well as to individual eutrophication indicators. We also examined the relationship between one key filter, tidal range, and eutrophication indicators. Elkhorn Slough was determined to be a moderately eutrophic estuary, with individual sites varying from being low to hypereutrophic. Eutrophication expression was explained mostly by tidal range, depth, temperature, salinity, distance to estuary mouth, and turbidity, but not by nutrient concentrations. Tidal range in particular correlated strongly with most eutrophication indicators. Sites with artificially dampened tidal range through water control structures were more eutrophic than sites with full tidal exchange. Results from this study emphasize the importance of filters in mediating the negative ecological effects of eutrophication. Coastal managers can decrease eutrophication expression at a local scale by managing for filters (e. g. increasing tidal exchange to managed wetlands), complementing efforts to reduce eutrophication at a regional scale by decreasing nutrient loading.

AB Despite the wide ranging applications of time series methodologies for stochastic processes, they have not been used for environmental economics (except climate change). To fill this gap, we introduce time series methodology for the environmental econometrics, presenting autoregressive, moving average, ARCH, GARCH, and ARMAX models. These models are applied to establish a functional relationship between pathogen indicator and meteorological and environmental variables using time series data associated with Huntington Beach, Ohio. According to ARCH, turbidity, dew point, flow, and rainfall are statistically significant variables. Other models produced roughly similar results because of the short lag order Models confirm the lag order of one using Akaike, Schwartz, and Hannan-Quinn selection criteria, reflecting very short memory of the pathogen indicator series. However, the time series did not support GARCH variance structure. These models not only under forecasted observations at both ends of the distribution of the data, but also simultaneously underforecasted advisories.

AB With the concentrations of atmospheric greenhouse gases (GHGs) rising to levels unprecedented in the current glacial epoch, the earth's climate system appears to be rapidly shifting into a warmer regime. Many in the international science and policy communities fear that the fundamental changes in human behavior, and in the global economy, that will be required to meaningfully reduce GHG emissions in the very near term are unattainable. In the 1970s, discussion of "geoengineering," a radical strategy for arresting climate change by intentional, direct manipulation of the Earth's energy balance began to appear in the climate science literature. With growing international concern about the pace of climate change, the scientific and public discourse on the feasibility of geoengineering has recently grown more sophisticated and more energetic. A wide array of potential geoengineering projects have been proposed, ranging from orbiting space mirrors to reduce solar flux to the construction of large networks of processors that directly remove carbon dioxide from the atmosphere. Simple estimates of costs exist, and some discussion of both the potentially negative and "co-beneficial" consequences of these projects can be found in the scientific literature.
The critical, missing piece in the discussion of geoengineering as a strategy for managing climate is an integrated evaluation of the downstream costs-versus-benefits inter-comparing all available climate management options, including geoengineering. Our examination of the literature revealed a number of substantial gaps in the knowledge base required for such an evaluation. Therefore, to ensure that the decision framework arising from this analysis is well founded, a focused program of scientific research to fill those gaps is also essential. As with any sound engineering plan, international decisions on how to address human-induced climate warming must be founded on a thoughtful and well-informed analysis of all of the available options.

DT Article; Book Chapter
ID REFORM
AB China, India, and Mexico are among the top developing country emitters of CO2. The electric power sectors in China and India is dominated by coal-fired power plants, whereas fuel oil and natural gas are the key fossil fuels in Mexico. Spurred by economic development and population growth, demand for electricity in these countries is expected to continue to rise. Meeting this increased demand will have a significant impact on emissions of greenhouse gases (GHG). While available portfolio of generation and mitigation technologies may not suffice to arrest the growth of emissions, it can help reduce the rate of emissions growth. To achieve significant reductions, multiple approaches are required, such as reducing demand by adopting end-use efficiency improvement measures, accelerating the deployment of renewable and nuclear power, and adopting cleaner more efficient generation technologies. Retrofitting the existing fleet to meet strengthened environmental standards, and accelerated fleet-turnover, coupled with adoption of state-of-the-art high efficiency generation technologies, such as supercritical and ultra-supercritical boilers and advanced combined-cycle gas turbines, should play an important role in meeting the increasing demand with the least amount of GHG emissions. In parallel, significant R&D efforts will have to be undertaken to adapt off-the-shelf generation technologies to suit local needs. In the medium to long term, developed countries will need to provide financial and technical support for these countries and partner with them to develop, design, demonstrate, and deploy technologies for capturing and sequestering carbon dioxide.

AB The Fourth Assessment Report released by the Intergovernmental Panel on Climate Change (IPCC) in 2007 was unequivocal in its message that warming of the global climate system is now occurring, and found, with "very high confidence" that it was "very likely" that the observed warming was due to anthropogenic emissions of greenhouse gases (GHGs). To address the problem, the IPCC developed an outline of approaches to reduce GHG emissions to desired levels. The expected changes in technologies and practices needed to mitigate emissions of GHGs will lead to changes in the impacts to the environment associated with energy production and use. Some of these changes will be beneficial, but others will not. This chapter identifies some of the potential environmental impacts (other than the intended mitigation of climate change) of implementing GHG mitigation strategies, but will not attempt to quantify those impacts or their costs. Included are discussions of the impacts of implementing energy efficiency and conservation measures, fuel switching in the power generation sector, nuclear and renewable energy, carbon capture and storage, use of biofuels and natural gas for transportation fuels, and hydrogen and electricity for transportation energy. Environmental impacts addressed include changes in air emissions of nitrogen oxides, sulfur dioxide, and particulate matter; impacts to water quality and quantity; increased mining of coal to meet the power demands of carbon capture systems and of metals to meet demands for vehicle batteries; and impacts to ecosystems associated with biofuel production and siting of other renewable energy systems.

AB The European green crab Carcinus maenas is one of the world's most widely recognized marine invaders. The success of this species has provided opportunities to explore genetic patterns associated with establishment and population expansion following independent introduction events to widely different recipient ecosystems. Recent studies have revealed an extraordinary diversity of such patterns. Globally, genetic reconstruction of invasion histories suggests complicated scenarios comprising multiple introductions to some regions as well as secondary introductions deriving from previously established invasive populations. In addition, detailed genetic analyses of several introduced populations indicate that successful invasion may involve rapid expansion from single low diversity founder populations, multiple introductions from genetically distinct sources with subsequent intraspecific admixture, or even interspecific hybridization between C. maenas and its sibling species C. aestuarii. The complexity of this global picture highlights the contingent nature of individual biological invasion events. Nevertheless, genetic study of non-native Carcinus populations provides crucial insights into invasion dynamics relevant to green crab management and control, and offers an unusually rich system within which to explore the genetic consequences of colonizations and range expansions in coastal marine ecosystems.

AB Businger and Delany (1990) presented an approach to estimate the sensor resolution required to limit the contribution of the uncertainty in the chemical concentration measurement to uncertainty in the flux measurement to 10% for eddy covariance, gradient, and relaxed eddy accumulation flux measurement methods. We describe an improvement to their approach to estimate required sensor resolution for the covariance method, and include disjunct eddy covariance. In addition, we provide data to support selection of a form for the dimensionless scalar standard deviation similarity function based on observations of the variance of water vapor fluctuations from recent field experiments. We also redefine the atmospheric parameter of Businger and Delany in a more convenient, dimensionless form. We introduce a "chemical parameter" based on transfer velocity parameterizations. Finally, we provide examples in which the approach is applied to measurement of carbon dioxide, dimethylsulfide, and hexachlorobenzene fluxes over water. The information provided here will be useful to plan field measurements of atmosphere-surface exchange fluxes of trace gases.

AB In this chapter, we review human health effects associated with the brominated flame retardants (BFRs) that have constituted the overwhelming majority of BFR production and subsequent exposure in humans. These include tetrabromobisphenol A (TBBPA), hexabromocyclododecane (HBCD), and three commercial mixtures of polybrominated diphenyl ethers (PBDEs), or biphenyl oxides, which are known as decabromodiphenyl ether (DecaBDE), octabromodiphenyl ether (OctaBDE), and pentabromodiphenyl ether (PentaBDE). The primary endpoint of concern appears to be endocrine disruption. Other potential effects include hepatotoxicity and neurotoxicity, the later particularly during development. While the toxicological database for these chemicals is growing, further research is needed to understand potential health effects associated with less-studied PBDE congeners, examine the potential carcinogenicity of HBCD and TBBPA, and investigate the overall toxicity of a number of developing alternative BFRs. The increasing contamination of the environment and people by BFRs coupled with clear evidence of adverse health effects resulting from their exposure highlights the importance of identifying emerging issues and data gaps to fully understand the human health risks.

AB Ecological Risk Assessment related to soil contamination requires a conceptual framework and practical tools to support Risk Management. The conceptual framework is provided by the Risk Assessment paradigm, which means that risks are assessed based on an Exposure Assessment and an Effect Assessment step. Current practical tools to appraise soil quality by Ecological Risk Assessment are: (1) comparison of soil contaminant concentrations to ecological Soil Quality Standards; (2) quantification of ecological risks by modeling; (3) quantification of impacts in bioassays or in field monitoring; and (4) quantification of ecological risks by weight-of-evidence approaches. The present chapter concerns the theory and practices of Effect Assessment and risk modeling using Species Sensitivity Distributions (SSDs), and similar Functional Sensitivity Distributions (FSDs). SSD- and FSD-based Risk Assessment outputs are used for the appraisal of soil quality, soil protection and the management of (slightly and highly) contaminated sites, for both the upper soil and the groundwater. For the appraisal of soil and soil protection, one can derive Hazardous Concentrations (HCs) for individual contaminants, which are estimates of the concentration of a chemical that would affect a defined fraction of species. Likewise, one can derive Hazard Potentials (HPs) for contaminated soil samples, which represent effects levels for a certain fraction of the tested soil species when exposed in such a soil. This chapter introduces the theory of SSDs and illustrates the types of practical applications of SSD-based effect and risk models in all four of the aforementioned types of tools. Since Risk Assessment requires assessments of exposure as well as effects, the chapter also discusses Exposure Assessments for SSDs. Practical software models and database tools are described, to support easy application of SSDs in practice. Through the examples, the reader is informed on a multitude of useful options for SSD-based assessment. SSD-modeling is versatile, and can be of use to a range of soil contamination problems, from diffuse contamination in large areas to local contamination hot spots.

AB Whole sediment toxicity identification evaluation (TIE) methods were developed primarily in the late 1990s and early 2000s in research programs dedicated to developing manipulations and endpoints to characterize and identify causes of toxicity to benthic freshwater and marine organisms. The focus of these methods included nonionic organic contaminants, cationic and anionic metals, and ammonia. This chapter discusses innovations in whole sediment TIE manipulations and endpoints developed primarily over the last 10 years. Innovations such as the use of supercritical fluid extraction as a Phase III manipulation, Phase II methods for identifying pyrethroid, organophosphate, and carbamate pesticides, and the integration of genomic endpoints into the TIE structure are described. In North America, recently implemented environmental regulations require the diagnosis and identification of environmental stressors as part of the total maximum daily loading process. These regulations are likely to result in an increase in the conduct of whole sediments TIEs and encourage the development and application of more innovations.

AB Molecular techniques based on genomics, proteomics and transcriptomics are rapidly growing as complete microbial genome sequences are becoming available, and advances are made in sequencing technology, analytical biochemistry, microfluidics and data analysis. While the clinical and food industries are increasingly adapting these techniques, there appear to be major challenges in detecting health-related microbes in source and treated drinking waters. This is due in part to the low density of pathogens in water, necessitating the processing of significantly large volume samples. In this chapter, the state-of-the-art techniques available for pathogen detection and characterization from water are discussed. From the vast panorama of available techniques, only those that are finding a place in the water industry are presented. Quantitative PCR is the prime focus of this chapter, along with protein detection and immunological approaches, with other molecular techniques such as loop-mediated isothermal amplification (LAMP) and microarrays being the focus of other chapters. A detailed section on future trends is also included.

AB Methods for the detection of microorganisms in drinking or source water invariably involve the collection of a water sample and some treatment to reduce the volume of that sample. Numerous methods have been developed for water sample collection and subsequent treatment of this collected sample, including filtration, sedimentation, and attraction of the microorganisms of interest to various molecules or substrates. Once the sample volume has been reduced, it is imperative to remove some of the non-target elements of the sample, as these substances generally interfere with the detection of microorganisms. Application of many molecular technologies for sample treatment involves a further step of extraction of genetic material from the microorganisms. Although mechanisms and techniques have been devised for each part of the sample collection and treatment process, there is considerable room for improvement.

An overview of the principals of the technology, workflow, sequencing strategies, and data analysis challenges are included. In addition, the bacterial population structure of an untreated wastewater sewage sample is reported and discussed to demonstrate a pyrosequencing approach for studying a microbial community. Emphasis is placed on the application of pyrosequencing technology for recreational water quality management including the discovery of alternative indicators of faecal pollution and improving the link between faecal pollution and the transmission of waterborne disease.

AB Regulations in the United States and elsewhere stipulate that drinking and recreational waters should be regularly monitored for microbial indicators of faecal pollution. Hence, the health risks associated with these waters are determined using microbial surrogates rather than by direct pathogen detection. Detecting pathogens may seem more appropriate, however, pathogens are difficult to enumerate since they are often present in environmental samples in very low numbers that still present health concerns and may take several days to weeks to detect, lessening their value for risk management. In this chapter, we discuss the use of molecular methods that attempt to track faecal sources of pollution in environmental waters and discuss their role in environmental monitoring and management. A general description of the most commonly used methods is provided, and where appropriate, some of the advantages and limitations are highlighted. The use of genomic technologies to develop new methods and to fill existing research gaps in microbial source tracking (MST) is also discussed. As clear from other chapters of this book, the field of environmental microbiology is undergoing a fundamental change through the development of tools that can describe the molecular diversity of microbial populations relevant to environmental faecal pollution. While this is a dynamic field, emphasis is placed on culture-independent methods relying on DNA-based targets that currently dominate the scientific literature.

AB Climate change studies are often interdisciplinary by nature, incorporating many domains of science, economics, and political theory. Integrated assessment (IA) aims to bring diverse scientific, economics and social science expertise together to provide analysis and advice that comprehensively addresses all or at least many aspects of the climate change issue. IA methods have been applied to many areas of climate change providing insights into areas such as optimal timing of emission reductions, weighting of different greenhouse gases, or impacts of biofuel policies. Additionally, IAs have identified key uncertainties that should be priorities of future research, such as the need to understand oceanic heat uptake in order to better constrain climate sensitivity and predict future timing of temperature change. These assessments have also served to establish ongoing communication within the community of researchers, and between researchers and policy makers. In complex scientific issues it is often difficult for policy makers and the public to sort out conflicting scientific views, and an authoritative assessment process can provide consensus views on the issue, accepting that in some cases the "consensus"' may be that some aspects of the issue remain unresolved. This review explores the history and applications of these IAs, and identifies avenues for future emphasis. We briefly review the whole field of IAs of climate change, but focus on the role of formal computational frameworks in IA models. (c) 2010 John Wiley & Sons, Ltd.

ID SEA-LEVEL RISE; UNITED-STATES; HOLDING BACK; COST
AB Sea-level rise (SLR) increases the risk of permanent inundation of coastal lands and structures, while also increasing the risk of periodic damage from storms and risks to ecological resources. Prior studies have illustrated the importance of considering adaptation measures, such as armoring and beach nourishment, when estimating the economic cost of SLR, but these studies have taken the form either of careful, geographically limited case studies or national estimates based on limited samples. We present a framework for evaluating the economics of adaptation to permanent inundation from SLR that employs detailed local scale data and is spatially comprehensive, and apply the framework to estimate costs of adaptation for the full coastline of the continental US. Our results show that the economic cost of SLR is much larger than prior estimates suggest-more than $63 billion cumulative discounted cost (at 3%) for a 68 cm SLR by 2100, and $230 billion undiscounted-yet is only one-fourth the total value of low-lying property vulnerable to SLR, illustrating the importance of careful site-specific consideration of adaptation. Further, the granularity of the framework provides spatial, temporal, and response mode details useful to both national policy-makers and local adaptation planners, and can readily incorporate estimates of ecological and storm surge damages as they become available.

AB We used stream chemistry and hydrogeomorphology data from 549 stream and 447 river sites to estimate NO(3)-N removal in the Upper Mississippi, Missouri, and Ohio Rivers. We used two N removal models to predict NO(3)-N input and removal. NO(3)-N input ranged from 0.01 to 338 kg km(-1) d(-1) in the Upper Mississippi River to < 0.01-54 kg km(-1) d(-1) in the Missouri River. Cumulative river network NO(3)-N input was 98700-101676 Mg year(-1) in the Ohio River, 85961-89288 Mg year(-1) in the Upper Mississippi River, and 59463-61541 Mg year(-1) in the Missouri River. NO(3)-N output was highest in the Upper Mississippi River (0.01-329 kg km(-1) d(-1)), followed by the Ohio and Missouri Rivers (< 0.01-236 kg km(-1) d(-1)) sub-basins. Cumulative river network NO(3)-N output was 97499 Mg year(-1) for the Ohio River, 84361 Mg year(-1) for the Upper Mississippi River, and 59200 Mg year(-1) for the Missouri River. Proportional NO(3)-N removal (PNR) based on the two models ranged from < 0.01 to 0.28. NO(3)-N removal was inversely correlated with stream order, and ranged from < 0.01 to 8.57 kg km(-1) d(-1) in the Upper Mississippi River to < 0.001-1.43 kg km(-1) d(-1) in the Missouri River. Cumulative river network NO(3)-N removal predicted by the two models was: Upper Mississippi River 4152 and 4152 Mg year(-1), Ohio River 3743 and 378 Mg year(-1), and Missouri River 2277 and 197 Mg year(-1). PNR removal was negatively correlated with both stream order (r = -0.80-0.87) and the percent of the catchment in agriculture (r = -0.38-0.76).

AB In the wake of the 2001 terrorist attacks, the use of Bacillus anthracis (anthrax) in bioterrorism attacks has emerged as a realistic concern. Thus, a contingency plan is needed to inform decision-makers about which response actions are appropriate and justified under which circumstances. This study considers the decisions: (1) to undertake prophylactic antibiotic treatment; (2) to vaccinate individuals; or (3) to decontaminate the building. While these response actions are clearly justified for highly exposed individuals, a very large number of individuals exposed to very small risks in areas outside of the immediate vicinity of the release are also likely. Our results indicate that there are non-negligible risk thresholds below which response actions produce more costs than benefits. For the base case, the thresholds range from a risk of 1 in 33 for decontamination by fumigation to 1 in 6,547 for antibiotic prophylaxis and 1 in 7,108 for vaccination. A one-way sensitivity analysis on uncertain variables indicates less than an order of magnitude change in these thresholds. Benefit-cost analysis is a useful tool for assessing tradeoffs among alternative decisions, but cannot be the sole criterion in responding to incidents because of inherent limitations.

AB Land-based sources of pollution are a major threat to the health of coral reefs. We report, for the first time, a study that relates coral reef condition to human modifications of the landscape. Stony coral community richness, cover, colony size, and density were assessed along with 3-dimensional coral cover in the near-shore waters of St. Croix, US Virgin Islands, in 2006 and 2007. Land use/land cover data (LULC, 2.4 m resolution) and a landscape development intensity (LDI) index, an indicator of human activity calculated from the LULC data, were used to explore relationships with coral indicators. The LDI index was more robust than other indicators of human activity, exhibiting negative correlations with stony coral colony density, taxa richness, colony size, and total coral cover. High variability observed in coral density and taxa richness was better explained when percent natural land and average coral station depth were considered along with the LDI index. Percent impervious surface in the watershed was negatively correlated with 1 coral condition indicator, total coral cover. The LDI index is an effective landscape indicator of human impact on St. Croix corals, highlighting the link between land-based human activity and marine ecosystems. Further development of this tool will aid in land use planning and prioritization of conservation efforts.

AB One of the most visible consequences of eutrophication in freshwater lakes is an increase in the biomass of cyanobacteria. While growth of cyanobacteria has been shown to be coupled to water column concentrations of total phosphorus (TP) in natural lakes, the ecological behavior of cyanobacteria in turbid impoundments is less well understood. Patterns of cyanobacterial biovolume in 7 turbid Kansas (USA) reservoirs exhibited overlap with published data from natural lakes in North America. Non-algal turbidity (NAT) influenced the relationship between cyanobacteria and TP in these systems. Relative to yields predicted from natural lakes, the biomass of cyanobacteria per unit TP was typically higher in the reservoirs, except in those systems that had exceptionally high levels of NAT (2.0 2/m) where observed concentrations were mostly lower than predicted. A more consistent pattern was observed with respect to the effects of NAT on yields of chlorophyll-a per unit TP in the reservoirs: across almost the entire NAT gradient, observed chlorophyll-a concentrations were typically lower than those predicted from natural lakes. Taken together, our results confirm that NAT plays an important role in regulating relationships between TP and phytoplankton biomass in reservoir ecosystems.

AB The hemlock woolly adelgid is an invasive insect that is damaging hemlock forests in the eastern United States. Several control methods are available but forest managers are constrained by cost, availability, and environmental concerns. As a result forest managers must decide how to allocate limited conservation resources over heterogeneous landscapes. We develop an attribute-based contingent valuation approach that allows us to perform cost-benefit analysis on control programs and inform the distribution of mitigation effort over land units that provide different types of environmental services. We use this approach to examine conservation efforts on three land management units in the southern Appalachian Mountains: Great Smoky Mountains National Park and Pisgah and Nantahala National Forests. Managers of these forests are focusing their efforts on specific conservation areas chosen for their importance to human-use or ecological services. The result is a network of sites that implicitly defines a tradeoff between ecological and human-use services. Our survey is designed to examine the public's perception of this tradeoff and estimate WTP for hemlock conservation programs. The estimated benefits of conserving hemlocks in the study area outweigh the cost of the mitigation programs by two orders of magnitude. We find that there is substantial support for protection of hemlock stands providing ecological services with very little human-use value. Further, we show that benefits from the current mitigation strategy could be increased by shifting effort to protect more ecological services at the expense of sites that generate primarily human-use value.

AB Regional and global chemical transport models underpredict NOx (NO + NO2) in the upper troposphere where it is a precursor to the greenhouse gas ozone. The NOx bias has been shown in model evaluations using aircraft data (Singh et al., 2007) and total column NO2 (molecules cm(-2)) from satellite observations (Napelenok et al., 2008). The causes of NOx underpredictions have yet to be fully understood due to the interconnected nature of simulated emission, transport, and chemistry processes. Recent observation-based studies, in the upper troposphere, identify chemical rate coefficients as a potential source of error (Olson et al., 2006; Ren et al., 2008). Since typical chemistry evaluation techniques are not available for upper tropospheric conditions, this study develops an evaluation platform from in situ observations, stochastic convection, and deterministic chemistry. We derive a stochastic convection model and optimize it using two simulated datasets of time since convection, one based on meteorology, and the other on chemistry. The chemistry surrogate for time since convection is calculated using seven different chemical mechanisms, all of which predict shorter time since convection than our meteorological analysis. We evaluate chemical simulations by inter-comparison and by pairing results with observations based on NOx:HNO3, a photochemical aging indicator. Inter-comparison reveals individual chemical mechanism biases and recommended updates. Evaluation against observations shows that all chemical mechanisms overpredict NOx removal relative to long-lived methanol and carbon monoxide. All chemical mechanisms underpredict observed NOx by at least 30%, and further evaluation is necessary to refine simulation sensitivities to initial conditions and chemical rate uncertainties.

AB Carbonaceous particles smaller than 2.5 mu m aerodynamic diameter (PM(2.5)) were collected in July, 2003 over a Loblolly Pine plantation at Duke Forest, NC during the Chemical Emission, Loss, Transformation and Interactions within Canopies (CELTIC) field study. Organic (OC) and elemental (EC) carbon in PM(2.5) ranged from 1.4-6.3 and 0.08-0.41 mu g C m(-3), respectively, and concentrations measured above and below the pine canopy were in good agreement. Ambient OC was lower (<3 mu g C m(-3)) during cooler periods (daytime maximum temperatures < 28 degrees C) and for periods following precipitation events, and was higher (>3 mu g C m(-3)) during warm humid periods. Radiocarbon analysis indicates that on average 83% (range 78-91%) of the PM(2.5) carbon was derived from contemporary (biogenic VOC and biomass burning) sources. This is higher than previous estimates from urban and suburban sites, and in good agreement with recently published data from other rural sites throughout the U.S. The estimates of contemporary PM(2.5) carbon may represent a lower limit for this site since the sampler was located above the center of a 30 meter diameter plot fumigated with 200 ppm CO(2) derived from fossil carbon sources. However, this effect is likely to be negligible. The regression relationship between OC/EC ratios and percent biogenic carbon in aerosol is very similar to those observed in recent summertime data from Tennessee and Florida. However, our values for both OC/EC and percent biogenic carbon are higher than those observed in the latter studies, likely due to the more rural character of the site. Simple box model estimates indicate that biogenic VOC (BVOC) emissions measured at the site provide sufficient reactive carbon sources to account for the observed levels of aerosol biogenic carbon. The magnitude and temporal pattern in the box model secondary organic aerosol estimates correlate well with the ambient aerosol carbon measurements. The model estimates of the relative contribution of isoprene, alpha-pinene, and beta-caryophyllene oxidation to PM(2.5) carbon are in reasonable agreement with a study recently conducted at a nearby site where aerosol tracers of these compounds were quantitatively analyzed in ambient PM(2.5). Pinic acid concentrations in the below-canopy PM(2.5) during CELTIC (from another recently published study) similarly suggest a significant contribution of alpha-pinene oxidation to PM(2.5) carbon. The biomass burning tracers potassium and levoglucosan yielded fire contribution estimates to PM(2.5) consistent with their respective published emission factors. These estimates indicate that biomass burning accounted for 1 to 5% (0.015 to 0.30 mu g C m(-3)) of the PM(2.5) carbon during CELTIC. (C) 2010 Elsevier Ltd. All rights reserved.

AB The primary goal of this review and synthesis effort is to summarize present landscape patterns of key soil constituents such as carbon (C), phosphorus (P), sulfur (S), and mercury (Hg), all of which are of historical and present interest with respect to Everglades restoration. A secondary goal is to highlight the importance of landscape scale monitoring and assessment of soils in the Everglades Protection Area (EPA) with respect to present and future restoration efforts. Review of present information derived from the two independent landscape scale studies revealed significant patterns of soil thickness, organic matter, and P in the EPA. Two soil constituents of concern, Hg (biological toxicity) and S (linked to increased P cycling), also exhibit spatial patterns at the landscape scale, suggesting a need for focused efforts of restoration. Significant patterns of soil enrichment and change suggest a dynamic interaction between environmental stressors and soil biogeochemical properties across the landscape. Trends and patterns at the landscape scale in the EPA suggest that landscape scale monitoring and assessment is necessary and critical to determining the success of restoration efforts. However, several key questions, surrounding appropriate temporal and spatial sampling scales, the standardization of sampling methods, and the significance of short range variability must be addressed to facilitate future landscape scale assessment efforts.

AB Sulfur is broadly recognized as a water quality issue of significance for the freshwater Florida Everglades. Roughly 60% of the remnant Everglades has surface water sulfate concentrations above 1 mg l-1, a restoration performance measure based on present sulfate levels in unenriched areas. Highly enriched marshes in the northern Everglades have average sulfate levels of 60 mg l-1. Sulfate loading to the Everglades is principally a result of land and water management in South Florida. The highest concentrations of sulfate (average 60-70 mg l-1) in the ecosystem are in canal water in the Everglades Agricultural Area (EAA). Potential sulfur sourcesin the watershed are many, but geochemical data and a preliminary sulfur mass balance for the EAA are consistent with sulfur presently used in agricultural, and sulfur released by oxidation of organic EAA soils (including legacy agricultural applications and natural sulfur) as the primary sources of sulfate enrichment in the EAA canals. Sulfate loading to the Everglades increases microbial sulfate reduction in soils, leading to more reducing conditions, greater cycling of nutrients in soils, production of toxic sulfide, and enhanced methylmercury (MeHg) production and bioaccumulation. Wetlands are zones of naturally high MeHg production, but the combination of high atmospheric mercury deposition rates in South Florida and elevated sulfate loading leads to increased MeHg production and MeHg risk to Everglades wildlife and human consumers. Sulfate from the EAA drainage canals penetrates deep into the Everglades Water Conservation Areas, and may extend into Everglades National Park. Present plans to restore sheet flow and to deliver more water to the Everglades may increase overall sulfur loads to the ecosystem, and move sulfate-enriched water further south. However, water management practices that minimize soil drying and rewetting cycles can mitigate sulfate release during soil oxidation. A comprehensive Everglades restoration strategy should include reduction of sulfur loads as a goal because of the many detrimental impacts of sulfate on the ecosystem. Monitoring data show that the ecosystem response to changes in sulfate levels is rapid, and strategies for reducing sulfate loading may be effective in the near term. A multifaceted approach employing best management practices for sulfur in agriculture, agricultural practices that minimize soil oxidation, and changes to stormwater treatment areas that increase sulfate retention could help achieve reduced sulfate loads to the Everglades, with resulting benefits.

AB A 6-year survey (1993-1998) is summarized for fish collected from chemically contaminated, urbanized bayous in northwest Florida. Fifty-two monthly collections (January November) using trawls and seines occurred at 22 sites located in three adjacent bayous associated with the Pensacola Bay Estuary. Hurricanes Erin (Category 2) and Opal (Category 3) made landfall near the study area, and a state-wide entanglement net ban was initiated during the survey period. Approximately 585,000 fish were collected, which represented 80 species and 66 genera. The assemblages were dominated by estuarine-dependent and resident species similar to those commonly found in several nearby estuaries. Of these, Leiostomus xanthurus, Brevoortia patronus, Anchoa mitchilli, Lagodon rhomboides, and Menidia peninsulae composed 95% or more of the total catch. The total number of species for each collection ranged from 8 to 23, total abundances varied from 140 to 14,315 individuals, and Shannon diversity index values (H') were between 0.02 and 0.97. Mean species numbers and diversity index values were more consistent monthly than fish total abundance, which was influenced by seasonal occurrences of estuarine-dependent species. Hurricane effects were specific to the hurricane, structural parameter, species, and bayou. The posthurricane reductions in salinity (17% to 69%) and the few changes in fish abundance were usually temporary and within monthly and interannual variability. The resiliency of the fish assemblages to natural and anthropogenic stresses represents a survival advantage and readiness for future climatic change.

AB Environmental fluid dynamic code (EFDC), a numerical estuarine and coastal ocean circulation hydrodynamic model, was used to simulate the distribution of the salinity, temperature, nutrients, and dissolved oxygen (DO) in Perdido Bay and adjacent Gulf of Mexico. External forcing factors included the coupled effects of the astronomical tides, river discharge, and atmospheric winds on the spatial and temporal distributions of salinity and DO. Modeled time series were in good agreement with field observations of water level, nutrients, temperature, salinity, and DO. Perdido Bay and adjacent northern Gulf of Mexico coasts can be divided into two areas according to salinity, water level, and DO concentrations. The first area was lower Perdido Bay and the associated Gulf of Mexico coasts, acting primarily under the influence of tidal forcing, which increases the vertical stratification. The second division was upper Perdido Bay, which was influenced by both tidal forcing and freshwater inflow. Simulations also indicated winds influenced the salinity and DO distributions, with an enhanced surface pressure gradient. Tidal effects were also important for conducting salinity and water quality simulations in Perdido Bay. Low amplitude tides induced relatively weak vertical mixing and favored the establishment of stratification at the bay, especially along deeper bathymetry. Flood tides influenced the distribution of salinity and DO more than ebb tides, specifically along shallow bathymetry.

AB This study estimates the excess mortality attributable to excessive heat events (EHEs) for forty major U.S. cities during 1975-1995 and 1975-2004. We calculate these results using the spatial synoptic classification method to identify EHE days. Step-wise regressions are then used to estimate the location-specific mortality algorithms that can account for the impact of the EHEs' duration, severity, and timing. Our excess mortality results are expressed both as lives lost and associated mortality rates (excess deaths per 100,000 residents) using 2000 Census population estimates. Our results generally show a reduction in EHE-attributable mortality rates since 1996. Adjusting our results to account for changes in the average number of EHE days per year in each period does not affect this general conclusion. However, this adjustment has a considerable impact on a measure of the cities' relative performance in terms of reducing this EHE-attributable excess mortality. Our results indicate there is promise for further reductions in EHE-attributable mortality from the approximately 1300 excess deaths per summer we identify using data from the 1975-2004 period. However, the magnitude of this result highlights the significant health burden of EHEs relative to other extreme weather events in the United States and suggests it is worthy of additional attention. Our results also raise important questions with respect to evaluating the performance of EHE notification and response programs and how EHE-attributable mortality should be estimated for future scenarios, notably for climate change projections.

AB One of the main challenges that face successful biofiltration is the erratic loading pattern and long starvation periods. However, such patterns are common in practical applications. In order to provide long-term stable operation of a biofilter under these conditions, a cyclic adsorption/desorption beds system with flow switching was installed prior to a biofilter. Different square waves of a mixture containing n-hexane and benzene at a 2:1 ratio were applied to the cyclic adsorption/desorption beds and then fed to a biofilter. The performance of this integrated system was compared to a biofilter unit receiving the same feed of both VOCs. The cyclic adsorption/desorption beds unit successfully achieved its goal of stabilizing erratic loading even with very sharp peaks at the influent concentration equalizing influent concentrations ranging from 10-470 ppmv for n-hexane to 30-1410 ppmv for benzene. The study included different peak concentrations with durations ranging from 6 to 20 min. The cyclic beds buffered the fluctuating influent load and the followed biofilter had all the time a continuous stable flow. Another advantage achieved by the cyclic adsorption/desorption beds was the uninterrupted feed to the biofilter even during the starvation where there was no influent in the feed. The results of the integrated system with regard to removal efficiency and kinetics are comparable to published results with continuous feed studies at the same loading rates. The removal efficiency for benzene had a minimum of 85% while for n-hexane ranged from 50% to 77% according to the loading rate. The control unit showed very erratic performance highlighting the benefit of the utilization of the cyclic adsorption/desorption beds. The biofilter was more adaptable to concentration changes in benzene than n-hexane. (C) 2010 Elsevier Ltd. All rights reserved.

AB There is widespread speculation that sewage treatment plants (STPs) and aquatic environments in general may be breeding grounds for antibiotic resistant bacteria. We examine the question of whether low concentrations of antibiotics in STPs can provide or contribute to a selective pressure facilitating the acquisition or proliferation of antibiotic resistance among bacteria in the receiving environment. Examination of available literature suggests that relative levels of antibiotic resistance may be increased during sewage treatment processes. However, it is unclear whether this may be partially the result of horizontal gene transfer or entirely due to clonal propagation. While there is circumstantial evidence that the presence of antibiotics or other related genetic promoters in STP wastewaters may contribute to selective pressures for these processes, a definite role is yet to be demonstrated. Future researchers would benefit from the application of non-culture-based techniques because culture limits the possible observations to a small subset of STP microbial diversity.

AB The concentration of lead in indoor dust is a key parameter in the Integrated Exposure Uptake Biokinetic (IEUBK) model used by the U.S. Environmental Protection Agency (USEPA) to evaluate risks to children from lead in soil. The default assumption is that the concentration of lead in indoor dust is 70% of the concentration of lead in outdoor soil. This report reviews the basis of this assumption, and compares the assumption to data obtained at mining/smelting Superfund sites in USEPA Region 8. Data for lead concentrations measured in both indoor dust and outdoor soil at a number of different properties at nine different Superfund sites were fit to a linear model (Cdust = K0 + Ksd center dot Csoil). Based on ordinary linear regression, values of Ksd ranged from 0.04 to 0.34. Values of Ksd estimated using a simple method to account for measurement errors yielded values from 0.04 to 0.35. These findings indicate that the concentration of lead in dust at mining/smelting sites in Region 8 is usually not as large as the IEUBK default assumption indicates. Use of the default is likely to be protective, but will likely result in an overestimation of childhood exposure and risk from lead in soil.

TI Optimizing operational reliability of the Cincinnati contamination
warning system
SO JOURNAL AMERICAN WATER WORKS ASSOCIATION
LA English
DT Article
AB The US Environmental Protection Agency developed a contamination warning system (CWS) design with multiple, independent data streams to quickly detect unintentional or intentional contamination of drinking water distribution systems. During evaluation of the first full-scale pilot CWS in Cincinnati, Ohio, one primary design objective-optimizing operational reliability-was measured through two performance metrics: availability and data completeness. This evaluation was conducted to identify potential fail points, implement procedures to reduce downtime, and minimize lost or inaccurate data. Through two years of data collection and system optimization, the Cincinnati pilot CWS demonstrated continuous detection capabilities, even when some components or sub-components were nonfunctional. Subsequent distribution system modeling showed that the probability of experiencing a contamination incident while multiple components were nonfunctional was negligible. Overall, the optimized Cincinnati pilot CWS demonstrated robust operational reliability, with a high percentage of availability and data completeness.

life cycle assessment

ID EXPOSURE
AB Screening-level life cycle assessment (LCA) can provide a quick tool to identify the life cycle hot spots and focus research efforts to help to minimize the burdens of a technology while maximizing its benefits. The use of nanoscale silver in consumer products has exploded in popularity. Although its use is considered beneficial because of antimicrobial effects, some attention must be given to the potential environmental impacts it could impart on the life cycle of these nanoproducts as production demands escalate. This work examines the environmental impact of including silver nanoparticles in commercially available socks using screening-level LCA. Initial results suggest washing during the use phase contributes substantially more than the manufacturing phase to the product life cycle impacts. Comparison of nanoparticles prepared by either chemical reduction, liquid flame spray (LFS), or plasma arc demonstrate how the type of manufacturing process used for the nanoscale silver can change the resulting life cycle impact of the sock product. The magnitude of this impact will depend on the type of process used to manufacture the nanoscale silver, with LFS having the most impact because of the need for large quantities of hydrogen and oxygen. Although the increased impacts for a single nanoproduct may be relatively small, the added environmental load can actually be a significant quantity when considered at the regional or global production level.

AB For several decades, dinitrogen pentoxide (N2O5) has been recognized as an important reactive intermediate in the atmospheric chemistry of nitrogen oxides and nitrate aerosol, especially during nighttime. However, due to the lack of ambient observations of N2O5, the nocturnal nitrogen oxide chemistry could not be quantified until recent years. The objective of the present article is to assess the current state-of-the-art knowledge of N2O5 dynamics within the tropospheric aerosol. An up-to-date summary of N2O5 chemistry and major loss mechanisms are provided. Furthermore, techniques for measuring ambient N2O5 and an overview of typical N2O5 levels in the troposphere are described. In addition, model representations of N2O5 chemistry are reviewed along with key features of N2O5 vertical profiles based on numerical simulations. Lastly, the article provides the outstanding uncertainties and needs for further research into the atmospheric chemistry of N2O5. These include the need for better characterization of N2O5 heterogeneous uptake under temperature conditions characteristic of mid-and high-latitude winter seasons; greater understanding of the influence of individual aerosol components on N2O5 uptake and representation of these components in atmospheric models; and comprehensive descriptions of nighttime vertical profiles of N2O5 and related pollutants.

AB This article empirically demonstrates the use of fine resolution satellite-based aerosol optical depth (AOD) to develop time and space resolved estimates of ambient particulate matter (PM) <= 2.5 mu m and <= 10 mu m in aerodynamic diameters (PM2.5 and PM10, respectively). AOD was computed at three different spatial resolutions, i.e., 2 km (means 2 km x 2 km area at nadir), 5 km, and 10 km, by using the data from MODerate Resolution Imaging Spectroradiometer (MODIS), aboard the Terra and Aqua satellites. Multiresolution AOD from MODIS (AOD(MODIS)) was compared with the in situ measurements of AOD by NASA's AErosol RObotic NETwork (AERONET) sunphotometer (AOD(AERONET)) at Bondville, IL, to demonstrate the advantages of the fine resolution AODMODIS over the 10-km AOD(MODIS), especially for air quality prediction. An instrumental regression that corrects AOD(MODIS) for meteorological conditions was used for developing a PM predictive model.
The 2-km AOD(MODIS) aggregated within 0.025 degrees and 15-min intervals shows the best association with the in situ measurements of AOD(AERONET). The 2-km AOD(MODIS) seems more promising to estimate time and space resolved estimates of ambient PM than the 10-km AOD(MODIS), because of better location precision and a significantly greater number of data points across geographic space and time. Utilizing the collocated AOD(MODIS) and PM data in Cleveland, OH, a regression model was developed for predicting PM for all AOD(MODIS) data points. Our analysis suggests that the slope of the 2-km AOD(MODIS) (instrumented on meteorological conditions) is close to unity with the PM monitored on the ground. These results should be interpreted with caution, because the slope of AOD(MODIS) ranges from 0.52 to 1.72 in the site-specific models. In the cross validation of the overall model, the root mean square error (RMSE) of PM10 was smaller (2.04 mu g/m(3) in overall model) than that of PM2.5 (2.5 mu g/m(3)). The predicted PM in the AODMODIS data (similar to 2.34 million data points) was utilized to develop a systematic grid of daily PM at 5-km spatial resolution with the aid of spatiotemporal Kriging.

AB Developmental neurotoxicity testing (DNT) is perceived by many stakeholders to be an area in critical need of alternative methods to current animal testing protocols and guidelines. An immediate goal is to develop test methods that are capable of screening large numbers of chemicals. This document provides recommendations for developing alternative DNT approaches that will generate the type of data required for evaluating and comparing predictive capacity and efficiency across test methods and laboratories. These recommendations were originally drafted to stimulate and focus discussions of alternative testing methods and models for DNT at the TestSmart DNT II meeting (http://caat.jhsph.edu/programs/workshops/dnt2.html) and this document reflects critical feedback from all stakeholders that participated in this meeting. The intent of this document is to serve as a catalyst for engaging the research community in the development of DNT alternatives and it is expected that these recommendations will continue to evolve with the science.

AB The European cosmetics legislation foresees a review in 2011 and possible postponement of the 2013 marketing ban to enforce the testing ban for systemic and repeated-dose animal tests. For this purpose, a 119-page report commissioned by the European Commission was published recently. Here, a group of
17 independent experts from the US, Europe, and Japan was brought together to evaluate the report. The expert panel strongly endorsed the report and its conclusions. A number of important options not considered were identified; these do not, however, affect the overall conclusions regarding the current lack of availability of a full replacement, especially for the areas of repeated dose toxicity, carcinogenicity testing, and reproductive toxicity, though a roadmap for change is emerging. However, some of these options may provide adequate data for replacement of some animal studies in the near future pending validation. Various recommendations expand the original report. The reviewers agree with the report that there is greater promise in the short term for the areas of sensitization and toxicokinetics. Additional opportunities lie in more global collaborations and the inclusion of other industry sectors.

AB In October 2010, a group of experts met as part of the transatlantic think tank for toxicology (t(4)) to exchange ideas about the current status and future of safety testing of nanomaterials. At present, there is no widely accepted path forward to assure appropriate and effective hazard identification for engineered nanomaterials. The group discussed needs for characterization of nanomaterials and identified testing protocols that incorporate the use of innovative alternative whole models such as zebrafish or C. elegans, as well as in vitro or alternative methods to examine specific functional pathways and modes of action. The group proposed elements of a potential testing scheme for nanomaterials that works towards an integrated testing strategy, incorporating the goals of the NRC report Toxicity Testing in the 21(st) Century: A Vision and a Strategy by focusing on pathways of toxic response, and utilizing an evidence-based strategy for developing the knowledge base for safety assessment. Finally, the group recommended that a reliable, open, curated database be developed that interfaces with existing databases to enable sharing of information.

AB Comparing agricultural cohorts with the general population is challenging because the general healthiness of farmers may mask potential adverse health effects of farming. Using data from the Agricultural Health Study, a cohort of 89,656 pesticide applicators and their spouses (N = 89, 656) in North Carolina and Iowa, the authors computed standardized mortality ratios (SMRs) comparing deaths from time of the enrollment (1993-1997) through 2007 to state-specific rates. To compensate for the cohort's overall healthiness, relative SMRs were estimated by calculating the SMR for each cause relative to the SMR for all other causes. In 1,198,129 person-years of follow-up, 6,419 deaths were observed. The all-cause mortality rate was less than expected (SMRapplicators = 0.54, 95% confidence interval (CI): 0.52, 0.55; SMRspouses = 0.52, 95% CI: 0.50, 0.55). SMRs for all cancers, heart disease, and diabetes were significantly below 1.0. In contrast, applicators experienced elevated numbers of machine-related deaths (SMR = 4.15, 95% CI: 3.18, 5.31), motor vehicle nontraffic accidents (SMR = 2.80, 95% CI: 1.81, 4.14), and collisions with objects (SMR = 2.12, 95% CI: 1.25, 3.34). In the relative SMR analysis for applicators, the relative mortality ratio was elevated for lymphohematopoietic cancers, melanoma, and digestive system, prostate, kidney, and brain cancers. Among spouses, relative SMRs exceeded 1.0 for lymphohematopoietic cancers and malignancies of the digestive system, brain, breast, and ovary. Unintentional fatal injuries remain an important risk for farmers; mortality ratios from several cancers were elevated relative to other causes.

AB Objectives. The indoor environment has not been fully incorporated into the environmental justice dialogue. To inform strategies to reduce disparities, we developed a framework to identify the individual and place-based drivers of indoor environment quality.
Methods. We reviewed empirical evidence of socioeconomic disparities in indoor exposures and key determinants of these exposures for air pollutants, lead, allergens, and semivolatile organic compounds. We also used an indoor air quality model applied to multifamily housing to illustrate how nitrogen dioxide (NO(2)) and fine particulate matter (PM(2.5)) vary as a function of factors known to be influenced by socioeconomic status.
Results. Indoor concentrations of multiple pollutants are elevated in low-socioeconomic status households. Differences in these exposures are driven by the combined influences of indoor sources, outdoor sources, physical structures, and residential activity patterns. Simulation models confirmed indoor sources' importance in determining indoor NO(2) and PM(2.5) exposures and showed the influence of household-specific determinants.
Conclusions. Both theoretical models and empirical evidence emphasized that disparities in indoor environmental exposure can be significant. Understanding key determinants of multiple indoor exposures can aid in developing policies to reduce these disparities. (Am J Public Health. 2011;101:S238-S245. doi:10.2105/AJPH.2011.300119)

AB Objectives. An environmental quality index (EQI) for all counties in the United States is under development to explore the relationship between environmental insults and human health. The EQI is potentially useful for investigators researching health disparities to account for other concurrent environmental conditions. This article focused on the identification and assessment of data sources used in developing the EQI. Data source strengths, limitations, and utility were addressed.
Methods. Five domains were identified that contribute to environmental quality: air, water, land, built, and sociodemographic environments. An inventory of possible data sources was created. Data sources were evaluated for appropriate spatial and temporal coverage and data quality.
Results. The overall data inventory identified multiple data sources for each domain. From the inventory (187 sources, 617 records), the air, water, land, built environment, and sociodemographic domains retained 2, 9, 7, 4, and 2 data sources for inclusion in the EQI, respectively. However, differences in data quality, geographic coverage, and data availability existed between the domains.
Conclusions. The data sources identified for use in the EQI may be useful to researchers, advocates, and communities to explore specific environmental quality questions. (Am J Public Health. 2011;101:S277-S285. doi:10.2105/AJPH.2011.300184)

AB In March 2010, the Environmental Protection Agency (EPA) collaborated with government and nongovernmental organizations to host a groundbreaking symposium, "Strengthening Environmental Justice Research and Decision Making: A Symposium on the Science of Disproportionate Environmental Health Impacts."
The symposium provided a forum for discourse on the state of scientific knowledge about factors identified by EPA that may contribute to higher burdens of environmental exposure or risk in racial/ethnic minorities and low-income populations. Also featured were discussions on how environmental justice considerations may be integrated into EPA's analytical and decision-making frameworks and on research needs for advancing the integration of environmental justice into environmental policymaking.
We summarize key discussions and conclusions from the symposium and briefly introduce the articles in this issue. (Am J Public Health. 2011;101:S19-S26. doi:10.2105/AJPH.2011.300368)

AB Objectives. Our primary objective was to provide higher quality, more accessible science to address challenges of characterizing local-scale exposures and risks for enhanced community-based assessments and environmental decision-making.
Methods. After identifying community needs, priority environmental issues, and current tools, we designed and populated the Community-Focused Exposure and Risk Screening Tool (C-FEAST) in collaboration with stakeholders, following a set of defined principles, and considered it in the context of environmental justice.
Results. C-FEAST is a geographic information system and resource access Web tool under development for supporting multimedia community assessments. Community-level exposure and risk research is being conducted to address specific local issues through case studies.
Conclusions. C-FERST can be applied to support environmental justice efforts. It incorporates research to develop community-level data and modeled estimates for priority environmental issues, and other relevant information identified by communities. Initial case studies are under way to refine and test the tool to expand its applicability and transferability. Opportunities exist for scientists to address the many research needs in characterizing local cumulative exposures and risks and for community partners to apply and refine C-FERST.

AB Microcystins are cyclic heptapeptide toxins produced by a number of genera of cyanobacteria. They are ubiquitous in bodies of water worldwide and pose significant hazard to human, plant, and animal health. Microcystins are primarily hepatotoxins known to inhibit serine-threonine phosphatases leading to the disruption of cascade of events important in the regulation and control of cellular processes. Covalent binding of microcystins with phosphatases is thought to be responsible for the cytotoxic and genotoxic effects of microcystins. In addition, microcystins can trigger oxidative stress in cells resulting in necrosis or apoptosis. Their cyclic structure and novel amino acids enhance their stability and persistence in the environment. Humans are primarily exposed to microcystins via drinking water consumption and accidental ingestion of recreational water. Recreational exposure by skin contact or inhalation to microcystins is now recognized to cause a wide range of acute illnesses which can be life-threatening.
Microcystins are primarily degraded by microorganisms in the environment, while sunlight can cause the isomerization of the double bonds and hydroxylation in the presence of pigments. Attempts to utilize these organisms in sand and membrane filters to treat water contaminated with microcystins showed complete removal and detoxification. Conventional water treatment processes may not fully eliminate microcystins when there are high levels of organic compounds especially during harmful bloom events. Combination of conventional and advanced oxidation technologies can potentially remove 100% of microcystins in water even in turbid conditions. This review covers selected treatment technologies to degrade microcystins in water.

AB Selected comparisons of water quality and biological properties in lakewide samplings of the early 1970s and 2005-2006 illustrate a range of ecological changes within Lake Superior over the last three decades. Comparisons depict warmed surface layers, and increased chloride and nitrate concentrations-confirming trends described in recent literature. Our comparisons also depict some spatial dimensions of change, showing vertical and horizontal patterns throughout the lake as a function of depth and from shallow to deepest waters. The selected physico-chemical examples speak to different scales of source drivers for change (from local, to basinwide, and even global) and highlight a lake in which some fundamental properties have been influenced in a short period relative to its long flushing time (similar to 170 years). One legacy of the past 30 years of study seems clear: the notion that Lake Superior, due to its vastness, is resistant to environmental forcing and very slow to change, has been modified. We use two important biological components to evaluate change and also to contrast biological distributions, highlighting that some fundamental aspects of food webs vary with depth. Reflecting on these observations, we offer a perspective on how well we keep track of the condition and functioning of the lake, and how we might improve assessments to more actively inform management. Without more frequent biological sampling across all depth zones of the lake, there will continue to be limited ability to assess the nature and causes of ecological change, even when some changes are detected. Knowing that physico-chemical changes can occur relatively quickly (within decades), that the mechanisms for change can be expressed over different spatial dimensions of the lake, and that biology is distributed heterogeneously over these spatial dimensions, we argue the need to increase the degree (the spatial comprehensiveness, frequency, and integration of components) to which the lake is assessed.

AB Spatial variation is well known to exist in water quality parameters of the Great Lakes nearshore; however, strong patterns for extended reaches also have been observed and found to be robust across seasonal time frames. Less is known about robustness of inter-annual variation within parameters for water quality in the nearshore. We have conducted high-resolution surveys with towed electronic instrumentation in nearshore areas of Lake Superior and have combined several seasons (2001-2005) of measurements from multiple research efforts to investigate how spatial variation compares across years. The combined survey tows ranged across approximately 1200 km of Lake Superior's south shore. In addition to the survey tracks, we also sampled fixed stations to collect calibration data and other parameters not observed by the in situ electronic sensors. The towed sensor data provided information on the spatial and temporal variability of water quality parameters along the nearshore. We found a consistent spatial pattern over time along the south shore of Lake Superior. Nearshore water quality parameters were analyzed with respect to landscape characteristics of the adjacent watersheds (US only) using multivariate stepwise regressions and found to correlate to landscape characterization. The stressor categories of landscape character that best described the nearshore parameters were agriculture-chemical usage and land-cover attributes. Peak nearshore values corresponded with landscape position that had the most altered landuse character (e. g. Duluth/Superior region). The landscape character appears to drive and maintain the spatial pattern in nearshore water quality parameters.

AB Biological indicators can be used both to estimate ecological condition and to suggest plausible causes of ecosystem degradation across the U.S. Great Lakes coastal region. Here we use data on breeding bird, diatom, fish, invertebrate, and wetland plant communities to develop robust indicators of ecological condition of the U.S. Lake Superior coastal zone. Sites were selected as part of a larger, stratified random design for the entire U.S. Great Lakes coastal region, covering gradients of anthropogenic stress defined by over 200 stressor variables (e.g. agriculture, altered land cover, human populations, and point source pollution). A total of 89 locations in Lake Superior were sampled between 2001 and 2004 including 31 sites for stable isotope analysis of benthic macroinvertebrates, 62 sites for birds, 35 for diatoms, 32 for fish and macroinvertebrates, and 26 for wetland vegetation. A relationship between watershed disturbance metrics and (15)N levels in coastal macroinvertebrates confirmed that watershed-based stressor gradients are expressed across Lake Superior's coastal ecosystems, increasing confidence in ascribing causes of biological responses to some landscape activities. Several landscape metrics in particular-agriculture, urbanization, human population density, and road density-strongly influenced the responses of indicator species assemblages. Conditions were generally good in Lake Superior, but in some areas watershed stressors produced degraded conditions that were similar to those in the southern and eastern U.S. Great Lakes. The following indicators were developed based on biotic responses to stress in Lake Superior in the context of all the Great Lakes: (1) an index of ecological condition for breeding bird communities, (2) diatom-based nutrient and solids indicators, (3) fish and macroinvertebrate indicators for coastal wetlands, and (4) a non-metric multidimensional scaling for wetland plants corresponding to a cumulative stress index. These biotic measures serve as useful indicators of the ecological condition of the Lake Superior coast; collectively, they provide a baseline assessment of selected biological conditions for the U.S. Lake Superior coastal region and prescribe a means to detect change over time.

AB Quantifying gradients of anthropogenic stress can inform the development of sample designs, provide an important covariate in modeling relationships of response variables, identify reference and highly-disturbed sites, and provide a baseline and guidance to restoration and remediation efforts. We describe development of SumRel, a composite index of anthropogenic stress, for the U.S. and Canadian Lake Superior basin. Key elements of the project include development of high-resolution watersheds throughout the basin, summarization of the major point and non-point stressors within these watersheds, and creation of tools for scaling watersheds and stressor summaries. SumRel was calculated at two spatial scales: for high resolution subcatchments within the Lake Superior basin (mean watershed area = 93 ha) and for coastal watersheds of Lake Superior. An assessment of subcatchments within Minnesota's St. Louis River watershed showed a correlation between the degree of disturbance, as indicated by SumRel, and impaired water quality, as evidenced by in-stream conductivity. These data and tools allow identification and visualization of reference and highly-disturbed sites at multiple spatial scales, providing decision support for individual agency and binational monitoring, assessment and restoration initiatives across the Lake Superior basin.

AB Trophic linkages of larval fish in Lake Superior coastal habitats can be identified using naturally occurring differences in the stable isotope ratios of nitrogen ((15)N: (14)N, delta(15)N) and carbon ((13)C: (12)C, delta(13)C). We measured (13)C and (15)N values in common fish larvae weekly during spring run-off (late-April to mid-July) in the hydrologically complex drowned river mouth of the St. Louis River, the second largest tributary to Lake Superior. For all species, delta(13)C was increasingly negative with increasing weight as the fish developed from the yolk-sac stage, during which they possess a maternally-derived isotopic signature, to an exogenously feeding larvae. Trends in delta(15)N with increasing weight varied among species; an increase, decrease, and no change in delta(15)N were observed. A weight-based stable isotope turnover function modeled well the observed changes in delta(13)C and delta(15)N. In general, fish obtained a constant signature after a 10-fold gain in body mass, implying their tissue was at isotopic equilibrium with their diet. Difference between yolk-sac and larvae delta(13)C and delta(15)N revealed distinct patterns in larval origin and settlement. Based on the species analyzed, we identify two specific Lake Superior coastal wetland-dependent fish early life histories that incorporate habitat use, movement, and trophic dynamics. This study thus provides a methodological approach that can potentially help resolve interactions between watershed character, coastal productivity, and Lake Superior that are of significance to the lake's fisheries.

AB The amount of excess fixed nitrogen removed from the freshwater aquatic nitrogen cycle, particularly by freshwater wetlands, through denitrification (DNF) is largely unknown. Typically, DNF rates increase within sediments that have higher organic content and a source of sufficient NO(3)(-), in this context we measured DNF in organic-rich sediments of Lost Creek wetland on the south shore of Lake Superior, where NO(3)(-) concentrations have increased dramatically over the last century. The concentrations of N(2), O(2), and Ar were determined on intact water-sediment cores. Denitrification and respiration rates were determined using membrane inlet mass spectrometry and N(2):Ar and O(2):Ar ratios. Nitrogen flux rates measured in August 2000 and 2001 using overlying ambient wetland water, Lake Superior water, and nitrate augmented wetland water ranged from <10 to 78 mu mol N m(-2) h(-1). These rates are low compared to those published for a variety of wetland and aquatic ecosystems. Nonetheless these are the first DNF measurements we know of to assess natural rates in the Lake Superior Basin and they help quantify a missing piece of wetland and lake nitrogen transformations.

AB Consistent, repeatable and broadly applicable land use, land cover data is needed across the Lake Superior basin to facilitate ecosystem condition assessment and trend analysis. Such a data set collected regularly through time could inform and focus field monitoring efforts, and help prioritize restoration and mitigation efforts. Unfortunately, few data sets exist that are bi-nationally consistent in time, classification method, or resolution. To this end, we integrated land cover data across both the Canadian (Ontario Provincial Land Cover data) and US portions (National Land Cover Data) of the Lake Superior basin for two time steps (approximately 1992 and 2001) roughly one decade apart. After harmonizing landcover classes across the two datasets we compared the explicit amount and relative amount (total hectares and proportion of each area as percents) for each of the common land cover classes that occurred across the two time steps for the entire Lake Superior basin, for the U.S. portion of the Lake Superior basin only, and for the Canadian portion of the Lake Superior basin only. We also compared land cover change for the entire basin within a 1 km and a 10 km buffer of the Great Lakes shoreline. We then summarized and compared these land cover types for each time period across a common set of watersheds derived from elevation data (Hollenhorst et al., 2007) for the entire Lake Superior basin. This allowed us to identify and quantify the types of change occurring generally across the entire basin, more specifically across both the U. S. and Canadian portions of the basin, and more explicitly for near coastal areas and watersheds across the entire basin. Noteworthy changes were detected across the basin, particularly an increase in mixed forest types and a corresponding decrease in coniferous forest types.

AB Coastal wetlands are important contributors to large-lake productivity and biodiversity and mediators of lake - watershed interactions. This study explores whether the size of the watershed in which coastal wetlands are embedded (a measure of strength of connection to the terrestrial landscape) influences their background condition and response to anthropogenic landuse. Water quality, substrate, vegetation structure, and composition of zoobenthos, turtles, crayfish, and fish were characterized in 32 Lake Superior coastal wetlands in the summers of 2000-2001, and related to watershed size categories via ANOVA and to watershed development (percent agricultural and urban landuse) via linear regression. Lake Superior coastal wetlands had relatively low levels of watershed development - apparently not enough to significantly alter fish composition. However, watershed development was associated with significant changes in substrate, turbidity, plant structure, and zoobenthos, and in most cases these effects were stronger in wetlands having big rather than small watersheds. An alternate classification contrasting exposure to versus protection from river influences was not effective at resolving responses to watershed development. Watershed size had little effect on background conditions in minimally disturbed wetlands, although turtles were more abundant in large-watershed wetlands. The role of watershed size in mediating responses to landuse merits further study, but our findings suggest that receiving inflows from bigger watersheds affects coastal wetlands primarily by amplifying transmission of disturbance rather than via direct impacts of flow.

AB As part of the Environmental Monitoring and Assessment Program for Great River Ecosystems (EMAP-GRE), sediment samples were collected from 447 randomly selected littoral sites along the main channels of the Ohio, Missouri, and Upper Mississippi Rivers between 2004 and 2006. Toxicity of these sediment samples was measured using a 7-day Hyalella azteca survival and growth test. Sixty-five sites (14.5%) exhibited lethal toxicity, and 130 sites (29.1%) exhibited decreased growth. In the EMAP-GRE probabilistic sampling design, each sampled site had a weight associated with it that determined the length (and proportion) of the river represented by that sample point in the population. Weighted whole-river estimates indicated that of the 4721 river km sampled, sediment from 15.9 +/- 3.0% of the river (752 +/- 50 km) were lethally toxic, 27.4 +/- 3.5% (1289 +/- 57 km) were toxic by way of growth inhibition, and 40.0 +/- 3.7% (1887 +/- 68 km) exhibited either lethal or growth toxicity. Selected toxic samples were analyzed for 21 pesticides, 20 polychlorinated biphenyl congeners, and 6 polybrominated diphenyl ether congeners. For all of the samples tested, the concentration levels of these analytes were mostly lower than known toxicity thresholds, and neither unionized ammonia concentration nor osmotic stress (as measured by conductivity) could account for the toxicity found in sediments. The spatial pattern of sediment toxicity cannot be readily explained by urbanization or agricultural land use at the subcatchment scale. We speculate that the distribution of toxic sediment is more likely due to a combination of localized sources, including polluted tributaries, and the redistribution of contaminated sediments from upriver. The sediment toxicity results from this study will be used, in combination with other sediment, biologic, and habitat metrics and indicators collected in the EMAP-GRE study, to help interpret and assess the condition of the Ohio, Upper Mississippi, and Missouri Rivers.

AB Respiratory health is an important component of the ability to perform physically demanding work. The authors assessed respiratory symptom prevalence among Latino farmworkers engaged in crop production, and investigated work activities as risk factors for respiratory symptoms. During June to September 2008, 122 farmworkers completed up to 3 questionnaires. The authors estimated associations between work activities and wheezing symptoms using alternating logistic regression, controlling for age and smoking. At the first data collection, 29 (24%) farmworkers reported ever wheezing and 10 (8%) reported wheezing within the past month. Though not statistically significant, the odds of wheezing were elevated for individuals who reported performing tobacco-related work in the last 3 days. The odds were decreased among individuals who reported harvesting activities (odds ratio: 0.3, 95% confidence interval: 0.1, 1.0). Among Latino farmworkers, respiratory symptoms may be associated with work activities.

AB Introduction: The objective of this study is to determine if multiple systemic autoimmune diseases (SAID) share gene expression pathways that could provide insights into pathogenic mechanisms common to these disorders.
Methods: RNA microarray analyses (Agilent Human 1A(V2) 20K oligo arrays) were used to quantify gene expression in peripheral blood cells from 20 monozygotic (MZ) twin pairs discordant for SAID. Six affected probands with systemic lupus erythematosus (SLE), six with rheumatoid arthritis (RA), eight with idiopathic inflammatory myopathies (IIM), and their same-gendered unaffected twins, were enrolled. Comparisons were made between discordant twin pairs and these were also each compared to 40 unrelated control subjects (matched 2: 1 to each twin by age, gender and ethnicity) using statistical and molecular pathway analyses. Relative quantitative PCR was used to verify independently measures of differential gene expression assessed by microarray analysis.
Results: Probands and unrelated, matched controls differed significantly in gene expression for 104 probes corresponding to 92 identifiable genes (multiple-comparison adjusted P values < 0.1). Differentially expressed genes involved several overlapping pathways including immune responses (16%), signaling pathways (24%), transcription/translation regulators (26%), and metabolic functions (15%). Interferon (IFN)-response genes (IFI27, OASF, PLSCR1, EIF2AK2, TNFAIP6, and TNFSF10) were up-regulated in probands compared to unrelated controls. Many of the abnormally expressed genes played regulatory roles in multiple cellular pathways. We did not detect any probes expressed differentially in comparisons among the three SAID phenotypes. Similarly, we found no significant differences in gene expression when comparing probands to unaffected twins or unaffected twins to unrelated controls. Gene expression levels for unaffected twins appeared intermediate between that of probands and unrelated controls for 6535 probes (32% of the total probes) as would be expected by chance. By contrast, in unaffected twins intermediate ordering was observed for 84 of the 104 probes (81%) whose expression differed significantly between probands and unrelated controls.
Conclusions: Alterations in expression of a limited number of genes may influence the dysregulation of numerous, integrated immune response, cell signaling and regulatory pathways that are common to a number of SAID. Gene expression profiles in peripheral blood suggest that for genes in these critical pathways, unaffected twins may be in a transitional or intermediate state of immune dysregulation between twins with SAID and unrelated controls, perhaps predisposing them to the development of SAID given the necessary and sufficient environmental exposures.

AB Regional trans-boundary air pollution has become an important issue in the field of air pollution modeling. This paper presents the results of the implementation of the MM5-CMAQ modeling system in the Yangtze River Delta (YRD) for the months of January and July of 2004. The meteorological parameters are obtained by using the MM5 model. A new regional emission inventory with spatial and temporal allocations based on local statistical data has been developed to provide input emissions data to the MM5-CMAQ modeling system. The pollutant concentrations obtained from the MM5-CMAQ modeling system have been compared with observational data from the national air pollution monitoring network. It is found that air quality in winter in the YRD is generally worse than in summer, due mainly to unfavorable meteorological dispersion conditions. In winter, the pollution transport from Northern China to the YRD reinforces the pollution caused by large local emissions. The monthly average concentration of SO2 in the YRD is 0.026 +/- 0.011 mg m(-3) in January and 0.017 +/- 0.009 mg m(-3) in July. Monthly average concentrations of NO2 in the YRD in January and July are 0.021 +/- 0.009 mg m(-3), and 0.014 +/- 0.008 mg m(-3), respectively. The monthly average concentration of PM10 in the YRD is 0.080 +/- 0.028 mg m(-3) in January and 0.025 +/- 0.015 mg m(-3) in July. Visibility is also a problem, with average deciview values of 26.4 +/- 2.95 dcv in winter and 17.6 +/- 3.3 dcv in summer. The ozone concentration in the downtown area of a city like Zhoushan can be very high, with the highest simulated value reaching 0.24 mg m(-3). In January, the monthly average concentration of O-3 in the YRD is 0.052 +/- 0.011 mg m(-3), and 0.054 +/- 0.008 mg m(-3) in July. Our results show that ozone and haze have become extremely important issues in the regional air quality. Thus, regional air pollution control is urgently needed to improve air quality in the YRD.

AB The secondary organic aerosol (SOA) yield of beta-caryophyllene photooxidation is enhanced by aerosol acidity. In the present study, the influence of aerosol acidity on the chemical composition of beta-caryophyllene SOA is investigated using ultra performance liquid chromatography/electrospray ionization-time-of-flight mass spectrometry (UPLC/ESI-TOFMS). A number of first-, second- and higher-generation gas-phase products having carbonyl and carboxylic acid functional groups are detected in the particle phase. Particle-phase reaction products formed via hydration and organosulfate formation processes are also detected. Increased acidity leads to different effects on the abundance of individual products; significantly, abundances of organosulfates are correlated with aerosol acidity. To our knowledge, this is the first detection of organosulfates and nitrated organosulfates derived from a sesquiterpene. The increase of certain particle-phase reaction products with increased acidity provides chemical evidence to support the acid-enhanced SOA yields. Based on the agreement between the chromatographic retention times and accurate mass measurements of chamber and field samples, three beta-caryophyllene products (i.e., beta-nocaryophyllon aldehyde, beta-hydroxynocaryophyllon aldehyde, and beta-dihydroxynocaryophyllon aldehyde) are suggested as chemical tracers for beta-caryophyllene SOA. These compounds are detected in both day and night ambient samples collected in downtown Atlanta, GA and rural Yorkville, GA during the 2008 August Mini-Intensive Gas and Aerosol Study (AMIGAS).

AB Data from the Interagency Monitoring of Protected Visual Environments (IMPROVE) network are used to estimate organic mass to organic carbon (OM/OC) ratios across the United States by extending previously published multiple regression techniques. Our new methodology addresses common pitfalls of multiple regression including measurement uncertainty, colinearity of covariates, dataset selection, and model selection. As expected, summertime OM/OC ratios are larger than wintertime values across the US with all regional median OM/OC values tightly confined between 1.80 and 1.95. Further, we find that OM/OC ratios during the winter are distinctly larger in the eastern US than in the West (regional medians are 1.58, 1.64, and 1.85 in the great lakes, southeast, and northeast regions, versus 1.29 and 1.32 in the western and central states). We find less spatial variability in long-term averaged OM/OC ratios across the US (90% of our multiyear regressions estimate OM/OC ratios between 1.37 and 1.94) than previous studies (90% fell between 1.30 and 2.10). We attribute this difference largely to the inclusion of EC as a covariate in previous regression studies. Due to the colinearity of EC and OC, we find that up to one-quarter of the OM/OC estimates in a previous study are biased low. Assumptions about OC measurement artifacts add uncertainty to our estimates of OM/OC. In addition to estimating OM/OC ratios, our technique reveals trends that may be contrasted with conventional assumptions regarding nitrate, sulfate, and soil across the IMPROVE network. For example, our regressions show pronounced seasonal and spatial variability in both nitrate volatilization and sulfate neutralization and hydration.

AB Statistical response surface methodology (RSM) is successfully applied for a Community Multi-scale Air Quality model (CMAQ) analysis of ozone sensitivity studies. Prediction performance has been demonstrated through cross validation, out-of-sample validation and isopleth validation. Sample methods and key parameters, including the maximum numbers of variables involved in statistical interpolation and training samples have been tested and selected through computational experiments. Overall impacts from individual source categories which include local/regional NOx and VOC emission sources and NOx emissions from power plants for three megacities - Beijing, Shanghai and Guangzhou - were evaluated using an RSM analysis of a July 2005 modeling study. NOx control appears to be beneficial for ozone reduction in the downwind areas which usually experience high ozone levels, and NOx control is likely to be more effective than anthropogenic VOC control during periods of heavy photochemical pollution. Regional NOx source categories are strong contributors to surface ozone mixing ratios in three megacities. Local NOx emission control without regional involvement may raise the risk of increasing urban ozone levels due to the VOC-limited conditions. However, local NOx control provides considerable reduction of ozone in upper layers (up to 1 km where the ozone chemistry is NOx-limited) and helps improve regional air quality in downwind areas. Stricter NOx emission control has a substantial effect on ozone reduction because of the shift from VOC-limited to NOx-limited chemistry. Therefore, NOx emission control should be significantly enhanced to reduce ozone pollution in China.

AB As a component of fine particulate matter (PM2.5), black carbon (BC) is associated with premature human mortality. BC also affects climate by absorbing solar radiation and reducing planetary albedo. Several studies have examined the climate impacts of BC emissions, but the associated health impacts have been studied less extensively. Here, we examine the surface PM2.5 and premature mortality impacts of halving anthropogenic BC emissions globally and individually from eight world regions and three major economic sectors. We use a global chemical transport model, MOZART-4, to simulate PM2.5 concentrations and a health impact function to calculate premature cardiopulmonary and lung cancer deaths. We estimate that halving global anthropogenic BC emissions reduces outdoor population-weighted average PM2.5 by 542 ngm(-3) (1.8 %) and avoids 157 000 (95% confidence interval, 120 000-194 000) annual premature deaths globally, with the vast majority occurring within the source region. Most of these avoided deaths can be achieved by halving emissions in East Asia (China; 54 %), followed by South Asia (India; 31 %), however South Asian emissions have 50% greater mortality impacts per unit BC emitted than East Asian emissions. Globally, halving residential, industrial, and transportation emissions contributes 47 %, 35 %, and 15% to the avoided deaths from halving all anthropogenic BC emissions. These contributions are 1.2, 1.2, and 0.6 times each sector's portion of global BC emissions, owing to the degree of co-location with population globally. We find that reducing BC emissions increases regional SO4 concentrations by up to 28% of the magnitude of the regional BC concentration reductions, due to reduced absorption of radiation that drives photochemistry. Impacts of residential BC emissions are likely underestimated since indoor PM2.5 exposure is excluded. We estimate similar to 8 times more avoided deaths when BC and organic carbon (OC) emissions are halved together, suggesting that these results greatly underestimate the full air pollution-related mortality benefits of BC mitigation strategies which generally decrease both BC and OC. The choice of concentration-response factor and health effect thresholds affects estimated global avoided deaths by as much as 56% but does not strongly affect the regional distribution. Confidence in our results would be strengthened by reducing uncertainties in emissions, model parameterization of aerosol processes, grid resolution, and PM2.5 concentration-mortality relationships globally.

AB Time and size resolved data of trace elements were obtained from measurements with a rotating drum impactor (RDI) and subsequent X-ray fluorescence spectrometry. Trace elements can act as indicators for the identification of sources of particulate matter <10 mu m (PM(10)) in ambient air. Receptor modeling was performed with positive matrix factorization (PMF) for trace element data from an urban background site in Zurich, Switzerland. Eight different sources were identified for the three examined size ranges (PM(1-0.1), PM(2.5-1) and PM(10-2.5)): secondary sulfate, wood combustion, fire works, road traffic, mineral dust, de-icing salt, industrial and local anthropogenic activities. The major component was secondary sulfate for the smallest size range; the road traffic factor was found in all three size ranges. This trace element analysis is complemented with data from an Aerodyne high-resolution time-of-flight aerosol mass spectrometer (AMS), assessing the PM(1) fraction of organic aerosols. A separate PMF analysis revealed three factors related to three of the sources found with the RDI: oxygenated organic aerosol (OOA, related to inorganic secondary sulfate), hydrocarbon-like organic aerosol (HOA, related to road traffic) and biomass burning organic aerosol (BBOA), explaining 60 %, 22% and 17% of total measured organics, respectively. Since different compounds are used for the source classification, a higher percentage of the ambient PM(10) mass concentration can be apportioned to sources by the combination of both methods.

AB Presently only limited sets of tropospheric ammonia (NH3) measurements in the Earth's atmosphere have been reported from satellite and surface station measurements, despite the well-documented negative impact of NH3 on the environment and human health. Presented here is a detailed description of the satellite retrieval strategy and analysis for the Tropospheric Emission Spectrometer (TES) using simulations and measurements. These results show that: (i) the level of detectability for a representative boundary layer TES NH3 mixing ratio value is similar to 0.4 ppbv, which typically corresponds to a profile that contains a maximum level value of similar to 1 ppbv; (ii) TES NH3 retrievals generally provide at most one degree of freedom for signal (DOFS), with peak sensitivity between 700 and 900 mbar; (iii) TES NH3 retrievals show significant spatial and seasonal variability of NH3 globally; (iv) initial comparisons of TES observations with GEOS-CHEM estimates show TES values being higher overall. Important differences and similarities between modeled and observed seasonal and spatial trends are noted, with discrepancies indicating areas where the timing and magnitude of modeled NH3 emissions from agricultural sources, and to lesser extent biomass burning sources, need further study.

AB Previous global transcriptome and interactome analyses of copper-treated HepG2 cells identified hepatocyte nuclear factor 4 alpha (HNF4 alpha) as a potential master regulator of copper-responsive transcription. Copper exposure caused a decrease in the expression of HNF4 alpha at both mRNA and protein levels, which was accompanied by a decrease in the level of HNF4 alpha binding to its consensus DNA binding sequence. qRT-PCR and RNAi studies demonstrated that changes in HNF4 alpha expression ultimately affected the expressions of its down-stream target genes. Analysis of upstream regulators of HNF4 alpha expression, including p53 and ATF3, showed that copper caused an increase in the steady-state levels of these proteins. These results support a model for copper-responsive transcription in which the metal affects ATF3 expression and stabilizes p53 resulting in the down-regulation of HNF4 alpha expression. In addition, copper may directly affect p53 protein levels. The suppression of HNF4 alpha activity may contribute to the molecular mechanisms underlying the physiological and toxicological consequences of copper toxicity in hepatic-derived cells.

AB There is a large literature showing the detrimental effects of prenatal smoking on birth and childhood health outcomes. It is somewhat unclear, though, whether these effects are causal or reflect other characteristics and choices by mothers who choose to smoke that may also affect child health outcomes or biased reporting of smoking. In this paper, we use genetic markers that predict smoking behaviors as instruments to address the endogeneity of smoking choices in the production of birth and childhood health outcomes. Our results indicate that prenatal smoking produces more dramatic declines in birth weight than estimates that ignore the endogeneity of prenatal smoking, which is consistent with previous studies with non-genetic instruments. We use data from two distinct samples from Norway and the United States with different measured instruments and find nearly identical results. The study provides a novel application that can be extended to study several behavioral impacts on health and social and economic outcomes.

AB The microbial composition of concrete biofilms within wastewater collection systems was studied using molecular assays. SSU rDNA clone libraries were generated from 16 concrete surfaces of manholes, a combined sewer overflow, and sections of a corroded sewer pipe. Of the 2457 sequences analyzed, alpha-, beta-, gamma-, and delta-Proteobacteria represented 15%, 22%, 11%, and 4% of the clones, respectively. beta-Proteobacteria (47%) sequences were more abundant in the pipe crown than any of the other concrete surfaces. While 178 to 493 Operational Taxonomic Units (OTUs) were associated with the different concrete samples, only four sequences were shared among the different clone libraries. Bacteria implicated in concrete corrosion were found in the clone libraries while archaea, fungi, and several bacterial groups were also detected using group-specific assays. The results showed that concrete sewer biofilms are more diverse than previously reported. A more comprehensive molecular database will be needed to better study the dynamics of concrete biofilms.

AB The capacity for volatile isoprenoid production under standardized environmental conditions at a certain time (E-S, the emission factor) is a key characteristic in constructing isoprenoid emission inventories. However, there is large variation in published E-S estimates for any given species partly driven by dynamic modifications in E-S due to acclimation and stress responses. Here we review additional sources of variation in E-S estimates that are due to measurement and analytical techniques and calculation and averaging procedures, and demonstrate that estimations of E-S critically depend on applied experimental protocols and on data processing and reporting. A great variety of experimental setups has been used in the past, contributing to study-to-study variations in E-S estimates. We suggest that past experimental data should be distributed into broad quality classes depending on whether the data can or cannot be considered quantitative based on rigorous experimental standards. Apart from analytical issues, the accuracy of E-S values is strongly driven by extrapolation and integration errors introduced during data processing. Additional sources of error, especially in meta-database construction, can further arise from inconsistent use of units and expression bases of E-S. We propose a standardized experimental protocol for BVOC estimations and highlight basic meta-information that we strongly recommend to report with any E-S measurement. We conclude that standardization of experimental and calculation protocols and critical examination of past reports is essential for development of accurate emission factor databases.

AB The present study compares the dynamics in carbon (C) allocation of adult deciduous beech (Fagus sylvatica) and evergreen spruce (Picea abies) during summer and in response to seven-year-long exposure with twice-ambient ozone (O-3) concentrations (2xO(3)). Focus was on the respiratory turn-over and translocation of recent photosynthates at various positions along the stems, coarse roots and soils. The hypotheses tested were that (1) 2xO(3) decreases the allocation of recent photosynthates to CO2 efflux of stems and coarse roots of adult trees, and that (2) according to their different O3 sensitivities this effect is stronger in beech than in spruce.
Labeling of whole tree canopies was applied by releasing C-13 depleted CO2 (delta C-13 of -46.9 %) using a free-air stable carbon isotope approach. Canopy air delta C-13 was reduced for about 2.5 weeks by ca. 8 parts per thousand in beech and 6 parts per thousand in spruce while the increase in CO2 concentration was limited to about 110 mu l l(-1) and 80 mu l l(-1), respectively. At the end of the labeling period, delta C-13 of stem CO2 efflux and phloem sugars was reduced to a similar extend by ca. 3-4% (beech) and ca. 23%( spruce). The fraction of labeled C (f(E,) (new)) in stem CO2 efflux amounted to 0.3 to 0.4, indicating slow C turnover of the respiratory supply system in both species.
Elevated O-3 slightly stimulated the allocation of recently fixed photosynthates to stem and coarse root respiration in spruce (rejection of hypothesis I for spruce), but resulted in a significant reduction in C flux in beech (acceptance of hypotheses I and II). The distinct decrease in C allocation to beech stems indicates the potential of chronic O3 stress to substantially mitigate the C sink strength of trees on the long-term scale.

AB The fate of organic carbon (C) lost by erosion is not well understood in agricultural settings. Recent models suggest that wetlands and other small water bodies may serve as important long-term sinks of eroded C, receiving similar to 30% of all eroded material in the US. To better understand the role of seasonally-saturated wetlands in sequestering eroded C, we examined the spatial and temporal dynamics of C and sediment accumulation in a 13-year-old constructed wetland used to treat agricultural runoff. The fate of C sequestered within deposited sediment was modeled using point-sampling, remote sensing, and geostatistics. Using a spatially-explicit sampling design, annual net rates of sedimentation and above-ground biomass were measured during two contrasting years (vegetated (2004) vs. non-vegetated (2005)), followed by collection of sediment cores to the antecedent soil layer, representing 13 years of sediment and C accumulation. We documented high annual variation in the relative contribution of endogenous and exogenous C sources, as well as absolute rates of sediment and C deposition. This annual variation, however, was muted in the long-term (13 yr) sediment record, which showed consistent vertical patterns of uniform C distribution (similar to 14 g kg(-1)) and delta C-13 signatures in high depositional environments. This was in contrast to low depositional environments which had high levels of surface C enrichment (20-35 g kg(-1)) underlain by C depleted (5-10 g kg(-1)) sediments and an increasing delta C-13 signature with depth indicating increased decomposition. These results highlight the importance of sedimentation in physically protecting soil organic carbon and its role in controlling the long-term C concentration of seasonally-saturated wetland soils. While significant enrichment of surface sediments with endogenous C occurred in newly deposited sediment (i.e., 125 kgm(2) in 2004), fluctuating cycles of flooding and drying maintained the long-term C concentration at the same level as inflowing sediment (i.e., 14 g kg(-1)), indicating no additional long-term storage of endogenous C. These results demonstrate that constructed flow-through wetlands can serve as important sinks for eroded C and sediment in agricultural landscapes, however, additional C sequestration via enrichment from endogenous sources may be limited in seasonally-saturated wetlands due to rapid decomposition during drying cycles.

AB Current breakthroughs in green nanotechnology are capable of transforming many of the existing processes and products that enhance environmental quality, reduce pollution, and conserve natural and non-renewable resources. Successful use of metal nanoparticles and nanocomposites in various catalytic applications, electronics, biology and biomedical applications, material science, physics, environmental remediation and interdisciplinary fields as well as their toxicity essentially depends on the structural features such as size, shape, composition and the surface chemistry of nanomaterials. Moreover, to prolong the life span of metal nanoparticles and avoid undesired effects such as aggregation in aqueous solutions and organic solvents, to prevent contamination of the environment as well as to reuse and recycle nanoparticles, it is vital to select stabilizing agents and functionalization pathways that are environmentally friendly, non toxic and easy to implement. In recent years, stabilization and surface functionalization of metal nanoparticles became 'greener' to the extent that biocompatible stabilizing agents, e. g. biodegradable polymers and enzymes among others were introduced. These agents were able to produce a great variety of extremely stable spherical-, rod- or flower- shaped metal nanoparticles that opened up vast opportunities for their utilization and potential mass production. This review summarizes the state-of-the-art in the use of biocompatible and biodegradable homo- and copolymers as well as enzymes for the production of stable, environmentally benign, selective and active metal nanoparticles for desired applications.

AB Most current electrostatic surface complexation models describing ionic binding at the particle/water interface rely on the use of Poisson-Boltzmann (PB) theory for relating diffuse layer charge densities to diffuse layer electrostatic potentials. PB theory is known to contain a number of implicit assumptions whose significance in environmental applications is largely unknown. This study seeks to better quantify the impact of these assumptions by: (1) comparing potentials obtained from planar analytical solutions to the PB with those obtained from Hypernetted Chain (HNC) theory (Attard, 2006), (2) assessing the accuracy of the Ohshima et al. (1982) spherical approximate analytical solution to the PB equation by comparison with published numerical values (Loeb et al., 1961), and (3) comparing interfacial potential estimates obtained from the spherical approximate analytical solution to the PB equation at and adjacent to the particle surface with potential estimates obtained from the Entropic Balanced Surface Potential (EB) model (Loux, 1985; Loux and Anderson, 2001) and published potential estimates obtained from the Hypernetted Chain/Mean Spherical Approximation procedure (HNC/MSA; Gonzalez-Tovar and Lozada-Cassou, 1989). EB potential estimates were obtained assuming a surface volume thickness equal to the Bjerrum length (0.357 nm in a room temperature monovalent electrolyte solution). Findings from the study included: (1) the planar, surficial HNC estimates compared favourably with planar surficial PB relationships at charge densities equal to or less than 0.05C m(-2), (2) the Ohshima et al. (1982) approximate spherical analytical solution to the PB equation replicated the numerical charge density estimates required to obtain 72 datapoints over an e Psi/kT range of one to four with a maximum error of 3.37% and a coefficient of variation of 0.92%, (3) for a 0.1 mu m radius particle in a room temperature 0.01 M (1:1) ionic strength solution, potential estimates over a surface charge density range of 0 to 0.3C m(-2) occurred in the following order: Psi(HNC/MSA,R) > Psi(PB,R) > Psi(HNC/MSA,R+0.2125) (nm) > Psi P-B,P-R+0.2 nm similar to Psi(EB) > Psi(HNC/MSA,R+0.425 nm) similar to Psi(PB,R+0.4 nm) and (4) with 45 datapoints including both 1 mu m and 10 nm radius particles over an ionic strength range of 1.0 to 0.001 M, the PB potential estimates 0.2 nm from the particle surface (Psi(PB,R+0.2 nm)) closely tracked the corresponding EB estimates (Psi(EB)) with a 5.3% coefficient of variation. If one assumes that interfacial potential values adjacent to the particle surface are most relevant for describing environmental phenomena and that a 10% coefficient of variation in potential estimates is acceptable, then presumably any of the non-surficial charge/potential relationships would be useful below an absolute charge density of 0.125 C m(-2) (with monovalent electrolyte solutions).

AB Di-n-pentyl phthalate (DPP) is used mainly as a plasticizer in nitrocellulose. At high doses. DPP acts as a potent testicular toxicant in rats. We administered a single oral dose of 500 mg kg(-1) bw of DPP to adult female Sprague-Dawley rats (N = 9) and collected 24-h urine samples 1 d before and 24- and 48-h after DPP was administered to tentatively identify DPP metabolites that could be used as exposure biomarkers. At necropsy, 48 h after dosing, we also collected serum. The metabolites were extracted from urine or serum, resolved with high performance liquid chromatography, and detected by mass spectrometry. Two DPP metabolites, phthalic acid (PA) and mono(3-carboxypropyl) phthalate (MCPP), were identified by using authentic standards, whereas mono-n-pentyl phthalate (MPP), mono(4-oxopentyl) phthalate (MOPP), mono(4-hydroxypentyl) phthalate (MHPP), mono(4-carboxybutyl) phthalate (MCBP), mono(2-carboxyethyl) phthalate (MCEP), and mono-n-pentenyl phthalate (MPeP) were identified based on their full scan mass spectrometric fragmentation pattern. The omega - 1 oxidation product, MHPP, was the predominant urinary metabolite of DPP. The median urinary concentrations (mu g mL(-1)) of the metabolites in the first 24 h urine collection after DPP administration were 993 (MHPP), 168 (MCBP), 0.2 (MCEP), 222 (MPP), 47 (MOPP), 26 (PA), 16 (MPeP), and 9 (MCPP): the concentrations of metabolites in the second 24 h urine collection after DPP administration were significantly lower than in the first collection. We identified some urinary metabolic products in the serum, but at much lower levels than in urine. Because of the similarities in metabolism of phthalates between rats and humans, based on our results and the fact that MHPP can only be formed from the metabolism of DPP, MHPP would be the most adequate DPP exposure biomarker for human exposure assessment. Nonetheless, based on the urinary levels of MHPP, our preliminary data suggest that human exposure to DPP in the United States is rather limited. Published by Elsevier Ltd.

AB Macroporous membranes functionalized with ionizable macromolecules provide promising applications in high capacity toxic metal capture, nanoparticle syntheses, and catalysis. Our low-pressure membrane approach has good reaction and separation selectivities, which are tunable by varying pH, ionic strength, or pressure. The sustainable green chemistry approach under ambient conditions and the evaluation of a reactive poly(acrylic acid) (PAA)-modified polyvinylidene fluoride (PVDF) membrane is described. Two distinct membrane types were obtained through different methods: 1) a stacked membrane through layer-by-layer assembly for the incorporation of enzymes (catalase and glucose oxidase), providing tunable product yields and 2) Fe/Pd nanoparticles for degradation of pollutants, obtained through an in situ green synthesis. Bioreactornanodomain interactions and mixed matrix nanocomposite membranes provide remarkable versatility compared to conventional membranes.

AB Thirty percent of known registered pesticides are chiral and usually exhibit some degree of stereoselectivity in their biodegradation rates and/or toxicity. Since the great majority of chiral pesticides are manufactured and applied as their racemic mixtures, there is a need for defining their stereoselectivity to provide for improved risk assessment and establish, in some cases, the rationale for production of single-or enriched-enantiomer products.

AB Chlordane, a persistent, bioaccumulative and toxic organochlorine pesticide, has been studied for many years. Since the advent of chiral analysis for environmental samples, over 2,400 measurements have been made of various chiral chlordane components. Chlordane enantiomer fractions most often have been reported for air and soil with studies suggesting volatilization from soil is an important source to ambient air, although urban termiticide usage also can influence chiral chlordane measurements. Sediment core studies suggest the small amount of enantioselective degradation of chlordane likely occurs prior to deposition. In general, enantioselective degradation of chlordanes in biota occurs more frequently resulting in more nonracemic values than in other environmental media. There is also more diversity in range and enantiomer preference in biota. Analysis in plants has shown the ability to enantioselectively uptake and transport chlordane compounds from soil to root, from air to leaf and within the plant itself. Observation and measurement of chlordane enantiomers can provide a better understanding of the fate, exposure, toxicity, and risk of chlordanes and other chiral compounds in the environment.

AB The USEPA's ecological risk assessment framework provides a clearly defined process for conducting ecological risk assessments for the registration and re-evaluation of pesticides. The ultimate product of this framework is an ecological risk characterization and assessment, which integrates data on pesticide use, chemistry, and ecotoxicity. Consideration of chiral pesticides in the risk assessment process poses numerous challenges related to the enantioselectivity in environmental fate processes and ecotoxicity. A critical assessment of risk assessment issues for chiral pesticides is discussed in the context of the USEPA risk assessment framework.

AB In this review, we focus on environmental cleanup and provide a background and overview of current practice; research findings; societal issues; potential environment, health, and safety implications; and future directions for nanoremediation. We also discuss nanoscale zero-valent iron in detail. We searched the Web of Science for research studies and accessed recent publicly available reports from the U.S. Environmental Protection Agency and other agencies and organizations that addressed the applications and implications associated with nanoremediation techniques. We also conducted personal interviews with practitioners about specific site remediations. We aggregated information from 45 sites, a representative portion of the total projects under way, to show nanomaterials used, types of pollutants addressed, and organizations responsible for each site. Nanoremediation has the potential not only to reduce the overall costs of cleaning up large-scale contaminated sites but also to reduce cleanup time, eliminate the need for treatment and disposal of contaminated soil, and reduce some contaminant concentrations to near zero -all in situ.

AB Vapor intrusion is a pathway of potential exposure to volatile and semi-volatile contaminants (collectively referred to here as VOCs or vapors) that migrate from the subsurface to the air inside occupied buildings. Soil vapor intrusion to indoor air can occur regardless of whether a building has a basement, slab-on-grade or crawlspace design. As a basis for a mathematical model a conceptual model is needed, which describes the movement of contaminants from the source to the building, vapor migration barriers and receptors. It also provides a framework for interpreting the processes influencing the fate and transport of contaminants as they move from a source to a receptor. The approach for assessing vapor intrusion will vary from site-to-site, but there are certain elements that are appropriate in most cases. In this chapter the relevant processes have been described, like phase partitioning, biodegradation, advection and dilution within the building due to ventilation. Moreover, the presence of NAPLs, available vapor intrusion models, sampling and analysis procedures and subsurface vapor mitigation have been discussed.

AB OBJECTIVE- Understanding the relationship between multivitamin use and diabetes risk is important given the wide use of multivitamin supplements among U.S. adults.
RESEARCH DESIGN AND METHODS- We prospectively examined supplemental use of multivitamins and individual vitamins and minerals assessed in 1995-1996 in relation to self-reported diabetes diagnosed after 2000 among 232,007 participants in the National Institutes of Health American Association of Retired Persons Diet and Health Study. Multivitamin use was assessed by a food-frequency questionnaire at baseline. Odds ratios (ORs) and 95% CIs were calculated by logistic regression models, adjusted for potential confounders. In total, 14,130 cases of diabetes diagnosed after 2000 were included in the analysis.
RESULTS- Frequent use of any multivitamins was not associated with risk of diabetes after adjustment for potential confounders and uses of individual supplements. Compared with nonusers of any multivitamins, the multivariate ORs among users were 1.07 (95% CI 0.94-1.21) for taking vitamins less than once per week, 0.97 (0.88-1.06) for one to three times per week, 0.92 (0.84-1.00) for four to six times per week, and 1.02 (0.98-1.06) for seven or more times per week (P for trend = 0.64). Significantly lower risk of diabetes was associated with the use of vitamin C or calcium supplements. The multivariate ORs comparing daily users with nonusers were 0.91 (0.86-0.97) for vitamin C supplements and 0.85 (0.80-0.90) for calcium supplements. Use of vitamin E or other individual vitamin and mineral supplements were not associated with diabetes risk.
CONCLUSIONS- In this large cohort of U.S. older adults, multivitamin use was not associated with diabetes risk. The findings of lower diabetes risk among frequent users of vitamin C or calcium supplements warrant further evaluations.

AB Wetlands support physical and ecological functions that result in valuable services to society, including removal of reactive nitrogen (Nr) from surface water and groundwater. We compiled published data from wetland studies worldwide to estimate total Nr removal and to evaluate factors that influence removal rates. Over several orders of magnitude in wetland area and Nr loading rates, there is a positive, near-linear relationship between Nr removal and Nr loading. The linear model (null hypothesis) explains the data better than either a model of declining Nr removal efficiency with increasing Nr loading, or a Michaelis-Menten (saturation) model. We estimate that total Nr removal by major classes of wetlands in the contiguous U.S. is approximately 20-21% of the total anthropogenic load of Nr to the region. Worldwide, Nr removal by wetlands is roughly 17% of anthropogenic Nr inputs. Historical loss of 50% of native wetland area suggests an equivalent loss of Nr removal capacity. Expanded protection and large-scale restoration of wetlands should be considered in strategies to re-balance the global nitrogen cycle and mitigate the negative consequences of excess Nr loading.

AB During the 1980s, whole effluent toxicity testing was incorporated into the regulatory control program for municipal and industrial effluents in the USA, as a complement to chemical-specific limitations. While regulating effluent toxicity offered several advantages, it also required the development of means to identify and control sources of toxicity within effluents, which could include toxicants not previously monitored or even known. To meet this need, the US Environmental Protection Agency developed an effects-directed analysis procedure called "toxicity identification evaluation". This involved a suite of physical/chemical manipulations that are applied to aliquots of a toxic effluent sample, and the relative effects of these manipulations on effluent toxicity are used to infer the type of toxicant(s) responsible for toxicity, and to guide their isolation and analytical identification. This chapter provides an overview of these methods and their component phases: I Characterization, II - Identification, and III - Confirmation. Case examples of toxicant identification in effluents from municipal and industrial sources are discussed, along with a broad summary of the types of toxicants identified, and the characteristics of those toxicants that helped guide their assessment.

AB In order to avoid a bias toward highly toxic but poorly bioavailable compounds in the effect-directed analysis (EDA) of soils and sediments, approaches are discussed to consider bioavailability in EDA procedures. In parallel, complimentary approaches for making toxicity identification evaluations (TIEs) more capable of performing high resolution fractionation, toxicant isolation and identification are described. These approaches focus on three processes including bioaccessiblity based on desorption kinetics from the abiotic matrix, activity driven partitioning into pore water and biota tissue or a biomimetic tool, and EDA and TIE in tissues and body fluids representing toxicological bioavailability including the toxicokinetics of the selected organism. Bioaccessibility may be addressed by extraction procedures that are designed to yield rapidly desorbing fractions including mild solvent extraction, desorption into water with subsequent adsorption to a competitive adsorbent such as TENAX (R) or cyclodextrin, supercritical fluid extraction, or biomimetic extraction with gut fluids of potentially affected organisms. While equilibrium partitioning-based extraction procedures may simulate partitioning into biota quite well they often fail to provide sufficient amounts of toxicants for subsequent EDA and TIE. Partition-based dosing, which may be combined with bioaccessibility-directed extraction methods, provides an excellent tool to simulate partitioning in sediments and to provide constant and well-defined concentrations in bioassays. EDA studies in fish and mussel tissues as well as in fish bile demonstrate the potency of the identification of bioavailable toxicants in biota. Continued research on the described approaches promises to improve the usefulness of both EDA and TIE in future applications.

AB Three classes of DNA damage were assessed in human placentas collected (2000-2004) from 51 women living in the Teplice region of the Czech Republic, a mining area considered to have some of the worst environmental pollution in Europe in the 1980s. Polycyclic aromatic hydrocarbon (PAH)-DNA adducts were localized and semiquantified using immunohistochemistry (IHC) and the Automated Cellular Imaging System (ACIS). More generalized DNA damage was measured both by (32)P-postlabeling and by abasic (AB) site analysis. Placenta stained with antiserum elicited against DNA modified with 7 beta,8 alpha-dihydroxy-9 alpha,10 alpha-epoxy-7,8,9,10-tetrahydro-benzo[a]pyrene (BPDE) revealed PAH-DNA adduct localization in nuclei of the cytotrophoblast (CT) cells and syncytiotrophoblast (ST) knots lining the chorionic villi. The highest levels of DNA damage, 49-312 PAH-DNA adducts/10(8) nucleotides, were found by IHC/ACIS in 14 immediately fixed placenta samples. An additional 37 placenta samples were stored frozen before fixation and embedding, and because PAH-DNA adducts were largely undetectable in these samples, freezing was implicated in the loss of IHC signal. The same placentas (n = 37) contained 1.7-8.6 stable/bulky DNA adducts/10(8) nucleotides and 0.6-47.2 AB sites/10(5) nucleotides. For all methods, there was no correlation among types of DNA damage and no difference in extent of DNA damage between smokers and nonsmokers. Therefore, the data show that DNA from placentas obtained in Teplice contained multiple types of DNA damage, which likely arose from various environmental exposures. In addition, PAH-DNA adducts were present at high concentrations in the CT cells and ST knots of the chorionic villi. Environ. Mol. Mutagen. 52:58-68, 2011. (C) 2010 Wiley-Liss, Inc.

AB The United States Environmental Protection Agency/Environmental Response Team (US EPA/ERT), in conjunction with St. John's College, Dr B R Ambedkar University, Agra, India, is conducting a study to determine mercury vapor emission rates resulting from broken compact fluorescent lamps (CFLs) in a residential setting. The overall objectives of the study are to obtain a mercury emission model and provide a homeowner with cleanup procedures and disposal options for broken CFLs. An important component in achieving these objectives is the determination of the total mercury content in CFLs for the selection of bulbs to be used in the emission study. Most of the currently available CFLs in the United States (U.S.) market are manufactured in China for U.S. companies. Several different types of CFLs were purchased from local stores and the cap and electronic parts were removed without breaking the bulb. The bulb was then placed into a 2-L polypropylene bottle containing glass stoppers or glass marbles in a mixture of nitric acid and bromine monochloride solution (BrCl). The mixture was shaken to break the lamp and allow the mercury to be completely absorbed by the BrCl. The digested samples were analyzed for mercury using standard cold vapor atomic absorption (CVAA) methods. This CFL preparation method provides excellent results for laboratory control samples (typically, 90%-110% recovery) and good repeatability for CFL bulb analyses. The sampling and analysis phases of this study are discussed in this paper.

AB BACKGROUND: This commentary evolved from a workshop sponsored by the National Institute of Environmental Health Sciences titled "Superfund Contaminants: The Next Generation" held in Tucson, Arizona, in August 2009. All the authors were workshop participants.
OBJECTIVES: Our aim was to initiate a dynamic, adaptable process for identifying contaminants of emerging concern (CECs) that are likely to be found in future hazardous waste sites, and to identify the gaps in primary research that cause uncertainty in determining future hazardous waste site contaminants.
DISCUSSION: Superfund-relevant CECs can be characterized by specific attributes: They are persistent, bioaccumulative, toxic, occur in large quantities, and have localized accumulation with a likelihood of exposure. Although still under development and incompletely applied, methods to quantify these attributes can assist in winnowing down the list of candidates from the universe of potential CECs. Unfortunately, significant research gaps exist in detection and quantification, environmental fate and transport, health and risk assessment, and site exploration and remediation for CECs. Addressing these gaps is prerequisite to a preventive approach to generating and managing hazardous waste sites.
CONCLUSIONS: A need exists for a carefully considered and orchestrated expansion of programmatic and research efforts to identify, evaluate, and manage CECs of hazardous waste site relevance, including developing an evolving list of priority CECs, intensifying the identification and monitoring of likely sites of present or future accumulation of CECs, and implementing efforts that focus on a holistic approach to prevention.

ID ACROLEIN; EXPOSURE
AB Background: Quantifying the benefits of reducing hazardous air pollutants (HAPs, or air toxics) has been limited by gaps in toxicological data, uncertainties in extrapolating results from high-dose animal experiments to estimate human effects at lower doses, limited ambient and personal exposure monitoring data, and insufficient economic research to support valuation of the health impacts often associated with exposure to individual air toxics.
Objectives: To address some of these issues, the U. S. Environmental Protection Agency held the Workshop on Estimating the Benefits of Reducing Hazardous Air Pollutants (HAPs) in Washington, DC, from 30 April to 1 May 2009.
Discussion: Experts from multiple disciplines discussed how best to move forward on air toxics benefits assessment, with a focus on developing near-term capability to conduct quantitative benefits assessment. Proposed methodologies involved analysis of data-rich pollutants and application of this analysis to other pollutants, using dose-response modeling of animal data for estimating benefits to humans, determining dose-equivalence relationships for different chemicals with similar health effects, and analysis similar to that used for criteria pollutants. Limitations and uncertainties in economic valuation of benefits assessment for HAPS were discussed as well.
Conclusions: These discussions highlighted the complexities in estimating the benefits of reducing air toxics, and participants agreed that alternative methods for benefits assessment of HAPs are needed. Recommendations included clearly defining the key priorities of the Clean Air Act air toxics program to identify the most effective approaches for HAPs benefits analysis, focusing on susceptible and vulnerable populations, and improving dose-response estimation for quantification of benefits.

AB The effects of chemical exposures during pregnancy on children's health have been an increasing focus of environmental health research in recent years, leading to greater interest in biomonitoring of chemicals in women of childbearing age in the general population. Measurements of mercury in blood from the National Health and Nutrition Examination Survey are frequently reported for "women of childbearing age," defined to be of ages 16-49 years. The intent is to represent prenatal chemical exposure, but blood mercury levels increase with age. Furthermore, women of different ages have different probabilities of giving birth. We evaluated options to address potential bias in biomonitoring summary statistics for women of childbearing age by accounting for age-specific probabilities of giving birth. We calculated median and 95th percentile levels of mercury, PCBs, and cotinine using these approaches: option 1: women aged 16-49 years without natality adjustment; option 2: women aged 16-39 years without natality adjustment; option 3: women aged 16-49 years, adjusted for natality by age; option 4: women aged 16-49 years, adjusted for natality by age and race/ethnicity. Among the three chemicals examined, the choice of option has the greatest impact on estimated levels of serum PCBs, which are strongly associated with age. Serum cotinine levels among Black non-Hispanic women of childbearing age are understated when age-specific natality is not considered. For characterizing in utero exposures, adjustment using age-specific natality provides a substantial improvement in estimation of biomonitoring summary statistics. Published by Elsevier Inc.

AB Since the 1970s, several formal biomonitoring programs have been initiated to monitor temporal and spatial trends of persistent, bioaccumulative, and (or) toxic chemicals (PBTs) in the Great Lakes. Researchers have used a variety of approaches to deal with common issues that arise in these programs and there is considerable debate in the literature as to the most appropriate methods to use. Here, we critically review factors of importance in biomonitoring programs and common methods used for dealing with them under three main categories: organism-specific factors (lipid, age, size, sex, growth and bioenergetics, diet, and chemical biotransformation), study design (choice of tissue type, compositing, replication and length of monitoring program, sampling frequency, selection of contaminants to include in monitoring programs, and use of specimen banks for retrospective studies), and data analysis (accounting for changes in analytical methodology, treatment of censored data, assessment of compound classes, comparison of empirical models, mechanistic models, and spatial assessments). We use data from the literature as well as longterm measurements of polychlorinated biphenyls (PCBs) in lake trout (Salvelinus namaycush) collected in Lake Ontario as part of monitoring programs run by Environment Canada, the Ontario Ministry of the Environment, and the United States Environmental Protection Agency to illustrate these factors. We find that, in general, there are several defensible methods, ranging from simple to complex, to deal with the issues considered here, with each having specific advantages and disadvantages. The optimal approach depends largely on the program objectives, particularly if the results are meant for the public (understandable without a scientific background) or for research purposes (balance between complexity versus simplicity). Given that data analysis typically requires fewer resources compared to other aspects of monitoring programs, it may be feasible to use more than one data analysis approach to increase credibility of the results and to improve comparability of data among studies. The importance of conducting preliminary surveys and (or) pilot studies and regular review of ongoing programs (e.g., through a power analysis) is emphasized.

TI Surface Charge-Dependent Toxicity of Silver Nanoparticles
SO ENVIRONMENTAL SCIENCE & TECHNOLOGY

ID GOLD; GENERATION; STRENGTH; CELLS
AB As a result of the extensive number of applications of silver nanoparticles (AgNPs), their potential impacts, once released into the environment, are of concern. The toxicity of AgNPs was reported to be dependent on various factors such as particle size, shape and capping agent Although these factors may play a role in AgNPs toxicity, the results presented herein suggest that surface charge is one of the most important factors that govern the toxicity of AgNPs. In the current study, the toxicity of four AgNPs representing various surface charging scenarios ranging from highly negative to highly positive was investigated. These AgNPs were (1) uncoated H(2)-AgNPs, (2) citrate coated AgNPs (Citrate-AgNPs), (3) polyvinylpyrrolidone coated AgNPs (PVP-AgNPs), and (4) branched polyethyleneimine coated AgNPs (BPEI-AgNPs). Our results clearly demonstrate that the AgNPs exhibited surface charge-dependent toxicity on the bacillus species investigated. Furthermore, ultrafiltration membranes were utilized to purify the AgNPs suspensions from residual impurities prior to the introduction to the microbes. This step was crucial in determining the true AgNPs toxicity and is either missing or not explicitly mentioned in most of the reported toxicity studies.

AB Persistence of Bacillus globigii spores, a surrogate for Bacillus anthracis, was studied on biofouled concrete-lined slides in drinking water using biofilm annular reactors. Reactors were inoculated with B. globigii spores and persistence was monitored in the bulk and biofilm phases, first in dechlorinated water and later with free chlorine concentrations of 1 and 5 mg/L. In the dechlorinated study, a steady state population of spores developed on the slides. The addition of free chlorine at 5 mg/L decreased the adhered spore density by 2-logs within 4 hours and spores were not detected after 67 and 49 hours in the presence of 1 and 5 mg/L free chlorine, respectively. This suggests that adhered spores can persist in non-chlorinated conditions, but detach and/or are inactivated upon addition of free chlorine. When injected into a chlorinated reactor, adhered spore density continually decreased and spores were either undetectable or unquantifiable by 48 hours for both 1 and 5 mg/L chlorine concentrations. Results from these experiments suggest that the presence of a free chlorine residual limits adherence of viable spores to biofouled concrete-lined pipe walls by inactivating spores before they have attached. Both free chlorine concentrations (1 and 5 mg/L) were equally effective at inactivating spores in terms of log reduction, but the higher concentrations yielded faster rates of log reduction.

AB An adverse outcome pathway (AOP) is a sequence of key events from a molecular-level initiating event and an ensuing cascade of steps to an adverse outcome with population level significance To implement a predictive strategy for ecotoxicology the multiscale nature of an AOP requires computational models to link salient processes (e g in chemical uptake toxicokinetics to toxicodynamic and population dynamics) A case study with domoic acid was used to demonstrate strategies and enable generic recommendations for developing computational models in an effort to move toward a toxicity testing paradigm focused on toxicity pathway perturbations applicable to ecological risk assessment Domoic acid an algal toxin with adverse effects on both wildlife and humans is a potent agonise for kainate receptors (ionotropic glutamate receptors whose activation leads to the influx of Na(+) and Ca(2+)) Increased Ca(2+) concentrations result in neuronal excitotoxicity and cell death primarily in the hippocampus which produces seizures impairs learning and memory and alters behavior in some species Altered neuronal Ca(2+) is a key process in domoic acid toxicity which can be evaluated in vitro Furthermore results of these assays would be amenable to mechanistic modeling for identifying domoic acid concentrations and Ca(2+) perturbations that are normal adaptive or clearly toxic In vitro assays with outputs amenable to measurement in exposed populations can link in vitro to in vivo conditions and toxicokinetic information will aid in linking in vitro results to the individual organism Development of an AOP required an iterative process with three important outcomes a critically reviewed stressor specific AOP identification of key processes suitable for evaluation with in vitro assays and strategies for model development Environ Toxicol Chem 2011 30 9-21 (C) 2010 SETAC

AB The toxicological effects of many stressors are mediated through unknown or incompletely characterized mechanisms of action The application of reverse engineering complex interaction networks from high dimensional miles data (gene protein metabolic signaling) can be used to overcome these limitations This approach was used to characterize adverse outcome pathways (AOPs) for chemicals that disrupt the hypothalamus-pituitary gonadal endocrine axis in fathead minnows (FHM Pimephales promelas) Gene expression changes in FHM ovaries in response to seven different chemicals over different times doses and in vivo versus in vitro conditions were captured in a large data set of 868 arrays Potential AOPs of the antiandrogen flutamide were examined using two mutual information based methods to infer gene regulatory networks and potential AOPs Representative networks from these studies were used to predict network paths from stressor to adverse outcome as candidate AOPs The relationship of individual chemicals to an adverse outcome can be determined by following perturbations through the network in response to chemical treatment thus leading to the nodes associated with the adverse outcome Identification of candidate pathways allows for formation of testable hypotheses about key biological processes biomarkers or alternative endpoints that can be used to monitor an AOP Finally the unique challenges facing the application of this approach in ecotoxicology were identified and a road map for the utilization of these tools presented Environ Toxicol Chem 2011,30 22-38 (C) 2010 SETAC

AB Animals have evolved diverse protective mechanisms for responding to toxic chemicals of both natural and anthropogenic origin From a governmental regulatory perspective these protective responses complicate efforts to establish acceptable levels of chemical exposure To explore this issue we considered vertebrate endocrine systems as potential targets for environmental contaminants Using the hypothalamic pituitary thyroid (HPT) hypothalamic pituitary gonad (HPG) and hypothalamic-pituitary-adrenal (HPA) axes as case examples we identified features of these systems that allow them to accommodate and recover from chemical insults In doing so a distinction was made between effects on adults and those on developing organisms This distinction was required because endocrine system disruption in early life stages may alter development of organs and organ systems resulting in permanent changes in phenotypic expression later in life Risk assessments of chemicals that impact highly regulated systems must consider the dynamics of these systems in relation to complex environmental exposures A largely unanswered question is whether successful accommodation to a toxic insult exerts a fitness cost on individual animals resulting in adverse consequences for populations Mechanistically based mathematical models of endocrine systems provide a means for better understanding accommodation and recovery In the short term these models can be used to design experiments and interpret study findings Over the long term a set of validated models could be used to extrapolate limited in vitro and in vivo testing data to a broader range of untested chemicals, species and exposure scenarios With appropriate modification Tier 2 assays developed in support of the U S Environmental Protection Agency s Endocrine Disruptor Screening Program could be used to assess the potential for accommodation and recovery and inform the development of mechanistically based models Environ Toxicol Chem 2011,30 39-51 (C) 2010 SETAC

AB Maintaining the viability of populations of plants and animals is a key focus for environmental regulation Population level responses integrate the cumulative effects of chemical stressors on individuals as those individuals interact with and are affected by their conspecifics, competitors predators, prey habitat and other biotic and abiotic factors Models of population level effects of contaminants can integrate information from lower levels of biological organization and feed that information into higher level community and ecosystem models As individual level endpoints are used to predict population responses this requires that biological responses at lower levels of organization be translated Into a form that is usable by the population modeler In the current study we describe how mechanistic data as captured in adverse outcome pathways (AOPs) can be translated Into modeling focused on population level risk assessments First we describe the regulatory context surrounding population modeling, risk assessment and the emerging role of AOPs Then we present a succinct overview of different approaches to population modeling and discuss the types of data needed for these models We describe how different key biological processes measured at the level of the individual serve as the linkage or bridge between AOPs and predictions of population status including consideration of community level interactions and genetic adaptation Several case examples illustrate the potential for use of AOPs in population modeling and predictive ecotoxicology Finally we make recommendations for focusing toxicity studies to produce the quantitative data needed to define AOPs and to facilitate their incorporation into population modeling Environ Toxicol Chem 2011 30 64-76 (C) 2010 SETAC

AB Objective: To describe the short-term changes in growth of uterine leiomyomas (fibroids).
Design: Prospective observational study.
Setting: University research center.
Patient(s): Premenopausal women with fibroids (18 blacks and 18 whites) recruited through a physician network and community outreach.
Intervention(s): Not applicable.
Main Outcome Measure(s): The volumes of 101 fibroids were measured at enrollment, 3, 6, and 12 months with magnetic resonance imaging, resulting in three interval-specific growth rates. Growth spurts were defined by interval growth rates >= 30% per 3 months and substantially greater than during other intervals of observation. An overall measure of short-term change in fibroid growth was calculated as the variance of the three interval-specific growth rates.
Result(s): Growth spurts were observed in 37 of the 101 fibroids, a prevalence nearly tenfold higher than that attributable to potential measurement error. Fibroids from the same woman did not have similar short-term growth, nor were woman-specific factors (age, race/ethnicity, parity, body mass) or the fibroid position in the uterus important. However, large fibroids (>5 cm diameter) had less short-term change than smaller fibroids.
Conclusion(s): Short spurts of growth are common for fibroids, suggesting that tumor biology may change rapidly. (Fertil Steril(R) 2011;95:242-6. (C) 2011 by American Society for Reproductive Medicine.)

AB A new condensed toluene mechanism is incorporated into the Community Multiscale Air Quality Modeling system. Model simulations are performed using the CB05 chemical mechanism containing the existing (base) and the new toluene mechanism for the western and eastern US for a summer month. With current estimates of tropospheric emission burden, the new toluene mechanism increases monthly mean daily maximum 8-h ozone by 1.0-3.0 ppbv in Los Angeles, Portland, Seattle, Chicago, Cleveland, northeastern US, and Detroit compared to that with the base toluene chemistry. It reduces model mean bias for ozone at elevated observed ozone concentrations. While the new mechanism increases predicted ozone, it does not enhance ozone production efficiency. A sensitivity study suggests that it can further enhance ozone if elevated toluene emissions are present. While it increases in-cloud secondary organic aerosol substantially, its impact on total fine particle mass concentration is small.

TI ESP v1.0: methodology for exploring emission impacts of future scenarios
in the United States
SO GEOSCIENTIFIC MODEL DEVELOPMENT
LA English
DT Article
AB This article presents a methodology for creating anthropogenic emission inventories that can be used to simulate future regional air quality. The Emission Scenario Projection (ESP) methodology focuses on energy production and use, the principal sources of many air pollutants. Emission growth factors for energy system categories are calculated using the MARKAL energy system model. Growth factors for non-energy sectors are based on economic and population projections. These factors are used to grow a 2005 emissions inventory through 2050. The approach is demonstrated for two emission scenarios for the United States. Scenario 1 extends current air regulations through 2050, while Scenario 2 adds a hypothetical CO2 mitigation policy. Although both scenarios show significant reductions in air pollutant emissions through time, these reductions are more pronounced in Scenario 2, where the CO2 policy results in the adoption of technologies with lower emissions of both CO2 and traditional air pollutants. The methodology is expected to play an important role within an integrated modeling framework that supports the US EPA's investigations of linkages among emission drivers, climate and air quality.

AB This paper examines the operational performance of the Community Multiscale Air Quality (CMAQ) model simulations for 2002-2006 using both 36-km and 12-km horizontal grid spacing, with a primary focus on the performance of the CMAQ model in predicting wet deposition of sulfate (SO(4)(=)), ammonium (NH(4)(+)) and nitrate (NO(3)(-)). Performance of the wet deposition estimates from the model is determined by comparing CMAQ predicted concentrations to concentrations measured by the National Acid Deposition Program (NADP), specifically the National Trends Network (NTN). For SO(4)(=) wet deposition, the CMAQ model estimates were generally comparable between the 36-km and 12-km simulations for the eastern US, with the 12-km simulation giving slightly higher estimates of SO(4)(=) wet deposition than the 36-km simulation on average. The result is a slightly larger normalized mean bias (NMB) for the 12-km simulation; however both simulations had annual biases that were less than +/- 15% for each of the five years. The model estimated SO(4)(=) wet deposition values improved when they were adjusted to account for biases in the model estimated precipitation. The CMAQ model underestimates NH(4)(+) wet deposition over the eastern US, with a slightly larger underestimation in the 36-km simulation. The largest underestimations occur in the winter and spring periods, while the summer and fall have slightly smaller underestimations of NH(4)(+) wet deposition. The underestimation in NH(4)(+) wet deposition is likely due in part to the poor temporal and spatial representation of ammonia (NH(3)) emissions, particularly those emissions associated with fertilizer applications and NH(3) bidirectional exchange. The model performance for estimates of NO(3)(-) wet deposition are mixed throughout the year, with the model largely underestimating NO(3)(-) wet deposition in the spring and summer in the eastern US, while the model has a relatively small bias in the fall and winter. Model estimates of NO(3)(-) wet deposition tend to be slightly lower for the 36-km simulation as compared to the 12-km simulation, particularly in the spring. The underestimation of NO(3)(-) wet deposition in the spring and summer is due in part to a lack of lightning generated NO emissions in the upper troposphere, which can be a large source of NO in the spring and summer when lightning activity is the high. CMAQ model simulations that include production of NO from lightning show a significant improvement in the NO(3)(-) wet deposition estimates in the eastern US in the summer. Overall, performance for the 36-km and 12-km CMAQ model simulations is similar for the eastern US, while for the western US the performance of the 36-km simulation is generally not as good as either eastern US simulation, which is not entire unexpected given the complex topography in the western US.

LA English
DT Article; Book Chapter
ID STABILIZATION
AB This chapter aims to provide a succinct integration of the projected warming the earth is likely to experience in the decades ahead, the emission reductions that may be needed to constrain this warming, and the technologies needed to help achieve these emission reductions. Transparent modeling tools and the most recent literature are used, to quantify the challenge posed by climate change and potential technological remedies. The chapter examines forces driving CO2 emissions, how different emission trajectories could affect warming this century, a sector-by-sector summary of mitigation options, and R&D priorities. It is concluded that it is too late too avoid substantial warming; the best result that appears achievable, would be to constrain warming to about 2 degrees C (range of 1.3-2.7 degrees C) above pre-industrial levels by 2100. In order to constrain warming to such a level, the current annual 3% CO2 emission growth rate needs to transform rapidly to an annual decrease rate of from 2% to 3% for decades. Further, the current generation of energy generation and end use technologies are capable of achieving less than half of the emission reduction needed for such a major mitigation program. New technologies will have to be developed and deployed at a rapid rate, especially for the key power generation and transportation sectors. Current energy technology research, development, demonstration and deployment programs fall far short of what is required.

AB Addressing building energy use is the critical first step in any strategic plan for mitigating climate change. Buildings have a direct impact on estimated global climate change due to their large carbon footprint. Energy use in the building sector is the largest man-made contributor to climate change, and coincidentally a key sector to start mitigating climate change. To avoid revisiting problems such as sick building syndrome arising from aggressive building weatherization programs in the 1970s, it is critical that policy makers, regulators, and strategic planners remember that the primary function of buildings is not saving energy. The bottom line of why we build buildings is for safety and comfort in our homes, to enhance productivity in the work-place, and to ensure an optimal learning environment in our schools. The fundamental services of improving human health, comfort, productivity, and performance should not be compromised as we strive to minimize energy use in buildings. A one-dimensional focus on energy could result in unsustainable policies and practices. Much is understood about technologies, materials, and design techniques that can reduce energy use in buildings. However, much attention must be paid to recognizing how these approaches can enhance or damage human health and productivity as well as the environment. The focus of this chapter is not existing energy sectors and conservation technologies that have been extensively understood and considered in the literature, but on underutilized mitigation techniques that both increase the sustainability of our buildings while maintaining a focus on human health and the environment. A key intersection between climate change, buildings, and human health is building materials and products, and an effective testing and information transfer program is urgently needed so that building stakeholders have the information and tools they need to make good decisions during the design, construction, operation, and renovation phases of buildings.

TI Reduction of Multi-pollutant Emissions from Industrial Sectors: The US
Cement Industry - A Case Study
SO GLOBAL CLIMATE CHANGE - THE TECHNOLOGY CHALLENGE
SE Advances in Global Change Research
LA English
DT Article; Book Chapter
AB Carbon dioxide (CO2) accounts for more than 90% of worldwide CO2-eq greenhouse gas (GHG) emissions from industrial sectors other than power generation. Amongst these sectors, the cement industry is one of the larger industrial sources of CO2 emissions. In 2005, this industry accounted for about 6% of the global anthropogenic CO2 emissions. Further, global production of cement has been growing steadily, with the main growth being in Asia. Considering these trends, the worldwide cement industry is a key industrial sector relative to CO2 emissions.
The development of policy options for managing emissions and air quality can be made more effective and efficient through sophisticated analyses of relevant technical and economic factors. Such analyses are greatly enhanced by the use of an appropriate modeling framework. Accordingly, the Industrial Sectors Integrated Solutions (ISIS) model for industrial sectors is under development at the U.S. Environmental Protection Agency (U.S. EPA). Currently, this model is populated with data on the U.S. cement-manufacturing sector and efforts are underway to build representations of the U.S. pulp and paper and iron and steel sectors.
In this chapter, ISIS was used to conduct an example analysis of the U.S. cement sector to gain some insights relative to two broad questions: (1) what range of CO2 reductions may be practicable in the near-term, and (2) for that range, what may be the market characteristics for the U.S. cement industry. These questions are relevant because in the absence of carbon capture and sequestration (CCS) technology, the path forward for reducing CO2 emissions in the near-term (e.g., decade ending 2020) will need to depend on the currently available energy efficiency measures and raw material and product substitution approaches.

AB The purpose of this work is to investigate source functions for multicomponent DNAPLs under heterogeneous conditions using a streamtube approach. Heterogeneity in the hydraulic conductivity field is represented by a collection of streamtubes with a distribution of travel times, and the DNAPL is assumed to be distributed uniformly across all streamtubes. Dissolution from each streamtube is assumed to follow Raoult's law. Results are used to assess how multi-component dissolution alters the source function relative to single component dissolution, as well as assess the relative importance of hydraulic conductivity heterogeneity and multi-component dissolution on the source function. Source functions for both single and multi-component DNAPLs indicate that flushing efficiency decreases as solubility decreases. However, this effect is more pronounced for the less soluble compounds in the multi-component case due to the preferential elution of the more soluble compounds. Source functions for both single and multi-component DNAPLs also indicate that greater flux reduction is achieved through less mass removal as heterogeneity increases, however the effect is less pronounced in the multi-component case.

In this critical review, we present current work towards developing alternative methods for synthesizing a wide range of high-quality nanomaterials with predictable and controllable size, shape, composition, morphology and crystallinity. In particular, we focus on the inherent advantages of utilizing porous membrane templates, ultrasonic and microwave irradiation, alternative solvent systems, as well as biologically-inspired reagents as reasonably cost-effective, environmentally responsible methods to generate metal, metal oxide, fluoride, sulfide, selenide and phosphate nanomaterials.

AB Novel magnetically separable TiO(2)-guanidine-(Ni,Co)Fe(2)O(4) nanomaterials were prepared and characterised by a series of techniques including XRD, SEM, TEM, N(2) physisorption as well as XPS and subsequently tested for their photocatalytic activities in the selective transformation of malic acid in aqueous solution. The modification with guanidine, which remarkably decreases the band gap of the metal oxide, was found to have a significant effect in the photocatalytic activity of the materials under visible light, showing a remarkably superior activity to that of the commercial Degussa P25. These materials are also envisaged to have interesting photocatalytic activities under sunlight.

AB The design of the molecule itself is the earliest phase in the process of developing useful products. Two of the 12 green chemistry principles, which state that chemicals should be designed to have minimal toxicity and degrade environmentally to innocuous products, are central to chemical design. Previously we used a series of case studies to show that generalizations about the effects of molecular structure can be used to design small molecules for biodegradability. Here, we extend one of the case studies (synthetic musk fragrances) to a wider range of structures, and address all three PBT properties (persistence, bioaccumulation, toxicity). To this end, we first summarize ready biodegradation and aquatic toxicity data for musks including unpublished data from US Premanufacture Notice (PMN) chemicals. Bioaccumulation potential is then estimated for this set of musks using EPA's BCFBAFC (c) (a component of EPI Suite (c)), KOAWIN (c) and ECOSAR (c) programs, and the results are used to compare musks across the various structural classes and make inferences about their environmental attributes. Last, the analysis is extended to target molecules. In this way we show how predictive methods and knowledge can be included as additional facets in rational design of small molecules.

AB A survey of enteric viruses and indicator bacteria was carried out in eight community water supply sources (four wells and four springs) in East Tennessee. Seven sites derived their water from carbonate aquifers and one from fractured sandstone. Four of the sites were deemed "low-risk" based on prior monitoring of fecal indicators and factors such as presence of thick layers of overlying sediments. The remaining sites were deemed "high-risk." Enteric viruses (enterovirus and reovirus) were detected by cell culture at least once in seven of the eight wells or springs including all but one of the four low-risk sites. Viral RNA, however, was not detected in any of the samples by reverse transcription-polymerase chain reaction. Conventional indicators of microbial contamination (Escherichia coli and total coliform bacteria) were detected together with culturable viruses in seven of nine virus positive samples. Bacteroides, an alternative fecal indicator which has not previously been used in groundwater investigations, was also detected in all but one of the samples containing E. coli or total coliform bacteria, as well as in one sample where viruses were present in the absence of other bacterial indicators. The study highlights some of the challenges involved in surveys of virus occurrence and indicates that culturable enteric viruses in East Tennessee karst aquifers may be more widespread than previously observed in studies of karst aquifers in Pennsylvania (8%), the Ozark region of Missouri (< 1%), or several other states covered in a national microbial water quality survey conducted by the U.S. Environmental Protection Agency (43%).

AB Reliable quantitative data are lacking that document the prevalence of ingestion of soil and other "non-food" substances among U.S. children and adults. This article explores the proportion of the U.S. population that ingests substances such as soil, clay, starch, paint, or plaster. We compiled data from the National Health and Nutrition Examination Survey (NHANES) collected from years 1971-1975 (NHANES I) and 1976-1980 (NHANES II) because these particular surveys asked participants specific questions about non-food ingestion practices. We examined the prevalence of the behavior across multiple demographic variables, such as age, gender, education, and income level. Approximately 1% (NHANES II) to 2.5% (NHANES I) of the U.S. population ingests some type of non-food substance. The most notable variation across the demographic subgroups studied was the difference in estimated prevalence among young children (1 to <3 years) compared to older children and adults. Estimated prevalence was also higher among blacks compared to whites and within lower compared to higher socioeconomic groups. This analysis helps fill data gaps on the relative pattern of non-food ingestion practices on a national scale. This information provides perspective for risk assessors when evaluating exposure variables and for risk managers when weighing risk management alternatives.

AB There is a growing concern about the effects of chemicals on the developing nervous system. Chemical exposure at critical periods of development can be associated with effects ranging from subtle to pro-found on the structure and/or function of the nervous system. Understanding critical biological molecular targets, which underlie chemical-induced neurotoxicity, will provide a scientific basis for risk assessment. Cell signaling molecules such as protein kinase C (PKC) have been shown to play critical roles in motor activity, development of the nervous system, and in learning and memory. PKC also has been shown to be associated with several neurological disorders including Alzheimer's disease, status epilepticus, and cerebellar ataxia. In the literature, there is abundant information linking PKC to cognitive function, long-term potentiation, or brain structural changes. Here, we show the relationship between changes in PKC (as assayed using radioactive material or by western blots) and the neurotoxic effects caused by environmental chemicals in vitro and in vivo.

AB Cell signaling is a complex process which controls basic cellular activities and coordinates actions to maintain normal cellular homeostasis. Alterations in signaling processes have been associated with neurological diseases, such as Alzheimer's and cerebellar ataxia, as well as cancer, autoimmunitiy, and diabetes. Recent evidence also indicates a role for signaling molecules in the adverse effects associated with the exposure to environmental chemicals. One of these signaling molecules is arachidonic acid (AA). AA is abundant in the membrane phospholipids of the brain, where its release has been shown to be involved in synaptic plasticity processes, such as long-term potentiation. AA release is primarily produced by the activation of phospholipases, most commonly by phospholipase A(2) (PLA(2)). The release of H-3-AA is often used as a measure of PLA(2) activity in cell culture studies. In our laboratory, we have demonstrated the relationship between the stimulation of H-3-AA release by persistent chemicals, such as polychlorinated biphenyls and polybrominated diphenyl ethers, and the associated cytotoxicity following in vitro exposure. Understanding the role of the AA signaling pathway in chemically-induced effects on the nervous system will provide specific mode of action information that can be used in assessing the compound risk.

AB In vitro test methods can provide a rapid approach for the screening of large numbers of chemicals for their potential to produce toxicity. In order to identify potential developmental neurotoxicants, assessment of critical neurodevelopmental processes, such as neuronal differentiation and growth has been proposed. PC12 cells have been widely used to study the neurotrophic factor-induced signaling pathways that control differentiation, and as in vitro models to detect the effect of chemicals on neurite outgrowth. Upon exposure to nerve growth factor (NGF), PC12 cells cease to proliferate, extend multiple neurites, and acquire the properties of sympathetic neurons. Measurement of the number and length of neurites during exposure to NGF provides a quantitative assessment of neuronal differentiation and growth. Differentiation and neurite outgrowth can be measured using simple contrast microscopy in live cells, or using automated imaging systems in cells prepared with immunocytochemistry.

AB Laboratory studies involving intentional and highly controlled exposures to air pollutants among groups of human volunteers provide valuable information related to the potential health effects of pollutants regulated under the US Clean Air Act. These controlled human exposure studies often provide biological plausibility for the associations between air-pollutant concentration and a given health endpoint observed in epidemiologic investigations. In some cases, results from human laboratory studies provide evidence of a relevant health effect at ambient or near-ambient concentrations and thus directly support the selection of air quality standard levels. In the recently completed review of the US National Ambient Air Quality Standards (NAAQS) for sulfur dioxide (SO2), the US Environmental Protection Agency (EPA) concluded that short-term exposures to SO2 are causally associated with an increase in respiratory morbidity. This determination was based in large part on findings from laboratory studies of controlled exposures to SO2 among small groups of asthmatic individuals. The purpose of this review is to concisely present an overview of the evidence from controlled human exposure studies of SO2-induced respiratory health effects following short-term exposures. While the majority of these studies were conducted over 20 years ago, the findings and insights gained from this work continues to play an integral role in evaluating the respiratory effects of ambient exposures to SO2.1 year). Stent thrombosis continued to increase to at least 11 years with BMS and to at least 4.5 years with DES. Stent thrombosis rates with BMS versus DES were similar at 1 year (5.1% and 4.0%, respectively) but increased more with DES after the first year (1.9%/year vs. 0.6%/year, respectively). Landmark analysis (>1 year) found DES had a higher frequency of VLSI (p < 0.001) and reinfarction (p = 0.003). DES was the only significant independent predictor of VLST (hazard ratio: 3.79, 95% confidence interval: 1.64 to 8.79, p = 0.002).
Conclusions VLST after primary PCI for STEN occurs with relatively high frequency to at least 11 years with BMS and to at least 4.5 years with DES. Very late stent thrombosis and reinfarction (>1 year) were more frequent with DES. New strategies are needed to manage this problem.

TI In vitro Production of Clostridium difficile Spores for Use in the
Efficacy Evaluation of Disinfectants: A Precollaborative Investigation
SO JOURNAL OF AOAC INTERNATIONAL
LA English
DT Article
ID DISEASE; EPIDEMIC; SPORULATION; GERMINATION; STRAINS
AB Clostridium difficile is a strict anaerobic spore-forming bacterium, and an increasingly common nosocomial pathogen. The U.S. Environmental Protection Agency (EPA) is responsible for the registration of disinfectants, including products designed to treat environmental surfaces contaminated with spores of C. difficile. Product efficacy data are required for registration; however, there is a lack of methodology for generating high-quality spore suspensions for evaluating product performance. As such, a study was carried out to select a suitable C. difficile strain and to develop a stand-alone method to prepare a spore suspension that meets specific criteria necessary for quantitative testing of disinfectants. The criteria are: (1) a spore titer of >8 log(10)/mL, (2) >= 90% spores to vegetative cells, and (3) resistance of spores (determined by viability) to 2.5 M hydrochloric acid (HCl). Several strains of C. difficile (toxigenic and nontoxigenic) were grown on various media (solid and liquid) for varying lengths of time to determine the best combination of incubation conditions and media to optimize spore production and quality. Once the spore production procedure was optimized, a toxigenic strain of C. difficile [American Type Culture Collection (ATCC) 43598] was selected for use in trials to verify repeatability from one production run to the next. The spore suspension was initiated by spreading vegetative cells of C. difficile (ATCC 43598) on CDC anaerobic 5% sheep blood agar plates and incubating for 7-10 days at 36 +/- 1 degrees C under anaerobic conditions. Spores were harvested when >= 90% of the cells converted to spores as determined by observation using phase-contrast microscopy. The spores were washed three times with saline-Tween-80, resuspended in cold deionized water, heated to 70 degrees C for 10 min, evaluated microscopically for quality, and enumerated on cycloserine-cefoxitin-fructose agar containing horse blood and taurocholate. The spore suspension was used to inoculate brushed stainless steel carriers (1 cm in diameter) with and without a soil load in accordance with the Standard Quantitative Carrier Disk Test Method (ASTM E-2197-02) to determine carrier load. Once it was determined that >6 log(10) spores/carrier could be recovered, spores were evaluated for resistance to HCl. The sporulation method presented in this report is simple and repeatable and results in spore suspension of high titer (>8 log(10)/mL) and quality (>= 90%) spores to vegetative cells) that met acid resistance criteria (spores were resistant to 2.5 M HCl for 10 min). In addition, recovery from brushed stainless steel carriers with and without soil load was >6 log(10) spores/carrier. A 6 log(10) performance standard was set forth in the EPA's interim guidance for generating data to support a label claim for effectiveness against C. difficile spores on hard, nonporous surfaces. This precollaborative investigation successfully demonstrated the use of a methodology for in vitro production of C. difficile spores (ATCC 43598) necessary for conducting efficacy tests. A proposal will be submitted to the AOAC INTERNATIONAL Methods Committee on Antimicrobial Efficacy Testing for a collaborative study; see Appendix.

AB Physiologically based pharmacokinetic (PBPK) modeling has reached considerable sophistication in its application to pharmacological and environmental health problems. Yet, mature methodologies for making statistical inferences have not been routinely incorporated in these applications except in a few data-rich cases. This paper demonstrates how improved statistical inference on estimated model parameters from both frequentist and Bayesian points of view can be routinely carried out. We work with a previously developed PBPK model for the formation and disposition of DNA-protein cross-links formed by inhaled formaldehyde in the nasal lining of rats and rhesus monkeys. We purposefully choose this model because it is based on sparse time-course data.

AB This study examines the value of fallow ecosystem services in shifting cultivation, including hydrological externalities that may affect other farms. Using farm-level survey data from the Brazilian Amazon, I estimate a production function to assess the value of forest fallow and test whether it provides local externalities to agricultural production. Soil quality controls, instrumental variables, and spatial econometric approaches help address endogeneity issues. I use GIS data on external forest cover at the farm level and model the hydrological externality as an upstream-to-downstream process. The estimated parameters indicate that fallow contributes significantly to productivity both on farm and downstream. In addition, most farms allocate sufficient land to fallow, accounting for both the value of hydrological spillovers and the opportunity cost of land left out of cultivation. These results suggest that farming communities may have some self-interest in preserving forest cover locally-a finding that may bolster policy efforts aimed at conserving tropical forests for their global public goods.

AB In 106 community-dwelling middle-aged non-smokers we examined the time-course and the acute effects of fine particles (PM2.5) on heart rate variability (HRV), which measures cardiac autonomic modulation (CAM). Twenty-four hours beat-to-beat ECG data were visually examined. Artifacts and arrhythmic beats were removed. Normal beat-to-beat RR data were used to calculate HRV indices. Personal PM2.5 nephelometry was used to estimate 24-h individual-level real-time PM2.5 exposures. We use linear mixed-effects models to assess autocorrelation- and other major confounder-adjusted regression coefficients between 1-6 h moving averages of PM2.5 and HRV indices. The increases in preceding 1-6 h moving averages of PM2.5 was significantly associated with lower HF, LF, and SDNN, with the largest effect size at 4-6 h moving averages and smallest effects size at 1 h moving average. For example, a 10 mu g/m(3) increase in 1 and 6-h moving averages was associated with 0.027 and 0.068 ms(2) decrease in log-HF, respectively, and with 0.024 and 0.071 ms(2) decrease in log-LF, respectively, and with 0.81 and 1.75 ms decrease in SDNN, respectively (all P-values <0.05). PM2.5 exposures are associated with immediate impairment of CAM. With a time-course of within 6 h after elevated PM2.5 exposure, with the largest effects around 4-6 h.

AB Studies have linked increased levels of particulate air pollution to decreased autonomic control, as measured by heart rate variability (HRV), particularly in susceptible populations such as the elderly. In this study, we use data obtained from the 1998 USEPA epidemiology-exposure longitudinal panel study of elderly adults in a Baltimore retirement home to examine the relationship between HRV and PM(2.5) personal exposure. We consider PM(2.5) personal exposure in the aggregate and personal exposure to the components of PM(2.5) as estimated in two ways using receptor models. We develop a Bayesian hierarchical model for HRV as a function of personal exposure to PM(2.5), which integrates HRV measurements and data obtained from personal, indoor and outdoor PM(2.5) monitoring and meteorological data. We found a strong relationship between decreased HRV (HF, LF, r-MSSD and SDNN) and total personal exposure to PM(2.5) at a lag of 1 day. Using personal exposure monitoring (PEM) apportionment results, we examined the relative importance of ambient and non-ambient personal PM(2.5) exposure to HRV and found the effect of internal non-ambient sources of PM(2.5) on HRV to be minimal. Using the PEM apportionment data, a consistent effect of soil at short time scales (lag 0) was found across all five HRV measures, and an effect of sulfate on HRV was seen for HF and r-MSSD at the moving average of lags 0 and 1 days. Modeling of ambient site apportionment data indicated effects of nitrate on HRV at lags of 1 day, and moving averages of days 0 and 1 and days 0-2 for all but the ratio LF/HF. Sulfate had an effect on HRV at a lag of 1 day for four HRV measures (HF, LF, r-MSSD, SDNN) and for LF/HF at a moving average of days 0-2.

AB This paper describes an evaluation of the US Bureau of Labor Statistics' American Time Use Survey (ATUS) for potential use in modeling human exposures to environmental pollutants. The ATUS is a large, on-going, cross-sectional survey of where Americans spend time and what activities they undertake in those locations. The data are reported as a series of sequential activities over a 24-h time period-a "diary day"-starting at 0400 hours. Between 12,000 and 13,000 surveys are obtained each year and the Bureau has plans to continue ATUS for the foreseeable future. The ATUS already has about 73,000 diary days of data, more than twice as many as that which currently exists in the US Environmental Protection Agency's (EPA) "Consolidated Human Activity Database" (CHAD) that the Agency uses for exposure modeling purposes. There are limitations for using ATUS in modeling human exposures to environmental pollutants. The ATUS does not report the location for a number of activities regarded as "personal." For 2006, personal activities with missing location information totaled 572 min/day, on average, for survey participants: about 40% of their day. Another limitation is that ATUS does not distinguish between indoor and outdoor activities at home, two of the traditional locational demarcations used in human exposure modeling. This lack of information affects exposure estimates to both indoor and outdoor air pollutants and potentially affects non-dietary ingestion estimates for children, which can vary widely depending on whether or not a child is indoors. Finally, a detailed analysis of the work travel activity in a subsample from ATUS 2006 indicates that the coding scheme is not fully consistent with a CHAD-based exposure modeling approach. For ATUS respondents in this subsample who reported work as an activity, roughly 48% of their days were missing work travel at one or both ends of the work shift or reported within work-shift travel inconsistently. An extensive effort would be needed to recode work travel data from ATUS for EPA's exposure modeling purposes.

AB The biological effects of acute particulate air pollution exposure in host innate immunity remain obscure and have relied largely on in vitro models. We hypothesized that single acute exposure to ambient or engineered particulate matter (PM) in the absence of other secondary stimuli would activate lung dendritic cells (DC) in vivo and provide information on the early immunological events of PM exposure and DC activation in a mouse model naive to prior PM exposure. Activation of purified lung DC was studied following oropharyngeal instillation of ambient particulate matter (APM). We compared the effects of APM exposure with that of diesel-enriched PM (DEP), carbon black particles (CBP) and silver nanoparticles (AgP). We found that PM species induced variable cellular infiltration in the lungs and only APM exposure induced eosinophilic infiltration. Both APM and DEP activated pulmonary DC and promoted a Th2-type cytokine response from naive CD4+T cells ex vivo. Cultures of primary peribronchial lymph node cells from mice exposed to APM and DEP also displayed a Th2-type immune response ex vivo. We conclude that exposure of the lower airway to various PM species induces differential immunological responses and immunomodulation of DC subsets. Environmental APM and DEP activated DC in vivo and provoked a Th2 response ex vivo. By contrast, CBP and AgP induced altered lung tissue barrier integrity but failed to stimulate CD4+T cells as effectively. Our work suggests that respirable pollutants activate the innate immune response with enhanced DC activation, pulmonary inflammation and Th2-immune responsiveness. Copyright (c) 2010 S.

AB Nanotechnology presents the possibility of revolutionizing many aspects of our lives. People in many settings (academic, small and large industrial, and the general public in industrialized nations) are either developing or using engineered nanomaterials (ENMs) or ENM-containing products. However, our understanding of the occupational, health and safety aspects of ENMs is still in its formative stage. A survey of the literature indicates the available information is incomplete, many of the early findings have not been independently verified, and some may have been over-interpreted. This review describes ENMs briefly, their application, the ENM workforce, the major routes of human exposure, some examples of uptake and adverse effects, what little has been reported on occupational exposure assessment, and approaches to minimize exposure and health hazards. These latter approaches include engineering controls such as fume hoods and personal protective equipment. Results showing the effectiveness - or lack thereof - of some of these controls are also included. This review is presented in the context of the Risk Assessment/Risk Management framework, as a paradigm to systematically work through issues regarding human health hazards of ENMs. Examples are discussed of current knowledge of nanoscale materials for each component of the Risk Assessment/Risk Management framework. Given the notable lack of information, current recommendations to minimize exposure and hazards are largely based on common sense, knowledge by analogy to ultrafine material toxicity, and general health and safety recommendations. This review may serve as an overview for health and safety personnel, management, and ENM workers to establish and maintain a safe work environment. Small start-up companies and research institutions with limited personnel or expertise in nanotechnology health and safety issues may find this review particularly useful.

AB Pyrethroid insecticides bind to voltage-gated sodium channels (VGSCs) and modify their gating kinetics, thereby disrupting neuronal function. Pyrethroids have also been reported to alter the function of other channel types, including activation of voltage-gated calcium channels. Therefore, the present study compared the ability of 11 structurally diverse pyrethroids to evoke Ca2+ influx in primary cultures of mouse neocortical neurons. Nine pyrethroids (tefluthrin, deltamethrin, lambda-cyhalothrin, beta-cyfluthrin, esfenvalerate, S-bioallethrin, fenpropathrin, cypermethrin, and bifenthrin) produced concentration-dependent elevations in intracellular calcium concentration ([Ca2+](i)) in neocortical neurons. Permethrin and resmethrin were without effect on [Ca2+](i). These pyrethroids displayed a range of efficacies on Ca2+ influx; however, the EC50 values for active pyrethroids all were within one order of magnitude. Tetrodotoxin blocked increases in [Ca2+](i) caused by all nine active pyrethroids, indicating that the effects depended on VGSC activation. The pathways for deltamethrin-and tefluthrin-induced Ca2+ influx include N-methyl-D-aspartic acid receptors, L-type Ca2+ channels, and reverse mode of operation of the Na+/Ca2+ exchanger inasmuch as antagonists of these sites blocked deltamethrin-induced Ca2+ influx. These data demonstrate that pyrethroids stimulate Ca2+ entry into neurons subsequent to their actions on VGSCs.

AB Coarse, fine, and ultrafine particulate matter (PM) fractions possess different physical properties and chemical compositions and may produce different adverse health effects. Studies were undertaken to determine whether or not gene expression patterns may be used to discriminate among the three size fractions. Airway epithelial cells obtained from 6 normal individuals were exposed to Chapel Hill coarse, fine or ultrafine PM (250 mu g/ml) for 6 and 24 h (n = 3 different individuals each). RNA was isolated and hybridized to Affymetrix cDNA microarrays. Significant genes were identified and mapped to canonical pathways. Expression of selected genes was confirmed by reverse-transcription polymerase chain reaction (RT-PCR). The numbers of genes altered by coarse, fine, and ultrafine PM increased from 0, 6, and 17 at 6 h to 1281, 302, and 455 at 24 h, respectively. The NRF2-mediated oxidative stress response, cell cycle:G2/M DNA damage checkpoint regulation, and mitotic roles of polo-like kinase were the top three pathways altered by all three fractions. Fine and ultrafine PM displayed more similar gene expression patterns. One example was the increased expression of metallothionein isoforms, reflecting the higher zinc content associated with fine and ultrafine fractions. A set of 10 genes was identified that could discriminate fine and ultrafine PM from coarse PM. These results indicate that common properties shared by the three size fractions as well as size-specific factors, e. g., compositions, may determine the effects on gene expression. Genomic markers may be used to discriminate coarse from fine and ultrafine PM.

AB Inhalation exposure to particulates such as cigarette smoke and coal dust is known to contribute to the development of chronic lung disease. The purpose of this study was to estimate the amount of elemental carbon (EC) deposits from autopsied lung samples from cigarette smokers, miners, and control subjects and explore the relationship between EC level, exposure history, and the extent of chronic lung disease. The samples comprised three subgroups representing never smokers (8), chronic cigarette smokers (26), and coal miners (6). Following the dissolution of lung tissue, the extracted EC residue was quantified using a thermal-optical transmission (TOT) carbon analyzer. Mean EC levels in the lungs of the control group were 56.68 +/- 24.86 (SD) g/g dry lung weight. Respective mean EC values in lung samples from the smokers and coal miners were 449.56 +/- 320.3 g/g and 6678.2 +/- 6162 g/g. These values were significantly higher than those obtained from the never-smoker group. EC levels in the lung and pack-years of cigarette smoking correlated significantly, as did EC levels and the severity of small airway disease. This study provides one of the first quantitative assessments of EC in human lungs from populations at high relative risk for the development of chronic lung disease.

AB Stainless steel welding produces fumes that contain carcinogenic metals. Therefore, welders may be at risk for the development of lung cancer, but animal data are inadequate in this regard. Our main objective was to examine lung tumor production and histopathological alterations in lung-tumor-susceptible (A/J) and -resistant C57BL/6J (B6) mice exposed to manual metal arc-stainless steel (MMA-SS) welding fume. Male mice were exposed to vehicle or MMA-SS welding fume (20 mg/kg) by pharyngeal aspiration once per month for 4 mo. At 78 wk postexposure, gross tumor counts and histopathological changes were assessed and metal analysis was done on extrapulmonary tissue (aorta, heart, kidney, and liver). At 78 wk postexposure, gross lung tumor multiplicity and incidence were unremarkable in mice exposed to MMA-SS welding fume. Histopathology revealed that only the exposed A/J mice contained minimal amounts of MMA-SS welding fume in the lung and statistically increased lymphoid infiltrates and alveolar macrophages. A significant increase in tumor multiplicity in the A/J strain was observed at 78 wk. Metal analysis of extrapulmonary tissue showed that only the MMA-SS-exposed A/J mice had elevated levels of Cr, Cu, Mn, and Zn in kidney and Cr in liver. In conclusion, this study further supports that MMA-SS welding fume does not produce a significant tumorigenic response in an animal model, but may induce a chronic lung immune response. In addition, long-term extrapulmonary tissue alterations in metals in the susceptible A/J mouse suggest that the adverse effects of this fume might be cumulative.

AB Increased incidences of asbestosis have been reported in workers from Libby, MT, associated with exposures to amphibole-contaminated vermiculite. In this study pulmonary and histopathological changes were investigated following Libby amphibole (LA) exposure in a rat model. Rat respirable fractions of LA and amosite (aerodynamic diameter <2.5 mu m) were prepared by water elutriation. Male F344 rats were exposed to single doses of either saline (SAL), amosite (0.65 mg/rat), or LA (0.65 or 6.5 mg/rat) by intratracheal instillation. At times from 1 d to 3 mo after exposure, bronchoalveolar lavage (BAL) was performed and right and left lungs were removed for reverse-transcription polymerase chain reaction (RT-PCR) and histopathological analysis, respectively. Data indicated that 0.65 mg amosite resulted in a higher degree of pulmonary injury, inflammation, and fibrotic events than LA at the same mass dose. Exposure to either amosite or high dose LA resulted in higher levels of cellular permeability and injury, inflammatory enzymes, and iron binding proteins in both BAL fluid and lung tissue at most time points when compared to SAL controls. However, mRNA expression for some growth factors (e. g., platelet-derived growth factor [PDGF]-A and transforming growth factor [TGF]-1 beta), which contribute to fibrosis, were downregulated at several time points. Furthermore, histopathological examination showed notable thickening of interstitial areas surrounding the alveolar ducts and terminal bronchioles. On a mass dose basis, amosite produced a greater acute and persistent lung injury for at least 3 mo after exposure. However, further testing and analysis of LA are needed with regard to the dose metric to fully evaluate its potential fibrogenicity and carcinogenicity.

AB Much of our understanding regarding the mechanisms for induction of disease following inhalation of respirable elongated mineral particles (REMP) is based on studies involving the biological effects of asbestos fibers. The factors governing the disease potential of an exposure include duration and frequency of exposures; tissue-specific dose over time; impacts on dose persistence from in vivo REMP dissolution, comminution, and clearance; individual susceptibility; and the mineral type and surface characteristics. The mechanisms associated with asbestos particle toxicity involve two facets for each particle's contribution: (1) the physical features of the inhaled REMP, which include width, length, aspect ratio, and effective surface area available for cell contact; and (2) the surface chemical composition and reactivity of the individual fiber/elongated particle. Studies in cell-free systems and with cultured cells suggest an important way in which REMP from asbestos damage cellular molecules or influence cellular processes. This may involve an unfortunate combination of the ability of REMP to chemically generate potentially damaging reactive oxygen species, through surface iron, and the interaction of the unique surfaces with cell membranes to trigger membrane receptor activation. Together these events appear to lead to a cascade of cellular events, including the production of damaging reactive nitrogen species, which may contribute to the disease process. Thus, there is a need to be more cognizant of the potential impact that the total surface area of REMP contributes to the generation of events resulting in pathological changes in biological systems. The information presented has applicability to inhaled dusts, in general, and specifically to respirable elongated mineral particles.

AB Properly designing contamination warning systems requires an understanding of potential public health impacts for a range of contaminated water systems and a wide range of contaminants. To address this need, we determined potential impacts for 12 actual systems serving populations ranging from similar to 10(4) to over 10(6) persons by simulating contamination events for the systems. We found several consistent patterns in the estimated impacts (defined as the size of the population receiving an ingestion dose above a given level). Significant impacts, those similar to worst-case impacts, result from injections of contaminants at only a minority of nodes. For contaminants with high thresholds for adverse effects, significant exposures are concentrated near the injection location, and impacts are not sensitive to population served. However, for contaminants with low thresholds, significant exposures are present over a significant fraction of the system, and impacts are sensitive to population. When exposures are concentrated near the injection node, the area affected tends to decrease with increasing population density. Accounting for all possible exposures and events may complicate the design of contamination warning systems.

AB Theory and practical experiences suggest that higher copper levels in drinking water tap samples are typically associated with newer plumbing systems, and levels decrease with increasing plumbing age. Past researchers have developed a conceptual model to explain the 'aging effect' founded in the proposed evolution of copper(II) corrosion by-products on the pipe surface, based on theoretical considerations, anecdotal evidence and some data. In this study, the impact of plumbing age on copper levels in tap water samples and the internal surface corrosion of copper plumbing were systematically evaluated in 16 buildings with plumbing ages ranging from less than one to 44 years, using solids analysis approaches including XPS and XRD. Copper levels decreased with plumbing age and supported theory. A mix of stable and relatively unstable scales appeared on pipes, including cupric hydroxide, cuprite and malachite, although no obvious trend in scale composition with age was noted.

AB Aims:
To determine the range of free available chlorine (FAC) required for disinfection of the live vaccine strain (LVS) and wild-type strains of Francisella tularensis.
Methods and Results:
Seven strains of planktonic F. tularensis were exposed to 0 center dot 5 mg center dot l-1 FAC for two pH values, 7 and 8, at 5 and 25 degrees C. LVS was inactivated 2 to 4 times more quickly than any of the wild-type F. tularensis strains at pH 8 and 5 degrees C.
Conclusions:
Free available chlorine residual concentrations routinely maintained in drinking water distribution systems would require up to two hours to reduce all F. tularensis strains by 4 log(10). LVS was inactivated most quickly of the tested strains.
Significance and Impact of the Study:
This work provides contact time (CT) values that are useful for drinking water risk assessment and also suggests that LVS may not be a good surrogate in disinfection studies.

AB Thalassia testudinum belowground biomass weights, leaf weights, leaf growth rates, areal shoot densities (m-2), and leaf C:N:P ratios were compared to a set of biogeochemical parameters to gain information on seagrass-sediment interactions that may influence seagrass growth. Data were compiled from three surveys conducted in Santa Rosa Sound, located in northwest Florida, at three different meadows in sequential years. Biomass measurements and leaf growth rates decreased between stations along transects from shallow to deeper water. Belowground biomass weights decreased and leaf C:P ratios increased with temperature reflecting a seasonal growth pattern. The T. testudinum parameters were highly correlated with each other. Sulfate reduction rates (at times exceeding 1000 nmol ml-1 day-1) were among the highest recorded for seagrass beds with temperature accounting for 79% of the variation. Even though sulfate reduction rates were high, total Fe:reduced S ratios indicated sufficient Fe to account for all reduced S as pyrite. Sediment Fe, C, N, and organic P concentrations increased with sediment depth, whereas inorganic P decreased with depth, suggesting burial of organic P and root uptake of inorganic P. Leaf C:N:P ratios indicated P-limited growth for two surveys. NH4 + was detected in water above the sediment surface during some surveys demonstrating T. testudinum meadows at times may serve as sources of inorganic N to the water column. Plant parameters correlated with concentrations of sediment organic C and N, Fe, S, and porewater NH4 +. These results highlight the importance of the organic matter and Fe contents of sediments to seagrass growth.

AB This study investigated the influence of the spatial arrangement of habitat patches on the diet and nutrition of a common reef-associated generalist consumer, the western rock lobster Panulirus cygnus. Stable isotopes (C-13/C-12 and N-15/N-14) and gut contents were used to assess diet and nutrition of lobsters collected from 8 shallow patch-reef sites on the lower west coast of Australia in April and October 2005. A distance-based linear model indicated that the predominant benthic habitat surrounding a reef (seagrass or macroalgae/sand-dominated) was an important source of variation in diet and nutrition, explaining significant (p < 0.01) variation in isotope signatures and gut contents of 52.7 and 7.0%, respectively. Mobile invertebrates, sessile filter feeders, coralline algae and seagrass were consumed by lobsters from all sites, but sessile filter feeders (sponges and colonial ascidians) were consumed in significantly greater volumes (p < 0.05) at macroalgae/sand-dominated sites (21.16 +/- 3.0%) than at seagrass-dominated sites (<= 6.1 +/- 1.08%). A modified mass balance mixing model (IsoSource), which factored in C:N ratios of food sources and lobster-specific delta C-13 and delta N-15 discrimination values, was used to determine the contribution of food sources to lobster nutrition. Articulated coralline red algae were an important source, especially from sites dominated by macroalgae and sand contributing 22-72% to nutrition. Bait potentially contributes up to similar to 30% of lobster muscle nutrition and therefore may also play an important nutritional role for lobsters in areas where lobster potting occurs. Macroalgae, rather than seagrass, appears the most likely autochthonous energy source driving P. cygnus production in shallow coastal waters; however, seagrass plays an important role as habitat for lobster prey.

ID OCEAN ACIDIFICATION; AMERICAMYSIS-BAHIA; TOXICITY; DYNAMICS
AB Effects of anthropogenic stressors on animal populations are often evaluated by assembling vital rate responses from isolated cohort studies into a single demographic model. However, these models are difficult to translate into ecological predictions because stressor effects observed in isolated cohorts may differ from those occurring in populations with overlapping generations. This problem is evident in many areas of stressor-response research, including the burgeoning work on ocean acidification. To address this problem, we compared vital rates in experimental cohorts and populations of the mysid Americamysis bahia at 4 levels of resource limitation. This required development of a novel observational scheme that allows inverse estimation of stage-specific vital rates in mixed-age populations without the use of cohort isolation or marking. Using digitally imaged time series observations of stage abundances, the most strongly supported inverse models indicated opposing (i.e. compensatory) effects of resource limitation on adult survival and juvenile maturation. The model with adult survival response only (i.e. no compensation) was also strongly supported. This contrasts with cohort results, where feeding effects on fecundity were strongest. These results suggest that emphasis in stressor-response studies on early life stages and cohorts of uniformly aged individuals may miss important demographic responses and should be augmented by observations of intact populations, especially as methods such as ours become more available.

AB Diseases are increasing in marine ecosystems, and these increases have been attributed to a number of environmental factors including climate change, pollution, and overfishing. However, many studies pool disease prevalence into taxonomic groups, disregarding host-species composition when comparing sites or assessing environmental impacts on patterns of disease presence. We used simulated data under a known environmental effect to assess the ability of standard statistical methods (binomial and linear regression, ANOVA) to detect a significant environmental effect on pooled disease prevalence with varying species abundance distributions and relative susceptibilities to disease. When one species was more susceptible to a disease and both species only partially overlapped in their distributions, models tended to produce a greater number of false positives (Type I error). Differences in disease risk between regions or along an environmental gradient tended to be underestimated, or, even in the wrong direction, when highly susceptible taxa had reduced abundances in impacted sites, a situation likely to be common in nature. Including relative abundance as an additional variable in regressions improved model accuracy, but tended to be conservative, producing more false negatives (Type II error) when species abundance was strongly correlated with the environmental effect. An analysis of field data on bleaching from the Florida Keys, FL, USA, affirmed general results of model simulations. Investigators should be cautious of underlying assumptions about species similarity in susceptibility and species composition when interpreting pooled data on disease risk.

AB Metabolites produced by an organism can be quite extensive, and one analytical technique alone is not capable of their comprehensive detection and identification. The majority of environmental metabolomic studies have implemented proton nuclear magnetic resonance (H-1-NMR) spectroscopy with little attention given to mass spectrometry (MS) techniques. In this chapter, an analytical technique is outlined that incorporates two-dimensional gas chromatography time-of-flight MS (GC x GC-TOF-MS) for the identification and quantification of polar metabolites.

AB Genetic polymorphisms are increasingly recognized as sources of variability not only in toxicokinetic but also in toxicodynamic response to environmental agents. XRCC1 is involved in base excision repair (BER) of DNA; it has variant genotypes that are associated with modified repair function. This analysis focuses on four polymorphisms: three in the coding region that affect protein structure and one in an upstream regulatory sequence that affects gene expression. The Arg399Gln variant is the most widely studied with evidence supporting a quantitative effect of genotype on phenotype. The homozygous variant (Gln/Gln) can have 3-4-fold diminished capacity to remove DNA adducts and oxidized DNA damage. This variant is relatively common in Caucasians and Asians where approximately 10% are homozygous variant. In contrast, the Arg194Trp variant appears to protect against genotoxic effects although the degree to which DNA repair is enhanced by this polymorphism is uncertain. The homozygous variant is rare in Caucasians and African Americans but it is present at 7% in Asians. A third coding region polymorphism at codon 280 appears to decrease repair function but additional quantitative information is needed and the homozygous variant is rare across populations studied. A polymorphism in an upstream promoter binding sequence (-77T > C) appears to lower XRCC1 levels by decreasing gene expression. Based upon genotype effect on phenotype and allele frequency, the current analysis finds that the codon 399 and upstream (-77) polymorphisms have the greatest potential to affect the toxicodynamic response to DNA damaging agents. However, the implications for risk assessment are limited by the likelihood that polymorphisms in multiple BER genes interact to modulate DNA repair. (C) 2011 Elsevier B.V. All rights reserved.

AB 1,2-Dichloroethane (EDC, CAS#107-06-2) is a high production volume halogenated aliphatic hydrocarbon that is used mainly in the manufacture of vinyl chloride. EDC has been found in ambient and residential air samples, as well as in groundwater, surface water and drinking water. EDC has been well-studied in a variety of genotoxicity assays, and appears to involve the metabolic activation of the parent compound. We critically evaluated the genotoxicity data of EDC and its metabolites as part of an evaluation of carcinogenic mechanisms of action of EDC. EDC is genotoxic in multiple test systems via multiple routes of exposure. EDC has been shown to induce DNA adduct formation, gene mutations and chromosomal aberrations in the presence of key activation enzymes (including CYP4505 and/or GSTs) in laboratory animal and in vitro studies. EDC was negative for clastogenesis as measured by the micronucleus assay in mice. In general, an increased level of DNA damage is observed related to the GSH-dependent bioactivation of EDC. Increased chromosomal aberrations with increased CYP450 expression were suggestive of a role for the oxidative metabolites of EDC in inducing chromosomal damage. Taken together, these studies demonstrate that EDC exposure, in the presence of key enzymes (including CYP4505 and/or GSTs), leads to DNA adduct formation, gene mutations and chromosomal aberrations.

AB Strategies to reduce arsenic (As) in rice grain, below concentrations that represent a serious human health concern, require that the mechanisms of As accumulation within grain be established. Therefore, retranslocation of As species from flag leaves into filling rice grain was investigated.
Arsenic species were delivered through cut flag leaves during grain fill. Spatial unloading within grains was investigated using synchrotron X-ray fluorescence (SXRF) microtomography. Additionally, the effect of germanic acid (a silicic acid analog) on grain As accumulation in arsenite-treated panicles was examined.
Dimethylarsinic acid (DMA) and monomethylarsonic acid (MMA) were extremely efficiently retranslocated from flag leaves to rice grain; arsenate was poorly retranslocated, and was rapidly reduced to arsenite within flag leaves; arsenite displayed no retranslocation. Within grains, DMA rapidly dispersed while MMA and inorganic As remained close to the entry point. Germanic acid addition did not affect grain As in arsenite-treated panicles. Three-dimensional SXRF microtomography gave further information on arsenite localization in the ovular vascular trace (OVT) of rice grains.
These results demonstrate that inorganic As is poorly remobilized, while organic species are readily remobilized, from leaves to grain. Stem translocation of inorganic As may not rely solely on silicic acid transporters.

AB Transgenic plants can offer agricultural benefits, but the escape of transgenes is an environmental concern. In this study we tested the hypothesis that glyphosate drift and herbivory selective pressures can change the rate of transgene flow between the crop Brassica napus (canola), and weedy species and contribute to the potential for increased transgene escape risk and persistence outside of cultivation.
We constructed plant communities containing single transgenic B. napus genotypes expressing glyphosate herbicide resistance (CP4 EPSPS), lepidopteran insect resistance (Cry1Ac), or both traits ('stacked'), plus nontransgenic B. napus, Brassica rapa and Brassica nigra. Two different selective pressures, a sublethal glyphosate dose and lepidopteran herbivores (Plutella xylostella), were applied and rates of transgene flow and transgenic seed production were measured.
Selective treatments differed in the degree in which they affected gene flow and production of transgenic hybrid seed. Most notably, glyphosate-drift increased the incidence of transgenic seeds on nontransgenic B. napus by altering flowering phenology and reproductive function.
The findings of this study indicate that transgenic traits may be transmitted to wild populations and may increase in frequency in weedy populations through the direct and indirect effects of selection pressures on gene flow.

AB P>Carbon sequestration has focused renewed interest in understanding how forest management affects forest carbon gain over timescales of decades, and yet details of the physiological mechanisms over decades are often lacking for understanding long-term growth responses to management.
Here, we examined tree-ring growth patterns and stable isotopes of cellulose (delta 13C(cell) and delta 18O(cell)) in a thinning and fertilization controlled experiment where growth increased substantially in response to treatments to elucidate physiological data and to test the dual isotope approach for uses in other locations.
delta 13C(cell) and delta 18O(cell) results indicated that fertilization caused an increase in intrinsic water-use efficiency through increases in photosynthesis (A) for the first 3 yr. The combination treatment caused a much larger increase in A and water-use efficiency. Only the thinning treatments showed consistent significant increases in delta 18O(cell) above controls. Changes in canopy microclimate are the likely drivers for delta 18O(cell) increases with decreases in relative humidity and increases in leaf temperature associated with thinning being the most probable causes.
Tree-ring isotopic records, particularly delta 13C(cell), remain a viable way to reconstruct long-term physiological mechanisms affecting tree carbon gain in response to management and climate fluctuations.

AB p53 coordinates the expression of an intricate network of genes in response to stress signals. Sequence-specific DNA binding is essential for p53-mediated tumor suppression. We evaluated the impact of single-nucleotide polymorphisms (SNPs) in p53 response elements (p53RE) on DNA binding and gene expression in response to DNA damage. Using a bioinformatics approach based on incorporating p53 binding strength into a position weight matrix, we selected 32 SNPs in putative and validated p53REs. The microsphere assay for protein-DNA binding (MAPD) and allele-specific expression analysis was employed to assess the impact of SNPs on p53-DNA binding and gene expression, respectively. Comparing activated p53 binding in nuclear extracts from doxorubicin- or ionizing radiation (IR)-treated human cells, we observed little difference in binding profiles. Significant p53 binding was observed for most polymorphic REs and several displayed binding comparable to the p21 RE. SNP alleles predicted to lower p53 binding indeed reduced binding in 25 of the 32 sequences. Chromatin immunoprecipitation-sequencing in lymphoblastoid cells confirmed p53 binding to seven polymorphic p53 REs in response to doxorubicin. In addition, five polymorphisms were associated with altered gene expression following doxorubicin treatment. Our findings demonstrate an effective strategy to identify and evaluate SNPs that may alter p53-mediated stress responses.

AB Pesticide contamination of surface waters has been a global concern for decades. In agricultural areas, pesticides enter receiving waters through irrigation and storm runoff, spray drift, or even atmospheric deposition. Management practices incorporating vegetation and phytoremediation have demonstrated success in reducing pesticide loads to rivers, lakes, and streams. This chapter will focus on a variety of vegetative management practices (e.g. constructed wetlands, drainage ditches, and rice fields) which have been studied in the intensively cultivated Mississippi Delta. Summaries of research results will be presented, as well as potential future directions for additional research.

AB Contamination from pesticide and nutrient applications to orchard crops is a major water quality issue in California. The goals of this study were to compare pesticide concentrations in water and sediment in runoff from organic and conventional walnut orchards and to compare the observed concentrations to water quality criteria and aquatic life benchmarks. Water and sediment samples were collected from five orchards over two years. Slightly lower, but not significantly different, pesticide concentrations for several pesticides (chlorpyrifos, diazinon, dimethoate, lambda-cyhalothrin, and esfenvalerate) in runoff from organic orchards were measured compared to the conventional orchards. Average concentrations of bifenthrin in sediment were statistically significantly lower (p < 0.05) at the organic sites compared to the conventional sites. This work indicates that BMP implementation and organic farming practices are effective in minimizing concentrations of pesticides in orchard runoff.

AB Pesticide use in paddy rice production may contribute to adverse ecological effects in surface waters. Risk assessments conducted for regulatory purposes depend on the use of simulation models to determine predicted environment concentrations (PEC) of pesticides. Often tiered approaches are used, in which assessments at lower tiers are based on relatively simple models with conservative scenarios, while those at higher tiers have more realistic representations of physical and biochemical processes. This chapter reviews models commonly used for predicting the environmental fate of pesticides in rice paddies. Theoretical considerations, unique features, and applications are discussed. This review is expected to provide information to guide model selection for pesticide registration, regulation, and mitigation in rice production areas.

AB Pyrethroid insecticides have been linked to widespread aquatic toxicity in California's urban watersheds. To assist with the identification of the specific applications or activities linked to pyrethroids discharges, a conceptual model of the transport of pyrethroids from urban areas to surface waters was developed. This model is based on a review of scientific and engineering literature, pesticide product labels, California pesticide sales and reported use data, pesticide user surveys, and unpublished data from municipal urban runoff programs and municipal wastewater treatment plants. The conceptual model categorizes urban pesticide use patterns and disposal practices, and identifies pathways linking pesticide applications with surface waters. The model assumes that the bulk of pesticide applications are made to sites specified on product labels, but considers both legal and illegal disposal practices. The model was developed to serve as a tool to prioritize further investigations of use patterns, formulations, and transport mechanisms, and to develop measures to prevent and respond to water quality and compliance problems associated with urban pyrethroid use.

AB Solar UV radiation, climate and other drivers of global change are undergoing significant changes and models forecast that these changes will continue for the remainder of this century. Here we assess the effects of solar UV radiation on biogeochemical cycles and the interactions of these effects with climate change, including feedbacks on climate. Such interactions occur in both terrestrial and aquatic ecosystems. While there is significant uncertainty in the quantification of these effects, they could accelerate the rate of atmospheric CO2 increase and subsequent climate change beyond current predictions. The effects of predicted changes in climate and solar UV radiation on carbon cycling in terrestrial and aquatic ecosystems are expected to vary significantly between regions. The balance of positive and negative effects on terrestrial carbon cycling remains uncertain, but the interactions between UV radiation and climate change are likely to contribute to decreasing sink strength in many oceanic regions. Interactions between climate and solar UV radiation will affect cycling of elements other than carbon, and so will influence the concentration of greenhouse and ozone-depleting gases. For example, increases in oxygen-deficient regions of the ocean caused by climate change are projected to enhance the emissions of nitrous oxide, an important greenhouse and ozone-depleting gas. Future changes in UV-induced transformations of aquatic and terrestrial contaminants could have both beneficial and adverse effects. Taken in total, it is clear that the future changes in UV radiation coupled with human-caused global change will have large impacts on biogeochemical cycles at local, regional and global scales.

AB With the growing capacity in biodiesel production and the resulting glut of the glycerol by-product, there is increasing interest in finding alternative uses for crude glycerol. One option may be to burn it locally for combined process heat and power, replacing fossil fuels and improving the economics of biodiesel production. However, due to its low energy density, high viscosity, and high auto-ignition temperature, glycerol is difficult to burn. Additionally, the composition of the glycerol by-product can change dramatically depending upon the biodiesel feedstock (e. g., vegetable oils or rendered animal fats), the catalyst used, and the degree of post-reaction cleanup (e. g., acidulation and demethylization). This paper reports the results of experiments to (1) develop a prototype high-swirl refractory burner designed for retrofit applications in commercial-scale fire-tube package boilers, and (2) provide an initial characterization of emissions generated during combustion of crude glycerol in a laboratory-scale moderate-swirl refractory- lined furnace. We report a range of emissions measurements, including nitrogen oxides, total hydrocarbons, and particle mass for two grades of crude glycerol (methylated and demethylated) and compare these to No. 2 fuel oil and propane. We also present preliminary data on the emissions of select carbonyls (by cartridge DNPH). Results indicate that a properly designed refractory burner can provide the thermal environment to effectively combust glycerol, but that high particulate emissions due to residual catalysts are likely to be an issue for crude glycerol combustion.

AB Exposure to 6-propyl-2-thio-uracil (PTU), a neonatal goitrogen, leads to increased testis size and sperm production in rodents. Akt1, a gene involved in cell survival and proliferation is also phosphorylated by thyroxine (T(4)). Therefore, we examined the requirement for Akt1 in germ cell survival following PTU-induced hypothyroidism. Experiments were performed using Akt1+/+, Akt1+/-, and Akt1-/- mice. PTU was administered (0.01% w/v) via the drinking water of dams from birth to PND21. At PND15,T(4) serum levels were similar in all control groups, and significantly lower in all exposed groups with a dramatic decrease in Akt1-/- mice. PTU-exposed Akt1-/- testes displayed smaller tubules, increased apoptosis, delayed lumen formation, and increased inhibin B and AMH mRNA. Relative adult testis weights were similar in all exposure groups: however, no increase in daily sperm production was observed in PTU-exposed Akt1-/- mice. In conclusion, Akt1 contributes to the effects of thyroid hormone on postnatal testis development. (C) 2010 Elsevier Inc. All rights reserved.

AB Chlorination of drinking water yields hundreds of disinfection by-products (DBPs). Among the DBPs, four trihalomethanes (THMs; chloroform, bromodichloromethane, chlorodibromomethane, bromoform) and five haloacetic acids (HAAs; chloroacetic, dichloroacetic, trichloroacetic, bromoacetic, and dibromoacetic acid) are U.S. EPA regulated. We assessed the combined toxicity of these DBPs. F344 rats were treated with mixtures of the four THMs (THM4), the five HAAs (HAA5), or nine DBPs (DBP9; THM4 + HAAS). Mixtures were administered in 10% Alkamuls (R) EL-620 daily by gavage on gestation days 6-20. Litters were examined postnatally. All three mixtures caused pregnancy loss at >= 613 mu mol/kg/day. In surviving litters, resorption rates were increased in groups receiving HAA5 at 615 mu mol/kg/day and DBP9 at 307 mu mol/kg/day. HAA5 caused eye malformations (anophthalmia, microphthalmia) at >= 308 mu mol/kg/day. Thus, both HAAs and THMs contributed to DBP9-induced pregnancy loss. The presence of THMs in the full mixture, however, appeared to reduce the incidence of HAA-induced eye defects. Published by Elsevier Inc.

AB This study summarizes fish stomach content data from 369,000 fish from 402 species in 1,096 collections and reports on the percentage of individuals with empty stomachs. The mean percentage of individuals with empty stomachs among all species, locations, habitats, seasons, regions, and collection methods was 26.4%. Mean percentage of individuals with empty stomachs varied significantly among fish collection gear types, taxonomic orders, trophic groups, feeding behaviors, and habitats, and with species length at maturity. Most of the variation in percentage of individuals with empty stomachs was explained by species length at maturity, fish collection gear type, and two autecological factors: trophic group (piscivore percentage of individuals with empty stomachs non-piscivore percentage of individuals with empty stomachs) and feeding habitat (water column feeder percentage of individuals with empty stomachs benthic feeder percentage of individuals with empty stomachs). After accounting for variation with fish length, the percentage of individuals with empty stomachs did not vary with the stomach removal collection method (dissection vs. gastric lavage), feeding time (diurnal or nocturnal), or time of collection (day or night). The percentage of individuals with empty stomachs was similar between fresh and saltwater fish, but differed within finer habitat classifications and appeared to follow a general prey availability or productivity gradient: percentage of individuals with empty stomachs of open ocean collections estuary collections, lentic lotic, and pelagic littoral. Gear type (active or passive) was the most influential factor affecting the occurrence of empty stomachs that can be readily controlled by researchers.

AB We present a general conceptual model for communicating aspects of river restoration and management. The model is generic and adaptable to most riverine settings, independent of size. The model has separate categories of natural and social-economic drivers, and management actions are envisioned as modifiers of naturally dynamic systems. The model includes a decision-making structure in which managers, stakeholders, and scientists interact to define management objectives and performance evaluation. The model depicts a stress to the riverine ecosystem as either (1) deviation in the regimes (flow, sediment, temperature, light, biogeochemical, and genetic) by altering the frequency, magnitude, duration, timing, or rate of change of the fluxes or (2) imposition of a hard structural constraint on channel form. Restoration is depicted as naturalization of those regimes or removal of the constraint. The model recognizes the importance of river history in conditioning future responses. Three hierarchical tiers of essential ecosystem characteristics (EECs) illustrate how management actions typically propagate through physical/chemical processes to habitat to biotic responses. Uncertainty and expense in modeling or measuring responses increase in moving from tiers 1 to 3. Social-economic characteristics are shown in a parallel structure that emphasizes the need to quantify trade-offs between ecological and social-economic systems. Performance measures for EECs are also hierarchical, showing that selection of measures depend on participants' willingness to accept uncertainty. The general form is of an adaptive management loop in which the performance measures are compared to reference conditions or success criteria and the information is fed back into the decision-making process.

AB This study examines the validity of the ten species and eight subspecies composing the Dasymutilla bioculata species group. Four lines of evidence are examined: morphological data derived from both sexes; behavioural data derived from the study of mating pairs; geographic distribution; and molecular data derived from the internal transcribed spacers 1 and 2 of the nuclear ribosomal RNA cistron (ITS1 and ITS2). Morphological studies reveal that none of the taxa in question can be consistently diagnosed by any synapomorphies or unique combinations of characters. Mating studies reveal that males of single nominal taxa are attracted to females of multiple nominal taxa, and that females of single nominal taxa attract multiple males. None of the nominal taxa are geographically isolated from the others. Genetic distances between these taxa are significantly lower than those seen in interspecific comparisons of other Dasymutilla species. Based on this evidence, we infer that the taxa in question share a recent common ancestor, and cannot be adequately differentiated using any of the available data sources. Therefore, employing the phylogenetic species concept, Dasymutilla bimaculata Manley & Pitts, Dasymutilla chiron chiron (Blake), Dasymutilla chiron ursula (Cresson), Dasymutilla creusa creusa (Cresson), Dasymutilla creusa bellona (Cresson), Dasymutilla lepeletierii (Fox), Dasymutilla medea (Cresson), Dasymutilla melanippe melanippe Mickel, Dasymutilla melanippe conformis Mickel, Dasymutilla praegrandis praegrandis Mickel, Dasymutilla praegrandis russata Mickel, Dasymutilla pyrrhus (Fox) and Dasymutilla sulcatulla Mickel must be considered junior synonyms of Dasymutilla bioculata (Cresson). We also discuss the identification of this species, as well as subspecific relationships and species-group implications.

AB Neurobehavioral and pathological evaluations of the nervous system are complementary components of basic research and toxicity testing of pharmaceutical and environmental chemicals. While neuropathological assessments provide insight as to cellular changes in neurons, behavioral and physiological methods evaluate the functional consequences of disruption of neuronal communications. The underlying causes of certain behavioral alterations may be understood, but many do not have known direct associations with specific brain pathologies. In some cases, however, rapidly expanding mouse models (transgenic, knock-out) are providing considerable information on behavioral phenotypes of altered pathology. Behavior represents the integrated sum of activities mediated by the nervous system, and functional tests used for neurotoxicity testing tap different behavioral repertoires. These tests have an advantage over pathologic measures in that they permit repeated evaluation of a single animal over time to determine the onset, progression, duration, and reversibility of a neurotoxic injury. Functional assays range from a screening-level battery of tests to refined procedures to tap specific forms of learning and/or memory. This article reviews common procedures for behavioral toxicity testing and provides examples of chemical-specific neurobehavioral-pathological correlations in order to inform interpretation and integration of neuropathological and behavioral outcomes.

AB This session at the 2010 joint symposium of the Society of Toxicologic Pathology (STP) and the International Federation of Societies of Toxicologic Pathologists (IFSTP) explored modern neuropathology methods for assessing the neurotoxicologic potential of xenobiotics. Conventional techniques to optimally prepare and evaluate the central and peripheral neural tissues while minimizing artifact were reviewed, and optimal schemes were set forth for evaluation of the nervous system during both routine (i.e., general toxicity) studies and enhanced (i.e., specialized neurotoxicity) studies. Stereology was introduced as the most appropriate means of examining the possible impact of toxicants on neural cell numbers. A focused discussion on brain sampling took place among a panel of expert neuroscientists (anatomists and pathologists) and the audience regarding the proper balance between sufficient sampling and cost-and time-effectiveness of the analysis. No consensus was reached on section orientation (coronal sections of both sides vs. a parasagittal longitudinal section with several unilateral hemisections from the contralateral side), but most panelists favored sampling at least 8 sections (or approximately double to triple the current complement) in routine toxicity studies.

AB The continuing education course on Developmental Neurotoxicity Testing (DNT) was designed to communicate current practices for DNT neuropathology, describe promising innovations in quantitative analysis and noninvasive imaging, and facilitate a discussion among experienced neuropathologists and regulatory scientists regarding suitable DNT practices. Conventional DNT neuropathology endpoints are qualitative histopathology and morphometric endpoints of particularly vulnerable sites (e. g., cerebral, cerebellar, or hippocampal thickness). Novel imaging and stereology measurements hold promise for automated analysis of factors that cannot be effectively examined in routinely processed specimens (e. g., cell numbers, fiber tract integrity). The panel recommended that dedicated DNT neuropathology data sets be acquired on a minimum of 8 sections (for qualitative assessment) or 3 sections (for quantitative linear and stereological analyses) using a small battery of stains to examine neurons and myelin. Where guidelines permit discretion, immersion fixation is acceptable for younger animals (postnatal day 22 or earlier), and peripheral nerves may be embedded in paraffin. Frequent concerns regarding DNT data sets include false-negative outcomes due to processing difficulties (e. g., lack of concordance among sections from different animals) and insensitive analytical endpoints (e. g., qualitative evaluation) as well as false-positive results arising from overinterpretation or misreading by inexperienced pathologists.

AB Ultrasonication is an emerging and very effective mechanical pretreatment method to enhance the biodegradability of the sludge, and it would be very useful to all wastewater treatment plants in treating and disposing sewage sludge. Ultrasonication enhances the sludge digestibility by disrupting the physical, chemical and biological properties of the sludge. The degree of disintegration depends on the sonication parameters and also on sludge characteristics, therefore the evaluation of the optimum parameters varies with the type of sonicater and sludge to be treated. The full-scale installations of ultrasonication have demonstrated that there is 50% increase in the biogas generation, and in addition evaluation of energy balance showed that the average ratio of the net energy gain to electric consumed by the ultrasound device is 2.5. This review article summarizes the benefits of ultrasonication of sludge, the effect of sonication parameters, impact of sludge characteristics on sludge disintegration, and thereby the increase in biogas production in anaerobic digester. Due to uncertainty in the unit representation by many researchers and nonavailability of the data, comparison of these results is complicated. Comparison of ultrasonication with other pretreatment options is necessary to evaluate the best economical and environmental pretreatment technology for sludge treatment and disposal. The optimum parameters for the ultrasonication vary with sludge characteristics. (C) 2010 Elsevier B.V. All rights reserved.

DE renewal; force main; rehabilitation; cured-in place; replacement;

AB This paper presents the results of a review of the state of technology for renewal of force mains. Force mains are critical components of many sewer collection systems with significant environmental and cost consequences for failure. The review identified several needs, including the need for rational and common design approaches for rehabilitation systems, quality assurance/quality control procedures, and better practices for operation and maintenance. The difficulty in assessing the condition of sewer force mains, leaving many owners with questions about the integrity of their systems, and the limited amount of technologies available for renewing a deteriorated main, has limited the amount of renewal work in the past. Most of the renewal activity has involved complete replacement of the force main. As the nation's force mains age further, greater emphasis must be placed on finding cost-effective ways to renew these critical assets. Fortunately, new products and technologies are now emerging for condition assessment, as well as rehabilitation. Some newer methods developed for gravity sewers and water distribution systems are being adapted for use in force main rehabilitation but design and performance data gaps remain to be filled.

AB Remediation of streams influenced by mine-drainage may require removal and burial of metal-containing bed sediments. Burial of aerobic sediments into an anaerobic environment may release metals, such as through reductive dissolution of metal oxyhydroxides. Mining-impacted aerobic streambed sediments collected from North Fork Clear Creek, Colorado were held under anaerobic conditions for four months. Eh, pH, and concentrations of Cd, Cu, Fe, Mn, and Zn (filtered at 1.5 mu m, 0.45 mu m, and 0.2 mu m), sulfate, and dissolved organic carbon (DOC) were monitored in stream water/sediment slurries. Two sediment size fractions were examined (2 mm-63 mu m and <63 mu m). Sequential extractions evaluated the mineral phase with which metals were associated in the aerobic sediment. Released Cu was re-sequestered within 5 weeks, while Fe and Mn still were present at 16 weeks. Mn concentration was lower than in the initial stream water at and beyond 14 weeks for the smaller sized sediment. Cd was not released from either sediment size fraction. Zn was released at early times, but concentrations never exceeded those present in the initial stream water and all was re-sequestered over time. The greatest concentrations of Cu, Fe, Mn, and Zn were associated with the Fe/Mn reducible fraction. Sulfate and Fe were strongly correlated (r = 0.90), seeming to indicate anaerobic dissolution of iron oxy-hydroxy-sulfate minerals. DOC and sulfate were strongly correlated (r = 0.81), with iron having a moderately strong correlation with DOG (r = 0.71). Overall concentrations of DOC, sulfate, Cu, Fe, and Zn and pH were significantly higher ( p < 0.05) in the water overlying the small sized sediment samples, while the concentrations of Mn released from the larger sized sediment samples were greater.

AB Assessing the potential threat of fecal contamination in surface water often depends on model forecasts which assume that fecal indicator bacteria (FIB, a proxy for the concentration of pathogens found in fecal contamination from warm-blooded animals) are lost or removed from the water column at a certain rate (often referred to as an "inactivation" rate). In efforts to reduce human health risks in these water bodies, regulators enforce limits on easily-measured FIB concentrations, commonly reported as most probable number (MPN) and colony forming unit (CFU) values. Accurate assessment of the potential threat of fecal contamination, therefore, depends on propagating uncertainty surrounding "true" FIB concentrations into MPN and CFU values, inactivation rates, model forecasts, and management decisions. Here, we explore how empirical relationships between FIB inactivation rates and extrinsic factors might vary depending on how uncertainty in MPN values is expressed. Using water samples collected from the Neuse River Estuary (NRE) in eastern North Carolina, we compare Escherichia coli (EC) and Enterococcus (ENT) dark inactivation rates derived from two statistical models of first-order loss; a conventional model employing ordinary least-squares (OLS) regression with MPN values, and a novel Bayesian model utilizing the pattern of positive wells in an IDEXX Quanti-Tray (R)/2000 test. While our results suggest that EC dark inactivation rates tend to decrease as initial EC concentrations decrease and that ENT dark inactivation rates are relatively consistent across different ENT concentrations, we find these relationships depend upon model selection and model calibration procedures. We also find that our proposed Bayesian model provides a more defensible approach to quantifying uncertainty in microbiological assessments of water quality than the conventional MPN-based model, and that our proposed model represents a new strategy for developing robust relationships between environmental factors and FIB inactivation rates, and for reducing uncertainty in water resource management decisions.

AB Low and negative pressure events in drinking water distribution systems have the potential to result in intrusion of pathogenic microorganisms if an external source of contamination is present (e.g., nearby leaking sewer main) and there is a pathway for contaminant entry (e.g., leaks in drinking water main). While the public health risk associated with such events is not well understood, quantitative microbial risk assessment can be used to estimate such risk. A conceptual model is provided and the state of knowledge, current assumptions, and challenges associated with the conceptual model parameters are presented. This review provides a characterization of the causes, magnitudes, durations and frequencies of low/negative pressure events; pathways for pathogen entry; pathogen occurrence in external sources of contamination; volumes of water that may enter through the different pathways; fate and transport of pathogens from the pathways of entry to customer taps; pathogen exposure to populations consuming the drinking water; and risk associated with pathogen exposure.

AB The H-2-based membrane biofilm reactor (MBfR) was used to remove nitrate and perchlorate from real ion-exchange brine at two different salinities (30- and 50-g/L NaCl). Base production from nitrate reduction to N-2 gas caused the pH to increase, and this exacerbated precipitation of calcium and magnesium carbonates onto the MBfR fibers. The precipitates lowered the H-2 flux to the biofilm and caused a deterioration of denitrification performance that could be reversed by mild citric-acid washing. The addition of acid seems to be the only mechanism to avoid serious precipitation, membrane fouling, and non-optimal pH for denitrification.

AB It is often difficult to know what to measure when conducting a wetland assessment. There are a wide variety of variables to consider across the three main parameters-water, vegetation, and soils. To complicate things even further, the aspect of time and space must be considered if you wish to be able to make sense of your assessment. We present a discussion of water, vegetation, and soils and then give our best judgment of which variables to measure for each, and why some might be more useful than others. The merits and problems with gathering data from single visits versus multiple visits are discussed, as well as the level of expertise needed in some instances for certain variables to be useful. We do not discuss assessment and inventory methods as these will follow once you chose your assessment variables most relevant to your goals.

TI Wetlands Regulation: The Case of Mitigation Under Section 404 of the
Clean Water Act
SO WETLANDS: INTEGRATING MULTIDISCIPLINARY CONCEPTS
LA English
DT Article; Book Chapter
AB The requirement to mitigate impacts to wetlands and streams is a frequently-misunderstood policy with a long and complicated history. We narrate the history of mitigation since the inception of the Clean Water Act Section 404 permit program in 1972, through struggles between the United States Environmental Protection Agency and the United States Army Corps of Engineers (ACOE), through the emerging importance of wetland conservation on the American political landscape, and through the rise of market-based approaches to environmental policy. Mitigation, as it is understood today, was not initially foreseen as a component of the Section 404 permitting program, but was adapted from 1978 regulations issued by the Council on Environmental Quality as a way of replacing the functions of filled wetlands where permit denials were unlikely. The Environmental Protection Agency (USEPA) and the ACOE agreed in 1990 to define mitigation as the three steps of avoidance, minimization, and compensation, principles which must be applied to permit decisions in the form of the environmental criteria in USEPA's 404(b)(1) Guidelines. Through the 1980s and 1990s, the compensation component of mitigation has become nearly the sole focus of mitigation policy development, and has been the subject of numerous guidances and memoranda since 1990. Avoidance and minimization have received far less policy attention, and this lack of policy development may represent a missed opportunity to implement effective wetland conservation.

AB Seagrasses provide important ecological services that directly or indirectly benefit human well-being and the environment. Excess nitrogen inputs are a major cause of eelgrass loss in the marine environment. Here we describe the results of a study aimed at quantifying the extent of eelgrass as a function of predicted watershed-derived nitrogen loading for small-to-medium-sized shallow estuaries in New England. Findings confirm that reduced extent of eelgrass corresponds to increased loading of nitrogen to this class of estuary. At lower levels of nitrogen loading (<= 50 Kg ha(-1) yr(-1)), eelgrass extent is variable and is likely controlled by other ecosystem factors unrelated to water quality. At higher loading rates, eelgrass coverage decreases markedly, with essentially no eelgrass at loading levels >= 100 Kg ha(-1) yr(-1). Published by Elsevier Ltd.

AB A critical aspect of air pollution exposure models is the estimation of the air exchange rate (AER) of individual homes, where people spend most of their time. The AER, which is the airflow into and out of a building, is a primary mechanism for entry of outdoor air pollutants and removal of indoor source emissions. The mechanistic Lawrence Berkeley Laboratory (LBL) AER model was linked to a leakage area model to predict AER from questionnaires and meteorology. The LBL model was also extended to include natural ventilation (LBLX). Using literature-reported parameter values, AER predictions from LBL and LBLX models were compared to data from 642 daily AER measurements across 31 detached homes in central North Carolina, with corresponding questionnaires and meteorological observations. Data was collected on seven consecutive days during each of four consecutive seasons. For the individual model-predicted and measured AER, the median absolute difference was 43% (0.17 h(-1)) and 40% (0.17 h(-1)) for the LBL and LBLX models, respectively. Additionally, a literature-reported empirical scale factor (SF) AER model was evaluated, which showed a median absolute difference of 50% (0.25 h(-1)). The capability of the LBL, LBLX, and SF models could help reduce the AER uncertainty in air pollution exposure models used to develop exposure metrics for health studies.

ID INDUSTRIAL SOURCE APPLICATIONS; DISPERSION MODEL; DEPOSITION; AERMOD
AB Between April 28 and July 19 of 2010, the U.S. Coast Guard conducted in situ oil burns as one approach used for the management of oil spilled after the explosion and subsequent sinking of the BP Deepwater Horizon platform in the Gulf of Mexico. The purpose of this paper is to describe a screening level assessment of the exposures and risks posed by the dioxin emissions from these fires. Using upper estimates for the oil burn emission factor, modeled air and fish concentrations, and conservative exposure assumptions, the potential cancer risk was estimated for three scenarios: inhalation exposure to workers, inhalation exposure to residents on the mainland, and fish ingestion exposures to residents. U.S. EPA's AERMOD model was used to estimate air concentrations in the immediate vicinity of the oil burns and NOAA's HYSPLIT model was used to estimate more distant air concentrations and deposition rates. The lifetime incremental cancer risks were estimated as 6 x 10(-8) for inhalation by workers, 6 x 10(-12) for inhalation by onshore residents, and 6 x 10(-8) for fish consumption by residents. For all scenarios, the risk estimates represent upper bounds and actual risks would be expected to be less.

AB Emissions from the in situ burning of oil in the Gulf of Mexico after the catastrophic failure of the Deepwater Horizon drilling platform were sampled for polychlorinated dibenzodioxins and polychlorinated dibenzofurans (PCDD/PCDF). A battery-operated instrument package was lofted into the plumes of 27 surface oil fires over a period of four days via a tethered aerostat to determine and characterize emissions of PCDD/PCDF. A single composite sample resulted in an emission factor of 2.0 ng toxic equivalency (TEQ) per kg of carbon burned, or 1.7 ng TEO per kg of oil burned, determined by a carbon balance method. Carbon was measured as CO(2) plus particulate matter, the latter of which has an emission factor of 0.088 kg/kg carbon burned. The average plume concentration approximately 200-300 m from the fire and about 75-200 m above sea level was <0.0002 ng TEQ/m(3).

AB Batch reactor experiments were performed to determine the effects of solids on the oxidation of tetracholoroethylene (PCE) by sodium persulfate in aqueous solution. Based on the rates of PCE degradation and chloride formation, PCE oxidation by heat-activated sodium persulfate at 50 degrees C in the presence of solids ranged from no detectable oxidation of PCE to the levels observed in water-only reactors. Repeated doses of sodium persulfate, undertaken to overcome the inherent solids oxidant demand, improved the rate and extent of PCE oxidation in reactors containing reference solids; however, no improvement was observed in reactors containing field soils. Additionally, no improvements in PCE oxidation were observed after pretreating Great Lakes and Appling soils with ca. 15 g/kg of sodium persulfate or 30% hydrogen peroxide to remove oxidizable fractions, or acetic acid to remove the carbonate fraction. Based on these results, in situ treatment of Great Lakes and Appling soils with heat-activated sodium persulfate is not anticipated to result in substantial PCE oxidation, while in situ treatment of Fort Lewis soils is anticipated to result in PCE oxidation. This work demonstrates the need to perform soil-specific contaminant treatability tests rather than soil oxidant demand tests when determining oxidant dosage requirements.

AB Background: The National Children's Study proposes to investigate biological, chemical, physical, and psychosocial environmental exposures and their role on health outcomes in pregnant women and children. One specific area of concern is contaminant exposure through the ingestion of solid foods. National food contaminant databases may miss dietary exposures unique to specific communities and sources of food.
Objective: The purpose of this study was to evaluate the feasibility of community food item collection for the assessment of pesticide exposure in pregnant women and young children.
Methods: A prospective observational design was used to test the food collection protocol in mothers (n = 45) of children aged 15-24 months in Salt Lake City, Utah. Foods for collection were based on: 1) frequency of different foods consumed by the target population as determined by the National Health and Nutrition Examination Survey data; 2) child food frequency questionnaire; and 3) likelihood of pesticide contamination in the foods. Assessment measures included: demographics, environmental health survey, quality assurance checklist, and participant evaluation form.
Results: An average of three food items were obtained from 44 households, yielding a collection rate of 97.8%. Overall, 100% of the food samples were rated as acceptable. Moreover, a vast majority of mothers reported that the study was not burdensome (95.5%) and that preparing the food sample was easy (93.2%).
Conclusions: This study suggests that the community food item collection methodology shows promise as a low-burden approach for capturing dietary exposures on a household level, and appears to be a feasible tool for large population studies to assess dietary exposures unique to specific communities.

AB Biomarkers are useful exposure surrogates given their ability to integrate exposures through all routes and to reflect interindividual differences in toxicokinetic processes. Also, biomarker concentrations tend to vary less than corresponding environmental measurements, making them less-biasing surrogates for exposure. In this article, urinary PAH biomarkers (namely, urinary naphthalene [U-Nap]; urinary phenanthrene [U-Phe]; 1-hydroxypyrene [1-OH-Pyr]; and 1-, (2+3)-, 4-, and 9-hydroxyphenanthrene [1-, (2+3)-, 4-, and 9-OH-Phe]) were evaluated as surrogates for exposure to hot asphalt emissions using data from 20 road-paving workers. Linear mixed-effects models were used to estimate the within- and between-person components of variance for each urinary biomarker. The ratio of within- to between-person variance was then used to estimate the biasing effects of each biomarker on a theoretical exposure-response relationship. Mixed models were also used to estimate the amounts of variation in Phe metabolism to individual OH-Phe isomers that could be attributed to Phe exposure (as represented by U-Phe concentrations) and covariates representing time, hydration level, smoking status, age, and body mass index. Results showed that 1-OH-Phe, (2+3)-OH-Phe, and 1-OH-Pyr were the least-biasing surrogates for exposure to hot asphalt emissions, and that effects of hydration level and sample collection time substantially inflated bias estimates for the urinary biomarkers. Mixed-model results for the individual OH-Phe isomers showed that between 63% and 82% of the observed biomarker variance was collectively explained by Phe exposure, the time and day of sample collection, and the hydration level, smoking status, body mass index, and age of each worker. By difference, the model results also showed that, depending on the OH-Phe isomer, a maximum of 6-23% of the total biomarker variance was attributable to differences in unobserved toxicokinetic processes between the workers. Therefore, toxicokinetic processes are probably less influential on urinary biomarker variance than are exposures and observable covariate effects. The methods described in this analysis should be considered for the selection and interpretation of biomarkers as exposure surrogates in future exposure investigations.

AB Understanding the impacts of climate change on people and the environment requires an understanding of the dynamics of both climate and land use/land cover changes. A range of future climate scenarios is available for the conterminous United States that have been developed based on widely used international greenhouse gas emissions storylines. Climate scenarios derived from these emissions storylines have not been matched with logically consistent land use/cover maps for the United States. This gap is a critical barrier to conducting effective integrated assessments. This study develops novel national scenarios of housing density and impervious surface cover that are logically consistent with emissions storylines. Analysis of these scenarios suggests that combinations of climate and land use/cover can be important in determining environmental conditions regulated under the Clean Air and Clean Water Acts. We found significant differences in patterns of habitat loss and the distribution of potentially impaired watersheds among scenarios, indicating that compact development patterns can reduce habitat loss and the number of impaired watersheds. These scenarios are also associated with lower global greenhouse gas emissions and, consequently, the potential to reduce both the drivers of anthropogenic climate change and the impacts of changing conditions. The residential housing and impervious surface datasets provide a substantial first step toward comprehensive national land use/land cover scenarios, which have broad applicability for integrated assessments as these data and tools are publicly available.

AB Background: A high body-mass index (BMI, the weight in kilograms divided by the square of the height in meters) is associated with increased mortality from cardiovascular disease and certain cancers, but the precise relationship between BMI and all-cause mortality remains uncertain.
Methods: We used Cox regression to estimate hazard ratios and 95% confidence intervals for an association between BMI and all-cause mortality, adjusting for age, study, physical activity, alcohol consumption, education, and marital status in pooled data from 19 prospective studies encompassing 1.46 million white adults, 19 to 84 years of age (median, 58).
Results: The median baseline BMI was 26.2. During a median follow-up period of 10 years (range, 5 to 28), 160,087 deaths were identified. Among healthy participants who never smoked, there was a J-shaped relationship between BMI and all-cause mortality. With a BMI of 22.5 to 24.9 as the reference category, hazard ratios among women were 1.47 (95 percent confidence interval [CI], 1.33 to 1.62) for a BMI of 15.0 to 18.4; 1.14 (95% CI, 1.07 to 1.22) for a BMI of 18.5 to 19.9; 1.00 (95% CI, 0.96 to 1.04) for a BMI of 20.0 to 22.4; 1.13 (95% CI, 1.09 to 1.17) for a BMI of 25.0 to 29.9; 1.44 (95% CI, 1.38 to 1.50) for a BMI of 30.0 to 34.9; 1.88 (95% CI, 1.77 to 2.00) for a BMI of 35.0 to 39.9; and 2.51 (95% CI, 2.30 to 2.73) for a BMI of 40.0 to 49.9. In general, the hazard ratios for the men were similar. Hazard ratios for a BMI below 20.0 were attenuated with longer-term follow-up.
Conclusions: In white adults, overweight and obesity (and possibly underweight) are associated with increased all-cause mortality. All-cause mortality is generally lowest with a BMI of 20.0 to 24.9.

AB During the past 60 years, afforestation has transformed Israel's landscape, with forests planted or planned on 10% of the country's land, much of it with less than 300 mm of annual precipitation. After early efforts to establish a successful commercial timber industry failed, recreation and ecosystem services came to dominate forestry policy objectives. Given Israel's status as a 'developing country' under the Kyoto Protocol, forests' economic potential through carbon sequestration has been explored, but has not yet proven to be compelling. Several considerations cooled initial enthusiasm for seeking international carbon credits through afforestation. These include administrative obstacles associated with international accreditation, limited potential economic profitability, and ethical considerations. Rather, a voluntary offsetting program was adopted, allowing donors to plant trees in Israel, that balance individual carbon emissions. Afforestation in drylands exhibit meaningful potential to counteract chronic carbon loss due to land degradation. As trees planted in Israel's semi-arid regions exhibit surprisingly high carbon sequestration properties that are comparable to forests in temperate Europe, the potential for offsetting may become a growing factor in local forestry policy once Israel begins to regulate CO2 emissions.

AB Aquatic ecosystems and their fauna are vulnerable to a variety of climate-related changes. Benthic macroinvertebrates are used frequently by water-quality agencies to monitor the status of aquatic resources. We used several regionally distributed state bioassessment data sets to analyze how climate change might influence metrics used to define ecological condition of streams. Many widely used, taxonomically based metrics were composed of both cold- and warm-water-preference taxa, and differing responses of these temperature-preference groups to climate-induced changes in stream temperatures could undermine assessment of stream condition. Climate responsiveness of these trait groups varied among states and ecoregions, but the groups generally were sensitive to changing temperature conditions. Temperature sensitivity of taxa and their sensitivity to organic pollution were moderately but significantly correlated. Therefore, metrics selected for condition assessments because taxa are sensitive to disturbance or to conventional pollutants also were sensitive to changes in temperature. We explored the feasibility of modifying metrics by partitioning components based on temperature sensitivity to reduce the likelihood that responses to climate change would confound responses to impairment from other causes and to facilitate tracking of climate-change-related taxon losses and replacements.

AB Analyses of long-term data are an important component of climate-change research because they can help further our understanding of the effects of climate change and can help establish expectations for biological responses to future climate changes. We used macroinvertebrate data to assess whether biological trends associated with directional climate change could be detected in routine biomonitoring data from Maine, North Carolina, and Utah. We analyzed data from 8 long-term biomonitoring sites that had 9 to 22 y of data, and focused on thermal-preference metrics based on cold- and warm-water-preference trait groups. The thermal-preference metrics were derived primarily from weighted-average or generalized-linear-model inferences based on data from each state database and are region specific. Long-term trends varied across sites and regions. At some sites, the thermal-preference metrics showed significant patterns that could be interpreted as being related to directional climate change, whereas at others, patterns were not as expected or were not evident. The strongest trends occurred at 2 Utah sites that had >= 14 y of data. At these sites, cold-water taxa were negatively correlated with air temperature, and, when years were grouped into hottest- and coldest-year samples, were strongly reduced in the hottest-year samples. Results suggest that thermal-preference metrics show promise for application in a biomonitoring context to differentiate climate-related responses from other stressors.

AB To minimize concerns about the ecological consequences of wind and insect dispersal of pollen and the potential of gene flow from experimental genetically modified (GM) crops to compatible relatives, we have modified outdoor sunlit open top chambers (OTCs) for use with GM plants. We have redesigned 21 cylindrical OTCs, commonly used to study the effects of atmospheric pollutants, by adding (1) a pollen filter at the top of each unit to minimize the possibility of the escape of GM pollen; with pollen filters in place, the OTCs are referred to as mesocosms, (2) an evaporative cooler to help mitigate elevated temperatures during the summer months, and (3) an automated watering system that eliminates the need to enter a mesocosm for irrigation during pollination, thereby minimizing potential pollen escape and entry of insect pollinators. Each sunlit mesocosm contains three large plastic pots (each with 1.2-m(2) surface area) that simulate field plots and that contain a constructed plant community. For example, the community may consist of a GM and a non-GM cultivar of canola (Brassica napus), compatible weedy relatives, and non-compatible species that may be found in mesic disturbed areas such as roadsides or ditches beyond crop fields. The sunlit mesocosms provide a well-replicated outdoor testing system that confines pollen and that can be used to precede or supplement field tests that evaluate the potential ecological consequences of transgenic crops. The mesocosms are proposed as test systems in which transgenic crops and other plants (e. g., biofuel crops) that have been proposed to be grown in new geographies, or plants that produce novel compounds, may be studied to evaluate their potential effects on plant communities. The pollen confinement and insect exclusion features of our mesocosms may also minimize exposure of sensitive humans and insect pollinators to pollen and cellular debris from other plant parts.

AB The Ysleta del Sur Pueblo Environmental Management Office utilized passive air samplers to collect baseline data that can be used in the characterization of Tribal community exposures to ambient air toxics. These passive devices were deployed at ten separate sites. Five of these sites are representative of a housing subdivision (Old Reservation) that is located within the city limits of El Paso, TX, which is characterized as urban/suburban. The remaining five sites are situated in another housing subdivision (New Reservation) that is approximately 8 km southeast, in the city of Socorro, TX, in a rural area surrounded by agricultural fields. The project consisted of two distinct study phases, with each phase corresponding to different weather seasons. The first phase occurred from June through August (warm season), and the second phase occurred from November through February (cool season). During each study phase, passive samplers were deployed for 72 h on five separate occasions, mostly at 18-day intervals. Also, conventional 24-h canister monitoring was conducted at one of the monitoring sites in the Old Reservation for a period of 1 year with data collection occurring once every 6 days. Measurements from the two methods occurring during overlapping monitoring periods were found to be comparable, as were the estimates of precision for each method. Monitoring results indicated significant differences in concentrations of most volatile organic chemicals between reservations and between seasons, with automotive emissions the likely major determinant of levels of the majority of the quantifiable compounds.

AB Pulmonary arterial hypertension (PAH) is a life-threatening disease that leads to progressive pulmonary hypertension, right heart failure, and death. Endothelial dysfunction and inflammation were implicated in the pathogenesis of PAH. Epoxyeicosatrienoic acids (EETs), products of the cytochrome P450 epoxygenase metabolism of arachidonic acid, are potent vasodilators that possess anti-inflammatory and other protective properties in endothelial cells. We investigated whether gene delivery with the human cytochrome P450 epoxygenase 2J2 (CYP2J2) ameliorates monocrotaline (MCT)-induced pulmonary hypertension in rats. Significant pulmonary hypertension developed 3 weeks after the administration of MCT, but gene therapy with CYP2J2 significantly attenuated the development of pulmonary hypertension and pulmonary vascular remodeling, without causing changes in systemic arterial pressure or heart rate. These effects were associated with increased pulmonary endothelial NO synthase (eNOS) expression and its activity, inhibition of inflammation in the lungs, and transforming growth factor (TGF)-beta/type II bonemorphogenetic protein receptor (BMPRII)-drosophila mothers against decapentaplegic proteins (Smads) signaling. Collectively, these data suggest that gene therapy with CYP2J2 may have potential as a novel therapeutic approach to this progressive and oftentimes lethal disorder.

AB Ozone and particulate matter, PM(2.5), are co-pollutants that have long been associated with increased public health risks. Information on concentration levels for both pollutants comes from two sources: monitoring sites and output from complex numerical models that produce concentration surfaces over large spatial regions. In this paper, we offer a fully-model-based approach for fusing these two sources of information for the pair of co-pollutants which is computationally feasible over large spatial regions and long periods of time. Due to the association between concentration levels of the two environmental contaminants, it is expected that information regarding one will help to improve prediction of the other. Misalignment is an obvious issue since the monitoring networks for the two contaminants only partly intersect and because the collection rate for PM(2.5) is typically less frequent than that for ozone.
Extending previous work in Berrocal, Gelfand and Holland (2010), we introduce a bivariate downscaler that provides a flexible class of bivariate space-time assimilation models. We discuss computational issues for model fitting and analyze a dataset for ozone and PM(2.5) for the ozone season during year 2002. We show a modest improvement in predictive performance, not surprising in a setting where we can anticipate only a small gain.

AB With the advent of transgenic crops, genetically modified, herbicide-resistant Brassica napus has become a model system for examining the risks and potential ecological consequences of escape of transgenes from cultivation into wild compatible species. Escaped transgenic feral B. napus and hybrids with compatible weedy species have been identified outside of agriculture and without the apparent selection for herbicide resistance. However, herbicide (glyphosate) exposure can extend beyond crop field boundaries, and a drift-level of herbicide could function as a selective agent contributing to increased persistence of transgenes in the environment.
The effects of a drift level (0 center dot 1 x the field application rate) of glyphosate herbicide and varied levels of plant competition were examined on plant fitness-associated traits and gene flow in a simulated field plot, common garden experiment. Plants included transgenic, glyphosate-resistant B. napus, its weedy ancestor B. rapa, and hybrid and advanced generations derived from them.
The results of this experiment demonstrate reductions in reproductive fitness for non-transgenic genotypes and a contrasting increase in plant fitness for transgenic genotypes as a result of glyphosate-drift treatments. Results also suggest that a drift level of glyphosate spray may influence the movement of transgenes among transgenic crops and weeds and alter the processes of hybridization and introgression in non-agronomic habitats by impacting flowering phenology and pollen availability within the community.
The results of this study demonstrate the potential for persistence of glyphosate resistance transgenes in weedy plant communities due to the effect of glyphosate spray drift on plant fitness. Additionally, glyphosate drift has the potential to change the gene-flow dynamics between compatible transgenic crops and weeds, simultaneously reducing direct introgression into weedy species while contributing to an increase in the transgenic seed bank.

Two competing effects may account for the variation in disinfection kinetic parameters: (i) increasing kinetics (disinfection rate constant [k] increased, lag coefficient [b] decreased) with increasing phosphate concentration and (ii) decreasing kinetics (k decreased, b increased) with increasing ionic strength. The results support development of a standard medium for evaluating disinfection kinetics in drinking water.

AB The Mechanistic Indicators of Childhood Asthma (MICA) study in Detroit Michigan introduced a participant-based approach to reduce the resource burden associated with collection of indoor and outdoor residential air sampling data A subset of participants designated as MICA-Air conducted indoor and outdoor residential sampling of nitrogen dioxide (NO(2)) volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs) This participant-based methodology was subsequently adapted for use in the Vanguard phase of the US National Children s Study The current paper examines residential indoor and outdoor concentrations of these pollutant species among health study participants in Detroit Michigan
Pollutants measured under MICA-Air agreed well with other studies and continuous monitoring data collected in Detroit For example NO(2) and BTEX concentrations reported for other Detroit area monitoring were generally within 10-15% of indoor and outdoor concentrations measured in MICA-Air households Outdoor NO(2) concentrations were typically higher than indoor NO(2) concentration among MICA-Air homes with a median indoor/outdoor (I/O) ratio of 06 in homes that were not Impacted by environmental tobacco smoke (ETS) during air sampling Indoor concentrations generally exceeded outdoor concentrations for VOC and PAH species measured among non-ETS homes in the study I/O ratios for BTEX species (benzene toluene ethylbenzene and m/p- and o-xylene) ranged from 1 2 for benzene to 3 1 for toluene Outdoor NO(2) concentrations were approximately 4 5 ppb higher on weekdays versus weekends As expected I/O ratios pollutants were generally higher for homes impacted by ETS
These findings suggest that participant-based air sampling can provide a cost-effective alternative to technician-based approaches for assessing Indoor and outdoor residential air pollution in community health studies We also introduced a technique for estimating daily concentrations at each home by weighting 2- and 7-day integrated concentrations using continuous measurements from regulatory monitoring sites This approach may be applied to estimate short-term daily or hourly pollutant concentrations in future health studies (C) 2010 Elsevier Ltd All rights reserved

AB BACKGROUND: There continue to be many efforts around the world to develop assays that are shorter than the traditional embryofetal developmental toxicity assay, or use fewer or no mammals, or use less compound, or have all three attributes. Each assay developer needs to test the putative assay against a set of performance standards, which traditionally has involved testing the assays against a list of compounds that are generally recognized as "positive'' or "negative'' in vivo. However, developmental toxicity is highly conditional, being particularly dependent on magnitude (i.e. dose) and timing of exposure, which makes it difficult to develop lists of compounds neatly assigned as developmental toxicants or not. APPROACH: Here we offer an alternative approach for the evaluation of developmental toxicity assays based on exposures. Exposures are classified as "positive'' or "negative'' in a system, depending on the compound and the internal concentration. Although this linkage to "internal dose'' departs from the recent approaches to validation, it fits well with widely accepted principles of developmental toxicology. CONCLUSIONS: This paper introduces this concept, discusses some of the benefits and drawbacks of such an approach, and lays out the steps we propose to implement it for the evaluation of developmental toxicity assays.

AB We compared the species composition and abundance of the total nekton community, using the Bray-Curtis similarity coefficient, and mean total nekton, fish and crab species richness, abundance and biomass, and shrimp abundance across four intertidal habitats in a US Pacific Northwest estuary: (i) eelgrass (Zostera marina); (ii) burrowing mud shrimp (Upogebia pugettensis); (iii) burrowing ghost shrimp (Neotrypaea californiensis); and (iv) unvegetated sand. Field sampling was conducted during daytime high tides, and was quantitative, stratified-by-habitat, randomized, and estuary-wide. More than 10 000 nekton specimens belonging to 64 taxa were collected in 454 samples during 10 sampling periods, each approximately one-month-long (from June to November), over 3 years (1998-2000). Non-metric multidimensional scaling analyses revealed annually recurring across-habitat patterns in total nekton Bray-Curtis similarity. Two-way (habitat, year) analyses of variance revealed annually recurring across-habitat patterns on 10 indicators of nekton-habitat quality and preference. Total nekton species richness, abundance, and biomass were, respectively, on average, 8 x, 25 x, and 25 x greater in eelgrass, 4 x, 6 x, and 5 x greater in mud shrimp, and 2 x, 3 x, and 2 x greater in ghost shrimp, than in sand habitat. Our findings validate the ecological relevance of our habitats to nekton, and suggest they can serve as elements in ecological periodic tables of nekton habitat usage.

AB A growing body of evidence from epidemiological and toxicological studies provides a strong link between exposure to ambient particulate matter (PM) of varying size and increased cardiovascular and respiratory morbidity and mortality. This study was designed to evaluate the cardiopulmonary effects of ambient coarse, fine, and ultrafine particles collected in Chapel Hill, NC. Mice were exposed to each size fraction by oropharyngeal instillation. Twenty-four hours later, pulmonary inflammation was assessed by bronchoalveolar lavage and cardiac injury was measured using a Langendorff cardiac perfusion preparation. Recovery of post-ischemic left ventricular developed pressure and infarct size were measured as indeces of cardiac ischemia/reperfusion injury. Coronary flow rate was measured before, during, and after ischemia. We demonstrate that coarse PM caused the most significant pulmonary inflammatory responses. In contrast, hearts from ultrafine-exposed mice had significantly lower post-ischemic functional recovery and greater infarct size, while hearts from coarse and fine PM-exposed mice had no significant responses to ischemia/reperfusion. The coronary flow rate was significantly reduced in the ultrafine PM group. This study shows that exposure of mice to coarse PM results in significant pulmonary toxicity while ultrafine PM appears to enhance cardiac ischemia/reperfusion injury.

AB Formalin-fixed, paraffin-embedded skin tissue sections were collected from a matched cohort of 63 fibromyalgia syndrome (FMS) patients and 49 volunteers from the general population with both alpha1-antitrypsin (AAT) normal and deficiency variants. These tissues were examined for the expression of the broad-spectrum inhibitor AAT, the serine proteinases elastase and tryptase, the proinflammatory cytokines MCP-1 and TNF alpha, the endothelium biomarker VEGF, and the inflammation/nociception-related receptor PAR(2). The most relevant finding of the study was a significantly increased number of mast cells (MCs) in the papillary dermis of all FMS patients (greater than or equal to five to 14 per microscopic high power field) compared to zero to one in controls (p<0.001). MCs strongly stained with tryptase, AAT and PAR(2) antibodies, exhibited a spindle-like shape and were uniformly distributed around blood vessels and appendages. MCP-1 and VEGF expressed weak/moderate positivity in most samples, with a higher expression in controls than in FMS patients (p<0.001 and 0.051, respectively). No differences in elastase and TNF alpha were found between both groups. Moreover, no histological differences were found between samples from AAT deficiency and normal AAT phenotypes. Our results indicate that FMS is a MC-associated condition. MCs are present in skin and mucosal surfaces throughout the human body, and are easily stimulated by a number of physical, psychological, and chemical triggers to degranulate, releasing several proinflammatory products which are able to generate nervous peripheral stimuli causing CNS hypersensitivity, local, and systemic symptoms. Our findings open new avenues of research on FMS mechanisms and will benefit the diagnosis of patients and the development of therapeutics.

AB Trichoderma viride was proved as an effective biocontrol agent against two fungal pathogens, Fusarium oxysporum f. sp. adzuki and Pythium arrhenomanes, infecting soybean. During an in vitro biocontrol test, Trichoderma showed mycoparasitism and destructive control against the tested fungal pathogens. Both the pathogens significantly influence the germination and P. arrhenomanes had a severe effect (only 5% germination). The root system of the soybean plant was poorly developed due to the infection and it exerted a negative influence on the nodulation and further growth phases of the plant. During pot assay along with biocontrol activity, Trichoderma showed growth promoting action on the soybean plant. Trichoderma enhanced growth of shoot and root systems and fruit yield after 12 weeks of growth. Pythium and Fusarium infected plants treated with Trichoderma had similar to 194% and 141% more height than pathogens alone. The fruit yield treated with Trichoderma was similar to 66 per plant whereas the yield was only 41 for a control plant. The plants infected with Pythium and Fusarium and treated with Trichoderma had fruit yields of 43 and 53 respectively and those were 5 and 1.6 times higher than plants infected with pathogens.

AB The extent to which membrane-disrupting agents, such as alamethicin, may alter cofactor transport and influence in vitro kinetic measurements of glucuronidation is a major concern regarding the characterization and extrapolation of inter-and intraspecies pharmacokinetics of bisphenol A (BPA). An additional concern is the omission of a BPA intestinal metabolism component in current pharmacokinetic models used to assess oral exposure. In this study, BPA glucuronidation in native hepatic microsomes from female rat and female human liver displayed higher V(max) values than that in males. In the presence of alamethicin, all hepatic V(max) values increased; however, this increase was disproportionately greater in males and gender differences were no longer observed. Female rats exhibited a much higher K(m) than all other species and genders; the addition of alamethicin had little influence on K(m) values for any of the test systems. The dissimilar K(m) measured for female rat suggests that different UDP-glucuronosyltransferase (UGT) enzyme(s) are involved in BPA glucuronidation. The presence of different UGTs in female rat was confirmed using Hill coefficients measured from diclofenac-mediated chemical inhibition assays within hepatic microsomes and purified human UGT2B7 and UGT2B15. Mixed-gender human intestinal microsomes showed little BPA glucuronidation reactivity compared with those from male rat intestine. Male rat intestinal microsomes in the presence of alamethicin exhibited a V(max) that was nearly 30-fold higher than that for mixed human microsomes. The species and gender metabolic differences we observed between rat and human liver and intestine provide key information for delineating BPA pharmacokinetics needed for human health risk assessment.

AB Plant species richness has declined and composition shifted in response to elevated atmospheric deposition of biologically active nitrogen over much of the industrialized world. Litter thickness, litter nitrogen (N) content, and soil N mineralization rates often remain elevated long after inputs cease, clouding the prospects that plant community diversity and composition would recover should N inputs be reduced. Here we determined how N cycling, litter accumulation, and recruitment limitation influenced community recovery following cessation of long-term N inputs to prairie-like grasslands. We alleviated each of these potential inhibitors through a two-year full-factorial experiment involving organic carbon addition, litter removal, and seed addition. Seed addition had the largest effect on increasing seedling and species numbers and may be necessary to overcome long-term burial of seeds of target perennial grassland species. Litter removal increased light availability and bare sites for colonization, though it had little effect on reducing the biomass of competing neighbors or altering extractable soil N. Nonetheless, these positive influences were enough to lead to small increases in species richness within one year. We found that, although C addition quickly altered many factors assumed favorable for the target community (decreased N availability and biomass of nearby competitors, increased light and site availability), these changes were insufficient to positively impact species richness or seedling numbers over the experimental duration. However, only carbon addition had species-specific effects on the existing plant community, suggesting that its apparent limited utility may be more a result of slow recovery under ambient recruitment rather than from a lack of a restorative effect. There were dramatic interactions among treatments, with the positive effects of litter removal largely negated by carbon addition, and the positive effects of seed addition generally amplified by litter removal. It remains unclear whether each mechanism explored here will induce community recovery, but over different temporal scales. Long-term monitoring will help resolve these remaining questions. Regardless, our results suggest that reversal of species loss and compositional shifts from N deposition in prairies may be more inhibited by habitat fragmentation, recruitment limitation, and long-term suppression of fire than from continued effects of elevated N.

AB BACKGROUND: Diabetes confers an increased risk for cardiovascular effects of airborne particles.
OBJECTIVE: We hypothesized that inhalation of elemental carbon ultrafine particles (UFP) would activate blood platelets and vascular endothelium in people with type 2 diabetes.
METHODS: In a randomized, double-blind, crossover trial, 19 subjects with type 2 diabetes inhaled filtered air or 50 mu g/m(3) elemental carbon UFP (count median diameter, 32 nm) by mouthpiece for 2 hr at rest. We repeatedly measured markers of vascular activation, coagulation, and systemic inflammation before and after exposure.
RESULTS: Compared with air, particle exposure increased platelet expression of CD40 ligand (CD40L) and the number of platelet-leukocyte conjugates 3.5 hr after exposure. Soluble CD40L decreased with UFP exposure. Plasma von Willebrand factor increased immediately after exposure. There were no effects of particles on plasma tissue factor, coagulation factors VII or IX, or D-dimer.
CONCLUSIONS: Inhalation of elemental carbon UFP for 2-hr transiently activated platelets, and possibly the vascular endothelium, in people with type 2 diabetes.

AB BACKGROUND: The prioritization of chemicals for toxicity testing is a primary goal of the U. S. Environmental Protection Agency (EPA) ToxCast (TM) program. Phase I of ToxCast used a battery of 467 in vitro, high-throughput screening assays to assess 309 environmental chemicals. One important mode of action leading to toxicity is endocrine disruption, and the U. S. EPA's Endocrine Disruptor Screening Program (EDSP) has been charged with screening pesticide chemicals and environmental contaminants for their potential to affect the endocrine systems of humans and wildlife.
OBJECTIVE: The goal of this study was to develop a flexible method to facilitate the rational prioritization of chemicals for further evaluation and demonstrate its application as a candidate decision-support tool for EDSP.
METHODS: Focusing on estrogen, androgen, and thyroid pathways, we defined putative endocrine profiles and derived a relative rank or score for the entire ToxCast library of 309 unique chemicals. Effects on other nuclear receptors and xenobiotic metabolizing enzymes were also considered, as were pertinent chemical descriptors and pathways relevant to endocrine-mediated signaling.
RESULTS: Combining multiple data sources into an overall, weight-of-evidence Toxicological Priority Index (ToxPi) score for prioritizing further chemical testing resulted in more robust conclusions than any single data source taken alone.
CONCLUSIONS: Incorporating data from in vitro assays, chemical descriptors, and biological pathways in this prioritization schema provided a flexible, comprehensive visualization and ranking of each chemical's potential endocrine activity. Importantly, ToxPi profiles provide a transparent visualization of the relative contribution of all information sources to an overall priority ranking. The method developed here is readily adaptable to diverse chemical prioritization tasks.

AB BACKGROUND: The mechanisms underlying ozone (O(3))-induced pulmonary inflammation remain unclear. Interleukin-10 (IL-10) is an anti-inflammatory cytokine that is known to inhibit inflammatory mediators.
OBJECTIVES: We investigated the molecular mechanisms underlying interleuken-10 (IL-10)-mediated attenuation of O(3)-induced pulmonary inflammation in mice.
METHODS: Il10-deficient (Il10(-/-)) and wild-type (Il10(+/+)) mice were exposed to 0.3 ppm O(3) or filtered air for 24, 48, or 72 hr. Immediately after exposure, differential cell counts and total protein (a marker of lung permeability) were assessed from bronchoalveolar lavage fluid (BALF). mRNA and protein levels of cellular mediators were determined from lung homogenates. We also used global mRNA expression analyses of lung tissue with Ingenuity Pathway Analysis to identify patterns of gene expression through which IL-10 modifies O(3)-induced inflammation.
RESULTS: Mean numbers of BALF polymorphonuclear leukocytes (PMNs) were significantly greater in Il10(-/-) mice than in Il10(+/+) mice after exposure to O(3) at all time points tested. O(3)-enhanced nuclear NF-kappa B translocation was elevated in the lungs of Il10(-/-) compared with Il10(+/+) mice. Gene expression analyses revealed several IL-10-dependent and O(3)-dependent mediators, including macro-phage inflammatory protein 2, cathepsin E, and serum amyloid A3.
CONCLUSIONS: Results indicate that IL-10 protects against O(3)-induced pulmonary neutrophilic inflammation and cell proliferation. Moreover, gene expression analyses identified three response pathways and several genetic targets through which IL-10 may modulate the innate and adaptive immune response. These novel mechanisms of protection against the pathogenesis of O(3)-induced pulmonary inflammation may also provide potential therapeutic targets to protect susceptible individuals.

AB A dynamic simulation framework is used to compare benefit-cost ratios of riparian restoration investment strategies to pursue ecosystem service benefits. The model is meant to be adaptable to generic restoration planning applications, with the Middle Rio Grande riparian corridor in Albuquerque, New Mexico, U.S.A. presented here as the illustrating case. Model inputs include ecosystem service values from an original choice experiment, values from regional benefit transfer studies, and information from land managers.
The model includes three control variable modules: forest management, river restoration, and recreation infrastructure. Investment influences these modules, which in turn affect ecosystem service flows for the region. The model is exercised to compare a "No-Action" alternative with "Optimal Benefit-Cost Ratio" restoration funding. An extended sensitivity analysis explores a range of both physical and economic assumptions. The analysis has two major outcomes. The first is that directed restoration funding yields significant gains as compared with No-Action for all scenarios tested. The second major finding is that although optimized benefit-cost ratios are above unity for all "states of the world" tested, the ratio itself and funding patterns varied widely. These sensitivities underscore the need for a transparent adaptive management decision process supported by tools aimed not at deterministic prediction, but rather at structuring dialogue and inquiry into issues that defy simple intuition.

AB The availability of wetlands and shallow water habitats significantly influences Gulf of Mexico (GOM) penaeid shrimp fishery productivity. However, the GOM region has the highest rate of wetland loss in the USA. Protection and management of these vital GOM habitats are critical to sustainable shrimp fisheries. Brown shrimp (Farfantepenaeus aztecus) are a major component of GOM fisheries. We present an approach for estimating the areal extent of suitable habitat for post-larval and juvenile brown shrimp in Mobile Bay, Alabama, using an existing habitat suitability index model for the northern GOM calculated from probabilistic survey of water quality and sediment data, land cover data, and submerged aquatic vegetation coverages. This estuarine scale approach is intended to support targeted protection and restoration of these habitats. These analyses indicate that approximately 60% of the area of Mobile Bay is categorized as suitable to near optimal for post-larval and juvenile shrimp and 38% of the area is marginally to minimally suitable. We identify potential units within Mobile Bay for targeted restoration to improve habitat suitability.

AB The volume of sediment required to perform a sediment toxicity bioassay is a major driver of the overall cost associated with that bioassay Sediment volume affects bioassay cost because of sediment collection transportation storage and disposal costs as well as labor costs associated with organism recovery at the conclusion of the exposure The objective of the current study was to evaluate reduced sediment volume versions of the standard U S Environmental Protection Agency (U S EPA) 10 d acute Leptocheirus plumulosus method that uses a beaker size of 1 000 ml and 20 organisms The test design used evaluated the effects of beaker size (250 and 100 ml) and associated sediment volume (75 and 30ml respectively) as well as organism loading density (10 and 20 organisms) on test endpoint responsiveness relative to the standard 10 d test method These comparisons were completed with three different types of contaminated sediments a field collected polycyclic aromatic hydrocarbon (PAH) contaminated sediment a lead spiked control sediment and a control sediment spiked with mineral oil Assessment criteria included test endpoint sensitivity endpoint consistency statistical power water quality and logistical assessments Results indicate that the current U S EPA method is preferable to the reduced sediment volume methods we assessed but that a 250 ml beaker/10 organism experimental design is of comparable utility and may be advantareous when reduced sediment volumes are desirable because of high contaminant (spiking studies) or sediment disposal costs In addition the results of the current study provide toxicity reference values for PAHs lead and an oil surrogate for petroleum hydrocarbons Environ Toxicol Chem 2010 29 2769-2776 (C) 2010 SETAC
