[Ab] Abstract:Inclusion of consumer preferences to disseminate evidence-based psychosocial treatment (EBPT) is crucial to effectively bridge the science-to-practice quality chasm. We examined this treatment gap for insomnia, posttraumatic stress disorder (PTSD), depression, and comorbid symptoms in a sample of 622 young adult veterans through preference in symptom focus, treatment modality, and related gender differences among those screening positive for each problem. Data were collected from veteran drinkers recruited through targeted Facebook advertisements as part of a brief online alcohol intervention. Analyses demonstrated that veterans reported greater willingness to seek insomnia-focused treatment over PTSD- or depression-focused care. Notably, even when participants screened negative for insomnia, they preferred sleep-focused care to PTSD- or depression-focused care. Although one in five veterans with a positive screen would not consider care, veterans screening for both insomnia and PTSD who would consider care had a preference for in-person counseling, and those screening for both insomnia and depression had similar preferences for in-person and mobile app-based/computer self-help treatment. Marginal gender differences were found. Incorporating direct-to-consumer methods into research can help educate stakeholders about methods to expand EBPT access. Though traditional in-person counseling was often preferred, openness to app-based/computer interventions offers alternative methods to provide veterans with EBPTs.

[Ab] Abstract:Although metal(loid) bioaccessibility of ambient particulate matter, with an aerodynamic diameter of <10µm (PM ), has recently received increasing attention, limited research exists into standardising in-vitro methodologies using simulated lung fluid (SLF). Contradictions exist regarding which assay parameters should be adopted. Additionally, potential continuation of metal(loid) dissolution once PM is cleared from the lungs and passed through the gastro-intestinal tract (GIT) has rarely been addressed. The objective of this study was to assess parameters that influence inhalation bioaccessibility in order to develop a conservative assay that is relevant to a human inhalation scenario. To achieve this aim, the effect of solid to liquid (S/L) ratio, extraction time, agitation and five major SLF compositions on the bioaccessibilities of arsenic (As) and lead (Pb) was investigated using PM from three Australian mining/smelting impacted regions. Using the biologically relevant parameters that resulted in the most conservative outcomes, bioaccessibility of metal(loid)s in PM was assessed in SLF, followed by simulated GIT solutions. Results from this study revealed that fluid composition and S/L ratio significantly affected metal(loid) dissolution (p<0.05). The highest Pb bioaccessibility resulted using simulated lung-gastric solution, while that of As resulted using simulated lung-gastric-small intestinal tract solutions. Compared to SLF alone, metal(loid) dissolution using the inhalation-ingestion bioaccessibility assay (IIBA) was significantly higher (p<0.05) for all PM samples.

[Ab] Abstract:In our study, health risk levels of different age groups of residents living in the vicinity of a municipal solid waste incinerator (MSWI) posed by polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) in atmosphere and soil were evaluated. The toxic equivalent concentrations of PCDD/Fs (TEQ) in surrounding atmosphere and soil of studied MSWI were 0.05-0.12 pg I-TEQ Nm and 7.622-15.450 ng I-TEQ kg , respectively. The PCDFs/PCDDs (F/D) values of PCDD/Fs in surrounding atmosphere of studied MSWI ranged from 0.40 to 5.90 with a mean of 1.80, suggesting that the PCDD/Fs mainly came from combustion sources and studied MSWI could be a key source of PCDD/Fs in surrounding atmosphere. The F/D ratios of PCDD/Fs in surrounding soil ranged from 0.18 to 1.81 with a mean of 0.90, suggesting combustion is not the mainly sources of PCDD/Fs in surrounding soil, and studied MSWI may have limited influence on PCDD/Fs in surrounding soil. O8CDD and 2,3,4,7,8-P5CDF could be the total PCDD/Fs and TEQ indicators in surrounding atmosphere of studied MSWI, respectively. The carcinogenic risk (CR) values of PCDD/Fs in surrounding atmosphere and soil for children, teens and adults were 1.24E-06, 9.06E-07 and 4.41E-06, respectively, suggesting that the potential cancer risk occurred but the risk was at acceptable levels for both children and adults (<1.00E-05), and the cancer risk for teens was negligible (<1.00E-06). The non-carcinogenic risk (non-CR) values of three age groups were lower than 1, indicating that no obvious non-carcinogenic effects occurred. Inhalation of air was the largest contributor of health risk (both CR and non-CR) for three age groups. In addition, a comparison of the health risk between PCDD/Fs and other emerging contaminants and traditional pollutants in soil and atmosphere was performed, which will help us have a good view of the health risk levels of PCDD/Fs in surrounding environment of MWSI.

[Ti] Title:Vulnerability and risk of deltaic social-ecological systems exposed to multiple hazards.

[Ab] Abstract:Coastal river deltas are hotspots of global change impacts. Sustainable delta futures are increasingly threatened due to rising hazard exposure combined with high vulnerabilities of deltaic social-ecological systems. While the need for integrated multi-hazard approaches has been clearly articulated, studies on vulnerability and risk in deltas either focus on local case studies or single hazards and do not apply a social-ecological systems perspective. As a result, vulnerabilities and risks in areas with strong social and ecological coupling, such as coastal deltas, are not fully understood and the identification of risk reduction and adaptation strategies are often based on incomplete assumptions. To overcome these limitations, we propose an innovative modular indicator library-based approach for the assessment of multi-hazard risk of social-ecological systems across and within coastal deltas globally, and apply it to the Amazon, Ganges-Brahmaputra-Meghna (GBM), and Mekong deltas. Results show that multi-hazard risk is highest in the GBM delta and lowest in the Amazon delta. The analysis reveals major differences between social and environmental vulnerability across the three deltas, notably in the Mekong and the GBM deltas where environmental vulnerability is significantly higher than social vulnerability. Hotspots and drivers of risk vary spatially, thus calling for spatially targeted risk reduction and adaptation strategies within the deltas. Ecosystems have been identified as both an important element at risk as well as an entry point for risk reduction and adaptation strategies.

[Ab] Abstract:Although a few studies have analyzed the associations between ambient air pollutants and the development of tuberculosis (TB), most have been conducted in the core countries with inconsistent results. In this study, we used a distributed lag non-linear model to investigate the associations between the newly diagnosed TB cases and daily exposure to particulate matter with an aerodynamic diameter of <10µm (PM ), nitrogen dioxide (NO ), and sulfur dioxide (SO ) in Chengdu, a severely polluted city. There were 36,108 newly diagnosed active TB cases from January 1, 2010 to December 31, 2015 in Chengdu. In a single-pollutant model, the cumulative relative risk of active TB cases was 1.06 [lag of 0 to 21days, 95% confidence interval (CI): 1.01-1.11] for each 10µg/m increase in PM above the threshold of 70µg/m ; 1.06 (lag of 0 to 2days, 95% CI: 1.03-1.09) for each 10µg/m increase in NO above the threshold of 40µg/m ; and 1.07 (lag of 0 to 2days, 95% CI: 1.02-1.12) for each 10µg/m increase in SO above the threshold of 60µg/m . Meanwhile, we found a positive association in males after exposure to a 10µg/m increase in SO above the threshold of 60µg/m at a lag of 0 to 2days. Exposure to PM , NO , and SO was associated with an increment in the incidence of active TB cases.

[Ab] Abstract:As a typical test species, Asian Clam (Corbicula fluminea) is widely used in the identification and evaluation of freshwater toxicity. This study provides a summary of the research published from 1979 to 2018. The focus was on the bioaccumulation, morphological and behavioral changes, and biochemical index alterations of Corbicula fluminea to target pollutants (i.e., ammonia, metal(loid)s, and organic chemicals) in surface water and sediment. The applications on the evaluation of actual aquatic pollution, determination of toxicological mechanisms, prediction of toxicity, and bioremediation are also specifically discussed. The primary purpose is to facilitate the comprehensive understanding and accurate application of Corbicula fluminea in freshwater ecotoxicological studies.

[Ab] Abstract:Endocrine disruptors when introduced to waterways have many adverse health effects on wildlife and humans. These health effects vary from neurological, immune, carcinogenic and reproductive disorders. Currently, there are few wastewater treatment facilities that are purposefully treating endocrine disruptors as part of the normal wastewater treatment process. Current literature has shown that endocrine disruptors can be treated using conventional methods. These conventional methods are centered around the denitrification process, which is rarely adopted in Canada. This paper investigates the current wastewater effluent regulations and guidelines in Canada, Ontario and the European Union. The research identifies a policy strategy that would include denitrification in the wastewater treatment process to help eliminate endocrine disruptors and acutely toxic nitrogen based compounds. Our emphasis here is on action possible in the Province of Ontario Canada, give the context of the Great Lakes basin and the potential for early action to stimulate other jurisdictions to follow. Our recommendations while aimed at one jurisdiction, have broad application globally.

[Ab] Abstract:Persistent organic pollutants (POPs) accumulate in the fat tissue of living organisms and are found in relatively high concentrations in animals at the top of the food chain, such as dolphins. The ability of these compounds to interact with the endocrine system of marine mammals constitutes a risk for the reproduction and conservation of species. The La Plata dolphin, Pontoporia blainvillei, is exclusive to the southwestern Atlantic Ocean and is classified on the IUCN red list as a vulnerable species. Blubber, liver, kidney and muscle samples from four P. blainvillei mother-fetus pairs were analyzed to evaluate the transfer of POPs to fetal tissues through the placenta. The presence of POPs in fetal tissues indicates the maternal transfer of compounds. In the pregnant females, blubber was the tissue with POP highest concentration, followed by the liver, kidneys and muscles. In the fetuses, POP accumulation mainly occurred in the blubber followed by the muscles, liver and kidneys. Polychlorinated biphenyls (PCBs) and dichlorodiphenyltrichloroethane (DDTs) were found in all tissues analyzed and had the highest concentrations among all compounds. The main PCB congeners in the fetal samples had five to seven chlorine atoms. The only polybrominated diphenyl ether (PBDE) in the fetal samples was 47 and was found only in blubber. The main DDT metabolite in the fetuses was p,p'-DDE. POP transfer via the placenta occurs in the first months of gestation and increases with fetal development, according to fetus/mother (F/M) ratio: HCB>DDT>PCB>PBDE>Mirex, which may follow the order of the octanol/water partition coefficient (K ) values.

[Ti] Title:Ecotoxicoparasitology of the gastrointestinal tracts of pinnipeds: the effect of parasites on the potential bioavailability of total mercury (THg).

[Ab] Abstract:Acanthocephalans, cestodes, and some species of nematodes acquire nutrients from the lumen contents in the gastrointestinal (GI) tract of their definitive host. These parasites are exposed to toxicants, such as mercury (Hg), through passive or active feeding mechanisms; therefore, the focus of this study was to determine if there is an effect of parasites on the dietary availability of total mercury (THg) within piscivorous pinniped hosts. THg concentrations ([THg]) in selected host tissues, parasites, and GI lumen contents from 22 California sea lions (Zalophus californianus), 15 ringed seals (Phoca hispida), and 4 spotted seals (Phoca largha) were determined. Among all pinnipeds, [THg] in acanthocephalans of the large intestine were significantly higher than concentrations in other samples (host lumen contents, other parasites and host intestinal wall), irrespective of location within the host GI tract. δ N values of parasites depended both on parasite group and location within the GI tract. δ N values were consistently higher in parasites inhabiting the large intestine, compared to elsewhere in the GI tract, for both sea lions and seals. δ C values in parasites did not differ significantly from host GI tissues. Based on both [THg] and stable isotope values, parasites are likely affecting the Hg bioavailability within the GI lumen contents and host tissues, and toxicant-parasite interactions appear to depend on both parasitic taxon as well as their location within the host intestine.
