“…The bioavailability and toxicity of POPs and pesticides in wildlife is likely to increase in response to rising temperatures and salinity (Boone and Bridges, 1999;Capkin et al, 2006;Gaunt and Barker, 2000;Heugens et al, 2001;Moore et al, 2003;Schiedek et al, 2007;Silbergeld, 1973;Song and Brown, 1998;Tachikawa and Sawamura, 1994;Wang et al, 2001;Waring and Moore, 2004). An underlying mechanism of this interactive toxicity is that temperature alters the toxicokinetics of chemical pollutants in exposed biota (Buchwalter et al, 2003;Lydy et al, 1999;Maruya et al, 2005).…”

“…The toxicity of contaminants may be enhanced with increasing temperatures (Boone and Bridges, 1999;Capkin et al, 2006;Gaunt and Barker, 2000;Silbergeld, 1973). While the exact mechanisms underlying this relationship are not fully understood and the majority of research focuses on aquatic species, studies indicate that temperature-induced shifts in metabolism are one controlling factor (Buckman et al, 2007;Lydy et al, 1999;Monserrat and Bianchini, 1995).…”

Climate change induced by anthropogenic warming of the earth's atmosphere is a daunting problem. This review examines one of the consequences of climate change that has only recently attracted attention: namely, the effects of climate change on the environmental distribution and toxicity of chemical pollutants. A review was undertaken of the scientific literature (original research articles, reviews, government and intergovernmental reports) focusing on the interactions of toxicants with the environmental parameters, temperature, precipitation, and salinity, as altered by climate change. Three broad classes of chemical toxicants of global significance were the focus: air pollutants, persistent organic pollutants (POPs), including some organochlorine pesticides, and other classes of pesticides. Generally, increases in temperature will enhance the toxicity of contaminants and increase concentrations of tropospheric ozone regionally, but will also likely increase rates of chemical degradation. While further research is needed, climate change coupled with air pollutant exposures may have potentially serious adverse consequences for human health in urban and polluted regions. Climate change producing alterations in: food webs, lipid dynamics, ice and snow melt, and organic carbon cycling could result in increased POP levels in water, soil, and biota. There is also compelling evidence that increasing temperatures could be deleterious to pollutant-exposed wildlife. For example, elevated water temperatures may alter the biotransformation of contaminants to more bioactive metabolites and impair homeostasis. The complex interactions between climate change and pollutants may be particularly problematic for species living at the edge of their physiological tolerance range where acclimation capacity may be limited. In addition to temperature increases, regional precipitation patterns are projected to be altered with climate change. Regions subject to decreases in precipitation may experience enhanced volatilization of POPs and pesticides to the atmosphere. Reduced precipitation will also increase air pollution in urbanized regions resulting in negative health effects, which may be exacerbated by temperature increases. Regions subject to increased precipitation will have lower levels of air pollution, but will likely experience enhanced surface deposition of airborne POPs and increased run-off of pesticides. Moreover, increases in the intensity and frequency of storm events linked to climate change could lead to more severe episodes of chemical contamination of water bodies and surrounding watersheds. Changes in salinity may affect aquatic organisms as an independent stressor as well as by altering the bioavailability and in some instances increasing the toxicity of chemicals. A paramount issue will be to identify species and populations especially vulnerable to climate-pollutant interactions, in the context of the many other physical, chemical, and biological stressors that will be altered with climate change. Moreover, it w...

“…The AEM functional group is capable of forming hydrogen bonds with molecules containing hydrogen-donor and acceptor groups [37] and presents more opportunities for bonding; thus accounting for greater ES sorption affinity compared to the CEM. AEM sorption of ES would be facilitated through bonding between the S-1 (S=O, C-7) and C-10 (C-O) hydrogen-acceptor groups and the AEM CH 3 hydrogen-donor group, while bonding between ES diol and the AEM would be between the C-7 and C-10 OH groups. However, the AEM quaternary ammonium group is dissociated and the cation may be strongly hydrated.…”

Endosulfan (ES) is a micropollutant found in reverse osmosis concentrates from water reuse applications. Electrodialysis (ED) can remove and recover charged solutes from such concentrates.While polar compounds cannot normally be removed, their fate in ED is important as they can contribute to membrane fouling/poisoning and be released during cleaning. High adsorption of ES to ED membranes was observed. Consequently, the influence of solution pH and presence of humic acid (HA) on sorption mechanisms of ES to ion-exchange membranes during batch sorption isotherm and ED experiments were investigated systematically. ES-membrane partition coefficients * Current address: Faculty of Engineering, University of Wollongong, Wollongong NSW 2522, Australia 2 (log K AEM/CEM ) quantified through sorption isotherm experiments suggested that ES sorption was resultant of membrane catalysed ES degradation, hydrogen bonding and cation-π interactions between ES and membrane functional groups. ES sorption at pH 7 (550 µg/cm 3 ) was greater than sorption at pH 11 (306 µg/cm 3 ) due to alkaline hydrolysed ES and resultant decrease in bonding capacity with the membranes at high pH. The presence of HA reduced sorption at pH 7 (471 µg/cm 3 ) and 11 (307 µg/cm 3 ) due to HA competitive sorption. Partial membrane desorption was noted in isotherm (≤ 20%) desorption experiments and was dependent on the initial mass sorbed, solvent pH and resultant membrane interactions.
