Aquatic and terrestrial organic matter in the diet of stream consumers: implications for mercury bioaccumulation.
The relative contribution of aquatic vs. terrestrial organic matter to the diet of consumers in fluvial environments and its effects on bioaccumulation of contaminants such as mercury (Hg) remain poorly understood. We used stable isotopes of carbon and nitrogen in a gradient approach (consumer isotope ratio vs. periphyton isotope ratio) across temperate streams that range in their pH to assess ...
متن کاملUse of terrestrial field studies in the derivation of bioaccumulation potential of chemicals.
Field-based studies are an essential component of research addressing the behavior of organic chemicals, and a unique line of evidence that can be used to assess bioaccumulation potential in chemical registration programs and aid in development of associated laboratory and modeling efforts. To aid scientific and regulatory discourse on the application of terrestrial field data in this manner, t...
متن کاملA terrestrial food-chain bioaccumulation model for POPs.
Mechanistic bioaccumulation models for fish and piscivorous food-webs are widely used to assess the environmental hazard and risk of commercial chemicals, develop water quality criteria and remediation objectives, and conduct exposure assessment of pesticides in aquatic systems. Similar models for mammals and terrestrial food-webs are largely absent. As a result, the hazards and risks of bioacc...
متن کاملAn arctic terrestrial food-chain bioaccumulation model for persistent organic pollutants.
A model representing the bioaccumulation of persistent organic pollutants (POPs) in arctic terrestrial mammalian food-chains is developed, parametrized, tested, and analyzed. The model predicts concentrations of POPs in lichen, caribou (Rangifer tarandus), and wolf (Canis lupus) food-chains of Canada's central and western arctic region from measured concentrations in air and snowpack meltwater....
متن کاملBioaccumulation of Dioxins in Terrestrial Food Chain: Concentrations of Dioxin Congeners and Trophic Level
Polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and nonand mono-ortho-substituted polychlorinated biphenyls (dioxin-like PCBs) was analyzed in earthworms, plants, insects, field mouse and birds collected in Kanagawa Prefecture and their accumulation in the terrestrial ecosystem was studied. TEQ was highest in raptor species and followed by mouse liver, other bir...
