Research is ongoing on the environmental, forensic and analytical chemistry of established (“legacy”) and emerging organic contaminants in wildlife and fish and their aquatic ecosystems. Bioaccumulation, fate, trophodynamics, and spatial and temporal trends are also studied on established and emerging contaminants and metabolites in wildlife (e.g., top predators), food webs, and aquatic ecosystems (e.g., Arctic and Great Lakes). Activities also include mechanistic and comparative biotransformation and pharmaco( toxico)kinetics of contaminants in wildlife and fish. Finally, research is ongoing on species- and ecosystem-specific ecotoxicology and effects of contaminant and metabolite exposure (e.g., endocrine disruption) and assessments.
