Biogeochemistry of Global COntaminants

- Research Group -

We study how biogeochemical processes affect the fate, transport and food-web bioaccumulation of trace metals and organic chemicals in aquatic ecosystems. We develop and apply models at a variety of scales ranging from ecosystems (e.g., the Gulf of Maine, the North Pacific and Arctic Oceans) to global applications to characterize how changes in climate and emissions affect human and ecological health, and the potential impacts of regulatory actions. We measure chemical concentrations and reaction rates in environmental samples (natural waters, sediments and aquatic biota) and humans (hair, blood) to parameterize and evaluate our models.

Featured Paper

This paper assesses the impacts of hydroelectric power expansion in the Canadian North on methylmercury exposures and risks of local indigenous populations.  The analysis is based on field data and community level exposure and dietary information from three Inuit Communities in Labrador, Canada.
