BIOGEOCHEMISTRY OF GLOBAL CONTAMINANTS

- Research Group -

Our research goal is to better understand how chemicals released by human activity interact with natural ecosystems and affect living systems. A main innovation of our group’s work is to quantitatively analyze the entire exposure pathway for aquatic pollutants to identify key processes that have a large influence on their accumulation in biota. Our research approach combines environmental measurements with statistical and mechanistic simulation models to project chemical levels over space and time. This integrated approach allows us to better understand how global change (both chemical releases and climate change) will affect human and ecological health risks associated with environmental toxicants.

Summary

We developed a new analytical workflow to better understand the concentrations of PFAS precursors present in coastal watersheds of Cape Cod, MA and distinguish the contributions from use of Aqueous Film Forming Foams (AFFF) from other sources. We found large quantities of unidentified organofluorine in Cape Cod coastal watersheds, which warrants further investigation.
