Research Webinar: Winter Mercury Patterns in Lake Champlain and Future Environmental Health Risks

Scientists have studied mercury cycling in lakes for decades. However, mercury bioavailability and transfer through the food chain during the winter is understudied compared to other seasons despite its potential sensitivity to climate change and importance to environmental health risks. This seminar compared mercury bioavailability and bioaccumulation patterns in Lake Champlain basins across seasons from the team's field research. They also discussed the implications of these patterns for fish consumption risks, including unique risks to subsistence anglers.    

This webinar is part of the Lake Champlain Sea Grant Research Seminar Series; it took place on November 16, 2022.
