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 will compare mercury bioavailability and bioaccumulation patterns in Lake Champlain basins across seasons from our field research. We will also discuss the implications of these patterns for fish consumption risks, including unique risks to subsistence anglers.
