Earthworms as a source of mercury in terrestrial food chains

Project Overview
Research Core Areas: 
Project Abstract: 
Several studies of methyl mercury have shown bioaccumulation occurs in aquatic systems, and ends up increasing in quantity further up the food chain. Fewer studies have been performed on terrestrial wildlife, or looked into how mercury might be building up in food chains not associated with aquatic systems. Earthworms have been shown to be able methylate mercury, and soil studies performed across the continental US has shown mercury levels to be rather high across the Upper Peninsula (UP) in Michigan. Thus, the project investigates mercury levels in earthworms across the UP and attempts to determine correlations between the mercury levels in the American marten within the same areas.
