Current and historic mining of primarily iron has impacted the water chemistry of the St Louis River and there is concern that the altered water chemistry has impacted the behavior of mercury in the River and resulted in elevated fish mercury levels. This talk will examine recent research done by Gustavus students on bioaccumulation and cycling of mercury in the River and the freshwater estuary between the St Louis River and Lake Superior.
