Dynamic Environment & Ecosystem Health Research (DEEHR) Group

Saint Mary's University, Halifax, Nova Scotia
What the facility does

Food web transfer and cycling of environmental contaminants

Areas of expertise

Mercury and metal contamination is a global issue, especially in aquatic ecosystems. The Dynamic  Environment & Ecosystem Health Research (DEEHR) Group tackles this by examining how mercury and metals become bioavailable, are transferred through ecosystems and accumulate in living things to high concentrations. Understanding those processes will enable people to reduce the harm those contaminants do by efficiently reducing sources and establishing priority regions for future management.
