The study led by Erin Kelly and David Schindler of the University of Alberta also found that levels of the pollutants cadmium, copper, lead, mercury, nickel, silver and zinc exceeded federal and provincial guidelines for the protection of aquatic life in melted snow or water collected near or downstream from oilsands mining.”
