Description: High levels of toxic pollutants in Alberta's Athabasca River system are linked to oilsands mining, researchers at the University of Alberta have found. The findings counter the reports by a joint industry-government panel that the pollutant levels are due to natural sources rather than human development. Mercury, thallium and other pollutants accumulated in higher concentrations in snowpacks and waterways near and downstream from oilsands development than in more remote areas, said the study to published in the Proceedings of the National Academy of Sciences. Upstream and undeveloped sites exposed directly to the McMurray Geologic Formation, the natural source of the oilsands, did not show high levels of pollutants. 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 wate
