Concentrations of Metals in Fishes from the Athabasca and Slave Rivers of Northern Canada
Abstract There is growing concern about possible effects of exploitation of the Alberta Oil Sands on the ambient environment, including possible effects on populations of fishes in the Athabasca River and farther downstream in Lake Athabasca and the Slave River. In the present study, concentrations...
