Concentrations of trace elements and radionuclides in four fish species from the Black Lake area of northern Saskatchewan
Future expansion of uranium mines in northern Saskatchewan, as well as the presence of the small abandoned Nisto uranium mine on the north shore of Black Lake, have raised concerns over potential contaminants in fish consumed by local residents. This report presents results of analyses of six fish caught in Black Lake and Stony Lake by local residents and analyzed for radionuclides and trace elements. For comparison, a rainbow trout raised on a British Columbia fish farm was also analyzed. Food chain transfer of radionuclides and other elements was estimated by using concentrations in gastrointestinal tract samples to represent the food source of the fish. Elements analyzed include uranium, radium-226, lead-210, calcium, potassium, mercury, and chromium.
