Natural Source Contaminants in the Yukon: Focus on Selenium

This report is a product of the continuation of a study begun in 2007/08. The 2007/08 report focused on selenium concentrations and pathways in the aquatic ecosystems of various tributaries of the Francis, Finlayson and Pelly rivers, which drain portions of the Yukon Tanana-Terrane and Cassiar Platform between Ross River and Watson Lake. In 2008/09 the sampling program was expanded to another area of the Yukon that is recognized as being highly mineralized: areas within the Selwyn Basin. The 2008/09 study area is located along the North Canol Road, northeast of Ross River.
