A history of total mercury in edible muscle of fish from lakes in northern Canada.

Subsistence fishing has been an important source of food for Native People in northern Canada since prehistoric time. Measurements of the levels of mercury in edible muscle of northern fish have been undertaken for over three decades in efforts to evaluate the risks of consuming northern fish. This report summarizes the data obtained from 7974 fish of 25 species from sites distributed from the Yukon to Labrador.

Baseline studies in the Slave River, NWT, 1990-1994: Part II. Body burden contaminants in whole fish tissue and livers.

The Northwest Territories section of the Slave River is the recipient of chemical compounds from a variety of sources, including upstream industry and agriculture. In 1990, concerned government agencies formulated a practical, focussed, and comprehensive environmental monitoring program to assess contamination in the river and the Slave River Environmental Quality Monitoring Program was established. The program was designed to respond to the distinct requirements of two major monitoring goals.
