A Preliminary Evaluation of the Lethal and Sub-lethal Toxicities to Fish of Effluents from Diamond Exploration in the Lac de Gras Area (DFO, November 1995)
This independent toxicity assessment evaluates the lethal and sub-lethal effects of kimberlite effluents from diamond exploration activities in the Lac de Gras region on freshwater fish species (lake whitefish, lake trout, and rainbow trout), and identifies toxic components including high pH, suspended solids, and various metals such as aluminum, iron, and nickel.
