Nutrient enrichment in the Peace, Athabasca and Slave Rivers : assessment of present conditions and future trends / by P.A. Chambers.: R71-49/4-4E-PDF

"The aim of this report was to address the Northern River Basins Study (NRBS) question: “Are the substances added to the rivers by natural and manmade discharges likely to cause deterioration of the water quality?” In this report, the word “substances” was taken to mean nutrients or, more specifically, nitrogen and phosphorus. Other NRBS reports have addressed the impact of effluent loading from the perspective of contaminants. This report synthesizes results from research and monitoring studies undertaken as part of the NRBS to characterize nutrient loading from all point and diffuse sources in the Northern River basins, evaluate the impacts of nutrient loading on river chemistry, assess the response of riverine biota to nutrient loading from pulp mill and municipal effluents in situ, quantify nutrient responses of benthic biota, and investigate interactions between nutrients and contaminants in pulp mill effluent on food webs. These findings are used to assess the state of aquatic ecosystem health, and develop scientific and management recommendations for the Northern River basins"--Summary.
