"This report describes sediment and biota quality in the St-Clair River, identified by the International Joint Commission as an ‘Area of Concern’ due to habitat, water, and sediment quality issues. Elevated levels of mercury and other contaminants in the sediment and subsequent detrimental effects on the benthic biota have been identified in parts of the St. Clair River. As part of the GL2020 Action Plan, site assessments in the St. Clair River were made using BEAST (Benthic Assessment of Sediment) methodology. BEAST methodology involves the assessment of sediment quality based on a multivariate technique using data on benthic invertebrate communities, the functional responses of laboratory organisms in sediment toxicity tests, and the physical and chemical attributes of the sediment and overlying water. Data from test sites are compared to biological criteria developed for the St. Clair River and Laurentian Great Lakes (revised BEAST model), The bioavailability of sediment mercury and its potential for effects on fish and wildlife through biomagnification was also assessed"--Abstract, p. i.
