Relationship between Concentrations of Copper and Zinc in Water, Sediment, Benthic Invertebrates, and Tissues of White Sucker (Catostomus commersoni) at Metal-Contaminated Sites

The relationship of concentrations of copper (Cu) and zinc (Zn) in white sucker (Catostomus commersoni) tissues to concentrations of those metals in water, sediment, and benthic invertebrates (food) were investigated in a field study. Fish were collected from six northern Ontario lakes contaminated with mixed-metal mining wastes. The concentrations of Cu in invertebrates were correlated with water but not with sediment Cu concentrations. …
