Chemical contaminants in Canadian aquatic ecosystems
This report focuses on those chemicals that persist in the Canadian environment and that are accumulated by aquatic organisms. It summarizes scientific information collected previously, with emphasis on Canadian research findings published in the last decade. The first part of the report introduces the general features of aquatic ecosystems and provides basic information on the fate and effects of chemical contaminants. The second part reviews contaminant related issues for the following geographic areas: Atlantic marine ecosystems including the St. Lawrence, Bay of Fundy, and general north-west Atlantic; freshwater ecosystems including the Great Lakes and inland waters; the Arctic marine ecosystem; and Pacific aquatic ecosystems including the British Columbia coastal ecosystem, the open coast, and some of the major rivers. All chapters discuss the major contaminant issues, important oceanographic or limnological features, biological resources, and sources of contaminants as well as contaminant trends, distribution, and effects. Current and emerging chemical contaminant issues and associated research topics are summarized at the end of each chapter. The third part is an overall assessment of current knowledge of chemical contaminants and their effects on fish and fish habitat, and identifies major current and emerging contaminant issues confronting Canada`s fish and fish habitat.
