"This report summarizes and reviews British Columbia data for specific contaminants in bivalves (Phylum Mollusca, Class Pelecypoda or Bivalvia). This report concentrates on those contaminants associated with anthropogenic activities and is restricted by the nature of the data to a discussion of heavy metals, PCBs and PAH. Studies conducted in B.C. and elsewhere in the world related to the use of bivalves as indicator organisms and the effects of toxic chemicals on bivalves are reviewed. The review of British Columbia data shows high levels of some contaminants have been reported in some shellfish. These high levels were associated with known pollution sources or spills and did not occur in major commercially or recreationally harvested shellfish areas"--Abstract, page i.
