Trace metals in marine organisms from coastal waters of southern British Columbia (1971 to 1976) / by R.M. Harbo, I.K. Birtwell, and O.E. Langer. : Fs97-4/1691E-PDF

"Trace metal concentrations were determined in a variety of marine organisms from southern coastal waters of British Columbia. This report lists data for samples collected between 1971 and 1973, and in 1976 from waters adjacent to urban and industrial areas. The levels of mercury, copper, zinc, lead, cadmium, nickel, arsenic and iron in tissue samples have been summarized for selected edible molluscs, crustaceans and fishes. Results are expressed on a dry and wet weight basis. Spiny dogfish, Squalus acanthias, had the highest mercury content of 1.01 ± 0.47 µg g⁻¹ (wet weight). Pacific oysters, Crassostrea gigas, had a high mean zinc level of 647 ± 927 µg g⁻¹ (wet weight). The concentration of cadmium in C. gigas was also much higher than that found in other shellfish; 1.37 ± 0.50 µg g⁻¹ (wet weight)"--Abstract, page iv.
