Concentrations of cadmium, copper and zinc were determined in three molluscan species including Sacculosiphonaria japonica, Reishia clavigera and Crassostrea gigas to assess heavy metal contamination in the Onsan Bay. The range of cadmium concentrations were 3.83¡­39.67 §¶/g d.w. in S. japonica, 7.47¡­103.47 §¶/g d.w. in R. clavigera, 1.32¡­92.17 §¶/g d.w. in C. gigas. Concentration of cadmium at contaminated site in C. gigas was 70 folds higher than that of reference site. The range of copper concentrations were 22.92¡­1287.56 §¶/g d.w. in S. japonica, 37.53¡­656.97 §¶/g d.w. in R. clavigera, 161.50¡­3208.52 §¶/g d.w. in C. gigas. The concentration of copper at contaminated site in S. japonica was 56 folds higher than that of reference site. The range of zinc concentrations were 93.48¡­377.40 §¶/g d.w. in S. japonica, 423.65¡­1075.57 §¶/g w. in R. clavigera, 2018.13¡­22275.00 §¶/g d.w. in C. gigas. The difference of zinc concentrations between reference site and contaminated site was relatively small than those of cadmium and copper in all the species tested. The largest difference was 11 folds in C. gigas. In the present work, we confirmed that all of these species, S. japonica, R. clavigera and C. gigas, could be used as biological indicators to monitor heavy metal contamination.
