Heavy matals (Pb, Cd, Cu, Zn and Hg) were determined in blue mussel (Mytilus galloprovincialis), short-necked clam (Ruditapes philippinarum) and oyster (Crassostrea gigas) collected from Maizuru Bay, a semi-enclosed marine inlet of the Japan Sea in 2008, in order to elucidate their contamination levels and distribution. The highest Pb concerntrations in blue mussels, short-necked clams and oysters, 9.4±2.4, 229, 8.4±7.1μg/g wet, respectively, were detected in samples from the lead battery recycle factory basin. These three bivalve species can be used as sentimental organisms to moniter Pb contamination in coastal waters. Some evaluates are inferior level applied to the environmental index and food-safety standard. Lead concentrations in blue mussels transplanted to near the factory were increased definitely. In this study, we were able to do comprehensive evaluation by using three kinds of bioindicator.
