다국어 초록 (Multilingual Abstract)

This study was performed to investigate the contamination level of harmful heavy metals in 11 species shellfish collected at the four sampling sites of the western coast in Korea from June to November in 1996. The levels of total lead, cadmium, mercury, copper and zinc were determined and the results were summarized as follows (ppm) : The minimum and maximum values of shellfish, mean value bracketed, were ; Pb : 0.07-7.42(3.09), Cd : 0.015-0.573(0.08), Hg : 0.44-1.93(0.69), Cu : 2.88-112.68(19.46), Zn : 50.79-578.90(124.84). The results show that mean contents of Pb, Cd, and Hg in 11 species shellfish were not yet dangerous levels enough to pose a health problem. But the contents of Pb, Hg, Cu and Zn has a increasing tendency.
