研究了乳山湾6～9月间贝类体内Cu、Zn、Pb、Cd、Cr、As、Hg等重金属含量富集水平，结果表明，贝类体内以Cu、Zn含量最高，特别是牡蛎体内Cu含量在8月中旬高达69．09mg／kg·ww，较其他重金属含量高得多，反应了该湾受Cu污染较严重，但均未超过海洋生物体内有关软体双壳类的污染评价标准。 The concentrations of Cu, Zn, Pb, Cd, Cr, As, Hg and other heavy metals in shellfish from September to September in Rushan Bay were studied. The results showed that the content of Cu and Zn in shellfish was the highest, especially in the oyster The content was as high as 69.09 mg / kg · ww in mid-August, which was much higher than other heavy metals, which reflected that the bay was seriously polluted by Cu. However, it did not exceed the evaluation standard of molluscs of marine bivalve molluscs.
