摘　　要：为了解居民经常食用的水产品重金属污染状况,分析市售水产品的重金属含量,并采用单因子污染指数和金属污染指数法进行评价。结果表明,24种水产品中铅含量为0.0008~0.3422 mg·kg^(-1),铬含量为0.0009~0.2053 mg·kg^(-1),镉含量为0.0004~0.7682 mg·kg^(-1),汞含量为0.0031~0.1072 mg·kg^(-1),无机砷含量为0.0021~0.0538 mg·kg^(-1),5种重金属含量均未超过国家安全标准限量;铬和无机砷属于正常水平,铅、镉、汞元素存在轻度污染;双壳贝类中花蛤对重金属的富集能力最强。In order to understand the heavy metal pollution status of aquatic products commonly consumed by residents,the heavy metal content of aquatic products on the market is analyzed,and the single factor pollution index and metal pollution index method are used to evaluate.The results show that the content of the lead in 24 kinds of aquatic products is 0.0008~0.3422 g·kg^(-1),the content of chromium is 0.0009~0.2053 mg·kg^(-1),and the content of cadmium is 0.0004~0.7682 mg·kg^(-1),the content of mercury is 0.0031~0.1072 mg·kg^(-1),the content of inorganic arsenic is 0.0001~0.0538 mg·kg^(-1),and the content offive heavy metals did not exceed the limited edition of national security standards;chromium and inorganic arsenic are at normal levels,and there are mild pollution in lead,cadmium,and mercury;Paphia undulata has the strongest ability to accumulate heavy metals.
