摘　　要：[目的]评价黄渤海区域养殖扇贝产品重金属污染情况,为扇贝养殖的安全生产以及扇贝产品的质量控制提供科学依据。[方法]采用电感耦合等离子体原子发射光谱对黄渤海不同养殖海域扇贝体内锌、铅、镉、铁、铜、锰、铝、铬含量进行了测定,以《无公害食品水产品中有毒有害物质限量》及《海洋生物质量》等卫生要求进行比较,进行黄渤海区域养殖扇贝重金属污染的评价。[结果]试验表明,14种样品中铅含量均不超过0.5 mg/kg,未超过国家标准,且3号、6号样品中铅含量均低于0.1 mg/kg;铜含量均不超过50 mg/kg,未超过国家标准;14种样品中镉的含量均超过0.5 mg/kg,其中11号扇贝镉含量最高,超过国家标准9倍。进行比较后得出,黄渤海区域内扇贝重金属含量大多符合我国相关标准。[结论]各海域扇贝中铅、铜含量均未超过国家相关标准,镉含量均超过国家相关标准,部分海域扇贝中铬含量超过国家标准。Objective] The aim was to evaluate heavy metal pollution in the cultured scallop in the Yellow Sea and the Bohai Sea , to provide scientific basis for safety production and quality control of scallop.[Method] Concentrations of several heavy metals including zinc, lead, cad-mium, ferrum, copper, manganese, aluminum and chromium in the cultured scallop from different districts of the Yellow Sea and the Bohai Sea were analyzed by inductively-coupled-plasma-atomic-emission-spectrum（ICP-AES）.The results were compared to sanitary requirement of Marin Biological Quality and Limited Dose of Harmful Substance in Pollution-free Food and Aquatic Products, thus the levels of heavy metals in the cultured scallop were evaluated.[Result] The results showed that among 14 samples, the lead content was under 0.5 mg/kg, contents in sample No.3 and No.6 were less than 0.1 mg/kg, copper content was under 50 mg/kg, all lower than national standards.While cadmium content in all 14 samples were more than 0.5 mg/kg, among which sample No.11 was 9 times higher than national standards.Through com-parison, the levels of heavy metals in the cultured scallop mostly meet sanitary requirement.[Conclusion] Lead and copper content in the cul-tured scallop are below the limits, while cadmium is above, and chromium in some region exceeds the standard.
