摘要
目的了解广东沿海海域海产品中重金属污染状况和食用安全性。方法2007年4—8月采集广东沿海海域17个海区及2个海鲜批发市场海产品,采用电感耦合等离子体质谱法同时测定海产品中5种元素[铅(Pb)、镉(Cd)、铬(Cr)、铜(Cu)及锌(Zn)]含量,采用单因子污染评价模式对金属含量进行污染评价,根据无公害食品水产品有毒有害物质标准限量对海产品的食用安全性进行评估。结果广东沿海海域鱼类中5种重金属含量均低于国家无公害标准,而贝类等软体动物中重金属含量相对较高。牡蛎中Zn及Cu含量最高,出现污染超标现象;栉孔扇贝及牡蛎中Cd含量超过无公害标准;除方斑东风螺的Cr含量超过无公害标准,贝类中Cr及Pb含量均低于无公害标准。结论广东沿海海域鱼类5种重金属安全卫生质量较好,贝类中重金属含量大于鱼类,出现一定的超标现象。
Objective To investigate the content of heavy metals in the seafood from sea areas of Guangdong province and assess the seafood safety. Methods The seafood samples were collected from seventeen representative sea areas and two seafood markets in Guangdong province from April to August 2007. The contents of Cu, Zn, Cr, Cd and Pb were measured by ICP-MS. Single factor contamination estimation in seafood was conducted and the sea food safety was assessed. Results The contents of five heavy metals in fish were below the standard limits for harmless fishery food, and the contents of heavy metals in shellfish were higher than those of fish. The contents of Cu and Zn in some oysters were higher than the evaluation standard of heavy metal pollution for the marine animals. The contents of Cd in chlamys farreri and oysters were higher than the standard limits of harmless fishery food. Except the higher content of Cr in babylonia areolata, the contents of Cr and Pb in shellfish were below the standard limits. Conclusion As for the levels of heavy metals, Cu, Zn, Cr, Cd and Pb, in the fish from the sea areas of Guangdong province is safe for health and but the levels of the five heavy metals exceeded the safety limits in varying degrees in some shellfish.
