大亚湾经济类海洋生物体的重金属含量分析

Analysis of heavy metal contents in marine organisms from Daya Bay

  • 摘要: 文章讨论了大亚湾主要经济类海洋生物体内重金属含量的变化特征及其富集能力。结果表明,甲壳生物中重金属元素的含量最高、头足类的含量次之、鱼类的含量最低。生物体重金属元素含量从高到低依次为锌(Zn)铜(Cu)铅(Pb) 砷(As)镉(Cd)汞(Hg)。大亚湾海域经济类海洋生物对Cu和Zn的富集能力最高,对As的富集能力最低。大亚湾经济类海洋生物体重金属含量低于无公害食品-水产品有毒有害物质限量标准值。潜在危害系数的计算结果表明,Cd、Pb、Hg存在一定的潜在危害,Cu的潜在危害性很低。

     

    Abstract: The variation feature and biological concentration factors of heavy metal element in commercial marine organisms from Daya Bay were discussed in this paper. It showed that the heavy metal contents in crustacean samples were the highest and the heavy metal contents in fish samples were the lowest among the three kinds of organisms. The order of heavy metal contents in the organisms was zinc (Zn) copper (Cu) lead (Pb) arsenic (As) cadmium (Cd) mercury (Hg). The biological concentration factors of Cu and Zn were higher than the other elements, while the factors of As was the lowest among the elements. The marine organism heavy metal contents were lower than the threshold values of non-environmental pollution food, the limit for the deleterious matters in the aquatic product. According to the result of potential risk factors, there were some potential risk of Cd, Pb and Hg, while the potential risk of Cu was low.
