利用2000年3月大亚湾环境现状调查的资料,对大亚湾底栖生物体中残毒量进行现状与历史资料比较分析,评价底栖生物受重金属污染的程度及其食用质量。结果表明,该水域底栖生物未受重金属污染,但甲壳动物和软体动物体中Cu和Zn具有潜在的严重积累问题;甲壳动物和软体动物体中Cd含量已超过人体消费标准,应引起有关部门的警惕。
The paper presents the results of analysis and assessment of heavy metal content in the benthons in Daya Bay. The results were obtained as follows. (1) The average content of heavy metal contents in fish is Zn>Cu>Pb>Cd, in crustacea and mollusc is Zn>Cu>Cd>Pb. (2) Benthons have not been polluted by heavy metals, but the concentration of Cu and Zn in crustacea and mollusc has potential serious accumulation problems. (3) The content of Cd in crustacea and mollusc has beyond the human consumption. That should be noticed by the concern department.
