摘　　要：对大亚湾底栖生物重金属含量进行调查与分析 ,评价底栖生物重金属污染程度及食用质量 .结果表明 ,该水域底栖生物体内重金属平均含量顺序为 :Zn >Cu >Pb >Cd ;底栖生物未受重金属污染 ,但甲壳动物和软体动物对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的重金属Cd含量已超过人体消费标准 。The heavy metal contents in benthons in the Daya Bay are analyzed and assessed. The results show that: (1) The average contents of heavy metal in benthons are Zn>Cu>Pb>Cd;(2) Benthons have not been polluted by heavy metals, but the concentration of Cu and Zn in crustacea and mollusc is potentially serious;(3) The content of Cd in crustacea and mollusc is beyond the standard for human consumption,and that should be noticed by departments concerned.
