| 摘 要： | 对太湖底北部表层20cm深沉积物样进行了重金属元素含量(Hg、Cd、Pb、Cu、Ni、Cr)分析，采用Hakanson潜在生态危害指数对其生态危害进行了评价：结果表明，沉积物表层5cm深以来Hg、Cd、Ph元素含量增加比较显著，生态危害指数比较高，构成了沉积物中等危害，其原因可能与太湖北部梅梁湾周围大量工业和生活废水未经处理直接排放相关。

| Abstract: | The heavy metal elements (Hg,Cd,Pb,Cu,Ni,Cr)from the external 20cm sediments in the north basal Taihu basin were analyzed,and their potential ecological risks were evaluated by using Hakanson potential risk index.It is demonstrated that since the surficial 5cm depth,the elements of Hg,Cd,Pb increased markedly in content,and so do their ecological risk index,constituting a medium risk in the sediments.It is concluded that the possible reasons of rise are attributed to the direct emission of untreated industrial and residential wastes along Meiliang bay in north Taihu lake. |
