| 摘 要： | 通过对莫愁湖底泥中铜(Cu)、铅(Pb)、锌(Zn)、铬(Cr)、镉(Cd)5种重金属元素的含量分析,并运用地累积指数法和潜在生态风险指数法对其污染程度和潜在生态风险进行评价.结果表明,5种重金属中,只有Pb为无-中度污染,其余4种均未构成污染;莫愁湖底泥中重金属污染的潜在生态风险表现为极轻微的程度,生态风险顺序是:Cd>Pb>Cu>Cr>Zn.

| Abstract: | In this paper, the sediments of Mochou Lake were sampled and analyzed for the contents of 5 kinds of heavy metals (Cu, Pb, Zn, Cr and Cd) and evaluated by the Index of Geoaccumulation and the Index of the Potential Ecological Rick. The results showed that the Pollution by Pb was 0-1 degree while that of the other 4 were free of pollution. Generally, Mochou Lake was exposed to a light potential ecological risk, the degree ranked as follows: Cd>Pb>Cu>Cr>Zn. |
