| 摘 要： | 为全面了解长寿湖底泥沉积物中重金属含量及其潜在生态危害程度,采用Hakanson潜在生态风险指数法对长寿湖流域各采样点典型重金属污染物Cd、Cr、Cu、Pb和Zn的潜在生态风险进行评价。结果表明,长寿湖区域沉积物5种重金属单因子污染程度顺序为：Cd〉Cu〉Pb〉Zn〉Cr。从综合污染程度分析,各种重金属的污染潜在生态风...

| Abstract: | Through analyzing the contents of the typical heavy metal pollutants(Cd,Cr,Cu,Pb and Zn) in the sediments of 6 sampling sites from the Changshou Lake catchment,this paper used the indexing techniques of single factor and Hakanson ecological risk to quantitatively determine the extent of pollution and the potential ecological risks of heavy metals in the sediments of Changshou Lake.The results showed that the main factor leading to heavy metal pollution was Cd.The pollution degrees of heavy metals in the sed... |
