| 摘 要： | 测试和研究了舟山本岛8条河流沉积物中Cu、Zn、Pb、Cd、Hg、As、Cr的含量与分布特征,利用地累积指数法和Hakanson潜在生态风险指数法对沉积物重金属进行了生态风险评价,结果表明:(1)基于地累积指数法的评价表明Hg、Cr、As为清洁,Cu、Pb、Cd、Zn为轻度污染;(2)基于单项潜在生态风险系数的评价表明研究区内沉积物中Cu、Pb、As、Zn、Cr处于轻微等级,Cd和Hg则有不同程度的污染;该区域重金属生态风险等级顺序为Cd>Hg>Cu>Pb>As>Cr>Zn;(3)根据综合潜在生态风险指数,城关河和展茅河处于中等风险等级。

| Abstract: | Based on the analysis,a comprehensive assessment on heavy metals in the sediments was presented using index of geo-accumulation and Hakanson potential ecological risks index.The results indicate that,based on the geo-accumulation index,Hg、Cr and As belong to"clean",Cu、Pb、Cd and Zn belong to"mild pollution".Based on the single heavy metal ecological risk index,the risk levels of Cu、Pb、As 、Zn and Cr belong to"slight"level,The risk order of the heavy metals is Cd> Hg>Cu>Pb>As>Cr>Zn.According to the Hakanson potential ecological risk index,City River and Zhanmao River is of the middle level. |
