| 摘 要： | 文章分析了湘江衡阳段28个站点的表层沉积物中的重金属(Cd、Pb、Cu、As、Cr、Zn)总量和空间分布特征。参照国内相关标准和背景值,运用相关性分析与地累积指数分析法对检测结果进行重金属污染程度的分析评价。结果表明:湘江衡阳段表层沉积物各重金属的污染程度排序为:Cd>Pb>Zn>Cu>As>Cr,湘江衡阳段沉积物存在严重的重金属污染,其中位于水口山工业区的中游水域沉积物污染最为严重。

| Abstract: | Concentrations and distribution of heavy metals(Cd,Pb,Cu,As,Cr,Zn) in the surface sediments of 28 sites included in Hengyang section of Xiang River were investigated.Based on domestic relevant standards and background,the methods of correlation analysis and geoaccumulation index analysis were used to assess the pollutant.The results shows that order of pollution level of heavy metal was Cd>Pb>Zn>Cu>As>Cr.The pollution of heavy metal in the surface sediment in Hengyang section of Xiang River was in a high le... |
