| 摘 要： | 采集湘江(株洲段)9个断面的底泥样品,和1个柱状样品,对重金属(Cu、Pb、Zn、Cd、Ni、Cr、Hg、As)含量进行了检测;并运用地质积累指数法对底泥中重金属进行了生态风险评价.结果表明,该江段底泥已受到较严重的重金属污染,在霞湾断面达峰值.Cu、Pb、Zn、Cd含量为湘江背景值4.6倍~58.8倍,比该江段20世...

| Abstract: | Heavy metals(Cu,Pb,Zn,Cd,Ni,Cr,Hg,As) were detected in the samples which were collected in nine cross sections and one vertical section at Xiangjiang River of Zhuzhou.Ecological risk was evaluated by index of geoaccumulation method.The results showed that sediment of Zhuzhou section had polluted seriously and pollutant concentration at Xiawan was the highest among all samples.The concentrations of Cd,Pb,Zn and Cd reached 4.6~58.8 times higher than background values of Xiangjiang river,and 1.71~1.96 times hi... |
