摘 要: | 对珠江流域红水河上游河水29个样点重金属元素含量进行分析,采用单因子指数法和内梅罗指数法对其重金属污染程度进行评价。结果表明,红水河上游河水中重金属Pb的含量为2.15~19.7μg/L,Cd的含量为0~5.12μg/L,Cr的含量为0.52~1.6μg/L,Cu的含量为3.55~12.2μg/L。3个采样河段Cd的单因子污染指数>1.0,说明Cd超标;支流1和主流上游河段内梅罗指数>1.0,为轻度污染;支流2内梅罗指数<1.0,为污染警戒。

Abstract: | The heavy metal content in twenty-nine sampling sites in the upstream of Honghe River of Pearl River Basin was analyzed.The single-factor index method and Nemerow index were adopted to evaluate the heavy metal pollution degree.The results showed that the contents of Pb,Cd,Cr and Cu were 2.15-19.7,0-5.12,0.52-1.6 and 3.55-12.2 μg/L.The single pollution index of Cd >1.0,indicating exceed the standard;Nemerow index of branch 1 and upstream>1.0,indicating light pollution;Nemerow index of branch 2<1.0,indicating pollution alert boundary. |
