摘要
以粤北乐昌铅锌矿区水道（包括铅锌矿废水排泄沟、霜降河段及武江段）底泥为研究对象，通过野外采样和室内分析，分析了底泥中重金属含量，对其污染特征进行评价。结果表明：重金属在各采样点含量均超过清洁对照点；底泥重金属内梅罗综合污染指数范围是为2．25-60．5，平均为35，综合评价等级为Ⅳ级，属于重度污染。
Based on sampling and anatyzing me heavy the watercourse of Lechang Lead-Zinc mine area （included the mining wastewater canal, Shuangjiang River reach and Wuiiang River reach）, the pollution characters have been evaluated. The results have shown that the concentrations of heavy metals were much higher than that at clean sites, the Nemerow comprehensive pollution index by heavy metals in the watercourse sediment were between 2.25-60.5 with an average of 35 and the pollution level as IV, belongs to the heavy pollution.
