摘要
研究了湖南省郴县东坡铅锌矿自然扩散晕内重金属的污染特征及污染控制措施，结果表明，该区域内的环境污染是以Ｐｂ、Ｚｎ、Ｃｄ和Ａｓ为主的多金属复合污染，污染物在土壤中的化学形态以残渣态为主，水体中的细微尾矿砂颗粒物是重金属的主要迁移载体。该区域内作物中的Ｐｂ、Ｃｄ残留很高。
The characteristics of heavy metal pollution and its controlling measures in lead zinc mine area of South Hunan province were studied. The results showed that the environmental problem in mine area is Pb, Zn, Cd and As related multi metal pollution. The major chemical form of heavy metal in polluted soils was found to be in residual fractions. Fine grained ore tailing particles is the major carrier for transportation of heavy metals. The contaminations of Pb, Cd in crops of mine area were very serious. Altering of cropping systems is an effective measure for controlling of heavy metal pollutions in lead zinc mine area.
