某铀矿山尾矿坝周边水土的重金属迁移规律研究
摘要
对某铀矿山尾矿坝周边不同水平距离的水体和土壤剖面的pH值及重金属元素Cu
Ni
Cd
Pb
Zn进行测试分析
结果表明:pH值越低就越能促进重金属溶出
向活性形态转化;重金属污染与水平距离成反比
污染进程由近及远;与垂直深度成正比
有累积沉淀现象。
Abstract
PH value and contents of heavy metals(Cu
Ni
Cd
Pb
Zn)in surrounding different soil sections and water of a uranium mining tailings dam were analyzed.The results show that low pH value can promote dissolution of heavy metal and can enhance its activity.And heavy metal pollution is inversely proportional to the horizontal distance and directly proportional to the vertical depth.
