| 摘 要： | 受上游铅锌矿区尾砂坝坍塌的影响，大环江沿岸土壤重金属污染严重。通过对研究区4个采样点24个土壤样品进行分析，结果表明，土壤中As、Pb、Cd、Zn4种重金属严重超标，其中As、Cd、Zn含量有从中游到下游递减的趋势。垂直剖面分析结果表明，土壤重金属污染主要集中在0～17cm以内的土壤表层和耕作层；运用相关系数进行分析，发现土壤中存在着明显的As、Pb、Cd、zn复合污染带。

| Abstract: | Due to the collapse of the tailing dam in the Pb / Zn mine on the upstream of Huanjiang river,soils along the riversides has been seriously contaminated.Twenty-four soil samples were collected from four locations and analyzed.The results showed that the contents of four heavy metals(As,Pb,Cd,Zn) in the soil were seriously higher than the standard.The contents of As,Cd and Zn showed diminishing trends from the middle river to the lower river.The analysis of the ver-tical section in the soil indicated that th... |
