矿区煤矸石山周围土壤重金属分布规律研究

THE HEAVY METALS STUDY OF THE GANGUE HILL MINING AREA AROUND THE DISTRIBUTION

对某矿区矸石山及周围土壤五种重金属(Cr、Cd、Cu、Pb、Zn)总量进行测定,结果显示,两个矿区矸石中五种重金属含量均高于当地背景值,同时受矸石山影响,矸石山周围土壤重金属含量也都不同程度地超出背景值,即重金属对土壤产生不同程度的污染。数据分析结果表明,矸石山周围土壤中的重金属平面与剖面分布具有一定的规律特征:土壤重金属含量的大小与土壤距离矸石山的远近有关;同时重金属的分布受气候及其它影响而呈现了一定的波动性特征。

Based on sampling and testing heavy metals pollution characteristic of the gangue and the soil surrounding the gangue hill,we found that:the distribution of five heavy metals(Cd、Cr、Cu、Pb、Zn) in soil surrounding the gangue hill varies with the distance between the soil and the gangue hill.The content of the heavy metal in the soil decreases with the distance away from the gangue hill.On the profile,the content of heavy metal gradually decreases with depth.The local direction of the wind also influenced the d...
