矿山尾砂土壤重金属污染及形态分析

Heavy Metal Pollution and Speciation Analysis for Mine Tailings Soil

通过对矿山周边不同层次土壤采样提取,分析土壤中重金属污染程度及形态,结果表明,在上层土壤中重金属的污染扩散情况较为严重,且多以残渣态为主;根据土壤中重金属污染程度及形态,对矿山尾砂土壤重金属污染治理与防范提出了合理建议。

The soil at different levels around the mine was sampled for analyzing the degree of heavy-metal pollution and the form of pollutant in the soil.The results show that there is more serious contamination and scattering of heavy metals in the upper layer of soil,and the pollutant are mainly in the form of residues.Based on the pollution degree and the form of heavy metal pollutant in the soil,some reasonable suggestions were proposed for the treatment and prevention of heavy metal pollution of sand tailings in the mine.
