两类典型重金属土壤污染研究

Study on two kinds of heavy metals pollution of soils

对贵州水城矿务局周围煤矸石污染土壤和Pb、Zn冶炼场污染土壤的重金属污染状况进行了研究和评估 .研究结果表明 :煤矸石风化形成的土壤有一定的重金属污染 ,污染程度取决于煤矸石的组成 .Pb、Zn土法冶炼造成土地严重污染 ,在污染土壤上种植的农作物中重金属含量严重超标 .重金属在土豆不同部位富集程度各不相同 ,而且Pb Cd、Pb Zn、Zn

Heavy metals in soils contaminated by coal spoil and smelter in Shuicheng city, Guizhou province, were investigated. The result indicatd that the content of heavy metal in coal mine spoil is an important factor for the degree of contamination of soils. Heavy metals in different crops growing in contaminated soils by smelter seriously exceeds the national standard. Distribution of heavy metals in potato was leaves + stems> roots> tubers, and there were positive relationships between lead, cadmium, zinc.
