摘  要:
通过对红透山铜尾矿重金属分布及尾矿区和农田区土壤重金属污染状况进行研究,结果显示:尾矿中四种重金属Cu、Zn、Pb、Cd均出现不同程度的淋滤-富集现象,对周围土壤存在较大的环境威胁。尾矿区土壤综合污染指数16.27,达重污染程度;周围农田土壤为轻度污染,综合污染指数1.29。四种重金属的污染状况分别为:Cd、Cu为重度污染,Zn为轻度污染,Pb为安全级别。

摘  要:
The distribution characteristics of heavy metals in mine tailing and heavy metal pollution in mine tailing areas and surrounding cropland areas were studied. The findings indicated that there was distinct enrichment of heavy metals (Cu, Zn, Pb, Cd) in different depths of mine tailing profile,and that was dangerous to surrounding soils. The integrated polluted index of mine tailing soils was 16.27, and the surrounding agricultural soils was polluted lightly(the integrated polluted index was 1.29).The contamination levels of Cu and Cd were classified as heavy and Zn was classified as lightly. The contamination levels of Pb was safely.
