| 摘 要： | 研究贵州SS、SQ典型铅锌矿区土壤的环境质量,在SS、SQ铅锌矿区采集土壤样品共15个,利用F-640、AA800等仪器测其土壤中7种重金属元素的含量,采用单因子污染指数法和N.L.Nemerow综合污染指数法对研究区域重金属污染进行分析,结果表明,矿区土壤中重金属污染程度有较大差异,Cu、As、Cr等3种重金属元素无或轻污染;Cd、Zn、Hg、Pb等4种重金属元素对该区土壤环境已造成污染;SS、SQ土壤中重金属综合污染相当严重。

| Abstract: | A total 15 soil samples from Pb,Zn ore field in SS and SQ of Guizhou were collected to assess environmental quality there.Seven kinds of heavy metal content in the soil were measured by F-640 and AA800.Heavy metal pollution was analyzed by single-factor pollution index and NLNemerow integrated pollution index.The results indicated that various differences existed in heavy metal contamination in soils of the mining areas.Cu,As and Cr generated little pollution,while Cd,Zn,Hg and Pb caused pollution.Heavy metal pollution in SS and SQ mining soils was quite serious. |
