| 摘 要： | 为了解贵州典型铅锌矿区土壤中重金属的污染及生态危害情况,以贵州典型铅锌矿区水城的XQ、SS采样点和都匀的DA、QS采样点土壤中的重金属含量为研究对象,采用N.L.Nemerow综合污染指数法和Lars Hakanson潜在生态危害指数法,研究矿区土壤中重金属的分布情况、污染特征及生态危害。结果表明,以土壤环境质量标准和矿区周边耕地土壤的重金属平均含量为参比值,DA矿区重金属污染最严重,生态危害最严重;各采样点综合污染指数和生态危害指数大小顺序为:DA>QS>XQ>SS。结论:所研究的矿区土壤质量不适合种植农作物,对人体健康有潜在危害。

| Abstract: | In order to know the heavy metal pollution and its ecological risk in the soil of typical lead and zinc mining areas in Guizhou Province,the concentration of heavy metals in DA,QS,XQ and SS minning areas in Guizhou were chosen to research.N.L.Nemerow comprehensive pollution index method and Lars Hakanson potential ecological risk index method were adopted to research the distribution,the pollution features and the ecological risk of the heavy metals in the soils in the mining areas.The results showed that DA mining area was the most seriously polluted mine with the most serious ecological pollution,based on the reference indexes of soil environment quality standard and the average concentration of the heavy metals in the cultivated land around the mining areas.The comprehensive pollution index and ecological risk of the sampling spots were in the order DA>QS>XQ>SS.It is not suitable to grow crops in the mining areas which would do potential harm to health. |
