摘要
以株洲市白马乡为研究对象,分别以当地土壤环境背景值和土壤环境质量标准二级标准值为标准评价土壤累积性污染状况和土壤环境质量。结果表明,以两种标准值为标准进行评价的结果和地质累积指标进行检验的结果都出现一定的偏差,表明单以土壤环境背景值或土壤环境质量标准二级标准值为标准评价土壤环境质量可能会出现一些混乱和错误的结论,必须综合各种评价方法进行综合评价。
Four heavy metal pollution （Cd,Hg,As and Pb） in the soils and soil environmental quality were evaluated with the environmental background values of the soils of Baima country, Zhuzhou and Grade H Criterion of GB 15618-1995 as benchmarks. Phenomena were found that evaluation results on basis of two criterion data and verification results by Index of Geoaccumulation were not coincident absolutely, indicating that evaluation by using individual background values or Criterion of GB 15618-1995 would lead to some confused and fault conclusions, so the diversified evaluated methods could used.
