  • 摘要: 通过野外采样及室内分析测试,对宿州市煤矿区周边农田表层土壤及其典型剖面中的Cu、Zn、Cr、Cd、Pb、Hg、As 7种重金属污染特征及其在剖面上的垂向迁移规律进行了研究.结果表明,煤矿区周边500 m内农田表层土壤除Cu、Zn、Pb外,Cr、Cd、Hg、As均超出国家土壤环境质量标准(I级),其中As、Cd轻度污染,Cr中度污染,Hg重度污染;表层土壤重金属含量随着距煤矿的距离增加而呈下降趋势,表明煤炭开采活动对煤矿区周边土壤造成了严重的重金属污染;在土壤剖面上,不同深度土壤中的Cr、Cd、Hg含量均高出邻区泗县,且与土壤深度存在明显的负相关关系.
    Abstract: Based on field sample collection and laboratory analysis, the characteristics of pollution, as well as the vertical migration of the heavy metals including Cu, Zn, Cr, Cd, Pb, Hg and As were investigated. The results indicate that the concentrations of Cr, Cd, Hg and As exceeded the Class I National Soil Environmental Quality Standard. The pollution grade is light for As and Cd, moderate for Cr, and severe for Hg. A negative correlation between the concentrations of heavy metals in surface soil and the distance between coal mine and farmland was revealed, indicating that mining had an important contribution to the heavy metal pollution of farmland around the coal mine. Additionally, the concentrations of Cr, Cd and Hg in soils from different depths are all higher than those of soils in Sixian County adjacent to Suzhou City, and are negatively correlated with the depth of soil.
