摘　　要：本文利用ICP-MS等技术分析了湘中地区黑色页岩及其相应土壤的重金属含量,在对分析结果进行统计分析的基础上,探讨了黑色页岩与土壤重金属污染的关系。研究表明,黑色页岩是富集多种重金属元素的特殊岩石。以黑色页岩岩系为母岩的土壤,不仅明显富集Cu、Cd、Cr、Co、Pb、Zn、Mo、Ni、V、U、Sn、Sb、Tl、Th等多种重金属元素,而且受到Mo、Sb、Cd、U、Tl、Cu、V、Sn、Th等重金属的污染,其中以Mo、Cd、Sb、U、Tl等的污染尤为严重。黑色页岩土壤重金属污染在一些地方已产生明显的负面环境效应,值得关注。The concentrations of heavy metals in black shale and soils derived from the black shale in central Hunan Province, China, were measured using ICP-MS technique. The relationship between characteristics of the black shale and the heavy metal contaminations of its overlaid soil was investigated in this study. The results showed that the black shale was abundant in heavy metals and the overlaid soil not only enriched with many heavy metals, such as, Cu, CA, Cr, Co, Pb, Zn, Mo, Ni, V, U, Sn, Sb, Tl and Th, but also was contaminated by many toxic heavy metals, such as Mo, Sb, Cd, U, Tl, Cu, V, Sn and Th. This study found that contaminations of Mo, Cd, Sb, U and Tl were very serious in the study area. Negative environmental impacts caused by such heavy metals contaminations had been reported in many areas and demands more attention in the future.
