| 摘 要： | 采集了河南省平顶山煤矿塌陷区复垦地5个点位的土壤样品,采用HCl-HNO3-HF-HClO4全分解的方法对土壤样品进行处理,用原子吸收分光光度法测定了镉、铅、铜、锌、镍和总铬的含量,根据内梅罗指数法对土壤重金属污染进行了评价,同时对塌陷地和附近正常农田土壤中重金属元素的含量也进行了分析测定.结果表明,复垦土壤的镉、铜和锌含量高于对照土壤,重金属垂直分布无确定规律.复垦土壤大部分样点的总铬和镉的污染分指数大于1.0,发生了不同程度的污染;铅、铜、锌和镍的污染分指数小于1.0,未发生污染.复垦土壤的重金属综合污染指数均大于1.0,发生轻度至重度污染.对照样也发生了不同程度的污染,但污染程度小于复垦土壤."挖深垫浅式"复垦土壤的最大污染因子是镉,"充填式"复垦土壤和对照土壤的最大污染因子是铬.随着"挖深垫浅式"复垦时间的增长,土壤污染程度有减轻的趋势.

| Abstract: | Heavy metal pollution in reclaimed soil in Pingdingshan coal mine was investigated. Soil samples of 5 sites were collected and treated with HCl-HNO3-HF-HClO4, then the contents of Pb, Cd, Cu, Zn, Ni and Cr were determined by atomic absorption spectrophotometry, heavy metal pollution in soil was evaluated with Nemero Index, and the contents of heavy metals in subsided land and normal cultivated soil were also determined. The results showed that the content of such heavy metals as Cr, Cu and Zn in reclaimed s... |
