| 摘 要： | 通过对鲁西南煤炭基地若干混堆的煤矸石山周围(10～100m)耕作层土壤的实际调查及分析测试资料,研究了煤矸石堆附近耕作层土壤中重金属污染状况。结果表明,土壤局部已经受到Cd、Ni的污染,但未出现多金属复合污染状况。煤矸石堆附近土壤已经受到采矿等人类活动的影响,其中Cd、Hg的人为影响最大。从8种重金属元素含量随深度的变化曲线形态来看,Hg、Cd 2种元素与Cr、Ni、Cu、Zn、Pb、As6种元素曲线形态显示差异性,Hg、Cd元素在土壤中赋存、迁移等应具特殊性,有待进一步研究。

| Abstract: | Based on the practical investigation and analysis test results in surface soil around （10-100m） in coal-production base of Shandong Southwest, pollution of heavy metals in sur- face soil around coal gangue dumps was researched. The results show that, surface soil have been polluted, Soil Environmental Quality Standard （GB15618-1995） as the soil quality as- sessment standard, by Cd or Ni in local region, but no apparent combined pollution. Heavy metals content of surface soil have been affected by mining and human activity, which Cd, Hg is big. Element content Curve shape with depth displays difference between Hg, Cd and Cr, Ni, Cu, Zn, Pb, As. |
