| 摘 要： | 通过系统采集高皇和上窑两个贮灰场周围土壤样品,采用ICP-AES分析方法,调查土壤中若干金属元素(Cd、Cr、Cu、Mn、Ni、Pb、Zn)含量,评价淮南市三大热电厂大体积粉煤灰长期处置导致土壤金属污染状况。结果表明:这些元素在土壤中表现积累性富集,Cu、Cd、Cr具有相对高的迁移性。但土壤金属含量除Cu外,均没有超过国家土壤一级质量标准,土壤属无污染或轻微污染类型。因此,有效处置管理措施能够控制淮南粉煤灰中有害金属的环境影响。 |

| Abstract: | An investigation was conducted to assess metal contamination in soils around two coal ash disposal sites(i.e.Gaohuang and Shangyao ash ponds) for three thermal power plants in Huainan energy-based city.Metals(Cd,Cr,Cu,Mn,Ni,Pb,and Zn) in 39 top soil samples were analyzed according to a couple technique(ICP-AES).The results showed that these metals were distributed mainly around the ash disposal ponds and Cu,Cd,and Cr had relatively higher mobility.Soil quality assessment indicated that metal concentrations in the soils except for Cu were less than the national one-level standard of soil quality,and there was no or slight contamination by these metals in the soils surrounding coal ash ponds.. |
