| 摘要: |
| 对淮安市某垃圾填埋场土壤中１３个采样点中典型重金属Ｃｒ、Ｐｂ、Ａｓ、Ｈｇ、Ｃｄ、Ｃｕ、Ｚｎ的含量进行了调查，采用单因
子污染指数、综合污染指数及Ｈａｋａｎｓｏｎ潜在生态风险指数法评价了土壤中典型重金属对其所在环境的污染程度，对周围
环境造成的潜在生态风险影响。结果表明，研究区域内重金属含量均未超过《土壤环境质量标准》（ＧＢ１５６１８－１９９５）二
级标准。主要的潜在生态风险因子为Ａｓ，潜在生态风险因子大小顺序为Ａｓ＞Ｈｇ＞Ｃｄ＞Ｃｕ＞Ｃｒ＞Ｐｂ＞Ｚｎ。 |

| Abstract: |
| The situation and distribution of heavy metal pollution were investigated in the soil of the Municipal landfill in Huaian, Through analyzing the contents of the typical heavy metal pollutants (Cr,Pb,As,Hg,Cd,Cu,Zn) in the soil of 13 sample sites. The potential influences around environment involving the heavy metals were evaluated by the ecological risk index of Hakason ecological risk, single factor contamination index and comprehensive contamination index. The results showed that none of heavy metal in the studied region had overrun the Grade II of national Environmental Quality Standard for Soil (GB 15618-95).The major factor of potential ecological risk was As, and the order of the potential ecological risks was As>Hg>Cd>Cu>Cr>Pb>Zn. |
