| 摘 要： | 江苏省某城市由于规划发展的需要,陆续搬迁了一批高污染的化工企业。调查发现其中一家化工厂原厂址存在严重的重金属污染问题,现采集多个表层土壤样品,对样品中的多种重金属(Pb,Cu,Cr,Ni,Zn和Cd)的总量进行分析测试,发现搬迁区土壤重金属累积效应显著,除Zn和Ni外,其它重金属平均含量均超过其背景值,其中Cd的含量是其背景值的324倍,Pb是背景值的1.8倍。重金属的富集顺序为PbCrZnCdCuNi。 |

| Abstract: | This study take a city in Jiangsu Province as an example. The city just relocated a batch of highly poUutionchemical enterprises. The survey found that the original site of a chemical factory has serious heavy metal pollutions. The surface soil samples were collected to test thetotal amounts for heavy metals ofPb, Cu, Cr, Ni, Zn and Cd）. It is found that the heavy metal accumulation effect in these relocation sites is significant, except for Zn and Ni. The average content of other heavy metals excee- ded the background values. The content of Cd is 324 times of the background value, Pb is 1.8 times higher than background val- ue. Heavy metal enrichment in a descending order isPb 〉 Cr 〉 Zn 〉 Cd 〉 Cu 〉 Ni. |
| Keywords: | enterprise relocation heavy metals in soil distribution highly contaminated sites ecological risk assessment |
