| 摘 要： | 对镇江地区表层土壤环境中的镍（Ni）和汞（Hg）进行采样监测，以了解镇江地区土壤环境中重金属Ni和Hg的污染状况与空间分布。结果表明，镇江地区表层土壤环境中Ni含量为20．3～99．8 mg/kg，Hg含量为0．03～0．82 mg/kg，与江苏省土壤环境背景值相比，均有一定程度的富集。从Ni和Hg的来源分析，镇江地区土壤环境污染的一个重要来源是大气降尘污染。

| Abstract: | In order to find the situation of pollution caused by heavy metals of Ni and Hg in the soil and their spa-tial distribution in Zhenjiang region,a large number of samples of surface soil were determined,which showed that the concentration of Ni in the surface soil within the region was 20.3-99.8 mg/Kg,while that of Hg was 0.03-0.82mg/Kg.The determined values of both of the elements were one time higher than the averaged ones in Jiangsu province.It＇s The main source of the polluting heavy metals was most probably caused by dust dropping from the lo-cal atmosphere. |
