摘要
为评价土壤重金属 (铅、镉、汞、砷、铬 )污染 ,选择芜湖市郊区农田进行土壤的采样分析。结果表明土壤环境问题以汞污染最突出 ,铅次之。土壤环境质量基本上未受到镉、砷、铬的影响。汞污染的主要原因 ,可能与当地长期使用含汞农药有关。一些土壤受铅污染的主要原因是汽车尾气所致。

The rdsults showed that primary environmental problem of soil was mercury pollution,the second was lead pollution. The environmental quality of soil wasn't affected by cadmium,arsenic and chromium. The mercury pollution mainly associated with long history of application of pestisides including mercury. The lead pollution was mainly due to diffusion of automobile exhoust gases
