摘要
对204国道江苏段(张家港、常熟、太仓)两侧土壤、大气、植物(树叶、小麦)中的主要重金属(铅、镉、铬、铜、镍、锌)含量进行分析评价,研究结果表明:204国道江苏段两侧土壤已受到重金属污染,其中污染最重的是铬;小麦未受重金属污染;植物(树叶、小麦)中重金属含量与土壤和大气中的重金属含量呈正相关性。
The contents of main heavy metals （Pb,Cd,Cr, Cu, Ni, Zn） in soil, air and plant（leaves and wheat） along the No 204 National road in Jiangsu Province were analyzed and evaluated. The results showed that the soil nearby the No. 204 National road in Jiangsu Province was polluted by heavy metals, the most serious was Cr; wheat was not polluted; the contents of heavy metals in plant were positively correlated with the contents of heavy metals in soil and air.
