摘要
以京沪高速公路新沂至扬州段为研究区域,分析了道路两侧土壤、气态颗粒物和树叶中Cd、Co、Cr、Cu、Ni、Pb和Zn等重金属污染之间的相关性。研究结果表明,车流量与表层土壤、表层土壤与气态颗粒物、树叶与表层土壤、树叶与气态颗粒物中重金属污染都有明显的相关性,这种相关性清晰地反映了高速公路两侧重金属的迁移过程。
The section from Xinyi to Yangzhou in Beijing-Shanghai Highway was selected as research objective. The correlation of heavy metal pollution in soil, lithometeor and leaves along both sides of the road were analyzed. The results showed that there were prominent correlation coefficients between vehicle fluxes and soil surface, between soil surface and lithometeor, between soil surface and leaves, between lithometeor and leaves. These correlations clearly reflect the transferring process of the heavy metals around both sides of the Highway.
