摘　　要：通过采集分析济青高速公路两侧土壤样品,对公路两侧土壤重金属污染物砷(As)、镉(Cd)、铬(Cr)、汞(Hg)、铅(Pb)的分布特征进行了研究。研究结果表明,随着与高速公路距离的增大,重金属含量在逐渐降低,且高速公路两侧土壤中重金属均不存在超标现象,表明目前高速公路的运营对其两侧土壤产生了影响,影响相对较小,没有达到污染的级别。This paper studies the distribution feature of the heavy metal contaminants such as As, Cd, Cr, Hg, Pb from soil samples adjacent to both sides of Jinan-Qingdao Expressway. The results show that heavy metals levels gradually go down in the soil along with the distance far away from the freeway. Even though, heavy metals levels attain the standards. Which further indicate that current operation of the expressway impose modest impacts on the expressway surrounding soils, in terms of heavy metal contribution.
