摘    要:对内蒙古鄂尔多斯地区4个公路段土壤中的重金属元素(Pb、Cd、Cr、Cu、Hg、Zn、Ni)和类金属(As、Se)污染特征进行研究。结果表明:4个公路段都存在不同程度的土壤重金属污染,相对污染程度最低的东胜段公路而言,树林召段公路土壤中铬(Cr)存在显著性污染,棋盘井段公路土壤中汞(Hg)存在显著性污染,薛家湾段公路土壤中铬(Cr)和类金属砷(As)存在显著性污染。通过分析发现,虽然机动车辆的尾气排放能够造成公路土壤中的重金属污染,但是此次调查的4个公路段土壤中的重金属污染来源主要是机动车辆运载煤时的煤尘飘落以及当地的工业排废。所以应该以加强对运煤车辆管理和工业污染源的控制为着力点,治理和降低公路绿化及公路旁耕地中重金属污染。

关 键 词:公路土壤  重金属污染  机动车辆  工业排废  鄂尔多斯

Abstract:Through characteristics analysis of the heavy metals(Pb,Cd,Cu,Hg,Cr,Zn,Ni) and metalloid(As,Se) in the soil of four environment cells along the highway.The results showed that there were different heavy mental pollution.The pollution sequence was Qipanjing>Xuejiawan>Shulinzhao>Dongshen.Contrasted with soil of Dongshen there was significant heavy metal pollution of Cr in soil of Shulinzhao,Hg in soil of Qipanjing and Cr and As in soil of Xuejiawan.Scattering of coals during transportation of trucks and industry waste were the main causes of serious pollution in research sites although motor vehicles by themselves could cause heavy mental pollution in soil along highway.So it should strengthen the management of trucks with coals and control of industry pollution sources in order to provide safeguards for virescence of highway and control of heavy mental pollution in soil along highway.
Keywords:Highroad soil  Heavy metal pollution  Motor vehicles  Industry waste  Erdos
