| 摘 要： | 不同公路两侧土壤重金属Cr、Ni、Cu、Zn、As、Cd、Hg、Pb含量同对照区差异较大 ,但Cu、Pb均为污染区大于对照区。蔬菜重金属Cr、Ni、Cu、Zn、As、Cd、Hg、Pb含量在不同蔬菜品种表现出不同特征 ,大葱、莴笋大部分重金属含量高于对照区 ,甘蓝大部分重金属含量低于对照区。不同公路两侧土壤和蔬菜重金属含量差异明显。两公路土壤和莴笋重金属Pb含量表现出一致性 ,因此公路边重金属累积较重的元素主要为Pb

| Abstract: | The contents of heavy metals such as Cr,Ni,Cu,Zn,As,Cd,Hg,Pb in soils have more big difference between besides the roads and the comparison areas in different roads, but the contents of Cu,Pb in polluted areas are higher than in the comparing areas. It displays the different characteristic that the contents of heavy metals in different vegetable breeds, and the contents of major heavy metals in onion and lettuce are higher than in the comparing areas, while the contents of wild cabbage are lower than in the comparing areas. There have obvious differences between the contents of heavy metal in soils and vegetables of different besides the roads. The contents of heavy metals of Pb in soils and lettuces in the two roads have concordance. So the heavy metal of high accumulated is Pb beside the road. |
