| 摘 要： | 分析研究了宁通公路、204国道两条主要公路两侧农田土壤Pb、Cr、Ni、Zn、Cd含量分布特征、影响范围及其差异，并对公路旁农田土壤重金属累积程度、潜在生态危害进行了评价。结果发现，同一公路不同路段土壤重金属累积含量程度不同；两条公路两侧土壤重金属含量累积程度不高，潜在综合生态危害程度都很低，以轻微危害为主；而由汽车轮胎摩擦产生的Cd在公路两侧农田土壤中累积程度最高，为最主要的污染重金属；不同等级的公路两侧土壤重金属累积范围存在差异，宁通公路为0m-50m，204国道为0m-30m。

| Abstract: | A survey research on heavy metals Pb, Cr, Zn, Ni, Cd in farmland soils along the main roads and a risk assessment of the soil environment were carried out. The result showed that heavy metals in different road sections were accumulated at different levels. The contents of most heavy metals in the farmland soils along two roads were a bit higher than those in the soil background and its potential ecological risk was low. But Cd in the farmland soil of some road sections was accumulated at a higher level than other heavy metals. Heavy metals in the studied two roads were accumulated at different levels. The maximum contents of heavy metals were found in the samples located in 50m far from roadbed along Nanjing to Nantong highway, and the maximum contents of heavy metals were found in the samples located in 30m from roadbed along national highway 204. |
