| 摘 要： | 以沪宁高速公路常州段为研究对象,对公路两侧农田表层土壤(0～20 cm)中的铅、镉、铜、锌含量进行了监测.铅、铜、锌用火焰原子吸收分光光度法测定,镉用石墨炉原子吸收分光光度法测定.用单项污染指数和综合污染指数法对土壤中重金属污染状况进行评价.结果表明,在距离公路150 m的范围内,土壤中铅含量变化范围为16.88～32.05 mg/kg,与当地土壤背景值相比,受到不同程度的铅污染,综合污染指数为1.40,属轻污染.镉、铜含量与当地土壤背景值相比,也受到了不同程度的污染.说明,公路交通产生的铅污染是影响公路两侧农田土壤质量的主要污染物.

| Abstract: | The concentrations of lead,cadmium,zinc and copper in roadside soils along Shanghai-Nanjing highway(Changzhou section)were investigated with atomic absorption spectrophotometry(AAS).The samples were taken from the surface soil(0-20 cm) at different distances from the highway.Lead concentrations in the soil samples 150 m from the highway varied from 16.88 mg/kg to 32.05 mg/kg.Compared to the background,the soils were contaminated considerably by lead from the highway traffic.It can be concluded that Pb pollu... |
