| 摘 要： | 采用直接固体进样技术,测定了G107国道两侧不同距离内采集土壤样品的铅含量。结果表明:采用直接固体进样方法,铅的检出限为0.016 ng,样品测试的相对标准偏差为8.6%~10.0%、回收率为84.5%~105.6%;距离G107国道100~1 500 m土壤样品的Pb含量为25.23~35.43 mg/kg。公路主干道两侧土壤铅的主要来源之一为汽车尾气。

| Abstract: | The lead content of farmland soil samples collected from two sides of national road No.107 were determined by direct solid sampling.The results indicated that the detection limit was 0.016 ng,the relative standard deviation was 8.6%-10.0%,and the recovery rate was from 85.1% to 105.6%.The lead contents of soil samples collected from 100-1 500 m to national road No.107 were in the range of 25.23-35.43 mg/kg.The lead was mainly from automobile exhaust. |
