摘要
文章系统研究了宝鸡市街尘中铅的含量水平,结果表明:宝鸡市街尘中铅的含量为140.60~1864.60mg/kg,平均值408.41mg/kg,为宝鸡市土壤环境背景值的19.1倍,污染现状较严重。地累积指数法和铅污染指数法的评价结果表明:宝鸡市街尘中铅污染整体上处于偏重污染水平;其中,加油站和火车站附近的交通干道上,其铅含量分别达到1864.60mg/kg和1138.40mg/kg,是宝鸡市铅污染最为严重的区域。
Content of lead in urban street dust of Baoji City Shanxi Province is studied systematically. The range of lead content in street dust of urban is 140.60~1864.60mg/kg,with average value of 408.41mg/kg,which is 19.1 times of the soil lead background value of the City .The assessment results show that the lead pollution in urban street dust is generally at relatively serious pollution level, and the content of lead in urban dust from gas station and railway station is highest, reaching 1864.60mg/kg and 1138.40 mg/kg respectively.
