摘要: 对长春市区环境空气总悬浮微粒(TSP)中Pb的来源进行了研究. 结果表明, 环境空 气TSP中94.8%的Pb来源于汽车尾气. 对长春市区主要交通干线环境空气TSP中Pb的含量进行 测试, 结果表明, 无铅汽油使用后长春市区环境空气TSP中Pb的含量有了较大程度的下降 , 但测试结果与预测结果之间存在着一定差异.

关键词: 铅, 无铅汽油, 汽车尾气

Abstract: After studing the plumbum orgin in Total Suspended Particulates(TSP) of the ambient air of Changchun urban district, the results show that 94.8% of plumbum in TSP of the ambient air come from the vehicle exhaust. The forecasted and tested plumbum contents in TSP of the ambient air of the main t raffic line after using lead-free gasoline show that after using lead-free gasoline, there is a great decline of plumbum content in TSP of the ambient ai r and a difference between the two results.

Key words: plumbum, lead-free gasoline, vehicle exhaust
