摘要
通过近几年重庆市大气气溶胶污染的监测及几种监测方法的比较 ,介绍了重庆大气气溶胶的污染现状 ,推导出TSP手工与自动采样之间、PM1 0 和地面站 β射线法测定结果之间、PM1 0 和 PM2 .5 之间浓度的定量关系。以此 ,计算出大气气溶胶从 1 981年至 1 998年的逐年变化值。
In this paper we present an overview of current air pollution in Chongqing caused by aerosol, with comparing of recent monitoring for aerosol and relevant techniques used in monitoring The quantitative relations between TSP manual measurement and automatic monitoring, PM 10 and its value measured by β ray method in automatic monitoring station, the PM 10 concentration and PM 2 5 concentration are derived Consequently the year to year concentrations from 1981 to 1998 are calculated
