| 摘 要： | 对天津市1998年11月-1999年2月期间21个玻璃纤维滤膜大气颗粒物样品,采用稀酸浸出法溶解后,测量了ρ(Pb),w(Pb)和同位素丰度比206Pb/207Pb.采用IDAS软件对样品进行聚类分析,分组的结果表明,在不同的天气条件下,各种污染源排放的贡献也不同.48 h反向风迹图提供了大量详实的气象信息,结合ρ(TSP),ρ(Pb),w(Pb)和同位素丰度比的数据,可用于综合表征铅污染的状况.

| Abstract: | After leaching with diluted nitric acid,21 aerosol samples collected on glassfiber filter in Tianjin from November 1998 to February 1999 were analyzed for ρ(Pb),w(Pb) and isotopic abundance ratio of 206Pb/ 207Pb.Based on hierarchical clustering analysis using IDAS software,21 samples were classified into five groups,which showed that the contributions from various sources are different under different meteorological conditions.The 48 h air mass back trajectory map provided plenty of detailed meteorological information and ,combined with ρ(TSP),ρ(Pb) and w(Pb) as well as lead isotopic abundance ratio,can be used to characterize lead pollution in air. |

| Keywords: | atmospheric aerosol lead isotope abundance ratio air mass back trajectory map |
