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  206Pb/ 207Pb.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.
Key words:  atmospheric aerosol  lead isotope abundance ratio  air mass back trajectory map
