Many studies have monitored atmospheric particulates and gaseous phases of PM(2.5) in Asia over the past 10 years. This work also compared and discussed different sample collection, pretreatment and analytical methods in Asia countries in past decade. The results indicated that the main PM(2.5) sources are traffic exhausts. PM(2.5) concentrations are also ranked highest in the areas of traffic, followed by the urban sites, and lowest in rural sites in Asian countries. This work elucidates the sources, analytical tools, and the average concentrations for PM(2.5) and related metallic elements during 1995-2005. The results indicated that the average highest concentrations order of metallic elements for PM(2.5) were Fe>Mg>Zn, and the average concentrations of lowest metallic elements was Pb>Cu>Mn>Cr>Cd. The results also indicated that the concentration of metallic element Cu increased as the averaged concentrations of metallic element Zn and Mn increased during the past 10 years in Asian countries.
在过去十年中，许多研究对亚洲地区的大气颗粒物及PM2.5的气相成分进行了监测。这项工作还对过去十年亚洲各国不同的样本采集、预处理及分析方法进行了比较和讨论。结果表明，PM2.5的主要来源是交通尾气。在亚洲国家，交通区域的PM2.5浓度也最高，其次是城市地区，农村地区最低。这项工作阐明了1995年至2005年期间PM2.5及其相关金属元素的来源、分析工具以及平均浓度。结果表明，PM2.5中金属元素平均最高浓度顺序为Fe>Mg>Zn，金属元素平均最低浓度为Pb>Cu>Mn>Cr>Cd。结果还表明，在过去十年中，亚洲国家金属元素Cu的浓度随着金属元素Zn和Mn平均浓度的增加而增加。
