| 摘 要： | 在2005-05-03——05-27期间,用Anderson九级采样器在南京市两个采样点采集大气气溶胶样品,同时进行了部分排放源的采集。用X射线—荧光光谱仪(XRF)分析得到气样及源样中PM10的化学成分,分析了南京市大气气溶胶的元素质量谱分布,进行了PM10的富集因子分析,并应用化学质量平衡法(CMB)计算各类源对气溶胶PM10的贡献。结果表明,各类污染源对南京市气溶胶PM10的贡献率分别为:建筑尘(35.45%)、煤烟尘(22.13%)、土壤尘(20.27%)、硫酸盐(5.43%)、汽车尘(4.61%)、海盐(1.91%)、冶炼尘(1.69%)、其它源(8.51%)。文中还结合了南京市TSP和PM2.5的来源解析结果,分析了南京市不同粒径气溶胶颗粒物的污染特征。

| Abstract: | Atmospheric aerosol particles have been collected by Anderson cascade impact sampler at two sites in Nanjing from May 23 to 27,2005.Several sources have been collected at the same time.All these samples have been analyzed by X-ray fluorescence analysis for elements characteristics.Element mass concentration spectrum distribution has also been analyzed,the enrichment factor of every element in Inhalable Particle(PM10) is calculated,and the chemical mass balance method(CMB) has been applied to identify the sources of aerosol PM10.The result of the source apportionment shows that the major contributions of PM10 aerosol mass in Nanjing include: construction dust(35.45%),coal combustion(22.13%),soil dust(20.27%),sulfate(5.43%),motor vehicle exhausts(4.61%),sea salt(1.91%),steel industry dust(1.69%),and other sources(8.51%).As compared with the source apportionment results on TSP and PM2.5 in Nanjing,the characteristics of atmospheric particulate pollution in Nanjing have also been analyzed in this article. |
