为研究南京冬季大气颗粒物中PAHs来源情况，利用FA?3型气溶胶采样器从2007年11月20日到12月30日在南京郊区分昼夜采集气溶胶样品，并用GC?MS对16种优控PAHs浓度进行定量分析，采用PCA法对其来源进行解析。结果表明，南京冬季细颗粒物中PAHs浓度明显高于粗颗粒物中PAHs浓度，单种类PAH浓度表现出昼夜差异，日间低分子量PAHs含量高于夜间，而夜间高分子量PAHs浓度则相对较高；主成分分析对PAHs源解析结果表明，南京北郊大气颗粒物中PAHs主要来源为机动车尾气、燃煤源、焦化源、天然气燃烧和烹调源等，粗细颗粒物中PAHs排放源差异明显，细颗粒物部分表现出明显的昼夜差异，同时，外来源和不确定源占有较大比重。
In order to understand the source apportionment of polycyclic aromatic hydrocarbons in fine and coarse particulate matter during winter in Nanjing, PM10 samples were collected from Nov. 20 to Dec. 30, 2007 in northern suburbs of Nanjing by FA?3 sampler, and sixteen PAHs were measured both at day and night using GC?MS. The results show that the concentration of PAHs in fine particles was significantly higher than in coarse particles, and the concentration of individual PAHs have a large difference between day and night. The concentration of low?molecular?weight ( LMW ) PAHs are higher at daytime, but high?molecular?weight ( HMW ) PAHs are higher at nighttime. The result of Principal Component Analysis( PCA) show that the main sources of PAHs are vehicles, coal combustion, pyrogenation, natural gas and coking during winter in northern suburbs of Nanjing, and there are differences between PAHs in coarse and fine particles. The sources of PAHs in fine particles have differences between day and night, and the uncertain sources and external sources take large part of the total sources of PAHs.
