| 摘 要： | 本文对当前大气颗粒物上ＰＡＨｓ的识别和源解析的定量及定性和半定量的方法进行了综述，定性及半定量方法简便易行，但误差大；化学质量平衡法结果较准确具体，但ＰＡＨｓ会发生化学反应而降解，并且没有各种燃烧源较完整的ＰＡＨｓ成份谱，这已成为ＣＭＢ广泛推行的障碍；多元统计方法不考虑ＰＡＨｓ的降解，但要求数据量大，国内外的科学工作者用不同的方法和手段，使ＰＡＨｓ来源的识别和源解析工作有了一定进展。

| Abstract: | The methods for indentification and apportionment of PAHs sources were reviewed in this artical.Qualitative and semiqutitative methods were used widely due to its efficiency and simplicity;but they may cause many errors.The result of chemical mass balance method is more accurately than the former one,but some PAHs can be reactive and unstable,and it is absence of a reliable combustion source fingeprint.Multivariate statistical analysis method needs a large number of samples and is very complicated.With the various way and method,the scientists in home and abroad have been developing the identification and apportionment of PAHs sources. |
