摘    要:文章评述了气溶胶中多环芳烃污染源类型识别的几种方法,即:比值法、轮廓图法、特征化合物法和多元统计方法等.比值法简单可行,应用较多,但常因苯并(a)芘的不稳定性而带来误差,建议与轮廓图法、特征化合物法等配合使用,多元统计法要求样品数多,并且运算复杂,目前应用尚不多见,但其潜力很大。

关 键 词:气溶胶  污染源  芳香族烃

Abstract:The four methods--Ratiomethod, Profile method,Indicator method and Multivariate statistical analysis method for identification of PAH of sources have been reviewed.Ratio method is used widely due to its efficacy and simplicity; but it may cause error because some PAHs are unstable. It is suggested to use Ratio method with Profile and Indicator methods. Multivariate statistical analysis method needs a large number of samples and is very complicated. There are only few reports about its application to identify the sources of PAH in aerosol; but it has strong potency.
Keywords:Aerosol  PAH  Pollution Sources  Identification
