摘　　要：多环芳烃因强烈的致畸、致癌、致突变作用而引起广泛关注,其成分谱是识别和解析污染源的重要基础。文章收集和整理近年来我国学者在中国排放源颗粒相多环芳烃成份谱方面的主要研究成果,并根据多环芳烃来源进行分类。经归一化处理后,对不同排放源多环芳烃成分谱的整体特征进行分析,结合不同排放源多环芳烃的特征标志物、环数分布以及特征比值,初步得到基于统计意义的成分谱和特征比值,对传统参考值的科学性进行验证,为以后的源解析工作提供重要基础。Widespread public concerns are growing over polycyclic aromatic hydrocarbons （PAHs） pollution which has been deemed to cause carcinogenesis, teratogenesis and mutagenesis. Source profiles of PAHs are critical in identification and recognition of their pollution sources, and based on data from previous studies and our recent studies on the source profile of particle phase PAHs, the overall characteristics of PAHs source profile was analyzed. Furthermore, the initial PAHs source profile and diagnostic ratios of statistical significance were obtained through the discussion of the characteristic factors, ring number distribution and diagnostic ratios of PAHs in different emission sources; in addition, the scientificity of traditional reference values was also vali.dated. It is expected that results of the study would be helpful in the pollution source apportionment.
