摘　　要：采用恒能量同步荧光法检测了龙岩市大气颗粒物样品中的多环芳烃(PAHs),比较了龙岩市区大气颗粒物中多环芳烃含量的差异以及不同季节对多环芳烃含量的影响,讨论了其分布规律及污染源。The composition of polycyclic aromatic hydrocarbons（PAHs） in fly ash samples which were gathered from every district of Longyan City were analyzed using constant-energy synchronous fluorescence spectrometry technique.The differences of the contents of PAHs in fly ash samples from every district were compared.The changes of the PAHs of different seasons were discussed.Finally we analyzed the distribution of PAHs in Longyan and the sources of contamination.

关 键 词：多环芳烃 恒能量同步荧光 大气颗粒物
