摘要
采用恒能量同步荧光法检测了龙岩市大气颗粒物(PM_(10))样品中PAHs(多环芳烃)的质量浓度,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.结果表明燃煤污染和汽车尾气排放是龙岩市大气颗粒物多环芳烃污染最主要的来源.
The composition of polycyclic aromatic hydrocarbons （PAHs） in fly ash samples collected from different districts in Longyan city was analyzed using constant-energy synchronous fluorescence spectrometry technique. The differences of the contents of PAHs in fly ash samples were compared. The variations of the PAHs of different seasons were discussed. The PAHs distribution and contamination sources were analyzed. The results showed that coal combustion and vehicle emission were the predominant sources for particulate PAHs in Longyan.
