摘　　要：研究了东莞市大气颗粒物上硝基多环芳烃的含量,并优化了样品的前处理过程,采用HPLC-UV定性定量分析了东莞市大气颗粒物上4种硝基多环芳烃的含量,结果发现东莞市颗粒物上硝基多环芳烃的含量显著高于已有报道的其它地区,仅次于广州,其可能的主要来源为汽车尾气的排放,其中3-硝基荧蒽还有其它直接排放源。Concentrations of nitro-polycyclic aromatic hydrocarbons （NPAHs） on total suspended particles in Dongguan City have been reported. The sample pre-treatment process is optimized and qualitative and quantitative analyses of NPAHs are performed by using a High Performance liquid chromatography with UV detection （HPLC-UV）. The resuhs show that the content of 4 NPAHs of atmospheric particles in Dongguan is much higher than in other regions and only second to Guangzhou. The automotive emissions is the main source, but there are other direct emissions source for 3-nitrofluoranthene.
