摘　　要：于2008年5月～10月在淮南市采集PM10样品进行GC-MS分析,并探讨了研究区内PM10中16种优控多环芳烃的浓度特征和来源。结果表明:16种多环芳烃总量在36.98～452.49 ng.m-3,BaP浓度在1.46～39.90 ng.m-3。PAHs浓度变化关系为:淮化>谢家集>田十五小>安理大>大通三小。BaP与PAHs浓度呈正相关(R2=0.792)。不同环数多环芳烃的质量浓度为:5环>4环>3环>6环>2环。采用比值法判定淮南非采暖期大气中PAHs主要来源于燃煤和机动车尾气,煤尘、扬尘和石油源也有一定贡献。PM10 samples were collected at five sampling sites in Huainan from May-October, 2008, which were determined by GC-MS. Concentrations and sources of PAHs were illustrated. The results show that PAHs pollution in Huainan was serious. Concentrations of PAHs were 36.98-452.49 ng.m^-3 ,and concentrations of BaP were 1.46-39.90 ng.m^-3. Concentrations relationship of PAHs is： Huaihua〉 Xiejiaji〉Tianshiwuxiao〉AUST〉Da tongsanxiao. BaP and PAHs concentrations were positively correlated （R square =0.792）. Concentrations of PAHs varied with the molecular structure： 5 rings〉4 rings〉 3rings〉6 rings〉2 tings. Based on the ratios of PAHs, we conclude that the pollutants mainly come from coal combustion and vehicle exhaust, and other sources such as coal dust,traffic dust and oil source may also have some contributions.
