摘    要:对河北与京津地区42个样点非采暖期大气中多环芳烃(Polycyclic Aromatic Hydrocarbons,PAHs)的研究表明,该区域大气中的PAHs浓度水平较高.2~3环PAHs主要分布在气相当中,颗粒相(大气可吸入颗粒物,PM10)中PAHs以4~6环为主.PAHs的高浓度样点在石家庄、唐山和邯郸地区分布最为集中.县城样点与城市样点的PM10和PAHs污染水平相近.临近区域广泛存在的大气污染很可能对北京市的大气环境造成影响.

关 键 词:多环芳烃  可吸入颗粒物  非采暖期  河北

Abstract:The distribution of PAHs in the atmosphere at 42 sites located in the Hebei,Beijing and Tianjin areas was investigated.Relatively high levels of PAHs were found at some sites.The 2-and 3-ring species were mostly in the gas phase and the higher ring-Number congeners dominated in the particulate phase(PM10).The sites with the highest PAHs concentrations were mainly located in Shijiazhuang,Tangshan and Handan.Concentrations of PM10 and PAHs from the sites in rural areas were close to the concentrations from sites in bigger cites.The air quality in Beijing may be affected by the ubiquitous air pollution in the adjacent areas.
Keywords:PAHs  PM10  non-heating season  Hebei
