摘    要:通过对广州市老城区空气中多环芳烃的研究表明 ,该区多环芳烃的污染相当严重 ,不同季节测定的多环芳烃总量差别不大 ,但颗粒相多环芳烃在春季占的比例 (44 8% )要高于夏季 (9 4 % ) .气相中主要以芴、菲、甲基菲、荧蒽、芘等低环数的多环芳烃为主 ,而高于四环的多环芳烃主要是分布在颗粒相中 ,苯并 (ghi)是最主要的颗粒相多环芳烃物质 .

关 键 词:多环芳烃  气溶胶  相分配

Abstract:The distribution of polycyclic aromatic hydrocarbons (PAHs) in the atmosphere of Guangzhou was investigated. The results showed that little change was observed in the total PAH concentrations between spring and summer. The particle phase contribution ranged from 9.4% of the total PAHs in summer to 44.8% in spring. Fluorene, phenanthrene and their methylated derivatives, fluoranthene and pyrene are the dominant PAH species in the gas phase, while higher ring species PAHs dominated in the particulate phase with benzo(ghi)perylene as the maxima.
Keywords:polycyclic aromatic hydrocarbons (PAHs)  aerosol  phase partitioning
