摘要：
In order to investigate the distributions and characters of sixteen (U.S. EPA) polycyclic aromatic hydrocarbons (PAHs) in PK10, samples were collected from three districts in Jinan, P.R. China during 2004-2005 and 2008-2009. The total concentrations of 16 PAHs were 33.6-627.3 ng.m(-3) in 2004-2005 and 37.4-696.0 ng.m(-3) in 2008-2009. Annual variations were slight. A small increase of PAR level presented from 2004-2005 to 2008-2009, while four and five aromatic rings accounted for 70% of all PAHs. An obvious seasonal trend of PAH abundance was observed. The highest concentrations of PAHs were measured in winter. Benzo(k)fluoranthene (BkF, 4-ring) and fluoranthene (FluA, 5-ring) were the most abundant PAHs in winter. Spatial variations of PAHs were obviously impacted by local pollution sources. In non-heating seasons, the district had more industries and traffic presented the most PAHs; in heating seasons, the district that had higher population density appeared more contamination for the domestic heating.
