英文摘要	PM10 samples from a garden site (site A), an industrial-traffic intersection (site B), a residential site (site C) and an island site (site D) were collected at December 21-29, 2004; March 18-22, 2005; July 4-13, 2005 and October 24-28, 2005 in Xiamen. 15 priority PAHs compounds were analyzed by using a gas chromatograph/mass spectrometer (GUMS). The abundance and origin of 3 PAHs are discussed to reveal seasonal variations in Xiamen air quality. Average concentrations of Sigma 15PAHs were 17.5 ng/m(3), 3.7 ng/m(3), 32.6 ng/m(3) and 10.5 ng/m(3) from spring to winter with the highest value in autumn. The dominant PAHs components in every season were low and middle molecular weight PAHs including phenanthrene, pyrene, fluoranthene and chrysene. Diagnostic ratios and PCA analysis identified the main sources of particle bound PAHs: mainly from both gasoline and diesel vehicles exhaust, with some contribution from coal combustion, industry emission and cooking sources.
