Title: Source analysis and apportionment of particulate phase polycyclic aromatic hydrocarbons(PAHs) in Guangzhou City
Abstract: Based on the pooled data from a year-round weekly monitoring of PAHs in particulate phase in Luhu Lake, Guangzhou, the source apportionment of PAHs in particulate phases was studied using diagnostic ratios and principal component factor analysis (PCA). The result showed that the predominant sources for particulate phase were vehicle emissions and coal combustion. For total PAHs in particulates, vehicle emissions and coal combustion accounted for 69% and 31%, respectively. Higher concentrations of particulate PAHs in winter were likely due to increased emission from motor vehicle under low temperature driving conditions and to the influence of meteorological parameters such as slower wind speed and lower temperature. However, in summer high concentrations of PAHs were due to the higher emission of coal combustion and slower wind speeds.
