Wang M. Shao mshao@pku.edu.cn Y. Zhang Y. Wei M. Hu S. Guo State Joint Key laboratory of Environmental Simulation and Pollution Control, College of Environmental Sciences and Engineering, Peking University, Beijing, 100871, China Fine particles (PM_2.5, i.e., particles with an aerodynamic diameter of &le;2.5 &mu;m) were collected from the air in August 2006, August–September 2006, and January–February 2007, in Beijing, China. Particulate organic matter in the ambient samples was quantified by gas chromatography/mass spectrometry. The dominant compounds identified in summertime were <i>n</i>-alkanoic acids, followed by dicarboxylic acids and sugars, while sugars became the most abundant species in winter, followed by polycyclic aromatic hydrocarbons, <i>n</i>-alkanes, and <i>n</i>-alkanoic acids. The contributions of seven emission sources (i.e., gasoline/diesel vehicles, coal burning, wood/straw burning, cooking, and vegetative detritus) to particulate organic matter in PM_2.5 were estimated using a chemical mass balance receptor model. The model runs the present seasonal trends regarding the contributions of various sources to organic aerosols. Biomass burning (straw and wood) had the highest contribution in winter, followed by coal burning, vehicle exhaust, and cooking. The contribution of cooking was the highest in summer, followed by vehicle exhaust and biomass burning, while coal smoke showed only a minor contribution to ambient organic carbon.
