The variation pattern and emission sources were analyzed. The average concentration of total VOCs observed was 41.3×10-9, which showed a descending order of alkane>aromatic hydrocarbon>alkene>alkyne. Source analysis of VOCs by PMF showed that the LPG emission>aged VOC>gasoline vapor>petrochemical industry, unknown source emission>gasoline vehicle emission>solvent use source>diesel vehicle emission>biogenic emission. The sources related to vehicle emission and industrial activities accounted for 46.8% and 21.0% of total VOCs respectively, it showed control measures to vehicle and industry should be strengthened. %R %U http://www.hjjkyyj.com/hjjkyyj/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
