| Research Abstract |
Oxygenated organic aerosol(OOA) observed in remote areas is believed to comprise aged secondary organic aerosol(SOA); however, the reaction processes relevant to SOA chemical aging have hitherto been unclear. We analyzed SOA particles formed from the photooxidation of aromatic hydrocarbons using an Aerosol mass spectrometry, liquid chromatography/mass spectrometry, and iodometric spectrophotometry. These results indicate that SOA aging proceeds mainly by formation of carboxylic acids, and that the rate of SOA aging in laboratory chambers is limited by the oxidation of ketone groups.
