Outline of Final Research Achievements

In order to elucidate formation mechanism of 2-methyltetrol (2MT) which is the molecular maker of isoprene secondary organic aerosol, we investigated the effects of RH and particle acidity on 2MT formation conducting a series of the laboratory chamber experiments on isoprene/NOx photooxidtaion. The existence of water was critical for 2MT formation, and 2MT formation was catalyzed by both acid and base. These results suggest that 2MT is produced by the hydrolysis of the esters formed from isoprene/NOx photooxidation. We also studied the rate of 2MT formation in the aqueous solution of the isoprene secondary aerosol formed under dry conditions. It was shown that 2MT can be produced within a time scale of 1 day in the aqueous solution of isoprene aerosol under acidic conditions.
