In situ organic aerosol formation during a smog episode estimated production and chemical functionality

In situ organic aerosol formation during a smog episode estimated production and chemical functionality

Atmospheric Environment Part A General Topics 26(6): 953-963

Estimates are presented of the amount and chemical functionality of the organic aerosol formed in situ in the atmosphere during a smog episode. Input parameters used in these estimates include speciated volatile organic carbone (VOC) emission rates, their rates of reaction, the corresponding reaction products including condensible species, and the nature and yields of these condensible species. The functional groups predicted to form and the estimated amount produced during a typical smog episode are carbonyls, aliphatic nitrates, aliphatic carboxylic acids, phenols and nitro aromatics (670, 240, 1360, 3120 and 3120 kg day-1, respectively, using southernn California VOC emission data as an examle of application). Similarities and differences between calculated organic aerosol composition and experimental observations (two data sets obtained using different methods) are discussed in terms of organic aerosol formation pathways and sampling artifact for the following functional groups: alphatic carboxylic acids, carbonyls, aliphatic nitrates, phenols, aromatic acids, nitro aromatics, amides and esters.
