The formation kinetics and mechanism of O3 and SOA from different AHs are still unclear. Thus the photochemical oxidation mechanism of nine AHs with NO2 is studied. Increased formation rate and yield of O3 and SOA are observed via promoting AH content. Raising the number of AH substituents enhances O3 formation but decreases SOA yield, which is promoted by increasing the methyl group number of AHs. Results help show conversion of AHs to secondary pollutants in the real atmospheric environment.
