The interactive kinetic chemistry of oxidized sulfur and other trace gases has been examined in computations for the suburban New Jersey troposphere. The results of several calculations studying alternate chemical pathways for sulfoxy compounds suggest that ozone concentrations are not greatly sensitive to the chemistry of SO2 and its products. The latter are, however, shown to be slight inhibitors to ozone production, under both normal and reduced levels of reactive hydrocarbons. The computed minimum generation rate of sulfate aerosol is ~1 &mgr;g/m3 day, largely through sulfuric acid deposition on aerosols.
