The photooxidation of SO2 in irradiated auto exhaust + SO2 systems, the catalytic oxidation of SO2 in the solution droplets of hazes, clouds and fogs containing several concentrations of heavy metals (Mn(+2) and Fe(+3)), and the oxidation of SO2 in irradiated hazes and fogs containing only trace quantities of heavy metals were studied in a 590 cu m indoor smog chamber. For the irradiated auto exhaust + SO2 systems, SO2 oxidation rates as high as 5 percent/hr were observed. Primary particulates from auto exhaust produced no discernible effect on SO2 oxidation. Catalytic oxidation of SO2 in fogs and hazes was significant under certain conditions, with as much as 6 percent of the available SO2 being oxidized in a 30-minute period. No synergistic effect on the rate of SO2 oxidation was observed from the simultaneous presence of irradiation and a fog or haze.
