The role of photo-induced solution reactions in determining atmospheric aerosol concentrations is discussed and is investigated with theoretical estimates. The main photo-induced solution reaction considered is the conversion of dissolved O/sub 3/ into H/sub 2/O/sub 2/ which can then react with dissolved SO/sub 2/ and NO/sub 2/ to form sulfate and nitrate. The rate of this reaction is compared to the rate of H/sub 2/O/sub 2/ gas to the aerosol surface. The influences of H/sub 2/O/sub 2/ concentration and aerosol size on the relative rates are investigated. It is found that the photo-induced solution reaction rate is much lower than the gas diffusion rate but becomes more competitive as particle size increases. 9 references, 3 figures, 1 table.
