Abstract
Issues surrounding the importance of including heterogeneous processes when determining the fate of oxygenated intermediates in the troposphere are discussed. Results of recent investigations are reviewed and preliminary data from a laboratory study are presented. In the laboratory study heterogeneous processes that determine the fate of oxidation products of irradiated o-xylene/NOX/SO2/air mixtures were investigated. The review includes summaries of (1) the effect of oxidant reactions in cloud water on global photochemistry; (2) the impact of N2O5 and NO3 reactions in cloud water on global photochemistry; (3) the effect of sea salt aerosol reactions in cloud water and tropospheric aerosols; and (4) the impact of transition metal catalyzed reactions of HO2 radicals on tropospheric aerosols.
