摘要：
The electron-excited chemistry of sulfur dioxide oxidation induced by UV irradiation of air with trace O-3 and SO2 is considered. The importance of this mechanism is evaluated based on recent laboratory experiments on SO2 oxidation in a laminar tube with air induced by UV irradiation. Results show that under respective conditions the route of SO2 oxidation involving electron excited oxygen molecules may present an additional source of gaseous H2SO4 production to known OH-radical mechanism.
