Short summary
This study examines the transformation of organosulfates through reaction with HO• radicals. The results show that the nature of substituents on the carbon chain can effectively affect the decomposition rate of organosulfates, and ozone is unveiled as a complementary oxidant in the intermediate steps of this decomposition. The primary products from these reactions include carbonyl compounds and inorganic sulfate, which highlights the role of organosulfates in altering aerosol chemical composition.
