Abstract
Purely gas-phase and heterogeneous experiments were conducted to study the influences of atmospheric aerosols on the gas-phase reactions of OH radicals with organic compounds. Three different organics (n-hexane, p-xylene, and 1-propanol) were selected to represent alkanes, aromatics, and oxygenated compounds. Ammonium sulfate, ammonium nitrate, and sodium chloride were used as the test aerosols. Ammonium, sulfate, nitrate, sodium, and chloride typically accounted for 25-50% of the non-water atmospheric aerosol mass. The results showed that aerosols could affect troposheric reactions. However, these effects would depend on both the aerosol composition and the type of organic compound considered.
