Short summary
We show the presence of dissolved inorganic salts could reduce the overall heterogeneous reactivity of organic compounds with gas–phase OH radicals at the surface by lowering the surface concentration of organic compounds. Until recently, the kinetic parameters reported in the literature were mostly measured based on experiments with pure organic particles. The lifetime of organic compounds or chemical tracers against heterogeneous OH reaction in the atmosphere could be longer than expected.
