The important role of heterogeneous chemical reactions and processes between gaseous pollutants and atmospheric aqueous droplets (clouds, fogs and rain) or particulate matter in tropospheric chemistry is reviewed. The main features of this article are sulfur dioxide oxidation (Chapter 3), transformation of nitrogen oxides (Chapter 4) and transformation/decomposition of organic matter (Chapter 5).
