An overview is presented of the new aspects in air pollution. Experimental data, as well as air pollution episodes involving smog and photochemical reactions are reviewed. Investigations of the smog mechanism have been carried out mainly with oxides of nitrogen and pure hydrocarbons, and on the basis of these experiments there is general agreement that the primary process in smog reactions is a photochemical dissociation of nitrogen dioxide with the formation of nitric oxide and atomic oxygen. The most reactive organic compounds are olefins and diolefins and they are the most frequently used in photochemical studies. Some of the less reactive species, such as aldehydes, aromatic compounds, and saturated hydrocarbons, also contribute to the production of ozone.
