As early as the 1940s and 50s, air quality in many of the major cities in the world had deteriorated to such an extent that a solution needed to be found. A major contributor to this pollution was photochemical smog and low-level ozone caused by the pollutants emitted from motor vehicles.
In atmospheric chemistry, NOx is shorthand for nitric oxide (NO) and nitrogen dioxide (NO 2), the nitrogen oxides that are most relevant for air pollution. These gases contribute to the formation of smog and acid rain, as well as affecting tropospheric ozone. NOx gases are usually produced from the reaction between nitrogen and oxygen during combustion of fuels, such as hydrocarbons, in air; especially at high temperatures, such as in car engines. In … WebPhotochemical smog is formed, in part, by the action of light on nitrogen dioxide. The wavelength of the radiation absorbed by N02 in this reaction is 197 nm. [Pg.296] The atmospheric chemistry of nitrogen is quite complex and involves literally hundreds or thousands of chemical reactions.
