Smog Smog” was originally coined as a mixture of “smoke” and “fog” Historically used to describe air pollution produced from the burning of coal Photochemical smog is formed through the reaction of solar radiation with airborne primary pollutants (introduced into the atmosphere through automobile emissions and industrial processes) producing secondary pollutants The mixture of these primary and secondary pollutants forms photochemical smog.

▪ Ultraviolet light can split nitrogen dioxide into nitric oxide and monatomic oxygen; this monatomic oxygen can then react with oxygen gas to form ozone (all are secondary pollutants)
