Smog This is a term used to describe the mixture of smoke and fog. Smog occurs when high concentrations of moisture is combined with smoke (often containing oxides of sulfur and nitrogen) in the presence of high temperatures or thermal inversions and the absence of wind.
Photochemical smog is a mixture of many organic and inorganic gas phase molecules. It contains ozone, nitrogen oxides, and organic molecules. Typically, we estimate the amount of smog by measuring the concentration of one component, ozone.
