Ozone
A reactive form of oxygen which at ground level is harmful to plants and animals. In the upper atmosphere it acts as a beneficial filter for ultraviolet radiation, but is destroyed by halons and CFCs. At ground level it is produced by reactions between VOCs and NOx and is a constituent of photochemical smog, which makes it an irritant and can cause breathing difficulties.
Ozone Precursors
Chemical compounds, such as carbon monoxide, methane, nonmethane hydrocarbons, and nitrogen oxides, which in the presence of solar radiation react with other chemical compounds to form ozone.
