Ground Level Ozone that has a chemical structure known as O3, is a pollutant formed with particular compounds in the presence of sunlight. The general formula for this reaction is as follows: VOCs + NOx + Sunlight = Ozone.
VOC stands for volatile organic compounds. These are ingredients that are commonly used in homes, in the form of fuels, cleaning, disinfecting, paints, varnishes, wax, cosmetic, degreasing, etc. Some of these are relatively safe, while some are quite toxic. Though there are many manmade sources of VOCs, there are many natural sources too, such as trees (CAQF Fact Sheet two, 2007).
The next constituent in the equation is NOx, which stands for nitrogen oxide gases. This is a general term that is used to refer to a group of highly reactive gases. All these gases contain nitrogen and oxygen in differing quantities. Main sources of NOx include automobiles, electric utilities, as well as commercial, industrial and residential sources that use fuels (Cornwall County Council, 2007).
With these two ingredients reacting in the presence of sunlight and hot weather conditions, ground level ozone forms. When this forms, cloud cover and wind direction are affected. Also low wind speeds result1.
