ozone


There is ozone found in two areas. One is in the upper regions of the atmosphere and the other area is the ground level. They are both made up of O3, but the ground level is made from chemical reactions of nitrogen (NOx) and volatile organic compounds (VOC). Both of these chemicals mostly come from the burning and evaporation of fossil fuels like gasoline, natural gas, and coal.The ozone in the upper regions of the atmosphere protects us from the harmful rays from the sun, but the ground level ozone is the main reason for smog. The ground level ozone is very harmful to elderly people, young people, and people with respiratory problems. It can also contribute to producing a respiratory problem. The ground level ozone is also harmful to sensitive vegetation and ecosystems, including forests, parks, wildlife refuges and wilderness areas.
