what is the main cause of ozone pollution
Ozone pollution is a form of pollution which is characterized by high concentrations of ozone, a form of oxygen, at ground level. Exposure to ozone can cause serious health problems in plants and people, and ozone pollution is a major problem in some regions of the world. It tends to increase during periods of high temperatures and sunny skies, which is why bad air advisories are often issued on seemingly nice days.
Air pollution leads to ozone pollution and acid rain. CFC compounds, used in aerosol sprays prior to 1995, destroy the ozone layer. Ozone pollution can cause damage to human respiratory tracts. Ozone can damage the vascular system of plants.
Ozone Pollution. Ground level or bad ozone is not emitted directly into the air, but is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC) in the presence of sunlight.
