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.
There are two major types of smog: photochemical and industrial smog. Photochemical smog is created through a reaction by which air pollutants are struck by sunlight, and form â¦ particulate matter and tropospheric ozone.The air pollutants that are most responsible for this type of smog are nitrogen oxides (NOx) and volatile organic compounds (VOCs).Photochemical is especially a problem in areas with many cars, coal-burning power plants, and the right weather conditions.hotochemical smog is created through a reaction by which air pollutants are struck by sunlight, and form â¦ particulate matter and tropospheric ozone.
