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.
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.
