In the troposphere, ozone is characterized as a secondary pollutant formed through chemical reactions between volatile organic compounds (VOCs) and nitrogen oxides (NOx) in the presence of sunlight. It is a key component of smog and can have harmful effects on human health, including respiratory issues, as well as negative impacts on vegetation and ecosystems. Unlike stratospheric ozone, which protects life from harmful UV radiation, tropospheric ozone is considered a harmful air pollutant. Its concentration can vary significantly based on factors like location, time of day, and weather conditions.
