Ozone pollution

May 9, 2023

According to Central Pollution Control Board (CPCB) bulletins, ozone was identified as a prominent pollutant recently, when AQI was in the ‘moderate’ category.
- Ozone occurs both in Earth’s upper atmosphere (stratospheric or good ozone) and at ground level.
Ozone pollution refers to tropospheric or “ground-level” ozone.
It is formed when oxides of nitrogen (NOX) and Volatile Organic Compounds react in the presence of sunlight.
NOX is released by combustion of fossil fuels from vehicles and industries.
Ozone can also be transported long distances by wind.
Exposure to excessive ozone can cause problems breathing, trigger asthma, reduce lung function and lead to lung disease.
