Ozone Pollution:
As per the CPCB, Ground-level ozone (O3) has started to emerge as Delhi’s lead pollutant during the day, particularly after rain, according to data from the Central Pollution Control Board (CPCB)
- Ground-level Ozone is a type of pollutant that is produced when two primary pollutants, nitrogen oxides and volatile organic compounds, react in sunlight and stagnant air.
- It is referred to as a “secondary” pollutant because it is not directly emitted, but rather formed through chemical reactions between these primary pollutants.
- The Central Pollution Control Board of India (est. 1974; HQ: New Delhi) is a statutory organization under the Ministry of Environment, Forest and Climate Change.
- It was established in 1974 under the Water Act, 1974, but is entrusted with the powers and functions under the Air Act, 1981.
