Frequently Asked Questions
What is AQI in India?
AQI (Air Quality Index) in India measures air pollution levels based on concentrations of pollutants like PM2.5, PM10, NO₂, SO₂, CO, and O₃.
Why is air pollution worse in winter?
Because atmospheric conditions like low wind and temperature inversion trap pollutants near the ground.
What are the main sources of air pollution in India?
Vehicles, industries, construction dust, crop burning, and household fuels.
How is air pollution measured in India?
It is monitored using CPCB systems such as CAAQMS, NAMP, and other air quality monitoring networks.
