What are the specific AQI safety guidelines for pregnant women and the elderly? Doctor explains
The Air Quality Index (AQI) is a standardised system that measures and reports daily air pollution levels. It tells you how clean or polluted the current air is. Major components of the AQI index are Ground-level ozone (O₃), Particle pollution/Particulate matter (PM2.5 and PM10), Carbon monoxide (CO), and Nitrogen dioxide (NO₂).
