The current study assessed the air quality of area 3 most populated cities of Punjab- Ludhiana, Jalandhar and Amritsar. Air quality Index (AQI) parameters- PM2.5, PM10, O2, NO3, SO2, CO of recent 3 years (2021, 2020, 2019) of the 3 areas is studied. The highest annual average concentration of PM2.5 is found to be 163.5 Î¼g/mÂ³ in December 2021 at Ludhiana, while the lowest value found to be 55.2 Î¼g/mÂ³ in Jalandharin September, 2021.

Excessive concentrations of pollutants in air have triggered a state of emergency in polluted areas around the world, particularly in developing countries like India.
