Which of the following is most polluted city in India by particulate matter (2.5) ?
Kanpur
PM2.5 refers to fine particulate matter with a diameter of 2.5 micrometres or less. These particles penetrate deep into the lungs and bloodstream and are linked to asthma, heart disease and lung cancer, so annual PM2.5 concentration is the standard yardstick for ranking cities by air pollution.
In the WHO Ambient Air Quality Database (2018), which ranked cities by annual mean PM2.5 concentration, Kanpur in Uttar Pradesh emerged as the most polluted city in India and among the worst in the world, driven by industrial emissions, vehicular exhaust, road dust and biomass burning.
Delhi is famous for severe winter smog and was repeatedly ranked the most polluted national capital, while Varanasi and Gaya also feature in the list of highly polluted Indian cities, but among the cities given here Kanpur recorded the highest PM2.5 level in that ranking.
Hence, the answer is Kanpur.
