As many as 15 cities out of world’s 20 worst polluted cities are from India while a total of 35 cities from the country find a place in the globe’s 50 most polluted cities. Bhiwadi, the industrial town of Alwar district in Rajasthan, has left behind Delhi in topping the air pollution charts on the world index for the year 2021.
IQAir, which monitors air pollution around the world, has released its 2021 Global Air Quality Report covering 6,475 cities in 117 countries. The average level of PM-2.5 has been recorded at 106.2 in Bhiwadi in 2021 against 96.4 in Delhi. PM-2.5 is the unit to measure the level of pollution. In the category of cities, Ghaziabad is at number two after Bhiwadi, where the pollution level is 102.
As the pollution level remains high in this town of the desert state, a separate regional office has been set up within the Alwar district.
