India’s air pollution levels are expected to worsen in 2022. On November 7, Katihar in Bihar had the highest AQI (Air Quality Index) of 360 among 163 Indian cities, according to data released by the Central Pollution Control Board.
According to the data, Delhi’s AQI was 354, Noida’s was 328, and Ghaziabad’s was 304. Begusarai (Bihar), Ballabgarh, Faridabad, Kaithal, and Gurugram (Haryana), as well as Gwalior (MP), were among the most polluted cities on Monday.
The findings should serve as a wake-up call for India. On Wednesday, the Indian Agricultural Research Institute (IARI) reported 3,634 farm fires in Punjab, the most this year.
Environment Minister Gopal Rai has appealed to the chief ministers of Uttar Pradesh and Haryana to take measures to divert trucks carrying non-essential goods on peripheral expressways to avoid traffic jams at the capital’s borders in order to reduce vehicular emissions.
Due to unfavourable transport-level winds, the share of stubble burning in Delhi’s PM2.5 pollution dropped to 21% on Saturday from 30% on Friday, according to Safar, a forecasting agency under the Ministry of Earth and Sciences.
Transport-level winds blow in the atmosphere’s lowest two layers, the troposphere and stratosphere, carrying smoke from farm fires to the National Capital Region.
The Air Quality Index (AQI) measures the concentration of PM 2.5 levels, which are linked to chronic respiratory diseases. PM 2.5 particles are fine particles less than 2.5 microns in size that can enter the bloodstream and penetrate the lungs and heart.
Not only does toxic air harm healthy lungs, but it has also been linked to premature deaths in people suffering from respiratory illnesses. According to Greenpeace, air pollution killed over 1.2 million Indians prematurely in 2017.
