DELHI MOST POLLUTED
Meanwhile, a recent analysis conducted by the independent think tank, Centre for Research on Energy and Clean Air (CREA) shows Delhi as the most polluted city in India for the month of October, with an average PM2.5 level of 111 micrograms per cubic metre.
The analysis highlights that all the top 10 polluted cities during this period were located within the National Capital Region (NCR). Alongside Delhi, the list includes Ghaziabad with 110 micrograms per cubic metre, Muzaffarnagar at 103, Hapur at 98, Noida at 93, Meerut at 90, Charkhi Dadri and Greater Noida both at 86, and Gurugram and Bahadurgarh each recording 83 micrograms per cubic metre.
The average PM2.5 concentration in Delhi for October was notably 2.5 times higher than the September average, which stood at 43 micrograms per cubic metre. The analysis also indicated that stubble burning contributed to less than 10 per cent of the PM2.5 pollution in Delhi during October. The primary increase in pollution levels was attributed to year-round emission sources.
