AQI today: Following Diwali, major cities in India are facing rising pollution levels.

AQI today: As Diwali celebrations come to an end, the aftermath has been rising pollution levels in major cities, including Delhi.

According to Central Pollution Control Board (CPCB) data, it recorded an AQI of 393 on 22 October at 7:10 AM.

Two days after Diwali, cities across the country continue to grapple with ‘very poor’ air quality.

However, the pollution woes come at a time when the Supreme Court lifted the years-old blanket ban on the burning of firecrackers in Delhi-NCR. The apex court this time permitted the use of green crackers on Diwali, but within a limited timeframe. Many flouted the top court's directives, exacerbating the air quality concerns.

High pollution levels in the ‘very poor’ range were also reported in Okhla, Sirifort Ashok Vihar, Dwarka Sector 8, Bawana, Mathura Road, Pusa, North Campus, ITO, around Jawaharlal Nehru Stadium and Dilshad Garden. Meanwhile, NISE Gwal Pahari, Lodhi Road, IGI Airport, and NSIT Dwarka stations recorded the best air quality in the city that fell in the “poor” range.
