While Delhi tops the list with an average AQI of 556 as listed by the IQAir service, Kolkata ranks fourth and Mumbai sixth on the full list. Cities with the worst AQI indices also include Lahore, in Pakistan, and Chengdu, in China.
Here are the ten cities with the worst air quality indicators and pollution rankings, according to IQAir:

DSS analysis showed that on Friday, rice stubble fires contributed 15 percent of Delhi’s PM 2.5 (ultrafine particulate matter with a diameter less than 2.5 micrometers), local vehicular emissions had a 25 percent share. , household emissions contributed 7 percent. percent of the particulate levels and industries in Delhi and its peripheries made up 9 to 10 percent of the city’s pollution profile.
SAFAR, the air quality monitoring station of the Union Ministry of Earth Sciences, said stubble fires accounted for at least 35 percent of the pollutants in the air on Friday.
