The city's air quality deteriorated to the 'very poor' category on Saturday due to slow wind speed at night and a dip in the temperatures and it is expected to remain in the same position for a few more days, according to the Centre's Air Quality Early Warning System for Delhi.

The capital's air quality in October 2023 has been worse compared to the last two years and meteorologists attribute it to the lack of rainfall.
According to Delhi Environment Minister Gopal Rai, though the number of stubble-burning incidents in Punjab has reduced, vehicular emissions have emerged as a major contributor to the air pollution in the city.
He demanded that the Centre impose a strict ban on buses operating with poor-quality diesel in the National Capital Region (NCR) areas of Haryana, Uttar Pradesh and Rajasthan.
