Experts have said that unfavourable meteorological conditions like calm winds, low temperatures, and smoke emanating from farm fires in neighbouring states Punjab and Haryana have led to a dense layer of haze.

The CPCB said that toxic air could affect healthy people and seriously impacts those with existing diseases. The AQI could worsen further in the coming days with a rise in farm fires, Diwali celebrations, and the onset of the winter season.
The CPCB on Thursday said that the share of stubble burning in Delhi's air pollution rose to 42 per cent, the maximum so far this season. On Wednesday, stubble burning had contributed only five per cent to Delhi's pollution, 10 per cent on Tuesday and 16 percent on Monday, and 40 per cent a day before. Last year, the farm fire contribution to Delhi's pollution had peaked to 44 per cent on November 1.
On Thursday, Chief Minister Arvind Kejriwal urged the residents of Delhi not to play with the lives of their family by bursting firecrackers on the occasion of Diwali. He asked Delhiites to observe a cracker-free Diwali to check the rising air pollution in the national capital.
