Delhi's environment minister, Gopal Rai, said that the next 15-20 days will be critical in terms of air quality. The minister highlighted that the temperature drop and decreased air speed have resulted in lower pollutant levels. The situation is under control due to efforts in 13 hotspots, although vehicle pollution remains a concern. A meeting will be held to analyze the Graded Response Action Plan. The air quality index in Delhi has remained in the 'very poor' category for the past few days. Morning walkers have reported discomfort due to pollution.
