New Delhi’s air quality has reached alarming levels, surpassing WHO’s recommended limits by 25-30 times last week. The city faces seasonal air pollution between October and January, leading to business closures, school suspensions, and transportation disruptions. Government data shows that PM 2.5 levels—fine particles dangerous to respiratory health—have hit 350 micrograms per cubic meter in some areas, categorized as “very poor” to “severe.” Experts warn conditions may worsen with Diwali firecrackers and crop burning nearby, urging residents to stay indoors and use public transport.
