Delhi's air quality plunges to severe levels post-Diwali

The Delhi region is grappling with a significant spike in air pollution levels, with the air quality index settling in the 'very poor' category at 303. The deterioration follows the Diwali festival period, when pollution levels typically surge across northern India due to a combination of factors including festive activities and seasonal weather patterns.

Stubble burning in neighbouring states has emerged as a major contributor to Delhi's worsening air quality. Farmers in Punjab, Haryana and Uttar Pradesh have begun clearing their fields after harvest season, and the large-scale burning of crop residue has significantly elevated pollution levels across the region. These emissions travel to Delhi and its surrounding areas, degrading air quality substantially.

The seasonal deterioration in air quality coincides with meteorological changes in winter months, when temperature inversions trap pollutants closer to ground level. Wind patterns during this period typically carry emissions from agricultural areas toward Delhi, intensifying the air quality crisis. Residents and health authorities have expressed concern over the prolonged exposure to hazardous pollution levels.

The 'very poor' air quality classification poses serious health risks, particularly for vulnerable populations including children, the elderly, and individuals with pre-existing respiratory and cardiovascular conditions. Authorities are monitoring the situation closely as pollution levels remain a critical public health concern for the national capital region.
