Delhi's air quality plunges to severe levels as post-Deepavali pollution peaks

Delhi's air quality has slipped into the severe category on Monday, with Air Quality Index readings surging above 400 across multiple monitoring stations in the national capital. The sharp deterioration follows Deepavali festivities, during which increased firecracker emissions compounded existing pollution levels across the region.

The hazardous air conditions are not confined to Delhi alone. Major metropolitan areas including Mumbai and Chennai woke Monday morning to heavy smog cover, while Lucknow and several other cities across northern and western India have also experienced significant air quality degradation. Residents in affected areas have reported reduced visibility and respiratory discomfort.

The pollution spike reflects the confluence of several factors including post-festival emission levels, meteorological conditions that trap pollutants near ground level, and seasonal atmospheric patterns characteristic of this time of year. Air quality experts have attributed the severe readings to a combination of firecracker residue and existing background pollution levels that characterize the post-Deepavali period.

Authorities in affected cities have issued advisories urging vulnerable populations, including children, elderly residents, and those with respiratory conditions, to limit outdoor exposure and take necessary precautions. The situation underscores annual challenges cities face in managing air quality during the festive season.
