Hyderabad's air quality plunges to hazardous levels post-Deepavali

Hyderabad's air quality took a sharp turn for the worse immediately after Deepavali festivities, with pollution levels soaring into the hazardous category. The Air Quality Index averaged 509 during the night, well above the threshold considered safe for public health.

Particulate matter with a diameter of 2.5 micrometers—the most dangerous form of air pollution—reached 392 micrograms per cubic meter at 9:30 p.m., according to air quality monitoring data. This represents a significant spike from baseline levels and poses serious health risks, particularly for vulnerable populations including children, the elderly, and those with respiratory conditions.

The deterioration in air quality is primarily attributed to widespread firework displays during Deepavali celebrations. Firecracker emissions release substantial quantities of particulates and gaseous pollutants directly into the atmosphere, overwhelming existing air quality management measures.

The hazardous air quality necessitates immediate health precautions for residents. Authorities typically advise limiting outdoor activities, using air purifiers indoors, and wearing N95 masks when venturing outside during such pollution events. The situation underscores the persistent challenge cities across India face in balancing festive traditions with environmental and public health concerns.
