Chennai air quality plunges to 'poor' levels after Deepavali festivities

Air quality across Chennai nosedived to unhealthy levels on the day after Deepavali, with pollution monitors recording concerning readings across several localities. Manali Village registered the highest AQI of 296, indicating 'poor' air quality, followed by Arumbakkam at 265, both well into the hazardous range for vulnerable population groups.

Other monitoring stations across the city also reported elevated pollution levels. Kodungaiyur recorded an AQI of 215, Royapuram at 184, and Velachery Residential Area at 142, reflecting a widespread deterioration in air quality across the metropolitan area.

The spike in pollution levels follows the widespread bursting of firecrackers during Deepavali celebrations, a phenomenon observed annually in Indian cities. Air quality typically deteriorates significantly in the 24 to 48 hours following the festival as particulate matter and other pollutants accumulate in the atmosphere.

Residents, particularly those with respiratory conditions and cardiovascular ailments, have been advised to limit outdoor exposure and use appropriate protective masks. Environmental agencies typically recommend staying indoors and using air purifiers during periods of poor air quality to minimize health risks.
