Delhi chokes on hazardous air quality in post-Diwali pollution spike

Delhi's air quality index plummeted into the 'very poor' category on Thursday morning, a day after Diwali festivities concluded, with monitoring stations registering readings well above safe thresholds. The deterioration in air quality follows the traditional post-Diwali spike in pollution levels, driven by a combination of festival firecrackers, stubble burning in neighboring states, and meteorological conditions that trap pollutants over the region.

The India Meteorological Department indicated that wind speeds remained low during the overnight hours, preventing the dispersal of accumulated particulate matter. Air quality monitoring agencies advised residents, particularly those with respiratory conditions and elderly citizens, to limit outdoor activities and use air purifiers indoors. Schools in several areas issued health advisories to parents and staff.

The pollution episode underscores the recurring seasonal challenge facing the Delhi metropolitan area, which regularly experiences severe air quality degradation during winter months. Environmental authorities have called for stricter implementation of anti-pollution measures and continued coordination with neighboring state governments to curb stubble burning activities in agricultural regions.
