Delhi chokes as post-Diwali pollution soars despite firecracker ban

Delhi's air quality index (AQI) reached critical levels in the days following Diwali, with environmental monitoring stations across the city registering severe readings on Wednesday. Fifteen locations recorded AQI values in the severe category, indicating hazardous air conditions for residents and exacerbating existing respiratory health risks.

The post-festival pollution surge comes despite a ban on firecracker sales and bursting that was enforced ahead of the celebration. However, the restriction was extensively flouted during Diwali festivities, with residents across multiple areas openly defying the order. The widespread disregard for the prohibition significantly contributed to the rapid deterioration of air quality in the national capital.

Severe air quality conditions typically necessitate health advisories and encourage vulnerable populations—including children, elderly residents, and those with pre-existing respiratory conditions—to limit outdoor activities. The pollution levels are also expected to impact visibility and transport operations across the city.

Environmental authorities have urged residents to comply with anti-pollution measures and restrict outdoor activities during the acute pollution period. The deteriorating air quality reflects the cumulative effect of firecracker emissions combined with seasonal meteorological factors and existing vehicular and industrial pollution in the region.
