Air quality across the national capital has taken a severe downturn with the arrival of early winter conditions. Pollution monitors throughout Delhi show that toxic haze has begun blanketing major neighborhoods, pushing the overall environment into unhealthy territory. Data from the Central Pollution Control Board reveals that most monitoring stations across the capital recorded air quality in the poor zone. Old Delhi commercial hub Chandni Chowk turned out to be the most impacted pocket on Thursday morning, registering an Air Quality Index reading of 306, which firmly falls in the very poor category.
Stricter Measures Enforced Under GRAP Stage One
With air pollution levels escalating steadily, the Commission for Air Quality Management moved swiftly to enforce Stage 1 of the Graded Response Action Plan across Delhi and the wider National Capital Region. The emergency plan brings mandatory curbs focused on keeping airborne dust and vehicular emissions under check. Building sites must now adhere to rigorous anti-dust protocols, including covering construction materials and operating water-spraying mechanisms to suppress floating particulate matter.
Municipal authorities have been instructed to monitor and penalize the open burning of solid municipal waste, biomass, and dry leaves in open grounds. On the roads, transport enforcement squads are stepping up physical inspections of valid Pollution Under Control certificates. Strict punitive measures and impounding drives are being rolled out against visibly polluting commercial vehicles as well as petrol and diesel automobiles that have exceeded their legally permitted operational lifespans.

Worst Smog Spell Recorded in Over Hundred Days
The sudden slump in atmospheric purity gained momentum on Wednesday when Delhi's overall citywide Air Quality Index climbed to 245. This marked the worst atmospheric reading seen in the city in more than a hundred days, representing the formal arrival of poor category air for this season. Prior to this episode, a similarly deteriorated reading had occurred on July 13, when the citywide index touched 246.
This sharp descent in ambient air purity occurred immediately following the Dussehra festival celebrations. During the event, hundreds of towering effigies of Ravana packed with firecrackers were ignited across neighborhoods in Delhi and adjoining NCR towns, accompanied by widespread bursting of festive fireworks. While this festive activity is widely considered a key contributor to the sudden accumulation of smoke, definitive scientific evidence linking the spike directly to the celebrations has not yet been presented by environmental authorities.
