New Delhi, Nov 2: Delhi and its surrounding National Capital Region (NCR) woke up to a toxic haze on Sunday morning as the Air Quality Index (AQI) breached the 400 mark in several areas, plunging the region into the ‘severe’ pollution category.

According to data from the Central Pollution Control Board (CPCB), neighbourhoods such as Anand Vihar, Wazirpur, RK Puram, and Dwarka recorded AQI levels above 400, indicating hazardous air quality. The average AQI across Delhi stood at 372 at 6:30 a.m., already in the ‘very poor’ range, with conditions worsening throughout the day.

The thick smog, coupled with stagnant winds and rising humidity, trapped pollutants close to the ground, drastically reducing visibility and causing widespread respiratory discomfort. Residents reported symptoms including eye irritation, coughing, and difficulty breathing.

Experts attribute the spike in pollution to a combination of factors: falling temperatures, low wind speeds, vehicular emissions, and stubble burning in neighboring states. The seasonal transition into winter has further exacerbated the situation, creating an inversion layer that prevents pollutants from dispersing.

In response to the deteriorating air quality, authorities are considering the implementation of GRAP Stage III (Graded Response Action Plan), which includes measures such as banning non-BS-VI trucks, halting construction activities, and increasing parking fees to discourage private vehicle use.

Despite a Rs 3 crore cloud seeding experiment aimed at reducing pollution, officials have reported limited success. Environmentalists are urging immediate and coordinated action to prevent further health risks and long-term damage.
