The Centre's panel on Delhi-NCR's air quality on Monday revoked the Stage 2 curbs under the Graded Response Action Plan following a dip in pollution levels due to favourable meteorological conditions.
Delhi's 24-hour average air quality index stood at 186 at 4 p.m., significantly below the 300-mark that triggers Stage 2 restrictions.
The India Meteorological Department and Indian Institute of Tropical Meteorology predict that the Air Quality Index will likely remain in the moderate to poor category.
The Commission for Air Quality Management in NCR and adjoining areas attributes the improved air quality to better mixing height, ventilation coefficient, and "much favourable conditions for dispersion of pollutants".
With the revocation of Stage 2 curbs, inter-state buses from NCR states are now permitted to enter Delhi.
During winters, the Delhi-NCR region enforces restrictions under GRAP, which categorizes air quality into four stages—Stage I (Poor, AQI 201-300), Stage II (Very Poor, AQI 301-400), Stage III (Severe, AQI 401-450), and Stage IV (Severe Plus, AQI above 450).
Unfavourable meteorological conditions, combined with vehicle emissions, paddy-straw burning, firecrackers, and other local pollution sources, lead to hazardous air quality levels in Delhi-NCR during winters.
Trade Setup For Feb. 25: Nifty 50 Support Slips To 22,500 Levels After Fifth Straight Day Of DeclineFive of the six metro cities reported moderate air quality, while Kolkata remained in the satisfactory category.
The Supreme Court has suggested involving Virat Kohli in an awareness campaign promoting a firecracker free Diwali. The court also questioned the enforcement of existing restrictions and sought stronger action against violations in Delhi NCR.
The action is part of a broader crackdown by Mumbai's civic and housing authorities to curb deteriorating air quality and dust pollution caused by ongoing construction and demolition activities across the city.
The eyes are directly exposed to the surrounding environment, making them vulnerable to airborne pollutants.
