New Delhi, Nov 20 || Delhi-NCR's air quality deteriorated sharply on Thursday, as the Air Quality Index (AQI) touched 400, right on the threshold of the 'severe' category, and a thick blanket of toxic smog continued to hang over the region. Several pollution hotspots saw the AQI go over the 400 mark.
According to the Central Pollution Control Board (CPCB), stagnant winds and falling temperatures have trapped pollutants close to the surface, worsening air conditions across the national Capital and NCR.
Data from the CPCB-developed Sameer App showed Wazirpur recording the highest AQI at 477, placing it firmly in the 'severe' category. Lodhi Road reported the lowest AQI among 39 monitoring stations with a reading of 269, which still falls under the 'poor' category.
