Delhi-NCR pollution LIVE UPDATES: A toxic haze engulfed the National Capital as the Air Quality Index (AQI) crossed the 400 mark on Tuesday morning, affecting visibility and delaying flights and trains.
Delhi-NCR pollution LIVE UPDATES: The national capital has been experiencing toxic smog engulfing the city, severely impacting air quality and travel disruptions. Delhi's air quality has reached hazardous levels, with the Air Quality Index (AQI) exceeding 400 in several areas across Delhi-NCR, prompting authorities to implement strict anti-pollution measures.
India’s pollution watchdog classifies AQI levels of 101–200 as moderate, 201–300 as poor, 301–400 as very poor, and anything above 400 as severe. Currently, the Delhi AQI is in the 'very poor' range at 373, slightly improved from 'severe' levels of 401 on Monday. Delhi's Anand Vihar and ITO recorded AQI around 400 as of 10 am on Tuesday.
In view of the worsening situation, the Commission for Air Quality Management (CAQM) invoked Stage IV of the Graded Response Action Plan (GRAP) after the Air Quality Index (AQI) neared the 'Severe Plus' mark at 450. "Keeping in view the prevailing trend of air quality and in an effort to prevent further deterioration of air quality in the region, the CAQM Sub-Committee on GRAP decides to invoke all actions as envisaged under Stage-IV of the extant GRAP - 'Severe+' Air Quality (DELHI AQI > 450), with immediate effect, in the entire NCR. This is in addition to the actions under Stages I, II & III of extant GRAP already in force in NCR," the order stated.
Further, the NCR Pollution Control Boards/Committee and other concerned agencies have been asked to intensify preventive measures to prevent further deterioration of air quality in the region, the order stated. Several parts of the national capital remained enveloped in a dense layer of toxic smog, severely affecting visibility and causing discomfort to residents.
