Delhi’s air quality has been deteriorating over the past few days and became a major cause of concern after it crossed 400 mark on 500 AQI scale on November 11 and entered ‘severe’ range. On Wednesday, the national capital recorded an AQI of 413 at 7:05 AM, according to Central Pollution Control Board.
Among a total of 39 air quality monitoring stations, as many as 33 recorded air quality in severe category. The impact of chronic exposure to air pollution extends far beyond respiratory ailments. Research pointed to long-term health consequences, including cancer risk and weakening the body’s immunity.
According to the State of Global Air 2025 report, India registered over two million deaths linked to toxic air in 2023. Experts terms the rising concentrations of PM2.5 in South Asia among the highest worldwide and as an indicator of deepening environmental and human crisis.
The Central government on November 11 invoked Stage III of the Graded Response Action Plan (GRAP) in Delhi-NCR after average Air Quality Index (AQI) of the national quality rose sharply on Tuesday. The Commission for Air Quality Management (CAQM) blamed stable atmosphere and unfavourable weather conditions for the rising pollution level which allows pollutants to accumulate close to the surface.
Several anti-pollution measures are being taken to bring down pollution level and as a precautionary measure schools up to Class 5 in Delhi-NCR shifted to a hybrid mode of teaching. This allows students to attend classes either online or in person, based on the availability of digital infrastructure like computers and internet access at home.
