Delhi's air quality worsens to 493 AQI, exceeding WHO limits, as smog blankets northern India, prompting restrictions and health concerns.
The overall AQI of Delhi on Monday (November 18, 2024) worsened to 493 at 3 p.m., according to Central Pollution Control Board (CPCB) data.
Delhi authorities directed all schools to move classes online and tightened restrictions on construction activities and vehicle movements, citing unfavourable meteorological conditions and low wind speed.
AQI is a measurement of air pollution on a scale of 0-500. A higher AQI means an increase in air pollution.
At least nine of the 37 stations measuring air quality in Delhi maxed out at 500 by 3 p.m., the CPCB data showed. This indicates that Delhi’s actual air quality is worse than 493.
Air pollution in Delhi on Monday afternoon was over 26 times the limit prescribed by the World Health Organisation (WHO), according to official data.
The overall level of PM2.5 (a chief pollutant) in Delhi was 401.1 micrograms per cubic meter at 2 p.m. on Monday, as per CPCB data — about 26.74 times the WHO’s permissible limit of 15 micrograms per cubic meter for a 24-hour period.
A thick blanket of toxic smog also engulfed most parts of northern India, as a result of which, visibility dropped to 100 m in Delhi and Chandigarh.

The silent reading movement in the Mylapore-Mandaveli-RA Puram area showed up first at Nageswara Rao Park around two years ago, with modest ambitions, when Balaji launched it along with other reading enthusiasts from the region. This initiative has now moved parks, and seems to set to get entrenched in one. Due to renovation work at Nageswara Park, the reading session became irregular. With the Nageswara Rao park work gaining more surface area, it had to be shifted elsewhere. And it seems set to continue with a newly discovered green patch in RK Nagar in the Sundays to follow.
