The severe air quality poses significant health risks, particularly for children and the elderly.

The Delhi NCR region is currently grappling with a thick blanket of smog, with temperatures dropping and the Air Quality Index (AQI) breaching the 450-mark, categorised as 'severe'. Residents on Monday (Dec 15) woke up to a dense smog, which reduced visibility to merely 5-10 metres. The condition prompted the authorities to issue advisories and take measures to control air pollution. Online users have shared videos from their homes and offices to show the current situation in the NCR region. A user posted a video on Instagram, showing the condition of roads in Delhi at 6.30 am on December 15. In the comment section, one user called it "dangerous". 

The severe air quality is attributed to a combination of factors, including weak surface winds, foggy conditions, and emissions from vehicles, industries, and biomass burning. The situation is expected to worsen with colder nights and low wind speeds.
 

The Commission for Air Quality Management (CAQM) has imposed measures under the Graded Response Action Plan (GRAP) stage IV, including restrictions on construction activities, industrial operations and vehicular movement. Schools in Delhi and surrounding areas have been directed to conduct classes online or in hybrid mode.

The severe air quality poses significant health risks, particularly for children, the elderly and those with pre-existing medical conditions. Residents are advised to limit outdoor activities and take necessary precautions.
