Delhi AQI Hits ‘Severe’ Levels as Toxic Smog Engulfs NCR

Delhi’s air quality remained hazardous on Saturday, December 21, with the AQI in Nehru Nagar reaching a concerning 434, categorized as ‘severe.’ The primary cause of the pollution was PM2.5 particles, which can deeply affect the lungs and bloodstream, posing serious health risks.

A thick layer of smog covered Delhi, Noida, Gurugram, and the surrounding National Capital Region. Of the 36 monitoring stations in the city, 20 reported air quality in the ‘severe’ category by 8 AM. These levels are considered life-threatening for vulnerable groups, including children, the elderly, and those with respiratory or heart conditions.

On Friday, the air quality was similarly poor, with a 24-hour average AQI of 429. Fourteen of the monitoring stations reported AQI levels above 450, classified as ‘Severe Plus.’

The persistent pollution is worsened by poor ventilation and lower wind speeds during the winter months. Under the Graded Response Action Plan (GRAP), Delhi is currently in Stage III (Severe), with AQI values between 401 and 450. Health experts are advising against outdoor activities, particularly for vulnerable individuals.

The India Meteorological Department (IMD) has forecast dense fog over the weekend, which could further reduce visibility and aggravate the air quality. However, light to moderate rainfall is expected by December 26, offering some hope for temporary relief.
