The deteriorating conditions once again raised health concerns for residents and disrupted normal daily activities across the city.

According to data from the Sameer app, Delhi’s average Air Quality Index (AQI) was recorded at 366 at around 7.05 a.m. The worst air quality was reported from the Narela monitoring station, which logged an AQI of 418, the highest in the city so far on Monday. Several other areas, including Anand Vihar, Bawana, Jahangirpuri, Mundka, Rohini, and Wazirpur, also witnessed severe air quality, with AQI readings ranging between 401 and 408.

Even the least polluted parts of the city failed to offer respite. Dilshad Garden recorded the lowest AQI among the 40 monitoring stations at 301, which still falls under the “very poor” category.

As per the Central Pollution Control Board (CPCB), AQI levels between 301 and 400 are categorised as “very poor”, while readings between 401 and 500 are considered “severe”. Such pollution levels can cause respiratory discomfort, particularly among children, the elderly, and people with pre-existing health conditions.

The dense smog also affected visibility across the national capital, prompting Delhi’s Indira Gandhi International (IGI) Airport to issue a passenger advisory. In a post on the social media platform X at 7 am, airport authorities stated that low-visibility procedures were in place, although flight operations were continuing normally. Passengers were advised to contact their respective airlines for the latest updates, as delays could occur due to weather conditions.
