The 'severe' category poses serious health risks, especially due to fine particulate matter (PM2.5), which can penetrate deep into the lungs and enter the bloodstream, causing long-term health issues

At 6 am on Saturday, the CPCB recorded Delhi’s AQI at 419, which placed it back in the ‘severe’ category.

At 6 pm, AQI breached the 400-mark at 23 stations as several stations reported 'severe' air quality throughout the day.

According to SAFAR-India data, the air quality index (AQI) of Delhi has improved to 379, a significant dip from Wednesday’s 424 and Tuesday’s 492 levels.

Amid the persistent smog crisis affecting Delhi and other regions of North India, the following are the top 10 cities in India currently enjoying relatively clean air, as indicated by their impressive AQI readings by CPCB of November 2024.

Delhi recorded a minimum temperature of 10.2 degree Celsius, 2.1 notch below the season’s average, the India Meteorological Department said. At 9 am, the national capital recorded an AQI of 376, according to the Central Pollution Control Board (CPCB).

Delhi was listed as India's most polluted city Thursday as a weeks-long air quality crisis gripping northern India has shown few signs of letting up.

The AQI in Anand Vihar was recorded as 457; the AQI in Ashok Vihar was 455; Chandni Chowk's AQI was 439 and RK Puram recorded an AQI of 421.

Experts attribute the deteriorating conditions to a mix of vehicular emissions, industrial pollution, and unfavourable weather patterns

A thick layer of smog engulfed the national capital on Friday while the air quality index in Delhi remained in the 'very poor' category, according to the Central Pollution Control Board (CPCB). Drone visuals from the Mayur Vihar and Kalindi Kunj areas revealed the thick density of smog.
