According to data from international air quality monitoring firm IQAir, released on Tuesday morning, Delhi recorded an air quality index (AQI) score of 299, placing it at the top of the world’s most polluted cities list. Dhaka ranked fifth with a score of 220, while Kolkata stood seventh. Both Delhi and Dhaka’s air quality levels were categorized as 'very unhealthy'. The data was collected around 8:30 a.m., when dry winter weather typically worsens air pollution in the region.
The IQAir ranking also placed Dakar, Senegal, second with a score of 243; Cairo, Egypt, third with 229; Hanoi, Vietnam, fourth with 221; and Krasnoyarsk, Russia, sixth with 201. The report noted that AQI scores between 201 and 300 are considered 'very unhealthy', prompting health advisories for children, the elderly, and those with illnesses to stay indoors and for others to limit outdoor activities.
The report highlighted that during the dry winter season, Dhaka often experiences persistently high pollution levels, contributing to its position among the world’s most polluted cities.
