Dhaka's air quality was in the 'unhealthy' zone on Monday morning. With an air quality index (AQI) score of 155, Dhaka ranked seventh in the list of cities worldwide with the worst air quality. An AQI between 150 and 200 is considered 'unhealthy', reports UNB.

Thailand's Chiang Mai, India's Delhi, and Pakistan's Lahore occupied the first three spots in the list, with AQI scores of 195, 173, and 167, respectively.

An AQI between 201 and 300 is said to be 'very unhealthy', while a reading of 301 to 400 is considered 'hazardous', posing serious health risks to residents.

In Bangladesh, the AQI is based on five criteria pollutants -- Particulate Matter (PM10 and PM2.5), NO2, CO, SO2 and Ozone.

Dhaka has long been grappling with air pollution issues. Its air quality usually turns unhealthy in winter and improves during the monsoon.
