Dhaka has ranked fourth on the list of cities worldwide with the worst air quality this morning.

With an AQI score of 242 at 8:40am, Dhaka’s air was classified as ‘very unhealthy’, according to the air quality index.

Bosnia Herzegovina’s Sarajevo, India’s Delhi and Ghana’s Accra occupied the first, second and third spots on the list, respectively, with AQI scores of 420, 309 and 242.

When the AQI value for particle pollution is between 101 and 150, air quality is considered ‘unhealthy for sensitive groups’, between 150 and 200 is ‘unhealthy’, between 201 and 300 is said to be ‘very unhealthy’, while a reading of 301+ is considered ‘hazardous’, posing serious health risks to residents.

The AQI in Bangladesh is based on five 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.
