Update : 21 Mar 2024, 10:31

With an air quality index (AQI) score of 168 at 9 am Dhaka ranked third on the list of cities worldwide with the worst air quality on Thursday morning. Its air quality continued to be in the 'unhealthy' zone. 

An AQI between 101 and 200 is considered 'unhealthy', particularly for sensitive groups.

Pakistan’s Lahore and Nepal’s Kathmandu occupied the first two spots on the list, with AQI scores of 207 and 171, respectively.

An AQI between 201 and 300 is said to be 'poor', 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.

Air pollution consistently ranks among the top risk factors for death and disability worldwide. Breathing polluted air has long been recognised as increasing a person’s chances of developing a heart disease, chronic respiratory diseases, lung infections and cancer, according to several studies.
