Dhaka's air quality continued to be in the 'hazardous' zone this morning, posing serious health risks to residents of the densely populated capital of Bangladesh.

With an air quality index (AQI) score of 372 at 8:50am today, Dhaka ranked first in the list of cities with the worst air.

For all latest news, follow The Daily Star's Google News channel.

Yesterday, the city's AQI score was 319, which is also in the 'hazardous' zone.

An AQI between 151 and 200 is said to be 'unhealthy', between 201 and 300 is considered 'very unhealthy', and 301 to 400 is considered 'hazardous'.

Uzbekistan's Tashkent and Mongolia's Ulaanbaatar occupied the second and third spots in the list, with AQI scores of 288 and 219, respectively.

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.
