Dhaka air quality moderate Thursday morning

Dhaka's air quality was in the moderate zone on Thursday morning.

With an air quality index (AQI) score of 92 at 8:55am, Dhaka ranked 17th in the list of cities worldwide with the worst air quality.

United Arab Emirates’ Dubai, Uganda’s Kampala and Indonesia’s Jakarta occupied the first, second and third spots on the list, with AQI scores of 181, 160 and 160 respectively.

An AQI between 50 and 100 is considered “moderate” with acceptable air quality. However, there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.

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.

As per the World Health Organization (WHO), air pollution kills an estimated seven million people worldwide every year.
