Dhaka has topped the list of cities around the world with the worst air quality this morning (January 21, 2023).

With an air quality index (AQI) score of 249 at 8:55 am on Saturday, Dhaka ranked first in the list of cities with worst air, reports UNB.

An AQI between 151 and 200 is said to be ‘unhealthy’ while 201 and 300 is considered ‘very unhealthy’, and 301 to 400 is considered 'hazardous', posing serious health risks to residents.

India’s Kolkata and Iraq’s Baghdad occupied the second and third places with an AQI of 220 and 218 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.

As per the World Health Organization (WHO), air pollution kills an estimated seven million people worldwide every year, largely as a result of increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer and acute respiratory infections.
