City Desk :
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 with an air quality index (AQI) score of 174 at 9:10am, reports UNB.

An AQI between 151 and 200 is considered “unhealthy” while between 201-300 is “very unhealthy”, and 301-400 is “hazardous”, posing severe health risks to residents.

Thailand’s Chiang Mai, India’s Delhi and Nepal’s Kathmandu occupied the list’s first, second and fourth spots, with AQI scores of 191, 185 and 169, 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.
