City Desk :
Dhaka’s air quality was categorised as ‘moderate’ for the second consecutive day on Wednesday morning.

With an air quality index (AQI) score of 84 at 8:45 am, Dhaka ranked 17th on the list of cities worldwide with the worst air quality.

Pakistan’s Lahore, India’s Delhi and Vietnam’s Hanoi occupied the first three spots on the list, with AQI scores of 197, 168 and 164, respectively.

When the AQI value for particle pollution is between 101 and 150, air quality is considered ‘unhealthy for sensitive groups’, between 150 and 200 is ‘unhealthy’, between 201 and 300 is said to be ‘very unhealthy’, while a reading of 301+ is considered ‘hazardous’, posing serious health risks to residents, reports UNB.

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.
