Capital Dhaka has once again topped the list of cities worldwide with the worst air quality as the AQI score of Dhaka’s air quality was 254 at 9:00 am on Thursday.
According to the air quality index, Dhaka’s air was classified as “very unhealthy”, posing serious health risks to residents, Ghana’s Accra, India’s Mumbai and Nepal’s Kathmandu occupied the second, third and fourth spots on the list, with AQI scores of 191, 179 and 173, 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.
The AQI, an index for reporting daily air quality, informs people how clean or polluted the air of a certain city is and what associated health effects might be a concern for them.
Dhaka has long been grappling with air pollution issues. Its air quality usually turns unhealthy in winter and improves during the monsoon.
