Dhaka continued to occupy the top spot in the list of cities around the world with the worst air quality for the third consecutive day this morning.
With an air quality index (AQI) score of 288 at 9:30 am, the capital of Bangladesh ranked first in the list of cities with the worst air quality.
An AQI between 151 and 200 is considered "unhealthy," 201 and 300 "very unhealthy," and 301 to 400 is considered "hazardous," posing serious health risks to residents.
In Bangladesh, the AQI is based on five criteria pollutants – particulate matter (PM10 and PM2.5), NO2, CO, SO2 and ozone.
Breathing polluted air has long been recognised as increasing a person's chances of developing heart disease, chronic respiratory diseases, lung infections and cancer, according to several studies.
