Dhaka, Aug 11 -- Dhaka's air quality was marked as 'unhealthy for sensitive groups' this morning.
With an air quality index (AQI) score of 123 at 10:21 am, Dhaka ranked 6th on the list of cities worldwide with worst air quality, according to IQAir.
UAE’s Dubai, Indonesia’s Jakarta and Qatar’s Doha occupied the first three spots on the list, with AQI scores of 527, 164 and 158 respectively.
An AQI between 50 and 100 is considered ‘moderate’ with acceptable air quality. However, there may be a health concern for a very small number of people who are unusually sensitive to air pollution. AQI between 101 and 150 is considered ‘unhealthy', and between 201 and 300 is said to be 'very unhealthy', while a reading of 301+ 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.
Dhaka has long grappled with air pollution issues. Its air quality usually turns unhealthy in the winter and improves during the monsoon. - UNB
