Dhaka’s air quality stays ‘unhealthy’ this morning

Air pollution still remains one of the top-most challenges for Bangladesh as Dhaka was ranked seventh most polluted city in the world with ‘unhealthy’ air quality on Thursday (1 December, 2022) morning.

Dhaka’s air quality index (AQI) score was 162 at 10:00am on Thursday.

An AQI between 201 and 300 is said to be ‘very unhealthy’, while a reading of 301 to 400 is considered ‘hazardous’, posing serious health risks to residents.

Pakistan’s Lahore, India’s Delhi and Mongolia’s Ulaanbaatar occupied the first three spots in the list, with AQI scores of 409, 284 and 193, respectively.

An AQI between 101 and 200 is considered ‘unhealthy’, particularly for sensitive groups.

In Bangladesh, the AQI is based on five criteria pollutants—Particulate Matter (PM10 and PM2.5), NO2, CO, SO2 and Ozone.
