Dhaka’s air quality improves

Bangladesh’s capital Dhaka on Wednesday morning ranked 12th worst in the Air Quality Index (AQI).


The air in Dhaka was categorised as ‘moderate’ and the megacity had an AQI score of 80 at 09:07am.


When the AQI remains in between 51 and 100, there may be a risk for some people who may be unusually sensitive to particle pollution.


However, the air quality is acceptable.

Saudi Arabia’s Riyadh, Indonesia’s Jakarta and Iran’s Tehran occupied the first three spots in the list of cities with the worst air quality with AQI scores of 153, 137 and 119 respectively.


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.


In Bangladesh, the AQI is based on five criteria pollutants – Particulate Matter (PM10 and PM2.5), NO2, CO, SO2, and Ozone (O3).


Dhaka’s air starts getting fresh when rain starts from mid-June. The air remains mostly acceptable during the monsoon season from June to October.
