At 9:20 am, Dhaka had a score of 91 on the air quality index (AQI), placing it as the 13th worst city in the world.

A'moderate' AQI of 50 to 100 is regarded as having good air quality. However, a tiny minority of persons who are highly sensitive to air pollution may have a mild health issue.

The top three cities on the list were Seattle in the USA, Dubai in the United Arab Emirates, and Portland in the USA, with AQI ratings of 178, 173, and 168, respectively.

An AQI of 101 to 200 is regarded as "unhealthy," especially for vulnerable populations.

Similar to this, an AQI level between 201 to 300 is deemed "poor," while a result of 300 or more is "hazardous," offering significant health hazards to locals.

The AQI in Bangladesh is based on five criterion pollutants: ozone, NO2, CO, SO2, and particulate matter (PM10 and PM2.5).

Air pollution has always been a problem in Dhaka. One of the leading causes of mortality and disability globally continues to be air pollution.

As per the World Health Organization (WHO), air pollution kills an estimated seven million people worldwide every year.
