Lahore in Pakistan and Kathmandu in Nepal occupy the top two spots in the list with AQI scores of 225 and 182 respectively.

An AQI score between 151 and 200 is considered 'unhealthy'. An AQI score of 201 to 300 is considered 'very unhealthy' and an AQI score of 301 to 400 is considered 'hazardous', posing a serious health risk to residents.

AQI in Bangladesh is determined based on five parameters of pollution, namely—Particulate Matter (PM10 and PM2.5), NO2, CO, SO2 and Ozone (O3).

Dhaka has been suffering from air pollution for a long time. Its air quality generally becomes unhealthy during winters and improves slightly during monsoons.
