Dhaka’s air ranked fifth-worst in the Air Quality Index (AQI) on Sunday morning amid rising fears that the country could be hit by a second-wave of coronavirus.

Although the air of Bangladesh’s capital Dhaka marked a significant improvement on Wednesday morning, it was still classified as ‘unhealthy’ in the Air Quality Index (AQI).   Dhaka had an AQI score of 135 at 10:17am. It stood 20th in the list of cities with worst air.

Bangladesh’s capital Dhaka ranked seventh worst in the Air Quality Index (AQI) on Sunday morning.   It had an AQI score of 163 at 09:37am. The air was classified as ‘unhealthy’.   Thailand’s Chiang Mai and Saudi Arabia’s Riyadh occupied the first and second spots in the list of cities with worst air quality with AQI scores of 362 and 171 respectively.   When the AQI value is between 151 and 200, every city dweller, particularly members of sensitive groups, may begin to experience adverse health effects.   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 has long been grappling with air pollution. Its air quality usually improves during monsoon.
