Dhaka's air quality “unhealthy” despite rain
Dhaka's air quality is still "unhealthy".
With an air quality index (AQI) score of 119 at 9:12am today (July 7, 2022), the capital of Bangladesh ranked seventh in the list of world cities with the worst air quality.
Indonesia's Jakarta, Saudi Arabia's Riyadh and Pakistan's Lahore occupied the first three spots, with AQI scores of 163, 158 and 151, respectively.
An AQI between 101 and 200 is considered "unhealthy", particularly for sensitive groups.
Similarly, an AQI between 201 and 300 is said to be "poor", while a reading of 301 to 400 is considered "hazardous", posing serious health risks to residents.
AQI, an index for reporting daily air quality, is used by government agencies to inform 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.
