Dhaka’s air quality improves

Dhaka’s air quality has improved to ‘moderate’ level, reports UNB.

With an air quality index (AQI) score of 81 at 9.22 am, the metropolis ranked 17th on the list of world cities with the worst air quality.

Iran’s Tehran, the UAE’s Dubai, and South Africa’s Johannesburg occupied the first three spots, with AQI scores of 161, 154, and 149, respectively.

On Thursday, the city’s air quality was marked ‘unhealthy’ with an AQI score of 121 at 9am.

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.
