Dhaka ranks fourth in Air Quality Index

Dhaka ranks fourth in Air Quality Index

Dhaka’s air quality continued to be in the 'unhealthy' zone on Saturday morning.

With an air quality index (AQI) score of 160 at 9am, the metropolis ranked fourth in the list of world cities with the worst air quality.

Pakistan’s Lahore and Karachi and China’s Wuhan occupied the top three spots in the list, with AQI scores of 180, 169 and 161, 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.
