UNB :
Dhaka’s air quality remained ‘unhealthy’ on Thursday as the metropolis continued to dominate the list of cities with the worst air quality in the world.
On Thursday, Dhaka occupied the third position in the list as its air quality index (AQI) was recorded at 190 at 10am.
Pakistan’s Lahore and India’s Kolkata occupied the first two spots, with AQI scores of 228 and 194, 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.
