Air pollution: Dhaka occupies first position in Saturday’s AQI
The densely populated capital of Bangladesh continues to dominate the list of world cities with the worst air quality. On Saturday, Dhaka occupied the first position in the list. The city of Beijing in China occupied the second place. The third and fourth spots were grabbed by Kathmandu of Nepal and Delhi of India, respectively. Dhaka’s air quality index was recorded at 237 around 2:00am, which is considered ‘very unhealthy’. An AQI between 201 and 300 is considered ‘poor’, while a reading of 301 to 400 is said to be ‘hazardous’, posing serious health risks to city 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.
