Dhaka, Nov 25 - Dhaka, the overcrowded capital city of Bangladesh, has ranked 4th on the list of cities with the worst air quality with an AQI index of 207 at 9:04 am on Saturday. 

Dhaka’s air was classified as ' very unhealthy', according to the air quality and pollution city ranking. 

India's Delhi, Pakistan’s Lahore and India’s Kolkata occupied the first, second and third spots in the list, with AQI scores of 389, 239 and 225, respectively. 

When the AQI value for particle pollution is between 101 and 150, air quality is considered ‘unhealthy for sensitive groups’, between 150 and 200 is ‘unhealthy’, between 201 and 300 is said to be 'very unhealthy', while a reading of 301+ is considered 'hazardous', posing serious health risks to residents. 

The AQI, an index for reporting daily air quality, informs people how clean or polluted the air of a certain city is and what associated health effects might be a concern for them. 

The AQI in Bangladesh is based on five pollutants: particulate matter (PM10 and PM2.5), NO2, CO, SO2, and ozone. 

Dhaka has long been grappling with air pollution issues. Its air quality usually turns unhealthy in winter and improves during the monsoon. - UNB
