Bangladesh's capital, Dhaka, was ranked third worst in Air Quality Index (AQI). Dhaka scored 197 at 9am, indicating that the city's air quality was unhealthy on Tuesday morning. 

Vietnam's Hanoi and India's Delhi were at the top of the list with scores of 245 and 199 respectively, reports UNB.

When the AQI value is between 151 and 200, every city dweller may begin to experience health effects. Members of sensitive groups may experience more serious health effects in this situation. 

Active children and adults, and people with respiratory diseases, such as asthma, are advised to avoid prolonged outdoor exertion. 

The air quality is categorized as good when AQI score remains between 0-50 while the air is moderate when AQI is 51 to 100 but when AQI is in between 101 and 150, it is classified as unhealthy for sensitive groups.  

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

 Bangladesh's overcrowded capital has been grappling with air pollution for a long time. The quality usually improves during monsoon.
