Vietnam’s Hanoi, Pakistan’s Lahore and India’s Delhi occupied the first three spots in the list of cities with the worst air quality with AQI scores of 182, 162 and 158 respectively.
 
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.
 
In Bangladesh, the AQI is based on five criteria pollutants – Particulate Matter (PM10 and PM2.5), NO2, CO, SO2, and Ozone (O3).
 
Dhaka has long been grappling with air pollution. Its air quality usually improves during monsoon.
