An AQI between 151 and 200 is said to be 'unhealthy' while 201 and 300 are considered 'very unhealthy,' and 301 to 400 are ranked 'hazardous,' posing serious health risks to residents.
In Bangladesh, the AQI is based on five criteria 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.
As per the World Health Organization (WHO), air pollution kills an estimated seven million people worldwide yearly, largely due to increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections.
