When the AQI value for particle pollution is between 101 and 150, air quality is considered 'unhealthy for sensitive groups'. A reading between 151 and 200 is classified as 'unhealthy', while readings between 201 and 300 are considered 'very unhealthy'. A reading of 301 or above is classified as 'hazardous', posing serious health risks to residents.
The AQI, an index for reporting daily air quality, informs people how clean or polluted the air in a city is and what associated health effects may be a concern.
The AQI in Bangladesh is based on five pollutants: particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulphur dioxide (SO2) and ozone.
Dhaka has long been grappling with air pollution. Its air quality usually becomes unhealthy in winter and improves during the monsoon.
