Air Quality Index

Dhaka ranks 2nd worst

UNB, Dhaka

Bangladesh's capital Dhaka ranked second worst in the Air Quality Index (AQI) yesterday morning. It had an AQI score of 229 at 08:46 am. The air was classified as 'very unhealthy'.  Mongolia's Ulaanbaatar and Nepal's Kathmandu occupied the first and third positions in the list of cities with worst air quality. They had AQI scores of 275 and 212 respectively.  Everyone may experience more serious health effects when the AQI score is between 201 and 300.

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). The Department of Environment has also set national ambient air quality standards for these pollutants. These standards aim to protect against adverse human health impacts. Dhaka, the overcrowded capital of Bangladesh, has long been grappling with air pollution.
