Dhaka has been ranked third in the world for the worst air quality, with an AQI score of 260 recorded at 9:02 AM on Saturday. This level categorizes the air as 'very unhealthy,' indicating significant health risks for residents. Delhi and Lahore topped the list with alarming AQI scores of 872 and 790, respectively.

An AQI score between 151 and 200 is deemed 'unhealthy,' while scores from 201 to 300 fall into the 'very unhealthy' category, and anything above 300 is considered 'hazardous.' The AQI serves as an index to inform residents about the cleanliness of the air and potential health effects.

In Bangladesh, the AQI is calculated based on five pollutants: particulate matter (PM10 and PM2.5), nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), and ozone. Dhaka has faced persistent air pollution challenges, especially during winter months when air quality tends to deteriorate.

The current situation highlights a troubling trend, as Dhaka's air quality has remained unhealthy for two consecutive days. Residents are advised to take precautions, such as wearing masks and using air purifiers, especially during periods of high pollution.
