Dhaka, the capital city of Bangladesh, experienced a concerning level of air pollution this morning, as indicated by an air quality index (AQI) score of 139 recorded at 9:10 am on June 6, 2023.
This ranking placed Dhaka as the 4th city with the most polluted air globally. Topping the list were Johannesburg in South Africa, Doha in Qatar, and Jakarta in Indonesia, with AQI scores of 166, 153, and 152, respectively.
When the AQI value falls between 101 and 150, the air quality is deemed “unhealthy for sensitive groups.” If it ranges from 151 to 200, it is classified as “unhealthy.” A reading between 201 and 300 indicates “very unhealthy” conditions, while a value exceeding 301 is considered “hazardous,” posing severe health risks to residents.
In Bangladesh, the AQI calculation incorporates five criteria pollutants, including particulate matter (PM10 and PM2.5), NO2, CO, SO2, and Ozone. Dhaka has long been grappling with air pollution issues, and it consistently ranks among the top risk factors for death and disability worldwide.
The elevated air pollution levels in Dhaka serve as a reminder of the urgent need to address this persistent problem. Efforts to mitigate pollution and improve air quality are crucial to safeguarding the health and well-being of the city’s residents.
