Thursday at 8:25 a.m., Dhaka, the overpopulated capital of Bangladesh, topped the list of cities with the worst air quality, with an AQI index of 179.

According to the air quality and pollution city ranking, the air was categorized as "unhealthy."

Between 151 and 200, the AQI is considered "unhealthy," 201 to 300 is "very unhealthy," and 301 to 400 is "hazardous," posing severe health risks to residents.
Kuwait City, Kuwait, and Dubai, United Arab Emirates, ranked second and third, respectively, with AQI scores of 163 and 158, respectively.

The AQI, an index for reporting daily air quality, informs individuals as to how clean or polluted the air in a particular city is, as well as the health effects that may be of concern.

Bangladesh's AQI is calculated using five pollutants: particulate matter (PM10 and PM2.5), NO2, CO, SO2, and ozone.

Dhaka has long struggled with air pollution problems. Typically, its air quality declines during the winter and improves during the monsoon.

According to the World Health Organization (WHO), air pollution kills an estimated seven million people annually, primarily as a result of an increase in stroke, heart disease, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections.
