This morning, Dhaka's air quality remained in the "unhealthy" range.

The nation's capital was ranked second on a list of cities with the worst air quality in the world at 8:41am, earning an air quality index (AQI) score of 166.

An AQI of 151 to 200 is regarded as "unhealthy".

With AQI scores of 173 and 157, Jakarta and Santiago, Chile, respectively, were first and third on the list.

A reading of AQI between 201 and 300 is deemed "very unhealthy," while a reading between 301 and 400 is deemed "hazardous," posing significant health risks to locals.

The AQI in Bangladesh is based on five criteria pollutants: ozone, NO2, CO, SO2, and particulate matter (PM10 and PM2.5).

Air pollution has long been a problem in Dhaka.

According to the World Health Organization (WHO), air pollution kills an estimated seven million people annually throughout the world, primarily due to an increase in fatalities from heart disease, stroke, lung cancer, chronic obstructive pulmonary disease, and acute respiratory infections.
