| Air pollution in Dhaka |
Air quality in the capital was in the 'unhealthy' zone on Wednesday morning, UNB reported.
With an Air Quality Index (AQI) score of 166 at 8:41 am on Wednesday, Dhaka ranked second in the list of global cities with the worst air quality.
An AQI between 151 and 200 is considered 'unhealthy'.
Indonesia's Jakarta and Chile's Santiago occupy first and third place on the list with AQI scores of 173 and 157 respectively.
An AQI between 201 and 300 is said to be 'very unhealthy', while readings of 301 to 400 are considered 'hazardous', posing serious health risks to residents.
In Bangladesh, AQI is based on five criteria pollutants—particulate matter (PM10 and PM2.5), NO2, CO, SO2 and ozone.
Dhaka has been plagued with air pollution problems for a long time.
According to the World Health Organization (WHO), air pollution kills an estimated 7 million people worldwide each year, mainly as a result of increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer and acute respiratory infections.
