Bangladesh capital Dhaka ranked as the third most polluted city in the world with ‘very unhealthy’ air quality on Friday morning, reports UNB.

Dhaka’s air quality index score was 207 at 9:50 am on Friday.

An AQI between 201 and 300 is said to be ‘very unhealthy’, while a reading of 301 to 400 is considered ‘hazardous’, posing serious health risks to residents.

Pakistan’s Lahore and Mongolia’s Ulaanbaatar occupied the first and second spots in the list, with AQI scores of 422 and 251, respectively.

An AQI between 101 and 200 is considered ‘unhealthy’, particularly for sensitive groups.

In Bangladesh, the AQI is based on five criteria pollutants -- Particulate Matter (PM10 and PM2.5), NO2, CO, SO2, and Ozone.

Dhaka has long been grappling with air pollution issues. Its air quality usually turns unhealthy in winter and improves during the monsoon.

Air pollution consistently ranks among the top risk factors for death and disability worldwide. Breathing polluted air has long been recognised as increasing a person’s chances of developing heart disease, chronic respiratory diseases, lung infections, and cancer, according to several studies.

As per the World Health Organization, air pollution kills an estimated seven million people worldwide every year, largely as a result of increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer, and acute respiratory infections.

The worsening air quality of Dhaka city is threatening the health status and life of its residents.
