Dhaka's air was unhealthy for sensitive groups on Thursday morning.

With an Air Quality Index (AQI) score of 111 at 9am, Dhaka ranked 10th on the list of cities worldwide with the worst air quality.

Pakistan's Lahore, India's Delhi and the Democratic Republic of the Congo’s Kinshasa occupied the first, second and third spots on the list, with AQI scores of 219, 190 and 172, respectively.

When the AQI value for particle pollution is between 101 and 150, air quality is considered unhealthy for sensitive groups, between 150 and 200 is unhealthy, between 201 and 300 is said to be very unhealthy, while a reading of 301+ is considered hazardous, posing serious health risks to residents.

The AQI informs people how clean or polluted the air of a city is and what associated health effects might be a concern for them.

The AQI in Bangladesh is based on five 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.

Per the World Health Organization (WHO), air pollution kills an estimated seven million people worldwide every year, mainly due to increased mortality from stroke, heart disease, chronic obstructive pulmonary disease, lung cancer and acute respiratory infections.
