Dhaka still continues to rank among the most polluted city in the world.
On Thursday, the Bangladesh capital ranked third in the US Air Quality Index.
The air quality index shows Dhaka scored 233 at 9am, classified as “very unhealthy.”
The index was developed by Environmental Protection Agency for reporting daily air quality of cities and countries all over the world.
Pakistan’s Lahore and India's Mumbai held the two top spots with individual scores of 377 and 265 respectively, according to data obtained from AirVisual, a smartphone application that shows real-time air pollution index.
Bangladesh, one of the most densely-populated countries in the world, has been grappling with the air pollution for quite a long time, with Dhaka always ranking among the most polluted cities.
Brick kilns, vehicles run by fuels with high-level sulphur, and construction work have been identified as the major causes of air pollution in Dhaka.
The air quality further declines during the dry season (from October to April). It improves slightly in the monsoon.
Voicing their deep concerns over environmental impacts of air pollution, experts said five of the top 10 causes of death in the country are related to air pollution.
