‘No improvement in sight’

Dhaka, one of the most densely populated cities in the world, has been grappling with air pollution for a long time. The air quality generally worsens during summer and shows signs of improvement in monsoon when the dust settles.

Environment, Forests and Climate Change Minister Md Shahab Uddin had admitted that the air pollution in Dhaka reached an intolerable level while the High Court issued a nine-point directive to bring down air pollution in the capital.

In an interview with UNB, he said brick kilns were responsible for 58 percent air pollution in the capital.

He said the Department of Environment (DoE) and the World Bank published a research report on the sources of air pollution in Bangladesh in March last year which identified brick kilns, fumes of vehicles and dust from construction sites as three main sources.

On January 13, the High Court issued nine-point directive following a writ petition filed by Human Rights and Peace for Bangladesh (HRPB).
