Green activists yesterday urged the authorities concerned to take immediate steps to properly control air pollution caused by dust in the capital and ensure punishment for people responsible.
They came up with the demand at a human chain organised in front of Jatiya Press Club.
Some 16 rights organisations including Poribesh Bachao Andolon (Poba) and Nagorik Odhikar Songrokkhon Forum (NASOF) organised the event to draw the attention of authorities concerned in this regard.
The speakers said Dhaka's dust menace is getting worse, especially in dry season, due to unplanned development projects, brick kilns and drain sludge kept on roads.
Their other demands include ensuring regular cleaning of streets, framing rules for mandatory covering of dusty construction materials during transportation and construction, and raising awareness among people.
