    Ashik Rahman: The locality and government are neglected to be responsible for the relentless degradation. As a source of livelihood, communication, and heart of people in Dhaka had been determined to the Buriganga River but now it’s a major source of running the capital. This happens due to pollution and building illegal property by robbing. So, now Rivers in Bangladesh is in ‘Comatose’

    Along with Buriganga, Turag, Shitalakkhya, Balu and Bangshi is being a death trap for increasing pollution and also indiscriminate sand lifting. The minimal level of dissolved oxygen (DO) required for life to survive in these rivers do not have.

    Researchers of The Department of Environment (DoE) had been an alarming message on levels of DO in these rivers after three months of research. They have analysis on various samples of a chemical whose were collected from these rivers and the levels of DO in Buriganga, Turag and Bangshi were 0.38, 0.59 and 0.0 milligram per liter gradually.

    According to the Environment Protection Act (Amendment) 2010, the minimum required level DO is 5 mg/l for any water body to sustain aquatic species including fishes and others is. The minimal standard rate for water being eligible for treatment as drinking water is 6 mg/l.

    Contacted with Environment Expert Dr Ahsan Uddin Ahmed over the phone, he said that “such a DO merge amount in water poses severe great threats to biodiversity and hydro-ecology”. “Random dumping of waste has put the rivers in and around the city in a blackout”.

The chemical waste from the tanneries is a major polluter of these rivers. It’s important that The DoE research had been found that the level of DO at the Hazaribagh area of Buriganga River was 1.06, 0.50 and 1.0 mg/l in January, February and March gradually. And the Bio-Chemical Oxygen Demand (BOD) is also very high in these waters.
