There has not been sewage and household dissipates did not stream into the Gulshan lake in a single day. Gulshan Lake, located Gulshan-Baridhara area was officially marked an Ecologically Critical Area (ECA) to save the water body from becoming pollution. And also to protect it from infringement which was declared before 12 years.
According to the grapevine trying to convince people that it was central to safeguard it for the ecology of Dhaka city, two giant signboards of the Department of Environment (DoE) of the government have been posted on either end of the lake since November 26, 2001.
Although there have been a lot of environmental law and organization but the Gulshan-Baridhara Lake continues to get more polluted day by day for not taking any steps from law implement departments, claimed environmental lawyer Rizwana Hasan.
Whatever, officials of DoE claimed that Dhaka Wasa and Dhaka City Corporation are trying to stop pollution in the Lake.
It’s important that Rajdhani Unnyan Kartripakhha (RAJUK) undertook a plan to build a 40 feet road along the eastern shoreline of the lake.
Incidentally, to survive any kind of life in a water body, the minimum standard required level of break up oxygen is six milligrams per liter. The ECA rule was established in the year 1999 under the Bangladesh Environment Protection Act, 1995.
There aretotal of 12 ECAs have been identified in the Bangladesh. These areas are Tanguar Haor, Hakaluki Haor and Marjat Baoris also need to be protected. Shores of the lake are used as dumping ground for city waste
The locality and government are
neglected to be responsible for the relentless degradation. As 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 robbering.
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
Researchers of The Department of
Environment (DoE) had been an alarming message on levels of DO in these rivers
after three months research. They have analysis on various samples of 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 Erpert
Dr Ahsan Uddin Ahmed over phone, he said to Bd Environment that “such a DO
merge amount in water poses severe a great threats to biodiversity and
hydro-ecology”. “Random dumping of waste has put the rivers in and around the
city in a blackout”.
Professor Mujibur Rahman of Bangladesh
University of Engineering and Technology (Buet) said that government ought to
shift the tannery diligence from the Hazaribagh, Dhaka.
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.
In view of carrying out a methodical and corresponding research on Climate Change Change matters, a new study institute titled “Center for Climate Change Study & Resource Utilization (CCCSRU)” has established at by the department of Applied Chemistry and Chemical Engineering of Dhaka University.
The center will be a self-determining, and non-profit research and training institute dedicated mainly to the energy, environment and climate change issues. To initiate, promote, sponsor and organize scientific study effort on the various dimensions of problems and issues pertaining to Fossil Fuels, Petroleum, Natural Gas and Coal – their rational utilization and clean and energy efficient processing technology, CO2 discharge reduction, Climate change and its mitigation, nano and membrane knowledge, Waste management, water and air pollution and its technology for treatment, Energy policy are the main objectives of the Center.
Incidentally, there are fifteen members in governing body with the Vice-Chancellor of the University as Chairman, Deans of numerous faculties, Chairmen and Professors of concerning Departments as members and Director of the Center as member-secretary will govern the Center. Department of Applied Chemistry & Chemical Engineering of the University professor Dr. Rafiqul Islam is the founder director of the center.
