An oil spill from a crashed tanker is threatening endangered
dolphins and other wildlife in the Sundarbans mangrove region.
Bangladesh officials have called the leak an ecological
“catastrophe”.
The tanker, carrying an estimated 350,000 litres (75,000
gallons), of oil collided on Tuesday with another vessel and partly sank in the
Sundarbans’ Shela river, home to rare Irrawaddy and Ganges dolphins.
Although officials are unsure how much oil has spilled, they
warned the slick has spread to another river as well as a network of canals in
the vast Sundarbans delta.
“The oil spill has spread over a 60km-long (37 mile) area in
the Shela and Passur rivers,” said Amir Hossain, chief forest official of the
Sundarbans.
“It’s a catastrophe for the delicate ecology of the
Sundarbans. The oil spill has already blackened the shoreline, threatening
trees, plankton, vast populations of small fishes and dolphins,” Hossain said.
“The symptoms of environmental damage will be visible soon,
as the water quality has already been damaged,” he added.
Authorities have launched a small-scale clean-up, but warned
they lack the hardware and experience for a major effort. Navy boats and
government officials were en route to salvage the tanker.
“We’ve not started any major clean-up efforts yet. In fact,
the forest department doesn’t have the technology to deal with this kind of
disaster,” said Hossain.
Bangladesh’s state-run petroleum corporation was using buoys
to restrict the slick, while local fishermen have been ordered to use nets to
try to stop the oil entering small canals.

Spread over 10,000 sq km (3,900 sq miles), the Sundarbans is
a Uesco-listed World Heritage Site and home to hundreds of Bengal tigers. The
delta comprises a network of rivers and canals straddling Bangladesh and India.
The accident occurred inside one of three sanctuaries set up
for the dolphins, said Rubayat Mansur, Bangladesh head of the New York-based
Wildlife Conservation Society.
The three areas were declared dolphin sanctuaries in 2011
after studies found they are home to some 6,000 of the animals. Fishermen are
banned from making catches there, but tankers and other boats are allowed to
pass through.
Speaking to AFP from the accident site, Mansur labelled the
spill a “national disaster” and accused authorities of not doing enough to
contain the damage.
“There are no coordinated efforts to tackle the disaster.
The air has become toxic and we got news from fishermen they’ve seen dead
fishes. Crabs which make up the largest single group in the forest are facing
the biggest threat,” he said.
“And if crabs are hit, the dolphins and tigers will be
affected. Dolphins will find it very difficult to breathe this foul air,” he
added.
