The forest department has launched a field study in the affected Chandpai range of the Sundarbans to assess impacts of the oil spill on the mangrove forest.
The government, however, is yet to allocate funds for the study which would help the department take necessary steps to tackle the crisis.
Meanwhile, an official of the environment ministry said a UN team of experts is expected to visit Bangladesh very soon to assist the government in the clean-up of the oil spill.
A joint team of experts from the forest department, research cell of Khulna University and the Institute of Forest Research began working near Joymuni in Chandpai on Tuesday.
