A brief review on pollution and ecotoxicologic effects on Sundarbans mangrove ecosystem in Bangladesh

The natural ecosystem of the Sundarbans mangrove wetlands is under threat due to anthropogenic activities. This ecosystem has become vulnerable to pollution such as oil spillage, heavy metals, and agrochemicals – which may have changed the mangrove ecosystem's biogeochemistry. In this paper, the present status of Sundarbans' mangrove pollution is reviewed. The ecotoxicologic effect on its aquatic and terrestrial flora and fauna, and pollution management problems are also discussed. Conservation and environmental pollution management for protecting this world's largest mangrove ecosystem are immediately needed. Environmentally sound technology should be adapted for pollution prevention, control and remediation in the Sundarbans mangrove wetlands.
