Abstract
The Gangetic delta, at the apex of Bay of Bengal is recognized as one of the most diversified and productive ecosystems in the Indian subcontinent. The deltaic lobe is unique for its wilderness, mangrove gene pool and tiger habitat. However due to intense industrial activities in the upstream zone, and several anthropogenic factors, the western part of the deltaic complex faces pollution from domestic sewage and industrial effluents leading to serious impacts on biota. The presence of Haldia port-cum-industrial complex has accelerated the pollution problem with a much greater dimension. The organic and inorganic wastes released from industries and urban units contain substantial concentrations of heavy metals. The present paper aims to highlight the level of selective heavy metals (Zn, Cu and Pb) in the muscles of five commercially important species of finfish collected from the aquatic subsystem in two sectors (western and central) of Indian Sundarbans during March 2008. The heavy metals accumulated in the fish muscles in the order Zn > Cu > Pb. Significant spatial variations of heavy metal concentrations in fish muscles were observed between the selected stations, which reflects the adverse impact of industrialization and urbanization on the fish tissue.
