Industrial wastes are considered critical factors for dis-turbing the natural environment. Composite effluentstainted with different heavy metals are major environ-mental pollutants of varied wetland ecosystems (Wong2003). Spread over 12 500 ha, The East Calcutta Wet-lands, a Ramsar site in West Bengal, India (lat 22°33·Œ22°40·N, long 88°25·Œ88°35·E), receives industrial run-off from at least 6000 large- and small-scale industrialestablishments (including tanneries) and Calcutta metro-politan city wastewater throughout the year. The hugeamounts of composite, heavy-metal-contaminated efflu-ents (nearly 50 000 m
