Metal enrichment was found to be dependent on the plant species and metal type. The uptake of copper, zinc cadmium, chromium and nickel from nutrient solutions enriched with these metals using Ottelia alismoides Pers., Fimbristylis pauciflora K. Br. and Blyxa malayana Ridley was studied.. All plants demonstrated the ability to remove copper, zinc and cadmium more rapidly than chromium and nickel. Metal accumulation was a direct function of the exposure level and varied with the plant species. The possible use of Ottelia alismodes and Fimbristylis pauciflora as biological indicators of water pollution is also discussed.
