Abstract
The ability of aquatic plants to absorb, translocate and concentrate metals has led to the development of various plant-based
treatment systems. The potential to accumulate metals like iron, nickel, manganese and copper by Trapa bipinosa was assessed by
subjecting them to different effluent concentrations of pulp and paper industry under laboratory conditions. Trapa showed the ability to
accumulate substantial amounts of the metals during a short span of one week. When the plants were grown in different concentrations they
caused significant reduction in various parameters like dissolved oxygen, biological oxygen demand, chemical oxygen demand, total
alkalinity, total hardness, chloride and sulphate. While there was an increase in biomass, no visible phytotoxic symptoms were shown by
treated plants.
