Abstract
Phytoaccumulation is the process that introduces plant into environment and allow them to assimilate the contaminant into their roots and leaves. Such process has been used to clean-up heavy metals, pesticides, xenobiotics, organic compounds and acid mine drainage. Aquatic macrophytes are widely distributed in various wet environment from fresh to salt water and they play an important role in heavy metal cycling in the wet land due to uptake, storage and release processes in the form of phytoaccumulation. Phytoaccumulation is cost effective, environment friendly, aesthetically pleasing approach and most suitable for developing countries. In situ phytoaccumulation of metals from the water source by native aquatic and wetland plants selected for this research work are Aponogeton natans, Eichhornia crassipes, Lemna polyrrhiza, Pistia stratiotes, Scripus maritimus and Typha angustata. The SEM-EDX elemental analysis of in situ phytoaccumulation resulted in the maximum accumulation of chlorine 2.94%, sodium 2.29% and silica 1.52% by A. natans; E. crassipes accumulated 1.20% of potassium; L. polyrrhiza 4.93% of potassium, 4.59% of calcium, 2.25% of phosphorus, 2.17% of sulphur, 1.98% of chlorine, 1.75% of iron and 1.38% of magnesium; P. stratiotes accumulated 9.07% of silica, 2.04% of potassium, 1.30% of sodium; S. maritimus accumulated chlorine 1.82%, potassium 1.13%, calcium 1.04%, sodium 1.00% and 0.77% of fluorine; T. angustata accumulated 2.84% of chlorine, 1.56% of potassium and 0.92% of calcium.
