%X Nine kinds of hydrophyte and the corresponding water samples and sediments from  the East Lake of Wuhan were collected, and the concentrations of heavy metals (Cd, Zn, As, Cu, Co, Pb, Mn, Cr, Ni) in these samples were measured by microwave digestion-ICP-MS (Inductively coupled plasma mass spectrometry). Results indicate that the nine hydrophytes have some coherence in adsorbing heavy metals, and the order of these metals is Mn&gt;Zn&gt;Pb&gt;Cu&gt;Ni&gt;Cr&gt;As&gt;Co&gt;Cd. As for different parts of the hydrophytes, the adsorptive ability of root is the largest, followed by stem and leaf, and as for different kinds of hydrophytes, the adsorptive ability of submerged plant is the largest, followed by floating-leaved plant and emerged plant. The bioaccumulation factors of <i>ceratophyllum demersum</i>, duckweed and water hyacinth are large, so they can be used as remediation plant to purify the water contaminated by Mn, Zn, and Cd.<br/><br/>
