MDA content, cell division , he activities of NR, CAT, POD and SOD of Pistia sagittifolia and Myriophyllum Spicatum with heavy metal,s ion concentration to appear a trend of ascending firstly and desending secondly . This trend explains that Pistia sagittifolia and Myriophyllum Spicatum on the Toxic Effects have similarities under handing the single Pb2+ and Hg2+. As the range of the concentration which each index is arriving at the maximum is different, this also indicates that there are some differences of the Toxic Effects between Pistia sagittifolia and Myriophyllum Spicatum under handing the single Pb2+ and Hg2
