Abstract:- Heavy  metals Ni ,  As  , Hg , Pb , Cd   , Cu, , Zn, Cr act  as  effective  enzymes inhibitors  . The virons or carcinogenic metals with their tendency for chelation are associated with vitamins; protein and nucleic acid .These metals ions may replace the (ZnII, MgII ) from the normal enzyme system or nucleic acid and may alter the structure and function of genetic material resulting in the formation of cancer.  The author wishes to highlight phytoremediation and the medicinal benefits of water hyacinth an aquatic weed, along with synthesis of liquid organic fertilizer from Eichhorniacrassipes. Phytoremediation of nickel, copper, cadmium, zinc by Salviniamolesta, Spirodelapolyrhiza ,Eichhorniacrassipes from water offer good  alternatives. Metal   accumulation  by  microorganisms and algae environmental  scientists and engineers try  to utilize  this property  of   bio accumulation  for  monitoring   metal  pollution as  well  as   removal \ recovery  of   property  of   bio accumulation  for    metals  from   natural  and   waste waters .

Keywords:- Eichhorniacrassipes, Salviniamolesta, Spirodelapolyrhiza, ZnII, MgII.
