Abstract: The ultrastructural localization of Cd and Zn in leaf cells of Potamogeton crispus Linn. was studied with modified sulfide-silver method.Observation showed that Cd and Zn appeared in cell wall,cell membrane and tonoplast. Silver grains were also observed in chloroplast and certain vacuoles . The toxic mechanism of heavy metals was discussed based on the experimental ersults.
