摘要：

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 results.
