To offer scientific basis for phytoremediation of heavy metal contaminated environment, the accumu- lation and distribution of heavy metals and the effect of exogenous materials on heavy metal accumulation in plants are reviewed in this paper by the method of studying relevant references. Analysis indicates that : (1) the accumulation and distribution of heavy metals in plants vary with the metal kinds, organ and cell of plants ; the combination of heavy metals in cell wall and compartment in vacuole are the main distribution forms;(2)the ...
