摘要：In areas with a high geological background of heavy metals,some edible plants could pose a serious threat to human *** order to find effective methods to remove heavy metals or reduce their harm,this study investigated the enrichment conditions of five soil heavy metals,Cd,Pb,Cu,Zn and Cr,in four edible plants in a mining area,Baoshantao,in eastern China that has a high geological background of metals,and two groups of experiments were designed to investigate the effects of passivators on their *** results showed that the soil heavy metal content in the study area has a certain degree of spatial *** five heavy metal element contaminants in the soil are in the order of Cd>Cu>Zn>Pb>*** enrichment coefficients and the transfer coefficients of different edible plants were different for the different heavy *** two groups of passivators showed better passivating effects with an increase in passivating agent *** smaller the enrichment coefficient of water spinach,the lower the *** results of this study can provide a scientific basis for the restoration of soil heavy metal pollution and the safe use of land in areas with a high geological background of heavy metals.
