The effects of Cd,Zn,Cu and Pb loads on fractions of the metals in five soils were studied,and buffer capacity of the soils to heavy metals was analyzed.The major fractions of heavy metals in the unpolluted soils were residual forms,which accounted for more than 51% of the total metals.With increasing loads of heavy metals in the soils,the proportions of metals as exchangeable form increased,those as residual form decreased,and thus increased availability of the metals and their impacts on the… CONTINUE READING
