摘  要:
Two series of soil subsamples, by spiking copper (Cu), lead (Pb),zinc (Zn) and cadmium (Cd) in an orthogonal design, were preparedusing red soil and brown soil, respectively. The results indicatedthat heavy metal fractions in these soil subsamples depended not onlyon soil types, but also on metal loading quantity as well as oninteractions among metals in soil. Lead and Cu in red soil appearedmostly in weakly specifically adsorbed (WSA), Fe and Mn oxides bound(OX), and residual (RES) fractions.
