Pot experiments were conducted to study the transfer and distribution of Cu, Zn, Pb and Cd in soil-swamp cabbage systems under both mono-pollution and multi-pollution conditions. The results showed that under both mono-pollution and multi-pollution conditions, bioconcentration factors (BCF) of the four metals in the stem and leaf of swamp cabbage appeared as Cd > Zn > Cu > Pb, but transport factors (TF) appeared as Cd > Zn > Pb > Cu. Compared with the mono-pollution condition, BCF of Cu, Zn, Pb and Cd decreased; under the multi-pollution condition, TF of Cu increased but TF of Zn, Pb, Cd decreased. Under the mono-pollution condition, BCF and TF of Cu decreased, BCF of Zn and Pb increased while TF decreased, and BCF of Cd increased but TF changed slightly with increasing heavy metal contents in the soil. In general, BCF of Zn, Pb, and Cd decreased obviously with increasing Cu content in soil under the multi-pollution condition; BCF of Cd decreased obviously with increasing Zn content in the soil; BCF of Cu increased obviously with increasing Pb content in the soil; and BCF of Pb increased obviously with increasing Cd content in the soil.
