As shown in the Table 1-2 and Fig. 2, the distribution of metals among water, soils and plants in different sample sites showed a similar trend as the following: soils >plants >water. The bioaccumulation factors (BCFs) that the ratio of metal concentration in the plants to that in the soils were calculated and listed in Fig. 3. The BCFs for different metals in the two plants were in the following order: Cd >Zn >Cu >Ni >Cr >Pb.
The correlations of metals among the water, soils and plants were analyzed in our study. The correlations between the soils and water, plants and water were not obvious. There were also no significant correlations between
