Assessment of bioremediation potential of metal contaminated soils (Cu
Metal BSAFs ranked as Cd > Zn > Cu and Pb (Table 1, P < 0.05), which was consistent with the result of Dai et al. (2004). The Cd accumulated in earthworm tissues would re-enter the soil when earthworm dies, posing environmental risk (Zhang et al., 2016). Therefore, it is important to reduce Cd accumulation in earthworm tissue.
