Abstract

The effects of Cd and HCHs with single and combined forms on Cd and HCHs phytoavailability of Allium sativum L. were investigated. The results indicated that the coexistence of Cd and HCHs presented antagonistic interactions mostly, which might be partly due to the formation of Cd–HCHs complex, compared with single stress. The bioaccumulation of Cd and HCHs in plants depended largely on their concentrations applied in pot soils, and the phytoavailability of HCH isomers was in the sequence: δ- > γ- ≥ β- > α-HCH.
