摘要: We evaluated the influence of biodegradable chelant ethylenediamine disuccinic acid (EDDS) on plant uptake polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and Cu by corn from electronic waste (e-waste)-contaminated soil. The highest concentration total in were observed treatment with 5 mM EDDS, which resulted a 4-fold increase translocation factor (C(shoot)/C(root)) compared to control. concentrations PCBs PBDEs shoots roots increased increasing application rates 1.58- 1.32-fold average increases PBDEs, respectively, EDDS treatments. A significant positive correlation was between shoot PBDEs. speculate that activated EDDS-triggered dissolved organic carbon (DOC) then indiscriminately taken up translocated following damage mainly extractable resulting application.
