title: Oxidative damage induced in Vicia faba by coke plant wastewater.
abstract: The present study investigated toxic impacts of coke plant wastewater over a concentration gradient of COD( Cr) 40-640 mg/l on malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) in roots and leaves of Vicia faba. MDA levels and SOD activities were significantly increased at all concentrations both in roots and leaves of Vicia faba; CAT and POD activities were significantly enhanced in roots at low concentrations and were significantly decreased at high concentrations (COD(Cr) 320 and 640 mg/l for CAT; COD( Cr) 640 mg/l for POD). In leaves, CAT and POD activities remained enhanced at all concentration and did not show significant difference at COD( Cr) 640 mg/l for CAT and COD(Cr) 40, 640 mg/l for POD. These results suggest that coke plant wastewater can cause oxidative damage in roots and leaves of Vicia faba and root enzymes seemed more sensitive to the wastewater.
