Abstract

In the current study, abnormal high levels of lead, cadmium, copper, zinc, iron, nickel and chromium were detected in Ismailia channel water. Significant elevation in the levels of such metals was observed in liver and musculature of Clarias gariepinus living in this area. Malondialdehyde and reduced glutathione concentrations as well as glutathione-S-transferase and superoxide dismutase activities were significantly increased in the liver of the fish while glutathione peroxidase and catalase activities were significantly decreased.
