The effects of Sublethal Concentrations of Chlorpyrifos on the Liver Enzyme Activities and Oxidative Stress Markers in Common Carp (Cyprinus carpio)

Chlorpyrifos is an organophosphate pesticide that is widely used to control the pests in agricultural fields. The aim of this study is to determine the effects of sublethal concentrations (0.1, 0.05 and 0.02 mg/l) chlorpyrifos on the liver enzymes activities and oxidative enzymes (superoxide dismutase and catalase) in common carp (Cyprinus carpio) on 1, 7, 14 and 21 days. The present results suggest that a significant increase in the activities aspartate aminotransferase (AST) and alanine aminotransferase (ALT) fish exposed to pesticide chlorpyrifos compared with a control group (P
