Ethoxyresorufin-O-deethylase activity and content of polycyclic aromatic hydrocarbon metabolites in bream Abramis brama L. and perch Perca fluviatilis L. from the Sutka River (Rybinsk Reservoir)

Abstract

This article presents the results of a comparative analysis of hepatic ethoxyresorufin-O-deethylase (EROD) activity and content of biliary polycyclic aromatic hydrocarbon (PAH) metabolities in bream Abramis brama L. and perch Perca fluviatilis L. from a region with background levels of organic xenobiotics. Statistically significant interspecific differences are revealed. The results of the study should be considered in studies on the effects of contaminants in fish.
