Abstract (EN): Relations between several stress oxidative biomarkers and aromatic polycyclic hydrocarbon (PAH) concentrations have been studied in wild sole, Solea senegalensis collected in the vicinity of a petrochemical industry. Antioxidant enzyme activities in eco-toxicological studies constitute excellent markers for exposure to a large variety of pollutants. The 16 PAHs in sediment as well as oxidative damage (LPO), activity of catalase (CAT), glutathione peroxidase (GPx), glutathione S-transferase (GST), glutathione reductase (GR) and PAHs type metabolites in sole liver were analysed. Significant correlations (p < 0.05) were established between some biomarkers as GST, GPx and CAT and PAHs metabolites in liver (naphthalene, pyrene and phenanthrene) and PAHs concentrations in sediments (fluoranthene, acenaphthene, anthracene and chrysene). PAHs accumulated in the sediment and organisms are inducers of antioxidant defences. GST, GPx and CAT were robust biomarkers showing correlations with both PAHs in sediments and liver PAH metabolites showing different responses to low and high molecular weight PAHs.
