Hepatic and branchial xenobiotic biomarker responses in Solea spp. from several NW Mediterranean fishing grounds
چکیده انگلیسی


• Solea solea and Solea senegalensis are good flatfish sentinels in Southern Europe.
• Gill biomarkers are also sensitive to pollution gradients.
• A multibiomarker approach using different target tissues is advisable.
• Higher AChE sensitivity to pesticides can be neutralized by higher CbE protection.

The common sole, Solea solea and the Senegalese sole, Solea senegalensis are two important commercial benthic species that coexist in the NW Mediterranean Sea. Several common biomarkers of chemical exposure were measured in two organs (liver and gills) involved in a different degree in biotransformation and detoxification processes. These parameters were: phase I cytochrome P450 CYP1A-dependent ethoxyresorufin O-deethylase and carboxylesterase activities, phase II glutathione S-transferase activity and the enzymatic antioxidants: catalase, glutathione reductase and glutathione peroxidase. Principal Component Analysis (PCA) considering biometric variables (size and weight) and all liver and gill biomarkers discriminated at a certain extent individuals of both species collected at the different fishing grounds. Esterase inhibition by the organophosphorus pesticides dichlorvos and diazinon was also compared in vitro in muscle, liver and gill of the two species revealing a differential sensitivity. The use of benthic sole in pollution monitoring of Southern Europe is discussed as local sentinel in respect to other benthic fish from more Northern latitudes.
