EFFECTS OF FOOD LIMITATION ON 9 METAL CONCENTRATIONS IN LIVER AND POLYCYCLIC AROMATIC HYDROCARBON METABOLITES IN BILE OF JUVENILE TURBOT (SCOPHTHALMUS MAXIMUS) PREVIOUSLY EXPOSED TO CONTAMINATED SEDIMENTS
International audience A 2-step experimental design was employed in the present study on juvenile turbot (Scophthalmus maximus): 1) juveniles were exposed for 26 d to 2 contaminated sediments and a reference one, and 2) they were transferred in clean seawater with clean sediment for 35 d, feeding fi...

International audience A 2-step experimental design was employed in the present study on juvenile turbot (Scophthalmus maximus): 1) juveniles were exposed for 26 d to 2 contaminated sediments and a reference one, and 2) they were transferred in clean seawater with clean sediment for 35 d, feeding fish once a day, twice a week, or once a week. Fish exposed to contaminated sediments presented a significant increase of hepatic Cd, Cu, and Pb concentrations compared with the reference condition after the 26-d exposure. Higher fluorescence signals of polycyclic aromatic hydrocarbon (PAH) metabolites were found in bile from turbot exposed to contaminated sediments for 26 d compared with reference.
