Flow cytometry for the evaluation of chromosomal damage in turbot Psetta maxima (L.) exposed to the dissolved fraction of heavy fuel oil in sea water: a comparison with classical biomarkers
International audience Turbot Psetta maxima were exposed 5 days to the dissolved fraction of fuel oil number 2, then decontaminated over 30 days in clean sea water. Biliary metabolites and ethoxyresorufin-O-deethylase (EROD) activity were evaluated during and after the contamination. These results w...
