The general objectives of this study are to investigate the fate and transfer of hydrophobic organic contaminants in estuarine environments. The compounds studied are legacy contaminants (PCB, PFOS, HBCDD) and of emerging concern (PFASs). The transfer of these different compounds is apprehended both from a trophic point of view (juvenile sole and their prey) and from a population point of view (monitoring in different age classes). Finally, the evaluation of potential biological dysfunctions in juvenile sole is also carried out by a multi-marker approach of chemical stress (performance of individuals and fitness of the population).

Main Results:

 The project developed new knowledge related to:

  • The state of contamination of the different compartments of the nursery;
  • Biomagnification in the estuarine food web of the sole;
  • The overall health status of juvenile and subadult sole;
  • Toxicokinetic modeling of trophic transfer and growth;
  • Modeling of the population dynamics of sole in the Channel.
