Le dispositif « SELI » est mis en place depuis 2016 pour acquérir des données sur les effets biologiques intégrateurs de la contamination chimique chez des organismes marins (poissons et bivalves) et ainsi renseigner le critère 2 du descripteur 8 de la DCSMM (Le niveau de concentration des contaminants ne provoque pas d’effets dus à la pollution). Le présent rapport concerne le volet SELIseine. Des poissons plats (194 soles, flets et limandes) ont été prélevés en septembre 2018 sur le N/O Antéa, et des moules ont été prélevées en février 2019 sur 6 stations dans le cadre du suivi ROCCH MV suivant le protocole de la convention OSPAR (2012). Les biomarqueurs suivis chez ces organismes couvrent plusieurs types d’effets toxiques (reprotoxicité, génotoxicité,... |

Des soles ont été prélevées en août et septembre 2017 et des moules en février 2018, dans le cadre du suivi ROCCH MV. Les biomarqueurs suivis chez ces organismes couvrent plusieurs mécanismes d’actions toxiques (reprotoxicité, génotoxicité, neurotoxicité) et incluent des mesures de la santé générale de l'organisme. Les contaminants suivis sont des éléments traces métalliques et des contaminants organiques... |

Albacore tuna (Thunnus alalunga) is a highly commercial fish species harvested in the world's Oceans. Identifying the potential links between populations is one of the key tools that can improve the current management across fisheries areas. In addition to characterising populations' contamination state, chemical compounds can help refine foraging areas, individual flows and populations' structure, especially when combined with other intrinsic biogeochemical (trophic) markers such as carbon and nitrogen stable isotopes. This study investigated the bioaccumulation of seven selected trace metals – chromium, nickel, copper (Cu), zinc (Zn), cadmium (Cd), mercury (Hg) and lead – in the muscle of 443 albacore tunas, collected over two seasons and/or years in the... |

Brominated flame retardants (BFRs) were investigated in juvenile common sole from nursery zones situated along the French coast in 2007, 2008 and 2009. Extensive identification was performed with regard to PBDEs, novel BFRs 1.2-bis(2,4,6-tribromophenoxy)ethane (BTBPE) and decabromodiphenylethane (DBDPE), and other non-PBDE BFRs, namely, hexabromobenzene (HBB) and 2,2',4,4',5,5'-hexabromobiphenyl (BB-153). Polybrominated diphenyl ether (PBDE) concentrations (E 14 congeners) ranged from 0.01 ng/g to 0.16 ng/g wet weight (ww) in muscle, and 0.07 ng/g to 2.8 ng/g ww in liver. Concentrations were in the lower range of those reported in the literature in other European locations. Lower PBDE concentrations, condition indices and lipid contents were observed in... |

An investigation was carried out into the PAH chemical contamination resulting from the "Erika" tanker fuel spillage of December 1999 along the French coast of the Bay of Biscay. A qualitative and quantitative assessment was conducted of this contamination in water, suspended particulate matter, sediments, and in intertidal molluscs. The chemical composition of PAHs in pre-spill and post-spill samples was determined and used to distinguish the "Erika's" fuel as the source of PAHs in the coastal environment of the Bay of Biscay. Changes in concentrations of PAHs were also assessed. The GC-MS analysis made it possible to identify and quantify parent unsubstituted PAHs, alkyl-substituted PAHs (C-PAH) and sulfur heterocycle unsubstituted and alkyl substituted... |

The uptake and elimination of six PBDE congeners (BDE-28, -47, -99, -100, -153, -209) were studied in juvenile common sole (Solea solea L) exposed to spiked contaminated food over a three-month period, then depurated over a five-month period. The results show that all of the studied PBDEs accumulate in fish tissues, including the higher brominated congener BDE-209. Several additional PBDE congeners were identified in the tissues of exposed fish, revealing PBDE transformation, mainly via debromination. The identified congeners originating from PBDE debromination include BDE-49 and BDE-202 and a series of unidentified tetra-, penta-, and hepta- BDEs. Contaminant assimilation efficiencies (AEs) were related to their hydrophobicity (log K-ow) and influenced by... |

The uptake, elimination and transformation of six PBDE congeners (BDE-28, -47, -99, -100, -153, -209) were studied in juvenile common sole (Solea solea L) exposed to spiked contaminated food over a three-month period, and then depurated over a five-month period. Methoxylated (MeO-) and hydroxylated (OH-) PBDEs were determined in fish plasma exposed to PBDEs and compared to those obtained in control fish. While all MeO- and some OH- congeners identified in fish plasma were found to originate from non-metabolic sources, several OH- congeners, i.e., OH-tetraBDEs and OH-pentaBDEs, were found to originate from fish metabolism. Among these, 4 '-OH-BDE-49 was identified as a BDE-47 metabolite. Congener 4 '-OH-BDE-101, identified here for the first time, may be... |

Polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) are persistent organic pollutants that have been shown to affect fish life-history traits such as reproductive success, growth and survival. At the individual level, their toxicity and underlying mechanisms of action have been studied through experimental exposure. However, the number of experimental studies approaching marine environmental situations is scarce, i.e., in most cases, individuals are exposed to either single congeners, or single types of molecules, or high concentrations, so that results can hardly be transposed to natural populations. In the present study, we evaluated the effect of chronic dietary exposure to an environmentally realistic marine mixture of PCB and... |

Persistent organic pollutants (POPs), such as PCBs (polychlorinated biphenyls) and PBDEs (polybrominated diphenyl ethers), are lipophilic and tend to bioaccumulate in cellular membranes and fat. The accumulation of lipids in oocytes during vitellogenesis, and subsequently in the eggs, favors the accumulation of POPs, and may affect the development of embryos. The effects of dietary exposure to POPs in Common sole Solea solea were evaluated on early life stages (ELS): the survival of sole embryos and features of embryonic development were assessed until hatching endpoint and compared to that of the control. No embryonic development was observed in PBDE eggs while hatching occurred in both control and PCB groups. In addition, several developmental... |
