Campagne dédiée à l'évaluation des effets biologiques induits pas la contamination chimique en Baies de Loire et Vilaine. SELILOIRE 2017 ArchiMer
Mauffret, Aourell; Wessel, Nathalie; Akcha, Farida; Munschy, Catherine; Chouvelon, Tiphaine; Couteau, Jérôme; Briaudeau, Tifanie; Izagirre, Urtzi; Aminot, Yann; Pollono, Charles; Moisan, Karine; Olivier, Nathalie; Bely, Nadege; Crochet, Sylvette; Thomas, Bastien; Sireau, Teddy; Menard, Dominique; Burgeot, Thierry.
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). 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...

Classic and novel brominated flame retardants (BFRs) in common sole (Solea solea L.) from main nursery zones along the French coasts ArchiMer
Munschy, Catherine; Moisan, Karine; Tixier, Celine; Boulesteix, Lara; Morin, Jocelyne.
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...

Contamination of the Bay of Biscay by polycyclic aromatic hydrocarbons (PAHs) following the T/V "Erika" oil spill ArchiMer
Tronczynski, Jacek; Munschy, Catherine; Moisan, Karine; Guiot, Nadege; Truquet, Isabelle; Olivier, Nathalie; Men, Sophie; Furaut, Audrey.
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...

Dietary exposure of juvenile common sole (Solea solea L.) to polybrominated diphenyl ethers (PBDEs): Part 1. Bioaccumulation and elimination kinetics of individual congeners and their debrominated metabolites ArchiMer
Munschy, Catherine; Moisan, Karine; Tixier, Celine; Olivier, Nathalie; Gastineau, Olivier; Le Bayon, Nicolas; Buchet, Vincent.
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...

Dietary exposure of juvenile common sole (Solea solea L.) to polybrominated diphenyl ethers (PBDEs): Part 2. Formation, bioaccumulation and elimination of hydroxylated metabolites ArchiMer
Munschy, Catherine; Moisan, Karine; Tixier, Celine; Pacepavicius, G.; Alaee, M..
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...

Etude des zones côtières exposées à la contamination par les produits phytosanitaires ArchiMer
Tronczynski, Jacek; Moisan, Karine; Bocquene, Gilles; Maggi, Pierre; Grizon, James.
Le présent rapport est relatif aux travaux effectués à la Direction de l'Environnement et de l'Aménagement du Littoral dans le Département des Polluants Chimiques (DEUPC) au Centre de I'IFREMER à Nantes. Cette étude a été réalisée dans le cadre de l'activité de la Cellule Régionale d'Étude des Pollutions Chimiques des Eaux par les Produits Phytosanitaires (CREPEPP) des Pays de la Loire. Un premier sondage de la contamination des eaux et des sédiments par les produits phytosanitaires et les mesures de l'activité des cholinestérases dans les mollusques marins a été effectué sur deux zones conchyliennes de la région des Pays de la Loire : la baie de l'Aiguillon et la Baie de Bourgneuf. Les objectifs spécifiques proposés ont été les suivants : + Réaliser un...

Mutagenicity and genotoxicity of suspended particulate matter in the Seine river estuary ArchiMer
Hubert, Francoise; Moisan, Karine; Munschy, Catherine; Tronczynski, Jacek.
Highly mutagenic compounds such as some PAHs have been identified in surface waters and sediments of the Seine river estuary. Suspended particulate matter (SPM) represents a dynamic medium that may contribute to the exposure of aquatic organisms to toxic compounds in the water column of the estuary. In order to investigate major sources of mutagenic contaminants along the estuary, water samples were taken at 25 in downstream of the outlet of an industrial wastewater-treatment plant (WWTP). SPM samples were analyzed for their genotoxicity with two short-term tests, the Salmonella typhimurium mutagenicity assay (TA98 + S9 mix) and the comet assay in the human HepG2 cell line. Sampling sites receiving effluents from a chemical dye industry and WWTP showed the...

PCDD/F, PBDE, and nonylphenol contamination in a semi-enclosed bay (Masan Bay, South Korea) and a Mediterranean lagoon (Thau, France) ArchiMer
Hong, Sang Hee; Munschy, Catherine; Kannan, Narayanan; Tixier, Celine; Tronczynski, Jacek; Moisan, Karine; Shim, Won Joon.
Chemical contamination of the coastal marine environment by polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) was assessed along with emerging contaminants such as polybrominated diphenyl ethers (PBDEs) in an industrially well-developed country (France) and a fast-developing country (Korea). Other chemicals, i.e. nonylphenol (NP) and 5 beta(H)-cholestan-3 beta-ol (coprostanol) were determined to trace industrial waste and/or domestic inputs. These compounds were analyzed in coastal sediments and mussels in two enclosed coastal water bodies: Masan Bay (South Korea) and Thau lagoon (France). The overall levels of target organic contaminants were higher in Masan Bay than in Thau lagoon. The mean concentrations of 17 PCDD/Fs,...
