| 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... |

| Marine decapod crustaceans are macrobenthic opportunist species, of great commercial interest, and can accumulate pollutants. Worrying about consumers' safety, polychlorobiphenyls (PCBs), polybromodiphenyl Ethers (PBDEs) and dioxins (PCDD/Fs) were analyzed in four crustacean species from the coastal waters of Brittany and Normandy. As regards to regulations, the consumption of crustacean muscle doesn't raise any health problems. The second objective of this study was to evaluate the biological processes influencing PCB bioaccumulation in the spider crab Maja brachydactyla. From a quantitative point of view, organotropism, diet and age were the major factors acting on contamination. From a qualitative point of view, PCB fingerprints depended on sex, and to... |

| A rapid analytical method including one-single solid-phase extraction (SPE) procedure followed by gas and liquid chromatography coupled with high resolution mass spectrometry detection (GC-MS and LC-HRMS respectively) was developed for the quantification of 40 organic compounds (1.6 < log K-ow < 9.5) in seawater including both legacy and emerging contaminants, with a focus on the most common plastic organic additives. This new method allowed for the analyses of nine organophosphate esters (OPEs), seven phthalates (PAEs), six bisphenols (BPs), five perfluorinated compounds (PFCs), and thirteen legacy organochlorinated compounds (OCs, including polychlorobiphenyles and pesticides) with recoveries in the ranges of 57-124% for OPEs, 52-163% for PAEs,... |
