| 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... |
