Utilisation d’espèces halieutiques exploitées comme indicateurs de la contamination chimique en zone littorale

TL;DRAbstract

The concept of biological indicator relies upon the assumption that the contamination measured in biological tissues reflects that of the aquatic environment. This study aims to update the knowledge on contamination levels of various chemical contaminants in a few exploited fish species from various areas along the French coastline. The objective of the work is to evaluate the possibility of differentiating the various coastal zones according to the contamination levels measured in fish living there. Several groups of contaminants were followed: PCBs (marker PCBs and dioxin-like PCBs), dioxins (PCCDs and PCDFs), PBDEs, PFCs and total mercury). These contaminants were mainly measured in four fish species: the sea bass (Dicentrarchus labrax), the mackerel (Scomber scombrus), the red mullet (Mullus surmuletus) and the sardine (Sardina pilchardus). These fishes were collected in eight different areas along the French coasts, four in the English Channel, two in the Bay of Biscay and last on
