Mise en évidence et validation de biomarqueurs écotoxicologiques dans la population d'anguilles d'un étang de la réserve naturelle nationale de Camargue, le Vaccarès, exposée à des polluants organiques persistants
International audience Though located in a rather remote area free from neighbouring industrial activities, the French National Nature Reserve of Camargue is however exposed to a non point source contamination by a number of persistant organic pollutants, particularly polycyclic aromatic hydrocarbon...

International audience Though located in a rather remote area free from neighbouring industrial activities, the French National Nature Reserve of Camargue is however exposed to a non point source contamination by a number of persistant organic pollutants, particularly polycyclic aromatic hydrocarbons (PAH) and organochlorine compounds (OC). Due to the nature of this contamination, investigations about validation of biomarkers in the eels of the Vaccarès lagoon have proven to be of the utmost importance. They have been focused on the characterization and validation of biomarkers related to metabolic responses including, not only the detoxification mechanisms (biotransformation, antioxidant process) and the energy requirements, but also some unspecific metabolic processes. These last ones are enzymatic membrane markers implicated either in the neuronal conduction (acetylcholinesterase, AChE) or in the osmoregulation and the energy metabolism (ATPases).
