Pesticides represent a major proportion of the chemical pollutants detected in French coastal waters and hence a significant environmental risk with regards to marine organisms. Commercially-raised bivalves are particularly exposed to pollutants, among them pesticides, as shellfish farming zones are subject to considerable pressure from agricultural activities on the mainland. The aims of this study were to determine (1) the genotoxic effects of diuron exposure on oyster genitors and (2) the possible transmission of damaged DNA to offspring and its repercussions on oyster fitness. To investigate these points, oysters were exposed to concentrations of diuron close to those detected in the Marennes-Oleron Basin (two 7-day exposure pulses at 0.4 and 0.6 μg...

Qualité sanitaire des gisements naturels de coquillages. Ille-et-Vilaine & Côtes d'Armor. Pêche à pied récréative. Année 2018 ArchiMer
Cheve, Julien; Pallud, Marie; Prigent, Jean-luc; Mercerie, David.
Le présent document dresse le bilan de la qualité sanitaire de l'ensemble des gisements naturels suivis par l'ARS Bretagne et l'Ifremer dans les départements des Côtes d'Armor et d'Ille-et-Vilaine, sur la période 2015-2017. Ce rapport s'inscrit dans le cadre du projet RESP²ONsable, mené par l'Ifremer et l'ARS Bretagne depuis 2013 sur la communication des risques sanitaires de la pêche à pied récréative. Son support principal est un site internet mettant à disposition du public une information complète et actualisée, à l'échelle de la Bretagne.
