Les PCB dans l'environnement marin. Aspects géochimiques d'apports et de distribution. Cas du littoral français

Abstract: Les PCB représentent un groupe de substances chimiques chlorées particulièrement rémanent dans l'environnement. La production mondiale cumulée est évaluée à 1 200 000 tonnes et environ 30 % de cette production sont dispersés dans l'environnement, essentiellement dans le milieu océanique. La distribution de ces substances dans l'environnement aquatique est fonction des mécanismes d'échanges aux interfaces eau/atmosphère, eau/sédiment, aux processus de transformation abiotiques et biotiques, et aux processus de … Show more

“…The preliminary analysis of PCBs in Seine River basin fish revealed fish contamination [42]. The mussel watch established since 1979 in the estuary by Ifremer confirmed an extreme contamination by PCBs, when compared to other French and foreign estuaries [81]. However, this issue could not be handled at the level of a single river basin.…”

“…In 1972 these compounds were included on the blacklist of UNESCO's International Oceanographic Commission and, in turn, on the list of products to be carefully monitored in French estuaries and river basin outlets [51]. Marchand [81] stated that the Seine estuary sediments had the highest contamination in PCBs with regard to all other French study sites.…”

“…the Marne River) (Chevreuil and Granier, 1991;Ollivon et al, 2002) or the Seine estuary (Abarnou et al, 1987;Marchand, 1989;Van Metre et al, 2008). Regarding the latter, only the works of Van Metre et al (2008) have focused on sedimentary archives downstream of the estuary; however, contamination sources in this area appear to be intra-estuarine.…”
