Dénombrement des coliformes thermotolérants ou des Escherichia coli dans des sédiments côtiers vaseux ArchiMer
Gourmelon, Michele; Derrien, A.; Crenn, Isabelle; Loaec, Solen.
Des bactéries fécales telles que les Escherichia coli ou les coliformes thermotolérants ont été recherchées dans des sédiments côtiers vaseux (prélevés sur deux sites différents: Morlaix et St Pol de Léon; Finistère). Ces vases, sous influence de rejets polluants, de par leur richesse en matière organique et en particules de faible taille sont susceptibles d'héberger ces bactéries. Une partie de l'étude a consisté à comparer différentes techniques de relargage des bactéries des particules de sédiment décrites dans la littérature.

Port activities require continuous or occasional dredging of considerable quantities of sediments : approximately 50 million m3 along the French coastline. A large proportion of the dredgings is authorized for dumping at sea in geographically delimited areas and following an impact evaluation of their potential harmfulness to the marine environment. The environmental risks assessment linked to dredging operations relies on knowledge related to several scientific disciplines contributing to changes in the regulations. This work, intended both for managers and for environmental scientists and engineers, is designed to take stock of the current state-of-the-art in the field of sediment contamination and related ecotoxicological hazards, along with a review of...
