Resumo: | The study of Cd and Hg distribution in the sediments, water and suspended matter of the Bay of Marennes-Oléron provided the opportunity to identify the factors governing the distribution of these two contaminants throughout the bay. On one hand, these elements are associated with the continental inputs from the Charente river which settle on arrivaI at the mouth of the estuary and in the eastern part of the bay. The Cd and Hg present in these deposits are associated with POC, as weIl as with Mn and Fe oxides and hydroxides. On the other hand, a portion of the dissolved inputs is recycled in the bay waters through phytoplankton activity. This mechanism contributes, particularly in the case of Cd, to increased particulate metal fluxes from the water column to the sediment.
