Etude du comportement geochimique du fer dans l'estuaire de la Seine ArchiMer
Guegueniat, P; Boust, D; Gandon, R; Hemon, G; Phillipot, J; Sanchez, J; Marin, P; Pieri, J.
This paper reports the study of iron geochemical behavior by the measurement of total iron, iron associated with mineral coat, and ratio FEII/FEIII. The results of total iron are exploited by normalisation with regard to aluminium and scandium.

Pouvoir complexant des eaux de l'estuaire de la Seine ArchiMer
Fischer, J; Wartel, M; Guegueniat, P; Gandon, R.
Copper has been studied, by the authors, owing to its ability to complex with various organic ligands of natural waters. Metals extraction and liberation can be explained, in part, by this complexing capacity.

Mineral and organic soluble forms of zinc, iron and copper: Distribution in the Seine Estuary. ArchiMer
Gandon, R; Guegueniat, P; Fischer, J; Wartel, M.
One characteristic of the Seine Estuary system is the process of sediment resuspension by the specific hydrodynamics of this environment. It's the main factor of trace metals transport. Autotrophic activities also have an effect on the estuary, by pH variation. The behavior of soluble and organic copper, iron, have been studied in relation to salinity in and out of the estuary. The results are compared with those of other estuaries.
Tipo: Text Palavras-chave: Hydrodynamics; Physicochemical properties; Water properties; Dissolved organic matter; Biogeochemical cycle; Resuspension; Metals; Suspended particulate matter.
