  • Le chrome en milieu marin

    Auteurs :

    • Chiffoleau, Jean-francois

    text | Ifremer | 1994

    This document constitutes a synthesis of current knowledge on the chromium biogeochemical cycle. The natural and anthropogenic sources are evaluated, the fluxes between the various geochemical compartments are assessed, with speci...

  • Comportement chimique et geochimique des elements a l'état de traces dans l'estuaire de la Seine: Synthese des discussions

    Auteurs :

    • Guegueniat, P

    text | Actes de colloques. Ifremer. Brest [ACTES COLLOQ. IFREMER.]. 1986 | 1985-01-24

    In the synthesis of discussions about the chemistry of the Seine Bay, the author after a note on natural references for metal concentrations, speaks about fluorides, nutrients, PCB, and metallic elements. In conclusion some sugges...

  • Evolution de la complexation des metaux (Ca, Mg, Cd, Pb et Cu) dans l''estuaire de la Seine

    Auteurs :

    • Fischer, J
    • Wartel, M

    text | Actes de colloques. Ifremer. Brest [ACTES COLLOQ. IFREMER.]. 1986 | 1985-01-24

    Interaction between metallic ions and dissolved organic matter can take major part in the biogeochemical cycle of metals in the aquatic environment. The authors point out copper behavior by the study of complexing capacity of surf...

  • Pouvoir complexant des eaux de l'estuaire de la Seine

    Auteurs :

    • Fischer, J
    • Wartel, M
    • Guegueniat, P

    text | Actes de colloques. Ifremer. Brest [ACTES COLLOQ. IFREMER.]. 1986 | 1985-01-24

    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.

  • Dynamique hivernale des nutriments et du carbone dans les exutoires du Marais poitevin et flux terrestres associés en Baie de l’Aiguillon

    Auteurs :

    • Le Marchand, Marie

    text | 2017-06

      Coastal environments represent key systems in biogeochemical cycle couplings between continents, oceans and the atmosphere. Despite its relatively modest surface area (7 % of global ocean), this zone accounts for 14-30 % of...

  • Devenir de l'atrazine dans le bassin de Marennes-Oléron (France) - Approche par la modélisation hydrodynamique, hydrosédimentaire et biogéochlmique

    Auteurs :

    • Vanhoutte Brunier, Alice

    text | 2001

    Atrazine is the most widely used herbicide on cultured areas. This pesticide is degraded during its transport in rivers and streams, to the coastal area. Marennes Oleron is the main french oyster farming area, receiving the fresh ...
