Partner 6. EPOC (UMR 5805 CNRS-UBordeaux)
EPOC - Environnements et Paléoenvironnements Océaniques et Continentaux, is a multidisciplinary
laboratory, represented in this project by the "Transferts Géochimiques des Métaux" (TGM; 2 PR, 1
MDC, 2 IE) team working on Geochemistry and Ecotoxicology of metals in aquatic systems.
EPOC-TGM has performed internationally recognized research on trace metal cycles (e.g. sources and fate, reactivity, speciation, bioaccumulation, etc.) in complex natural aquatic systems. Coupling aquatic geochemistry and ecotoxicology implies the development of new experimental methods (in-situ and laboratory), based on high performance analytical techniques (e.g. operational and molecular metal speciation, incubations with stable isotopes, modelling) and the related equipment (e.g. clean rooms, GC-ICP/MS).
Cécile Bossy and Lionel Dutruch are specialized in speciation analyses of metals in natural samples by ICP/MS. Gérard Blanc and Jörg Schäfer have already successfully (>5 publications, 2 in prep.) collaborated with LCPME and GET members (Partners 3 and 5), e.g. on stable Hg isotopes in sediments and Hg methylation kinetics/potential of biofilms and plankton microbia. Experienced in Hg biomethylation in tropical and temperate systems, the team is highly motivated by contributing their specific competences to this project.
