Platform M&M’s
The ‘Major and Trace Metals’ (M&Ms) platform brings together the cutting-edge analytical resources of the EPOC laboratory’s Aquatic Ecotoxicology (EA), Geochemical Transfers of Metals at the Continent-Ocean Interface (TGM) and Palaeoclimates (PALEO) teams. The M&Ms analytical platform has been awarded the Fédération des plateformes de l’Université de Bordeaux (FED) label and has joined the CNRS REGEF (Réseau Géochimique et Expérimental Français) network.
The platform specialises in the quantification of major elements and classic and emerging trace metals in various matrices: sediments, water, aquatic organisms and carbonates. The platform provides technical support for the geochemical and ecotoxicological characterisation of terrestrial and marine aquatic ecosystems, as well as for palaeoclimatic reconstructions.

Emilie Dassié and Yann Combes
haracterisation of metal bioaccumulation levels in aquatic organisms (molluscs, fish) using ICP OES and ecotoxicological impacts (mercury contamination in French Guiana).
Emilie Dassié and Thibault Caley
Determination of major elements by ICP OES and analysis of elemental ratios (Mg/ Sr/Ca, Li/Ca) in carbonates e g foraminifera corals, speleothems by ICP OES.
