Dissolved metals in surface waters

Interpreting fluxes of dissolved elements, especially trace metals, transported by rivers requires a precise knowledge of their numerous potential sources, both natural or anthropogenic. Identifying and quantifying the impact of these sources at various scales helps understanding fluviatil systems and, in fine, helps improving watershed management.

In collaboration with Tours University and the Loire-Bretagne Water Agency, we are coupling elemental concentrations and isotope compositions/ratios of dissolved Pb and Sr to characterise the geochemical background of the Loire River (France).
