Abstract
Repeated use of Cu based fungicides (Bordeaux mixture: Ca(OH)2+CuSO4) to control vine downy hasled to signi!cant increase of Cu in vineyard soils. In Mediterranean catchments, brief and intense flood events can multiply stream discharge by up to 10 and are responsible for important soil leaching and therefore for high "uxes of Cu exported at the outlet of the catchment. In order to assess the origin and fate of Cu measured in the Baillaury catchment (South of France, combined sequential extraction (SCE) and isotopic Cu compositions (δ65Cu) approaches are proposed in this study.
