Copper pollution in some vineyard soils of the Piedmont region (Italy): accumulation and mobility

0
Cu-based fungicides have been heavily used against the mildew caused by Plasmopara viticola, widespread in the Piedmont region (NW Italy). Vineyards with high Cu contents in the top soil, have been studied. The past Cu input was compared with the amounts of Cu actually measured. Downward migration rate of Cu was investigated by applying a mathematical model. A chemical, physical and mineralogical characterisation of the soil led to an interpretation of the remarkable difference in migration rate. Finally, the migration model was applied to forecast the future Cu evolution within the profiles.
