Contamination en métaux lourds des eaux de surface et des sédiments du Val de Milluni (Andes Boliviennes) par des déchets miniers
Approches géochimique, minéralogique et hydrochimique.

Abstract : Heavy metal contamination has been investigated in the Milluni Valley (Bolivia, High Plateau, 4800 m asl) combining geochemical, mineralogical and hydrochemical approaches. For each metal, the mineral source was determined, as well as the geochemical process leading to the weathering of primary minerals into tertiary minerals. The knowledge of the ongoing geochemical processes and of the hydrochemical budgets allowed to determining the origin, the transport pathways and the control parameters of the metals in this environment. Finally, the cores in lake sediments and in peat-bogs of the valley allowed assessing the historical behaviour of heavy metal contamination, especially during the last century.
