    Sammanfattning : The U.S. Southwest is a semi-arid region affected by numerous environmental problems. Chicana/o communities have been directly affected by such problems, especially ever since the region was annexed from Mexico by the United States in the mid-nineteenth century. LÄS MER

  3. 2. Geochemistry of Trace Elements in the Bolivian Altiplano : Effects of natural processes and anthropogenic activities

    Författare :Oswaldo Eduardo Ramos Ramos; Prosun Bhattacharya; Jorge Quintanilla; Roger Thunvik; Jochen Bundshuh; Maria Eugenia Garcia Moreno; Luiz R.G. Guilherme; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arsenic; Bolivian Altiplano; Eastern Cordillera; Trace elements; Surface water and shallow groundwater; Soils and crops.; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : The occurrence of As in groundwater in Argentina was known since 1917; however, the occurrence, distribution and mobilization of As and other trace elements (TEs) in groundwater in the Bolivian Altiplano are still quite unknown. An investigation applying a geochemical approach was conducted in the Poopó Basin and Lake Titicaca to understand processes of TEs in different systems such as water, soils, crops and sediments in mining areas.
