    Abstract : The Bolivian Altiplano (BA) is a high plateau located in the western part of the country at an altitude of 3,600 to 3,900 meters above sea level and is bordered by the Eastern and Western Cordillera. Within the BA there is a large endorheic hydrologic system linking the Titicaca Lake in the north the Desaguadero River, lakes Uru-Uru and Poopó in the central part; and the Lacajahuira River and Coipasa and Uyuni salt pans in the south.

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

    Author : Oswaldo Eduardo Ramos Ramos; Prosun Bhattacharya; Jorge Quintanilla; Roger Thunvik; Jochen Bundshuh; Maria Eugenia Garcia Moreno; Luiz R.G. Guilherme; KTH; []
    Keywords : 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;

    Abstract : 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.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytoprotection; Beta-carotene; TBARS; TEAC; ABTS; antioxidant activity; secondarymetabolites; Highland plains; plants; photoprotection; Organic chemistry; Organisk kemi;

    Abstract : Certain climatologically-adverse conditions in the basin of the Poopo Lake, located on the high plateau of the Bolivian Altiplano, have prevented the existence of a reliable agricultural system and the impact on the population of the area has been severe. These problems have been the main motivation in choosing this region for this particular study. READ MORE
