Geochemistry of arsenic (As) in spring and stream waters from San Antonio de los Cobres, NW Argentina
Hudson-Edwards, Karen A. and Archer, J. (2008) Geochemistry of arsenic (As) in spring and stream waters from San Antonio de los Cobres, NW Argentina. Mineralogical Magazine 72 (1), pp. 425-427. ISSN 0026-461X.
Spring and stream waters from the San Antonio de los Cobres area in NW Argentina have high concentrations of arsenic (As) (151-9490 μg l−1), of which AsV varies widely (6-∼100% of total As). Arsenic concentrations correlate with Na, K, Cl, HCO3, B and Li, which are high in the spring waters and are typical of geothermal areas world-wide. Springs near San Antonio supply large amounts of As to the Rio San Antonio de los Cobres (up to 1180 μg l−1), but these concentrations decline to 400 μg l−1 within 10 km of the spring inputs, due to dilution and mineral precipitation.
