Arsenic-contamination source of groundwater from the Salí basin, Argentina

Quaternary loess deposits, reworked by fluvial and aeolian processes, filled the Salí River basin in Tucumán Province, Argentina, and are the source of high concentrations of As, F, V, B, U and Mo in shallow groundwaters. The average chemical composition of loess is similar to that of a dacite and i...
