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

摘要：

Quaternary loess deposits, reworked by fluvial and aeolian processes, filled the Salí River basinin 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 ofa dacite and it exhibits many components of volcanic origin (mainly plagioclases, quartz, K-feldspar and glass shards). Sorption and desorption processes onto the surface of Fe- and Al-oxides regulate the distribution of trace elements and their mobility in the basin.
