AB This short paper analyses the concentrations of two major components (Fe, S) and eighttrace elements (As, Au, Co, Cu, Hg, Ni, Mn, Zn) in soils and tailings from Tierra Amarilla (northernChile) using ICP-Ms analysis. The levels of As, Au, Cu, Fe and S are very high and come frompolymetallic sulphides from nearby mines, together with minor contributions of Co, Ni and Mn.Hg has its origin in the extreme seasonal flows of the Copiapó River, which erodes the dumpsof old precious metal mines. These high concentrations require further analysis of possible metalimmobilisation techniques, bioavailability or analysis in cultivated plants.
