Resumen

Geochemical studies under semiarid climates are not always easy because of in dryclimates it is difficult to obtain pore-water geochemical data. Sequential extractions arewidely used for element speciation studies in soil and sediments, and more recently tounderstand the complex biogeochemical element cycling in mine waste environments. In thisstudy, a sequential extraction has been applied to a mining soil with a specific mineralogy inorder to increase the selectivity and the accuracy of geochemical data interpretation.Preliminary results seems to say that although there is a significant pollution level in this area,immediate hazard for the environment is not so important as it seemed to be at a first sightdue to the metal fractioning.
