Induced mobilization of As contained in metallurgical waste using electrokinetic remediation technology: environmental implications and technical limitations in soil remediation of orphan mining areas

In Asturias, diverse geochemical anomalies of As of anthropic origin are located. Some of them are associated with Hg orphan mines. There are many studies that characterize these sites from an environmental point of view, analyzing in turn the risks associated with As and Hg contamination both in sediments and in soils and waters.This work focuses on the analysis of the electrokinetic decontamination of soils with high contents in As. Based on the data obtained from the laboratory on different materials in previous works, it has been sought to combine these with current laboratory and field work to infer the environmental and technical implementation implications of the As mobility in sediments and soils
