- HEAVY METALS BIOABSORPTION AND SOIL STABILIZATION BY Sarcocornia neei FROM EXPERIMENTAL SOILS CONTAINING MINE TAILINGS Bernardo Sepúlveda Mario Tapia Patricia Tapia Francisca Milla Osvaldo Pavez Ciencias de la Tierra Mn Atacama Copiapó metalophytes bioabsorption In the Atacama region of northern Chile, there are a large number of abandoned mines and dams with tailings and little flora development. Sarcocornia neei, a halophytic plant growing in Chilean coastal areas, is highly tolerant to contaminated soils associ-ated with mine tailings. The potential for bioabsorption of heavy metals and arsenic and the substrate stabilization by this species was evaluated in soil experimentally contaminated with mine tailings from the Copiapó Valley. Sarcocornia neei grew well, although more slowly, in experimental soils containing mainly Fe, Cu and Mn. In an advanced vegetative development stage, S. neei roots were able to stabilize the contaminated experimental soils, agglomerating them in more than 80 % and extract-ing chemical elements from them. These characteristics are potentially useful for phytoremediation and reduction of contamination by fine-size particles from mine tailings and contaminated soils. 2020 artículo científico 0188-4999 https://www.redalyc.org/articulo.oa?id=37072379006 https://www.redalyc.org/journal/370/37072379006/ https://www.redalyc.org/journal/370/37072379006/html/ https://www.redalyc.org/journal/370/37072379006/37072379006.epub https://www.redalyc.org/journal/370/37072379006/movil 10.20937/RICA.53027 en http://www.redalyc.org/revista.oa?id=370 Revista Internacional de Contaminación Ambiental application/pdf Universidad Nacional Autónoma de México Revista Internacional de Contaminación Ambiental (México) Num.3 Vol.36
