Factor bioconcentración en Ailanthus altissima (Mill.) Swingle. Análisis preliminar

Abstract

Ailanto (Ailanthus altissima (Mill.) Swingle) is one of the most widespread invasive alien species on a global scale. Its main distribution is related to anthropized environments, where soil concentrations of elements (heavy metals or trace elements) can be toxic to other plant organisms. Ailanto has the ability to bioaccumulate these pollutants in its plant tissues (leaves). Thus, this species has been used to analyze the Bioconcentration factor in different anthropized environments (dumps, roads and green areas) as well as naturalized spaces in the Madrid region. The strategies of Ailanthus altissima were also analyzed for the different compounds analyzed in soil. The results indicated that Ailanthus altissima absorbs a large quantity of toxic elements of anthropic origin from the soil. In this sense, the species could be used as a phytoremediator of spaces with contaminated soils, as is the case in regions of China.
