Abstract
En áreas de laboreo minero antiguo se encuentran emplazados una serie de estructuras e instalaciones mineras en abandono también conocidas como pasivos ambientales mineros, que en la actualidad constituyen fuentes de contaminación, principalmente por la movilización de carga metálica en los drenajes ácidos producidos por la oxidación de sulfuros. Los mismos que impactan sobre el suelo, agua y flora circundantes a las zonas de emplazamiento de estas antiguas instalaciones. El objetivo del presente trabajo se centra en evaluar la bioacumulación de metales pesados en los tejidos de la vegetación terrestre, principalmente en especies como: Trifolium repens "trébol" y Calamagrostis sp. "ichu"; y la relación que existe entre la cantidad de metales pesados en el suelo de las áreas circundantes a las antiguas instalaciones mineras abandonadas. La evaluación del efecto bioacumulador de las especies de vegetación terrestre, permitirá formular propuestas de remediación y rehabilitación con las especies de mayor amplitud de distribución y abundancia en las zonas ocupadas por pasivos ambientales mineros.
In old mining areas, abandoned mining structures and facilities are also known as mining environmental liabilities. These currently constitute sources of pollution, mainly due to the mobilization of metal loading in acid seepage produced by the oxidation of sulfides, and impacting the soil, water and flora surrounding these old facilities. The objective of this work is to evaluate the bioaccumulation of heavy metals in the tissues of terrestrial vegetation, mainly in species such as: Trifolium repens "clover" and Calamagrostis tarmensis "Ichu"; and its relationship with the amount of heavy metals in the soil of the areas surrounding the old abandoned mining facilities. The evaluation of terrestrial vegetation species' bioaccumulative effect will allow the formulation of remediation and rehabilitation proposals with species of greater distribution and abundance in areas occupied by mining environmental liabilities.
