Considering that mining environmental liabilities are those installations, effluents, emissions, remains or deposits of waste produced by old abandoned mining operations that constitute a permanent and potential risk to the health of the population, the surrounding ecosystem and property. Therefore, they constitute one of the main sources of contamination by toxic elements, among them, the mobilization of metallic load in the acid drainages produced by the oxidation of sulfides. These discharges with contributions of heavy metals represent a potential risk of accumulation in the tissues of the surrounding plant species in areas of location of mining environmental liabilities.
The present work focuses on evaluating the bioaccumulation of heavy metals in the tissues of aquatic vegetation (macrophytes), mainly in species such as: Anomobryum prostratum, Marchantia Polymorpha L. and Bryophyta sp., and terrestrial vegetation in species such as: Stipa mucronata, Festuca dolichophylla and Cortaderia sp., in areas surrounding old abandoned mining facilities.
The actions of remediation of Mining Environmental Liabilities in Peru, allows to undertake studies to evaluate the effect of the bioaccumulation of metals in macrophyte species induced by the different concentrations of heavy metals present in the water column, in the case of terrestrial vegetation is evaluated the bioaccumulative effect of these due to the effect of the metals present in the soil.
