Abstract Considering that mining facilities are effluents, 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 metal cargo in the acid drains produced by the oxidation of sulphides. These discharges with heavy metal contributions represent a potential risk of accumulation in the tissues of the surrounding plant species in areas where mining environmental liabilities are located. 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 Bryofita sp, and terrestrial vegetation in species such as: Stipa mucronata, Festuca dolichophylla and Cortaderia sp., in areas surrounding old abandoned mining facilities. The remediation actions of Mining Environmental Liabilities in Peru, allows studies to evaluate the effect of 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 their bioaccumulative effect due to the effect of metals present in the soil.
