The objective of this thesis is to study the concentrations of heavy metals in the soil and flora present in the mining environmental liability “Paredones“ located in the District of San Bernardino, province of San Pablo, department of Cajamarca. This mine contains areas of dismantling and relavera of material that continues generating acid drainages and therefore high concentrations of heavy metals. The study has focused mainly on determining the concentrations of heavy metals in soil, the relationship it has with the metals present in the plants and, in the same way, to evaluate if the concentration of metals exceeds the Environmental Quality Standard for commercial, industrial and extractive. The sampling was based on the collection of 1 kg of soil in five points, four of them in the area of the relavera and the last one in an area without impact to be taken as control. With respect to the flora, 4 species (Phragmite australis, Trixis cacaliodes, Acacicia Macracanta and Bursera graveolens) were collected, which were taken at the soil sampling points, both in the tailings and control. The contaminant with the greatest presence in plants is Magnesium with a concentration of 2997 mg / kg and the species that has the most metals retained is Trixis cacalioides (A) in both Relave and Control. The metal with the greatest presence in the soils is El Hierro, reaching a concentration of 65020 mg / kg in the sample of soil 2 tailing, which is also the one with the highest concentration of metals. On the other hand, heavy metals show a relationship such that plants have a similar amount of pollutants to the concentrations that the soil has. That is, if the amount of metals in the soil is high, in the plant it will also be high or vice versa. With this research it is possible to determine the super accumulators of metals that can be used for the biological treatment of mine drainages, this being an economical alternative for the treatment of wastewater.
