COMPARISON OF PHYTOREMEDIATION WITH NATIVE SPECIES IN THE DRAINED WATERS IN THE TANGANA MOUTH IN THE DISTRICT OF HUACHOCOLPA – HUANCAVELICA

Abstract

In the District of Huachocolpa of the Angaraes Province of the Department of Huancavelica, there are polymetallic mining sites such as the Tangana Mine, despite the high contamination of cadmium and lead by the drained waters of the mentioned mines. The present investigation had the objective of determining the concentration of lead and cadmium by bioaccumulation in roots, stems and leaves of the native species Putacca (Family Apiaceae) and Totora (Scirpus californicus). The biological samples, plants, and water, were taken from the Tangana bocamina and kept in containers and kept in a constant water recirculation system during the time the study was carried out, in addition pumps were placed to oxygenate the plants. Digestion processes, preparation of standards and calibration curves were performed, finally Flame Atomic Absorption spectrophotometer method was used. Putacca and Totora bioaccumulate metals in their roots and leaves. The water of the container with Putacca, in the Initial Time had a concentration of Cadmium of 0.2661 mgCd / L and in the final time 0.0020 mgCd / L and the water of the container with totora in initial time was 0.2661 mgCd / L and in final time 0.0007 mgCd / L, obtaining as a result of this analysis that the Putacca has better absorbency than the Totora, in the case of the lead the Putacca, in the initial time it had a Lead concentration of 25.7220 mgPb / L and in the final time 0.0948 mgPb / L, and in the totora in the initial time 25.7220 mgPb / L and in the final time 0.0037 mgPb / L concluding that in both metals the Putacca has greater absorbance in its roots and stems than the Totora.
