CRUZ, Eber Eloy Contreras-De la et al. Concentration of heavy metals lead and arsenic at the Mollebamba dump, Huancavelica. Rev. Inv. Cs. Agro. y Vet. [online]. 2023, vol.7, n.19, pp.64-71.  Epub Jan 09, 2023. ISSN 2664-0902.  https://doi.org/10.33996/revistaalfa.v7i19.198.

Soil contamination in solid waste dumps is a growing problem due to anthropogenic activity, including heavy metals whose accumulation in soil, water and plant tissues constitutes a risk to public health. The purpose of the study was to determine the contamination by heavy metals lead and arsenic in the Mollebamba solid waste dump of the Municipality of Acobamba, Huancavelica. The research was descriptive and observational, and the data were processed using the SPSS statistical package, SPSS Vers. 24, with a confidence level of 95%; sampling was carried out using the manual sampling system, with a depth of 40 cm, measuring the parameters of temperature and relative humidity with Boeco Germany model multiparameter equipment (with probe). For the analysis of heavy metals, it was sent to Envirotest Environmental Testing Laboratory S.A.C., accredited by the National Institute of Quality (INACAL). From the total of 6 sampling points evaluated, the values of lead (Pb) concentration were obtained were 2.50- 3.80- 4.50- 4.00- 4.30 and 4.90 mg/kg, finding the values lower than the Maximum Permissible Limit (MPL) according to Environmental Quality Standards - (ECA) for soil N° 011-2017-MINAM which is 70 mg/kg. It is concluded that, Lead in the six sampling points resulted values lower than the MPL, as for arsenic were obtained in the sampling points P5 and P6, values 20.80% and 37.50% respectively higher than the MPL, being the other points P1, P2, P3 and P4 lower than MPL.
