REYNA-NAJERA, Diana Nalleli et al. Study of the Behavior of Plant Species in a Phytostabilization Process for Remediation of Soil Contaminated by Abandoned Mine Tailings. Epistemus (Sonora) [online]. 2022, vol.16, n.32, 08.  Epub 23-Set-2022. ISSN 2007-8196.  https://doi.org/10.36790/epistemus.v16i32.197.

The objective of the study was to evaluate the phytoremediation potential of eight native plants sown with the support of amendments, on the mine tailings from the La Prieta mine in Parral, Chihuahua, Mexico, to phytostabilize heavy metals and metalloid-As in their roots. The concentration of the elements, in the aerial part, root, and soil, was determined following the criterial established by the NOM-147-SEMARNAT/SSA1-2004 standard. The species S. macrostachya and S. aireoides showed the highest copper concentrations with values between 150 and 400 mg/kg, whereas in the rest of the species ranged between 50 and 380 mg/kg. The species S. aireoides, A. Canescens, S. Daysilirium, and S. Macrostachia presented phytostabilization potential by showing Translocation Factor values <0.5, for As, Cu, Pb, and Zn. The species were adapted to the in situ experiment, showing tolerance to heavy metals, metalloid, and potential for phytostabilization.
