Resumen

The use of remediation plants is of interest for the remediation of soils contaminated with mining tailings. In this sense, the objective of the research was to evaluate the remediation capacity of plantain (Plantago major) in soils contaminated with lead and zinc. The research was conducted under greenhouse conditions in the districts and provinces of Huaraz, Ancash. A completely randomized design was used with five treatments (0, 25, 50, 50, 75, and 100% tailings concentration) and three replications. Plant height, root length, leaf area, and aerial, root, and total dry mass decreased significantly with increasing tailings concentration. Regarding the translocation factor (TF) and bioconcentration factor (BCF), the values found were less than unity, being considered as a phytostabilizing species. The increase in lead and zinc concentrations in the substrate affected the aerial and root growth of plantain. The observed TF and BCF were lower than unity, which corresponds to a phytostabilizing species with remediation potential for lead- and zinc-contaminated soils.
