GAGO, I. et al. Lavandula stoechas L. as phytoremediation species. Rev. de Ciências Agrárias [online]. 2022, vol.45, n.4, pp.1141-1150.  Epub 01-Dez-2022. ISSN 0871-018X.  https://doi.org/10.19084/rca.28762.

One of the current environmental problems is the increase in the concentration of pollutants in the environment. Mining activities can generate pollutants that accumulate in the soil. This problem leads to a deterioration of the ecosystems in which a large accumulation of metalloids appears, seriously affecting both living beings and the biotope. Some plant species have managed to develop tolerance to these pollutants, absorbing or stabilizing them, being able to improve the quality of the ecosystem. Some plant species can be used as an effective and safe method to recover vulnerable areas or those susceptible to the accumulation of potentially toxic elements. The present study deals with the possible use of Lavandula stoechas L. as a phytoextracting plant to reduce the contamination of potentially toxic elements. The phytoextraction capacity for two elements (Pb and Zn) has been evaluated in an abandoned mining area in the SW of the Iberian Peninsula, called La Sierra mine, where it has been seen that lavandula can develop in soils where the concentration of Zn and Pb is 506.05 and 461.41 mg/kg respectively. The use of this species is proposed for the minimization of metal(oid)s.
