Fitorremediación de suelos contaminados en mecánicas automotrices, utilizando Lolium perenne y Medicago sativa, en laboratorio

Abstract

One of the most prevalent environmental issues is soil contamination due to the spillage of harmful elements, such as automotive residual oil, causing negative impacts on soil's properties and productive capacity. Phytoremediation is an efficient alternative that uses the capacity of certain plant species to extract different contaminants. This research project aimed to analyze the remediation capability of two plant species (Lolium perenne and Medicago sativa) in soils contaminated with automotive residual oils using experimental methods. The findings revealed that, although both selected species have a good capacity for contaminant extraction, Lolium perenne proved to be more efficient. In the case of Lolium perenne, treatment with 25 seeds degraded 44% of the contaminant, and treatment with 50 seeds degraded 54%, being the most effective. In contrast, for Medicago sativa, treatment with 25 seeds degraded 23% of the contaminant, which is the least efficient, and treatment with 50 seeds degraded 39%.
