The use of phytoremediation to solve problems of soil contamination has appeared as a lower cost alternative to conventional treatments. For a plant to be used in the phytoremediation process it needs to have the capacity to extract and accumulate metals. Also, there are substances that can be added to plants to improve extraction efficiency. Based on this, the phytoremediation capacity of the marigold (Tagetes erecta) assisted with EDTA and mycorrhizae was analyzed. Specifically, the capacity of the marigold to extract lead from contaminated soils in the “Bosque de Aves” area of the “Parque Zoológico de Huachipa” (PZH) was evaluated. For this, the marigold planting was carried out in the areas of greatest interest within the PZH, with treatments of different concentrations of mycorrhizae (0 and 0.5 g / kg) and EDTA (0, 0.5 and 1 mg / kg), to later be analyzed by atomic absorption spectrophotometry and analyze the concentration of lead in the aerial and radicular parts of the plants at the end of the experiment. This research showed that the marigold is a plant with lead extraction capacity, and that although under the conditions of the experiment, mycorrhizae did not show an improvement in extraction efficiency, EDTA did increase the amount of lead extracted, so that the physiological development of the plant was affected.
