“…En este sentido, Sidhu et al (2017) examinaron el género Coronopus didymus, para afirmar que es una planta hiperacumuladora, y puede emplearse prácticamente para aliviar el Cd de los suelos contaminados [71]. De manera similar, sucede en Europa, al momento de acumular el metal pesado (Se); donde en España, Álvarez (2019) describe que utilizó la especie Brassica Napus para hiperacumular este metal en sus hojas [1]. Por otro parte, en América del Sur, específicamente en Perú; al instante de acumular el metal pesado (Hg), Martinez (2018), describe que las plantas de Baccharis salicifolia presentan una mayor capacidad de acumular este metal en las partes aéreas [30].…”

“…Según, Li et al, (2019), Halophyte Halogeton glomeratus solo puede contener 46.65 mg/kg; 0.58 mg/kg; 0.26 mg/kg; 7.24 mg/kg y 55.79 mg/kg; de los metales como Cu, Hg, As, Ni y Zn, respectivamente [53]. Al mismo tiempo, para Álvarez (2019) Brassica napus solo puede contener 3.61 mg/kg; 27.44 mg/kg; 4.03 mg/kg; 5.62 mg/kg; 6.71 mg/kg; 2.49 mg/kg; 0.97 mg/kg y 5.15 mg/kg; de los metales como Co, Cd, Cr, Cu, Ni, Zn, Pb, As y Se, respectivamente [1].…”

“…Las plantas mineras y metalúrgicas, los efluentes industriales, las actividades urbanas, el uso de fertilizantes, los residuos sólidos; han sido considerados como fuentes fundamentales de contaminación del suelo. Esto supone, no sólo un alto riesgo para este recurso finito primordial, sino también, para el medio ambiente y la salud humana [1]. Si bien es cierto, el suelo presta diversos servicios ecosistémicos [2]; no obstante, es lamentable ver que este bien primordial, se vea afectado por los diferentes tipos de contaminación.…”

Currently the presence of heavy metals in the soil considerably affects the environment and human health. Therefore, this review aimed to describe the importance of phytoremediation of heavy metals in the soil, based on the analysis of research articles. For this, the PRISMA methodology was used as a basis, whose general purpose is the impact of heavy metals in soils. The results of this review show a high proportion of national publications corresponding to China (20%), Peru (12%), Colombia and Spain (8%). Likewise, it was determined that there are different types of final disposal classified as agricultural land (69%), urban (20%), mining (7%) and industrial (4%). Also, it is described that the Lonicera japonica Thunb species is presented as the best Cr accumulating plant, because it would offer great opportunities in the phytoremediation process. In this same context, the plant Helianthus annuus L., would behave as a phytostabilizer of soil contaminated by Cd; In this sense, the species Zea mays L., is efficient for the phytoextraction process of heavy metals such as Pb and Cd. Thus, it was identified that the phytoremediation species that have the highest concentrations and dispersions of heavy metals are Miconia sp. and Erica cinerea L.; and the lowest are Halophyte Halogeton glomeratus and Brassica napus. It was concluded that, despite the minimum sustainable, lasting and more effective actions that minimize the risks of contamination; Phytoremediation of heavy metals in the soil is presented as a fundamental low-cost green technology to consider.

The pollution of the planet has generated a series of problems for the environment and human health, such as the case of soils contaminated by heavy metals from batteries that are improperly disposed of in domestic garbage and sanitary landfills; Button batteries (HgO) pollute the soil, since mercury is very persistent in the environment due to its biomagnification and its great capacity to accumulate in organisms causing diseases in humans at the skin level, respiratory tract, digestive system, etc. . this being a highly toxic metal worldwide. The accumulation of Hg in soils depends on physicochemical factors such as pH, redox potential, organic matter, and clay. The main objective of this research work is to implement mercury phytoextraction in soils contaminated by button cells, using “Bamnusoideae” Bamboo, a UV-Vis spectroscopic study was carried out to determine the desorption of Hg from the contaminated soil, images of the stem were obtained, leaves and roots of bamboo without contamination and contaminated with Hg with a VE-B6 microscope, rating: 85V to 265V 50/60 Hz, Halogen Lamp: 12V 30W, and the pH of the contaminated soil was measured.
