Phytoremediation is defined as the efficient use of plants to remove, detoxify or immobilize environmental contaminants, recovering contaminated soil and water. The mechanism involves the absorption of pollutants by the roots, and accumulation in tissues and the body, leading to the decomposition and transformation of pollutants into less harmful forms (Ansari et al., 2020). Furthermore, phytoremediation is an advantageous ecological technique for the decontamination of environments, as it does not require physical-chemical or engineering processes such as excavation or incineration of the soil, in addition to having a lower cost about these techniques, with its possible execution in situ (Patra et al., 2020; Yang et al., 2005). Also, this technique allows different mechanisms for the detoxification of water, soil, and air contaminated mainly with metals and organic compounds. All of these mechanisms occur after the xenobiotic absorption by the plant and are described in Table 1, for each phytoremediation technique (Yang et al., 2005). The literature shows us that although they have reported that phytoremediation, in general, has attractive advantages when compared to other more complex processes for the remediation of contaminated waters and soils, this technique has mainly longer execution times. However, when we analyze each technique specifically (as described in Table 1), they all have specific care, added to unmatched pros and cons. This information is described in Table 2.
