“…Finally, contaminated biomass should receive adequate treatment and disposal and the limitation caused by the depth of the rhizosphere (Cabral et al 2010;Ferreira and Lamas 2010;Jesus et al 2009;Marques et al 2011;Melo et al 2010;Pires et al 2003;Siebeneichler et al 2008). Phytoremediation can be implemented in different scenarios for the treatment of contaminated areas, a step that should be analyzed according to the objectives and variables of the site (Mishra et al, 2020). The analysis of mechanisms may favor the process for choosing phytoremediation, which should evaluate the interaction between plants, contaminants, and soil (Brehm et al 2013;Jaskulak et al 2020).…”

The contamination of soils and groundwater has attracted worldwide attention, since many contaminants are poorly biodegradable and can accumulate in living organisms, causing implications for plants, animals, and human health. The high cost of conventional remediation processes stimulates research for the development of innovative and more sustainable techniques. Likewise, phytoremediation is a cheap technology that uses plants to absorb, transform, and detoxify contaminants through in situ (phytoextraction, phytotransformation, and phytovolatilization) and ex situ mechanisms (phytostabilization and phytostimulation). Recently, phytoremediation has been adopted as a more profitable technique than physicochemical processes. Otherwise, the existence of variables, such as interactions between climate, soil, and plants, requires analysis methods for its implementation, which ensure the reduction of time and cost and improve its efficiency. Research on the application of different phytoremediation techniques is still in progress, and therefore, this study evaluated the main advantages of phytoremediation through a literature overview, comparing the most adequate remediation models in terms of economic, social, and environmental aspects. Highlighted Conclusions1. Phytoremediation consists of the use of plants and their associated microbes for environmental cleanup and recovery of contaminate soil. 2. Phytoremediation promotes social-economics benefits comparing to the conventional techniques, and ensures sustainability in environmental rehabilitation.

“…Currently, a wide variety of applications exist for transgenic plants in organic pollution phytoremediation, such as pesticides, explosives, organic hydrocarbons, phenolics, and organic solvents (Azab et al, 2018). The transgenes present in these plants are responsible for enhancing plant tolerance to pollutants or increasing metabolic activity under pollution stress (Mishra et al, 2020).…”

“…The genetic manipulation of enzymes involved in phase I and phase II of xenobiotic metabolism is considered an important approach to enhancing the phytoremediation of organic pollutants. Dioxygenases or cytochrome P450, as well as glutathione-S-transferase, are implicated in the enhancement of organic contaminant phytoremediation (Maestri & Marmiroli, 2011;Mishra et al, 2020). Other approaches target specific types of pollutants, such as the manipulation of laccases and peroxidases, to remediate phenolic compounds and nitroreductase or pentaerythritol tetranitrate reductase for the removal of TNT (James & Strand, 2009; Aken, Phytoremediation of Crude Petroleum oil Pollution: a review Egypt.…”

Egyptian Journal of Botany http://ejbo.journals.ekb.eg/ Review 43 E NVIRONMENTAL pollution is exacerbated by the rise in petroleum hydrocarbons due to exploration, production, transportation, and industrialization. This requires immediate remediation. Although crude oil removal using conventional techniques is efficient for cleaning up aquatic and terrestrial ecosystems, it is costly and requires specialized staff and equipment. Despite their negative environmental consequences, chemical compounds such as dispersants, cleansers, emulsifiers, biosurfactants, and soil oxidizers are highly utilized. Phytoremediation and bioremediation have emerged as cost-effective and environmentally friendly technologies. This paper aims to review the impacts of crude oil pollution and the phytoremediation of polluted ecosystems. We have reviewed various phytoremediation/bioremediation mechanisms and environmental factors. Additionally, we have discussed the degradation of crude petroleum, factors affecting petroleum hydrocarbon bioremediation, and the environmental consequences, such as DNA and epigenetic mutations. We have also compared the economics of phytoremediation and restoration of polluted sites with conventional technology. Plants can remediate the environment through phytodegradation, phytostabilization, phytovolatilization, evapotranspiration, and phytoaccumulation. The microbial activities in the plant rhizosphere enhance the degradation and accumulation of the pollutants and modulate their bioavailability, thereby remediating the polluted areas and stabilizing the soil fertility.

“…Five special types of phytoremediation have been defined for removing POPs from the environment: 1) Phytodegradation, degrading organic pollutants in the soil or within the plant tissue through specific enzymes that the plant roots secrete; 2) Phytovolatilization, taking up pollutants from the soil or water and releasing them into the atmosphere through plant transpiration; 3) Phytostabilization, focusing mainly on soil pollutants near the roots, resulting in a reduction of soil erosion; 4) Phytoextraction, using the ability of plants or algae to remove contaminants from soil or water and concentrating them above ground in the plant biomass; 5) Phytostimulation, removing dangerous organic contaminants from soil using organisms within the rhizosphere (Nwoko 2010;Mishra et al, 2020) (Figure 1).…”

Soil contamination caused by industrial and agricultural activities is an environmental problem that poses a serious risk to human health and the ecosystem. Persistent organic pollutants (POPs) are organic chemicals that persist in the environment for long periods because of their high resistance to photolytic, chemical, and biological degradation. Besides POPs, high concentrations of non-essential heavy metals and metalloids, such as arsenic, cadmium, and lead, are increasingly becoming a problem worldwide. Remediation strategies for organic and inorganic pollutants in the environment have received global attention. For organic or inorganic contaminants, phytoremediation is the strategy of choice because of a green technology that uses plants and solar energy to clean hyper-accumulated toxic pollutants from the environment. Some plant species have a high capacity to grow and survive in elevated levels of contaminants. With a long cultivation history and adaptability to a wide range of territories, alfalfa has not only widely been used for animal feed and a medicinal herb but is also an ideal natural resource and model plant for remediation of contaminated soils, offering a variety of elite characteristics. This review provides, firstly, abundant genomic information on the genetic diversity and population structure of alfalfa. Secondly, we focused on the transgenic alfalfa plants for enhanced phytoremediation of POPs, such as atrazine, polychlorinated biphenyl (PCB), and trichloroethylene (TCE), as well as phytoremediation of petroleum and heavy metals. Thirdly, the future perspective of enhancement of phytoremediation efficiency was discussed in depth. This review is intended to provide a comprehensive overview of the phytoremediation capabilities of transgenic alfalfa plants, presenting fundamental information for future research studies for enhancing phytoremediation efficiency.
