“…Major contaminants of concern include heavy metals, radionuclides, pesticides, explosives residues, and other organic compounds (Kumar et al, 2017;Marmiroli et al, 2007;Salt et al, 1998). Traditional methods for soil restoration include physical excavation of contaminated soil, chemical stabilization of contaminants, and simple non-biological processes, such as incineration, to sequester or volatilize contaminants from soil.…”

“…Phytoremediation is the process of using plants and/or soil microbes to reduce the effects of environmental contaminants (Evangelou et al, 2015; Greipsson, 2011), and it has been of particular interest as a cost‐effective and environmentally safe method for rehabilitation of contaminated soils. Major contaminants of concern include heavy metals, radionuclides, pesticides, explosives residues, and other organic compounds (Kumar et al, 2017; Marmiroli et al, 2007; Salt et al, 1998). Traditional methods for soil restoration include physical excavation of contaminated soil, chemical stabilization of contaminants, and simple non‐biological processes, such as incineration, to sequester or volatilize contaminants from soil.…”

“…Recently, the possible synergies between phytoremediation and bioenergy production have been increasingly investigated (Kumar et al, 2017). Phytoremediation will remove harmful contaminants and improve soil quality and at the same time renewable bioenergy such as biogas could be produced by utilizing the biomass harvested from the phytoremediation process (Hunce et al, 2019).…”

“…This is due to the fact that the robust growth of P. purpureum during phytoremediation of contaminated soil and wastewater also indicates an increasing supply of fermentable sugars needed for the increased and continued bioenergy production. This integrated approach can lead to a more sustainable, ecofriendly, and economical alternative to conventional energy resources (Kumar et al, 2017). This is also one of the zero-waste concept management since all the biomass is being fully utilized (Figure 4).…”

Organic and/or heavy metal pollutants in soil and wastewater can be remediated by phytoremediation. Phytoremediation combines the disciplines of plant physiology, soil microbiology and soil chemistry. There are several ways by which plants extract, stabilize, filtrate, volatilize or degrade the contaminants. However, the effectiveness of phytoremediation relies upon the type of plant used. Pennisetum purpureum, commonly referred to as Napier grass, is one of the exceptional phytoremediators due to its rapid growth rate and ability to survive in highly contaminated soils. In the present review, the potential use and applicability of P. purpureum to remediate various contaminated areas was highlighted and comprehensively discussed, especially the five phytoremediation mechanisms involved (i.e., phytodegradation, phytoextraction, phytofiltration, phytostabilization, phytovolatilization). The application and management of P. purpureum in soil and wastewater phytoremediation were also critically presented. The coupling of phytoremediation and bioenergy is the zero-waste concept that can be applied since P. purpureum contains high lignocellulosic content that can be utilized as carbon source for biofuel production, such as ethanol and butanol.

“…Cannabis sativa L. (hemp) is a multipurpose crop, which is considered as a potential crop for cleaning the soil from HM due to its high biomass production, its long root system, and its capability to absorb and accumulate HM (Ahmad R. et al, 2016;Kumar et al, 2017). It is a promising species for fiber production on low HM-contaminated substrates Hussain R. et al, 2019;Pietrini et al, 2019).…”

Molecular and Biochemical Insights Into Early Responses of Hemp to Cd and Zn Exposure and the Potential Effect of Si on Stress Response

With the intensification of human activities, plants are more frequently exposed to heavy metals (HM). Zinc (Zn) and cadmium (Cd) are frequently and simultaneously found in contaminated soils, including agronomic soils contaminated by the atmospheric fallout near smelters. The fiber crop Cannabis sativa L. is a suitable alternative to food crops for crop cultivation on these soils. In this study, Cd (20 μM) and Zn (100 μM) were shown to induce comparable growth inhibition in C. sativa. To devise agricultural strategies aimed at improving crop yield, the effect of silicon (Si; 2 mM) on the stress tolerance of plants was considered. Targeted gene expression and proteomic analysis were performed on leaves and roots after 1 week of treatment. Both Cd- and Zn-stimulated genes involved in proline biosynthesis [pyrroline-5-carboxylate reductase (P5CR)] and phenylpropanoid pathway [phenylalanine ammonia-lyase (PAL)] but Cd also specifically increased the expression of PCS1-1 involved in phytochelatin (PC) synthesis. Si exposure influences the expression of numerous genes in a contrasting way in Cd- and Zn-exposed plants. At the leaf level, the accumulation of 122 proteins was affected by Cd, whereas 47 proteins were affected by Zn: only 16 proteins were affected by both Cd and Zn. The number of proteins affected due to Si exposure (27) alone was by far lower, and 12 were not modified by heavy metal treatment while no common protein seemed to be modified by both CdSi and ZnSi treatment. It is concluded that Cd and Zn had a clear different impact on plant metabolism and that Si confers a specific physiological status to stressed plants, with quite distinct impacts on hemp proteome depending on the considered heavy metal.
