Heavy metal contamination of land and freshwater resources is a serious concern worldwide. It adversely affects the health of animals, plants and humans. Therefore, remediation of toxic heavy metals must be highly considered. Unlike other techniques, phytoremediation is a holistic technology and can be used in large scale for soil remediation as it is costless, novel, environmentally-safe and solar-driven technology. Utilization of non-edible plants in phytoremediation is an ingenious technique as they are used to generate new bioenergy resources along with the remediation of contaminated soils. Some nonfood bioenergy crops such as Salix species, Miscanthus species, Populus species, Eucalyptus species, and Ricinus communis exhibit high capability to accumulate various metals and to grow in contaminated lands. However, there are still sustainable challenges facing coupling phytoremediation with bioenergy production from polluted lands. Therefore, there has long been a need for developing different strategies to resolve such challenges. In this article review, we will discuss the phytoremediation mechanism, the technique of phytoremediation coupling with bioenergy production, sustainable problems facing linking phytoremediation with energy production as well as possible strategies to enhance the efficiency of bioenergy plants for soil decontamination by improving their characteristics such as metal uptake, transport, accumulation, and tolerance.

“…In recent years, phytoremediation for heavy metal contaminated some mining areas, such as the hyperaccumulator plants of Pteris vittata L., tanzania guinea grass and Arabis alpina L.var.parviflora Franch has been studied under conditions of phytotoxicity and the different fraction of heavy metals ((de Souza Cardoso and Monteiro 2021; Wang et al 2022;Guo et al 2017;Zhang et al 2020). These hyperaccumulator plants has shown promise for phytoextraction of metals due to its high amount of heavy metals absorption and antioxidant mechanism which have the function of eliminating ROS, transforming them into non-toxic compounds (Nematian and Kazemeini 2013;Xu et al 2020;Kathal et al 2016). However, the toxic effects of Pb depend on speciation of Pb.…”

Reducing the bioavailability of Pb in soil is the key to alleviate the toxicity of Pb to plant. Maize were exposed to Pb 100 mg/kg of soil with three fertilizer levels of control (T1), nitrogen, phosphorus and potassium of 204 mg/kg (T2) and nitrogen, potassium of 204 mg/kg (T3). The phosphate supplement lead to the reduction by 24.92%, 29.73% and 25.31% respectively in activity of total superoxide dismutase (T-SOD), peroxidase (POD) and concentration of lipid peroxidation (MDA) in maize leaves, and reduced Pb accumulation in above- and below-ground biomass of maize by 39.20% and 37.58%. In T2 treatment group, the water soluble Pb, ionic fraction and carbonate fraction Pb in rhizosphere soil decreased by 37.57%, 36.36% and 43.24%, and organic fraction Pb and residual fraction Pb was the highest with the value of 11.67 and 18.57 mg/kg; the soil aluminum bound (Al-P) and iron bound phosphate (Fe-P) were the highest with 93.53 mg/kg and 230.32 mg/kg, indicating that the phosphate supplement increases the soil ionic P and transforms the chemically mobilized P (such as O-P, Ca-P) into the bioavailable P. Moreover, the soil organic fraction and residual fraction immobilized Pb was positively correlated with the bioavailable Al-P and Fe-P, indicating that the ionic fraction P (Al-P and Fe-P) react with Pb and produce residual P-Pb compounds. Therefore, phosphate supplement to Pb contaminated soil could transfer unstable fraction Pb into stable fraction Pb by P-induced Pb immobilization, reduce the bioavailability of Pb and alleviate the toxicity of heavy metal to plant.
