“…The low cost of phytoremediation has been regarded as a significant advantage as compared to the other remediation techniques, such as excavation and soil washing (Kafle et al, 2022;Prasad, 2021;Shahid et al, 2014). Moreover, phytoremediation may save up to about 60-80% to remediate PTEs-contaminated areas as compared to the other traditional remediation technologies (Ashraf et al, 2019;Gunarathne et al, 2019). However, the combined applications of physical and chemical agents, such as chelates to enhance the phytoremediation efficiency may no longer be regarded as a low-cost remediation technology.…”

“…Hence, available bioremediation technologies such as bacterial remediation, mycoremediation, phycoremediation and phytoremediation seen as possible remediation techniques for remediating pollution with less environmental risk (Cristaldi et al, 2017). However, only phytoremediation, the plant-based bioremediation technology, has successfully gained public acceptance as one of the effective techniques due to its simple procedure, low-cost method and environmentally friendly approach (Gunarathne et al, 2019;Kafle et al, 2022;Ng et al, 2020;Sarwar et al, 2017). Correspondingly, many phytoremediation activities have been taken to remediate and recover assorted metals (As, Pb, Cu, Cr, Cd and Hg) with various types of plants and hyperaccumulators (Constantinescu et al, 2019;Ng et al, 2016;Patra et al, 2019;Radziemska, 2018).…”

“…Despite this remediation technology's numerous advantages and significant outcomes, some advancements in the current procedure are still required to improve the traditional phytoremediation. As a result, new research is still emerging in phytoremediation to maximise the removal efficiency of the metals, overcome current limitations and harness other benefits through this technique (Gavrilescu, 2022;Gunarathne et al, 2019). The capacity for phytoremediation is often limited by low bioavailability of the targeted metal in soil or contaminated sites due to residual insoluble forms of the metal and its strong binding to biotic and non-biotic soil ligands (Sinhal et al, 2010).…”

“…Phytoremediation is considered an economical approach to remediate Sb-contaminated soils (Antoniadis et al, 2021;Prabha et al, 2021). It is a green and environmentally friendly approach compared with other methods to carry out the mobilization as well as immobilization of Sb (Gunarathne et al, 2020). Müller et al (2013) performed a study for 7 weeks where they spiked the soil with various levels of Sb (5, 10, and 16 mg/kg) and studied its impact on the plant species Pteris vittate.…”

Antimony (Sb) is a dangerous heavy metal (HM) that poses a serious threat to the health of plants, animals, and humans. Leaching from mining wastes and weathering of sulfide ores are the major ways of introducing Sb into our soils and aquatic environments. Crops grown on Sb-contaminated soils are a major reason of Sb entry into humans by eating Sb-contaminated foods. Sb toxicity in plants reduces seed germination and root and shoot growth, and causes substantial reduction in plant growth and final productions. Moreover, Sb also induces chlorosis, causes damage to the photosynthetic apparatus, reduces membrane stability and nutrient uptake, and increases oxidative stress by increasing reactive oxygen species, thereby reducing plant growth and development. The threats induced by Sb toxicity and Sb concentration in soils are increasing day by day, which would be a major risk to crop production and human health. Additionally, the lack of appropriate measures regarding the remediation of Sb-contaminated soils will further intensify the current situation. Therefore, future research must be aimed at devising appropriate measures to mitigate the hazardous impacts of Sb toxicity on plants, humans, and the environment and to prevent the entry of Sb into our ecosystem. We have also described the various strategies to remediate Sb-contaminated soils to prevent its entry into the human food chain. Additionally, we also identified the various research gaps that must be addressed in future research programs. We believe that this review will help readers to develop the appropriate measures to minimize the toxic effects of Sb and its entry into our ecosystem. This will ensure the proper food production on Sb-contaminated soils.

Harnessing Lignocellulosic Waste‐Derived Carbon Materials for Green Electrochemical Applications

Phytoremediation and constructed wetlands are widely employed processes for the decontamination of soils and waters. These sustainable, effective, and cost‐efficient technologies rely solely on the use of plants. However, the application of these processes results in the accumulation of lignocellulosic residues, like it occurs with natural wetlands, which present a significant challenge due to the potential entry into the food chain of the adsorbed pollutants or the risk of initiating uncontrolled fires due to the accumulation of dead biomass. Nevertheless, rather than being perceived as a drawback, this can be seen as a potential source of materials. Carbonaceous materials are gaining increasing significance in the field of electrochemistry, normally improving their features through some type of thermal treatment. In this study, different types of thermal treatments applied to lignocellulosic wastes are reviewed pointing out pyrolysis and hydrothermal carbonization (HTC). Additionally, four environmental and energy electrochemical applications where this type of waste has been used as precursors of electrode materials are briefly examined: energy storage (supercapacitors, Li−Na‐ion batteries), hydrogen production (H2), microbial fuel cells (MFCs) and hydrogen peroxide (H2O2) production. Recent research findings, as discussed throughout this review, suggest a promising future for the utilization of lignocellulosic waste in electrochemical applications.
