“…Phytoremediation is used to treat areas contaminated with heavy metals to reduce the distribution and phytotoxicity of contaminants to the environment and human health. This method is highly efficient, can be used in large, contaminated locations, has low operating costs, is environmentally friendly, and can be used in polluted areas without affecting the environment [ [13] , [14] , [15] , [16] , [17] ]. In addition, plants used for phytoremediation must be thriving, have a high ability to absorb and store heavy metals, have a short life cycle, produce a substantial amount of biomass, have a wide root system, reproduce well, and be easy to maintain [ 18 ].…”

“…Several phytoremediation mechanisms can be used for arsenic decontamination, including phytoextraction and phytostabilization. Several terrestrial plant species have been used to remove arsenic from contaminated soil via phytoextraction, including Bambusa bambos, Pennisetum purpureum, Vetiveria zizanioides (Sampanpanish & Suwattiga, 2017), Zea mays (Mehmood et al, 2021), Salix purpurea 'Fish Creek', Festuca arudinacea, Medicago sativa, and Brassica juncea (Yanitch et al, 2020). The phytostabilization of arsenic has been reported less than phytoextraction, but it is still interesting.…”

The limited translocation of arsenic from contaminated soil to plant biomass is one way to decrease human exposure to arsenic (As). Plant growth regulators (PGR), including salicylic acid, indole butyric acid, and calcium, have been reported to alleviate toxicity and decrease the accumulation of heavy metals in many plants. Thus, this study has investigated the effect of plant growth regulators, including salicylic acid, salicylic acid + calcium chloride, indole butyric acid, and indole butyric acid + calcium chloride, to stimulate the growth and phytostabilization of Pennisetum purpureum cv. Mott grew in arsenic-spiked soil. The results showed shoot growth, root growth, and total chlorophyll content of P. purpureum cv. Mott grown in non-spiked soil were not significantly different from those grown in arsenic-spiked soil. Only the root-to-shoot ratio of plants grown under arsenic-spiked soil (0.28) was higher than that of non-spiked soil (0.19). Exogenous plant growth regulator application of each formula did not stimulate the growth of plants grown under both soil conditions. The most suitable plant growth regulator was indole butyric acid + calcium chloride, as the highest arsenic accumulation in plant roots was detected (47.38 mg/kg). It corresponds with the arsenic bioaccumulation factor, translocation factor, and efficiency, which were 4.52, 0.06, and 9.77% when using exogenously indole butyric acid + calcium chloride. Meanwhile, arsenic’s translocation factor and efficiency were low when using the other formulae of plant growth regulators. Thus, 0.001 mM indole butyric acid + 20 mM calcium chloride may be used for the cultivation of P. purpureum cv. Mott as a forage crop in areas with low levels of arsenic contamination because it could limit the amount of arsenic entering the food chain.

This research firstly aimed to study the potential of electrokinetics (EK) on arsenic (As) mobility in gelatin (agar) medium with different containers (spherical or rectangular), electrodes (graphite or stainless-steel grade 316L), and applied electric field (0, 1, and 2 V cm− 1) by dividing the area into nine parts to ascertain the As movement (horizontally and vertically) after 72 h. Secondly, utilizing the optimal conditions for As mobility from the first part, to ascertain the effect of EK with Mott Dwarf Napier Grass (Pennisetum purpureum cv. Mott) for the co-treatment of mine tailings at an applied electric field of 0, 1, 2, and 4 V cm− 1 to examine the As accumulation in the plants and mine tailings after 15, 30, 45, 60, 75, 90, 105, and 120 d. The results showed that As had the highest mobility in agar in the spherical container using graphite electrodes with an applied electric field of 2 V cm− 1. The areas around the cathodes had lower As levels than that around the anode, with a net movement from cathode to anode areas both horizontally and vertically. For the co-treatment of mine tailings with EK and P. purpureum cv. Mott cultivation, the applied electric field provided better As treatment results than without an electric field, and the plants accumulated As in their roots to a greater extent than in the stem and leaves. The highest As absorption capability in the roots of P. purpureum cv. Mott (7.69 ± 0.16 mg kg− 1) was obtained after 90 d with an applied electric field of 1 V cm− 1.
