“…However, high accumulation of Mn and As in the plant shoots was obtained in comparison with that in other studies [12,13]. In addition, the concentrations of heavy metals and As in this study were lower than those in other aquatic macrophytes including Eleocharis acicularis [9,14], Eichhornia crassipes [15], and Lemna minor L. [16].…”

In this study, Phragmites australis (common reed) was transplanted into solutions added with different concentrations of Mn, Zn, Cd, Pb, and As for 30 days in the laboratory (10 days of incubation and repeated three times without changing the plant) to assess the removal of these metals and its accumulation in the plant. The results showed that high removal efficiency was achieved by growing P.australis. The highest daily removal rates of heavy metals and As were obtained after 1 day of new solution addition. The highest concentrations of Mn, Zn, Cd, Pb, and As in the plant roots were 3920, 1020, 90.9, 1350, and 183 mg kg-1 dry wt., respectively; those in the stems were 465, 108, 26.4, 227, and 74.0 mg kg -1 dry wt.; and those in the leaves were 716, 150, 18.1, 157, and 88.3 mg kg -1 dry wt. The results of this study indicated that P. australis has the ability to remove simultaneously these metals from water, making it a potential species for phytoremediation of wastewater from Pb-Zn mine.

“…Using the plants subcultured with or without of 1 mM Si, we investigated the accumulation of heavy metals from the solution with approximate concentrations of 4 mg/L Zn, 41 mg/L Pb, 47 mg/L Cd, or 38 mg/L In for 14 days (Figure 7). The concentrations of these heavy metals were selected according to the previous reports using E. acicularis [6] and our other experiments to estimate the ability of heavy metal accumulation. In addition, the duration of 2 weeks to expose plants to these heavy metals was selected to estimate minimum capacity of heavy metal accumulation based on the result of Cs removal from the basal solution ( Figure 5) that changes in the Cs concentration were prominent in first 2 weeks.…”

Eleocharis acicularis, an aquatic macrophyte of the Cyperaceae family, has been shown to accumulate multiple heavy metals and has great potential for use in the phytoremediation of contaminated soil and water. To investigate the mechanism of accumulation of heavy metals in E. acicularis while excluding biotic and abiotic environmental effects and to acquire homogenous and sufficient populations of E. acicularis, we established an aseptic culture system and analyzed the applicability of this species for phytoremediation. Young ramet bases and stolon tips of E. acicularis grown in the field were sterilized, cultured, and established in an aseptic culture system, and the effective growth conditions of isolated ramets were determined. Isolated ramets grew remarkably well in a medium of pH 4.8 to 5.7 with 0.25 mg/L kinetin as a plant hormone. Furthermore, capacity for the accumulation of heavy metals was examined using E. acicularis subcultured with or without Si. Aseptically cultured E. acicularis showed a sufficient capacity for Cs and Zn accumulation and exceeded the criteria for hyperaccumulator plants in accumulating Pb, Cd, and In regardless of the addition or not of Si during its subculture. The aseptic culture of E. acicularis enhances its capacity for the accumulation of heavy metals and its applicability for phytoremediation.

“…The remediation of heavy metals polluted sites through phytoextraction (phytomining) 16 is cheaper and more effective as compared to chemical treatments (Ha et al, 2011;Li et al, 17 2014). Biofortification of food products, production of biofuel as new energy resource, 18 acquiring reclaimed land for agriculture and commercial purpose and biochar for climate 19 change mitigation, provides a new insight into the phytoremediation of HMs.…”
