“…It has been demonstrated that mycorrhizal colonization and tolerance of AMF to heavy metals have shown high variability, resulting from both AMF species and host plant (Liu et al, 2015). Frequently, mycorrhization in some plants has led to higher contents of metals in the roots and lower contents in the shoots (Ferrol et al, 2016;Wu et al, 2016;Gunathilakae et al, 2018). In the present study, we also observed that plants colonized by C. etunicatum and Mix showed higher Mn contents in the roots than in the shoots.…”

“…Similar response was also observed for root dry matter (RDM), where inoculation with the AMF Mix followed by C. etunicatum led to significant increases of 26% and 16.5%, respectively, compared with non-inoculated plants ( Figure 1B). Enhancement in nutrient absorption from the soil solution and protection of plants against toxicity by heavy metals are benefits caused by the AMF which are related to the greater growth, generally in terms of dry matter, in mycorrhized plants (Carrenho, Alves, & Santos, 2018;Gunathilakae, Yapa, & Hettiarachchi, 2018). Li, Sun, Jiang, Chen, and Zhang (2018), studying the attenuation of toxicity by arsenic in Medicago sativa plants colonized by AMF, reported significant increase in shoot and root dry matter of mycorrhized plants at all levels of arsenic.…”

Mining and processing of manganese (Mn) minerals are activities that may result in the generation of large amounts of wastes and serious environmental impacts. Several strategies have been employed to remediate areas with high Mn concentrations, but many of them imply high investments and high risk of secondary pollution. This study aimed to evaluate the phytostabilization potential of Mimosa caesalpiniaefolia Benth. in Mn mining soil influenced by inoculation with arbuscular mycorrhizal fungi (AMF). The experimental design was completely randomized, with four treatments [not inoculated (control), inoculated with Rhizophagus clarus; inoculated with Claroideoglomus etunicatum and inoculated with Rhizophagus clarus + Claroideoglomus etunicatum (Mix)], and four replicates. Inoculation with Mix and C. etunicatum had higher efficiency in protecting plants against excess Mn, due to the greater retention of this element in the roots and lower translocation to the shoots. Inoculation with R. clarus did not influence plant development and reduction of Mn contents in the shoots. The association of the AMF Mix and C. etunicatum with the species Mimosa caesalpiniaefolia Benth. enhances Mn phytostabilization in mining soils with high concentration of this element. The use of multivariate analyses proved to be an important tool with respect to the behavior of biometric, chemical and microbiological variables in mining soil with high Mn concentration.

“…These are the plants with floating leaves and submerged roots. Some of the free-floating aquatic plants are well recognized for their capability to eliminate the metals from the contaminated environment: water hyacinth (Eichhornia crassipes) [128], water ferns (Salvinia minima) [129], duckweeds (Lemna minor, Spirodelaintermedia), [130,131], water lettuce (Pistiastratoites), [132], water cress (Nasturtium officinale) [133]. The potential of these free floating aquatic plant for the elimination of heavy metals is comprehensively studied in different studies [99,134,135].…”

Application of Floating Aquatic Plants in Phytoremediation of Heavy Metals Polluted Water: A Review

et al. 2020

Heavy-metal (HM) pollution is considered a leading source of environmental contamination. Heavy-metal pollution in ground water poses a serious threat to human health and the aquatic ecosystem. Conventional treatment technologies to remove the pollutants from wastewater are usually costly, time-consuming, environmentally destructive, and mostly inefficient. Phytoremediation is a cost-effective green emerging technology with long-lasting applicability. The selection of plant species is the most significant aspect for successful phytoremediation. Aquatic plants hold steep efficiency for the removal of organic and inorganic pollutants. Water hyacinth (Eichhornia crassipes), water lettuce (Pistia stratiotes) and Duck weed (Lemna minor) along with some other aquatic plants are prominent metal accumulator plants for the remediation of heavy-metal polluted water. The phytoremediation potential of the aquatic plant can be further enhanced by the application of innovative approaches in phytoremediation. A summarizing review regarding the use of aquatic plants in phytoremediation is gathered in order to present the broad applicability of phytoremediation.

“…The observations made during the treatment time (4 weeks) can be seen in Table 2. Similar research has also been conducted by [13,33]. In such studies, the concentrations of As, Cd, Cr, Cu, Fe, Mn, Ni and Zn were estimated differently and the displacement efficiency was assessed.…”

“…Furthermore, an evaluation of the changes in nutrient elements (i.e. S, Cl, K, Ca, Mn, Fe, Zn) in the roots, stems, and leaves over time has been examined when the Eichhornia crawled under Cr (VI) [12,13]. Plant cultivation has been conducted according to five Cr (VI) concentrations at 0, 10, 25, 50 and 100mg/L, showing that the increase in Cr enrichment correlates with a gradually decreased content of S, Cl, K, Ca, Fe and Zn.…”

Research on the ability of plants to reduce and transport pollutants, especially heavy metals, remain advancing to date in line with current technological developments. The purpose of this study was to investigate the effect of leachate concentration on the number of tillers of Typha latifolia plants. It also investigated the leaf length and number of leaf petals of these plants. The materials used in this study included liquid/leachate media sourced from a landfill in Banda Aceh, the aquatic plants of Typha latifolia (torch), and heavy metals such as chromium (Cr), mercury (Hg), and lead (Pb). The results showed that the increase in Typha latifolia plant roots occurred at leachate concentration of 20%, 40%, and 60% for sources of 4 cm, 2 cm, and 1 cm. Meanwhile, the leaf length was observed in the leachate concentrations of 20%, 40%, and 60%, resulting in enhancers of 6 cm, 1 cm and 1 cm. Besides, increments of leaf number occurred at leachate concentrations of 20% and 40%, yielding as much as 1 and one leaves on the 2nd and 4th week. The overall results of the study showed an increase in low concentrations.
