“…Phytoremediation is a relatively straightforward technique as it does not require any highly specific personnel and exclusive equipment. This is applicable for the remediation of large scale area where other conventional techniques prove to be extremely inefficient and costly as well [48].…”

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.

“…It has been suggested that some of these channels may be non-specific. [41] However, Cu, Cr, and Zn are essential micronutrients for vegetation growth, and Pb is known as a cumulative metabolic poison, [11] meaning competitive adsorption occurs among trace metals. During wetland restoration, mixed vegetation types have an effect on the reducible fractions of Cr and Zn and the oxidizable fractions of Cr, Zn, and Pb (Figure 3 and 4).…”

To understand the effects of planting patterns on trace metal fractions in degraded wetland soils in the Jinjiang Estuary, the chemical speciation of trace metals (Cu, Cr, Zn, and Pb) before and after wetland restoration is analyzed based on a measurement and testing program. The results show that wetland restoration, in general, increases the ratios of Cu, Cr, Zn, and Pb in the acid‐soluble fraction and the ratios of Cr, Zn, and Pb in the residual fraction and decreases the ratios of Cr, Zn, and Pb in the reducible fraction and the ratios of Cu, Cr, Zn, and Pb in the oxidizable fraction; thus, the mobility of Cu increases, and the mobility of Cr, Zn, and Pb decreases. Moreover, the planting patterns influence the levels of Cu, Cr, Zn, and Pb to some extent. After wetland restoration, the levels of Cu show an upward trend, and the Pb levels exhibit a downward trend. However, the potential ecological risk of Cu, Cr, Zn, and Pb fail to decrease. The restoration time may have been too short. The results of this study indicate that the planting patterns influence the transformation of trace metal fractions in soil and affect the pollution degree and potential ecological risk, contributing to a better understanding of the effects of planting patterns on trace metals following wetland restoration. The results will be helpful for subsequent scientific research on wetland restoration.

“…Compared with these techniques, phytoremediation could be defined as using plants to remove toxic contaminants from soil and water to mitigate contaminated sites (Leguizamo et al, 2017). Phytoremediation is considered as low-cost and environmentally friendly green technology to remediate the contaminated regions (Zhang et al, 2009;Wang et al, 2012;Chen et al, 2014;Leguizamo et al, 2017). It is based on the use of natural plants capable of extracting hazardous substances (Ebrahimi, 2016;Mahar et al, 2016).…”

This study was conducted to determine phytoextraction efficiency of Puccinellia distans (Jacq.) Parl. for Pb (450 mg kg -1 Pb(NO3)2) and the application of EDTA and DTPA (2.5DTPA, 5DTPA, 2.5EDTA, 5EDTA, 2.5EDTA+2.5DTPA, 2.5EDTA+5DTPA, 5EDTA+2.5DTPA, 5EDTA+5DTPA) on the Pb uptake and the potential for leaching of Pb during the phytoextraction process. Bioconcentration factor (BCF), translocation factor (TF) and tolerance index (TI) were calculated to determine Pb phytoextraction efficiency. Results showed that DTPA appeared to be more toxic to the plant than EDTA. Plants with combined treatments of EDTA and DTPA exhibited higher decrease in biomass compared to those that had received a treatment of EDTA and DTPA alone. 5DTPA and 5EDTA were the most efficient ratio for increasing concentrations of Pb in the shoots. DTPA showed much higher efficiency than EDTA. BCF of the shoot was relatively higher than the BCF of root. Thus, the plant would be applicable for Pb phytoextraction. Addition of chelates had virtually significant effect on Pb uptake by the plant and elevated Pb concentration in the soil and plant parts. Optimum phytoextraction was observed when 5mg kg −1 EDTA and DTPA was added alone in single dosage to reduce the Pb-chelates leaching risk.
