“…The present study clearly indicates that the efficiency of phytoremediation remains better in the moderately Pb-contaminated soils (Fig. 5) as compared to that of highly Pb-contaminated soils at 50 mg/ kg (Sun et al 2009). The composite application of S and VC increased the phytoextraction rate of C. indicum L. by twofold to ninefolds as compared to the control treatment.…”

“…Zhuang et al (2005) reported that addition of 6 m mol/kg EDTA caused 2-, 13-and 19-fold increase in Pb phytoextraction rate of Vertiveria zizanioides, Rumex hybrid (K-1) and Viola baoshanensis, showing phytoextraction rate (%) up to 0.02, 0.12 and 0.18, respectively. However, Sun et al (2009) reported 0.05 % Pb remediation efficiency of a hyperaccumulator plant, Sedum alfredii H, under EDTAtreated pots at 5 m mol/kg. In the present study, the phytoextraction rate of C. indicum L. remained at par with those of Zhuang et al (2005) and Sun et al (2009).…”

The higher remediation ratios (C0.1) in 8 treatments (containing either S or VC or both), out of total 19 treatments, proved the potential of plants as well as amendments (S and VC) for enhanced clean-up of soils contaminated with lead in the slightly alkaline soils (pH 7.8).…”

The natural potential of Chrysanthemum indicum L. for the clean-up of lead-contaminated soil was investigated under pot experiment. Maximum applied lead (at 50 mg/kg) caused significant reduction in the plant height (31.71 %), root length (31.15 %) and dry biomass (32.71 and 41.25 % for root and shoot, respectively); however, minimum applied lead (at 10 mg/kg) promoted the growth of plants to some extent, over the respective control pots. Lead concentration in the tissues followed the order as root[shoot[flower. The combinatorial treatment T 16 (50 mg/kg Pb, 0.8 g/kg elemental sulphur and 6 g/kg vermicompost) caused maximum concentration of lead in root, shoot and flower up to the extent of 43.58, 22.45 and 9.62 mg/kg, respectively, leading to the maximum bioaccumulation factor (0.38). However, the combinatorial treatment T 4 (sulphur and vermicompost) showed maximum translocation factor (0.63) and T 12 (20 mg/kg lead, 0.8 g/kg elemental sulphur and 6 g/kg vermicompost) produced maximum remediation ratio (0.153). The combinatorial treatments under lead-contaminated (10-50 mg/ kg) soils showed higher remediation efficiency indicating enhanced clean-up of the aforesaid soils through C. indicum L. Applied lead ([20 mg/kg) altered the chlorophylla, chlorophyll-b and carotenoid contents of the plants. Hence, the authors conclude that a non-edible ornamental plant, C. indicum L., is preferred to be safely grown in moderately lead-contaminated soils along with application of elemental sulphur and vermicompost, which will boost the photosynthetic pigments of the plants, leading to enhanced clean-up of the lead-contaminated soil.

“…Soil was collected from the surface layer (0-20 cm) in Sluice Gate III of SZIA, and then air-dried for about 12 days. The soil samples passed through a 2 mm sieve were used for physical and chemical fraction analysis (Bao 2000), those passed through 50 mm sieve were used to determine the concentrations of heavy metals (Sun et al 2009 Pot experiment. Air-dried and homogenized soil equivalent to 2.5 kg (dry basis) was placed in each plant pot (15 cm in height and 20 cm diameter).…”

The primary objective of this study was to evaluate the effect of ethylene diamine tetraacetic acid (EDTA) and citric acid (CA) on Mirabilis jalapa L. growth and phytoextraction of heavy metals from the multi-metal contaminated soil. The results showed that the application of CA (5 and 8 mmol/kg) and EDTA (5 mmol/kg) increased plant growth, while when the concentration of EDTA was up to 8 mmol/kg, the shoot biomass significantly decreased relative to the control plants (P < 0.05); it suffered 48.1%, 53.1%, 58.9%, and 78.2% reduction, respectively, compared to CK, CA-5, CA-8, and EDTA-5. EDTA was more effective than CA at increasing heavy metal uptake in aerial parts of the plants, the shoot concentrations of Cd, Cu, Pb, and Zn increased by 0.55, 3.08, 3.28, and 1.0-fold in the 8 mmol/kg EDTA-treated soils relative to the treatment of 8 mmol/kg CA. The maximum of Cd, Cu, and Pb phytoextraction and remediation factor (RF) were found with 5 mmol/kg EDTA treatment. For Zn, 8 mmol/kg EDTA was most efficient in increasing Zn accumulation in aboveground of M. jalapa.

“…Despite a significant effort in studying the mechanism of phytoextraction and metals deposition, in improving metals uptake by using chelating agents (Sun et al 2009) or even genetic modification of the known species or searching for native hyperaccumulators, some significant hurdles still hamper successful commercialization of the phytoremediation process. The main intrinsic obstacles are: 1) high variety of the plant species involved in extraction of various metals and high inconsistency in rates of uptake even within one family of the hyperaccumulating plants (Adamidis et al 2014);…”
