“…On the contrary, the willow trees and F. arundinacea benefitted from the NTA application. As stated above, similar results have already been reported [ 70 , 71 ] for different plant species, among which were F. arundinacea [ 31 ] and Salix cultivars. In our case, S. purpurea ‘Fish Creek’ was the most responsive to the NTA application, while Zhivotovsky et al [ 72 ] found a chelator-related growth benefit for the S. purpurea cultivar ‘Allegany’ growing in Pb-contaminated soil but not for S. miyabeana ‘SX64’, ‘SX61’, nor ‘SX67’.…”

Phytoremediation shows great promise as a plant-based alternative to conventional clean-up methods that are prohibitively expensive. As part of an integrated strategy, the selection of well-adapted plant species as well as planting and management techniques could determine the success of a long-term program. Herein, we conducted an experiment under semi-controlled conditions to screen different plants species with respect to their ability to phytoremediate Zn-contaminated soil excavated from a contaminated site following a train derailment and spillage. The effect of nitrilotriacetic acid (NTA) application on the plants and soil was also comprehensively evaluated, albeit we did not find its use relevant for field application. In less than 100 days, substantial Zn removal occurred in the soil zone proximal to the roots of all the tested plant species. Three perennial herbaceous species were tested, namely, Festuca arundinacea, Medicago sativa, and a commercial mix purposely designed for revegetation; they all showed strong capacity for phytostabilization at the root level but not for phytoextraction. The Zn content in the aboveground biomass of willows was much higher. Furthermore, the degree of growth, physiological measurements, and the Zn extraction yield indicated Salix purpurea ‘Fish Creek’ could perform better than Salix miyabeana, ‘SX67’, in situ. Therefore, we suggest implementing an S. purpurea—perennial herbaceous co-cropping strategy at this decade-long-abandoned contaminated site or at similar disrupted landscapes.

“…Phytoremediation efficiency is related to biomass production and heavy metal concentrations in plants; the total content of heavy metals accumulated by plants is the more important factor for evaluating phytoremediation efficiency. 4,20,67 In this study, Pb accumulation in acidic soil without chelator application ranged between 0.91 and 1.29 mg per plant, and the highest Pb content was observed in T4 due to the highest concentration in tissues (Table S5†). Moreover, the highest Pb content in leaflets was found in T1 because its biomass production was significantly higher than that of the other treatments (Table S5†).…”

“…Phytoremediation efficiency depends on the plant's biomass production and the concentration of heavy metals in the plant. Accumulation of heavy metals in plants is thus more important than their concentration in plants [51]. Studies postulate that applying EDTA, NTA, or GLDA increases the accumulation of heavy metals in plants [11,38,52].…”

Recent studies have shown that the combined application of ethylenediaminetetraacetic acid (EDTA) and degradable chelating agents can enhance EDTA’s affinity for heavy metals and reduce its toxicity, but the effect of this combination on the phytoremediation remains largely unknown. This study evaluated and compared the effects of EDTA, nitrilotriacetic acid (NTA), and glutamic acid-N,N-diacetic acid (GLDA) alone (E, N, G treatment), and in combination (EN and EG treatment), on the growth of dwarf bamboo (Indocalamus decorus Q. H. Dai), their phytoremediation efficiency, and the soil environment in Pb-contaminated soil. The results showed that treatment E significantly reduced the biomass, while treatments N and EN were more conducive to the distribution of aerial plant biomass. Except for treatment E, the total Pb accumulation in all treatments increased significantly, with the highest increase in treatment EN. For double chelating agents, the acid-soluble Pb concentrations in rhizosphere and non-rhizosphere soils of treatments EN and EG were lower than those of treatment E, and the soil water-soluble Pb content after 20 days of treatment EN was significantly lower than that of treatment EG. Furthermore, chelating agents generally increased soil-enzyme activity in rhizosphere soil, indicating that chelating agents may promote plant heavy-metal uptake by changing the rhizosphere environment. In conclusion, treatment EN had the highest phytoremediation efficiency and significantly lower environmental risk than treatments E and EG, highlighting its massive potential for application in phytoremediation of Pb-contaminated soil when combined with I. decorus.
