“…All samples have a high concentration of Ni (620-826 mg kg −1 ) and Cr (695-1035 mg kg −1 ), and there is no the obvious difference between polluted and other soils content (supplementary Table 1). However, the total concentration of Ni and Cr could not be indicator of sewage-irrigation pollution in SR soils because not only the existence of high total concentration of Cr and Ni is an evident geochemical characteristic of serpentinitic and ultramafic-derived soils [4] but also SR soils normally have high concentration of these elements [30].…”

The present study identifies the effects of sewage irrigation on the surface soils geochemistry and the concentration of heavy metals in plants of Sabzevar area, which were irrigated for a long time by wastewater. This study shows that the sewage irrigation has led to decreasing pH and increasing organic matter, and also it makes the accumulation of P 2 O 5 , high-field-strength elements (Ga, Ta, Th, U and Y) and heavy metals (Cd, Co, Cu, Pb, Sn and Zn) in contaminated soils. Likewise, the concentration of rare-earth elements (REE) in contaminated soils is more than background samples with moderate enrichment of light REE compared with high REE in REE pattern diagram (mean La N /Lu N = 5.77). The calculated transfer factor and enrichment factor indexes in plants grown on the polluted soils are significantly higher than the control samples which show the heavy metal enrichment in the contaminated samples. Although the cultivated crops on this area (maize, beet, alfalfa, barely) are used only for animal feed, the heavy metal analysis indicated that the concentration of Cr, Cu, Ni and Pb in these plants, especially alfalfa and maize, is more than the maximum permitted levels defined in different standards.

An experimental investigation is conducted to explore the suitability of Lolium perenne L., diatomite, chalcedonite, dolomite, and limestone for the phytostabilization of Ni and Cu in contaminated soil. A controlled greenhouse study is conducted. The soil is enriched with rising dose of Cu and Ni, that is, (0, 150, 250, and 350 mg kg À1) and (0, 150, 300, and 450 mg kg À1 ), respectively. The phytostabilization potential of perennial ryegrass is evaluated using a bioaccumulation coefficient and translocation factor. Pseudo-total and available metal content (0.01 M CaCl 2 ) in soils and bioaccumulated content in plants are defined in laboratory experiments using spectrophotometry experimental technique. L. perenne is adequate in phytostabilization aided programs, simultaneously, diatomite, chalcedonite, dolomite, and limestone used as modifiers are effective in reducing the accessibility and mobility of metals in Cu-and Ni-polluted soils. The finding of the present study suggests that the studied element in the roots and above-ground parts of L. perenne differs significantly upon applying mineralbased modifications to the soil, synchronously the effect of increasing Cu and Ni levels. Application of dolomite and limestone to the soil cause the highest percentage of the above-ground biomass. Diatomite along with limestone cause a significant boost of Cu and Ni absorption in the roots. Limestone causes an increase in the contents of K, Na, and Ca, as well as a reduction in P in the above-ground parts of L. perenne. Limestone and chalcedonite leads to the highest decrease in available Cu and Ni.

“…Some soils fall below, and some above, these thresholds. The main factor controlling soil concentrations is the composition of the parent material (Tra and Egashira, 2001;Doelsch et al, 2006a,b;de Oliveira et al, 2011;Mendoza-Grimón et al, 2014;Cabral Pinto et al, 2015;Cox et al, 2017;Mazhari et al, 2017;Vlček et al, 2017;Fabrício Neta et al, 2018;Memoli et al, 2018;Iskandar et al, 2019;Bocardi et al, 2020;Wang et al, 2020). This is expected given the tendency of Ni and Cr to be retained in soils (Alloway, 2012).…”

Phytoprevention of Heavy Metal Contamination From Terrestrial Enhanced Weathering: Can Plants Save the Day?

Enhanced weathering is a promising approach to remove carbon dioxide from the atmosphere. However, it may also pose environmental risks through the release of heavy metals, in particular nickel and chromium. In this perspective article I explore the potential role of plants in modulating these heavy metal fluxes. Agricultural basaltic soils may be valuable study sites in this context. However, the effect of biomass harvesting on the accumulation of heavy metals is currently not well studied. Mostly caused by different parent rock concentrations, there is a large variability of heavy metal concentrations in basaltic and ultramafic soils. Hence, to minimize environmental risks of enhanced weathering, basalts with low heavy metal concentrations should be favored. Existing phytoremediation strategies may be used to “phytoprevent” the accumulation of nickel and chromium released from enhanced weathering in soils. As a result, elevated nickel and chromium concentrations in rocks must not preclude enhanced weathering in all settings. In particular, hyperaccumulating plants could be used as part of a crop rotation to periodically remove heavy metals from soils. Enhanced weathering could also be employed on fields or forests of (non-hyper) accumulating plants that have a high primary production of biomass. Both approaches may have additional synergies with phytomining or bioenergy carbon capture and storage, increasing the total amount of carbon dioxide drawdown and at the same time preventing heavy metal accumulation in soils.
