“…The Fe(III) ions were precipitated as Fe(III) hydroxide when BC was amended. The iron-bearing mineral was formed and bonded arsenate and arsenite, which may play a significant role in As immobilization of Fe(II) in our study [24,25].…”

“…More rice plant tillers mean a higher yield of rice [32]. As is well known, Fe as an essential mineral elements for the chloroplast synthesis and enzymes involved in the biosynthesis express has a very important role in graminaceous plants [33], and thus promotes plant growth [24,34]. The iron may generate the formation of iron plaque on the surface of root, promoting the growth and bifurcation of root [23].…”

“…Combining Fe-base materials and biochar to amend Cd and As co-contaminated soil have been reported, such as Fe(II) combination with compost, as a promising approach to deal with metals co-existing in high concentrations in soil [24,25]. However, in the paddy soils system, soil functions and services should be improved while considering the mitigation of metal toxicity.…”

Excessive accumulation of cadmium (Cd) and arsenic (As) in rice (Oryza sativa L.) poses a potential health risk to populations. Cd and As exhibit opposite geochemical behavior in paddy soil, using appropriate remediation materials to reduce their migration and inhibit their uptake by rice is a great challenge. A pot culture experiment was conducted to investigate the effects of application of silkworm excrement biochar (BC) and ferrous sulfate (Fe(II)) on available Cd and As in paddy soils and their uptake by rice. Results showed that the application of BC + Fe significantly accelerated the tillering of rice plants, and the addition of BC alone to soil did not have a significant effect on the pH of soil, while applied 1% (w/w) BC and 1% (w/w) Fe(II) (1BC-1 Fe(II)) treatment could markedly reduce the soil pH. BC+Fe(II) could reduce the content of available Cd (reduced by 10%–23%) and As (reduced by 6%–33%) in soil. BC+Fe(II) has a distinct decreasing effect on the available As, thus inhibiting As uptake in rice tissues, and the effect was more obvious with an increasing mass ratio of Fe in BC+Fe(II) treatment. BC+Fe(II) decreased bioaccumulation factors (BF) of As compared to control and BC alone treatments. Compared with As, Cd was more readily transferred from the root to the shoot and accumulated in rice eventually. These findings provide a safe and reliable remediation strategy though application of BC+Fe(II) in Cd and As co-contaminated soil. However, the improvement effect of amendments should be paid a special attention on soil pH.

“…Therefore, the complexity of multi-contaminated soils can require it is necessary to applythe application of a combination of amendments. Several previous studies showed that amendment combinations had better effects than the single application of the same amendments (Beesley et al 2010, Fresno et al 2016, Oustriere et al 2016). Plant selection is an important criterion for phytoremediation success, and the use of endemic species has shown better results in the past.…”

Metal(loid)soil pollution is a major environmental and health issue, requiring these areas to be remediated, for example through phytoremediation processes. In order to allow proper plant establishment and growth, amendments must be applied to highly contaminated and poorly fertile soils. Amendments are diverse, but many studies have shown the beneficial effects of biochar, manure and ochre, although studies on their combined use are scarce. Moreover, no studies have evaluated the effect of these combined amendments on endemic plant growth. Endemic plants growing on contaminated soils showed higher tolerance towards pollutants compared to plants coming from unpolluted areas. Therefore, the aim of the present study was to evaluate both the effect of amendments (single or combined) on the physico-chemical properties of a former mining technosol, and the growth and metal(loid) accumulation ability of endemic Agrostis capillaris plants. This study revealed an improvement in the soil physico-chemical properties following the application of amendments, with combined amendments showing better results than the application of just one. On top of this, Agrostis plants performed better on the amended technosols, especially the ones receiving manure, due to its high nutrient content. Finally, based on soil properties, plant growth and the metal(loid) accumulation profile, the use of biochar combined with manure seems to be the most appropriate treatment. Indeed, this treatment showed an improvement in both soil fertility and plant growth. Moreover, Agrostis plants grown in these conditions were among those showing higher root metal(loid) concentration associated to a lower translocation toward aerial parts.

“…A wide range of iron-based materials have been used for metal immobilization in contaminated soils including iron oxides, zerovalent iron, nano-zerovalent iron (nZVI), supported NVI, iron sulfide, green synthesized iron oxide nanoparticle (GION) or phytogenic iron oxides, Fe-Al layered double hydroxide and CMC (carboxymethylcellulose) based iron (Zhang et al, 2014;Frick et al, 2019;Mitzia et al, 2020;Fresno et al, 2016;Su et al, 2019;He et al, 2018). Iron oxides are generally used in contaminated sites because they are regarded as scavengers of trace metals in soils due to their high reactivity and large surface area (Zhang et al, 2014;Nejad et al, 2018).…”

Remediation of contaminated soils is an important task which aims to reduce the impact of toxic metalloids such as Cd, Cu and As on public health. In-situ immobilization via the addition of soil amendments such as iron-based materials reduces the mobility and transport of these toxic metalloids in the environment. A wide range of iron-based materials have been used for metal immobilization in contaminated soils including iron oxides, zerovalent iron, nano-zerovalent iron (nZVI), iron salts, green synthesized iron oxide nanoparticle (GION) or phytogenic iron oxides nanoparticles (PION), Fe-Al layered double hydroxide and CMC (carboxymethylcellulose) based iron. The reactivity and surface area of zerovalent iron is increased at the nanoscale when utilized as nZVI thereby increasing its effectiveness as demonstrated by previous studies. The efficiency of nZVI in remediation of contaminated soils is limited by the strong tendency of its particles to agglomerate. In order to overcome this limitation and facilitate the delivery and mobility of nZVI in soils, nZVI is immobilized onto a carrier such as resin, potato starch, zeolite, or mesoporous silica or by increasing colloidal stability with the addition of other soil amendments. Even though, there is g rowing concern over the environmental impact of nanoparticles, the use of plant extracts to synthesize iron nanoparticles is environmentally friendly and economical.
