“…However, under prolonged flooded and thus reduced conditions, the reductive dissolution of Sb(III)‐bearing Fe minerals may release the immobilised Sb(III) back to soil solution (Hockmann et al, 2014). On the other hand, Wu et al (2022) reported that continuous flooding generally immobilised Sb more than alternate wetting and drying periods. Contrary to Sb, As(III) exhibits higher mobility than As(V) under reducing conditions (Ascar et al, 2008; Mensah, Marschner, Wang, et al, 2022).…”

“…Substantial Sb concentrations were determined in plant tissues of native species in an abandoned Sb mine in China and moreover, different species (trivalent/pentavalent, inorganic/organic) were detected in roots, leaves and stems (Wei et al, 2015). Higher Sb uptake by rice was observed in continuously flooded soils compared to the alternation of wet and dry periods (Wu et al, 2022). In amended soils, the As uptake by sunflower and ryegrass was decreased by 47%–61% using nZVI and no negative impact of the plant roots presence on the nZVI functionality was observed (Vítková et al, 2018).…”

Alteration of wet and dry periods affects soil geochemical properties that drive contaminant availability and mobility. Consequently, the efficiency of soil remediation may vary, and thus soil management needs to consider these variations. This study reveals the effect of soil moisture manipulation on the behaviour of the toxic metalloids antimony (Sb) and arsenic (As) and the immobilisation efficiency of nanoscale zero‐valent iron (nZVI), biochar (BC) and BC modified by iron or iron/ferrous sulphide (nZVI‐BC and Fe/FeS‐BC). Soil samples from an abandoned Sb mining site were tested under laboratory conditions. Two distinct (organic and mineral) soil layers were incubated with each of the amendments (2% w/w application rate) at 50% and 100% water holding capacity (WHC) of the soils for 10 weeks, and subsequently extracted with demineralised water and rainwater. The immobilisation efficiency of the tested amendments was significantly influenced by the different soil moisture regimes and type of contaminant. Sorption onto secondary Fe minerals was the dominant Sb/As immobilizing mechanism. The iron‐based amendments showed up to 97% efficiency for Sb and up to 96% for As. However, Sb/As release was generally higher at 100% WHC and in the rainwater extracts compared to the other conditions, indicating that heavy rainfall and flooding of soils in‐situ may increase contaminant availability and mobility. In the organic layer, enhanced formation and leaching of metalloid‐DOC complexes and sorption competition of the negatively charged Sb/As species and DOC can be expected. Also, reductive dissolution of Sb or As‐bearing metal oxides could lead to the observed higher Sb/As release under flooded conditions, resulting in exacerbated environmental and health risks. Therefore, it is crucial to (1) improve the sorption characteristics of the tested amendments and/or develop other effective amendments for Sb/As immobilisation in different water regimes in soil; (2) test the amendments under real field conditions to evaluate the long term wet/dry exposure; and (3) develop proper risk assessment and soil remediation strategy for the study area and similar sites.

“…As the MRC soil is an agricultural floodplain soil and frequently influenced by tidal inundation, Sb may be released when solid phases (e.g., Fe-(oxyhydr)oxides) are reductively dissolved [20,21,35]. Frequent redox cycling influenced by wetting and drying cycles in this region may further enhance Sb sequestration by incorporating Sb into more crystalline phases [89,90].…”

“…Analyzing elements and their species requires more sophisticated analytical methods and techniques such as high performance liquid chromatography-inductively coupled plasmamass spectrometry HPLC-ICP-MS (Jabłońska-Czapla et al 2014b). Along with the development of analytical techniques allowing for the determination of lower and lower concentrations of analytes, a number of studies have been carried out on the content of antimony and its species in the environment (Ge et al 2013, Kozak and Niedzielski 2008, Wu et al 2022, Quiroz et al 2013, Zhang et al 2021). However, it is still unclear whether different sources of antimony have an influence on the ionic form in which it occurs in soil.…”

The aim of the study was optimization of antimony speciation methodology in soils in areas subjected to industrial anthropopressure from traffic, metallurgy and recycling of electrowaste (e-waste) sources. Antimony speciation was carried out using the hyphenated HPLC-ICP-MS (High-Performance Liquid Chromatography--Inductively Coupled Plasma-Mass Spectrometry) technique for the determination of antimony species ((Sb(III), Sb(V), SbMe 3 ). The extraction and determination of antimony species in soil was optimized and validated, taking into account the matrix effects. The best results in antimony extraction from soils were obtained using a mixture of 100 mM citric acid and 20 mM Na 2 EDTA. Ions were successfully separated in 6 minutes on Hamilton PRPX100 column with 0.11 μg/L, 0.16 μg/L, 0.43 μg/L limit of detection for Sb(III), Sb(V), SbMe 3 , respectively. The oxidized antimony form (Sb(V)) predominated in the soil samples. The reduced antimony form (Sb(III)) was present only in a few samples, characterized by the lowest pH. The methyl derivative of antimony (SbMe 3 ) was present in the samples with the lowest redox potential from the area around WEEE (Waste of Electrical and Electronic Equipment) treatment plant. The methodology of extraction and determination of three antimony species in soils was developed, achieving low limits of quantification and very good recovery. The research showed a large variation in antimony content in the soils impacted by type of industrial anthroporessure. The antimony content was the highest in the area of the WEEE treatment plant, indicating this type of industrial activity as a significant source of soil contamination with antimony.
