“…Iron is relatively immobile under most environmental conditions and generally has a very low bioavailability in soil (Hooda 2010), mainly due to the very low solubility of iron (III) hydroxide in its various forms. Chromium also was predominantly bound to the residual fraction, which may be linked to the preferential incorpo-rationofCrintothelatticeofsilicatesandprimaryoxidesminerals (Vithanage et al 2014; Arenas-Lago et al 2016). Chromium in soil is strongly retained by the solid phases and is generally poorly soluble and not mobile owing to its ionic properties (oxidation state and redox potential) (Alloway 2012).…”

This study investigated the concentration of potentially toxic elements (PTEs) including Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, Sb, V, and Zn in 102 soils (in the Near and Far areas of the mine), 7 tailings, and 60 plant samples (shoots and roots of Artemisia sieberi and Zygophylum species) collected at the Gol-E-Gohar iron ore mine in Iran. The elemental concentrations in tailings and soil samples (in Near and Far areas) varied between 7.4 and 35.8 mg kg−1 for As (with a mean of 25.39 mg kg−1 for tailings), 7.9 and 261.5 mg kg−1 (mean 189.83 mg kg−1 for tailings) for Co, 17.7 and 885.03 mg kg−1 (mean 472.77 mg kg−1 for tailings) for Cu, 12,500 and 400,000 mg kg−1 (mean 120,642.86 mg kg−1 for tailings) for Fe, and 28.1 and 278.1 mg kg−1 (mean 150.29 mg kg−1 for tailings) for Ni. A number of physicochemical parameters and pollution index for soils were determined around the mine. Sequential extractions of tailings and soil samples indicated that Fe, Cr, and Co were the least mobile and that Mn, Zn, Cu, and As were potentially available for plants uptake. Similar to soil, the concentration of Al, As, Co, Cr, Cu, Fe, Mn, Mo, Ni, and Zn in plant samples decreased with the distance from the mining/processing areas. Data on plants showed that metal concentrations in shoots usually exceeded those in roots and varied significantly between the two investigated species (Artemisia sieberi > Zygophylum). All the reported results suggest that the soil and plants near the iron ore mine are contaminated with PTEs and that they can be potentially dispersed in the environment via aerosol transport and deposition.

Microplastics pollution is becoming one of the most serious threats to the surface ecosystem of the earth; it is widespread in oceans, rivers, sediments, soils, and organisms. It is a growing concern as an environmental pollutant, which currently has no clear detection standard. Detection methods still need to be constantly supplemented and improved. This study explored a novel method called time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS) in this field. Four types of microplastics in farmland soils, namely, polypropylene, polyvinyl chloride, polyethylene terephthalate, and polyamide 6, were successfully identified in terms of particle size and abundance by combining the high molecular specificity with ion imaging capability of ToF‐SIMS. The procedure based on ToF‐SIMS analysis also provides a methodological reference and basic data for the investigation and research of microplastics in soil, coastal beaches, and sediment.

“…In addition, the preliminary sample treatment (freeze drying, air drying, oven drying, and others) also play a crucial role often leading to determination errors (van Hullebusch et al, 2005). Despite all these shortcomings described well in literature, the sequential extraction methods are widely used so far for evaluating the accessibility and mobility of metals in solid matrices (soils included) both in separate methods (Wisawapipat et al, 2017;Hasan et al, 2018;Minkina et al, 2018a;Al-Mur, 2020) and in combination with other instrumental identification methods (Scheinost et al, 2002;Hsu et al, 2015;Arenas-Lago et al, 2016;Mekapogu et al, 2018;Minkina et al, 2018bMinkina et al, , 2019. The present paper is aimed at a comparative evaluation of the results of Cu and Zn fractionation in Haplic Chernozem samples obtained by different sequential chemical extraction schemes to determine the most suitable version for specific features of soil without and with anthropogenic contamination.…”

This study is aimed at elucidating the fractionation of Cu and Zn in Haplic Chernozem and its alteration under the contamination to evaluate the extraction selectivity of different extractants and thus the efficiency of three sequential extraction schemes (Tessier and McLaren five-step and modified BCR three-step methods). General trends in the distribution of Cu and Zn speciations revealed with these three fractionation schemes suggest that they can be applied for the soils and the obtained results can be compared. Low mobility of potentially toxic metals (PTM) in the studied soil is suggested not only by their high content in residual fraction, but also by low contents of exchangeable and carbonate bound fractions (not more than 4-5 % Cu and 5-7 % Zn in the first two fractions). The highest contribution to the absorption and retention of Cu delivered from anthropogenic sources is made by organic matter and sesquioxides (up to 29 %); for Zn, by the nonsilicate Fe and Mn compounds (up to 25 %). However, the pattern of PTM extraction from soils varies during the application of different fractionation methods. The Tessier method is distinguished by a higher extractability relative to organic matter and sesquioxides. Therefore, this method is more informative for the contaminated soils. The McLaren method makes it possible to track the weakly bound species of compounds without the risk of involving other soil components. The BCR method is marked by simplicity of application and, therefore, recommended only for the noncalcic or low-calcic soils.
