Summary: Case studies demonstrate that using slag powder can mitigate soil liquefaction and reduce the lateral deformation of piles during earthquakes. The liquefaction resistance of soil is improved with an increase in slag powder content. Numerical modeling and finite element analyses confirm that slag powder effectively decreases the lateral deformation of piled in liquefiable soils. An empirical formula is proposed to evaluate the mitigation effect of slag powder on the lateral deformation of piles.

Summary: The study revealed changes in degradation, bioaccumulation, and accessibility of conazole fungicides after biochar addition to soil. The effects of biochar on pesticide degradation varied between different soil types, with a general reduction in uptake by earthworms and lettuce roots and leaves. The specific roles of biochar type and dose on pesticide fate remain unclear in this complex system.

Summary: Microcystins are highly phytotoxic to durum wheat, corn, white mustard, and garden cress, while leafy vegetables may bioconcentrate more microcystins in their edible parts. Human health risks from ingesting microcystins may be greater for leafy vegetables, but further research is needed to confirm bioconcentration levels in realistic environments.

Summary: The increasing rate of natural resource use leads to an increase in the anthropogenic load on the soil, mainly through industrial, metallurgical, and mining activities, as well as waste and drainage water from various enterprises. The accumulation of heavy metals in the soil negatively affects the soil bacterial community, which is crucial for its health. This review summarizes modern studies on the effect of heavy metals on soil bacterial communities using metagenomic methods and highlights the generally negative impact of pollutants on the taxonomic composition and diversity of bacterial communities, along with factors that modulate metal/metalloid toxicity.

Summary: The study evaluated the capability of native plant species grown in polluted post-mining soils to accumulate metals for phytoremediation. Different native plants were found suitable for remediation of specific metals, with some being effective for both Cd and Zn. However, none of the studied plants were suitable for phytoremediation of Pb, Cu, As, and Ag.

Summary: This work critically reviews stable isotope fractionation of various metals and metalloids in plants, providing basic principles and methodologies for non-traditional isotope analyses. The study finds that different biological and physico-chemical processes drive isotope fractionation in plants, and both biotic and abiotic factors can influence the process.

Summary: Metalloids pose potential hazards to plant systems, affecting crop productivity when present in high concentrations in soil. Phytoremediation methods aid in understanding molecular and biochemical mechanisms to deal with metalloid contamination. Recent advancements in proteomics and plant genomics help in understanding the role of transcription factors, metabolites, and genes in conferring metal tolerance.

Summary: This study examined the effects of soil microbial disturbance and maize plants on arsenic concentration and speciation in soil water. It was found that microbial disturbance increased the release of arsenic into soil water, especially for organic arsenic species. The abiotic sterilization of soil also increased arsenic release, but this effect was mitigated by the presence of maize in the pots.

Summary: This paper investigates the performance of energy piles in layered cross-anisotropic soils. The thermo-elastic fundamental solution of the soil is obtained using the extended precise integration method and is utilized as the kernel function in the boundary element method. The stiffness matrix equation for the energy pile, considering thermal strain and mechanical loads, is derived using the finite element method. The proposed method is validated through comparisons with in-situ tests and numerical simulations, and parametric analyses are conducted to discuss the influences of pile-soil stiffness ratio, length-diameter ratio, and soil cross-anisotropy on energy pile responses.

Summary: The provision of drains to geotechnical elements can reduce the shaking-induced excess pore pressure and loss of soil stiffness and strength. Shaking table tests were conducted on layered soil models to study the effectiveness of drained piles in reducing liquefaction hazards. The number of drains per pile and their orientation relative to shaking direction were evaluated based on porewater discharge, excess pore pressure, and de-amplification of ground motion. The study concluded that drained piles exhibit better performance in dissipation of excess pore pressure and stiffness improvement, with greater discharge capacity leading to higher performance. The improved performance is particularly useful for sloping ground with low-permeability layers.

Summary: This study investigated the arsenic concentrations and species in home-grown cage-free chickens collected from residents' backyards near the Shimen Realgar Mine in Hunan province, China. The predominant form of arsenic found in the chicken's muscle, stomach, liver, heart, and eggs was dimethylarsinic acid (DMA). Inorganic arsenic was the main species in the stomach skin, gastric contents, and feathers. Additional information about non-extractable and unidentified forms of arsenic was obtained through X-ray absorption near edge structure analysis. Overall, the estimated daily intake of arsenic from consuming chicken raised near the realgar mine was acceptable, and the corresponding hazard quotient values indicated minimal health risks for consumers.

Summary: This study evaluated the bioavailability, pollution, and eco-risk of heavy metals in surface sediments of Erhai Lake, with results indicating that BCR extraction is more efficient compared to HCl extraction. Cd was found to be the most polluted element, while Cr, Cu, and Ni were mainly natural in origin, and Cd, Pb, and Zn existed in both bioavailable and residue forms. Various assessment indices showed inconsistent eco-risks for different metals, highlighting the importance of integrating multiple indices in metal pollution and eco-risk assessments.

Summary: Mining activities can lead to severe heavy metal contamination in freshwater ecosystems, posing significant health risks. In this study, the concentration of heavy metals in water, sediments, and aquatic organisms was analyzed in the abandoned Shimen Realgar Mine area. The results revealed high levels of heavy metals in the mine area, primarily due to historical realgar-mining activities. The study also demonstrated species- and tissue-specific bioaccumulation of heavy metals.

Summary: The mining of ionic rare earth elements in Ganzhou has resulted in the destruction of vegetation in large areas of barren tailings. This study investigated the effects of soil additives combined with revegetation on the preservation of nutrients and microbial communities in the tailings. The results showed that the additives could buffer soil acidification, delay the loss of soil organic matter, and reduce the runoff loss of nitrogen compounds and sulfate. The bacterial diversity increased in some treatments, while fungal diversity remained unchanged. The microbial communities in the treatments showed closer interactions compared to the control group.

Summary: Different phosphates can affect the stability and bioavailability of As and Cd in soil. Aluminum phosphate, ferric phosphate, calcium phosphate, and potassium dihydrogen phosphate can improve the stability of Cd, but increase the concentration of unstable As. Both As and Cd can reach a relatively stable state in soil at pH 6.75. The critical point for controlling the relative stability of As and Cd in the sampled soil is a available P content of 450 mg/kg.

Summary: Bioaccumulation through diet is the main source of metal(loid)s in fishes. This study investigated the diet compositions of aquatic organisms and their potential food sources using stomach content analysis, stable isotope analysis, and a Bayesian mixing model. The results showed that aquatic organisms mainly obtained their nutrients from fine particulate organic matter and epilithon, with smaller contributions from leaf litter, coarse particulate organic matter, and fish.

Summary: This study investigated the community of sulfate reducing bacteria (SRB) in revegetated and bare tailings in Dingnan county, Jiangxi province, China. It was found that the SRB community in revegetated tailings had higher richness but lower evenness and diversity compared to bare tailings. At the genus level, Desulfovibrio was dominant in bare tailings while Streptomyces was dominant in revegetated tailings.
