Summary: A two-phased bench-scale study evaluated the potential use of various sorbents for chemical stabilizing agents in the solidification/stabilization treatment process of PFAS contaminated soils. Results indicated that GAC showed the highest sorption performance for PFAS compounds, significantly reducing leachability, suggesting its effectiveness in immobilization of PFAS contaminants in soil.

Summary: Soil pesticide contamination caused by modern agriculture is a significant global issue. Biochar, as a renewable and economical carbonaceous material, provides a natural solution for immobilizing pesticides and improving soil health. However, its impact in agricultural contaminated soil is influenced by various factors, which require further research on mechanisms and controlling factors.

Summary: Petroleum contamination in soils is a global problem that seriously threatens environmental safety and human health. Recent studies have shown that bioelectrokinetic and bioelectrochemical remediation techniques are feasible and environmentally friendly methods for removing petroleum contaminants from soils. This review summarizes the progress and development of these technologies, including their working principles, removal efficiencies, influencing factors, and limitations. The potentials, challenges, and future perspectives of these technologies are also discussed to promote their widespread implementation on a large scale.

Summary: This review discusses the application of biochar in remediating petroleum hydrocarbon-contaminated soils, focusing on its potential as a biostimulation agent to enhance the degradation of hydrocarbons in soil. Biochar may increase degradation efficiency by enhancing microbial biomass. While biochar shows promise in remediating hydrocarbon-contaminated soils, there are still key questions that need to be addressed.

Summary: The accumulation of toxic and persistent lindane in soil landfills poses a risk of leaching and contamination of surrounding rivers. A simple and cost-effective composite consisting of magnesium oxide (MgO) and activated carbon (AC) has been proposed to remove lindane in soil and water. The use of MgO provides a basic pH and allows for the total adsorption of heavy metals in contaminated soils, while AC provides sites for lindane adsorption and a reductive atmosphere. This composite has shown highly efficient remediation capabilities, allowing for the elimination of lindane and immobilization of heavy metals.

Summary: This study aims to evaluate the effectiveness of the integrated approach combining surfactant-assisted soil washing and cork granules for removing lindane from contaminated soil. The results show that cork granules can efficiently retain lindane and that soil washing with surfactants can separate lindane from soil. However, the integration of both treatments is not as efficient as expected and hinders the sorption of lindane.

Summary: This study is the first to investigate the removal of different classes of pesticides from soil using ozonation as a remediation technique under field conditions. The results suggest that ozonation has potential as a credible alternative technology for remediating pesticide polluted soils, particularly when dual application is used.

Summary: This study comprehensively analyzes and evaluates geogenic arsenic contamination in excavated soils worldwide, and provides an overview of management and mitigation methods. The study found that arsenic levels in excavated soils exceed regulatory limits, posing a threat to the environment and human health. While there are numerous arsenic remediation techniques, specific measures are required for geogenic arsenic contamination in excavated soils. Furthermore, the suitability and effectiveness of most conventional and advanced remediation techniques need further exploration.

Summary: This study determined the most effective surfactants for remediating gasoline and diesel-contaminated soil by integrating soil texture and organic matter information. Anionic surfactants showed better removal rates for hydrocarbons compared to non-ionic surfactants, with results suggesting preferential desorption on different hydrocarbon ranges.

Summary: Solids contaminated with per- and polyfluorinated alkyl substances (PFAS) pose significant environmental pollution. This study investigates the use of ultrasound to desorb and degrade PFAS in soil, finding that ultrasound treatment can significantly reduce PFAS concentrations but does not achieve significant degradation.

Summary: Machine learning was used to predict the important factors affecting phytoextraction efficiency of hyperaccumulators. Heavy metal properties, especially the metal ion radius, were found to be the most important factors, while the plant family had the most influence on the bioconcentration factor, metal extraction ratio, and remediation time. The Crassulaceae family showed the highest potential as hyperaccumulators, related to gene expression and substance secretion. The insights from the machine learning model interpretation could guide efficient phytoremediation.

Summary: A new Liquid Activated Carbon (LAC)-enhanced microwave (MW) treatment method for the remediation of PAH-contaminated soils was studied. The role of different doses of LAC was investigated, and it was found that LAC significantly increased the absorption capability of the MW electric field, resulting in high soil temperatures and shortened removal kinetics of PAH. The mobility of LAC was also tested, and it was shown to have good mobility when applied by gravity-driven percolation.
