Summary: This study comprehensively evaluated the remediation performance, degradation mechanism and overall assessment of lindane-contaminated soil using a mechanochemical method assisted by CaO. Experimental results showed that the mechanical activation of CaO to produce free electrons (e-) and the alkalinity of Ca(OH)2 were the main reasons for the degradation of lindane in soil. Dechlorination reactions, alkaline hydrolysis, hydrogenolysis, and carbonization were the main degradation pathways of lindane. The mechanochemical method with CaO was also effective in degrading other pollutants and the soil properties and toxicity were assessed after remediation.

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 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: Soil is a significant environmental matrix that supports the life of all creatures. However, human activities and population growth have caused soil pollution, releasing foreign substances and persistent contaminants. One common toxic substance is polycyclic aromatic hydrocarbons (PAHs), which can change soil characteristics, impact microbial biodiversity, and destroy items. The restoration and cleanup of PAH-polluted areas pose serious technological and environmental challenges due to the mutagenicity, carcinogenicity, and toxicity of petroleum hydrocarbons. This review discusses how PAHs affect soil characteristics and highlights the production of secondary metabolites and carbon dioxide during microbial breakdown processes. Additionally, the advantages of bioremediation strategies are assessed, emphasizing the importance of both legislative and scientific research.

Summary: The petroleum industry's development is driven by demand for petroleum and its by-products, but extraction and transportation processes may lead to soil contamination. Microbial remediation is a focus due to its convenience and low cost, although challenges such as inconsistent remediation effects and environmental consequences exist. Understanding pollutant sources, microbial degradation pathways, and influencing factors is crucial for selecting optimal remediation strategies.

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: In recent years, China has relocated enterprises and industries associated with intense pollution, which has resulted in abandoned polluted sites. The study reveals that among the surveyed soil stabilization projects, 29% are chemical industry sites and 96.7% of these sites are heavily polluted with heavy metals and metalloids. Landfilling is the primary strategy for soil disposal following stabilization, and the reuse of treated soils is preferred to landfill waste treatment.

Summary: The production and disposal of plastics have raised concerns for the sustainability of the planet. Plastic waste often ends up in landfills or is released into the environment, leading to the generation of microplastics. Terrestrial ecosystems are equally at risk of microplastic contamination, which comes from various sources such as plastics mulch, pharmaceuticals, tire abrasions, textiles industries, sewage sludge, and plastic dumping. Microplastics can interact with existing pollutants, delaying their degradation process and affecting soil health and fertility. This article aims to explain the detrimental impact of microplastics and their interactions with other pollutants in the terrestrial ecosystem, specifically focusing on their effects on soil sustainability.
