Summary: The study found that lime and biochar remediation methods significantly reduced EEA, with only lime amendment resulting in increased exoenzyme C:P and N:P ratios. Among all factors, the relative abundance of Acidobacteria and bacterial Chao index, rather than available Cd content, accounted for the largest variations in soil EEA and EES.

Summary: This study investigated the HMs contamination and microbial community dynamics during a three-year revegetation of production Pb-Zn tailings in northern Guangdong province, China. The results showed that prolonged tailings stockpiling exacerbated Pb contamination, but revegetation effectively alleviated Pb. Pseudomonas emerged as a potential Pb remediator during the revegetation process.

Summary: This study introduces a soil for soil-remediation strategy using natural loess to convert into zeolite for remediating heavy metal polluted soil in the Chinese Loess Plateau (CLP). The synthesized zeolite shows excellent remediation performance for Pb(II) and Cu(II) polluted soil, effectively reducing the uptake and accumulation of these ions in vegetables with high removal efficiencies. This work paves the way for developing green and sustainable remediation eco-materials with local loess as raw materials.

Summary: A novel waste reclamation strategy has been developed for soil remediation, converting alkaline waste red mud into ferric oxide decorated zeolite for heavy metal polluted soil. The addition of Fe2O3-ANA effectively suppresses heavy metal mobility in soil and reduces bioaccumulation concentrations in harvested crops. The mechanism study identifies the adsorption and trapping of heavy metals in the zeolite structure via cation exchange process, providing a valuable approach for waste resource recycling and environmental conservation.

Summary: Nano zero-valent iron (nZVI) is one of the most studied nanomaterials for environmental remediation in the past 20 years. However, there have been few studies on the combination of nZVI with other materials, such as biochar, for enhanced soil remediation. This study found that the combination of nZVI and wood sawdust biochar (nZVI-BC) was more effective in immobilizing arsenic, lead, and zinc compared to pristine nZVI.

Summary: Soil heavy metal contamination caused by mining activities is a global issue that threatens public health. Biochar, as an environmentally friendly soil remediation agent, can effectively immobilize heavy metals. However, research on biochar remediation in mining areas is limited and the remediation effect is influenced by various factors. It is necessary to systematically unravel the knowledge of biochar remediation and provide guidance for future studies.

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: This study applies the concept of interfacial solar evaporation to heavy metal soil remediation. By using a tree inspired evaporator structure and coating it with reduced graphene oxide, the extraction of heavy metal liquids from soil is accelerated, leading to a high evaporation rate. Indoor tests and plant assays demonstrate the efficiency of this method in reducing heavy metal content in soil.

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: This study investigated the impact of plant- and animal-derived biochar on the competitive sorption-desorption of potentially toxic elements (PTEs) and phthalic acid esters (PAEs) in soils with different organic carbon content. The sorption behavior was influenced by biochar type, application dose, and soil organic carbon content. Additionally, the reciprocal effect between DEP and Cd2+ was found to be a crucial factor affecting their sorption/desorption behavior by biochar, with pig carcass biochar showing greater efficacy in metal/DEP immobilization.

Summary: This study investigates the long-term pollution characteristics of the Huafei River in Kaifeng, China, and finds that heavy metal concentrations in the river sediment are significantly higher than the background values in China. The potential ecological risk of the river is very high, especially in the midstream and downstream sections. Industrial activities, traffic sources, and natural sources are identified as the major sources of heavy metal contamination. It is crucial to control the pollution of Hg and Cd in order to prevent further damage to the ecosystem and human health.

Summary: The increasing quantity of biogas residues poses a threat to environmental protection and sustainable development. This study collected four different biogas residues and prepared biochar at different temperatures to evaluate their suitability. The results showed that higher temperatures resulted in higher biochar yield and improved physical and chemical properties. The structures of most biochars were more stable under high temperature. High temperature favored the formation of smaller micropores.

Summary: A series of magnetic Fe3O4@PDAn-CuxO composites with adjustable oxygen vacancies were successfully prepared by dopamine self-polymerization between Cu-Fe bimetallic composites. The catalysts exhibited excellent performance in degrading the antimicrobial contaminant triclosan (TCS) by activating peroxydisulfate. Fe3O4@PDA1.0-CuxO possessed the highest catalytic activity due to its high oxygen vacancies content. The catalyst showed great long-term stability and could be easily recovered by magnetic separation, making it a sustainable strategy for environmental-friendly remediation technologies.

Summary: A WO3/Bi5O7I direct Z-scheme heterojunction material was synthesized via a solvothermal-calcination method, which enhanced light absorption and charge carrier separation. The WB14 composite exhibited a significantly higher removal rate of rhodamine B compared to pristine Bi5O7I and WO3. Experimental parameters and stability of WB14 under simulated sunlight were investigated. The formation of Z-scheme heterojunctions between Bi5O7I and WO3 was proposed based on charge carrier migration and reactive species.
