Summary: In this study, an adapted compost was used to treat complex, toxic, and aged landfill leachate. High removal efficiencies of organic matter, copper, and iron were achieved after pretreatments and the biologic process with compost. The analysis of microbial assemblages in compost samples revealed certain resilient genera and relevant metabolisms for pollutant removal.

Summary: The aim of this study was to investigate the effects of fertilizing Bromopsis inermis and Phalaroides arundinacea plants with sewage sludge compost (SSC) on biomass yield and quality. The results showed that using SSC as a fertilizer had poor performance. Although fertilizing with SSC significantly increased the biomass yield of Ph. arundinacea, it also increased the concentration of heavy metals in the soil.

Summary: This study systematically investigated the performance of sulfidated zero-valent iron (S-ZVI) in immobilizing lead, cadmium, and arsenic in contaminated soils. The results showed that S-ZVI could effectively immobilize and transform these heavy metals into less mobile forms, reducing their phytoavailability. Furthermore, S-ZVI was found to prevent the remobilization of heavy metals under changing soil redox conditions. Therefore, S-ZVI shows great potential as a remediation amendment for soils contaminated with multiple heavy metals.

Summary: Improper disposal of heavy metal-contaminated iron ore tailings poses a significant risk to the surrounding environments. Adding compost could reduce heavy metal accumulation in ryegrass and promote plant growth. The high concentration of organic matter in compost treatments likely enhanced the mobilisation of Cu and Zn for plant uptake.

Summary: The study demonstrated that mixed bacteria-loaded biochar effectively immobilized As, Pb, and Cd in soil, increased soil pH and dehydrogenase activities. Pb was mainly immobilized by co-precipitation, while Cd was adsorbed through precipitation formation and ion exchange with the biochar. Synergistic reactions between anions and cations also contributed to the immobilization of heavy metals.

Summary: The study investigated the use of recycled food waste ash as a heavy metal adsorption material and the application of in situ electrokinetic techniques and acetic acid for eco-friendly remediation. Results showed good removal efficiency for heavy metals after 10 days of operation, but further experiments are needed after longer periods of operation before electrode exchange.

Summary: This study examined the possibility of converting the organic fraction of municipal solid waste into mature compost using the composting bin method. The results indicated that the addition of animal and poultry manure in the composting process met the acceptable standards for temperature, pH, and EC. After microbial activity, the organic matter content and C/N ratio decreased. Treatment with additives such as biocont and humic acid, as well as agricultural waste, reduced organic matter loss. Composting with animal and poultry waste showed higher nutrient levels at the mature stage.

Summary: Gallbladder cancer (GBC) is a deadly malignancy with limited treatment options. The role of arsenic (As) in GBC carcinogenesis is debated, and there are no data on As measurement in GBC samples. This pilot study measured As concentrations in GBC tissue samples compared to non-cancerous gallbladder (NCGB) samples and found higher levels of arsenic in GBC samples, suggesting a potential impact of arsenic on GBC and the need for further studies.

Summary: The addition of sewage sludge biochar significantly improved soil characteristics, plant growth and nutrient content. The concentration of heavy metals in tomato tissues was low, with traces of some metals found in roots only. The addition of biochar also led to a decrease in the concentration of arsenic and lead in tomato fruits.

Summary: Rare-earth elements (REEs) serve as sensitive tracers for evaluating groundwater interaction with materials for contaminant remediation, with zero-valent iron and organic carbon mixtures effectively reducing contaminant concentrations. The solid-phase partitioning of REEs increases with pH in ZVI systems, while unexpected negative europium anomalies were observed in organic carbon PRBs, providing new insights into redox conditions in treatment zones. REE concentrations and shale-normalized profiles are valuable natural tracers for understanding in situ technologies for groundwater remediation.

Summary: Per- and polyfluoroalkyl substances (PFAS), as anthropogenic organic pollutants, are widely distributed in the aquatic environment and have adverse effects on human health and ecology. This review critically evaluates the global occurrence and distribution of PFAS in water and discusses the evolving regulatory responses to mitigate the risks associated with PFAS. The study highlights the need for international cooperation in managing PFAS contamination.

Summary: Permeable reactive barriers (PRBs) are widely used for groundwater remediation at contaminated sites, but there is still a lack of understanding regarding their performance and the mechanisms involved. The role of ZVI corrosion in the remediation of pollutants and the interaction between contaminants and ZVI in PRBs are not well understood. This review paper aims to clarify these mechanisms and highlight the importance of ZVI corrosion products and mineral precipitates in the long-term performance of PRBs. Further development of characterization tools and models is necessary for effective PRB design.

Summary: Globally, lead (Pb) contamination is a significant issue affecting public health. This study examines the concentrations and isotopic data of Pb in a Pb paint production facility and its surrounding areas. The findings suggest that pollution from the facility has impacted offsite soils, but determining the exact sources of lead contamination is challenging due to overlapping isotopic signatures. An integrated approach that considers site characterization and historical activities is important for determining source attribution.

Summary: The review of literature on reported sorption coefficients of eight anionic PFAS in soil revealed significant associations between soil cation content (calcium and sodium) and PFAS sorption, while organic carbon content was significant only at elevated levels. Discrepancies between laboratory and field studies suggest that critical aspects of PFAS sorption may be overlooked in laboratory experiments. Future studies would benefit from standardized analytical methods and appropriate soil parameters for more accurate predictions.
