Summary: Remediation of hydrophobic organic contaminants using activated carbon is effective, but current laboratory experiments may overpredict the extent or speed of remediation compared to field conditions. In this study, the bioaccumulation of DDT, DDD, and DDE residues by earthworms exposed to laboratory-aged or field-aged soils was compared, and the results showed that activated carbon significantly reduced the bioaccumulation of DDX in earthworms in both laboratory and field conditions. However, the rate of reduction was faster in laboratory-aged soils compared to field-aged soils, indicating differences in temperature and activated carbon incorporation methods between the two may impact the effectiveness of remediation.

Summary: Enhanced diesel removal from contaminated soil was achieved by using micro-bubbles and selected surfactants based on their solubilization properties and decontamination capacities. The use of a mixture solution of saponin and cyclodextrin, as well as micro-bubble enhancement, significantly increased diesel removal efficiency. Moreover, a 90-minute flushing time with circulation of flushing solution effectively ensured the cleaning goal while retaining soil solute for residual diesel biodegradation.

Summary: Arsenic is a harmful and widespread groundwater contaminant. Laboratory-scale studies have found that the joint addition of nitrate and Fe(II) can form magnetite and reduce dissolved arsenic concentrations in polluted coastal aquifers. Phosphate concentrations and salinity do not affect the remediation efficiency of this method.

Summary: This study investigates the performance of two non-ionic sugar-based surfactants in enhancing the solubilization and mass transfer of strongly adsorbed hydrophobic organic compounds in porous media. The experimental results showed that both surfactants effectively increased the solubilization of the contaminants and the biosurfactant exhibited the greatest solubilization ability.

Summary: The accumulation of multiple organic pollutants in the soil poses a huge threat to ecological systems and human health. Iron-based catalysts, known for their environmental friendliness, wide applicability, and low cost, are commonly used in sulfate radicals-based advanced oxidation processes for soil remediation. This paper focuses on the progress of Fe-based catalysts in the treatment of organically contaminated soil using advanced oxidation processes. It discusses the activation process of persulfate and the generation of free radicals for soil remediation. Additionally, it explores the changes in physicochemical properties of soil after treatment and investigates the challenges associated with the use of Fe-based catalysts in soil remediation.

Summary: The remediation of industrial site soil using Fe2+ chelated with sodium citrate activated persulfate oxidation (PS/Fe2+/SC) was investigated. The study found that the maximum removal rates of sigma 16 PAHs in Nanjing site soil (NJS) and Hefei site soil (HFS) were 73.6% and 85.8% after the second-stage oxidation, respectively. However, the efficiency of PAHs degradation did not increase in the later oxidation stages due to the presence of high crystalline Fe mineral phases in both NJS and HFS, which hindered the Fe2+/Fe3+ recycle and inhibited the production of reactive oxygen species during the remediation process.

Summary: Biochars have been shown to effectively reduce PFAS leaching in contaminated soils. This study produced and tested eight different waste timber biochars, with varying activation levels and production methods. The results suggest that the sorption capacity of biochars is influenced by activation degree, temperature, and soil organic carbon content.

Summary: The study demonstrated that cyclodextrins can enhance the desorption efficiency of petroleum hydrocarbons (PHs) in contaminated soil. The optimal desorption conditions were determined using batch desorption experiments and response surface methodology analysis. Cyclodextrins have great potential as a solubilizer for in-situ removal of PHs in petroleum-contaminated sites.

Summary: In this study, the feasibility of carbon-coated nZVI (Fe-0@C) as a persulfate (PS) activator to degrade anthracene (ANT) in soil was investigated. The results showed that the Fe-0@C/PS system had a good removal effect on ANT in the soil, and the effectiveness was consistent across different pH ranges. The study also revealed the mechanism of action of superoxide radicals (O-2(center dot-)) and singlet oxygen (O-1(2)) in the removal of ANT, and proposed a possible degradation pathway for ANT, filling the knowledge gaps in the application of nZVI in soil remediation.

Summary: The efficient remediation of PFAS-contaminated soils is increasingly important due to the growing awareness of these chemicals. The choice of remediation techniques depends on the soil's composition, particularly the clay content. This study investigated the mobilization efficiency of PFAS in soils with varying clay contents using electrokinetic remediation and hydraulic flushing techniques.

Summary: The study on controlling nucleation rate in continuous ultrasonic processes found that ultrasound-assisted nucleation process is presumably dominated by secondary nucleation. Parameters such as supersaturation, residence time, and flow rate also have a strong influence on nucleation rate. Additionally, the influence of ultrasonic power is crucial but levels off once a certain amount is reached.

Summary: In this study, a new heat-mixing model based on heat distribution measurement after an applied heat pulse is proposed to predict mesomixing and support scale-up, scale-down, design, and optimization of batch reactors. The model considers various factors, and a strong correlation between the mixing time of the heat pulse method and the mass-transfer coefficient of the mixing-sensitive Bechamp reaction was observed.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
