Summary: The development of a magnetized activated carbon adsorbent with improved separation efficiency for the removal of antibiotics from water was studied. The adsorbent exhibited competitive adsorption properties between TC and LM, and the process was endothermic. Non-isothermal fitting of the data into different adsorption models provided insights into the adsorption behavior of the system. Redlich-Peterson isotherm accurately predicted TC adsorption data at different temperatures, while the extended Langmuir model accurately predicted the binary adsorption system.

Summary: A magnetic N-doped sludge biochar (MNSBC) was synthesized for efficient removal of zwitterionic tetracycline (TC) from water. MNSBC showed a maximum adsorption capacity of 197.3 mg/g at 298 K and achieved high removal rates of TC in various environmental waters. The adsorption process of TC onto MNSBC was described by Elovich and Freundlich models, and the main mechanisms involved Lewis acid-base, 7C-7C conjugation, electrostatic interactions and pore filling. MNSBC also exhibited low release levels of iron and total nitrogen, making it suitable for water treatment applications.

Summary: With numerous legacy metal mine sites in Japan, there is a growing need to transition to more sustainable and economical acid mine drainage (AMD) treatment methods. This study focused on the Fe-removal performance of a large-scale microbiological passive treatment plant and the disposal of its resulting Fe-sludge waste. The Fe-sludge was found to be an effective adsorbent, particularly for As(V), and the usability of the Fe-sludge was more favorable for As(V) compared to As(III).

Summary: This study explores the influence of coal fly ash (FA), wollastonite (WO), pumice (PM), and metakaolin (MK) as fillers on the rheological, mechanical, chemical, and mineralogical properties of a magnesium potassium phosphate cement (MKPC) used for encapsulating radioactive wastes. Various pastes and mortars of MKPC were investigated, and parameters such as workability, compression strength, dimensional stability, pH, chemical composition, and mineralogical properties were analyzed. The results showed that the fillers had minimal chemical impact on the MKPC system, and all formulations with a water/cement mass ratio of <0.65 exhibited high compressive strengths and pH values in the passivation zone of aluminum corrosion after 90 days.

Summary: The objective of this study was to investigate the behavior of bentonite as a barrier material in a high-level radioactive waste disposal system. Experimental results showed that the main component of bentonite remained as sodium montmorillonite without any structural changes. In a dry and high temperature condition, the expandability of smectite was not fully developed, but it recovered when hydrated with liquid water. Solubilized ions were transported towards the heater and concentrated in two distinct areas. The microstructure of bentonite near the heater exhibited dense packets with carbon and Na-S-coated cavities, and precipitation of calcite and calcium sulfates also occurred.

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.

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.
