Summary: This study evaluates the integration of activated sludge process with biological Fenton reaction to enhance the treatment of antibiotics in wastewater. The research findings demonstrate that the anaerobic/aerobic sequencing batch reactor (SBR) with magnetite achieved stable and enhanced removal of sulfamethoxazole (SMX) compared to the reactor without magnetite. The presence of magnetite facilitates the generation of hydroxyl radicals (.OHs) and microbial Fe (III) reduction, resulting in improved removal efficiency of SMX and chemical oxygen demand (COD).

Summary: The study evaluated the oxidative removal of methylene blue from synthetic textile wastewater using a combination of persulfate and heterogeneous Fenton-like process. The optimal conditions for MB removal were determined, and it was found that H2O2 and goethite doses greatly influenced the efficiency of MB removal. Reusing goethite for 5 cycles still maintained a high MB removal efficiency of 93%, indicating its good reusability. Radical trapping experiments identified hydroxyl radicals as the dominant radical for MB removal.

Summary: This study evaluated the electrochemical oxidation of gaseous streams polluted with benzene, toluene, and p-xylene using a jet mixer and electrochemical cell device. The technology achieved an efficiency of 14% in hydrogen peroxide production at atmospheric pressure and 12 degrees C.

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.

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.
