Summary: This study aimed to evaluate the potential of microbial consortia and bacterial strains isolated from a soil with a history of pesticide application to degrade Trifluralin (TFL) in soil. Different bioremediation techniques, including biostimulation, bioaugmentation, and bioavailability enhancement, were considered to increase the effectiveness of TFL degradation. The results showed that the efficiency of TFL degradation varied among different techniques and bacterial strains. The most efficient strain was identified as Arthrobacter aurescens CTFL7, and the addition of a biodegradable compound, randomly methylated cyclodextrin (RAMEB), further enhanced TFL biodegradation.

Summary: This study demonstrates a novel E-Fenton system by magnetically decorating zero-valent iron (ZVI) onto a RuO2-IrO2/Ti electrode for efficient treatment of pharmaceutical wastewater. The ZVI serves as a sustainable source of Fe(II) for rapid removal of COD and TOC. The increase in BOD5/COD of the treated effluent highlights the enhanced biodegradability. The simultaneous formation of precipitation on the electrodes suggests the important role of coagulation process. The monitoring of nitrogen elements and by-products formation verifies the excellent capacity of the E-Fenton process for organic pollutants in pharmaceutical wastewater.

Summary: Recommended management practices can increase soil organic carbon, reduce greenhouse gas emissions, and maintain soil health in croplands. However, the impact of these practices on the soil organic carbon storage potential remains uncertain. A meta-analysis based on 2301 comparisons from 158 peer-reviewed papers was conducted to investigate the changes in soil organic carbon stocks induced by different management practices. Results showed that chemical fertilization combined with manure application, no-tillage, and straw return all led to significant increases in soil organic carbon stocks. The implementation of these practices is crucial for climate change mitigation and soil fertility improvement.

Summary: In this study, the corrosion status of steel rebars embedded in concrete with different cover thicknesses and exposed to a simulated marine environment was monitored using an embedded solid-state reference electrode. The results of electrochemical impedance spectroscopy confirmed the time of corrosion initiation for different concrete specimens. The relationship between free and bound chlorides were defined using the Temkin isotherm, and the time to crack initiation was predicted using the El Maaddawy model. This study successfully demonstrated the reliability of the solid-state MnO2 electrode for non-destructive monitoring of steel rebar corrosion in concrete.

Summary: This study investigates the performance of physically modified ball-milled kelp-seaweed biochar (KBCBM) in catalyzing the degradation of CIP-contaminated soil using peroxymonosulfate (PMS) and examines the phytotoxicity of the intermediates in the treated soil. The surface characterization of the KBCBM catalyst was studied using various instrumental analyses. The CIPsoil/KBCBM/PMS system showed excellent efficiency in CIP degradation (96.06%) under specific conditions. The presence of certain anions enhanced the CIP degradation, while other anions and organic matter had negligible effects. Reactive oxygen species formation was confirmed, and a non-radical reaction pathway was identified. The KBCBM/PMS system demonstrated promising potential for the treatment of CIP-contaminated soil.

Summary: This study investigated the efficiency of maize stalk biochar (MSB) in removing Cr(VI) from wastewater. Equilibrium isotherm results were analyzed using Langmuir, Freundlich, and Temkin isotherms. Freundlich and Temkin isotherm models exhibited good fit, with R-2 values of 0.994 and 0.909, respectively. The FT-IR bands revealed functional groups involved in binding Cr(VI) ions. SEM-EDS and TEM results provided insights into the morphology of the adsorbent and C/O ratio in MSB. XRD and XPS analyses indicated co-precipitation during adsorption. BET measurements characterized the surface and pore space of MSB. MSB showed a removal efficiency of 81% for hexavalent chromium ions in wastewater, and microbial fuel cells facilitated desorption with concurrent power generation of 359 mV.

Summary: In recent years, the issue of pathogens in the environment has gained widespread concern. New research has been conducted on removing pathogens and persistent pollutants from water. The study evaluated the effectiveness of the nanostructure copper-organic framework, HKUST-1, as a catalyst for eliminating Escherichia coli and generating sulphate radicals through peroxymonosulphate (PMS) activation. The disinfection process was optimized and achieved complete elimination of Escherichia coli growth after 30 minutes using a concentration of 60.5 mg/L HKUST-1 and 0.1 mM PMS. A novel development involving encapsulating HKUST-1 on polyacrylonitrile was proposed to overcome operational limitations and enable continuous treatment in a flow disinfection process.

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.
