Summary: This study evaluated the degradation, mineralization, and DBPs formation of the widely used herbicide metribuzin during aqueous chlorination. The results showed that DBPs formed during chlorination were more toxic than the precursor metribuzin, with increased toxicity effects on Anemia salina nauplii. Additionally, chlorinated solutions exhibited high estrogenicity to human receptors and mutagenic and developmental toxicant effects in BLYES and Q(SAR) tests.

Summary: Infrared matrix-assisted laser desorption ionization (IR-MALDESI) combines the advantages of electrospray ionization (ESI) and matrix-assisted laser desorption ionization (MALDI) and is a valuable tool for high-throughput screening (HTS) analysis. The optimized timing of the C-trap in IR-MALDESI can reduce ambient ion accumulation and maximize analyte ion accumulation. Additionally, this method can be used to measure intact antibodies in large molecules.

Summary: The presence of AgNPs during chlorination can impact the formation of DBPs in surface water sources. Higher AgNP concentrations led to increased specific formation rates of chloroform, which affected the THMFP rates and concentrations. The chlorine reaction time was found to be more effective in increasing the integrated toxic risk value of THMFP than the level of AgNPs.

Summary: This study evaluated the impact of exposure to poly-styrene nanoparticles (PS NPs) on the behavior, brain antioxidant activity, and DNA damage in male Swiss mice. It was found that mice exposed to PS NPs exhibited anxiolytic-like behavior and altered defensive response when confronted with a predator. Additionally, the exposure to PS NPs led to reduced brain antioxidant activity and increased DNA damage. These findings highlight the potential impact of PS NPs on mammals and underscore the ecotoxicological risks associated with their dispersion in natural environments.

Summary: In this study, the degradation of Dicamba methyl ester (DME) using a low-cost chlorine/ferrous process was investigated. Optimal conditions for DME degradation were determined using an artificial neural network (ANN) model and particle swarm optimization (PSO) algorithm, yielding a predicted yield of 88%. GC/MS analysis identified benzene, 1,2,4-trichloro-3-methoxy DME-BP as the only chlorine-containing byproduct. Total organic carbon (TOC) removal was analyzed using a Fenton-like process under optimized conditions, and toxicity assessments using Chlorella vulgaris microalgae indicated low toxicity of 20% when DME mineralization reached 62.52%.

Summary: The COVID-19 pandemic has caused unprecedented negative impacts. The potential effects of SARS-CoV-2 and microplastics in the aquatic environment are not well known. This study evaluated the ecotoxicological effects of exposure to SARS-CoV-2 and polyethylene microplastics in male adult Poecilia reticulata. The results showed behavioral changes, nephrotoxic and hepatotoxic effects, imbalances in ion homeostasis, and anticholinesterase effects induced by SARS-CoV-2 exposure. Polyethylene microplastic exposure caused genotoxic effects and increased enzyme activity. The combined exposure did not show synergistic effects. The study highlights the need for attention to the impacts of COVID-19 on aquatic biota.

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.
