Summary: Amplified hygiene and precautionary measures are necessary to control COVID-19, but may lead to increased use and discharge of disinfectants, particularly quaternary ammonium compounds (QACs). This review discusses the classification and mechanism of disinfectants, with a focus on QACs, and highlights the occurrence, fate, toxicity, and antimicrobial resistance associated with QACs. Evidence shows a significant rise in the mass load of QACs at wastewater treatment plants and higher concentrations in residential dust during the pandemic, posing potential risks to human health and the environment.

Summary: Conductive hydrogels have great development prospects in flexible strain sensors, but long-term direct contact with human skin can cause bacterial infection. A hydrogel with antibacterial, biocompatibility, and toughness was designed and manufactured using a freeze-thaw method. The hydrogel maintains tensile properties and fatigue resistance at low temperatures and is resistant to bacteria. Therefore, hydrogel sensors can be used to monitor human movements.

Summary: In this study, an antimicrobial packaging material was successfully developed by melt processing blends of high-density polyethylene (HDPE) and chitosan (CS). The effect of chitosan content (up to 40%) and the addition of quaternary ammonium salt functionalized chitosan (CS-CTAB) as an additive were evaluated. The results showed that HDPE/CS composites with 10% and 20% chitosan exhibited better elongation values and higher thermal stability, and the additive acted as an antimicrobial agent, making the composites suitable for food packaging.

Summary: The study found that M80 resin has the best removal efficiency for OMPs in drinking water treatment, but it is vulnerable to the presence of humic acid. In contrast, D205, D213, and NDMP-3 resins are less affected by humic acid. Additionally, D205 has the highest efficiency in reducing DBPs and can be a selective resin for areas with high bromide content in drinking water treatment.

Summary: The study investigated non-point source pollution in the Dan River watershed, finding that nitrogen loads were higher during the wet season and that vegetation restoration and agricultural management could reduce nitrogen pollution. Increasing forestland and reducing fertilizer use and irrigation in the watershed were shown to decrease nitrate and NH4+-N loads. This highlights the importance of reasonable land planning and agricultural management in controlling non-point source pollution and ensuring river water quality.

Summary: UV/chlorine treatment enhances the kinetics and efficacy of cell membrane or DNA damage to B. subtilis compared to UV irradiation or chlorination alone. The in-situ generation of radical species HO center dot and Cl center dot around intracellular DNA might contribute to these enhancements. The study provides surrogate indicators for determining the minimal chlorine dose for effective inactivation of bacteria during UV/chlorine treatment by using CTFAC values and decreasing UVA254 levels.

Summary: Although tertiary wastewater treatment processes (TWTPs) have high removal efficiency for chemical pollutants, their impact on microbial risk mitigation is uncertain. This study used metagenomic approaches to investigate the changes of antibiotic resistance genes (ARGs), virulence factor genes (VFGs), and their co-occurrence during multiple TWTPs. It was found that the denitrifying biofilter (DB) increased the abundance of antibiotic-resistant bacteria and ARGs, as well as the relative abundance of ARGs and VFGs through the enrichment of multidrug resistance and offensive genes. Complementary microbial risk reduction was achieved through ultraviolet and constructed wetland treatment. The study provides new insights into the effects of TWTPs on the antibiotic resistome and VFG profiles, and aids in selecting appropriate TWTPs for microbial risk mitigation.

Summary: Halophenolic disinfection byproducts (DBPs) are emerging pollutants that have adverse effects on human cells and need further exploration of molecular mechanisms. Substituting halophenolic DBPs with the same halogen leads to greater cytotoxicity when there are more substitution sites. Iodophenols are the most toxic, followed by bromo-phenols and chlorophenols when substituted at the same sites. Some of these DBPs showed significant endocrine-disrupting effects at sublethal concentrations.

Summary: This study used size exclusion chromatography (SEC) coupled with multiple detectors to analyze the dissolved organic matter (DOM) in the Yangtze River and its tributaries. The results showed that the DOM mainly consisted of proteinaceous biopolymers and humic substances. A characteristic fulvic-acid-like fluorophore was found in downstream tributaries, which originated from the discharge of residual naphthol and naphthylamine moieties in biologically treated textile wastewater. The occurrence of this fluorophore in the Yangtze River main stream suggested that the discharge of textile wastewater had altered the optical properties of riverine DOM, emphasizing the importance of advanced treatment processes.

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.

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.
