Summary: The addition of Chlorotetracycline (CTC) to cattle manure composting systems hindered the removal of antibiotic-resistant genes (ARGs) and increased the relative abundance (RA) of certain ARGs and mobile genetic elements (MGEs). High levels of CTC had a more persistent effect on bacterial community and Firmicutes and Proteobacteria were identified as the main hosts for ARGs based on network analysis. The presence of CTC increased the risks of spreading ARGs in compost products.

Summary: This study investigated the degradation of chloramphenicol (CAP) during electrochemical treatment using Ti/PbO2-La electrodes. The doping of La improved the performance of the electrode, and the degradation rate of CAP increased with current density. The electrolyte concentration, current density, and pH value had an effect on CAP degradation and total organic carbon (TOC) removal. The degradation products of CAP could alter bacterial community and ARGs in the environment.

Summary: This study investigated the dynamics and driving mechanisms of antibiotic resistance genes (ARGs) in three different organic solid waste (OSW) composts. The dominant ARGs varied among the different OSWs. The abundance of ARGs was generally similar in all final composts, attributed to the similar bacterial community. Thermophilic aerobic composting can inhibit vertical gene transfer (VGT) in pig manure and horizontal gene transfer (HGT) in sludge, but it increases HGT in kitchen waste, resulting in a significant increase of ARGs in kitchen waste compost.

Summary: We investigated the efficiency and mechanism of electrochemical treatment in removing antibiotic resistance genes (ARGs) from bacteria isolated from hospital wastewater. We found that the removal efficiency of ARGs increased with higher voltage and longer electrolysis time, with the optimal treatment conditions being 3 V and 120 min. Scanning electron microscopy and flow cytometry revealed that electrochemical treatment altered the cell membrane permeability and induced different levels of apoptosis and necrosis. Compared with traditional disinfection methods, electrochemical treatment had lower potential risks, such as reduced bacterial conjugative transfer frequencies and minimal conversion of intracellular ARGs to extracellular ARGs.

Summary: This paper reviews the mechanisms of antibiotic and antibiotic resistance gene (ARG) removal in constructed wetlands (CWs) and the influence of different substrates. The study found that substrates primarily remove antibiotics and ARGs through adsorption, biodegradation, chemical oxidation, and filtration. Zeolite showed better removal performance than gravel for antibiotics and intracellular ARGs due to enhanced substrate adsorption, filtration, and biodegradation. Mn ore also demonstrated high capability for removing high concentrations of antibiotics. Furthermore, combined substrates of soil/sand/gravel and other substrates facilitate antibiotic removal. Future research should focus on exploring competitive adsorption, redox-controlled biodegradation, the role of Fe/Mn oxides in chemical oxidation, and evaluating extracellular ARG removal with different substrates in CWs.

Summary: Microplastic pollution is a global environmental issue that is on the rise. Research has shown a significant correlation between microplastics and antibiotic resistance genes (ARGs), with chicken farms being potential hotspots for the co-spread of microplastics and ARGs. Experimental results indicate that microplastics enhance the transfer of ARGs between bacteria, potentially through the regulation of specific genes. These findings highlight the co-occurrence of microplastics and ARGs in the agricultural environment, and the role of microplastics in exacerbating the prevalence of ARGs.

Summary: This study investigated the distribution of antibiotic resistance genes (ARGs) and bacterial communities in air, water, and soil within a watershed area. Different types of ARGs were found dominant in different environmental media, and shared genes and bacteria were consistently detected in all samples. Co-occurrence network analysis revealed the co-occurrence module of resistance genes, mobile genetic elements (MGEs), and potential bacterial hosts. A risk assessment framework based on ARGs abundance, detection rate, and mobility identified high-risk ARGs.

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.
