Summary: Both heavy metals and radiation can impact the proliferation and dissemination of emerging antibiotic resistance pollutants. The profile of antibiotic resistance in uranium mines, which are rich in radioactive metals, is largely unknown. This study investigated the distribution and influencing factors of antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) in a uranium mine in Guangdong province, China. The findings demonstrate the occurrence of ARB and ARGs in uranium mines for the first time, which contributes to assessing and controlling the ecological risk of antibiotic resistance in radioactive environments.

Summary: Antibiotics are commonly used in aquaculture to prevent and control diseases, but their overuse leads to the development of antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs). The presence and transfer mechanisms of antibiotics, ARB, and ARGs in water, sediment, and aquaculture organisms are summarized in this paper. The key mechanisms of antibiotic resistance in bacteria include changes in cell membrane permeability, antibiotic efflux enhancement, and structural changes in antibiotic target proteins.

Summary: This study compared the effects of heap composting and thermophilic composting on antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs) in livestock manure, finding that ARGs abundance significantly increased in heap composting while decreased in thermophilic composting. Bacterial hosts were associated with variations in ARGs and MGEs, with different bacterial communities playing different roles in the two composting methods.

Summary: Starvation in activated sludge has an impact on the abundance of antibiotic resistant bacteria and antibiotic resistance genes. Carbon starvation reduces the abundance effectively, while anaerobic-aerobic starvation mitigates the abundance significantly. These findings provide guidance for controlling antibiotic resistance risk in wastewater treatment plants.

Summary: In order to combat the spread of antibiotic resistance in the environment, managing wastewater effluent treatment effectively is crucial for the simultaneous removal of antibiotics, antibiotic resistant bacteria (ARB), and antibiotic resistance genes (ARGs). Researchers have developed a multifunctional electroactive poly(vinylidene fluoride) ultrafiltration membrane that not only retains ARB and ARGs effectively but also demonstrates high oxidation capacity as an electrode. The membrane has shown excellent degradation efficiency of sulfamethoxazole and significant inactivation of ARB during both anode and cathode filtration processes. Furthermore, the membrane is more efficient in degrading intracellular ARGs located in the genome compared to those located in the plasmid. The electroactive ultrafiltration membrane has also exhibited improved antifouling properties and feasibility for practical application in treating wastewater effluent.

Summary: The prevalence of micropollutants and antibiotic resistance in aquatic environments is a growing concern for public health and ecological security. Conventional wastewater treatment processes have limited efficiency in removing these contaminants, leading researchers to propose photocatalytic processes as a promising solution. In this study, the photocatalytic performance of a urea-based graphitic carbon nitride was evaluated for simultaneous removal of multiple pollutants and antibiotic resistant bacteria. The results show that this material has significant effectiveness in removing pollutants and antibiotic resistance, making it a potential candidate for wastewater treatment.

The results showed that the consortia had great resistance to SDZ but were heavily affected by CTC. The presence of ARGs, particularly in Ca. Brocadia bacteria, played a significant role in the resistance mechanism.

Summary: The abundance of antibiotic resistance genes and resistant bacteria in the environment poses a risk to health, but a quantitative risk assessment approach for these genes and bacteria shows high unpredictability. Therefore, it is proposed to categorize these genes and bacteria as a new type of emerging contaminants and incorporate evolutionary concepts into modern risk assessment.

Summary: The presence and persistence of antibiotic resistance genes (ARGs) in wastewater treatment plants (WWTPs) are of growing concern due to their potential risk to human health and ecological safety. Additionally, the concentration of heavy metals in sewage and sludge may contribute to the co-selection of ARGs and heavy metal resistance genes (HMRGs). In this study, metagenomic analysis was used to characterize the profile and abundance of antibiotic and metal resistance genes in influent, sludge, and effluent samples. The results showed that various ARGs and HMRGs were present in all samples, with the influent containing a higher number of resistance genes compared to the sludge and effluent. Biological treatment resulted in a significant reduction in the relative abundance and diversity of ARGs, but complete elimination was not achieved. Furthermore, potential pathogens were detected, and their relative abundances remained unchanged. Therefore, more specific measures are needed to control the proliferation of ARGs and HMRGs in the environment. This study provides valuable insights into the removal of antibiotic resistance genes during sewage treatment through metagenomic sequencing.

Summary: This study discusses the occurrence and proliferation of antibiotic resistance in wastewater treatment plants, the factors influencing antibiotic resistance bacteria and genes, the tools to assess antibiotic resistance, the environmental contamination of antibiotic resistant bacteria and genes from wastewater treatment plants, the effects on human health, and treatment strategies. Resistant bacteria such as Enterobacteriaceae, Pseudomonas aeruginosa, and Escherichia coli exist in various processes of wastewater treatment plants due to the high concentration of antibiotics in wastewater. Improving wastewater treatment technology and avoiding antibiotic misuse are critical to overcome the threat of antibiotic resistance. Factors such as abiotic factors and organic loads can affect the development of antibiotic resistance bacteria and genes in wastewater treatment plants. Molecular methods such as DNA sequencing and real-time PCR can be used for rapid characterization and detection of antibiotic resistance bacteria and genes. Reusing wastewater effluent for irrigation is an efficient method to overcome water scarcity, but it may also pose potential environmental risks such as increased antibiotic resistance in soil microbiome. Treatment technologies like anaerobic and aerobic treatment, coagulation, membrane bioreactors, and disinfection are considered potential techniques to restrict antibiotic resistance in the environment.

Summary: This study investigated the removal of antibiotic resistance genes (ARGs) in an industrial-scale pig manure management system and discussed the implications of mobile genetic elements (MGEs) and microbial community structure. The results showed that composting partially removed certain ARGs and MGEs, indicating that complete removal of ARGs/MGEs by composting was not achieved. Analysis of microbial communities revealed that changes in bacterial and fungal communities played a crucial role in the removal of ARGs/MGEs. The use of a compound microbial agent promoted composting temperature rise, which altered the microbial community structure and resulted in the removal of ARGs/MGEs.

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.
