Summary: This study investigated the reservoirs and spread of antibiotic resistance genes (ARGs) in the Xilingol grassland system using high-throughput quantitative PCR and sequencing. A large number of different ARGs were observed in manure, soil, and water samples, with only 12 ARGs shared among all samples. The water environment was found to be a critical transmission source of ARGs in the grassland.

Summary: This study investigates the pattern of antibiotic resistance assembly and their unclear transfer in a soil-lettuce system. The research finds that the land application of treated erythromycin fermentation residue (EFR) poses risks due to the emergence of antibiotic resistance genes (ARGs) and potential exposure to humans. The study also highlights the role of erythromycin concentration in the evolution of endophytic ARGs.

Summary: The study found that mesophilic anaerobic digestion is more effective for treating tylosin fermentation dreg, especially when co-digesting with food waste. However, thermophilic anaerobic digestion has higher methane production rate and hydrolysis rate, but lower residual antibiotics. The addition of food waste can enhance methane production rate and yield under both temperature conditions.

Summary: The hydrothermal treatment is effective in destroying the lactam structure of penicillin, subsequently reducing the absolute copies of antibiotic resistance genes (ARGs) and the relative abundance of bacteria related to pathogens during composting. The bacterial community composition also changes during composting process, with a decrease in symbiotic or pathogenic bacteria and an increase in bacteria related to ureolysis and cellulolysis.

Summary: This study investigated the effects of different pretreatment approaches on the removal of antibiotic resistance genes (ARGs) during anaerobic fermentation of waste activated sludge. The results showed that pretreatments had significant impacts on the overall removal of ARGs, with Fe2+ activated persulfate (PS/Fe2+) having the highest removal efficiency. Mechanistic analysis revealed that pretreatments disrupted extracellular polymeric substances (EPS) and increased cell membrane permeability, leading to the release of ARGs and subsequent reduction of mobile genetic elements (MGEs) and extracellular ARGs. The study also found that pretreatments altered the microbial community structure and the abundances of potential ARGs hosts.

Summary: Leachate is a significant reservoir for antibiotic resistance genes (ARGs) and proper treatment is crucial for human health and ecosystem safety. In this study, high-throughput qPCR was used to investigate the removal of ARGs in full-scale leachate treatment plants (LTPs), revealing the importance of anaerobic digestion and membrane bioreactor processes. Integrated membrane filtration (UF-NF-RO) showed excellent removal efficiency of ARGs, reducing their absolute abundances by 3 to 6 orders of magnitude.

Summary: This study found that although the absolute abundance of ARGs decreased after treatment by drinking water treatment plants, there was a rebound of ARGs in the water distribution system, which should not be neglected. There was a significant correlation between microbial communities and ARG profiles, with the variation in ARG profiles primarily attributed to community composition.

Summary: Nearly 80% of the population in the Colombo district rely on the Kelani river for their major needs, but recent studies have shown contamination of groundwater and surface water with waterborne pathogens and antibiotics. The study identified nine antibiotic resistance genes, with high levels of penicillin and tetracycline resistance genes found in the lower part of the Kelani river basin. Regular monitoring and water quality management are essential to protect the drinking water quality in this area.

Summary: This study investigated the influence of penicillin V on antibiotic resistance genes (ARGs) in soil amended with hydrothermally treated penicillin V fermentation residue (PFR). The results showed that the residual penicillin V in soil could lead to the proliferation of soil ARGs, especially at higher concentrations. Horizontal gene transfer may contribute to the shift of ARGs in PFR-amended soil. Thus, it is important to remove residual penicillin V before applying PFR to soil.

Summary: This study investigated the association between ambient PM2.5, O3 pollution, and ovarian reserve in reproductive-aged Chinese women. The results showed that increased exposure to PM2.5 and O3 was associated with decreased AMH levels, indicating reduced ovarian reserve. Notably, the effects of O3 exposure on ovarian reserve were different from those of PM2.5 exposure.

Summary: Systemic insecticides and rising temperatures have combined effects on the abundance of Odonata nymphs in paddy fields. The standalone effect of insecticide exposure decreased the Odonata community, while nymphs decreased synergistically with temperature rise in paddy water. However, the impacts of each stressor alone varied among species.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

Summary: This study investigates the impact of biochar on methylmercury (MeHg) accumulation in rice. The results show that biochar reduces MeHg levels in paddy soils by decreasing bioavailable Hg and microbial Hg methylation. Additionally, biochar decreases the uptake and translocation of MeHg in rice plants, resulting in a reduction of MeHg accumulation in rice grains.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
