Summary: C and O dual-doped g-C3N4 photocatalyst was used to activate peroxydisulfate and effectively disinfect tetracycline-resistant Escherichia coli. The study also found that the photocatalyst could degrade antibiotic resistance genes by generating more free radicals and causing oxidative stress in cells. This research provides valuable insights into the inactivation of antibiotic resistant bacteria and offers a potential strategy for preventing the dissemination of antibiotic resistance genes in water contamination.

Summary: In this study, a novel UV-LED-driven heterogeneous chlorine activation system was constructed by modifying the metal-organic framework NH2-MIL53(Fe) with organic ligands containing sulfur functional groups. This system demonstrated improved efficiency and reduced generation of disinfection by-products compared to traditional UV/chlorine processes. The introduction of sulfur functional groups facilitated the excitation of electrons and effective separation of photoholes and photoelectrons, leading to enhanced removal of target pollutants.

Summary: The literature on microplastics in biological tissues has increased in recent years. This review synthesizes evidence on the preparation of biological tissues, chemical identification of microplastics, and their accumulation in tissues. Issues such as unclear criteria for selecting extraction methods and inconsistent analytical methodologies for chemical identification have been identified. The sizes of microplastics found in biological tissues may be biologically implausible, and further assessment is needed to determine their true presence.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: A comprehensive study was conducted to investigate the efficient removal of human body fluids (HBFs) related pollutants from swimming pool water using UV irradiation combined with electrochemistry. The results showed that the EC/UV treatment exhibited the highest removal rates for these pollutants compared to other treatments. The EC/UV process was resilient to changes in water parameters and could lessen the generation of disinfection by-products. This green technology has the advantages of no chlorine-based chemical additive, easy operation, continuous disinfection efficiency, and fewer byproducts production.

Summary: This study reveals that environmentally persistent free radicals (EPFRs) formed on photoaged disposable plastic cup microplastics (DPC-MPs) cause toxicity in nematodes, and oxidative stress plays a significant role in regulating this toxicity.

Summary: This study prepared nano-cerium based adsorbents with different surface defects and Ce(III) content to investigate their effects on the Cr(VI) adsorption capacity. The results showed that the optimized adsorbent performed well over a wide pH range and the performance was closely related to the contents of Ce(III) and surface defects.

Summary: The interaction process between polyaluminum-titanium chloride composite coagulant (PATC) and aged polystyrene powder (APSp) was studied. The rise of O-containing functional groups in APSp increased the formation of C-O-M coordination bonds and hydrogen bonds, improving the removal of PSp. Al13(OH)53Ti13O17(H2O)20 electrostatic attraction brought Al13Ti13 close to APSp, followed by hydrogen bonding and complexation. However, the Al13Ti13-APSp complexes were easily converted to monomers and dimers during coagulation, affecting the coagulation efficiency.

Summary: This study presents a proof of concept for a technology that integrates PET recovery from mixed plastic waste and plastic pyrolysis. By depolymerizing PET into TPA using a low volatility oil as medium, it achieves low-pressure operation and a selective separation and recovery of TPA from the product mix. Full PET conversion and high TPA recovery were achieved, making it an effective solution for processing mixed waste streams and improving the yield and quality of liquid product from thermal pyrolysis compared to untreated feedstock.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: This study utilized Mo powder and STPP to enhance the performance of the sodium percarbonate system in pollutant degradation. The presence of Mo and STPP resulted in a higher degradation rate of the model pollutant SMX, with low oxidant consumption. The system generated multiple active species through a series of chain reactions at different pH values, exhibiting excellent performance towards electron-rich pollutants. Furthermore, Mo demonstrated excellent stability and reusability.

Summary: Geopolymer solidification/stabilization technology has developed rapidly in the remediation field of heavy metal-contaminated soil. However, there is a low anionic heavy metal immobilization efficiency in geopolymers. This study achieved the solidification/stabilization of cations and anions in antimony mine soils using a one-part blast furnace slag-based geopolymer system with the addition of landfill leachate concentrate (LLC). The LLC addition significantly improved the fixation rates of Sb and As, reducing the leaching concentration of all heavy metal ions to ppb level.

Summary: Heavy metals and disinfectants can affect the spread of antibiotic resistance genes in soil microbes. The stability and availability of these substances, as well as the pH of the soil, play a role in the resistance profiles in soil. This study found that the simultaneous addition of arsenic and triclocarban increased the abundance of antibiotic resistance genes at pH > 6 due to co-selective pressures. Arsenic and triclocarban also influenced the spread of mobile genetic elements affecting the soil resistome. Additionally, pH altered the patterns of microbial inhabitants and impacted the prevalence of certain antibiotic resistance genes.

Summary: This study successfully applied the C7 consortium extracted from sewage sludge to accelerate the degradation of IBP, both in solution and adsorbed in sludge. The C7 consortium enriched specific bacterial species, with S. wittichii likely being the key player in IBP mineralization. Furthermore, several bacterial strains that were not previously described as IBP degraders were isolated and identified.
