Summary: The electrochemical-assisted ultraviolet light coupled peroxodisulfate system (E-UV-PDS) was used to degrade ciprofloxacin (CIP). The study found that electrolysis and ultraviolet photolysis had synergistic effects, and explored the effects of initial pH, voltage, peroxodisulfate dosage, CIP concentration, and coexisting anions on the degradation process. The results showed that CIP could be efficiently degraded under certain conditions, and intermediate products were identified and degradation pathways were speculated using LCMS.

Summary: Ordered mesoporous carbon materials (OMC-Co-Tx) functionalized with catalytically-active metals were synthesized through evaporation-induced self-assembly and calcination at (600 to 800) degrees C. These materials were then used as activators for peroxymonosulfate (PMS) to remove sulfamethoxazole (SMX) from aqueous solutions. The increase of calcination temperature improved the catalyst behavior, resulting in better SMX degradation.

Summary: CoFe2O4 magnetic nanoparticles were used as heterogeneous catalysts to activate PMS for efficient removal of MOX. The degradation of MOX followed a pseudo-first order kinetic reaction equation, with SO4•- playing a dominant role in the degradation process. Five probable degradation pathways of MOX were proposed based on identified intermediates, and the presence of certain ions had negative effects on MOX removal efficiency.

Summary: In this study, the role of singlet oxygen (1O2) in the removal of organic compounds was evaluated. The results showed that surface-bound SO4·- was the dominant species, and the quenching effect of FFA was not solid evidence to identify 1O2. It was also found that the selective removal of some organics was due to the good ability of corresponding inorganic radicals (Cl·, NO3·, HCO3·, or HPO4·) to degrade these organics, rather than 1O2 as the key reactive oxygen species.

Summary: This study utilizes piezocatalysis to enhance redox reactions in heterogeneous peroxymonosulfate activation, leading to improved pollutant degradation. The results suggest that sulfate radical and singlet oxygen are the primary reactive oxygen species. Additionally, the presence of dissolved oxygen significantly enhances the efficiency and activity of peroxymonosulfate, resulting in more effective pollutant degradation.

Summary: The brownmillerite-type oxide Ca2Co2O5 (CCO) was synthesized and used for the first time to degrade organic pollutants with peroxymonosulfate (PMS) as oxidant. It showed higher activity and stability compared to other Co-based catalysts, degrading over 93% of acid orange 7 in 7.5 minutes under mild conditions. The catalyst's performance was attributed to the easy oxidation of Co(II) species, strong interactions between CCO, PMS, and pollutants, and the synergistic effect between Co and Ca. Additionally, a new mechanism involving radicals produced from low valent Co species oxidation and direct electron transfer process through high valent Co species was identified, providing insights into PMS-mediated reaction.

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: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

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.

Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
