Summary: Antimicrobial transformation products (ATPs) in the environment have become a significant concern due to their potential health risks. However, limited research has been conducted on ATPs, and the transformation pathways of most antimicrobials remain unclear. This study used a non-target screening strategy based on molecular networks to identify ATPs in pharmaceutical wastewater and discovered 52 antimicrobials and 49 transformation products. Among them, 30 transformation products were previously unreported in the environment. Based on recent European criteria, the persistence, mobility, and toxicity (PMT) assessment of the transformation products revealed that 47 of them were potential PMT substances. These findings emphasize the need for further research on novel ATPs. A non-target screening strategy combining molecular networks and in silico tools for structure annotation was proposed, which identified novel ATPs with similar PMT characteristics as their parent antimicrobials.

Summary: Dual-atom catalysts (DACs) show great potential in various catalytic reactions, but the origin of their high activity and the mechanism behind the enhancement are still not well understood. In this study, FeCo-N/C dual-atom catalyst was compared with its single-atom counterparts in activating peroxymonosulfate (PMS) for pollutant abatement. It was found that the spin-state reconstruction on FeCo-N/C effectively improves the electronic structure of Fe and Co, leading to enhanced PMS activation efficiency and a remarkable boost in the Fenton-like reaction. The study provides a mechanistic understanding of the enhanced catalytic activity of DACs and expands their potential applications.

Summary: Redox transformation is a useful strategy for reducing metal oxysalts toxicity and facilitating their removal from water. The synergistic effect in the redox transformation of coexisting oxyanions was evaluated using different processes, and the UV/AcAc process was found to be highly effective in oxidizing As(III) and reducing Cr(VI) without the need for additional treatment. This UV/AcAc process consumed significantly less electric energy compared to the sum of UV/H2O2 and UV/sulfite, making it a promising advanced oxidation and reduction process (AORP).

Summary: In this study, the evolving role of calcium ion (Ca2+) on phosphate removal by nanosized hydrated lanthanum oxides confined in cross-linked polystyrene beads was investigated. The presence of Ca2+ initially enhances the phosphate uptake by the adsorbent, but with ongoing cyclic runs, the role of Ca2+ becomes negative. The formed Ca-P precipitates accumulate on the surface of the nanoparticles and deplete the active adsorptive sites, leading to the formation of irreversible LaPO4 center dot xH(2)O under nanoconfinement.
