Summary: The study proposed a comprehensive method for characterizing compounds derived from Imperatae Rhizoma, utilizing different types of chromatographic separation techniques and establishing a feature-based molecular network for rapid classification and visualization of components. By combining UPCC-QTOF-MS and UPLC-QTOF-MS technologies, a total of 62 compounds were characterized, classified into six types, and five potential new compounds were detected. This approach facilitated the comprehensive chemical composition analysis of Imperatae Rhizoma and has the potential to improve the accuracy of herb quality evaluation for other herbs or preparations.

Summary: PFC concentrations were investigated in three major rivers in southern India, with perfluoro-n-hexanoic acid being the most detected congener. Higher levels of PFCs were observed in summer compared to post-monsoon season, mainly due to decreased river flow. Domestic and commercial wastewater were identified as the major sources, and most detected PFCs share a common migration source.

Summary: Using UPLC-QTOF/MS and plasma untargeted metabolomics analysis, this study revealed the changes in components and metabolic fluctuations of polygonatum under different processing times. The results showed that processed polygonatum exhibited changes in protein, fat, polysaccharide, flavonoids, saponins, and isoflavones. Additionally, four types of Lysophosphatidylcholines were found to be highly expressed in the plasma of rats in the SAD-9 group. Through network pharmacological analysis, it was determined that liquiritigenin and 4',5-dihydroxyflavone activated PLA2 type enzymes, promoting the production of lysophosphatidylcholine, and the SAD-9 processing method facilitated the effects of these two components.

Summary: In this study, needle-like SnO2/g-C3N4 nanocomposites were synthesized and showed efficient decomposition of tetracycline under visible light irradiation. The heterojunction between SnO2 nanoparticles and exfoliated g-C3N4 nanosheets promoted the separation of charge carriers, leading to enhanced degradation of tetracycline. This nanocomposite material has potential applications for the degradation of pharmaceuticals with similar chemical structures.

Summary: This study investigated the partitioning behavior of PFOA and PFOS in sediment samples from river systems. The results showed that the sediments had high sorption capacities for PFOA and PFOS, with the sorption increasing over time. Lower pH values and increasing ionic strength favored the sorption and partitioning of PFAS onto sediments in aqueous solution. This study provides important data and scientific knowledge for understanding the fate and sorption of PFAS in aquatic systems.

Summary: Pharmaceutical compounds (PCs) have become an important group of environmental contaminants globally, as their residues are constantly detected in the environment. This study aims to address the knowledge gap on the occurrence of selected PCs in environmental matrices in Africa compared to other regions, as well as their toxic effects on both aquatic and non-aquatic biota through ecotoxicity bioassays. Africa has the highest levels of certain pharmaceutical residues, while Europe has the lowest. However, there is limited data on the combined forms of pharmaceuticals for ecotoxicity bioassays.

Summary: Composite materials of graphitic carbon nitride (g-C3N4) doped with activated carbon (AC) were synthesized and applied for the degradation of enrofloxacin in an aqueous system. The composites showed enhanced photocatalytic performance and extended visible light response. The improved efficiency can be attributed to the increased surface area and high photoinduced charge separation. The composites also exhibited excellent recyclability and stability, making them promising candidates for environmental remediation.
