Summary: This study focused on the simultaneous photocatalytic degradation of different parabens and UV filters using a novel double plasmonic nanophotocatalyst. The nanophotocatalyst showed superior activity compared to individual nanoparticles due to the presence of two simultaneous surface plasmon resonances and a hetero-junction structure. Superoxide radicals were identified as the key reactive species. The degradation process was further investigated and optimized in different water matrices.

Summary: The detection and understanding of emerging contaminants (ECs) pose new challenges to water pollution control. Triclosan (TCS), an emerging contaminant widely found in the environment, is a commonly used antibacterial agent. Microdialysis (MD), a sampling technique, combined with UHPLC-QTOF/MS analysis, was used to identify endogenous metabolites as biomarkers of TCS exposure in living crucian carp. The quantification of these biomarkers using UHPLC-MS/MS provided continuous monitoring of the effect of TCS on endogenous metabolites, contributing to a better understanding of its toxicological effect.

Summary: Passive sampling combined with thermal desorption gas chromatography-mass spectrometry (TD-GC-MS) was used to monitor emerging organic contaminants (EOCs) and solvents in indoor environments of both conventional and vocational training schools. Experimental diffusive uptake rates of target compounds were determined successfully, and concentrations of EOCs and solvents were found to be higher in the vocational training school compared to the conventional school. Cleaning products (conventional school) and classroom activities (vocational training school) were identified as the main sources of EOCs and solvents.

Summary: This study focuses on the implementation of a gas chromatograph-photoionization detection (GC-PID) analyzer for the continuous monitoring of 1,3-butadiene (1,3-BD) levels in urban and industrial atmospheres. The study found that the concentrations of 1,3-BD recorded by the GC-PID analyzer were comparable to those obtained by active sampling, and the concentration peaks showed consistency in values and time slots. In the test of urban atmospheres, the results showed that the concentrations of 1,3-BD were related to prevailing wind direction and activities in the petrochemical zone, while other factors had minor effects on the distribution of this pollutant.

Summary: In this study, an ionic covalent organic framework (iCOF) surface grafting monolithic sorbent was prepared for in-tube solid-phase microextraction (SPME) of aristolochic acids (AAs) in various samples. The density of quaternary ammonium ions in the iCOF was modulated for enhanced adsorption of AAs. The iCOF surface grafting monolithic sorbent was confirmed by different means. Several operating conditions were optimized to develop the online in-tube SPME-HPLC method, which showed good linearity, low limits of detection, and high recoveries for AAs in serum samples. This study presents a feasible approach for the application of COF-based monolithic sorbents in sample preparation.
