Summary: Nowadays, the growing popularity of e-cigarettes among non-smokers and teenagers has become a pressing public health issue. Therefore, developing methods to monitor toxic compounds in their smoke is a profitable goal. In this study, two coordination polymers (CPs) with nanorod and microsphere morphologies were proposed as extractive phases in a needle trap device (NTD). The nanorods exhibited higher extraction and desorption efficiency for polyaromatic hydrocarbons (PAHs). The nanorod CP was further used to develop an NTD-GC-MS method for quantification of PAHs in cigarettes and e-cigarette smoke, showing reliable performance with acceptable linearity, low limits of detection, suitable relative standard deviations, and long lifespan.

Summary: Polybutylene succinate/modified cellulose bio-nanocomposites were synthesized and used as sorbents for needle trap microextraction of polycyclic aromatic hydrocarbons. The modified cellulose nanocrystals improved the dispersion of nanoparticles in the matrix and enhanced the surface area and stabilities. The extraction parameters were optimized, resulting in a method with low detection limits, good repeatability and reproducibility, and a wide linear range. The developed method showed high enrichment factors and relative recovery values in real water samples.

Summary: In this study, polydisperse phenanthrene microparticles were prepared with spherical morphology, with the autofluorescence aiding in the analysis of impact craters. Coating the microparticles with a polypyrrole overlayer reduced autofluorescence, showing potential for evaluating thermal ablation. The core-shell microparticles fired into aerogel targets retained intact polypyrrole overlayer, suggesting their usefulness as model projectiles for assessing thermal processing in experiments related to capturing intact PAH-based dust grains in space missions.

Summary: PAH pollution and antibiotic pollution are common environmental problems in the Yellow River Estuary, China. This study investigated the bioaccumulation and influencing factors of PAHs and antibiotics in aquaculture areas of the Yellow River Estuary. The study found that 3-ring PAHs and fluoroquinolones were dominant contaminants in the area. The concentrations of PAHs and antibiotics in lipid-rich tissues were higher than that in muscle, indicating that lipid content is an important factor affecting bioaccumulation.

Summary: Cholestasis is a clinical complication that affects the liver, but other organs, including the lungs, can also be impacted. Cholestasis-induced lung injury can lead to severe complications such as respiratory distress, pulmonary infections, and tissue fibrosis. This study investigated the role of carnosine in protecting against cholestasis-induced lung injury. It was found that carnosine significantly reduced oxidative stress, inflammation, tissue fibrosis, and histopathological changes in the lungs of cholestatic animals.

Summary: Vacuum-assisted headspace extraction (VA-HSE) is an efficient method for extracting volatile and semi-volatile species. This research focused on modeling VA-HSE of solid samples by considering the impact of reduced pressure on the movement of analyte molecules. The proposed model divided the sampling space into different areas and included a comprehensive equation. The results showed that vacuum increased the volatility of analytes in solid samples and facilitated the diffusion of analyte molecules into the cavities within the solid material. The experimental data validated the reliability and practical relevance of the model.

Summary: PFAS are a group of fluorocarbon compounds with wide-ranging applications, but their persistence and toxic properties make them a concern in the environment. Their strong C-F bonds make it difficult for chemical or biological mechanisms to break them down. Therefore, sensitive and selective analytical methods are needed to detect and trace PFAS in biological and environmental matrices.
