Summary: This study investigated the levels of PCDD/Fs and dl-PCBs in the serum of residents in two urban-industrial zones near and far from an energy recovery plant in Gipuzkoa, Spain. Serum samples were collected from 227 participants and analyzed to determine the concentrations of these compounds. The study found that age, sex, lifestyle factors, and diet were associated with the variability of the measured compounds in the participants' serum.

Summary: The aim of this study was to understand the formation of volatile organic compounds (VOCs) caused by thermal processing by tracking changes in the volatilome of cold-pressed oil and press cakes obtained from roasted seeds. The study found that seed roasting increased the formation of Maillard reaction products and the levels of aldehydes, ketones, and sulfur-containing compounds. It also revealed changes in non-volatile metabolites of oil and press cake. These findings provide valuable insights into rapeseed processing in cold-pressed oil production.

Summary: This study investigated the atmospheric concentrations and sources of PCBs, PCNs, and PCDD/Fs in a steppe in North China. The results showed that wood and coal combustion were the main sources of PCBs and PCNs, while highly chlorinated homologs dominated the PCDD/Fs. Legacy capacitor impregnating agents and transformer oils also significantly contributed to the pollution of PCBs and PCNs. Long-range transport was not the main source of persistent organic pollutants in the ranch atmosphere.

Summary: GC x GC-TOFMS was used to analyze the molecular compositions of hydrocarbons in tars produced from slow pyrolysis of a low-maturity lignite, with significantly more hydrocarbons identified in the lignite pyrolysis tar compared to the EL-tar. The study revealed that pyrolysis of lignite at 500 degrees C released a variety of biomarker hydrocarbons, including open-chain and cyclic aliphatic hydrocarbons. Additionally, GC x GC-TOFMS was able to distinguish between different isomers of terpenoid hydrocarbons and various homologues of cyclopentane/cyclopentene and cyclohexane/cyclohexene.

Summary: Biosorption using phosphorylated hazelnut shell waste (FHS) is a promising method for lithium removal and recovery. This study investigated the performance of a continuous-flow packed-bed column system using FHS for ultra-low level lithium removal. The results showed that the lihium biosorption capacity of the FHS column was unaffected by the bed height, but decreased with increasing flow rate.

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.

Summary: A chitosan-alginate sponge with multiple cross-linking networks was developed for adsorption and enrichment of anionic dyes from food samples. The sponge showed better three-dimensional network structure, mechanical behavior, and stability compared to pure chitosan and alginate sponges. The adsorption performance and selectivity of the sponge were systematically studied, and it maintained high adsorption capacity and selectivity for anionic dyes. The sponge also showed satisfactory reusability and was successfully combined with high-performance liquid chromatography for the enrichment and detection of anionic dyes in candy and cocktail samples.

Summary: Analysis of in vivo exposure to traditional Chinese medicine using mass spectrometry is helpful for identifying effective ingredients and developing new drugs. This study focused on Forsythia suspensa (Lian Qiao) and used metabolomics technology to explore its in vivo exposure. By comparing the differences before and after administration, a complete set of nontargeted analysis strategies for TCM exposure was established. The study identified 393 Lian Qiao-related chemical components in mice after administration, including prototypes and metabolites. This study provides a reference for research on the active ingredients of Lian Qiao in vivo.
