Summary: In this study, surface-enhanced Raman spectroscopy (SERS) combined with chemometric methods were used to analyze four benzimidazole (BMZs) residues in corn. Sulfhydryl functionalized Fe3O4@SiO2@Ag-SH magnetic SERS substrates were prepared for the spectral analysis and chemometric analysis was performed using the partial least squares regression discrimination analysis (PLS-DA) model. The results showed that this strategy could rapidly determine BMZs residues in food with high accuracy and no significant difference compared to HPLC.

Summary: A silver colloid SERS analysis method combined with a exhaustive peak-seeking method for the quantitative determination of thiram and ziram was introduced in this paper. By improving the preparation method of silver colloids, adding suitable activators and optimizing the detection process, a liquid detection system with good repeatability and a wide linear quantitation range was obtained. This analysis system effectively solves the problem of poor repeatability and a narrow linear quantification range in SERS analysis based on silver colloid substrates.

Summary: This study investigates the physicochemical and geochemical changes in soils surrounding a self-burning waste pile in an abandoned coal mine. The results indicate that coal mining can lead to the generation of organic and inorganic contaminants that can spread to surrounding soils. Multivariate statistics and geostatistical methodologies were used to analyze the statistical and spatial relations of different elements and infer their sources. The presence of 16 priority Polycyclic Aromatic Hydrocarbons (PAHs) in the soils suggests contributions from various sources.

Summary: Recovering biomolecules from food industry by-products is important for a circular economy strategy, but their contamination with mycotoxins limits their application range. This systematic review examines the contamination, distribution, and prevalence of mycotoxins in food by-products from 2000 to 2022. The evaluated by-products include distiller dried grain with solubles, brewer's spent grain, brewer's spent yeast, cocoa shell, grape pomace, and sugar beet pulp, which are frequently contaminated with AFB(1), OTA, FBs, DON, and ZEA mycotoxins.

Summary: The study focused on the tungsten Regoufe mine, which stopped operations in the 1970s. The research evaluated the contamination of soil, plants, and water in the mining area, specifically looking at potentially toxic elements (PTEs). The results showed that the area had a high level of contamination, posing ecological risks, particularly due to contributions from arsenic (As) and cadmium (Cd). However, it was difficult to establish a direct link between As contamination and mining activities, as the soils were already enriched in metals and metalloids from natural geological processes. The study also found that PTE levels in plants were lower than in soil, but bioaccumulation was influenced by site-specific soil concentrations of As and Pb. Magnetic studies indicated the presence of technogenic particles, likely formed during ore processing/mining activities. Overall, the levels of PTEs in surface and groundwater samples were relatively low, with the exception of As, which exceeded drinking water standards.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
