Summary: Honeydew honey, known for its higher antibacterial and antioxidant properties, can be differentiated from blossom honeys based on electrical conductivity. However, criteria for distinguishing between different types of honeydew honeys, such as spruce, fir, and pine, were not established. By analyzing the electrical conductivity, phenolic, and sugar profiles, markers like protocatechuic acid, oligosaccharides, and specific sugar compounds were identified for the classification of authentic coniferous honeydew honeys. Further analysis of carbohydrates using high-performance liquid chromatography allowed for a correct classification of 96.75% of the honey samples based on sugar marker compounds.

Summary: The only known natural samples of high-pressure mantle constituents are mineral inclusions in diamonds, and their origin and formation have been a subject of debate. By analyzing trace elements in olivine crystals from South Africa, researchers have found evidence suggesting that these crystals formed in the deep upper mantle and potentially in the mantle transition zone. These findings provide insights into Earth's early mantle evolution and the formation of ancient continental and oceanic crust.

Summary: The geographic origin of salt is considered unimportant for its quality, but certain brands, especially sea salt, are sold at higher prices. Therefore, it is necessary to control the declared geographic origin of salt. Delta S-34 analysis and element concentration analysis were conducted. The results showed similar values for sea salt samples, while slight differences were found in Mediterranean salt samples. Rock salt samples showed varying values depending on formation time and origin. Terrestrial salt samples differed significantly from marine ones in elemental patterns, and differences within marine samples exist as well.

Summary: The quality of iron ores has a significant impact on the formation of harmful pollutants during the steel-making process. This study investigated the effect of different properties of iron ores on the formation of dioxins during sintering. The results showed that the concentration of iron in the ores was positively correlated with PCB 114 formation, while concentrations of aluminum, titanium, and chlorine greatly increased PCDD/F and PCB emissions. Sulfur levels and density were also related to increased emissions, while silicon concentrations played a role in reducing emissions. The study also identified the optimal size range of iron ores to reduce dioxin emissions without affecting product quality.

Summary: Despite concerns about indoor dust exposure risks from trace metals, limited research has been conducted on their sources and their relationship to outdoor soils. This study investigated the concentrations and sources of trace metals (As, Cr, Cu, Mn, Pb, and Zn) in home-matched indoor dust, garden soil, and road dust samples in Sydney, Australia. The results showed that all trace metals were more elevated indoors than in their corresponding garden soil samples, indicating that indoor sources were more relevant for Cu and Zn, while Pb remained an important source for indoor contamination through garden soil. The study also identified common sources of trace metals in road dust, garden soil, and indoor dust. Furthermore, the study revealed that a significant portion of indoor dust particles originated from outdoor sources, and the isotopic compositions of Pb in soil and indoor dust were moderately correlated, confirming the influence of outdoor contaminants on indoor environments.

Summary: Aeration of water contaminated with PFASs can effectively separate and concentrate PFAS through adsorptive bubble fractionation. This study investigated the impact of changes in environmental and process parameters on PFAS removal efficiency and found that bubble fractionation can achieve high levels of overall PFAS removal (>95%) across a wide range of saline and temperature conditions. The removal of certain short-chain PFAS species was improved by increased electrolyte concentration and decreased temperature. However, higher temperature slightly reduced the total PFAS removal rate (to 93%). These findings demonstrate the viability of bubble fractionation as a primary step for PFAS removal in contaminated water.

Summary: Adsorptive bubble separation techniques, such as foam fractionation, are being used to extract per- and polyfluoroalkyl substances (PFAS) from water. However, there is a lack of mathematical models for their removal. This study presents a theoretical framework for the kinetics of PFAS removal using a semi-batch foam fractionation process, considering factors such as adsorption, entrainment, and volatilization. The proposed models provide quantitative tools for process design and optimization of PFAS removal.

Summary: This study investigated the concentrations of PCDDs, PCDFs, and dl-PCBs in sintered products and emitted dust samples. The results showed higher concentrations of PCDDs than PCDFs in sinter, but three out of four test experiments showed higher concentrations of PCDFs than PCDDs in dust samples. The PCB analysis showed that non-ortho PCBs had higher concentrations than mono-ortho PCBs in both solid samples. The study also found differences in PCDD/F profiles and correlation matrix between sinter and dust samples, suggesting different mechanisms of dioxin formation during sintering.
