Summary: This study reconstructed the temporal trends of both legacy and novel BFRs in sediment cores along the Rhone River. It was found that while legacy BFRs peaked in concentration from the mid-1970s to the mid-2000s and stabilized by the mid-2010s, novel BFRs had concentrations two to four orders of magnitude lower and showed no decrease in recent years. Understanding the sources, contamination load, repartition in the environment, and toxicity of novel BFRs is necessary before their concentrations reach hazardous levels.

Summary: Surface soil and river sediment samples were collected from the downstream of Chuhe River basin in East China to investigate the occurrence and accumulation characteristics of legacy and novel brominated flame retardants (NBFRs). The concentrations of BDE-209 and nine NBFRs ranged from n.d. to 41.4 ng/g dw and from 0.29 to 19.73 ng/g dw in the collected samples. BTBPE was the predominant NBFR in both soil and sediment samples. The calculated concentration ratios of the total of the nine NBFRs to BDE-209 in most of the analyzed samples exceeded 1, indicating a clear shift from legacy brominated flame retardants to NBFRs in the downstream of Chuhe River basin.

Summary: This study analyzed sediment from Cienfuegos Bay, Cuba to examine the occurrence of organic pollutants from 1990 to 2015. The results showed the presence of regulated contaminants such as PCBs, OCPs, and PBDEs, with a decline in PCB contamination since 2007. Emerging contaminants, including PAEs, OPEs, and aHFRs, showed sharp increases, possibly due to the growing global usage of flame retardants and plasticizer additives. Local sources, such as a plastic recycling plant and urban waste outfalls, may contribute to these trends. Further research is needed to understand the influx of these emerging contaminants.

Summary: Brominated flame-retardants (BFRs) are environmental endocrine disruptors that potentially affect the endocrine system and cause dysfunction and disease. Widespread BFR exposure may cause multisystem toxicity, including cardiovascular toxicity in some individuals. BFRs not only increase heart rate, induce arrhythmia and cardiac hypertrophy, but also cause glycolipid metabolism disorders, vascular endothelial dysfunction, and inflammatory responses, all of which potentially induce pre pathological changes in atherosclerosis.

Summary: This study investigated the emission patterns of Cl/Br-PAHs in three typical industrial parks by analyzing surface soils. The results showed that Cl-PAHs were generally found in lower concentrations compared to Br-PAHs, with the highest Br-PAH concentration observed in the BFR manufacturing park. The levels of these chemicals in the parks were generally higher than their surroundings, except for the electronic waste dismantling park. The analysis of the composition of Cl/Br-PAHs suggested different sources for different industrial parks.

Summary: Seafood consumption is more frequent among Asians compared to other ethnic groups in the U.S., but there is little information about how culturally specific fish consumption contributes to exposure to toxicants. This study surveyed fish consumption among Chinese, Korean, and Vietnamese communities in Chicago and analyzed 103 seafood samples for mercury and organic chemicals. The research found that certain types of fish, such as bluefish, pike, and tuna steak, had high mercury levels, while octopus, shrimp, and tilapia were the least contaminated. Omega-3 fatty acids were more associated with organic contaminants than mercury. Consumption limitations were identified for seven types of fish based on risk assessment.

Summary: The protective effect of ethylcellulose microparticles loaded with olive mill pomace (OMP) as an alternative to synthetic antioxidants against oxidation of olive oils was evaluated. OMP extract was obtained using a solid-liquid extraction technique and encapsulated using a double emulsion solvent evaporation method. Fortification of olive oils with microparticles delayed peroxide formation, reduced content of secondary oxidation products, and slowed down hydrolysis processes. The results suggest that encapsulated extracts rich in antioxidants can be used as an alternative to synthetic antioxidants to enhance oil oxidative stability.

Summary: The study combines transcriptome and proteome analysis to investigate the global gene expression patterns associated with five prototypical CFTR mutations in Cystic Fibrosis (CF) patients. Differentially expressed genes and proteins reveal common and mutation-specific changes, highlighting functional signatures that are more associated with the specific molecular defects of each mutation rather than the CFTR loss-of-function phenotype. The analysis of translated-transcripts detected specifically in each mutation provides valuable insights into the pathophysiology of CF and may contribute to the identification of new therapeutic targets and biomarkers for CF.

Summary: This study evaluates the sustainability of using vineyard pruning waste extracts as natural additives for biodiesel production, comparing them with butylated hydroxytoluene. The oxidative stability of biodiesel and biodiesel-diesel blends is a major concern in the biofuel industry. Synthetic antioxidants are currently used to ensure oxidative stability, but natural alternatives from vineyard pruning waste extracts are explored in this work. The extract exhibits comparable antioxidant activity to the commercial antioxidant BHT. The environmental impacts of using these natural extracts in the production process are also assessed for the first time.

Summary: A systematic synthetic study was conducted to explain the common trend of selectivity towards multi-coupling over mono-coupling in Suzuki-Miyaura reactions. This preference was observed under various reaction conditions, including different halobenzenes, substituents on the boronic acid, and changes in catalyst and temperature. Additionally, it was found that the reaction selectivity increased for more reactive systems and more diluted media. The results provide experimental evidence that the formation of totally substituted coupling product is kinetically favored by the proximity of the regenerated catalyst and the newly formed coupling intermediate.

Summary: The wetting behavior of ionic liquids (ILs) on different surfaces was studied by depositing ILs films using thermal evaporation. The deposition rate and substrate temperature were found to significantly affect the droplet coalescence and morphology. The results showed that an increase in the deposition rate and/or substrate temperature intensified the droplet coalescence on ITO surfaces, while the effect was smaller on the Ag surface due to strong adhesion. Moreover, modifying the deposition parameters resulted in different droplet morphologies for different ILs.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.
