As food packaging materials are in direct contact with the we eat and cook under heat or pressure, consumers apprehensive of their adverse effects on products. Perfluoroalkyl polyfluoroalkyl substances (PFASs) often used because hydrophobic properties; however, some PFASs carcinogens, thus prompting further studies effects. In this study, a pretreatment method 31 coffee was established using QuEChERS extraction analyzed by liquid chromatography-tandem mass spectrometry. We brewed 32 types capsule distributed Korea, them for PFASs, evaluated safety. The results show that perfluorooctanoic acid 8:2 fluorotelomer sulfonate levels higher machine-brewed than coffees manually through paper filter. However, hazard quotient excess cancer risk all samples lower World Health Organization standards, therefore, these considered safe. study may aid expanding existing literature PFAS detection relation to human health.

In this study, dissipative particle dynamics (DPD) simulations were employed to determine the critical micelle concentration (CMC) of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in ionic aqueous solutions. This approach provides precise CMC data for PFAS surfactants presence various species, thereby addressing a gap current literature. Additionally, study contributes development open-source molecular force fields charged perfluorinated compounds, which are currently limited. These models incorporate hydration free energy values obtained from density functional theory (DFT) account interactions through well-established linear relationship. Hydrophobic between surfactant tail water fine-tuned match chosen surfactants. Then, DPD successfully predicted diverse range surfactants, including those based on hydrocarbons PFAS, demonstrating ability represent realistic salinities encountered natural waters. Experimental validation methodology was conducted using sodium n-nonyl sulfate (SNS) n-dodecyl (SDS) via interfacial tension measurements, confirming accurate representation changes with salinity. enhances our understanding behavior solutions valuable tool predicting complex environmental systems.
