PFAS contamination is a global issue, affecting various food sources, especially animal-based products like eggs and dairy. Collect scientific evidence of the presence in diverse edible resources along with related risks to human health, pursuing following objectives: determination level terrestrial chain contamination; health risk. Scopus, PubMed, Web Science databases. 4952 papers published from January 2013 August 2024 were retrieved at end selection process, 40 studies included. Clear description methodology used for detection; relevance or species, their parts, intended consumption; assessment Higher number China, 17, Italy 6 studies. The most detected PFOA PFOS. PFOS was maximum concentration about ng/g 2.5 ng/g, muscles cow pork, respectively. Among animal products, contaminated higher than 100 ng/g.

Abstract Per- and polyfluoroalkyl substances (PFAS), previously known as perfluorinated compounds (PFC), are a group of synthetic chemicals widely used over the past decades. Their extensive application, combined with their environmental persistence, has contributed to ubiquitous presence in environment associated toxicological risks. Regarding humans, blood serum testing remains primary method for biomonitoring PFAS exposure, while breast milk also been due transfer these from mothers infants during lactation. This paper aims review scientific literature (using PubMed Scopus databases) on concentrations non-occupationally exposed women. Where available, estimated daily intake by breastfeeding is examined. The reviewed studies categorized continent country/region, revealing significant lack data many countries, including both developed developing nations. findings indicate substantial variability concentrations, influenced factors such geographic location, sampling year, specific analyzed. Among identified compounds, perfluorooctane sulfonate (PFOS) perfluorooctanoic acid (PFOA) most commonly detected, along perfluorohexanesulfonic (PFHxS) perfluorononanoic (PFNA), being only regulated maximum levels certain foodstuffs. Most were conducted before implementation current (updated) tolerable weekly (TWI) values substances. Consequently, majority reported low health risk infants, even high-intake scenarios. Nevertheless, urgently needed countries limited or no data, new investigations should assess whether intakes exceed updated TWI. Special focus be given rural industrial areas where exposure remain poorly understood.

Nano-/microrobots have been demonstrated as an efficient solution for environmental remediation. Their strength lies in their propulsion abilities that allow active “on-the-fly” operation, such pollutant detection, capture, transport, degradation, and disruption. Another advantage is versatility, which allows the engineering of highly functional solutions a specific application. However, latter can bring complexity to applications; versatility dimensionality, morphology, materials, surface decorations, other modifications has crucial effect on resulting abilities, compatibility with environment, overall functionality. Synergy between decorations its projection functionality object nanoarchitectonics. Here, we scrutinize nano-/microrobots eyes nanoarchitectonics: list general concepts help assess synergy limitations individual procedures fabrication processes operation at macroscale. The nanoarchitectonics approached from microscopic level, focusing dimensionality through nanoscopic evaluating influence decoration nanoparticles quantum dots, moving molecular single-atomic level very fine tuning presented review aims lay provide overview advanced nano-/microrobot remediation beyond.

Deep eutectic solvents (DESs) are recognized as sustainable mediums, and DES-related materials have been used for the detection of perfluoroalkyl substances (PFASs). However, such studies were usually limited to only one category PFASs among massive target compounds. Additionally, selectivity related method still needs improvement. In this study, a convenient effective direct selective microextraction multiple was developed based on target-specific DES-based superparamagnetic nanofluid. Parameters DES compositions, amount nanofluid, time systematically investigated establish straightforward, rapid, sensitive, efficient green pretreatment method. Under optimal conditions, demonstrated high sensitivity, good precision, limit 0.04–8.71 ng kg−1, spike recovery 80.49–119.95%, low matrix effects (<20%). The potential mechanism elucidated by ab initio molecular dynamics (AIMD) simulations. solvent system exhibited diverse interaction modes with analytes varying types, including hydrogen bond acceptors (HBA)···PFASs, HBA···FAAs···hydrogen donors (HBD), hetero-halogen interactions. Finally, applied monitoring 13 compounds in 17 edible oil samples, targets detected range 0.05–10.04 kg−1.
