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.

A systematic review of methods for the analysis of total per- and polyfluoroalkyl substances (PFAS)

The Science of The Total Environment, Journal Year: 2025, Volume and Issue: 967, P. 178644 - 178644

Published: Feb. 12, 2025

This manuscript systematically reviews 156 peer-reviewed articles on methods for estimating total per- and polyfluoroalkyl substances (PFAS), following preferred reporting items systematic meta-analyses (PRISMA) guidelines. Direct indirect of PFAS include targeted analysis, fluorine (TF), organic (TOF), extractable (EOF), absorbable (AOF), oxidizable precursor (TOP) assay. Combustion ion chromatography (CIC) was the most utilized method (>50%), followed by particle-induced gamma-ray emission (PIGE, 9%) high-resolution-continuum source graphite furnace molecular absorption spectrometry (HR-CS-GFMAS, 6%). Techniques like instrumental neutron activation analysis (INAA) nuclear magnetic resonance (NMR) were less common. A geographic bias evident, with 69% studies from US (33%), Sweden (12%), China Germany (11%). Most research environmental samples (water, soil, sediments), while significant data gaps noted in South America, Africa, atmospheric PFAS. Challenges inter-laboratory comparisons arise inconsistent units (e.g., mg/L, μg/m3, %, etc.). About 75% involved pre-treatment solvent extraction, sorbents), 25% did not. detection limit observed concentrations varied widely, low water (ng/L) to higher levels biota, products (mg/L). Limitations contradictory results when complementary techniques are applied same sample, potentially leading over- or under-estimation. Across studies, a substantial fraction TF remains unaccounted for, highlighting need non-targeted screening (NTS) identify unknown (UPFAS UOPFAS). Bridging these is critical advancing risk assessment.

New Insights into Thermal Degradation Products of Long-Chain Per- and Polyfluoroalkyl Substances (PFAS) and Their Mineralization Enhancement Using Additives

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 3, 2024

The products of incomplete destruction (PIDs) per- and polyfluoroalkyl substances (PFAS) represent a substantial ambiguity when employing thermal treatments to remediate PFAS-contaminated materials. In this study, we present new information on PIDs produced in both inert oxidative environments from five long-chain PFAS, including three now regulated under the U.S. Safe Drinking Water Act, one cationic precursor compound, C10 PFAS. data did not support generation tetrafluoromethane any studied carbonyl fluoride was found only potassium perfluorooctanesulfonate (K-PFOS) heated air narrow temperature range. Oxidative conditions (air) were observed facilitate PFAS degradation accelerate mineralization K-PFOS. Spectroscopic suggest that is initiated by cleavage bonds form perfluoroalkyl radicals, leading organofluorine (e.g., perfluoroalkenes). air, radicals react with oxygen oxygen-containing PIDs. enhanced adding solid additives, which categorized as highly effective granular activated carbon (GAC) certain noble metals), moderately effective, noneffective. Remarkably, simply GAC, achieved >90% perfluorooctanoic acid at 300 °C ∼1.9 atm within just 60 min without using water or solvents.
