Molecules, Journal Year: 2025, Volume and Issue: 30(5), P. 994 - 994

Published: Feb. 21, 2025

Per- and polyfluoroalkyl substances (PFASs) have been widely used in the production of consumer products globally due to excellent water oil resistance anti-fouling properties. The multiple toxic effects some PFASs also pose a threat human health ecosystem, frequent use certain increased risk exposure PFASs. More data on occurrence, concentration, migration is urgently needed address possible risks posed by products. This paper reviews PFAS concentrations found, characteristics known, arising from several types over last five years. considered here include food contact materials, textiles, disposable personal hygiene influence different factors process these are summarized discussed. Additionally, main approaches models assessment evaluated summarized. Current challenges future research prospects this field discussed with view providing guidance for regulation

Per- and polyfluoroalkyl substances (PFAS) in breast milk and infant formula: A global issue

Environmental Research, Journal Year: 2022, Volume and Issue: 219, P. 115042 - 115042

Published: Dec. 16, 2022

Per- and polyfluoroalkyl substances (PFAS) are transferred from mother to infants through breastfeeding, a time when children may be particularly vulnerable PFAS-mediated adverse health effects. Infants can also exposed PFAS infant formula consumption. Our recent literature-based scoping of breast milk levels reported that four often exceeded the United States Agency for Toxic Substances Disease Registry (ATSDR) children's drinking water screening in both general population highly impacted communities U.S. Canada. This work presents comparison global measurements with only health-based values specific children. We focused on which ATSDR has developed values: PFOA (perfluorooctanoic acid), PFOS (perfluorooctanesulfonic PFHxS (perfluorohexanesulfonic PFNA (perfluorononanoic acid). Published literature were identified via PubMed searches. Data compared values. Breast concentrations exceed values, regardless geographic location. The limited information suggests its use does not necessarily result lower exposures, especially formulas reconstituted containing PFAS. Unfortunately, individuals generally cannot know whether their infant's exposures Thus, it is essential pregnant lactating women others, those having lived PFAS-contaminated communities, have data required make informed decisions nutrition. An international monitoring effort access affordable testing needed milk, fully understand exposures. Currently, our understanding demonstrable methods reducing emerging limited, making this research communications surrounding even more important.

Per- and polyfluoroalkyl substances (PFAS): Trends in mass spectrometric analysis for human biomonitoring and exposure patterns from recent global cohort studies

Environment International, Journal Year: 2024, Volume and Issue: 194, P. 109117 - 109117

Published: Nov. 7, 2024

Per- and polyfluoroalkyl substances (PFAS) are widespread environmental contaminants that have been shown to contribute human exposure, thereby raising a range of health concerns. In this context, biomonitoring is essential for linking exposure levels PFAS with their potential risks. Mass spectrometry-based analytical techniques extensively adopted the evaluation across various cohorts. However, challenges arising from use biological samples (e.g., plasma, serum, urine, etc.) necessitate ongoing research refinement methodologies. This review provides an overview current trends in mass approaches PFAS, including sample collection preparation, instrumental techniques. We also explore strategies overcome obtaining PFAS-free blank matrices address risk background contamination. Moreover, examines differing patterns regions by analyzing recent international cohort studies, specifically those conducted US China over past five years. Accordingly, several key gaps studies need be addressed moving forward highlighted.

Abstract Background Several legacy and emerging per- polyfluoroalkyl substances (PFAS) have been regulated around the world. There is growing concern over proliferation of alternative PFAS, as well PFAS precursors. Biomonitoring data for are critical assessing exposure human health risk. Methods We collected serum samples from 289 adult female participants in a 2018–2021 follow-up study Maternal-Infant Research on Environmental Chemicals (MIREC) Canadian pregnancy cohort. Samples were analyzed 40 using ultra-performance liquid chromatography–tandem mass spectrometry. For those compounds with > 50% detection, sum these compounds, we describe concentrations patterns according to sociodemographic obstetrical history characteristics. Results 17 out detected 7 97% samples. Median [95th percentile] (µg/L) highest PFOS (1.62 [4.56]), PFOA (0.69 [1.52]), PFNA (0.38 [0.81]), PFHxS (0.33 [0.92]). Geometric mean approximately 2-fold lower among more children (≥ 3 vs. 1), greater number breastfed ≤ longer lifetime duration breastfeeding (> 4 years 9 months), shorter time since last (≤ 8 years). observed similar PFOS, PFHpS, though differences between groups smaller. Concentrations higher “White” participants, while N-MeFOSE, N-EtFOSE, 7:3 FTCA, 4:2 FTS slightly reporting race or ethnicity other than “White”. legacy, alternative, precursor generally across levels age, education, household income, body index, menopausal status. Conclusions report first biomonitoring several PFAS. Our findings suggest that including alternatives, may be widespread. results consistent previous studies showing excretion pathways
