Perfluoroalkyl compound levels in breast milk of mothers in Riyadh, Kingdom of Saudi Arabia
Science
13 Mar 2026 | Nature
PFOA and PFOS were detected in a subset of breast-milk samples from mothers, indicating possible infant exposure through breastfeeding and highlighting the need for additional biomonitoring in the region.

Exploring per-and polyfluoroalkyl substances exposure risk in indoor air and PM2. 5: Correlations with respiratory health in university environments
Science
9 Mar 2026 | Env. Poll.
Indoor air and PM2.5 in university environments contained PFAS such as PFPeA, PFOA, PFOcDA, PFHxDA, and PFOS that were also detected in students’ exhaled breath condensate, suggesting inhalation exposure may be linked to respiratory inflammatory responses, though estimated exposure risk was low and results are based on limited observational correlations.

Spatial analysis of residential location at birth, PFAS in public water, and childhood cancers in Southern California (2000-2019).
Science
5 Mar 2026 | J Expo Sci Environ Epidemiol
Prenatal exposure to PFOA and PFOS in drinking water may be linked to increased risk of certain childhood cancers, particularly neuroblastoma and retinoblastoma, and may contribute to elevated cancer incidence in areas with contaminated water systems.

The differences in levels of poly- and perfluoroalkyl substances (PFASs) in the hair of wild terrestrial mammals with various feeding behaviour
Science
3 Mar 2026 | Sci Rep
PFAS were detected in the hair of wild mammals including wolves, red foxes, badgers, wild boar, and deer, with higher levels generally observed in predatory species such as wolves and foxes, suggesting environmental exposure and possible biomagnification through food webs.

Association between prenatal exposure to per-and polyfluoroalkyl substances and pubertal development in boys and girls in the Spanish INMA cohort
Science
26 Feb 2026 | Environ Res
Prenatal exposure to PFHxS, PFOS, PFOA, and PFNA may be associated with changes in the timing of puberty, with PFHxS linked to earlier adrenal maturation in girls and PFOS showing mixed patterns across sexes, supporting concerns that PFAS may influence endocrine pathways during development.

Per-and polyfluoroalkyl substances (PFAS) and menstrual cycle characteristics in midlife women: The Study of Women’s Health Across the Nation
Science
26 Feb 2026 | Reprod Toxicol
Higher serum concentrations of several PFAS, including PFOS, PFOA, PFNA, and PFHxS, were associated with greater variability in menstrual cycle length and shorter or lighter menstrual bleeding among midlife women.

Unveiling the toxic mechanism of nanoscale tire wear particles to algae: The interplay of particle size, photoaging, and co-existing PFOS
Science
20 Feb 2026 | Water Res
PFOS may amplify the toxicity of tire wear particles in freshwater algae, particularly after nanoscale particles undergo photoaging, which may enhance PFOS bioaccumulation and contribute to oxidative and metabolic stress.

Florida’s PFAS crisis is about to hit water bills hard
News
12 Feb 2026 | Florida Today
Florida’s cautious approach — waiting for federal guidance rather than adopting early, aggressive standards — helped the state avoid challenges seen in other regions, where systems became outdated shortly after installation.

Impact of Perfluorinated Organic Acids on Bacterial Ice Nucleators
Science
10 Feb 2026 | J Phys Chem B
In a lab study, PFOA and PFOS were found to interfere with bacteria that help initiate ice formation, which could potentially affect how freezing occurs in weather and ecological systems.

PFAS Contamination in Florida Estuarine Fishes: Levels, Patterns, and Estimated Human and Ecological Health Risks
Science
9 Feb 2026 | Environ Res
PFAS were detected across multiple estuarine fish species along Florida’s Atlantic coast, with PFOS often dominating tissue burdens and concentrations in some species potentially exceeding ecological benchmarks such as the EU biota standard and Canadian wildlife dietary guidelines, as well as human exposure thresholds including the EPA PFOS reference dose.

Temporal Trends of Per- and Polyfluoroalkyl Substances (PFASs) in Tibetan Plateau Sediment Cores (1952-2020): Tracking Global Emission History and Industrial Transformation in PFAS Production
Science
3 Feb 2026 | Environ Sci Technol
Sediment records from remote Tibetan Plateau lakes indicate PFAS deposition has increased over time and shifted toward short-chain compounds after 2000, likely reflecting global regulation-driven changes.

Validation of the U.S. Food and Drug Administration's Method for Detection of Per- and Polyfluoroalkyl Substances Analytes in Food and Feed: First Action 2025.06
Science
3 Feb 2026 | J AOAC Int
The U.S. FDA method was found to reliably measure 30 PFAS, such as PFOS, PFOA, PFNA, and PFHxS, across a range of human and animal foods.

PFAS in commercially available organic amendments and food-contact paper products
Science
1 Feb 2026 | Sci Total Environ
PFHxA and other short-chain PFCAs are dominant in composts and food-contact paper products, with PFOS dominant in biosolid-derived fertilizers, suggesting different waste sources may introduce distinct PFAS mixtures into soils used for gardening and agriculture.

High-resolution mass spectrometry analysis of legacy and emerging PFAS in oilfield environments: Occurrence, source, and toxicity assessment
Science
26 Jan 2026 | Toxics
Oilfield sites showed elevated and diverse PFAS contamination associated with displacement agents, and the PFOS substitute p-perfluorous nonenoxybenzenesulfonate appears similarly persistent and bioaccumulative while potentially linked to greater developmental cardiac toxicity than PFOS.

Evaluating Legacy and Emerging PFAS in Human Blood Collected from 2003 to 2021
Science
21 Jan 2026 | Environ Sci Technol
Analysis of U.S. blood samples suggests that although phased-out PFAS such as PFOS and PFOA have declined, replacement PFAS including 9Cl-PF3ONS, 6:2 DiPAP, and related phosphonate and phosphate compounds are increasingly detected, raising concerns since their sources, toxicity, and long-term health relevance remain poorly understood.
