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.

Integrating target, nontarget analysis with machine learning to illuminate PFAS characteristics and health risks in Chinese cosmetics
Science
7 Mar 2026 | Environ Pollut
Analysis of commonly used Chinese cosmetics including face creams, lotions, sunscreen, mascara, eyeshadow, foundation, antiperspirant, shampoo, and facial wash detected multiple PFAS, including PFOA, PFNA, PFBS, PFHxS, and fluorotelomer sulfonates, with risk estimates suggesting dermal exposure from some items may exceed Texas safety thresholds.

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.

HFPO-TA provokes greater gill injury than PFOA in Opsariichthys bidens: A toxicological assessment of a next-generation PFAS substitute
Science
14 Feb 2026 | Environ Int
In a controlled fish study, the PFAS substitute HFPO-TA was associated with greater disruption of gill structure, antioxidant defenses, immune signaling, and mitochondrial regulation than PFOA, suggesting it may pose heightened ecological risk despite its use as a replacement.

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.

Atmospheric deposition and co-occurrence patterns of organophosphate flame retardants (OPFRs) and perfluorooctanoic acid (PFOA) in urban snow
Science
3 Feb 2026 | J AOAC Int.
Fresh snow in urban Romania was found to act as a temporary sink for multiple airborne pollutants, such as chlorinated organophosphate flame retardants and PFOA, with potential atmospheric deposition as a pathway for downstream exposure during snowmelt.

Exploring dog saliva as a non-invasive alternative to blood sampling for chemical exposome studies: analysis of synthetic phenolic antioxidants and PFAS.
Science
2 Feb 2026 | Front Vet Sci
In a pilot study of privately owned dogs, PFNA and both linear and branched PFOS were most frequently detected in saliva, while serum also contained PFOA, PFNA, PFDA, PFUnDA, PFBS, and PFHxS, indicating multi-congener PFAS exposure comparable to humans.
