Distribution of per- and polyfluoroalkyl substances in renal vascular tissues from donors after brain death and association with post-transplant delayed graft function risk
Science
9 Jul 2026 | Environ Pollut
Higher concentrations of PFOA, PFNA, PFDA, PFUnDA, PFHxS, PFOS, and 6:2 Cl-PFESA in donor renal artery tissue were associated with an increased risk of delayed graft function after kidney transplantation.

Occupation and serum concentrations of per- and polyfluoroalkyl substances: Data from the 2013 to 2014 National Health and Nutrition Examination Survey
Science
6 Jul 2026 | Ann Work Expo Health
PFAS serum levels were highest in construction/extraction, installation/maintenance/repair, protective services, and some manufacturing/transportation-related groups, with PFOA, PFOS, PFHxS, and PFNA making up over 70% of total PFAS body burden and more than 20% of some worker groups exceeding the NASEM high-risk threshold.

Multiple contaminant detection in commercially available chicken-based cat kibbles in Italy
Science
10 Jun 2026 | Front Vet Sci
PFAS were detected in several chicken-based cat kibbles sold in Italy, including PFPeA, PFHxA, and PFNA, adding to concerns that pet food may be an overlooked source of chronic PFAS exposure for cats. PFOA and PFOS were either absent or below quantification limit.

Advancing PFAS biomonitoring in hair: Rapid analytical method and global comparison of US exposure
Science
10 May 2026 | Drug Test. Anal.
PFHpA was detected in every New York hair sample tested, while PFOA and PFNA appeared less often. This analytical technique may help track longer-term PFAS exposure and regional differences in contamination patterns.

PFAS exposure perturbs lipid metabolism to promote gestational diabetes mellitus and alter growth trajectories via distinct mechanisms in singletons and twins
Science
3 May 2026 | Environ Sci Technol
PFAS exposure increased gestational diabetes risk in both single-baby pregnancies and twins, while twins showed a stronger mixture effect driven mainly by PFNA and emerging PFAS (e.g., HFPO-DA) with bile acid–related pathways, while single-baby pregnancies were more influenced by PFOA through broader lipid and amino acid metabolism disruptions.

Serum PFAS in aircraft rescue and firefighting (ARFF) firefighters from six US airport fire departments
Science
25 Apr 2026 | Am. J. Ind. Med.
Workplace changes, such as improved handling of PFAS-containing foams, greater use of personal protective equipment like gloves, safer foam -use practices, and increased training and awareness, were associated with lower levels of PFHxS, PFNA, PFDA, and overall PFAS in the blood.

Diet, lifestyle, and sociodemographic influences on serum concentration of PFASs: Insights from human biomonitoring in Switzerland.
Science
17 Apr 2026 | Environ Int
Human biomonitoring in Swiss adults suggests PFAS in the body are largely driven by older, persistent compounds and tend to increase with age and in males, while higher levels are linked to exposures like local freshwater fish consumption and certain product uses, indicating that multiple, compound-specific pathways contribute to overall PFAS burden.

Chemical exposome patterns in mothers and children across urbanisation levels in five European birth cohorts
Science
2 Apr 2026 | J Expo Sci Environ Epidemiol
Urban versus non-urban living may shape exposure to multiple chemicals during pregnancy and childhood, with some substances like phenols and phthalates higher in urban areas while PFAS associated with agricultural practices such as PFOA, PFOS, PFNA, PFHxS, and PFUnDA may be higher in non-urban children.

Impact of regulatory actions to establish maximum contaminant levels on per-and polyfluoroalkyl substances in New Jersey public water systems
Science
30 Mar 2026 | Environ. Int.
State-level actions to establish drinking water limits for PFOA, PFOS, and PFNA were associated with substantial reductions in contamination levels in New Jersey public water systems, suggesting such regulatory approaches may effectively reduce exposure.

Atmospheric transport and deposition of PFAS in East Antarctica: Evidence from snow transect measurements and a multidecadal record
Science
20 Mar 2026 | Science Advances
PFOA, PFNA, TFA, PFPrA, and HFPO-DA were found to persist in Antarctic snow due to long-range atmospheric transport and ongoing formation from precursor chemicals.

Per-and polyfluoroalkyl substances and adolescent bone mineral density: Assessing periods of susceptibility
Science
17 Mar 2026 | J Endocr Soc.
Higher serum concentrations of PFOA, PFOS, PFHxS, and PFNA during childhood were associated with changes in adolescent bone mineral density, with consistent links between PFOA exposure and lower density in cortical bone.

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.

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.

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.
