Occurrence and interbrand variability of per-and polyfluoroalkyl substances in bottled water marketed in France
7 May 2026 | ACS ES&T Water
In French bottled and tap water samples, TFA was found consistently at about 50 to 1,300 ng/L in bottled water and 560 to 2,100 ng/L in tap water, while the 20 PFAS currently monitored under European drinking water rules were mostly absent or below the 100 ng/L combined water quality limit.
Recommended toxicity reference values for PFOS and PFHxS in mammals and PFOS in birds
5 May 2026 | Integr Environ Assess Manag
PFOS and PFHxS are associated with population-level reproductive effects at higher exposures, including reduced offspring survival, increased stillbirths, and decreased hatching success, with PFOS showing greater toxicity, while also establishing chronic-dose toxicity reference values to support ecological risk assessments.
PFAS exposure perturbs lipid metabolism to promote gestational diabetes mellitus and alter growth trajectories via distinct mechanisms in singletons and twins
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.
A rank order of 26 North American fish species by propensity for PFAS bioaccumulation
30 Apr 2026 | IEAM
PFAS bioaccumulation in fish was found to be species specific, with fish like Brown Trout and Smallmouth Bass consistently showing the highest contamination levels and serving as key indicators of elevated exposure risk.
Use of a capillary blood collection device to monitor exposure to per- and polyfluoroalkyl substances (PFAS) in Veterans living in proximity to potential sources of environmental contamination
30 Apr 2026 | J Expo Sci Environ Epidemiol
PFAS were widely detected and closely matched traditional blood tests, with higher levels linked to factors like age, sex, and especially drinking water source, indicating this method can effectively track real-world exposure patterns.
FDA’s infant formula product testing results
29 Apr 2026 | U.S. FDA
The agency tested over 300 infant formula samples for lead, mercury, cadmium, arsenic, pesticides (including glyphosate and glufosinate), PFAS (with PFOS most frequently detected), and phthalates.
Remediating and reducing the environmental impact of fire suppression systems contaminated with per-and polyfluoroalkyl substances: Perspectives on current guidelines.
27 Apr 2026 | Fire Safety Journal
A technical review proposes practical guidance for cleaning PFAS-contaminated fire suppression systems, showing that PFAS from AFFF can persist and rebound from pipes and components due to sorption and slow desorption processes, which may limit the effectiveness of simple rinsing and highlight the need for system-specific remediation strategies and evolving policy guidance.
Multi-media occurrence, bioaccumulation, and exposure assessment of PFAS across a Midwestern US State
27 Apr 2026 | Environ. Res.
A statewide study suggests PFAS, including PFOS and other legacy and newer compounds, are found across air, drinking water, fish, and people in Indiana, where they may build up in food webs and show patterns linked to water system size and community demographics, highlighting multiple exposure pathways and potential environmental justice concerns.
Microplastic-associated pollutants in prostate carcinogenesis and plant-based chemo-preventive strategies
27 Apr 2026 | Drug Chem Toxicol
Microplastics can carry PFAS and other toxic chemicals into the body and build up in prostate tissue, potentially increasing localized exposure and contributing to processes linked to cancer.
Extractable organofluorine (EOF) and target PFAS, including trifluoroacetic acid (TFA), in human serum from a Norwegian cohort, with a case study on the impact of fluorinated pharmaceuticals
26 Apr 2026 | Environ. Int.
Current PFAS measurements may miss a substantial share of human exposure, as up to about half or more of fluorinated compounds in blood remain unidentified, with TFA often the most abundant detected PFAS and additional contributions from sources like fluorinated pharmaceuticals increasing overall body burden.
Serum PFAS in aircraft rescue and firefighting (ARFF) firefighters from six US airport fire departments
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.
PFAS co-positivities identified in more than 10,000 serum/plasma samples.
24 Apr 2026 | J. Occup. Environ. Hyg.
Analysis of over 10,000 blood samples contained combinations of PFHxS, PFOA, PFOS, PFNA, and PFHpS, highlighting that real-world exposure typically involves complex mixtures rather than single substances.
[Viewpoint] Allowing unlimited PFAS manufacturing contradicts the core intention of the European Union’s PFAS restriction proposal
23 Apr 2026 | Environ. Sci. Technol.
The European Union’s proposed PFAS restriction may still allow continued production that leads to ongoing, unbounded emissions over time, ultimately undermining its goal of protecting human health and the environment.
Wastewater treatment facilities as underappreciated point sources for per-and polyfluoroalkyl substances and microplastics: A critical perspective
22 Apr 2026 | Chem. Mater.
Treatment processes may redistribute PFAS rather than fully remove them, with shorter-chain compounds remaining in the aqueous phase while longer-chain forms partition to solids or foams, and microplastics potentially acting as transport vehicles.
Diet, lifestyle, and sociodemographic influences on serum concentration of PFASs: Insights from human biomonitoring in Switzerland.
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.
