New York state Legislature passes bill limiting PFAS in drinking water
Policy
10 Jun 2026
If signed into law by the Gov. Kathy Hochul, it would set requirements for drinking water to have levels below four parts per trillion for PFOA and PFOS, and below 10 ppt for three other types of PFAS, including PFNA, HFPO-DA known as GenX chemicals, and PFHxS.

Urine-to-blood partitioning of per-and polyfluoroalkyl substances in human biomonitoring: Implications for environmental exposure analysis and bioaccumulation assessment
Science
30 May 2026 | Molecules
Long-chain PFAS such as PFOS, PFOA, PFHxS, and PFNA bioaccumulation shows stronger blood retention due to binding with proteins such as human serum albumin and fatty acid-binding proteins.

US officially moves to dismantle drinking water PFAS regulations
News
21 May 2026 | Chemistry World
‘We are fixing that error with standards water systems can actually implement and that will hold up to scrutiny, while addressing PFOA and PFOS, two of the best-studied PFAS with well-documented health impacts,’ EPA Administrator Lee Zeldin stated.

PFAS contamination in agricultural systems near an active war zone: Sources, distribution, and crop uptake
Science
20 May 2026 | J. Hazard. Mater.
In the Middle East, PFAS were found in soil and potato plants near an active war zone; farming practices likely explained much of the soil contamination, while contaminated leaves may point to PFAS pollution moving through the air from conflict activity or regional air pollution.

Michigan Health Department releases findings about project on contaminants in firefighters’ blood
News
15 May 2026 | Click On Detroit
Confirmed concentrations for 13 types of PFAS, such as PFOA, PFOS and PFHxS, in the blood of Michigan firefighters.

Recommended toxicity reference values for PFOS and PFHxS in mammals and PFOS in birds
Science
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.

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.

Prenatal exposure to per- and polyfluoroalkyl substances (PFAS) and incidence of asthma and wheeze in childhood: A register-based cohort study in Ronneby, Sweden
Science
9 Apr 2026 | PLoS Med
PFAS, including PFOS, PFHxS, and PFOA from AFFF-contaminated drinking water, was associated with increased childhood asthma incidence, while no associations were observed at lower exposure levels, suggesting a possible threshold effect.

Associations of serum PFAS with COVID-19 antibody levels among fully vaccinated adults
Science
6 Apr 2026 | Environ. Res.
Higher serum PFAS levels were associated with lower COVID-19 antibody responses in vaccinated adults in a community with historic PFAS drinking water contamination, reinforcing the importance of reducing human exposure through effective policy measures such as establishing and enforcing strong drinking water standards.

Migration of per‐and polyfluoroalkyl substances in soil under rainfall simulation
Science
3 Apr 2026 | PLoS Med
Rainfall simulation experiments suggest that PFAS such as PFOS, PFOA, and PFHxS, may migrate primarily through leaching with additional transport via runoff, with wetting-dry cycles potentially redistributing PFAS to surface soils and enhancing mobilization.

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.

Early-life exposure to per-and polyfluoroalkyl substances and heavy metals and lower lung function in school-age children: A prospective cohort study
Science
23 Mar 2026 | Environmental Research
Early-life exposure to PFOA, PFOS, PFHxS, PFDA, and PFUnDA, measured in children’s blood alongside metals such as cadmium and mercury, was associated with reduced lung function at school age.

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.
