Fate, bioaccumulation, and toxic responses of PFOA, PFOS, and GenX in the paddy soil-rice system across the full growth cycle
Science
1 Jan 2026 | J Hazard Mater
Analysis of a full growth cycle study in paddy soil suggests that PFOA, PFOS, and the replacement PFAS GenX may disrupt rice growth and induce oxidative stress. GenX is showing greater upward movement into edible tissues, highlighting potential food-chain relevance and informing proposed soil safety thresholds for rice cultivation.

Unforeseen risks due to the use of fluorinated materials for per-and polyfluoroalkyl substance removal
Science
30 Dec 2025 | Nature
Researchers report that fluorinated materials used for PFAS removal may inadvertently release additional fluorinated compounds during production, use, or disposal, suggesting that non-fluorinated alternatives offer safer options for treatment technologies.

Shaw Industries invents testing methodology to detect PFAS
News
19 Dec 2025 | Floor Covering Weekly
“What we discovered is that drinking water testing wasn’t accurate for soaps, oils, resins and other solid materials—really anything other than drinking water. An adequate testing methodology didn’t exist, so we invented one.”

Reevaluating PFAS exposure risks from marine fish
Science
18 Dec 2025 | Science
A global modeling analysis finds that legacy PFAS exposure from marine fish may now be low for most countries due to production phaseouts, yet remains higher in places with very high seafood intake such as Greenland and Denmark, offering important insight for refining fish consumption guidance and noting where potential risk persists.

Childhood exposure to per-and polyfluoroalkyl substances in educational environments: Arising from stationery and implications for health
Science
15 Dec 2025 | J. Environ. Chem. Ecotoxicol.
Several products purchased in China released measurable PFAS including precursors that increased after oxidation and maximum estimated intake from hand to mouth contact with some pen grips approaching the European Food Safety Authority tolerable intake for children.

Development and validation of an LC-MS/MS method for simultaneous determination of 39 PFAS in soil samples: applications to playgrounds in Attica, Greece
Science
4 Dec 2025 | Anal Bioanal Chem
An optimized research method was found to be a useful tool for environmental and public-health decision making by reliably detecting 39 PFAS in playground soils, and the results suggest that some PFAS levels may potentially exceed a precautionary child-health screening value of about 100 ng per kg of body weight per day.

Assessing nondietary exposure to per-and polyfluoroalkyl substances (PFASs) in firefighters using silicone wristbands
Science
3 Dec 2025 | Environ Health (Wash)
A longitudinal study using silicone wristbands and blood measurements found firefighters to have widespread exposure to specific PFAS such as PFOA, PFOS, PFHxS, and precursor compounds, with compounds like MeFBSE potentially linked to firefighting activities and increasing with time spent at fires, highlighting occupational and ambient exposure pathways.

EWG to Lee Zeldin: PFAS pesticides are bad news, not ‘fake news’
News
2 Dec 2025 | EWG
The EPA uses a narrow definition of PFAS that excludes PFAS pesticides it’s recently approved. Under this definition, only three currently approved pesticide active ingredients would be considered PFAS: broflanilide, pyrifluquinazon and noviflumuron.

Lab-scale insights into the environmental fate of emerging contaminants from airport runoff
Science
1 Dec 2025 | J Contam Hydrol.
Laboratory evidence indicates that only some contaminants in airport runoff are naturally diminished during contact with sediments, whereas PFAS remain largely persistent, raising concerns about whether soil aquifer treatment can adequately protect groundwater from these chemicals.

Assessing PFAS exposure in Rocky Mountain elk (Cervus canadensis nelsoni) populations adjacent to the former Rocky Flats nuclear site: A preliminary analysis.
Science
1 Dec 2025 | PLoS One
Preliminary analysis finds that PFOS was consistently detected in elk livers at both Rocky Flats and control sites while PFOA was not detected, suggesting that PFOS may accumulate in elk regardless of proximity to known contamination sources and highlighting potential wildlife exposure pathways and implications for game consumption.

Officials make disturbing discovery after drawing blood from residents near US military base: 'We've had it'
News
29 Nov 2025 | Yahoo!News
What was most staggering in the discovery, however, was that 26% of plume area participants had PFAS levels in the highest concentration tier, meaning they were exposed to nearly ten times the amount of the common group.

Non-destructive surface sampling of PFAS exposure on firefighter protective gears: Potential implications for occupational exposure
Science
27 Nov 2025 | J. Hazard. Mater.
Firefighter turnout gear and self-contained breathing apparatus surfaces may contain notable levels of PFAS, particularly 6:2 FTS, indicating potential occupational exposure through skin contact and inhalation underscoring a need for improved monitoring while noting that minor PFAS signals in blanks may introduce some uncertainty.

The EPA is embracing PFAS pesticides. These are the health risks
News
26 Nov 2025 | Time
The approval of the two chemicals is part of a larger pattern by the Trump Administration to broaden the use of PFAS-containing pesticides on industrial and private farms across the country.

Arsenic, Cadmium, Lead, Mercury, and PFAS Exposure During Pregnancy or Lactation and Respective Concentrations in Human Milk: Systematic Review
Science
26 Nov 2025 | Environ Res
Evidence from 46 studies suggests that higher maternal exposure to lead, mercury, PFOA, and PFOS may be linked with higher concentrations of the same contaminants in human milk, potentially exposing infants during critical development windows.
