Marpe v. Tonoga, Inc.: limiting Frye hearings and clarifying expert causation standards in New York PFOA toxic-tort litigation
News
20 Dec 2026 | Casemine
This is a significant procedural and evidentiary ruling in New York toxic-tort law in the burgeoning litigation over PFOA contamination in Hoosick Falls and surrounding areas. The court formally recognized that the methodologies used by key PFOA experts are not “novel” and have already been accepted in other courts.

Evaluating Legacy and Emerging PFAS in Human Blood Collected from 2003 to 2021
Science
21 Jan 2026 | Environ Sci Technol
Analysis of U.S. blood samples suggests that although phased-out PFAS such as PFOS and PFOA have declined, replacement PFAS including 9Cl-PF3ONS, 6:2 DiPAP, and related phosphonate and phosphate compounds are increasingly detected, raising concerns since their sources, toxicity, and long-term health relevance remain poorly understood.

The occurrence, sources, and health risks of per-and polyfluoroalkyl substances (PFAS) in pm 2. 5 in Shihezi, a typical inland arid industrial city
Science
19 Jan 2026 | Atmos. Pollut. Res.
PFAS were widely detected in fine particulate air pollution in an arid industrial city, dominated by short chain compounds linked to industrial emissions and atmospheric transformation, suggesting that airborne PFAS exposure may be underestimated when total human exposure, particularly for children.

Occurrence and sources of organic contaminants of emerging concern in indoor dust: A global perspective
Science
14 Jan 2026 | J Hazard Mater
A global review finds PFAS commonly in indoor dust from homes, offices, and schools, particularly in North America, Europe, and East Asia, and identifies PFOS and PFOA as persistent legacy compounds alongside increasingly reported short-chain PFAS and precursors, suggesting ongoing indoor exposure despite regulation.

As EPA tries to loosen PFAS rules, NC regulators inch toward statewide protections
Policy
9 Jan 2026
Members of the Environmental Management Commission expressed the need for some urgency in moving forward with the development of statewide rules on Thursday. The group took up two sets of “monitoring and minimization rules”: one for three types of PFAS – PFOS, PFOA and GenX – and another for 1,4-Dioxane.

$27M DuPont PFAS contamination class action settlement
News
5 Jan 2026 | Top Class Actions
DuPont agreed to a $27 million class action lawsuit settlement to resolve claims it contaminated drinking water in Hoosick Falls, New York, with PFOA.

An integrated in vitro and in silico testing strategy applied to PFAS inhibition of antibody production to define a tolerable daily intake
Science
3 Jan 2026 | Toxicol Lett
PFOS, PFOA, PFNA, and PFHxS, may inhibit antibody production, with modeled human-equivalent effect doses that are similar to or lower than existing European Food Safety Authority health-based guidance values.

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.

Formation of perfluorocarboxylic acids (PFCAs) from the incomplete thermal decomposition of perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA
Science
16 Dec 2025 | ACS ES&T Air
PFOS and PFOA thermal treatment may consistently produce multiple perfluorocarboxylic acids and volatile fluorinated byproducts at suboptimal temperatures despite near-complete parent destruction, highlighting potential emissions concerns and uncertainties about the specific formation pathways.

Mediating role of proteomics in the association between per-and polyfluoroalkyl substance exposure and blood pressure in youth
Science
15 Dec 2025 | Environ Pollut.
PFOA, PFNA, PFOS, PFHxS, and PFHpS, exposure may be associated with higher blood pressure in youth through protein changes (particularly galectin-3) involving inflammatory and scarred tissue.

Investigating anaerobic digestion microbiome resilience to high PFOA and PFOS mixtures during cometabolism
Science
8 Dec 2025 | Bioresour. Technol.
High levels of PFOA and PFOS may interfere with how microbes create biogas during anaerobic digestion, which is important for waste-treatment policy because it suggests these chemicals can disrupt sludge processing while showing no clear signs of degradation.

Assessing the impact of perfluoroalkyl substances on liver health: A comprehensive study using multi-donor human liver spheroids
Science
8 Dec 2025 | Environ. Int.
PFHxS, PFOA, PFOS, and PFNA may interfere with liver function in different ways depending on the specific chemical and the sex of the donor cells, potentially contributing to fat buildup in the liver, weakened immune activity, and molecular changes linked to cancer development.

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.
