PFAS Vadose Zone Mass Discharge at an AFFF‐Impacted Site: 1. Validation Based on a Multiple Lines‐of‐Evidence Approach

Remediation Journal, Volume 36, Issue 2, Spring 2026.
ABSTRACT Questions have recently been raised about the suitability of using porewater samples collected with suction lysimeters to estimate per‐ and polyfluoroalkyl substances (PFAS) mass discharge in the vadose zone. Multiple lines of evidence were evaluated to determine if porewater samples collected during a data gaps investigation in the former ...

A Hexadecacationic Metal–Organic Cage for Anchoring Sulfonates: High‐Order Binding of Di‐ and Trisulfonates and High‐Performance Removal of Perfluorosulfonates from Water

Advanced Science
Developing synthetic hosts capable of binding sulfonate anions or sequestering perfluorosulfonates is highly important. In this work, the self‐assembly of a tripyridinium‐tricarboxylate ligand with Cp2ZrCl2 (Cp = η5‐C5H5) is reported, yielding a highly ...

Per- and Polyfluoroalkyl Substances (PFAS) Mixture during Pregnancy and Postpartum Weight Retention in the New Hampshire Birth Cohort Study (NHBCS)

Toxics, 2023
Per- and polyfluoroalkyl substances (PFAS), widely used in industrial and consumer products, are suspected metabolic disruptors. We examined the association between a PFAS mixture during pregnancy and postpartum weight retention in 482 participants from ...

Cot Statement On Perfluorooctane Sulfonate (Pfos)

, 2014
The Scientific Advisory Committee on Nutrition is reviewing scientific evidence that bears on dietary recommendations for infants and young children. The COT is considering risks that might need to be taken into account. This statement summarises the evidence on risks from PFOS in the infant diet and the conclusions of the COT.

Mitochondrial iron overload mediated by cooperative transfer of plasma membrane ATP5B and TFR2 to mitochondria triggers hepatic insulin resistance under PFOS exposure

Ecotoxicology and Environmental Safety, 2023
In general populations, insulin resistance (IR) is related to perfluorooctane sulfonate (PFOS), a persistent organic pollutant. However, the underlying mechanism remains unclear. In this study, PFOS induced mitochondrial iron accumulation in the liver of

PFOS induces behavioral alterations, including spontaneous hyperactivity that is corrected by dexamfetamine in zebrafish larvae [PDF]

, 2014
Perfluorooctane sulfonate (PFOS) is a widely spread environmental contaminant. It accumulates in the brain and has potential neurotoxic effects. The exposure to PFOS has been associated with higher impulsivity and increased ADHD prevalence.

Contaminants of emerging concern in agricultural soils: Current understanding, overlooked issues, and future priorities

PLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 792-810, May 2026.
Contaminants of emerging concern (CECs) in agriculture represent a growing global challenge for food safety and public health. In this review, we synthesized evidence on how substances such as pharmaceuticals, microplastics, and per‐ and polyfluoroalkyl substances (PFAS) enter soils, accumulate in crops, and affect ecological and human health. We found
