Per-and polyfluoroalkyl substances suppress macrophage alternative activation to disrupt hepatic lipid metabolism
Science
29 May 2025 | Chem. Res. Toxicol.
Experiments in cells and mice show that two common PFAS, PFOA and PFUnDA, damage liver immune cells that maintain fat processing, leading to enlarged livers and body‑wide lipid imbalances, evidence that PFAS pollution could silently impact metabolic health.

[Dissertation] Permitting pollution: The production of science, policy, and the State in Environmental Regulatory Policy on Industrial Pollution in the United States
Science
27 May 2025 | American University
Archival records and ethnographic interviews reveal that tight corporate–regulator relationships in the United States let industrial polluters steer science and policy, forcing communities in places like North Carolina and Louisiana to fight for themselves and showing that lasting environmental protection will require community‑centered, bottom‑up reforms rather than today’s permit system.

Per-and polyfluoroalkyl substances (PFAS) in placental compartments: Histopathological and toxicological data integration in an Italian cohort
Science
27 May 2025
Placenta samples from Italian pregnancies almost always contained multiple PFAS chemicals, and higher levels were tied to blood‑flow problems and abnormal growths, suggesting these persistent pollutants may disrupt normal placental function and threaten pregnancy health.

Unregulated and Regulated PFASs in Bottled and Tap Water: Occurrence, Co-Occurrence Patterns, and Implications for Human Health and Regulatory Frameworks
Science
27 May 2025 | J Xenobiot
Analysis of 45 Romanian drinking water samples highlight the importance of ongoing surveillance of currently regulated as well as emerging PFAS and calls for more stringent regulatory thresholds and improvements in water treatment practices.

Geospatial and socioeconomic factors of PFAS contamination in private drinking water wells: Insights for monitoring and management
Science
27 May 2025 | J Environ Manage
Citizen‑science testing of 167 private wells across Pennsylvania found that about two‑thirds contained detectable PFAS, nearly one in five exceeded new health‑based limits, and the highest levels appeared in densely developed areas—signaling a need for focused testing and support for vulnerable communities.

The Biggest Chemical Cover-Up In History Was Kept Hidden For Years
News
24 May 2025 | IFL Science
Up to 99 percent of people have “forever chemicals” in their bodies, where they linger indefinitely and potentially cause a host of health conditions. Disturbingly, the manufacturers of these chemicals were aware of the risks and deliberately concealed them, following a playbook strikingly similar to that of Big Tobacco.

Per- and polyfluoroalkyl substances (PFAS) profiles in primary and secondary landfill leachates: Indications of transformation, liner interactions, and other PFAS sources
Science
24 May 2025 | J Hazard Mater
Tests at three modern, double‑lined Florida landfills showed that the supposedly isolated liquid beneath the main liner still contained thousands to tens of thousands of nanograms‑per‑litre of assorted PFAS, often rivaling or exceeding levels in the primary leachate, revealing that “forever chemicals” can slip through liners, transform, and build up despite today’s best landfill safeguards.
