Pygoscelis penguins as indicators of perfluoroalkyl substances pollution and global health risks - case study from King George Island (Western Antarctic)
Science
29 Jul 2025 | Environ Res
Scientists found that guano from penguins nesting near research stations on King George Island contained detectable PFAS chemicals (PFOS and PFPeS) while colonies farther away did not, revealing that even remote Antarctic wildlife is affected by localized human pollution.

Per- and polyfluoroalkyl substance concentrations during pregnancy and at birth and risk of childhood acute lymphoblastic leukemia
Science
25 Jul 2025 | Environ Res
Researchers analyzing blood samples from California newborns and their mothers found that babies with high levels of MeFOSAA, and to a lesser degree mothers with elevated pregnancy levels, faced roughly double the risk of developing childhood leukemia.

Scientists warn of toxic ‘forever chemicals’ in reusable period products
News
22 Jul 2025 | The Hill
“Since reusable products are on the rise due to their increased sustainability compared to single-use products, it’s important to ensure that these products are safe,” co-author Marta Venier, an associated professor at Indiana University, said in a statement.

These French villages have no more drinking water. The reason? PFAS pollution
News
18 Jul 2025 | Le Monde
Nearly 3,500 residents across 16 rural villages have been unable to drink tap water since July 10 due to a record-breaking contamination by PFAS, a group of toxic substances known as 'forever chemicals.'

Occurrence and tissue distribution of per- and polyfluoroalkyl substances (PFAS) in fishes from waterbodies with point and non-point sources in Massachusetts, USA
Science
17 Jul 2025 | Aquat Toxicol
In Massachusetts lakes and rivers, fish near known PFAS sources had much higher PFAS levels, especially PFOS. PFAS levels rose between 2020 and 2022, concentrating in blood more than in liver or muscle, and with lab tests showing signs of inflammation and other stress.

Association between prenatal exposure to per-and polyfluoroalkyl substances and blood pressure among preschool-aged children: The moderating effect of child-age and the mediating effect of inflammatory cytokine
Science
5 Jul 2025 | Ecotoxicol Environ Saf
Tracking 215 mother-child pairs in China, researchers found that prenatal exposure to common PFAS chemicals was associated with higher diastolic blood pressure in preschoolers, and that inflammatory signals in cord blood partly explained the effect, pointing to a subtle early-life pathway by which PFAS may increase the likelihood of later heart-disease risk.

‘Even if we stop drinking we will be exposed’: Parts of France have banned tap water. Is it a warning for the rest of Europe?
News
1 Jul 2025 | The Guardian
Forever chemicals have polluted the water supply of 60,000 people, threatening human health, wildlife and the wider ecosystem. But activists say this is just the tip of the PFAS iceberg.

Temporal changes in per and polyfluoroalkyl substances and their associations with type 2 diabetes
Science
1 Jul 2025 | Sci Rep
A 30-year Norwegian study found that blood levels of PFHpA, PFNA, PFHxS and PFHpS increased at a faster rate in people who later developed type 2 diabetes, indicating that exposure to these pollutants may play a role in the disease.

Development of chemical categories for per- and polyfluoroalkyl substances (PFAS) and the proof-of-concept approach to the identification of potential candidates for tiered toxicological testing and human health assessment
Science
30 Jun 2025 | Comput Toxicol
US EPA researchers mapped about 15,500 PFAS, grouped them into 128 structural categories, and pointed out the biggest data gaps—so regulators can target testing the most concerning types instead of addressing each chemical one by one.

“PFAS are everywhere” – Fears growing about PFAS in pesticides
News
28 Jun 2025 | Meg Wilcox
Blazer suspects that the PFAS pesticides are running off farm fields into waterways, where they may be contributing to a range of parasitic, viral and bacterial infections in fish that signal compromised immune functions.

Investigation of Perfluorooctanesulfonic Acid (PFOS) and Perfluorooctanoic Acid (PFOA) Isomer Profiles in Naturally Contaminated Food Samples
Science
25 Jun 2025 | J Agric Food Chem
Analysing PFOS- and PFOA-contaminated milk, deer meat, eggs and clams, FDA researchers found that calibrating with isomer-matched standards and quantifying branched and linear forms separately with a two-peak method decreased PFOS overestimation in branched-rich samples, while the distinctive isomer fingerprints traced some contamination to firefighting-foam runoff on dairy farms.

Enhanced immobilisation of per-and polyfluoroalkyl substances (PFAS) using a combination of sorbents and plants: A controlled rainfall simulation study
Science
23 Jun 2025 | Sci. Total Environ.
Lab tests show that mixing PFAS-tainted soil with powdered activated carbon and planting hardy ryegrass on top prevented about 90% of the PFAS from being washed away by heavy rain, pointing to a simple, inexpensive way to keep PFAS out of nearby waterways.

Association between exposure to bisphenols and per- and polyfluoroalkyl substances and behavioral problems among Chinese preschoolers
Science
23 Jun 2025 | Ecotoxicol Environ Saf
A study of 823 Chinese preschoolers found that children with higher combined urine levels of certain BPA-replacement plastics and PFHxS were about twice as likely to show behaviour issues, including hyperactivity, anxiety and conduct problems, highlighting that these may be regrettable substitutes.
