The Devil they Knew: Chemical Documents Analysis of Industry Influence on PFAS Science
1 Jun 2023 | Annals of Global Health
The lack of transparency in industry-driven research on industrial chemicals, including industry strategies to suppress critical science, has significant legal, political, and public health consequences.
Identifying Unknown Fluorine-Containing Compounds in Environmental Samples Using 19F NMR and Spectral Database Matching
1 Jun 2023 | ES&T
The fluorine NMR spectrum of hundreds of fluorinated compounds was documented and used to determine the concentration of PFAS at an AFFF-contaminated site.
Per- and Polyfluoroalkyl Substances in Personal Hygiene Products: The Implications for Human Exposure and Emission to the Environment
1 Jun 2023 | Environ Sci Technol
Paper diapers contained the highest summed PFAS concentrations, followed by sanitary pads then menstrual cups; associated PFOA dermal absorption was estimated to contribute to more exposure than dust inhalation exposure.
[Report] PFAS in Paints: Per- and Polyfluoroalkyl Substances in Paints
31 May 2023 | HBN

30 May 2023 | Toxicology
This review covered in vivo and in vitro studies, summarizing the hepatotoxicity of emerging PFAS and their interference with the endocrine system, including reproductive, developmental, and thyroid toxicity.
Perfluorohexanesulfonic acid (PFHxS) induces oxidative stress and causes developmental toxicities in zebrafish embryos
27 May 2023 | J Hazard Mater
PFHxS was found to accumulate in zebrafish embryos and cause physiological and developmental toxicities.
Diffusion and partitioning of different PFAS compounds through thermoplastic polyurethane and three different PVC-EIA liners
26 May 2023 | Sci Total Environ
PFAS was found to diffuse through certain membranes used in landfills, potentially leading to groundwater contamination.

Association between PFAS congeners exposure and asthma among US children in a nationally representative sample
17 May 2023 | Environ Geochem Health
Exposure to some PFAS in male children from 3-7 years old was associated with asthma.
Influence of convective and stratiform precipitation types on per-and polyfluoroalkyl substance concentrations in rain
16 May 2023 | Sci. Total Environ.
PFAS concentrations in precipitation appear to be controlled by the type and magnitude of precipitation events as well as the type of PFAS, whereas population density is a poor predictor of PFAS in precipitation.
Centurial Persistence of Forever Chemicals at Military Fire Training Sites
15 May 2023 | ES&T
This work highlights the importance of unregulated and overlooked precursors for total PFAS exposure near AFFF releases and their role in sustaining high concentrations of regulated PFAS–up to 2000 times more than regulatory limits even decades after AFFF use ceased.
