Nationwide distribution of per- and polyfluoroalkyl substances (PFAS) in road dust from India

2 Jun 2023 | Sci Total Environ

Total PFAS in road dust was highest in urban followed by suburban and rural areas, with the highest estimated daily intake of PFAS via road dust ingestion found to be in toddlers.

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.

Toxicological Mechanisms of Emerging Per-/poly-fluoroalkyl Substances: Focusing on Transcriptional Activity and Gene Expression Disruption

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.

Public Health Evaluation of PFAS Exposures and Breastfeeding: A Systematic Literature Review

25 May 2023 | Toxicol Sci

This systematic review highlights the need for future research to guide clinicians making recommendations on infant feeding.

Prenatal exposures to per- and polyfluoroalkyl substances and epigenetic aging in umbilical cord blood: The healthy start study

22 May 2023 | Environ Res

Higher PFDA concentrations in cord blood were associated with indicators of lower developmental maturity in infants.

Prenatal Exposure to Perfluoroalkyl Substances and Cognitive and Neurobehavioral Development in Children at 6 Years of Age

22 May 2023 | Environ Sci Technol

Prenatal exposure to multiple PFAS was associated with increased rates of attention problems.

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.

Sunrise of PFAS Replacements: A Perspective on Fluorine-Free Foams

15 May 2023 | ACS Sustain. Chem. Eng.

This paper provides a critical analysis of the present state of the various fluorine-free AFFF options that have been developed to date.

Per- and polyfluorinated alkyl substances (PFAS) in Pennsylvania surface waters: A statewide assessment, associated sources, and land-use relations

15 May 2023 | Sci Total Environ
