[Opinion] Speaking the Same Language: The Need for Accurate and Consistent Reporting of Novel Per-and Polyfluoroalkyl Substances

18 Jul 2022 | ES&T

Recommendations presented in this viewpoint are encouraged for all PFAS researchers performing non-targeted analysis to prevent miscommunication and misidentification of PFAS compounds.

Association of increased risk of cardiovascular diseases with higher levels of perfluoroalkylated substances in the serum of adults

18 Jul 2022 | Environ Sci Pollut Res Int

A significant relationship between higher serum PFAS concentrations and an increased risk of cardiovascular disease was observed, mainly in males.

GenX Induces Fibroinflammatory Gene Expression in Primary Human Hepatocytes

15 Jul 2022 | Toxicology

GenX can interfere with metabolic pathways at lower doses and induce abnormal inflammation in human liver cells at higher doses.

Global distributions, source-type dependencies, and concentration ranges of per-and polyfluoroalkyl substances in groundwater

11 Jul 2022 | Sci Total Environ

This meta-analysis found that PFAS are detected in all media in all regions tested, which is a reflection of the large scale-use of PFAS, their persistence, and long-range transport.

Suspect screening and nontargeted analysis of per- and polyfluoroalkyl substances in representative fluorocarbon surfactants, aqueous film-forming foams, and impacted water in China

9 Jul 2022 | Environ. Int.

69 PFAS were identified in Chinese fluorosurfactants such as those used in aqueous film-forming foams, and high concentrations of neutral PFAS were found in polymer-based products.

Predicting Exposure to Perfluorinated Alkyl Substances (PFAS) among US Infants

9 Jul 2022 | Int J Environ Res Public Health.

Analysis of NHANES data found that lifetime exposure to PFAS begins in utero, and infant serum concentrations remain fairly stable from birth to at least age one, with the possible exception of PFOS.

Associations of prenatal exposure to perfluoroalkyl substances with preterm birth: A family-based birth cohort study

7 Jul 2022 | Environ Res

Higher family-level PFNA and PFDA exposure were associated with greater preterm birth risk, but the results on an individual level were contradictory.

Exposure to perfluoroalkyl substances and neurodevelopment in 2-year-old children: A prospective cohort study

7 Jul 2022 | Environ Int

PFAS exposure during early pregnancy was significantly associated with an adverse neurodevelopmental status at two years of age, raising a serious public health concern.

Association of Prenatal Exposure to Endocrine-Disrupting Chemicals With Liver Injury in Children

6 Jul 2022 | JAMA Netw Open

Prenatal exposure to mixtures of endocrine-disrupting chemicals, such as PFAS, organochlorine pesticides, and metals, may increase the risk for liver injury in childhood.

Widespread Occurrence of Non-Extractable Fluorine in Artificial Turfs from Stockholm, Sweden

6 Jul 2022 | ES&T L

Fluorinated substances in artificial turf were found to most likely be polymeric organofluorine (e.g., fluoroelastomer, polytetrafluoroethylene, and polyvinylidene fluoride), consistent with patent literature.

Volatilisation Potential of Per- and Poly- Fluoroalkyl Substances from Airfield Pavements and During Recycling of Asphalt

4 Jul 2022 | ET&C

Conditions during asphalt recycling and on airfield pavement may allow for the volatilization of PFAS, suggesting future research is needed for this unexplored mass loss mechanism and potential exposure pathway.
