• Associations of single and multiple perfluoroalkyl substances exposure with folate among adolescents in NHANES 2007-2010

  Science

  15 Aug 2022 | Chemosphere

  Exposure to PFOS, PFOA, PFNA, and PFDA was associated with lower blood folate concentrations.

• Outside the Safe Operating Space of a New Planetary Boundary for Per-and Polyfluoroalkyl Substances (PFAS)

  Science

  2 Aug 2022 | ES&T

  PFAS have been detected at unsafe levels in rain globally, leading to the conclusions that the spread of PFOS, PFOA, PFHxS, and PFNA in the atmosphere has exceeded levels of concern for chemical pollution and that PFAS uses and emissions should be rapidly restricted.

• Increasing Accumulation of Perfluorocarboxylate Contaminants Revealed in an Antarctic Firn Core (1958–2017)

  Science

  26 Jul 2022 | ES&T

  PFCA and PFBA accumulation in snow increased, and although chemical fluxes of PFOA and PFNA peaked in 2009–2013, there is little evidence of a decline in PFAAs despite supposed recent global curtailments in their production.

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

  Science

  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.

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

  Science

  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.

• Global patterns and temporal trends of perfluoroalkyl substances in municipal wastewater: A meta-analysis

  Science

  30 Jun 2022 | Water Res

  Serum PFHxS, Sm‐PFOS, n‐PFOS, n‐PFOA, and PFNA concentrations were increased in at least two of four fire departments compared to NHANES national data.

• Vermont-wide Assessment of Anthropogenic Background Concentrations of Perfluoroalkyl Substances in Surface Soils

  Science

  25 Jun 2022 | J. Hazard. Mater.

  PFOS was the most dominant substance followed by PFNA and PFOA in all soil samples.

• Estimated daily intake of per- and polyfluoroalkyl substances related to different particle size fractions of house dust

  Science

  6 Jun 2022 | Chemosphere

  Children’s estimated daily intake for the sum of PFOA, PFNA, PFHxS, and PFOS from house dust exposure is close to the tolerable weekly intake value presented by the European Union.

• Sorption of Per-and Polyfluoroalkyl Substances (PFAS) using Polyethylene (PE) microplastics as adsorbent: Grand Canonical Monte Carlo and Molecular Dynamics (GCMC-MD) studies

  Science

  17 May 2022 | Int. J. Environ. Anal. Chem.

  Several PFAS were found to easily sorb on to polyethylene microplastics, especially as pollutant concentration increased.

• Invited Perspective: PFAS and Liver Disease: Bringing All the Evidence Together

  Science

  2 May 2022 | EHP

  The evidence of liver toxicity due to PFAS exposure by Costello et al. underscores the urgent need for further research and for immediate and reasonable public health action.

• Exposure to per- and Polyfluoroalkyl Substances and Markers of Liver Injury: A Systematic Review and Meta-Analysis

  Science

  2 May 2022 | Environ Health Perspect

  ​​There is consistent evidence for PFAS liver toxicity from rodent studies, supported by associations of PFAS and markers of liver function in human studies.

• Association between serum per-and polyfluoroalkyl substances concentrations and common cold among children and adolescents in the United States

  Science

  19 Apr 2022 | Environ. Int.

  In children, blood concentrations of PFAS mixtures and individual PFAS were associated with higher odds of common cold, especially in males.

• Per-and polyfluoroalkyl substances and incident diabetes in midlife women: the Study of Women’s Health Across the Nation (SWAN)

  Science

  19 Apr 2022 | Diabetologia

  This study suggests that PFAS may increase diabetes risk in midlife women.

• Healthy eating index and diet diversity score as determinants of serum perfluoroalkyl acid (PFAA) concentrations in a national survey of Swedish adolescents

  Science

  6 Apr 2022 | Environ. Res.

  Adolescents with a healthy dietary pattern had on average higher PFAA serum levels.

• Temporal Trends of Organochlorine- and Perfluorinated Contaminants in a Terrestrial Raptor in Northern Europe over 34 Years (1986-2019)

  Science

  31 Mar 2022 | Environ Toxicol Chem

  Most legacy organochlorines and PFOS have not reached lower, stable background levels, and voluntary elimination of PFCAs still have not resulted in declining levels in tawny owls in central Norway.
