• Human health risk-based soil generic assessment criteria of representative perfluoroalkyl acids (PFAAs) under the agricultural land use in typical Chinese regions

  Science

  14 Aug 2023 | Environ Pollut

  This study provides a technical reference for deriving soil generic assessment criteria for PFAAs and found that the dominant exposure pathway for PFBA and PFBS in some regions of China was vegetables and attached soil.

• Environmental exposure and ecological risk of perfluorinated substances (PFASs) in the Shaying River Basin, China

  Science

  19 Jul 2023 | Chemosphere

  PFAS exposure via inhalation of particulate matter was found to be dominated by low levels of PFSAs and PFCAs, but inhalation exposure is still important due to its long-term and cumulative nature.

• Perfluorinated Compounds (PFCs) in River Waters of Central Italy: Monthly Variation and Ecological Risk Assessment (ERA)

  Science

  6 Apr 2023 | Arch Environ Contam Toxicol

  PFOS concentrations were classified as medium to high risk for the aquatic environment in all river samples, which also frequently contained PFBA, PFPeA, PFHxA, and PFOA, especially in summer months.

• PFAS: forever chemicals—persistent, bioaccumulative and mobile. Reviewing the status and the need for their phase out and remediation of contaminated sites

  Science

  23 Mar 2023 | ESEU

  The authors of this review conclude that substituting individual PFAS recognized as hazardous with other possibly equally hazardous PFAS with virtually unknown chronic toxicity should not be a solution.

• ECHA seeks input on proposed PFAS restriction

  Policy

  22 Mar 2023

  The European Chemicals Agency invites interested parties to send in scientific and technical information on the manufacture, placing on the market and use of per- and polyfluoroalkyl substances (PFAS) by 25 September 2023.

• EU floats plan that would ban virtually every PFAS currently on the market

  News

  9 Feb 2023 | Chemistry World

  The five countries want to essentially ban the entire class of more than 10,000 chemicals in a single stroke, including their production, use, and sale, and the impact would be significant.

• Analytical method interferences for perfluoropentanoic acid (PFPeA) and perfluorobutanoic acid (PFBA) in biological and environmental samples

  Science

  30 Dec 2022 | Chemosphere

  Researchers recommend adjustments to analytical methods investigating PFBA and PFPeA due to chemical interferences from fatty acids in biological and environmental samples.

• Legacy and emerging airborne per- and polyfluoroalkyl substances (PFAS) collected on PM2.5 filters in close proximity to a fluoropolymer manufacturing facility

  Science

  9 Nov 2022 | Environ Sci Process Impacts

  Twelve emerging and ten legacy PFAS compounds were detected in aerosol samples around a fluoropolymer manufacturing facility at concentrations higher than at regional background sites, suggesting the manufacturing facility as the local source for these compounds.

• [Blog] Quibble with Kibbles: ‘Forever chemicals’ in pet food packaging add to perils at home

  News

  3 Nov 2022 | EWG

  The toxic “forever chemicals” known as PFAS create health hazards at home, since they’re used in everyday items like cookware and cosmetics – and new EWG research finds some popular pet food packaging can be yet another way we’re exposed to the perils of PFAS.

• Swimming with PFAS in public and private pools

  Science

  11 Oct 2022 | Chemosphere

  PFBA, PFHxA, PFHpA, PFOA, PFNA and PFBS were detected in every pool sample with most PFOA and PFOS levels above the new US EPA drinking water health advisory limits.

• Uptake of per-and polyfluoroalkyl substances (PFAS) by soybean across two generations

  Science

  3 Oct 2022 | J. Hazard. Mater. Adv.

  Considering widespread PFAS contamination and the ability of soybean plants to uptake PFAS, soybean seeds may need to be quantified for PFAS concentrations before their use in agricultural fields.

• 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.

• 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.

• Are resource recovery insects safe for feed and food? A screening approach for bioaccumulative trace organic contaminants

  Science

  1 Jun 2022 | Sci. Total Environ.

  Four PFAS (PFBA, PFOA, PFBS, and PFOS) did not bioaccumulate in larvae, and non-target analysis revealed emerging PFAS present in larvae and almond hulls.

• Assessment of Bioactive Surfactant Levels in Selected Cereal Products

  Science

  30 May 2022 | Applied Sciences

  The most frequently detected compound was PFOA, which was quantified in 65.2% of samples, while PFBA was present in the majority of cereal based products.
