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.

Per- and polyfluoroalkyl substances (PFAS) measured in seafood from a cross-section of retail stores in the United States
Science
13 Jul 2023 | J Hazard Mater
PFAS levels in several grocery store seafood samples were found to exceed safe levels, and PFBS from food storage bags contaminated the fish, potentially leading to a substantial impact on human exposure.

Diffusion and partitioning of different PFAS compounds through thermoplastic polyurethane and three different PVC-EIA liners
Science
26 May 2023 | Sci Total Environ
PFAS was found to diffuse through certain membranes used in landfills, potentially leading to groundwater contamination.

Centurial Persistence of Forever Chemicals at Military Fire Training Sites
Science
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.

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.

Occurrence, partitioning and transport of perfluoroalkyl acids in gas and particles from the southeast coastal and mountainous areas of China
Science
5 Dec 2022 | Environ Sci Pollut Res Int.
The longer the fluorinated carbon chain length of the PFAA, the more the PFAA tended to exist in the particulate phase, and PFAS in China can be widely spread through the atmosphere due to winter monsoon winds.

Maternal exposure to perfluorobutane sulfonate (PFBS) during pregnancy: evidence of adverse maternal and fetoplacental effects in New Zealand White (NZW) rabbits
Science
1 Dec 2022 | Toxicol Sci
PFBS exposure during gestation may lead to renal injury, hypertension in the mother, and decreased fetal growth.

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.

American Chemistry Council Uses Disinformation to Target PFAS Safeguards
News
8 Aug 2022 | The Equation
In its statement about the petition, the ACC claimed to support the development of drinking water standards for the PFAS chemicals PFOA PFOS, PFBS, and GenX. But it speciously charged that EPA was failing to ensure “the scientific integrity of its process.”
