Assessing potential human health and ecological implications of PFAS from leave-in dental products
Science
3 Jan 2024 | Toxicol Ind Health
PFBA and PFOS were found in low levels in night guards with no detection in whitening trays, suggesting these dental products are unlikely to pose health concerns or contribute significantly to environmental PFAS exposure compared to exposure from food and water.

Understanding the effects of per- and polyfluoroalkyl substances on early skin development: Role of ciliogenesis inhibition and altered microtubule dynamics
Science
30 Dec 2023 | Sci Total Environ
Exposure to PFOS may disrupt early skin development by altering cell morphology, gene expression, and crucial signaling pathways, suggesting a potential link between PFAS exposure and congenital skin diseases during embryonic development.

Environmental distribution of per-and polyfluoroalkyl substances (PFAS) on Svalbard: Local sources and long-range transport to the Arctic
Science
23 Oct 2023 | Chemosphere
PFAS were found in various environmental samples along the west coast of the Norwegian Arctic with significant contributions from wastewater and a firefighting training site. Melting snow and ice during Arctic spring may also become an increasingly important PFAS source with climate warming.

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.
