Oregon moves to regulate harmful ‘forever chemicals’
Policy
2 Apr 2025
Oregon’s list of regulated hazardous substances is getting its first update in nearly two decades with the addition of six “forever chemicals” known to harm human health.

Leaching profile of per-and polyfluoroalkyl substances from selected e-waste components and potential exposure pathways from discarded components
Science
17 Mar 2025 | J Hazard Mater
Discarded electronics like cables, keyboards, monitors, and circuit boards can release harmful PFAS—especially PFBA, PFHxA, PFOA, and PFOS—into the environment through leaching, highlighting e-waste as a significant but underrecognized source of long-term contamination and exposure risks.

Comprehensive characterization of European house dust contaminants: Concentrations and profiles, geographical variability, and implications for chemical regulation and health risk
Science
2 Dec 2024 | Sci Total Environ
Analysis of European house dust revealed over 1,200 contaminants, including persistent pollutants like DEHP, PFOA, PFOS, PFBA, and PFBS, with geographic trends showing higher levels of certain chemicals in Southern Europe, underscoring the need for stricter regulation and improved risk assessment.

Spatial Variations in Per-and Polyfluoroalkyl Substance Concentrations in Pooled Sera from Inland, Coastal, and Island Populations
Science
28 Nov 2024 | Environmental Research
PFAS levels were found to be higher in coastal and island populations compared to inland areas, likely due to seafood consumption and other location-specific exposure routes.

It’s raining PFAS in South Florida: Occurrence of per-and polyfluoroalkyl substances (PFAS) in wet atmospheric deposition from Miami-Dade, South Florida
Science
9 Sep 2024 | Atmos. Pollut. Res.
Rainwater in Florida contained significant levels of PFAS chemicals, including PFBA, PFNA, PFOS, and PFOA, particularly during the dry season, and analysis suggested both local and distant sources of contamination.

The unique distribution pattern of PFAS in landfill organics
Science
3 Sep 2024 | J. Hazard. Mater.
PFAS chemicals from decomposing landfill waste predominantly accumulate at middle depths within a landfill, with a strong correlation between total PFAS, total carbon, and dissolved organic matter in landfill organics.

Preferential Partitioning of Per-and Polyfluoroalkyl Substances in Freshwater Ice
Science
13 Aug 2024 | Environ. Sci. Technol.
PFAS are typically excluded from ice as freshwater lakes freeze, but some PFAS and dissolved organic carbon are preferentially concentrated in the ice, affecting their distribution and potential release into the environment when the ice melts.

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.

Chemical crisis: The unseen toxic threat contaminating wildlife worldwide
News
28 Oct 2023 | The Hill
An unseen but growing chemical contamination crisis is threatening wildlife across all seven continents, exacerbating a host of environmental threats they’re already facing.

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.

Per- and Polyfluoroalkyl Substances (PFAS) in PubChem: 7 Million and Growing
Science
23 Oct 2023 | Environ. Sci. Technol.
The Organisation for Economic Co-operation and Development's 2021 revision of the PFAS definition has led to the inclusion of over 7 million PFAS compounds in PubChem.

Per- and polyfluoroalkyl substances in umbilical cord serum and body mass index trajectories from birth to age 10 years: Findings from a longitudinal birth cohort (SMBCS)
Science
28 Sep 2023 | Environ Int
Certain PFAS such as, PFUnDA and PFDoDA, in umbilical cord serum were associated with higher BMI from birth to age 10 years.

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.
