Spatial Variations in Per-and Polyfluoroalkyl Substance Concentrations in Pooled Sera from Inland, Coastal, and Island Populations
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.
Sources and Seasonal Variations of Per- and Polyfluoroalkyl Substances (PFAS) in Surface Snow in the Arctic
26 Nov 2024 | Environ Sci Technol
PFAS in remote Arctic snow formed during long-range atmospheric processes were found to positively correlate with the amount of sunlight, suggesting seasonal influences on their formation and deposition. This study also provided the first evidence for the possible atmospheric formation of PFOS and GenX.
Associations between per-and polyfluoroalkyl substances and menstrual cycle regularity in reproductive-aged female: a cross-sectional study
25 Nov 2024 | Emerging Contaminants
Exposure to branched PFOS and PFNA was significantly associated with irregular and long menstrual cycles, with these effects being more pronounced among women with low physical activity, suggesting potential reproductive risks linked to PFAS exposure and the influence of lifestyle factors.
Release of Volatile Per- and Polyfluoroalkyl Substances from Plant Fiber-Based Food Packaging and Municipal Solid Waste to Gas under Simulated Landfill Conditions.
19 Nov 2024 | Environ Sci Technol
High-fluorine food packaging released 62–800 ng PFAS per gram into the air, dominated by 6:2 fluorotelomer alcohol, with early decomposition stages accounting for most of the emissions.
The Exposure Status of Environmental Chemicals in South Korea: The Korean National Environmental Health Survey 2018-2020
19 Nov 2024 | Toxics
Among Korean adolescents, PFAS such as PFOA, PFOS, PFNA, and PFDeA were correlated with higher cholesterol levels, including LDL-C and total cholesterol. Adolescents highly exposed to both PFAS and heavy metals like mercury also had significantly higher lipid profiles.
Fate of ‘forever chemicals’ in the global cryosphere
18 Nov 2024 | Earth-Science Reviews
This review highlights the spread, accumulation, and release of PFAS in the cryosphere, including impacts from global warming, which poses significant ecological risks and harms biodiversity.
Study of Endocrine-Disrupting Chemicals in Infant Formulas and Baby Bottles: Data from the European LIFE-MILCH PROJECT
18 Nov 2024 | Molecules
Infant formulas and baby bottles were found to contain endocrine-disrupting chemicals, including PFAS such as PFOA, PFBS, PFDA, PFHxA, and PFHpA, along with phthalates, bisphenols, metals, and more, highlighting the need for stricter monitoring and public health interventions to protect infants.
Association between Exposure to Per- and Polyfluoroalkyl Substances and Missed Miscarriage: A Hospital-Based Case-Control Study in Shanghai, China
16 Nov 2024 | Environ Toxicol Pharmacol
Plasma concentrations of 13 PFAS, including PFOA, L-PFOS, and 6:2 Cl-PFESA were significantly associated with increased risk of miscarriage in women, with PFOA showing the strongest association, highlighting the reproductive risks linked to PFAS exposure.
Examining Disparities in PFAS Plasma Concentrations: Impact of Drinking Water Contamination, Food Access, Proximity to Industrial Facilities and Superfund Sites
14 Nov 2024 | Environ Res.
PFAS plasma levels were higher in individuals living near Superfund sites or PFAS-polluting facilities and in areas with low food access, with drinking water contamination contributing significantly to elevated plasma PFOS, PFOA, and PFHxS levels, highlighting disparities in PFAS exposure driven by industrial and socioeconomic factors.
Environmental Occurrence and Biotic Concentrations of Ultrashort-Chain Perfluoroalkyl Acids: Overlooked Global Organofluorine Contaminants
13 Nov 2024 | Environ Sci Technol
Ultrashort-chain perfluoroalkyl acids (PFAAs), including TFA, are widely present in the environment and living organisms, with rising concentrations over the past three decades, often exceeding those of longer-chain PFAAs in various ecosystems.
A Pilot Study of Bis-perfluoroalkyl Sulfonimides in Dust from E-waste and Urban Regions
12 Nov 2024 | Environ. Sci. Technol. Lett.
Dust samples from e-waste recycling sites showed significantly higher levels of bis-FMeSI (median 12 ng/g) compared to surrounding and urban areas, indicating e-waste recycling as a major source of environmental release for this emerging PFAS, which poses potential ecological and human health risks.
Permeation of Per-and Polyfluoroalkyl Substances (PFAS)-Laden Leachate in Landfills as an Outcome of Puncture Failures of High-Density Polyethylene Geomembranes
12 Nov 2024 | Environmental Pollution
Puncture failures in high-density polyethylene landfill liners increase the permeation of hazardous PFAS-laden leachate. Short-chain PFAS, due to their surfactant properties, significantly enhanced permeation rates, highlighting concerns over environmental contamination if proper landfill protections are not maintained.
