PFAS-Free Energy Storage: Investigating Alternatives for Lithium-Ion Batteries

4 Dec 2024 | Environ. Sci. Technol.

Alternatives to PFAS in lithium-ion batteries include bio-based polymers, fluorine-free ionic liquids, and siloxane-based compounds, all designed to provide similar thermal and chemical stability without the environmental persistence and toxicity of PFAS.

Per- and polyfluoroalkyl substances, apolipoproteins and the risk of coronary heart disease in US men and women

3 Dec 2024 | Environ Health

Elevated concentrations of PFOS in the blood were strongly associated with an increased risk of coronary heart disease, with the risk more than tripling for each unit increase in PFOS levels.

Residential Garden Produce Harvested Near a Fluorochemical Manufacturer in North Carolina Can Be An Important Fluoroether Exposure Pathway

2 Dec 2024 | J. Agric. Food Chem.

Residential garden produce grown near a fluorochemical manufacturing plant in North Carolina was found to contain significant levels of PFAS, predominantly low-molecular-weight PFEAs such as PMPA, PFO2HxA, PFMOAA, and GenX, with water-rich produce showing the highest contamination, posing potential dietary exposure risks for local communities.

Concentrations and exposure risks of per- and polyfluoroalkyl substances in human milk from Southern China during the first 400 days of lactation

2 Dec 2024 | Ecotoxicol Environ Saf

Infants consuming breastmilk during their first 400 days face significant health risks from PFAS exposure, especially in the first 45 days, making it crucial to minimize dietary and environmental PFAS exposure in lactating women to reduce concentrations in human milk.

Comprehensive characterization of European house dust contaminants: Concentrations and profiles, geographical variability, and implications for chemical regulation and health risk

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​.

Impact of local food consumption on exposure to perfluorooctanoic acid and perfluorooctane sulfonate in a contaminated community in North-Eastern Italy

30 Nov 2024 | Epidemiol Prev

Consuming locally-grown foods in PFAS-contaminated areas can significantly increase exposure to PFOA and PFOS, leading to prolonged elevated blood levels, with affected individuals taking about three more years to reduce their concentrations to levels below a clinically significant threshold level.

Exploring Perfluoroalkyl Substances Contamination in Human Breast Milk: First Ghanaian Study

29 Nov 2024 | Chemosphere

Human breast milk in Ghana contains detectable levels of PFAS, including PFHxA, PFHpA, PFOA, and PFOS, highlighting potential exposure risks to infants through breastfeeding, especially for PFOS and PFOA.

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.
