Disclosure of Conflict of Interest Regarding the paper “Per- and Poly-fluoroalkyl Substances (PFAS) Exposure and Risk of Kidney

16 Dec 2024 | Medicina del Lavoro

A letter to the editor raising a conflict of interest regarding a co-author of a previously published review paper on the associations between PFAS exposure and possible cancer risk.

Per-and polyfluoroalkyl substances in paired serum and breastmilk samples among pregnant farmworkers in Thailand

16 Dec 2024 | Int. J. Hyg. Environ. Health.

PFOS and PFNA were the most commonly detected PFAS in breastmilk from Thai farmworkers, with lactational transfer efficiencies up to 14.7%, highlighting a significant route of postnatal exposure for infants.

Early-life exposure to PCBs and PFAS exerts negative effects on the developing Central Nervous System

16 Dec 2024 | J. Hazard. Mater.

Early-life exposure to PCBs and PFAS disrupts brain development by impairing the blood-brain barrier, causing oxidative stress, and altering neurodevelopmental processes, potentially leading to cognitive deficits, neuropsychiatric disorders, and endocrine disruption.

[EDITORIAL] Fluoropolymers and nanomaterials, the invisible hazards of cell phone and computer touchscreens

11 Dec 2024 | Environ Chem Lett

Nanomaterials and fluoropolymers in touchscreen coatings, designed to repel smudges, pose hidden risks of toxicity and environmental harm as they degrade and transfer to users' skin, especially affecting children and frequent users.

Occurrence, Transport, and Full-Scale Adsorptive Removal of PFAS in Electroplating Parks in China

11 Dec 2024 | Environ. Sci. Technol.

Granular activated carbon and hydrophobic anion exchange resin were found to effectively remove up to 98.2% of PFAS from electroplating wastewater in China, reducing annual PFAS discharge by 5030–8000 kg. Anion exchange resin showed higher efficiency but lower selectivity for certain PFAS.

Individual and joint associations of exposure to per- and polyfluoroalkyl substances with children's mitochondrial DNA copy number, and modified by estimated glomerular filtration rate

10 Dec 2024 | Environ Res

Legacy and emerging PFAS, especially PFOA, were associated with lower levels of mitochondrial DNA in children, with more pronounced associations seen in those with weaker kidney function and older age, highlighting the potential health risks of PFAS exposure in early life.

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.
