Fluoropolymer sorbent for efficient and selective capturing of per- and polyfluorinated compounds
27 Sep 2024 | Nat Commun
A newly developed reusable polymeric sorbent, PFPE-IEX+, has been shown to efficiently capture over 98% of multiple PFAS contaminants from water sources, including drinking water and landfill leachate, with high sorption capacity and the potential for repeated regeneration.
Forecasting and Hindcasting PFAS Concentrations in Groundwater Discharging to Streams near a PFAS Production Facility
25 Sep 2024 | Environ. Sci. Technol.
PFAS was detected in groundwater that is nearly half a century old near North Carolina's Cape Fear River, and is expected to persist above safe levels in discharge to streams until at least 2050-2060, highlighting the long-term environmental impact of these chemicals.
Prenatal exposure to PFAS and the association with neurobehavioral and social development during childhood
25 Sep 2024 | Int J Hyg Environ Health
Prenatal exposure to PFAS shows mixed effects on children's neurobehavioral and social development markers like behavioral issues and anxiety, but strong associations were not found in this population with low PFAS exposure and depended on the children’s sex, type of PFAS, and developmental outcome.
A 20-Year study reveal decrease in per- and polyfluoroalkyl substances (PFAS) in a pelagic seabird from the Western Mediterranean
24 Sep 2024 | Environ Pollut
PFAS levels in the livers of a Mediterranean seabird have decreased by 77%, though persistent detection of these chemicals, especially PFOS and its substitutes, highlights the ongoing need for stronger global efforts to reduce environmental PFAS pollution.
Antibody response to SARS-CoV-2 mRNA vaccination in Danish adults exposed to per-and polyfluorinated substances: The ENFORCE study
24 Sep 2024 | Environ Res
No clear association was found between PFAS exposure and immune responses to initial COVID-19 vaccines, but higher PFAS exposure was weakly associated with a diminished immune response to booster vaccines.
Per-and polyfluoroalkyl substances and disrupted sleep: mediating roles of proteins
23 Sep 2024 | Environmental Advances
Exposure to certain PFAS chemicals has been associated with shorter sleep duration and increased sleep disturbances in young adults, potentially due to disruptions in metabolic and immune system functions.
Per-and polyfluoroalkyl substances (PFAS) in floor dust from different indoor environments in Australia: Levels, variation, and human exposure risks
19 Sep 2024 | Chemosphere
Human exposure to PFAS through dust varies across indoor environments, with higher concentrations found in offices compared to houses and public transport vehicles.
Multimedia and Full-Life-Cycle Monitoring Discloses the Dynamic Accumulation Rules of PFAS and Underestimated Foliar Uptake in Wheat near a Fluorochemical Industrial Park
18 Sep 2024 | Environ. Sci. Technol.
PFAS contamination near a major industrial park in China, particularly from airborne deposition, has led to significant accumulation in soil and wheat, with spray irrigation increasing PFAS absorption in wheat compared to flood irrigation. Local residents have high exposure risks through wheat consumption and air inhalation.
Storms mobilize organophosphate esters, bisphenols, PFASs, and vehicle-derived contaminants to San Francisco Bay watersheds
18 Sep 2024 | Environ Sci Process Impacts
Stormwater runoff in San Francisco Bay watersheds contains several PFAS and flame retardants, with some concentrations exceeding safe levels, posing significant toxicity risks to aquatic ecosystems.
Levels and trends of persistent organic pollutants in human populations living in the Arctic
17 Sep 2024 | Int J Circumpolar Health
Long-chain PFAS, such as PFNA and PFDA, are increasing in Arctic populations, especially in Greenland and Nunavik, due to their bioaccumulation in marine wildlife, posing significant health risks.
Per-and polyfluoroalkyl substances (PFAS) in drinking water in Southeast Los Angeles: Industrial legacy and environmental justice
16 Sep 2024 | Sci. Total Environ.
PFAS were detected in 30% of tap water samples from California, with the highest concentrations found in low-income, predominantly Latino communities in heavily industrialized areas of Southeast Los Angeles, highlighting the need for improved water testing and regulations to protect vulnerable populations.
Exploring the variability of PFAS in urban sewage: a comparison of emissions in commercial versus municipal urban areas
13 Sep 2024 | Environ Sci Process Impacts
PFOS and 6:2 FTS concentrations were significantly higher in wastewater from commercial areas, with median loads exceeding 0.9 μg per person per day, while municipal areas had lower levels, indicating that commercial activities are a major source of PFAS emissions in urban wastewater.
Development, validation, and clinical assessment of a liquid chromatography-tandem mass spectrometry serum assay for per- and polyfluoroalkyl substances (PFAS) recommended by the National Academies of Science, Engineering, and Medicine (NASEM)
13 Sep 2024 | Anal Bioanal Chem
In 2022, new guidelines recommended measuring nine PFAS compounds in blood, and in this study, 82.2% of samples had concentrations between 2 and 20 ng/mL, with a lower median PFAS level than previous national surveys, indicating a potential decrease in exposure or differences in population exposure patterns over time.
Maternal Exposure to Per- and Polyfluoroalkyl Substances and Offspring Chromosomal Abnormalities: The Japan Environment and Children's Study
11 Sep 2024 | Environ Health Perspect
Maternal exposure to certain PFAS chemicals, particularly PFOS, may be associated with an increased risk of chromosomal abnormalities in offspring, though further research is needed due to potential selection bias.
