Prenatal exposure to per- and polyfluoroalkyl substances, fetoplacental hemodynamics, and fetal growth
20 Oct 2024 | Environ Int
Legacy PFAS exposure during pregnancy may be linked to reduced fetal growth, but the effects of next-generation PFAS and PFAS mixtures are less clear, with further research needed to understand their impact on fetoplacental blood flow.
Fluorotelomer Alcohol (FTOH) Emission Rates from New and Old Rain Jackets to Air Determined by Iodide High-Resolution Chemical Ionization Mass Spectrometry
16 Oct 2024 | Indoor Environments
Older rain jackets released high amounts of fluorotelomer alcohols (FTOHs) into indoor air, raising concerns about indoor PFAS exposure through clothing, and even newer “PFAS-free” jackets emitted small amounts of PFAS, likely through contamination during transport or storage.
Comprehensive analysis of PFAS presence from environment to plate
16 Oct 2024 | npj Science of Food volume
Fish, seafood, and biota show the highest PFAS concentrations due to environmental contamination and bioaccumulation, along along with frequent detections in surface water, raising concerns about long-term ecological and human health effects.
Removal of Per-and Polyfluoroalkyl Substances (PFAS) in Fixed Bed Anion Exchange Reactors: Factors Determining PFAS Uptake Capacity and Models Predicting PFAS Breakthrough
13 Oct 2024 | Water Research
Anion exchange processes can effectively remove PFAS from water, but their efficacy is influenced by PFAS structure and other chemicals dissolved in the water. New models were developed to predict PFAS removal based on these factors in water treatment.
Partitioning of Neutral PFAS in Homes and Release to the Outdoor Environment: Results from the IPA Campaign
10 Oct 2024 | Indoor Environments
A study measuring neutral PFAS in 11 North Carolina homes found that (fluorotelomer alcohols) FTOHs dominate in dust, HAC filter, and dryer lint samples, while perfluorooctane sulfonamidoethanols (FOSEs) are most prevalent in airborne particles.
The potential mediating role of the gut microbiome and metabolites in the association between PFAS and kidney function in young adults: A proof-of-concept study
10 Oct 2024 | Sci Total Environ
Researchers reported for the first time that changes to the gut microbiome may explain the association between high PFAS exposure and impaired kidney function.
Uptake of PFAS into forages grown in contaminated soil, a key aspect of the soil-to-livestock exposure pathway
8 Oct 2024 | J. Agric. Food Chem.
PFAS uptake from contaminated soil into different plants was measured in order to better model soil-to-livestock exposure scenarios, which is essential to guide farm management to reduce PFAS exposure in livestock and humans.
Serum per- and polyfluoroalkyl substance (PFAS) levels and health-related biomarkers in a pilot study of skiers in New England
8 Oct 2024 | Environ Res
Ski coaches were found to have elevated levels of PFAS through ski wax exposure as well as higher cholesterol levels, suggesting a need for interventions to reduce PFAS in ski waxes and limit environmental release.
Skin Permeability of Perfluorocarboxylic Acids Using Flow-Through Diffusion on Porcine Skin
7 Oct 2024 | Toxics
Using porcine skin, PFBA showed higher skin permeability compared to other PFAS, and although overall absorption was low, these chemicals can accumulate in the skin, potentially acting as a long-term reservoir. Using porcine skin, PFBA showed higher skin permeability compared to other PFAS, and although overall absorption was low, these chemicals can accumulate in the skin, potentially acting as a long-term reservoir.
County-level associations between drinking water PFAS contamination and COVID-19 mortality in the United States
6 Oct 2024 | Nature
PFAS contamination in U.S. drinking water systems was associated with higher pre-vaccination COVID-19 mortality rates, reinforcing the need for ongoing monitoring and regulations to improve water quality and possibly reduce risks of severe infectious disease outcomes.
Indoor air concentrations of PM2.5 quartz fiber filter-collected ionic PFAS and emissions to outdoor air: findings from the IPA campaign
1 Oct 2024 | Environ. Sci.: Processes Impacts.
PFAS levels in residential indoor particulate matter were more than three times higher than nearby outdoor concentrations and an order of magnitude higher than remote background concentrations, suggesting that emissions from homes could be important contributors to PFBA, PFOA, and PFOS emissions in populated areas far from major point sources.
Determination of per- and polyfluoroalkyl substances (PFAS) in six different fish species from Swiss lakes
1 Oct 2024 | Anal Bioanal Chem
Significant PFAS contamination was found in freshwater fish from Swiss lakes, particularly in European Perch, with PFOS and PFHxS levels often exceeding EU safety limits, highlighting the need for ongoing monitoring and regulation to protect aquatic ecosystems and human health through decreased fish consumption.
Kidney function mediates the association of per- and poly-fluoroalkyl substances (PFAS) and heavy metals with hepatic fibrosis risk
30 Sep 2024 | Environ Res
Exposure to heavy metals and PFAS increases the risk of liver damage, with declining kidney function playing a major role in worsening this effect, emphasizing the need to consider kidney health in managing liver disease risks.
Tissue distribution and temporal and spatial assessment of per- and polyfluoroalkyl substances (PFAS) in smallmouth bass (Micropterus dolomieu) in the mid-Atlantic United States
30 Sep 2024 | Environ Sci Pollut Res Int
PFAS contamination was found in smallmouth bass from various river systems in the mid-Atlantic U.S., with higher concentrations linked to areas with more developed land and PFAS facilities like military installations and airports, emphasizing the effects of land use and point sources on fish contamination.
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.
