Foreign-born individuals tend to have higher levels of serum PFAS the longer they stay in the United States.
Leveraging Systematic Reviews to Explore Disease Burden and Costs of Per and Polyfluoroalkyl Substance
1 Aug 2022 | Exposure and Health
This study identified at least $5.5 billion in annual disease burden and social costs due to long-chain PFAS exposure, demonstrating that regulatory actions to limit PFAS use and remediate contaminated water may produce substantial economic benefits.
Uptake of individual and mixed per- and polyfluoroalkyl substances (PFAS) by soybean and their effects on functional genes related to nitrification, denitrification, and nitrogen fixation
29 Jul 2022 | Sci. Total Environ.
The synergistic effect of a PFAS mixture increased the uptake of individual PFAS in soybeans, which led to changes in genes involved in the nitrogen cycle.
Per-and polyfluoroalkyl substances in the atmosphere of waste management infrastructures: Uncovering secondary fluorotelomer alcohols, particle size distribution, and human inhalation exposure
29 Jul 2022 | Environ. Int.
PFAS were prevalent in the air and in particulate matter near landfills and wastewater treatment plants, and modeling demonstrated that fine and ultrafine particles may carry PFAS into the lung alveoli.
Per- and polyfluoroalkyl substances (PFASs) in consumable species and food products
28 Jul 2022 | J Food Sci Technol
This review found that legacy PFAS remain in high abundance and that proximity to factories and fluorochemical industries results in potentially hazardous levels of PFAS contamination in all types of food products.
Increasing Accumulation of Perfluorocarboxylate Contaminants Revealed in an Antarctic Firn Core (1958–2017)
26 Jul 2022 | ES&T
PFCA and PFBA accumulation in snow increased, and although chemical fluxes of PFOA and PFNA peaked in 2009–2013, there is little evidence of a decline in PFAAs despite supposed recent global curtailments in their production.
Are cosmetics a significant source of PFAS in Europe? product inventories, chemical characterization and emission estimates
21 Jul 2022 | Environ Sci Process Impacts
Annual European-wide cosmetic-related total fluorine and extractable organic fluorine emissions to wastewater and solid waste ranged from 17-38,000 kg F per year and 37-5100 kg F per year, respectively, representing a high emission source that is still lower than emissions from washing PFAS-coated textiles.
Adsorption of per-and polyfluoroalkyl substances (PFAS) to containers
21 Jul 2022 | J. Hazard. Mater.
Containers used to hold PFAS mixtures adsorbed the chemicals at different rates based on PFAS chemistry, container hydrophobicity, temperature, and container manufacturer, with the general trend of PFAS adsorption as polypropylene > HDPE > PET > glass > polystyrene.
Occurrence and Fate of Ultrashort-Chain and Other Per-and Polyfluoroalkyl Substances (PFAS) in Wastewater Treatment Plants
19 Jul 2022 | ACS ES&T Water
The transformation of precursors into shorter chain PFAAs by biological treatment and the partitioning of longer chain PFAS into sludge streams are key factors determining the fate of PFAS in wastewater treatment plants.
Next Generation Per-and Poly-Fluoroalkyl Substances: Status and Trends, Aquatic Toxicity, and Risk Assessment
19 Jul 2022 | EEH
Future uses of PFAS remain uncertain in the face of governmental regulations and production bans, but replacement PFAS will continue to emerge on the world market and in the environment, raising concerns about their general lack of information on mechanisms and toxic potencies.
[Opinion] Speaking the Same Language: The Need for Accurate and Consistent Reporting of Novel Per-and Polyfluoroalkyl Substances
18 Jul 2022 | ES&T
Recommendations presented in this viewpoint are encouraged for all PFAS researchers performing non-targeted analysis to prevent miscommunication and misidentification of PFAS compounds.
Association of increased risk of cardiovascular diseases with higher levels of perfluoroalkylated substances in the serum of adults
18 Jul 2022 | Environ Sci Pollut Res Int
A significant relationship between higher serum PFAS concentrations and an increased risk of cardiovascular disease was observed, mainly in males.
GenX Induces Fibroinflammatory Gene Expression in Primary Human Hepatocytes
15 Jul 2022 | Toxicology
GenX can interfere with metabolic pathways at lower doses and induce abnormal inflammation in human liver cells at higher doses.
Global distributions, source-type dependencies, and concentration ranges of per-and polyfluoroalkyl substances in groundwater
11 Jul 2022 | Sci Total Environ
This meta-analysis found that PFAS are detected in all media in all regions tested, which is a reflection of the large scale-use of PFAS, their persistence, and long-range transport.
Suspect screening and nontargeted analysis of per- and polyfluoroalkyl substances in representative fluorocarbon surfactants, aqueous film-forming foams, and impacted water in China
9 Jul 2022 | Environ. Int.
69 PFAS were identified in Chinese fluorosurfactants such as those used in aqueous film-forming foams, and high concentrations of neutral PFAS were found in polymer-based products.
