PFAS exposures in childhood are negatively associated with overall bone mass density, with the strongest association seen for PFNA amongst 5-year-olds.
Biota-Sediment Accumulation Factors (BSAFs) for Per- and Polyfluorinated Substances (PFAS)
18 Nov 2022 | Environ Toxicol Chem
A summary of biota-sediment accumulation factors is given for many PFAS, and the largest research gap identified is understanding the effects of concentration and mixtures upon bioaccumulation from sediments.

NJDEP identified the need for many revisions in both the factual information and the conclusions about health effects, treatment removal, and other topics discussed in the draft WHO document.
Nontargeted screening reveals fluorotelomer ethoxylates in indoor dust and industrial wastewater.
15 Nov 2022 | Environ. Int.
FTEOs were detected in 60% of indoor dust samples and c. 40% of industrial effluent samples, with the highest concentrations in healthcare facility dust and the effluents from electroplating facilities, manufacturers of cosmetics and personal care products, and linen cleaning services for healthcare and work uniforms.
Associations of per- and polyfluoroalkyl substances (PFAS) and their mixture with oxidative stress biomarkers during pregnancy
14 Nov 2022 | Environ Intern
PFOS was associated with elevated oxidative stress levels during pregnancy, which may affect fetal development.
Paints: A Source of Volatile PFAS in Air - Potential Implications for Inhalation Exposure
11 Nov 2022 | Environ Sci Technol
Common paints were found to contain 6:2 FTOH and 6:2 diPAP that accounted for up to 17% of total fluorine, with 40% of FTOH mass lost upon drying. Exposure estimates suggest that PFAS exposure while painting could exceed recommended reference doses for children and adults.
Apparent Half-Lives of Chlorinated-Perfluorooctane Sulfonate and Perfluorooctane Sulfonate Isomers in Aviation Firefighters
11 Nov 2022 | Environ Sci Technol
The average half-life of Cl-PFOS among firefighters with previous exposure to fluorinated AFFF was 5.0 years, although other forms of PFOS had half-lives ranging from 4-11.5 years.
Per- and Poly-Fluoroalkyl Substances in Runoff and Leaching from AFFF-Contaminated Soils: a Rainfall Simulation Study
10 Nov 2022 | Environ Sci Technol
PFAS concentrations in AFFF-contaminated soils declined significantly after the first rainfall event, but desorption and transport in both runoff and leachates persisted over several rainfall events.
[Public Comments] International Society for Environmental Epidemiology Comments on Draft World Health Organization Drinking Water Quality Guidelines for PFOA and PFOS
10 Nov 2022 | ISEE Website
The ISEE, a leading scientific association in environmental epidemiology that impacts research, training, and policy worldwide, identified that the provisional WHO guidelines neither protect human health nor include the latest scientific literature.
Legacy and emerging airborne per- and polyfluoroalkyl substances (PFAS) collected on PM2.5 filters in close proximity to a fluoropolymer manufacturing facility
9 Nov 2022 | Environ Sci Process Impacts
Twelve emerging and ten legacy PFAS compounds were detected in aerosol samples around a fluoropolymer manufacturing facility at concentrations higher than at regional background sites, suggesting the manufacturing facility as the local source for these compounds.
