Comparison of untargeted and targeted perfluoroalkyl acids measured in adolescent girls
25 Jan 2022 | Chemosphere
Environmental exposure measures from untargeted assays are comparable with targeted assays, and can serve as reliable inputs into statistical analysis for discovery and for determining their biological impacts.
Industrial byproducts for the soil stabilization of trace elements and per-and polyfluorinated alkyl substances (PFASs)
25 Jan 2022 | Sci Total Environ
Industrial byproducts can provide sustainable and cost-effective materials for soil remediation of PFAS, but the sorbent must be tailored to the type of soil and type of contamination.

[Working Paper] Nordic enforcement project on PFOS and PFOA in chemical products and articles
25 Jan 2022 | Norden
The Nordic Enforcement Group found that 10% of chemical products and articles were non-compliant with restrictions on PFOA and PFOS, with more products containing other PFAS that are not yet restricted.
Background release and potential point sources of per-and polyfluoroalkyl substances to municipal wastewater treatment plants across Australia
24 Jan 2022 | Chemosphere
About 60% of PFAS in Australian wastewater treatment plant influent was due to background release (at a rate of 8.1-24 μg/day/person) with the remaining ~40% due to point sources including industrial activities.
Perfluorooctanoic acid (PFOA)-induced alterations of biomolecules in the wetland plant Alisma orientale
20 Jan 2022 | Sci Total Environ
FTIR was used to demonstrate the adverse effects of PFOA on plant growth and water uptake.
A worldwide evaluation of trophic magnification of per- and polyfluoroalkyl substances in aquatic ecosystems
17 Jan 2022 | Integr Environ Assess Manag
This review discusses the variability of environmental characteristics driving PFAS biomagnification in natural ecosystems and highlights the different approaches used by various studies, which can make comparisons among studies challenging.
Anthropogenic Drivers of Variation in Concentrations of Perfluoroalkyl Substances in Otters () from England and Wales.
17 Jan 2022 | Environ Sci Technol
PFAS concentrations in otters were positively associated with effluent from wastewater treatment plants, agriculture, and a fluoropolymer production facility.
Bioaccumulation and impact of maternal PFAS offloading on egg biochemistry from wild-caught freshwater turtles (Emydura macquarii macquarii)
17 Jan 2022 | Sci Total Environ
PFAS from the mothers were found to bioaccumulate in egg yolks which contained up to 97% of bioaccumulated PFAS, and impacted eggs had changes in metabolite, lipid, and protein levels.
Demographic, life-style and physiological determinants of serum per- and polyfluoroalkyl substance (PFAS) concentrations in a national cross-sectional survey of Swedish adolescents
17 Jan 2022 | Environ Res
Legacy PFAS were found at elevated levels throughout Swedish adolescents in addition to the novel 9Cl-PF3ONS in 5% of those tested, and females had lower serum PFAS concentration than males.
Mass-Labeled Fluorotelomer Alcohol Fragmentation Gives "False Positive" for Nonlabeled Fluorotelomer Alcohols with Implications for Consumer Product Analysis
17 Jan 2022 | J Am Soc Mass Spectrom
Deuterium or hydrogen abstraction of some standards was found to produce a false positive when testing for FTOHs by chemical ionization mass spectrometry.
Exposure to perfluorooctanoic acid leads to promotion of pancreatic cancer
16 Jan 2022 | Carcinogenesis
PFOA was found to potentially promote pancreatic cancer progression in a mice model.
Exposure of Preconception Couples to Legacy and Emerging Per- and Polyfluoroalkyl Substances: Variations Within and Between Couples
16 Jan 2022 | Environ Sci Technol
Individual PFAS were generally correlated within couples though men often exhibited higher plasma concentrations, and PFAS exposure between different couples depended on annual household income, dwelling floor type, drinking water source, and living near farmlands.
Characterization of Per- and Polyfluorinated Alkyl Substances Present in Commercial Anti-fog Products and Their Adipogenic Activity
10 Jan 2022 | Environ Sci Technol
High concentrations of PFAS were detected in all measured anti-fog products, with FTEOs found to be a significant contributor to the adipogenic activity exhibited by the anti-fog sprays.
Prevalence and Implications of Per- and Polyfluoroalkyl Substances (PFAS) in Settled Dust
10 Jan 2022 | Curr Environ Health Rep
This review emphasizes the prevalence of PFAS in indoor dust - especially daycares and workplaces - with sources of PFAS including building materials and furnishings and consumer products.
