A review of PFAS fingerprints in fish from Norwegian freshwater bodies subject to different source inputs
1 Feb 2022 | Environ Sci Process Impacts
Source tracking of PFAS exposure was most successful using fish livers, with fingerprints from AFFF dominated by PFOS and PFSA and fingerprints from paper production dominated by PFCAs and high ∑PFAS and PFOS.
Serum levels of perfluoroalkyl substances (PFAS) and body composition - A cross-sectional study in a middle-aged population
1 Feb 2022 | Environ Res
PFOA, PFNA, and PFDA were inversely related to fat mass measurements in women but not men, while PFOS and PFHxS had no consistent associations with body composition.

PFAS Molecules: A Major Concern for the Human Health and the Environment
25 Jan 2022 | Toxics
This review summarizes the current knowledge on PFAS chemistry uses, occurrence, and environmental fate, with a particular emphasis on effects on humans as well as an analysis of the European Union’s efforts to regulate and remediate PFAS.
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.
Sulfonamide Functional Head on Short-Chain Perfluorinated Substance Drives Developmental Toxicity
25 Jan 2022 | iScience
FBSA exposure leads to changes in DNA that result in abnormal body structure and disrupted gene expression in human model species.
[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.
