Adolescents with a healthy dietary pattern had on average higher PFAA serum levels.
Per- and Polyfluoroalkyl Substances (PFAS) in Facemasks: Potential Source of Human Exposure to PFAS with Implications for Disposal to Landfills
6 Apr 2022 | ES&T
Preliminary findings indicate that wearing masks treated with high levels of PFAS for extended periods of time can be a notable source of PFAS exposure and have the potential to pose a health risk.
Perfluorooctanoate and perfluorooctane sulfonate in umbilical cord blood and child cognitive development: Hamamatsu Birth Cohort for Mothers and Children (HBC Study)
6 Apr 2022 | Environ Int
Measurements of PFOA and PFOS in the cord blood of nearly 600 mother-infant pairs found mixed associations between PFAS concentrations and cognitive development.
Assessment of the Emerging Threat Posed by Perfluoroalkyl and Polyfluoroalkyl Substances to Male Reproduction in Humans
6 Apr 2022 | Front Endocrinol (Lausanne)
This review describes the effects of PFAS on human health, especially relating to male reproduction, such as associations between PFAS exposure and the incidence of testicular cancer and the reduction in semen quality.
Determination of total reducible organofluorine in PFAS-impacted aqueous samples based on hydrated electron defluorination

[Report] Per- and Polyfluoroalkyl Substances and Alternatives in Coatings, Paints and Varnishes (CPVs)
31 Mar 2022 | OECD
This report examines the commercial availability and current uses of PFAS and non-PFAS alternatives in coatings, paints, and varnishes (CPVs) and was developed within the framework of the OECD/UNEP Global PFC Group.
Time to Break the “Lock-In” Impediments to Chemicals Management
31 Mar 2022 | ES&T
The authors suggest that to break “lock-in” (the interactions between economic, social, technological, and political dynamics that reinforce global reliance on chemicals) and address the global threat of chemical pollution, current approaches to hazardous chemical management should be broadened to consider all factors contributing to lock-in, including both supply and demand on national and international scales.
Extracting and Comparing PFAS from Literature and Patent Documents using Open Access Chemistry Toolkits
31 Mar 2022 | Comput. Theor. Chem.
Three open access chemical information toolkits were used to automatically search for PFAS based on structure, and all yielded different results. Overall, ~1.7 million PFAS were identified from patents and ~27 thousand from COnnecting REpositories (CORE).
Widening the Lens on PFASs: Direct Human Exposure to Perfluoroalkyl Acid Precursors (pre-PFAAs)
31 Mar 2022 | Environ Sci Technol
This article outlines recent progress and recommends expanding the discussion of human PFAS exposure to include the pre-PFAA subclass.
Temporal Trends of Organochlorine- and Perfluorinated Contaminants in a Terrestrial Raptor in Northern Europe over 34 Years (1986-2019)
31 Mar 2022 | Environ Toxicol Chem
Most legacy organochlorines and PFOS have not reached lower, stable background levels, and voluntary elimination of PFCAs still have not resulted in declining levels in tawny owls in central Norway.
Municipal solid waste incineration (MSWI) ash co-disposal: Influence on per- and polyfluoroalkyl substances (PFAS) concentration in landfill leachate
31 Mar 2022 | Waste Manag
PFAS concentrations in leachates are higher when PFAS-rich unburned wastes are disposed of alongside incineration ash, even if the unburned fraction is small.
Global Exposure to Per- and Polyfluoroalkyl Substances and Associated Burden of Low Birthweight
31 Mar 2022 | Environ Sci Technol
Human exposure to PFOA may have contributed to approximately 500,000 cases per year of low birth weight during the past two decades, predominantly from Asian regions.
Perfluoroalkyl acid and bisphenol-A exposure via food sources in four First Nation communities in Quebec, Canada
31 Mar 2022 | Public Health Nutr
PFNA and BPA concentrations were highest amongst First Nations people compared to other Canadian groups, with dairy products having the highest concentrations.
Per- and polyfluoroalkyl substances (PFASs) in the blood of police and Beagle dogs from Harbin, China: Concentrations and associations with hematological parameters
28 Mar 2022 | Chemosphere
Dominant PFAS in the blood of dogs were found to be PFOA, PFBA, and PFOS, and PFAS exposure was linked to many changes in biochemical blood parameters like cholesterol.
The relationship between multiple perfluoroalkyl substances and cardiorespiratory fitness in male adolescents
22 Mar 2022 | Environ. Sci. Pollut. Res.
Exposure to PFAS, mainly PFNA, is associated with a decrease in cardiorespiratory health in young men, possibly via alterations in white blood cell count.
