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.
Perfluoroalkyl Substances and Incident Natural Menopause in Midlife Women: The Mediating Role of Sex Hormones
22 Mar 2022 | Am. J. Epidemiol.
Participants with higher PFAS concentrations had a shorter time to natural menopause, and the effect of PFAS may be partially explained by variations in hormone concentrations.
Per-and Polyfluoroalkyl Substances and Risk of Myocardial Infarction and Stroke: A Nested Case–Control Study in Sweden
22 Mar 2022 | EHP
Exposure to PFAS was associated with increased cholesterol levels but not an increased risk of myocardial infarction or stroke.
Prenatal Exposure to Per- and Polyfluoroalkyl Substances and Child Growth Trajectories in the First Two Years
22 Mar 2022 | EHP
Associations of PFAS with child growth trajectory differed by sex as well as by when and at what concentration exposure occurred.
Understanding Public Perceptions of Per- and Polyfluoroalkyl Substances: Infodemiology Study of Social Media
21 Mar 2022 | J Med Internet Res
Government agencies can use social media research to understand the community sentiment on PFAS and then use social media to dispel misinformation, communicate scientific findings, and provide resources for relevant public health services.
