Thermal processing reduces PFAS concentrations in blue food - A systematic review and meta-analysis
12 Apr 2022 | Environ Pollut
An increase in cooking time and liquid/animal tissue ratio and a shorter PFAS chain length was associated with significant reductions in PFAS concentrations in seafood.
Perfluorinated alkyl substances in Canadian human milk as part of the Maternal-Infant Research on Environmental Chemicals (MIREC) study
12 Apr 2022 | Sci Total Environ
Primiparous women had elevated PFAS concentrations in milk relative to women who had children previously, and the region of material birth did not influence PFAS concentrations.
Effect of Plasma and Blood Donations on Levels of Perfluoroalkyl and Polyfluoroalkyl Substances in Firefighters in Australia: A Randomized Clinical Trial
12 Apr 2022 | JAMA Netw Open
Regular blood or plasma donations result in a significant reduction in serum PFAS levels for participant firefighters with a baseline PFOS level of 5 ng/mL or more; plasma donations reduced levels more quickly than blood donations.
Exploring the origin of efficient adsorption of poly- and perfluoroalkyl substances in household point-of-use water purifiers: Deep insights from a joint experimental and computational study
11 Apr 2022 | Sci Total Environ
Household point-of-use water purifiers using activated carbon can achieve up to 99% removal of 14 legacy and emerging PFAS in tap water.
Getting in control of persistent, mobile and toxic (PMT) and very persistent and very mobile (vPvM) substances to protect water resources: strategies from diverse perspectives
6 Apr 2022 | Environ. Sci. Eur.
The two most effective ways to get in control were identified to be source control through risk governance efforts, and enhancing market incentives for alternatives to PMT/vPvM substances by using safe and sustainable by design strategies
Healthy eating index and diet diversity score as determinants of serum perfluoroalkyl acid (PFAA) concentrations in a national survey of Swedish adolescents
6 Apr 2022 | Environ. Res.
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
5 Apr 2022 | Sci. Total Environ.
TROF provides a new indicator for PFASs contamination.
[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.
