• ‘Forever chemicals’: What are PFAS and can we solve this persistent pollution problem?

  News

  19 Aug 2022 | Euronews

  We need to turn off the tap on PFAS pollution, and to do that we need to stop all unnecessary use of PFAS as soon as possible.

• The PFAS-Tox Database: A systematic evidence map of health studies on 29 per- and polyfluoroalkyl substances

  Science

  1 Aug 2022 | Environ. Int.

  In this summary of the PFAS-Tox Database we provide examples of data gaps and clusters revealed by the database, with the goal of helping direct future research efforts, facilitate systematic reviews (e.g. on immune effects, mixtures of PFAS, or effects of short chain PFAS), inform regulatory risk assessments, and improve opportunities for cross-disciplinary coordination.

• Per- and polyfluoroalkyl substances (PFASs) in consumable species and food products

  Science

  28 Jul 2022 | J Food Sci Technol

  This review found that legacy PFAS remain in high abundance and that proximity to factories and fluorochemical industries results in potentially hazardous levels of PFAS contamination in all types of food products.

• Common questions about PFAS, answered

  News

  20 Jul 2022 | The Hill

  Here, we lay out common questions related to PFAS, and their answers, and explain the next steps needed to address this potential pollutant, according to experts.

• Next Generation Per-and Poly-Fluoroalkyl Substances: Status and Trends, Aquatic Toxicity, and Risk Assessment

  Science

  19 Jul 2022 | EEH

  Future uses of PFAS remain uncertain in the face of governmental regulations and production bans, but replacement PFAS will continue to emerge on the world market and in the environment, raising concerns about their general lack of information on mechanisms and toxic potencies.

• [Opinion] Speaking the Same Language: The Need for Accurate and Consistent Reporting of Novel Per-and Polyfluoroalkyl Substances

  Science

  18 Jul 2022 | ES&T

  Recommendations presented in this viewpoint are encouraged for all PFAS researchers performing non-targeted analysis to prevent miscommunication and misidentification of PFAS compounds.

• Characterization of Per- and Polyfluorinated Alkyl Substances Present in Commercial Anti-fog Products and Their Adipogenic Activity

  Science

  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.

• Combined Use of Total Fluorine and Oxidative Fingerprinting for Quantitative Determination of Side-Chain Fluorinated Polymers in Textiles

  Science

  3 Jan 2022 | ES&T

  A method was developed to determine the side-chain fluorinated polymer concentrations in terms of the side chain mass, as opposed to fluorine equivalents, facilitating the estimation of the structure and quantity of PFAA degradation products in medical textiles.

• Insufficient evidence for the existence of natural trifluoroacetic acid

  Science

  3 Jan 2022 | Environ. Sci.: Processes Impacts

  The authors argue that there is not sufficient evidence that TFA occurs naturally, contrary to previous claims.

• New Additions to the Proposition 65 List

  Policy

  20 Dec 2021

  Over the past week, several new PFAS have been added to California’s Proposition 65 list.

• Development and validation of an LC-MS/MS method for the quantitation of 30 legacy and emerging per- and polyfluoroalkyl substances (PFASs) in human plasma, including HFPO-DA, DONA, and cC6O4

  Science

  20 Dec 2021 | Anal Bioanal Chem

  An assay was developed suitable for large-scale analyses of a wide range of legacy and emerging PFAS in human plasma.

• [Press Release] Rep. Sherrill Holds Science, Space, and Technology Committee Hearing on PFAS Research and Development

  Policy

  13 Dec 2021

  Representative Mikie Sherrill (NJ-11) held a hearing on PFAS to discuss the role of federal research and development to better understand and address the growing problem and expand public understanding about PFAS in NJ-11 and across the country.

• Distribution, source identification and health risk assessment of PFASs in groundwater from Jiangxi Province, China

  Science

  30 Nov 2021 | Chemosphere

  Monitoring in China suggests that PFBA, PFPeA, 6:2 FTS and F–53B are broadly used replacements of PFOA and PFOS with estimated daily intakes of short-chain PFCAs higher than that of PFOA.

• A New OECD Definition for Per- and Polyfluoroalkyl Substances

  Science

  16 Nov 2021 | Environ Sci Technol

  The Organisation for Economic Co-operation and Development and the United Nations Environment Programme expanded on their definition of PFAS to include fluorinated substances that contain at least one fully fluorinated methyl or methylene carbon atom.

• [Blog] The Big Reveal: Hundreds of Health Studies on Next Gen PFAS
