• [Webinar] Eliminating Unnecessary PFAS in Building Materials

  Events

  13 May 2021

  This one-hour presentation will introduce the Green Science Policy Institute's new report, "Building a Better World: Eliminating Unnecessary Uses of PFAS in Building Materials." Space is limited.

• US chemical industry spent $61M to fend off PFAS regulations

  Policy

  4 May 2021

  Campaign finance records reveal that seven of largest PFAS producers and their industry trade groups spent at least $61 million during 2019 and 2020, the majority of which did not comprise campaign donations but instead funded lobbying efforts aimed at members of Congress and Donald Trump’s administration.

• Serum concentrations of per−/polyfluoroalkyl substances and risk of type 2 diabetes: A case-control study

  Science

  4 May 2021 | Sci. Tot. Env.

  PFHxS and PFHpA exposure were associated with an increased risk of developing type 2 diabetes.

• Diffusion of perfluoroalkyl acids through clay-rich soil

  Science

  4 May 2021 | J Contam Hydrol

  Surface diffusion serves a potentially important role for strongly sorbing PFAAs in clay-rich soils.

• The Case for Direct Measures of Soil-to-Groundwater Contaminant Mass Discharge at AFFF-Impacted Sites

  Science

  4 May 2021 | Environ Sci Technol

  This perspective provides a rationale for why alternative approaches are critically necessary and proposes a practical solution to accurately assess PFAS transport within unsaturated vadose zone soils.

• Microwave regeneration of granular activated carbon saturated with PFAS

  Science

  4 May 2021 | Water Res

  Multiple cycles of microwave treatments were found to successfully regenerate activated carbon saturated with PFOA and PFOS.

• Interference of C6O4 on platelet aggregation pathways: Cues on the new-generation of perfluoro-alkyl substance

  Science

  4 May 2021 | Environ Int

  A PFAS alternative, C6O4, was associated with an increased risk of cardiovascular events.

• Occurrence of per- and polyfluoroalkyl substances (PFASs) in wastewater of major cities across China in 2014 and 2016

  Science

  4 May 2021 | Chemosphere

  Population density and per capita gross domestic product have positive correlations with the concentration of PFBA, PFOA, PFHxA, and total-PFAS in wastewater.

• Immunotoxicity of Per-and Polyfluoroalkyl Substances: Insights into Short-Chain PFAS Exposure

  Science

  3 May 2021 | Toxics

  Understudied PFAS have toxicological potential but require additional investigation across endpoints and species, including humans, to understand health effects via drinking water exposure.

• Towards a Long-Chain Perfluoroalkyl Replacement: Water and Oil Repellent Perfluoropolyether-Based Polyurethane Oligomers

  Science

  3 May 2021 | Polymers (Basel)

  A short-chain PFAS was developed to replace legacy chemicals without losing functionality.

• PFAS Paper Mill Settlement Reflects Growing Trend

  News

  28 Apr 2021 | National Law Review

  Just a few days ago, an $11.9 million settlement was announced in a Michigan lawsuit in which a class of approximately 3,000 plaintiffs alleged that a PFAS manufacturer and a PFAS-using paper mill contaminated drinking water supplies, thereby polluting the environment and placing nearby citizens at increased risk of adverse health effects.

• Bioactivity Profiling of Per- and Polyfluoroalkyl Substances (PFAS) Identifies Potential Toxicity Pathways Related to Molecular Structure

  Science

  28 Apr 2021 | Toxicology

  Using 142 PFAS, key structural features were associated with receptor activity which can inform the design of new structures devoid of biological activity.
