• Toxic ‘forever chemicals’ found in pesticide used on millions of Mass. acres when spraying for mosquitoes

  News

  1 Dec 2020 | Boston Globe

  Now, after years of criticism from environmental advocates who have long raised health concerns about the expensive treatment known as Anvil 10+10, the pesticide has been found to also contain an array of toxic compounds known as PFAS.

• The high persistence of PFAS is sufficient for their management as a chemical class

  Science

  1 Dec 2020 | Environ Sci Process Impacts

  We argue that this high persistence is sufficient concern for their management as a chemical class, and for all "non-essential" uses of PFAS to be phased out.

• Rapid Characterization of Emerging Per- and Polyfluoroalkyl Substances in Aqueous Film-Forming Foams Using Ion Mobility Spectrometry-Mass Spectrometry

  Science

  24 Nov 2020 | Environ Sci Technol

  Using analytical chemistry techniques PFAS in AFFF were rapidly characterized.

• [Informational Webinar] EPA's Innovative Ways to Destroy PFAS Challenge

  Events

  23 Nov 2020

  EPA is partnering with the other stakeholders, to co-sponsor a technical challenge regarding the destruction of PFAS. The challenge asks solvers to submit detailed plans for a non-thermal way of destroying PFAS in AFFF, while creating the least amount of potentially harmful byproducts with a $50,000 prize.  

• Suggestions for Improving the Characterisation of Risk from Exposures to Per and Polyfluorinated Alkyl Substances (PFAS)

  Science

  22 Nov 2020 | Environ Toxicol Chem

  Here we propose methods that consider maximizing the use of disparate data streams, seeking patterns, and proposing biological-based approaches to evidence integration towards informed criteria development.

• PFAS Exposure Pathways for Humans and Wildlife: A Synthesis of Current Knowledge and Key Gaps in Understanding

  Science

  16 Nov 2020 | Environ Toxicol Chem

  Here we synthesize current understanding of the magnitudes and methods for assessing human and wildlife exposures to PFAS.

• The Biden plan to secure environmental justice

  Policy

  10 Nov 2020

  Biden will tackle PFAS pollution by designating PFAS as a hazardous substance, setting enforceable limits for PFAS in the Safe Drinking Water Act, prioritizing substitutes through procurement, and accelerating toxicity studies and research on PFAS.

• Per- and Polyfluoroalkyl Substances in Dust Collected from Residential Homes and Fire Stations in North America

  Science

  10 Nov 2020 | Environ Sci Technol

  PFOS, PFOA, PFHxS, PFNA, and 6:2 diPAP were significantly higher in dust from fire stations than from homes, and 8:2 FTOH was significantly higher in homes than in fire stations.

• From Waste Collection Vehicles to Landfills: Indication of Per- and Polyfluoroalkyl Substance (PFAS) Transformation

  Science

  3 Nov 2020 | ES&T L

  Leachate from waste collection vehicles was tested and found to contain PFAS precursors suggesting precursor transformation to PFAAs during the course of landfill disposal.
