• Are resource recovery insects safe for feed and food? A screening approach for bioaccumulative trace organic contaminants

  Science

  1 Jun 2022 | Sci. Total Environ.

  Four PFAS (PFBA, PFOA, PFBS, and PFOS) did not bioaccumulate in larvae, and non-target analysis revealed emerging PFAS present in larvae and almond hulls.

• Assessment of Bioactive Surfactant Levels in Selected Cereal Products

  Science

  30 May 2022 | Applied Sciences

  The most frequently detected compound was PFOA, which was quantified in 65.2% of samples, while PFBA was present in the majority of cereal based products.

• Absorption and elimination of per and poly-fluoroalkyl substances substitutes in salmonid species after pre-fertilization exposure

  Science

  4 Jan 2022 | Sci Total Environ

  PFBA, PFBS, and GenX were eliminated faster than PFOS or PFOA in fish.

• [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.

• Poly- and Perfluorinated Alkyl Substances in Air and Water from Dhaka, Bangladesh.

  Science

  30 Nov 2021 | Environ Toxicol Chem

  The prevalence of 6:2 FTOH and PFBA across sites likely reflects their usage in textile manufacturing and could indicate the industry's switch to shorter chain PFAS.

• 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

  News

• EPA proposal could put PFAS on contaminant list, UW experts support decision

  Policy

  12 Oct 2021

  Wisconsin Attorney General Josh Kaul supported the U.S. Environmental Protection Agency’s proposal to include per- and polyfluoroalkyl substances in the Contaminant Candidate List 5.

• Perfluoroalkyl substances are linked to incident chronic spontaneous urticaria: A nested case-control study

  Science

  5 Oct 2021 | Chemosphere

  Serum PFASs are associated with an increased risk of incident chronic hives, and PFBA and PFHpA might be the effective compounds.

• Assessment of per- and polyfluoroalkyl substances in Biscayne Bay surface waters and tap waters from South Florida

  Science

  17 Sep 2021 | Sci Total Environ

  The average total PFAS was higher in tap water than in surface waters, whereas the most predominant and frequently detected PFAS were PFBA, PFBS, PFPeA, PFHxA, PFHxS, PFOA, and PFOS.

• [Blog] Guidance on New PFAS Reporting Rule for Manufacturers

  Science

  30 Aug 2021 | Int J Hyg Environ Health

  Contrary to previous findings, analysis of short-chain PFAS in human lungs and kidney indicates PFBA is not likely to accumulate in these tissues.

• Ineffectiveness of ultrasound at low frequency for treating per- and polyfluoroalkyl substances in sewage sludge

  Science

  4 Aug 2021 | Chemosphere
