• Legacy and emerging airborne per- and polyfluoroalkyl substances (PFAS) collected on PM2.5 filters in close proximity to a fluoropolymer manufacturing facility

  Science

  9 Nov 2022 | Environ Sci Process Impacts

  Twelve emerging and ten legacy PFAS compounds were detected in aerosol samples around a fluoropolymer manufacturing facility at concentrations higher than at regional background sites, suggesting the manufacturing facility as the local source for these compounds.

• [Blog] Quibble with Kibbles: ‘Forever chemicals’ in pet food packaging add to perils at home

  News

  3 Nov 2022 | EWG

  The toxic “forever chemicals” known as PFAS create health hazards at home, since they’re used in everyday items like cookware and cosmetics – and new EWG research finds some popular pet food packaging can be yet another way we’re exposed to the perils of PFAS.

• Swimming with PFAS in public and private pools

  Science

  11 Oct 2022 | Chemosphere

  PFBA, PFHxA, PFHpA, PFOA, PFNA and PFBS were detected in every pool sample with most PFOA and PFOS levels above the new US EPA drinking water health advisory limits.

• Uptake of per-and polyfluoroalkyl substances (PFAS) by soybean across two generations

  Science

  3 Oct 2022 | J. Hazard. Mater. Adv.

  Considering widespread PFAS contamination and the ability of soybean plants to uptake PFAS, soybean seeds may need to be quantified for PFAS concentrations before their use in agricultural fields.

• Associations of prenatal exposure to perfluoroalkyl substances with preterm birth: A family-based birth cohort study

  Science

  7 Jul 2022 | Environ Res

  Higher family-level PFNA and PFDA exposure were associated with greater preterm birth risk, but the results on an individual level were contradictory.

• Occurrence, distribution, and input pathways of per-and polyfluoroalkyl substances in soils near different sources in Shanghai

  Science

  13 Jun 2022 | Environ. Pollut.

  Many PFAS were detected throughout soils, with highest concentrations near fire stations and industrial areas.

• Sorption of Per-and Polyfluoroalkyl Substances (PFAS) using Polyethylene (PE) microplastics as adsorbent: Grand Canonical Monte Carlo and Molecular Dynamics (GCMC-MD) studies

  Science

  17 May 2022 | Int. J. Environ. Anal. Chem.

  Several PFAS were found to easily sorb on to polyethylene microplastics, especially as pollutant concentration increased.

• Background release and potential point sources of per-and polyfluoroalkyl substances to municipal wastewater treatment plants across Australia

  Science

  24 Jan 2022 | Chemosphere

  About 60% of PFAS in Australian wastewater treatment plant influent was due to background release (at a rate of 8.1-24 μg/day/person) with the remaining ~40% due to point sources including industrial activities.

• Per-and Polyfluorinated Alkyl Substances (PFAS) Cycling within Michigan: Contaminated Sites, Landfills and Wastewater Treatment Plants

  Science

  4 Jan 2022 | Water Research

  Analysis of PFAS in Michigan waste found that landfill leachate is a primary source of PFAS to WWTPs, and treatment can increase PFAS concentrations up to 19x, yet long-chain PFAS like PFOA concentrate in biosolids.

• Minnesota Department of Health PFHxA health-based guidance for water

  Policy

  4 Jan 2022

  Minnesota's Department of Health updated its toxicological profile for PFHxA.

• Association between maternal serum concentration of perfluoroalkyl substances (PFASs) at delivery and acute infectious diseases in infancy

  Science

  20 Dec 2021 | Chemosphere

  Prenatal exposure to PFAS was associated with increased risks of diarrhea during the first year of life, and these effects were stronger among breastfed infants.

• [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.

• Tumorigenic activity of alternative per- and polyfluoroalkyl substances (PFAS): Mechanistic in vitro studies

  Science

  6 Dec 2021 | Sci Total Environ

  PFHxS has been associated with breast cancer in epidemiological studies, and this study demonstrated how this shorter-chain PFAS can affect cell proteins and cell proliferation.

• Species- and Tissue-Specific Chronic Toxicity Values for Northern Bobwhite Quail (Colinus virginianus) Exposed to PFHxA and a Binary Mixture of PFOS and PFHxA

  Science

  30 Nov 2021 | Environ Toxicol Chem

  PFHxA was more toxic to reproducing birds than either PFOS or a PFOS:PFHxS mixture, suggesting that avian PFAS toxicity is not necessarily additive.

• 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.
