• Bioaccumulation of PFOS Isomers in Transporter Proteins

  Published on January 8, 2026
  In this study, the bioaccumulation potential of linear PFOS and five different branched isomers in the long-chain fatty acid (LCFA) transport protein from Escherichia coli (E. coli) is investigated using molecular dynamics simulations.

• Source Fingerprinting of PFOA via Full- and Intramolecular Stable Isotope Ratios of Carbon Using Orbitrap-IRMS

  Published on December 13, 2025
  Scientists developed an electrospray ionization Orbitrap-IRMS method that can be used as a forensic tool for the source attribution of PFAS contaminants.

• Interaction of ADONA with neutral and charged clay interfaces: molecular insights

  Published on October 21, 2025
  Interfacial adsorption structures and dynamic properties of ADONA vary substantially between different mineral surfaces, and the adsorption mechanism strongly depends on the surface charge of the minerals examined.

• Gas Phase Thermochemistry for Perfluoroalkyl Carboxylic Acids

  Published on September 16, 2025
  Thermodynamic energies of perfluoroalkanoic acids have been predicted.

• Per- and polyfluoroalkyl substances in agricultural systems: Human dietary exposure via beef raised on corn stover from a field with contaminated biosolids

  Published on September 9, 2025
  Corn kernels accumulate little to no PFAS even when soil concentrations are elevated, direct measurement of PFAS in crops can reduce uncertainty in exposure and risk assessment, and PFOS can biomagnify via the soil-stover-cattle-human pathway.

• Per- and polyfluoroalkyl substances in agriculture: environmental fate, bioaccumulation and management

  Published on September 5, 2025
  This paper further briefs toxicological implications of PFAS to human and ecosystem health, highlights current remediation and mitigation strategies, and assesses regulatory frameworks governing PFAS in the agricultural environment.

• Adsorption and Dynamic Characteristics of PFAS Mixtures with Kaolinite: Molecular Insights into the Impact of Chain Length and Functional Group

  Published on July 10, 2025
  This study evaluates the impact of PFAS chain length and functionalities in a binary mixture on the interactions with soil minerals.

• Per- and polyfluoroalkyl substances in untreated and treated sludge/biosolids from 27 water resource recovery facilities across the United States and Canada

  Published on February 23, 2025
  This surveillance of 27 WRRFs throughout the United States and Canada provides information on the range of PFAS concentrations in pre-stabilized sludge and post-stabilized product.

• PFAS in agroecosystems: Sources, impacts, and opportunities for mitigating risks to human and ecosystem health

  Published on December 24, 2024
  The work contained in this special section can be used to help guide future decisions related to PFAS guidelines, policies, and regulations in agroecosystems intended to protect human and ecological health.

• Interfacial adsorption and dynamics of fluorotelomers with soil minerals – mechanistic insights

  Published on November 8, 2024
  This study provides cluster size dependent diffusion behavior of surface adsorbed fluorotelomer molecules in each clay mineral. These mechanistic insights are necessary to understand the environmental footprint of fluorotelomers around contaminated sites.
