Per- and polyfluoroalkyl substances (PFAS) are environmental contaminants of emerging concern. The temperature dependent gas-solid reaction of four gas-phase PFAS compounds (fluorotelomer alcohols or FTOHS) with calcium oxide is examined. This reaction shows potential as a PFAS disposal method that forms a stable and environmentally friendly end product, calcium fluoride. In addition to monitoring the destruction of the primary PFAS compound, byproducts of the thermal treatment reaction are identified and monitored to determine whether such products of incomplete destruction, which could also be a source of PFAS in the environment, are removed during the treatment process. This dataset is associated with the following publication: Riedel, T., A. Wallace, E. Shields, J. Ryan, C. Lee, and B. Linak. Low Temperature Thermal Treatment of Gas-Phase Fluorotelomer Alcohols by Calcium Oxide. CHEMOSPHERE. Elsevier Science Ltd, New York, NY, USA, 272: 0, (2021).

A list of structures (and other identifiers) of possible per- and polyfluoroalkyl substances (PFAS). The data provided in the PFAS Suspect List has been aggregated from public sources and users, including peer-reviewed literature, patent literature, and public websites. Therefore, the quality and accuracy of the compound names, structures, and other properties have not been validated. The National Institute of Standards & Technology does not endorse or provide any assessment of confidence with the information provided.

Samples were collected for a comparison method development study with the University of Minnesota and the U.S. Geological Survey (USGS) National Water Quality Laboratory (NWQL) in Lakewood, Colorado. Widely used liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods fail to capture large fractions of total organofluorine in environmental samples confounding the assessment and remediation of fluorinated pollution. Fluorine nuclear magnetic resonance (19F-NMR) is an inclusive method for organofluorine analysis that preserves chemical information about chemical compound classes of organofluorine.

This file contains data from accumulation of chloro perfluoro polyether carboxylate (Cl-PFPECA) and legacy perfluorocarboxylate PFAS in native vegetation and subsoil samples collected in New Jersey by New Jersey state government personnel. Samples were originally processed and extracted in Athens, GA EPA/ORD/NERL/EMMD laboratory by Tom Jenkins and John Washington. Samples were analyzed for PFAS on the Waters LC-MS/MS instruments in Athens, GA EPA/ORD/CEMM/EPD laboratory by Mary Davis, Marina Evich, and John Washington. Instrument output was reviewed and optimized by Mary Davis, Marina Evich, and John Washington. This dataset is associated with the following publication: Davis, M., M. Evich, S. Goodrow, and J. Washington. Environmental Fate of Cl-PFPECAs: Accumulation of Novel and Legacy Perfluoroalkyl Compounds in Real-World Vegetation and Subsoils. ENVIRONMENTAL SCIENCE & TECHNOLOGY.

We used systematic evidence map methods to summarize the available epidemiological and animal bioassay evidence for an expanded set of ~15,000 PFAS that were identified as PFAS by EPA's Center for Computational Toxicology and Exposure (CCTE). This work is a continuation of our previous 2022 and 2024 SEMs that inventoried evidence on a separate set of ~500 PFAS (Carlson et al, 2022, https://doi.org/10.1289/EHP10343; Radke et al, 2022, https://doi.org/10.1289/EHP11185; Carlson et al., 2024; https://doi.org/10.1289/EHP14191) and a 2023 evidence map on an additional 345 PFAS (Shirke et al. 2024, https://doi.org/10.1289/EHP13423 ). The comprehensive PFAS dashboard includes evidence identified from our past SEMs and completed US EPA assessments. This dataset is associated with the following publication: Shirke, A., E. Radke, R.
