PFAS in vitro data set
Results of single concentration and concentration response testing of 165 PFAS samples from the USEPA ToxCast chemical library in nine (9) thyroid relevant assays. Chemicals were first screened in single concentration ('Single Concentration' tab) and then those chemicals with 50% or greater activity were further tested in concentration-response mode ('Concentration Response' tab). This dataset is associated with the following publication: Degitz, S., J. Olker, J. Denny, P. Degoey, P. Hartig, M. Cardon, S. Eytcheson, J. Haselman, S. Mayasich, and M. Hornung. In vitro screening of per- and polyfluorinated substances (PFAS) for interference with seven thyroid hormone system targets across nine assays. TOXICOLOGY IN VITRO.

Systematic Evidence Map for the Per- and Polyfluoroalkyl Substances (PFAS) Universe
공공데이터포털
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.

We used systematic evidence map methods to summarize the available epidemiological and animal bioassay evidence for an expanded set of ~345 PFAS that were prioritized in 2019 by the EPA’s Center for Computational Toxicology and Exposure (CCTE) for in vitro toxicity and toxicokinetic screening. This work builds upon our previously published evidence map for ~150 PFAS chemicals (Carlson et al. 2022, https://doi.org/10.1289/EHP10343).
