NTP Publishes Revised Technical Reports on the Toxicity Studies of Perfluoroalkyl Sulfonates and Perfluoroalkyl Carboxylates
On July 28, 2022, the National Toxicology Program (NTP) announced that the following revised Technical Reports on the Toxicity Studies are available on the NTP website:
- Perfluoroalkyl Sulfonates (Perfluorobutane Sulfonic Acid, Perfluorohexane Sulfonate Potassium Salt, and Perfluorooctane Sulfonic Acid) Administered by Gavage to Sprague Dawley (Hsd:Sprague Dawley SD) Rats (Revised TOX-96); and
- Perfluoroalkyl Carboxylates (Perfluorohexanoic Acid, Perfluorooctanoic Acid, Perfluorononanoic Acid, and Perfluorodecanoic Acid) Administered by Gavage to Sprague Dawley (Hsd:Sprague Dawley SD) Rats (Revised TOX-97).
According to NTP, transcription errors were identified in these reports, and an audit was conducted. NTP revised and republished the reports with an appendix that identifies the corrections. NTP notes that the final tables are available in the Chemical Effects in Biological Systems (CEBS) database.
