National Toxicology Program

The NTP announced the nominations proposed for review for the 12^th RoC in the Federal Register and invited public input. The NTP selected the candidate substances for the 12^th RoC from these nominations and is proceeding with their review following the review process for the 12^th RoC. Two important elements in this process are (1) the public peer review of draft background documents by ad hoc scientific expert panels and (2) the public peer review of draft substance profiles for candidate substances by the NTP Board of Scientific Counselors. In addition, the NTP will, on a trial basis, prepare a response to public comments for the 12^th RoC. Select "other nominations" for information on nominations not selected as candidate substances.
