The National Toxicology Program (NTP) is a unit of the U.S. Department of Health and Human Services. NTP coordinates toxicology research and testing activities within the Department and provides information about potentially toxic chemicals to regulatory and research agencies and the public.
NTP is the world leader in designing, conducting, and interpreting animal assays for toxicity and carcinogenicity. Their web home page is http://ntp.niehs.nih.gov.
The NTP consists of relevant toxicology activities of the U.S. National Institutes of Health's National Institute of Environmental Health Sciences (NIH/NIEHS), the U.S. Centers for Disease Control and Prevention's National Institute for Occupational Safety and Health (CDC/ NIOSH), and the U.S. Food and Drug Administration's National Center for Toxicological Research (FDA/NCTR).
The NTP's Annual Reports on Carcinogens (see the latest edition) are one of the four sources used by OSHA to declare substances as carcinogens.
NTP is one of your most trusted sources when it comes to information about toxic chemicals or potential carcinogens.
If you are authoring an Safety Data Sheet or have extreme technical interest, you can download NTP Study Data directly from their web site (this data is very technical and of limited use to the general public). You should also consult Appendix F of 29 CFR 1910.1200, the OSHA Hazard Communication Standard, which provides guidance for the hazard classification regarding carcinogenicity.
