The National Toxicology Program is an interagency program established in 1978 to coordinate toxicology research and testing across the Department of Health and Human Services. The program was also created to strengthen the science base in toxicology, develop and validate improved testing methods, and provide information about potentially toxic chemicals to health regulatory and research agencies, scientific and medical communities, and the public.
NTP is headquartered at the National Institute of Environmental Health Sciences (NIEHS). NIEHS is one of three core agencies that provide support for NTP activities. The other two agencies are:
- The U.S. Food and Drug Administration, primarily through its National Center for Toxicological Research (NCTR/FDA); and
- National Institute for Occupational Safety and Health of the Centers for Disease Control and Prevention (NIOSH/CDC)
The Director of the NIEHS/NIH, Dr. Linda S. Birnbaum, serves as the NTP Director. Dr. John Bucher, Associate Director of NTP, assists the Director in the daily management of NTP. The NTP Division within the NIEHS provides operational support.
