Headquartered at the National Institute of Environmental Health Sciences (NIEHS), the National Toxicology Program (NTP) was established to meet the need for a program to address scientific, regulatory and Congressional concerns about the human health effects of chemical agents in our environment. The NTP coordinates toxicology testing programs; strengthens the toxicology science base; develops and validates testing methods; and provides information on potentially toxic chemicals and their harms.
