NTP is a federal interagency program headquartered at NIEHS, whose goal is to develop and apply tools of modern toxicology and molecular biology to identify substances in the environment that may affect human health.
Assesses the evidence that environmental substances may cause health effects and provides opinions on whether they may be of concern given human exposure levels.
The Tox21 Program is an ongoing collaboration among federal agencies to characterize the potential toxicity of chemicals using cells and isolated molecular targets instead of laboratory animals.
