Throughout their lives, people are exposed to thousands of chemicals in food, household cleaning products, medicines and the environment. However, scientists know little about the potential for most of these substances to be hazardous to human health (i.e., their toxicity).

Toxicology in the 21st Century (Tox21)
Tox21 Enables Researchers to Rapidly Conduct Toxicity Testing
Traditional toxicity testing can be costly and time-consuming. To streamline the process, NCATS scientists and collaborators started the Tox21 project and created an extensive chemical library of more than 10,000 compounds.
