The FDA joins the EPA, the National Institute of Environmental Health Sciences' National Toxicology Program (NTP), and the National Institutes of Health's Chemical Genomics Center (NCGC) in the Tox21 collaboration, which uses federal agencies' combined resources to develop methods to more effectively predict how chemicals will impact human health and the environment. According to the NTP, "The addition of the FDA...allows biomedical researchers and regulatory scientists...to more rapidly screen chemicals and find more effective ways to protect the health of the public."
