Where adequate information is not available, ATSDR, in conjunction with the NTP, is required to assure the initiation of a program of research designed to determine the health effects of such substances. Under the Substance Specific Applied Research Program, ATSDR has identified priority data needs for 60 hazardous substances and transmitted a subset of these to the NTP for consideration in its toxicology testing program.
