Directs the Secretary of Health, Education, and Welfare to provide for the design of a protocol for and the conduct of an epidemiological study to determine the long-term adverse health effects in persons of various populations (such as chemical, agricultural, and Forest Service workers) who were exposed to dioxins produced during the manufacture of phenoxy herbicides.
