The following excerpts are from slide transparencies prepared by the U.S. EPAs Office of Research & Development (ORD), titled A Status Briefing for the Deputy Administrator, dated 2-14-92.
*Dioxin does cause cancer in humans.
*Cancer may not be the most sensitive toxic response
resulting from dioxin exposure. Immunotoxicity
and reproductive effects appear to occur at body
burdens that are approximately 100 times lower than
those associated with cancer.
*Recent data indicate that there may not be a
threshold for certain responses to dioxin...
*Recent evidence has strengthened the conclusion
that the sensitivity of humans is similar to that
of experimental animals...
*Current exposure levels to dioxin and related
compounds appear to place people at or near a
body burden where sensitive responses may
occur, especially for subpopulations at
high-end of exposure, e.g., nursing infants,
recreational and subsistence anglers...
*ORD scientists have reached the tentative
conclusion that dioxin exposure may have been
responsible for the decline of Lake Trout in Lake
Ontario as a result of the reproductive toxicity of
The hearings are being held by the US EPAs Office of Research and Development (ORD) which is responsible for evaluating the evidence of dioxin on human and ecological health. The purpose of this meeting is [t]o give a status and progress report to the public on all elements of the scientific reassessment of dioxin; to answer relevant questions from the public; and to receive oral and written comment from the public. At this hearing the following people will help conduct the hearing: Dr. Peter Preuss, Director, Office of Technology Transfer & Regulatory Support, will give an overview and introduction; Dr. William Farland, Director, Office of Health & Environmental Assessment, will give an update of EPAs Scientific Reassessment of Dioxin; Dr. Linda Birnbaum, Director, Environmental Toxicology Division, Health Effects Research Laboratory, Research Triangle Park, will give update on health research in support of the dioxin reassessment; Dr. George Lucier, Chief of the Laboratory of Biochemical Risk Analyses, National Institute of Environmental Health Sciences, Research Triangle Park, will present the development of dose-response models for evaluating the human health risks from exposures to dioxin-like compounds; Mr. John Schaum, Exposure Assessment Group, Office of Health & Environmental Assessment, will present information on estimating exposures to dioxin-like compounds; Dr. Philip Cook, Environmental Research Laboratory, Duluth, MN, will present an ecological risk characterization.
EPA VIDEO AVAILABLE ON 1st DIOXIN REASSESSMENT HEARING. Instead of a written transcript, the EPA videoed the 1st Public Hearing on EPAs Reassessment of Dioxin held on 11-15-91 (see Waste Not #170) to help make the hearings more accessible to the public. This video is available to the public at each of the US EPAs regional offices. This video is 5 hours, 49 minutes. Copies of this video can be obtained from the following individuals who comprise the Regional Scientists Program of the EPAs Office of Research & Development. They were sent a copy of the video to share with the public. The name of the video is: EPAs Scientific Reassessment of Dioxin: 11-15-91 Public Hearing. The 2nd Dioxin Public Hearing will also be videod.
