OVERVIEW OF THE CONFERENCE PROGRAM
John G. Keller, Ph.D.

The Conference on EPA’s Characterization of Dioxin Risks: Do Background Dioxin Exposures Pose a Human Health Threat? was held in Arlington, Virginia on October 6, 2000. This one-day conference was organized by the International Society of Regulatory Toxicology and Pharmacology, the American Bar Association Special Committee on Pesticides, Chemical Regulation and Right to Know, and the Chlorine Chemistry Council. This conference addressed a number of scientific, human risk, and health policy issues related to EPA’s recent draft dioxin risk reassessment and characterization, such as:

  • Does EPA accurately describe the science concerning dioxin’s potential cancer and non-cancer risks?
  • Is the human population at risk?
  • Is the U.S. food supply safe?
  • What are the public health consequences of EPA’s draft risk characterization?

For additional background information, the reader is referred to the Focus exposé which is the next section of the Proceedings.

This conference permitted a broad and candid discussion of all the relevant scientific, regulatory and public policy issues by recognized experts and also included input from conference attendees. Terry Quill and Michael Gough provided informed perspectives on historical and current dioxin issues. This was followed by three panel discussions which addressed the major issues in detail.

  • PANEL 1 - Chaired by Terry F. Quill, discussed the potential human cancer and non-cancer risks posed by dioxin exposures.
  • PANEL 2 - Chaired by Herbert Estreicher, discussed food as a major route of dioxin exposures
  • PANEL 3 - Chaired by C.T. "Kip" Howlett, discussed public policy issues.

Complete copies of the presentations for each panel member are included in these Proceedings. In order to evaluate how well the conference accomplished its objectives, an insightful Synopsis, prepared by Michael Gough, is presented as the final section of these Proceedings.
