1. Sources for this Digest

The material content of most of the texts on Level 3 (Questions 2 to 6) is directly sourced from the  Executive Summary of the Assessment of the health risk of dioxins  : re-evaluation of the Tolerable Daily Intake (TDI), a leading scientific report produced in 1998 by a large international panel of scientists of the IPCS (International Programme on Chemical Safety) and WHO (World Health Organization).

Note from the editor: In 2008, this source is still considered a valid reference. Since 1998, there have been no big changes in our scientific understanding of dioxins - other than to strengthen the conclusions that dioxins are bad actors. General dioxin levels have since continued to drop both in the environment and in people.

The Level 3 texts of the introduction "1. What are dioxins" come from a different source:

The Levels 1 & 2 have been written by Dr. Ludo Holsbeek in collaboration with the GreenFacts team.
