Throughout the ages, toxicological science has provided information that has shaped and guided society. Undertakings as diverse as the healing arts, war, agriculture, and regulation and policy making all have their groundings in toxicology.

Toxipedia's History of Toxicology section provides users with information on significant people and events that have shaped environmental and public health from antiquity to the postmodern era. As always, we encourage users to edit and add pages. With your help, Toxipedia will become the definitive resource on the history of public and environmental health. To explore an interactive poster on milestones of toxicology poster, see image below or see the Milestones of Toxicology page. To explore a few detailed issues and an active exhibit see the Toxicology History Room which contains posters and displays about toxicology. Lessons Learned provides a short introduction to a historic toxicological issue or event from which we learned better how to prevent hazards to protect human and environmental health. For books see the Toxicology History Library.

A daily calendar of events is also available at Toxicology On This Day.
