History

A concise historical narrative of NAICS Code 621511-25 covering global milestones and recent developments within the United States.

  • Toxicology has been a field of study for centuries, with early examples of toxicology dating back to ancient Greece and Rome. The first recorded use of poison as a weapon was in 331 BC, when Alexander the Great was allegedly poisoned. In the 16th century, Paracelsus, a Swiss physician, is credited with founding the field of toxicology. In the 19th century, the Industrial Revolution led to an increase in toxic exposure, which led to the development of modern toxicology. In the United States, the Toxic Substances Control Act was passed in 1976, which regulates the manufacture, import, and processing of chemicals. In recent years, the field of toxicology has expanded to include environmental toxicology, forensic toxicology, and clinical toxicology, among others.
