In the sixteenth century, Paracelsus observed that every substance is poisonous. Toxicologists strive to determine the toxicity of substances using methodologies such as computer modeling, cellular and genetic toxicology, and animal studies. Toxicity evaluations, toxicity clearances, wildlife toxicity assessments, and environmental health assessments are some of the products used to evaluate risks to Soldiers, civilians and the environment posed by military-unique and military-relevant substances.


All Substances Are Poisons: Toxicology Overview

The US Army Public Health Command provides data about the toxicity of military-unique and military-relevant compounds and the risks they pose to Soldiers, civilians and the environment.

Animal Models

This page discusses using animal models for toxicology experiments.

Genetic and Cellular Toxicology

This page discusses assays used by the USAPCH for genetic and cellular toxicology.

Toxicological Computer Modeling

The computer modeling page describes the benefits of "in silico" experiments and the types of modeling used by the USAPHC.

Toxicology Partner Organizations

The Collaboration page lists some of the entities with which the USAPHC joins forces.


Exposure Modeling

Army Risk Assessment Modeling System (ARAMS)

Toxicity Clearances

A toxicity clearance is a toxicological evaluation of materials prior to their introduction into the Army supply system.

Wildlife Toxicity Assessments

a standard method for developing toxicological profiles and toxicity reference values for military-related substances that may pose risks to wildlife
