the world of toxicology



us that chemicals are the building blocks of our bodies and our world



the potential health effects from exposures to chemicals



the public about toxicology in our daily lives


Our mission is to enhance public understanding of toxicology through access to objective, science-based information on the safety of chemicals and other agents encountered in daily life.

What is Toxicology?

The Science

Toxicology is the study of the adverse effects of chemical, physical or biological agents on living organisms and the ecosystem, including the prevention and amelioration of such adverse effects. We are made up of chemicals and they are a part of everything we do. Whether naturally occurring or man-made, our bodies are constantly interacting with chemicals in our food, products, and environment.

TEF’s Goal

TEF provides the public with access to reliable scientific information in order to make informed decisions about chemical exposures. Everyone is exposed to chemicals. Whereas some types of exposure are beyond our control, we as a society have the power to accept or reject certain exposures. Individuals also often have choices in the type and amount of certain chemicals to which each of us may be exposed. No chemical, biological or physical agent in our environment is completely without risk, but risk is sometimes worth taking if the benefits outweigh the risk.
