What is Toxicology?
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 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 a risk is sometimes worth taking if the benefits outweigh the risk.

The President has signed the Frank R. Lautenberg Chemical Safety for the 21st Century Act into law with strong support but some concerns from the toxicology community.
The President signed the bill to reform the Toxic Substances Control Act (TSCA) after 40 years. The compromise bill was the subject of much debate over the last five years and was the subject of a Task Force of the Society of Toxicology who worked to assure that strong scientific principles were embodied in the final language. While widely praised as a significant improvement over the current law, issues remained for some constituencies. See the link below for further information.
Graphic Cigarette Warnings Deter Smokers
A study described in The Science Times on June 14, 2016 provides the first hard evidence that graphic warnings aid in smoking control. Despite arguments to the contrary by the tobacco industry, a randomized controlled trial, published in the Journal of the American Medical Association, Internal Medicine, has provided evidence that pictorial warnings were more effective for both sexes and across races, ethnicities and socioeconomic levels. See the linked Science Times article for more information.
Questions and answers on the new study linking cell phones and cancer in rats
A preliminary study from the National Institute’s of Health (NIH) National Toxicology Program (NTP), released on May 27, 2016
, found that radiation from cellphones appears to have increased the risks that male rats developed tumors in their brains and hearts. But there are many caveats and some experts are debunking the study. See the linked New York Times article and video for further information.
We are very pleased by the positive response to our newest video Toxicity Today offering a comic taste of the “sometimes not poisonous and sometimes very poisonous” Botox® and the not-always-as-safe-as-you-think overconsumption of water!
TEF will continue to add website content that explains fundamental toxicology principles and concepts and addresses current toxicology-related topics to keep our viewers informed about the state-of-the-art of toxicology.
