Alcohol and Alcoholism

Although, chemically, there are many types of alcohol, drinks known as alcoholic beverages contain some percentage of ethyl alcohol, or ethanol, which is produced by the fermentation of yeast, sugars, and starches.  Common alcoholic beverages include wine, beer, and distilled spirits (e.g. whiskey, brandy, rum, vodka).  For this Tox Topic, we will adopt the generally used though imprecise term, alcohol, to refer to alcoholic beverages.  Despite overwhelming scientific evidence attesting to the deleterious and potentially devastating effects of alcohol, the bottom line ...

Hazard vs Risk

The words ‘hazard’ and ‘risk’ are often confused.  Understanding the difference between ‘a hazard’ and ‘a risk’ is important for understanding the role of toxicology in assessing risks.  A hazard is anything that can cause harm, whereas risk is the potential for a hazard to cause harm.   You can also think of it this way:  A hazard will not pose any risk to you unless you are exposed to enough of that hazard to cause harm.  Risks associated with hazards can be eliminated, or at least greatly reduced, by reducing exposure. The relationship between ...

Human Health Risk Assessment

The woman in this photo may not know she risks harming her unborn baby's health by smoking while pregnant.

Evaluating Chemical Risk” ...

What is Thirdhand Smoke?

Chemicals released in cigarette smoke that can stick to clothing walls and ceilings, carpets, draperies and furniture upholstery are referred to as thirdhand smoke.  Thirdhand smoke also includes new chemical products, some yet-to-be identified.   These are formed when components of cigarette smoke react with other constituents in the air and in surfaces on which they are deposited.  Identifying and measuring the various components of this newly-formed “chemical soup” pose a big challenge in addition to understanding their undesirable health effects. Thirdhand ...

Toxicology in the Classroom

This program has evolved with the changing times.   Currently TEF identifies our own Tox Topics aimed primarily at a general public audience that teachers may also find useful (see the Suitable for Classroom tab within Educational Resources).   Initially this program was able to provide professional development opportunities and disseminate quality curricula developed by others to teachers throughout the United States to support science education reform and increase toxicology literacy.    TEF is pleased to have contributed in the past to the following organizations ...
