What epidemiology is, and why it's important? Risk Bites provides a simple introduction to what epidemiology is, and how to make sense of epidemiology studies when people's health is on the line. With Mariya Voytyuk. Written, illustrated, narrated and filmed by Dr. Mariya Voytyuk RISK BITES Risk
How dangerous is dioxane in your drinking water?
How worried should you be if 1,4-dioxane gets into your drinking water? 1,4-dioxane is an industrial chemical used as a solvent and a stabilizer -- and in areas where there's environmental contamination, safety is an important question, especially as the substance is a probable human carcinogen. The US Environmental Protection Agency has conducted an extensive assessment of the risks of drinking 1,4-dioxane contaminated water. This week's risk bites takes a look at what this assessment means for the city of Ann Arbor, where there's significant 1,4-dioxane groundwater contamination.

In 1984 1,4- dioxane was detected by a University of Michigan School of Public Health graduate student in Third Sister Lake close to the company. 1,4-dioxane was subsequently discovered in private water supplies to the west of Ann Arbor in 1985. After nearly 30 years of environmental remediation and legal and community action, the area affected by the groundwater contamination continues to grow.

How do you know if the chemicals in the stuff you use and eat are safe? Only a small fraction of the thousands of chemicals in use today have been thoroughly tested for safety. Part of the problem is that how we test chemicals now is slow, expensive, and relies an awful lot on animal testing. How
