Best of Power Hour: Dr. Edward Calabrese on the Science of Environmental Danger

On this week’s Power Hour “best of” episode, I talk to Dr. Edward Calabrese, professor of toxicology at the Department of Environmental Health Sciences in the School of Public Health at the University of Massachusetts at Amherst.

We discuss the linear no-threshold dose-response model, which regulatory agencies use to set pollution standards, and his findings about a more realistic “hormetic” response model that could improve regulatory standards and human health if adapted.
