Most of us have little idea what chemicals are
in the things that we buy. We think government
safeguards us, regulating things like lead in toys. That
much is true. But what about the more than 80,000
chemicals used in manufacturing today? As it turns out,
almost all of them are completely unstudied and unregulated. Guest: Dr. Mike Wilson, PhD, environmental health scientist with the School of
