EXPERIMENTATION

Risk

• Chemo phobia – irrational fear of chemicals• Why?

– Irresponsible companies– Media

• Love Canal, NY and Times Beach, Missouri

• Fear of some chemicals is good, but not all– Dihydrogen monoxide (DHMO)

Acceptable Risk?

• Smoking vs. living by a nuclear power plant

• Fear of flying

• Can control vs. can’t control

• Can’t avoid all risk

Legislating Risk

• Risk based laws – FDA

• Balancing laws– Clean Air Act– Safe Drinking Water Act

• Technology based laws– Proposition 65 in California

Controversy

• Animal experiments– Ethical?– Depend on how done?

• Cold fusion

• Greenhouse effect

• Cholesterol
