DQ2 “Toxic Baby” and the Risk Assessment Process

Think about the human health risk assessment process we have learned about this week, which is used to determine potential risks to human health resulting from the exposure to chemicals in the environment. You also watched the TED Talk “Toxic Baby” with Tyrone Hayes and Penelope Jagessar Chaffer.

First, briefly answer the following question: What was the most surprising or interesting new thing you learned from this TED Talk? Have you heard of the issues discussed in this talk previously?

Then, briefly research one toxic chemical that we are, or may be, exposed to. It can be a chemical discussed in the TED Talk or any other toxic chemical that you have heard of or that interests you. Answer one of the following questions, using the toxin you selected as an example to support your answer:

What happens in the hazard identification stage?

What happens during the dose-response assessment?

What happens during the exposure assessment?

What happens in the risk characterization stage? How is the risk “characterized”?

What is the difference between non-cancer risk assessment and cancer-risk assessment?

What is the difference between risk assessment and risk management?

Please choose a toxin not yet described by other students and indicate it in the header of your post. As always, remember to document any sources you have used, including our course materials.
