Chapter 18

1. Know the major portions of the earth's atmosphere and describe each one.
2. Explain the formation of ozone, both in the troposphere and stratosphere. Be able to talk about how ultraviolet radiation and CFC's interact with it.
3. Know 'high points' about water pollution and how various human activities effect it.
4. Know the basic terminology about toxic chemicals (LD50, chronic toxicity...) and how we measure it.
5. Define what cancer is in simple terms, and how we determine if something is cancer causing.
6. What is an organic pollutant?
7. Know many of the reasons why Hg, Cd, and Pb are very very very bad for you and the rest of the ecosystem.
8. Be able to explain global warming using simple terms and concepts.

Problems:

There are really no good problems for this chapter, mostly because the problems that ARE there are mostly rudimentary calculations, which is not the emphasis of this material.

- The exam will have questions directly related to the 8 points given above. They will be of essay type, and require you to not only remember a laundry list of facts, but to put them together is some cohesive answer.
