Lecture 7-Questions
1) Provide the reactions of ozone’s natural cycle?
2) Provide the reactions of the ozone destruction from CFCs.
3) What is the problematic feature of the chlorine/bromine atoms as catalysts of ozone destruction.
4) Why Freon was characterized asmiracle compound”?
5) The Montreal Protocol: Objectives and factors for its success.
6) Why Antarctica is much more vulnerable to ozone depletion?
7) What is the causal link between volcanic eruptions and stratospheric ozone depletion?
8) Which are the major sources of sulfur dioxide to the atmosphere?
9) Do we have evidence of ozone depletion in places other than Antarctica?
10) Which factors characterize the variability of the UV radiation?
11) It is expected that the increased UV radiation will increase photochemical production of ozone at
lower levels (in the troposphere); why do we still observe a decreasing trend in total column ozone?
12) Biological effects of increased UV. Which are the most common forms of skin cancer? Which are
the effects of increased UV radiation on plankton?
13) What is the role of CFCs on the climate change?
14) Provide other ozone-depleting pollutants?
15) Manmade chlorine is insignificant compared to natural sources: do you agree?

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!
