Ozonation in atmospheric chemistry

Thus a number of catalytic reactions are associated with the re-formation of 02 already indicated in equation (5). In other words, a halogen, or any other atom which attacks ozone, always reappears as a result of the reaction between its oxide and atomic oxygen, and hence there is a permanent cycle leading to the destruction of ozone. In atmospheric chemistry, therefore, it is important to find out how these constituents appear, and to assess their importance. 

The role of ozone in atmospheric chemistry is discussed in Section 11.8.
