Summary
Reactive chemical species are generated as a consequence of light absorption in the environment; including the hydroxyl radical, singlet oxygen, carbonate radicals, and many more. Similar chemicals are also used in treatment engineering, for example processes involving ozone. These cases typically result in the introduction of oxidants and their presence can be understood by considering their rates of formation and destruction. Knowing the concentrations of such reactive species, one can calculate their rates of reaction with organic compounds in both gaseous and solution phases. The structure-reactivity method of Atkinson and colleagues for estimating the rate constants of hydroxyl radical oxidizing gas-phase organic molecules is described to illustrate how both old and new substances can be assessed for their reactivities.
