- Abstract
- The decision to phase out the use of halons due to their role in stratospheric ozone loss has led to accelerated efforts to find "environmentally friendly" replacements. Thus, the need has arisen for an efficient means to evaluate the large suite of proposed alternatives for environmental acceptability. In particular, this means obtaining one of the most important pieces of information relating to the atmospheric fate of volatile species: the reactivity towards the hydroxyl radical. The reaction with tropospheric OH typically controls the atmospheric lifetime of many substances and is thus a starting point in the evaluation of its acceptability. Carrying out laboratory measurements on all the proposed replacements is an expensive proposition, made worse by the fact that many of the compounds would have to be synthesized and provided in sufficient purity for kinetic measurements. Clearly, the development of screening tools capable of predicting the properties important in assessing environmental persistence would be beneficial to this process.
