Abstract
Prior analyses of chlorocarbons and their effects on stratospheric ozone have primarily concentrated on examining potential perturbations from two chlorofluorocarbons, CFCℓ3 (CFC‐11) and CF2Cℓ2 (CFC‐12). The purpose of this study is to provide an updated theoretical analysis of the potential effect on ozone due to past and future chlorocarbon emissions. To assess the overall impact from chlorinated emissions on the ozone layer, all chlorocarbons presently thought to be of likely concern are examined. A broad spectrum of scenarios is evaluated in order to provide an envelope including conceivable changes in future chlorocarbon emissions. Results indicate that CFCℓ2CF2Cℓ (CFC‐113), CH3CCℓ3, and CCℓ4 could contribute significantly to predicted changes in total ozone based on their current emission rates.
