Existing theoretical calculations and atmospheric measurements have indicated that the halocarbons CFCl/sub 3/ and CF/sub 2/Cl/sub 2/ have sufficiently long atmospheric lifetimes that, although they are produced and released into the atmosphere at the surface, they are primarily decomposed in the stratosphere photochemical processes. The chlorine atoms relesed by this decomposition process can participate in chlorine catalytic mechanisms for destroying stratospheric ozone. The possible depletion of the stratospheric ozone layer by such sources could have significant biological and agricultural impacts because of the sensitivity of living organisms to the increased ultraviolet irradiation that would accompany a decrease in the stratospheric ozone shield. This study uses the LLNL one-dimensional transport-kinetics model of the troposphere and stratosphere to examine the relative efficiency of a number of compounds for potentially reducing stratospheric ozone concentrations.
