Estimates of steady-state reductions in stratospheric ozone due to continued releases of two chlorofluorocarbons (11 and 12) at 1977 rates in the absence of other perturbations are lower than 1979 estimates by a factor between two and three. Current models suggest the steady-state reduction will lie between 5 and 9 percent. The association of nonmelanoma skin cancers with ultraviolet-B radiation suggests that reductions in stratospheric ozone will result in increases of these cancers. Exposure to ultraviolet-B also has been shown to adversely affect the immune response system; further research is needed to determine the importance of this finding for understanding photocarcinogenesis.
