摘要：

The results of an audited production and use survey for chlorodifluoromethane (HCFC 22) for the years 1980-1991 are reported. Annual production figures for 1970-1979 have also been collected. The time delays for release to the atmosphere for the various uses of this commercial gas are estimated in order to calculate annual emissions. Calculated atmospheric concentrations and trends are compared with available measurements. Uncertainties in calculated -parameters are examined relative to assumptions made in the analysis.
