HALOCARBONS

Item #d95jan83

"Ozone Depletion and Global Warming Potentials of CF3I," S. Solomon (Aeron. Lab., NOAA, 325 Broadway, Boulder CO 80303), J.B. Burkholder et al., J. Geophys. Res., 99(D10), 20,929-20,935, Oct. 20, 1994.

Laboratory data used with a photochemical model showed that the lifetime of CF3I in the sunlit atmosphere is less than a day. Any iodine that reaches the stratosphere will be effective for ozone destruction, but the short lifetime limits transport to the stratosphere. Neither the ozone depletion potential nor the global warming potential represents a significant obstacle to CF3I use as a halon replacement.

Item #d95jan84

"Distribution of Emissions of Chlorofluorocarbons (CFCs) 11, 12, 113, 114 and 115 Among Reporting and Non-Reporting Countries in 1986," A. McCulloch, P.M. Midgley, D.A. Fisher, Atmos. Environ., 28(16), 2567-2582, Sep. 1994. (See Global Climate Change Digest, Nov.-Dec. 1994)

Item #d95jan85

"Increase in Atmospheric CHF2Cl (HCFC-22) over Southern California from 1985 to 1990," F.W. Irion (Dept. Chem. Eng., Calif. Inst. Technol., Pasadena CA 91125), M. Brown et al., Geophys. Res. Lett., 21(16), 1723-1726, Aug. 1, 1994.

The exponential column increase rate was (6.7 ± 0.5)% per yr. Derived a south-north interhemispheric ratio of (0.86 ± 0.08), by including column measurements over Antarctica. Uncertainty prohibits the use of CHF2Cl column measurements to infer either its lifetime or the global OH field.

Item #d95jan86

"The Natural Production of Chlorinated Compounds," G.W. Gribble (Dartmouth Coll., Hanover NH 03755), Environ. Sci. Technol., 28(7), 310A-319A, July 1994.

Reviews organochlorine compounds that are produced naturally by some plant and animal life, and by volcanic eruptions. Knowledge about natural organohalogen products is growing rapidly, and the first International Conference on Naturally Produced Organohalogens was held last year.
