• OF GENERAL INTEREST: OZONE DEPLETION

Item #d94mar6

"Better Protection of the Ozone Layer," M.K.W. Ko (Atmos. & Environ. Res. Inc., 840 Memorial Dr., Cambridge MA 02139), N.-D. Sze, M.J. Prather, Nature, 367(6463), 505-508, Feb. 10, 1994.

Because more and more chemicals, such as rocket fuel and pharmaceuticals, are turning out to be ozone-depleting, a more refined approach is needed for effective and equitable control. Makes specific recommendations for ways to extend international agreements to include chemicals whose applications and life-cycles are very different from the synthetic halocarbons already controlled by the Montreal Protocol. The goal is long-term protection of the ozone layer, based on scientific understanding of stratospheric ozone and the chemicals in question, avoiding capricious impacts on technological development.

Two related items in Science, 263(5151), Mar. 4, 1994:

"Fires, Atmospheric Chemistry and the Ozone Layer," R.J. Cicerone (Earth System Sci., Univ. California, Irvine CA 92717), 1243-1244. Provides a scientific perspective on the results published in the following article.

"Emission of Methyl Bromide from Biomass Burning," S. Manö, M.O. Andreae (M. Planck Inst. Chem., POB 3060, D-55020 Mainz, Ger.), 1255-1257. Because bromine is far more effective than chlorine at destroying stratospheric ozone, control of the pesticide methyl bromide is scheduled under the Montreal Protocol. Estimates based on laboratory measurements show that biomass burning is a major source of methyl bromide emissions, comparable to pesticide use and natural oceanic emissions.
