- OF GENERAL INTEREST: OZONE DEPLETION
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.
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
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.
