- OZONE-DEPLETING SUBSTANCES
cleared: A comprehensive study by U.S. researchers shows that
hydrofluorocarbon substitutes for CFCs do not destroy
stratospheric ozone. (See Ravishankara paper in Prof. Pubs./Gen.
Interest, and news articles in Chem. Eng. News (pp. 5-6,
Jan. 10), Intl. Environ. Rptr. (p. 9, Jan. 12), Chem.
& Industry (p. 45, Jan. 17), and New Scientist (p.
15, Feb. 5). Independent of this development, Bosch, a leading
manufacturer of refrigerators, decided to abandon HFCs for
chemicals like pentane and isobutane (ibid., p. 4).
Final HCFC exemptions were published by the U.S.
Environmental Protection Agency from the ban on non-essential
goods made with hydrochlorofluorocarbons. They include portable
fire extinguishers and aircraft cleaning fluids. See Intl.
Environ. Rptr., pp. 16-17, Jan. 12, or Federal Register,
Dec. 30, p. 69638.
Europe's CFC Phaseout 11 Months Away, Refrigeration Industry
Starts to Panic," Global Environ. Change Rep., pp.
1-3, Feb. 11. A feature report on how Europe's refrigeration
industry must reduce its extensive use of CFCs to zero in the
next 11 months. (This topic is also discussed in Intl.
Environ. Rptr., pp. 167-168, Feb. 23.)
to Help Reduce Military Use of Ozone-Depleting Compounds," ibid.,
pp. 4-5. A NATO meeting on the role of the military in ozone
protection (Brussels, Jan. 1994) concluded that much progress has
been made, but significant challenges remain for some critical
Phase-Out Moves Quickly," A. Newman, Environ. Sci. &
Technol., pp. 35A-37A, Jan. Speakers at the 1993
International CFC and Halon Alternatives Conference
(Washington, D.C., Oct. 1993) discussed how the phase-out in
general is proceeding faster and at less cost than expected.
