HALOCARBONS: SOURCES AND DISTRIBUTION
"Global Production and Emissions of Bromochlorodifluoromethane and
Bromotrifluoromethane (Halons 1211 and 1301)," A. McCulloch (Environ.
Dept., ICI Chem. Ltd., Runcorn, Cheshire WA7 4QD, UK), Atmos. Environ.,
26A(7), 1325-1329, 1992.
Data were assembled from audited values submitted by producers within OECD
countries, and from estimates of production in the USSR and China. Annual
emissions of halons, calculated from the production figures and industrial
estimates of the annual percentages released, are generally consistent with
measured atmospheric concentrations.
"Naturally and Anthropogenically Produced Bromoform in the Kattegat,
a Semi-Enclosed Oceanic Basin," E. Fogelqvist (Oceanog. Lab., Swed. Meteor.
Hydrol. Inst., POB 2212, S-403 14 Göteborg, Swed.), M. Krysell, J.
Atmos. Chem., 13(4), 315-324, Nov. 1991.
Discusses the origin of bromoform in seawater, as well as possible sinks and
breakdown mechanisms. A bromoform budget calculated for the area between Sweden
and Denmark, where the input of bromoform from a power plant is significant,
shows biogenic and anthropogenic contributions to be locally comparable.
"Levels of Airborne Halocarbons at Urban and Mountain Forest Sites
in Germany and at the Atlantic Coast," W. Frank, H.J.C. Neves, H. Frank
(Univ. Tübingen, Inst. Toxikol., Wilhelmstr. 56, 7400 Tübingen, Ger.),
Chemosphere, 23(5), 609-626, 1991.
Concentrations of C1- and C2-halocarbons have been measured by automatic
sampling at two urban and three forest sites in Germany and on the Atlantic
coast of Portugal. Forest levels are higher than on the coast; urban levels are
10 to 100 times higher. The time variability of individual species are
"Distributions of Several Halogenated Hydrocarbons in the
Atmospheric Surface Layer above the Norway and Greenland Seas," G.T. Burova
(Central Aerol. Observatory), A.G. Katrick, E.A. Cayanova, Izvestiya, Atmos.
Ocean Phys., 25(10), 1989. (English Ed., pp. 827-828, May 1990.)
Presents measurements of Freon-11, chloroform, carbon tetrachloride and
tetrachloroethylene obtained by gas chromatography during cruises in the Norway
and Greenland seas, and discusses their temporal variability and dependence on
