A Guide to Information on Greenhouse Gases and Ozone Depletion
Published July 1988 through June 1999
FROM VOLUME 7, NUMBER 3, MARCH 1994
Radiation and Ozone Effects on Growth, Yield, and Photosynthesis
of Soybean," J.E. Miller (ARS, USDA, 1509 Varsity Dr.,
Raleigh NC 27606), F.L. Booker et al., J. Environ. Qual., 23(1),
83-91, Jan.-Feb. 1994.
Chamber experiments imply that tropospheric O3 is a much
greater threat to soybean production than predicted levels of
of Solar Irradiation on Motility and Pigmentation of Three
Species of Phytoplankton," S. Gerber, D.-P. Häder (Inst.
Bot. & Pharm. Biol., Friedrich Alexander Univ., Staudtstr. 5,
D-8520 Erlangen, Ger.), Environ. Exper. Bot., 33(4),
515-521, Oct. 1993.
Studies on two Cryptomonas species and Euglena
gracilis showed that slightly increased UV-B levels may have
severe effects on phytoplankton populations.
in Photochem. & Photobiol., 58(4), Oct. 1993:
"Effects of Arctic Ozone Depletion and Snow on UV
Exposure in Finland," K. Jokela (Ctr. Radiation &
Nuclear Safety, POB 268, FIN-00101 Helsinki, Fin.), K.
Leszczynski, R. Visuri, 559-566. The combined effect of ozone
depletion and snow reflection in winter had no significant effect
on annual exposure because ozone levels returned to normal before
the UV increased to biologically significant levels.
"Ultraviolet Radiation in Antarctica: Inhibition of
Primary Production," O. Holm-Hansen (Polar Res. Prog.,
Scripps Inst. Oceanog., La Jolla CA 92093), E.W. Helbling, D.
Lubin, 567-570. Calculations that account for the extent and
duration of low stratospheric ozone concentration from
September-November indicate that the decrease in total annual
primary production due to enhanced UV-B would be £0.20%.
Effective in Induction of Malignant Melanoma," R.B. Setlow
(Biol. Dept., Brookhaven Natl. Lab, Upton NY 11973), E. Grist et
al., Proc. Natl. Acad. Sci., 90(14), 6666-6670,
July 1993. (See GCCD, Oct. 1993.)
Balance and UV-B Sensitivity of Soybean: A Field
Experiement," M.M. Caldwell (Dept. Range Sci., Utah State
Univ., Logan UT 84322), S.D. Flint, P.S. Searles, Plant, Cell
& Environ., 17(3), 267-276, Mar. 1994.
Results indicate difficulties in extrapolating from UV-B
experiments conducted in glasshouse or growth cabinet conditions
to plant UV-B sensitivity in the field.
Role of Ultraviolet-B in Controlling Bacterioplankton Growth in
the Surface Layer of the Ocean," G.J. Herndl (Inst. Zool.,
Univ. Vienna, Althanstr. 14, A-1090 Vienna, Austria), G.
Müller-Niklas, J. Frick, Nature, 361(6414),
717-719, Feb. 25, 1993.
Field measurements show that elevated UV-B may reduce
bacterial activity, which could lead to increased labile
dissolved organic matter.
Depletion and Skin Cancer: Attempted Assessment of Future
Risks," F.M. Schaart (Free Univ. Berlin, Hindenburgdamm
30/W-1000 Berlin 45, Ger.), C. Garbe, C.E. Orfanos, Hautarzt, 44(2),
63-68, Feb. 1993. In German.
Estimates an additional 3000-5000 non-melanomas and 120-400
melanomas per year in Germany during the next few decades due to
Effects of Ozone Depletion on the Global Carbon Cycle," T.H.
Peng (Environ. Sci. Div., Oak Ridge Natl. Lab., Oak Ridge TN
37831), Radiocarbon, 34(3), 772-779, 1992.
Evaluates possible effects through lowered marine
productivity, using box models of the oceans based on the
distribution of bomb-produced C14.
