OZONE DEPLETION: UV IMPACTS

Item #d97jan41

"Estimates of Ozone Depletion and Skin Cancer Incidence to Examine the Vienna Convention Achievements," H. Slaper (Lab. Radiation Res., Natl. Inst. Public Health & Environ. Protect.-RIVM, POB 1, 3720 BA Bilthoven, Neth.), G.J.M. Velders et al., Nature, 384(6606), 256-258, Nov. 21, 1996.

Presents a new method of estimating future excess skin cancer risks, which is used to compare the effects of a "no restrictions" scenario with two restrictive scenarios proposed through the Montreal Protocol and the stricter Copenhagen amendments. The no-restrictions and Montreal Protocol scenarios would produce, respectively, a quadrupling and doubling of skin cancers by 2100. The Copenhagen amendments would produce a peak relative increase of about 10% by 2060.

Item #d97jan42

"Influence of the Greenhouse Effect on Human Health Through Stratospheric Cooling: Possible Increase in Acquired Immunodeficient Syndrome," K. Okamoto (Toyo Gakuen Univ., 1660 Hiregasaki, Nagareyama, Chiba 270-01, Japan), H. Tsushima, S. Tanimoto, World Resource Review, 8(3), 349-357, Sep. 1996.

Presents epidemiological evidence to support the hypothesis that cooling of the stratosphere by greenhouse gases increases stratospheric ozone destruction, and the resulting increase in exposure of humans to ultraviolet light could increase the incidence of AIDS.

Item #d97jan43

"Penetration of Biologically Active UV Radiation and Its Effects on Major Biological Processes in the Bering and Chukchi Seas," Yu.A. Izrael (Inst. Global Climate & Ecol., Rosgidromet & Russian Acad. Sci.), A.V. Tsyban et al., No. 10, 8-20, 1995.

Actinometric, meteorological, microbiological and hydrobiological measurements were made. Biologically active UV radiation can penetrate 5-20 m and 1-10 m, respectively, into the Bering and Chuckchi Seas. Primary production of organic matter was inhibited 30-80% in the 0-20 m layer. In the same layer bacterial destruction of organic matter was 10-50%, and in the Chukchi Sea, the effect was 40-70%.
