Stranica 253 - NSF-coordinated expedition to the McMurdo station in Antarctica last year was exceptionally successful in increasing our understanding of the Antarctic ozone hole. In conjunction with other experiments, this ground based effort demonstrated the recurrence of the ozone hole, the altitude over which ozone was depleted, that chlorine and nitrogen chemistry was highly perturbed relative to that observed at mid-latitudes, and that the solar cycle theory is an unlikely explanation. However, the McMurdo...
Stranica 62 - the Administrator shall propose regulations for the control of any substance, practice, process, or activity (or any combination thereof) which in his judgment may reasonably be anticipated to affect the stratosphere, especially ozone in the stratosphere, if such effect in the stratosphere may reasonably be anticipated to endanger public health or welfare
Stranica 71 - Major rule" means any regulation that Is likely to result in: (1) An annual effect on the economy of $100 million or more: (2) A major increase in coats or prices for consumers. Individual industries. Federal. State, or local government agencies, or geographic regions: or (3) Significant adverse effects on competition, employment investment, productivity. Innovation, or on the ability of United States-based...
Stranica 211 - ... two out of three cultivars are sensitive to UV-B. 20. Aquatic organisms, particularly phytoplankton, zooplankton, and the larvae of many fishes, appear to be susceptible to harm from increased exposure to UV-B radiation because they spend at least part of their time at or near surface waters. However, additional research is needed to better understand the ability of these organisms to mitigate adverse effects and any possible implications of changes in community composition as more susceptible...
Stranica 15 - Mr. Chairman and members of the committee, I very much appreciate the opportunity to appear before you today In support of four public works projects in my district, the 13th Congressional District of Ohio.
Stranica 253 - The concept of mixing at the region of sharp latitudinal gradient is important, since it has the potential to supply nitrogen oxides which would tend to decelerate the chlorine chemistry. The meteorology is thus important in the termination phase as well as in the initiation phase. 8) Can we quantitatively separate the contributions of chemistry and meteorology to the formation of the ozone hole?
Stranica 137 - SETLOW, RB, 1974. The wavelengths in sunlight effective in producing skin cancer: a theoretical analysis.
Stranica 56 - ... relationship between cutaneous malignant melanoma and UV-B radiation Is a complex one. However, recent studies, some of which are financially supported by the Agency, suggest that UV-B radiation plays an Important role In causing melanoma. Studies have also demonstrated that UV-B radiation can suppress the Immune response system In animals and possibly humans. While UV-B Induced Immune suppression has been linked to herpes virus Infections and I el shman I as I s , Its possible Impact on other...
Stranica 252 - Mr. Chairman and members of the committee. What I would like to do is to submit my statement and then touch on the highlights in my oral presentation rather than reading it.
Stranica 71 - Major rule" means any regulation that is likely to result in: (1 ) An annual effect on the economy of $100 million or more; (2) A major increase in costs or prices for consumers, individual industries, Federal, State, or local government agencies, or geographic regions; or (3) Significant adverse effects on competition, employment, investment, productivity, innovation, or on the ability of United States-based enterprises to compete with foreign-based enterprises in domestic or export markets.
