Book Description
The workshop was held to review the current Canadian research on the effects of increased UV-B radiation on various receptors; to determine the present status of effects research; to make projections regarding likely environmental effects; and to make recommendations on a short-term course of action. After the workshop, the authors were invited to provide a series of short statements under the general headings of what is known, what might happen, and what further information is needed. The report is a compilation of the authors' responses with an executive summary, covering stratospheric ozone depletion; effects of UV-B on vegetation, aquatic systems, and animals; and future actions for plants and agricultural crops, aquatic systems, animals, and awareness.

Book Description
Current phase-out schedules of the production and emission of CFC's indicate that chlorine loading in the stratosphere is not yet at its maximum. The recovery of stratospheric ozone is estimated to take time and ele vated levels of UV-B radiation are expected to occur throughout most of the next century. Despite numerous physiological studies of UV-B effects on plants, often grown in climate chambers, knowledge of UV-B effects on organisms and processes in natural aquatic or terrestrial ecosystems is poor. Currently it appears that UV-B radiation is not just an environmental stress' factor to plants. In various ways, which are incompletely understood, UV-B affects a wide range of physiological and ecological processes. Remarkably, recent field studies indicate that enhanced UV-B does not markedly affect photosynthesis, growth and primary production, but rather interferes with plant morphogenesis and plant and ecosystem functions relating to the secondary metabolism. This special issue and book UV-B and Biosphere is an attempt to cover this range and to report the progress made in the research of ecological effects of enhanced solar UV-B radiation. The papers in this book formed the basis of an international workshop entitled' UV-B and Biosphere' , December 15-18, 1995, in Wageningen, The Netherlands. A first reaction of Hans de Boois on the number of papers and sessions scheduled from Friday to Sunday morning was: far too many.

Book Description
Annotation While the enlarging hole in the Antarctic ozone layer is inherently a fascinating phenomena, we also need to understand the environmental hazard against which we are counting on stratospheric ozone to protect us: ultraviolet radiation. In six papers, contributors summarize what is known about the effects of the UV-B portion of the spectrum (e.g. on skin cancer), and assess future trends. Hester is a chemistry professor with the U. of York. Harrison is professor of environmental health at the U. of Birmingham. Distributed in the US by Springer-Verlag. Annotation c.
