Book Description
The changes in ground-level UV radiation that accompany changing cloud cover and stratospheric ozone levels may have serious consequence for numerous biological and geochemical cycles that are critically important to the well-being of the biosphere. Moreover, because carbon dioxide, nitrous oxide, methane, halocarbons, carbon monoxide and carbonyl sulfide all have natural sources and sinks in the biosphere, alterations of the biogeochemical cycles could introduce significant positive or negative feedbacks to the atmospheric concentrations of these important trace gases. To better assess the possible ramifications of changing UV levels on biogeochemical dynamics, this workship assembled a diverse group of experts, including atmospheric chemists and physicists and aquatic chemists, biochemists and biologists. Participants were asked to help identify and more clearly define: i) the potential effects of climate change on ground level solar UV (and visible) radiation, ii) the impacts of solar UV radiation on geochemical processes in aquatic systems, iii) the effects of solar UV radiation on biological processes, with emphasis on the possible effects of enhanced UV-B (280-320 nm) radiation. Participants were asked to discuss experimental and theoretical approaches to better characterize and model these processes on both regional and global scales. Questions that were addressed at the workshop included. Keywords: Remote detectors; Radiative transfer; Atmospheric chemistry. (kt).
UV Effects in Aquatic Organisms and Ecosystems
Author: E Walter HelblingPublisher: Royal Society of Chemistry
ISBN: 1847552269
Category : Science
Languages : en
Pages : 600
Book Description
This book offers extensive coverage of the most important aspects of UVR effects on all aquatic (not just freshwater and marine) ecosystems, encompassing UV physics, chemistry, biology and ecology. Comprehensive and up-to-date, UV Effects in Aquatic Organisms and Ecosystems aims to bridge the gap between environmental studies of UVR effects and the broader, traditional fields of ecology, oceanography and limnology. Adopting a synthetic approach, the different sections cover: the physical factors controlling UVR intensity in the atmosphere; the penetration and distribution of solar radiation in natural waters; the main photochemical process affecting natural and anthropogenic substances; and direct and indirect effects on organisms (from viruses, bacteria and algae to invertebrate and vertebrate consumers). Researchers and professionals in environmental chemistry, photochemistry, photobiology and cell and molecular biology will value this book, as will those looking at ozone depletion and global change.

Effects of Increased Ultraviolet Radiation on Global Ecosystems

Book Description
The inspiration for this monograph derived from the realization that human technical capacity has become so great that we can, even without malice, substantially modify and damage the gigantic and remote outer limit of our planet, the stratosphere. Above the atmosphere of our ordinary experience, the stratosphere is a tenuous layer of gas, blocked from rapid exchange with the troposphere, some twenty kilometers above the surface of the earth, seldom reached by humans, and yet a fragile shell which shields life on earth from a band of solar radiation of demonstrable injurious potential. It is immediately obvious that if stratospheric ozone were reduced and consequently the intensity of solar ultraviolet radiation reaching the earth's surface were increased, then human skin cancer, known to be related to solar ultraviolet exposure, would also be increased. But how does one even begin to estimate the impact of changed solar ultraviolet radiation on such a diverse. interacting, and complex ecosystem as the oceans? Studies which I conducted in Iceland focused on this question and were noted to the Marine Sciences Panel of the Scientific Affairs Committee of NATO by Professor Unnsteinn Stefansson, leading to a request to investigate the possibility of organizing a NATO sponsored Advanced Research Institute on this topic.
Environmental UV Radiation: Impact on Ecosystems and Human Health and Predictive Models
Author: Francesco GhettiPublisher: Springer Science & Business Media
ISBN: 9781402036965
Category : Medical
Languages : en
Pages : 306
Book Description
This publication originates from the NATO Advanced Study Institute on Environmental Radiation: Impact on Ecosystems and Human Health and Predictive Models, held in Pisa, Italy, in June 2001. The book offers not only basic information on the action mechanisms of UV radiation on ecosystems and various biological systems, but also a picture of the possible scenarios of the long-term global increase of environmental UV radiation, with emphasis on the research aspects aimed at the proper quantitative assessment of risk factors and the formulation of reliable predictive models. The purpose of the authors is to present a critical discussion on how changes in UV radiation will affect ecosystems and the biological processes needed to sustain life on Earth and to provide useful hints for future actions of governmental and international agencies, as well as non-governmental organizations. The book is structured in four sections: the first one is devoted to a general overview of the consequences of ozone depletion and to the basic concepts of radiation measurements and monitoring; the other three sections are devoted to the effects on plants, aquatic ecosystems and human health.
