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.

Book Description
This book, first published in 2000, provides a comprehensive, multidisciplinary review of UV radiation effects in the marine environment. It is aimed at researchers and graduate students in photobiology, photochemistry and environmental science. It will also be useful as a supplementary text for courses in oceanography, climatology and ecology.

Book Description
Aquatic and Surface Photochemistry provides a broad overview of current research in the emerging field of environmental aquatic and surface photochemistry. Selected reviews and current research articles are blended to provide an in-depth treatment of various aspects of this research area. The first part of the text deals with photochemistry in the environment, covering recent research on the following topics: aquatic photochemistry of organic pollutants and agrochemicals, photochemical cycling of carbon and transition metals (especially iron), photochemical formation of reactive oxygen species in natural waters, photoreaction in cloud and rain droplets, and photoreactions on environmental surfaces (soil, ash, metal, oxide). The second part provides discussions and data on both heterogeneous photocatalytic and homogeneous processes, with topics ranging from applications to mechanistic studies. These chapters illustrate the wide diversity of pollutant classes that are degradable by photochemical techniques and the effects of various reaction conditions on the rates and efficiency of the techniques. Current kinetic studies are presented, which provide new information about the role of adsorption and the nature of the reactive oxidizing species that mediate these photoremediation processes.This book will interest civil, chemical, and environmental engineers, as well as chemists, soil scientists, geochemists, and atmospheric chemists.

Book Description
This is the first book to provide measurements of greenhouse gases from both aquatic and terrestrial environments as well as from hydroelectric reservoirs. This monograph not only presents the state-of-the-art techniques for measuring the emissions of greenhouse gases, but also demonstrates the mechanisms or processes leading to the emissions of greenhouse gases. It offers the reader a synthesis of what we understand of GHG emission after 12 years of research in boreal ecosystems, the estimations of gross and net emissions from hydroelectric reservoirs, the impact of hydroelectric reservoirs on climate change, as well as a comparison of the different alternatives for producing energy in relation to GHG emissions.

Book Description
Since the realisation that the ozone layer protecting the earth is suffering massive depletion, atmospheric science has been increasingly in the spotlight. It is recognised that we need to increase our knowledge and understanding of the likely impact that increases in UV-B radiation will have on life on earth. Charting research that encompasses the changing distribution of atmospheric ozone, changes in UV-B radiation and the consequent effects on photochemistry and biological systems in the aquatic and terrestrial environments, Causes and Environmental Implications of Increased UV-B Radiation draws together experts from the international community. Also included is a discussion of the emotive and highly topical subject of skin cancer as related to increased UV-B radiation. As an up-to-date and authoritative summary of the state of this highly complex science, this book will be welcomed by all practitioners and researchers in the field.
