Book Description
The study of estuaries and coasts has seen enormous growth in recent years, since changes in these areas have a large effect on the food chain, as well as on the physics and chemistry of the ocean. As the coasts and river banks around the world become more densely populated, the pressure on these ecosystems intensifies, putting a new focus on environmental, socio-economic and policy issues. Written by a team of international expert scientists, under the guidance of Chief Editors Eric Wolanski and Donald McClusky, the Treatise on Estuarine and Coastal Science, Ten Volume Set examines topics in depth, and aims to provide a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Most up-to-date reference for system-based coastal and estuarine science and management, from the inland watershed to the ocean shelf Chief editors have assembled a world-class team of volume editors and contributing authors Approach focuses on the physical, biological, chemistry, ecosystem, human, ecological and economics processes, to show how to best use multidisciplinary science to ensure earth's sustainability Provides a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Features up-to-date chapters covering a full range of topics

Book Description
Should the production and use of chlorine and all chlorinated organic compounds be halted, in view of their adverse effects on the environment and human health? Those in favour argue that certain chlorinated compounds (PCBs, DDT, CFCs, etc.) have large negative environmental effects. The use of chlorine in disinfectants leads to the production of chloroform, while bulk products (PVC) contribute to the production of chlorinated dibenzo-p-dioxins and dibenzofurans when they are burned. Those against argue that chlorine and many chlorinated compounds are essential in the control of human health (the prevention of disease transmitted through drinking water that has not been disinfected), and that chlorinated compounds are indispensable intermediates in many production processes, representing a vast economic value. But such discussions often ignore the fact that Nature contributes significantly to the production of chlorinated organic compounds. More than 1000 such compounds are known, and their contribution to the biogeochemical cycling of chlorine is underestimated. Chlorine is organically bound in large quantities to humic materials, and natural production mechanisms are known for low molecular weight compounds (methyl chloride, chloroform, chlorinated dibenzo-p-dioxins and dibenzofurans). The role of these compounds in the environment is largely unknown. Naturally-Produced Organohalogens gives a complete overview of the present state of knowledge on the subject, giving a much needed balance to the argument sketched out above.

Book Description
Knowledge of thc chemical behavior of trace compounds in the atmosphere has grown steadily, and sometimes even spectacularly, in recent decades. These developments have led to the emergence of atmospheric chemistry as a new branch of science. This book covers all aspects of atmospheric chemistry on a global scale, integrating information from chemistry and geochemistry, physics, and biology to provide a unified account. For each atmospheric constituent of interest, the text summarizes the principal observations on global distribution, chemical reactions, natural and anthropogenic sources, and physical removal processes. Coverage includes processes in the gas phase, in aerosols and c1ouds, and in precipitation, as well as biogeochemical cycles and the evolution of the atmosphere. Chemistry of the Natural Atmosphere, Second Edition, will serve as a textbook for senior undergraduate and graduate courses, and as an essential reference for atmospheric chemists, meteorologists, and anyone studying the biogeochemical cycles of trace gases.* Updated extensively from the highly respected first edition * Treats the global-scale chemistry and distribution of atmospheric trace constituents * Emphasizes observations and their interpretation* Provides background on transport and reaction kinetics for interpretation of observational data* Includes chemistry in the gas phase and in aerosols and clouds* Details chemical reaction pathways for the most important trace constituents* Describes pertinent biogeochemical cycles* Written by an author with more than 40 years of research experience in atmospheric chemistry

Book Description
Bioenvironmental Issues Affecting Men's Reproductive and Sexual Health is structured into two parts related to men's reproductive and sexual health with eight sections designed to enable a logical flow of such knowledge. The book is focused on the biology of key organs involved in male reproduction and the environmental influences affecting their functions with particular emphasis on clinical aspects. Individual chapters within the book range from basic to translational aspects, but all hold clinical relevance. This is an essential reference for those working and learning in the field of human reproduction, reproductive toxicology and environmental influences on reproductive and sexual health. - Brings together the leading authorities working in the field of male reproduction and sexual health and how the environment affects these issues - Provides guidelines and reference values of various reproductive hormones, semen parameters, inclusion/exclusion criteria for clinical trials - Discover the most efficient methods by which to design clinical protocols for sperm safety studies and reproductive toxicology trials
