New chemical compounds are constantly being created to meet specific industrial applications and for human uses. Release of these compounds into the environment is inevitable and their contamination of natural resources, as well as their effect on human health, remain an important global ecological concern. Many compounds degrade in the presence of various natural processes, so there is a need to understand whether new compounds will persist in the environment or will eventually break down innocuously. "Natural Processes and Systems for Hazardous Waste Treatment" discusses the various natural processes for the attenuation and degradation of hazardous compounds and these processes' application in inexpensive natural systems. Major attenuation processes that are covered include: sorption and sequestration, biodegradation and assimilation processes, photo-processes, phyto-processes, oxidation-reduction, and physical processes. Extensive up-to-date references are presented, as are numerous illustrations, tables, and case studies. This book will serve as a reference for undergraduate or graduate students, as well as for practicing professionals.show more

In 2004 an amount of 187 tons of palladium has been sold in world market. The main demands were automotive catalyst (58%), electronics (14%), jewellery (14%) and dental practises (13%). Especially, the increasing use of palladium in catalytic converters is a reason for substantial research in this field. Emission, environmental distribution and possible health effects of pla- num have been summarized detailed in two recent books "Emissionen von Platinmetallen: Analytik, Umwelt- und Gesundheitsrelevanz" and "Anth- pogenic Platinum Group Emissions - Their Impact on Man and Envir- ment" published by Springer in 1999 and 2000 (Zereini & Alt (Eds)). But there is a clear lack of information concerning palladium. It is very imp- tant to condense the present state of research findings from emission to potential health risks for the environment and humans. Very important is the chapter about analytical determination of pal- dium, which shows clearly the problems of several analytical techniques. Some data published during the last decade have to be re-evaluated because of insufficient analytical techniques. Also the finding that palladium c- pounds are relatively soluble and mobile in environmental settings is a great issue for further investigations. I think it is the right time for such a comprehensive book about palladium research and I am sure that readers with different scientific background like chemists, biologists, geologists medical doctors e.g. will benefit very much from reading this book.show more

From the medical sheets in maternity wards to our death certificates, paper charts the course of our lives. Paradoxically, it spreads ideas and learning as well as thousands of tons of junk mail, yet our dependence on this material is damaging our planet and creating mountains of unnecessary waste. Mandy Haggith explores our society's obsession with paper, from its invention in China 2000 years ago to the millions of tonnes we now use every year. Following the paper trail around the world, Mandy discovers the human stories of those affected by the industry, from a Russian ecologist, a Finnish logger and Indonesian tribal leaders, to a Canadian publisher and a Vietnamese paper technologist. In the process, she uncovers the paper industry's dirtiest secrets and sets out simple, practical steps we can take to minimise our own personal use of 20 tonnes of paper over our lifetime.show more

Life on Earth emerged under anaerobic conditions. Many fundamental b- chemical and metabolic pathways evolved before the atmosphere contained oxygen. Today, anaerobic (anoxic) conditions in marine milieus are generally restricted to sediments and to basins isolated from oxygenated deep-sea cir- lation. Oxygen-de?cientorhypoxicconditionsarede?nedinoperationalterms. In speaking of the degree of O -de?ciency, the term hypoxic is usually de?ned 2 as ranging between 22 and 64?MofO , while suboxic refers to a range below 2 10?M, and anoxic is the complete absence of oxygen. Biologists commonly use the term hypoxia to describe the point at which animals suffocate. But the papers presented in this book deal with the whole range of oxygen-de?cient conditions, and the de?nitions some authors have used here may vary. Enhanced oxygen consumption by decomposition of organic matter and slow downward mixing and diffusion of dissolved oxygen from the surface waters can lead to oxygen de?ciency in the water column in highly productive waters, forming the Oxygen Minimum Zone (OMZ).Bottom waters of coastal upwelling regions are frequently exposed to hypoxic (suboxic) or anaerobic conditions owing to extremely high primary productivity. The development of these conditions represents an acute perturbation to ecological dynamics and ?sheries. Inthepast,anoxicconditionsinthewatercolumnmayhavedeveloped morereadily.

People and the Environment: Approaches for Linking Household and Community Surveys to Remote Sensing and GIS appeals to a wide range of natural, social, and spatial scientists with interests in conducting population and environment research and thereby characterizing (a) land use and land cover dynamics through remote sensing, (b) demographic and socio-economic variables through household and community surveys, and (c) local site and situation through resource endowments, geographical accessibility, and connections of people to place through GIS. Case studies are used to examine theories and practices useful in linking people and the environment. We also describe land use and land cover dynamics and the associated social, biophysical, and geographical drivers of change articulated through human-environment interactions.show more

Rather than the 25 to 30 chapters found in most environmental science textbooks, the authors have limited Principles of Environmental Science: Inquiry and Applications to 16 chapters--perfect for the one-semester, non-majors environmental science course. True to its title, the goal of this concise text is to provide an up-to-date, introductory view of essential themes in environmental science along with offering students numerous opportunities to practice scientific thinking and active learning. show more
