Ecotoxiclogical risk from multiple stressors covers any situation where org- isms are exposed to a combination of environmental stressors. These include physical and chemical pollutants as well as other stressors such as parasites and environmental impact (e. g. , climate change or habitat loss). The combi- tion of stressors can result in increased risk to organisms (either additive or synergistic effects) or decreased effects (protective or antagonistic effects). The multiple stressor challenge is an international, multi-disciplinary problem requiring an international, multi-disciplinary approach. The c- rent approach to multiple stressors is to examine one stressor at a time and assume additivity. Little work has been done on combinations of stressors such that potential interactions can be determined. The problem is very complex. Multiple stressors pose a whole spectrum of challenges that range from basic science to regulation, policy and gove- ance. The challenges raise fundamental questions about our understanding of the basic biological response to stressors, as well as the implications of those uncertainties in environmental risk assessment and management. In addition to the great breadth, there is also great depth in the research ch- lenges, largely due to the complexity of the issues. From a basic science point of view, many of the mechanisms and processes under investigation are at the cutting edge of science — involving new paradigms such as genomic ins- bility and bystander effects.

This book presents a comprehensive overview on origin, structure, properties, modification strategies and applications of the biopolymer lignin. It is organized into four themed parts. The first part focuses on the analysis and characterization of the second most abundant biopolymer. The following part is devoted to the biological aspects of lignin such as biosynthesis and degradation. In the third part, chemical modification strategies and the preparation of composites as well as nano- and microparticles are discussed.The final part addresses the industrial application of lignin and its derivatives, as well as lignin materials. The usage for synthesis of biofuels, fine chemicals and in agriculture and food industry is covered. This book is a comprehensive source for researchers, scientists and engineers working in the field of biopolymers as well as renewable materials and sources.

Chemical Analysis of Food: Techniques and Applications reviews new technology and challenges in food analysis from multiple perspectives: a review of novel technologies being used in food analysis, an in-depth analysis of several specific approaches, and an examination of the most innovative applications and future trends. This book won a 2012 PROSE Award Honorable Mention in Chemistry and Physics from the Association of American Publishers. The book is structured in two parts: the first describes the role of the latest developments in analytical and bio-analytical techniques and the second reviews the most innovative applications and issues in food analysis. Each chapter is written by experts on the subject and is extensively referenced in order to serve as an effective resource for more detailed information. The techniques discussed range from the non-invasive and non-destructive, such as infrared spectroscopy and ultrasound, to emerging areas such as nanotechnology, biosensors and electronic noses and tongues. Important tools for problem-solving in chemical and biological analysis are discussed in detail. - Winner of a PROSE Award 2012, Book: Honorable Mention in Physical Sciences and Mathematics - Chemistry and Physics from the American Association of Publishers - Provides researchers with a single source for up-to-date information in food analysis - Single go-to reference for emerging techniques and technologies - Over 20 renowned international contributors - Broad coverage of many important techniques makes this reference useful for a range of food scientists

Halophytes are those plant species that can tolerate high salt concentrations. There are diversified species of halophytes suited for growth in various saline regions around the world, e.g. coastal saline soil, soils of mangrove forests, wetlands, marshlands, lands of arid and semiarid regions, and agricultural fields. These plants can be grown in soil and water containing high salt concentrations and unsuitable for conventional crops, and can be good sources of food, fuel, fodder, fiber, essential oils, and medicine. Moreover, halophytes can be exploited as significant and major plant species for the desalination and restoration of saline soils, as well as phytoremediation. This book highlights recent advances in exploring the unique features of halophytes and their potential uses in our changing environment.

The WWDR 2014 on Water and Energy is now an annual and thematic report with a focus on different strategic water issues each year. It is shorter in the order of 100 pages with a standardized structure and data and case studies annexes related to the theme. The WWDR 2014 will be launched during the main World Water Day celebrations in Tokyo, Japan on 21 March 2014. Water and energy are closely interconnected and highly interdependent. Trade-offs need to be managed to limit negative impacts and foster opportunities for synergy. Water and energy have crucial impacts on poverty alleviation both directly, as a number of the Millennium Development Goals depend on major improvements in access to water, sanitation, power and energy sources, and indirectly, as water and energy can be binding constraints on economic growth the ultimate hope for widespread poverty reduction. This fifth edition of the United Nations World Water Development Report (WWDR 2014) seeks to inform decision-makers

Humans first used carbon as chars from firewood in ritual paintings and primitive metallurgical processes. Natural forms of carbon have been known since antiquity, yet the knowledge of the carbon element in chemistry and its technical applications on a larger scale are a relatively recent development. The industrial revolution in Europe two centuries ago led the way to the numerous applications of these graphitic forms that are still used today. Graphite and Precursors features short tutorial articles on different topics related to the science and technology of carbons intended for engineers, students of Materials Science and scientists who are seeking a fundamental understanding without "reinventing the wheel." This first volume of the World of Carbon book series focuses on graphite and its precursors, including its origin and various implications. The basic properties of hexagonal graphite are developed, and several theoretical and experimental approaches explain why this crystalline solid is fascinating in solid state physics. Also featured are the numerous applications connected to thermal, mechanical and chemical graphites, as well as their various industrial uses in polycrystalline form. Finally, carbon precursors are introduced.
