Ende April und Anfang Mai 2008 kam es in einigen Regionen in Südwestdeutschland zu Bienenvergiftungen, bei denen nach letzten Erhebungen etwa 11.500 Völker von 700 Imkern teilweise erheblich geschädigt wurden. Sofort nach Bekanntwerden der Vorfälle begann eine intensive Suche nach den Ursachen. Dabei arbeiteten das Ministerium für Ernährung und Ländlichen Raum in Baden-Württemberg (MLR) und die Behörden vor Ort mit der Imkerschaft, der Bienenuntersuchungsstelle im Julius Kühn-Institut (JKI), dem Bundesamt für Verbraucherschutz und Lebensmittelsicherheit (BVL) und der Pflanzenschutzmittel-Industrie zusammen. Schnell richtete sich der Verdacht auf Maissaatgut, das mit dem insektiziden Wirkstoff Clothianidin behandelt war, ein Verdacht, der durch die chemischen Analysen des Julius Kühn-Instituts bestätigt wurde.

Pell's equation is a very simple, yet fundamental Diophantine equation which is believed to have been known to mathematicians for over 2000 years. Because of its popularity, the Pell equation is often discussed in textbooks and recreational books concerning elementary number theory, but usually not in much depth. This book provides a modern and deeper approach to the problem of solving the Pell equation. The main component of this will be computational techniques, but in the process of deriving these it will be necessary to develop the corresponding theory. One objective of this book is to provide a less intimidating introduction for senior undergraduates and others with the same level of preparedness to the delights of algebraic number theory through the medium of a mathematical object that has fascinated people since the time of Archimedes. To achieve this, this work is made accessible to anyone with some knowledge of elementary number theory and abstract algebra. Many references and notes are provided for those who wish to follow up on various topics, and the authors also describe some rather surprising applications to cryptography. The intended audience is number theorists, both professional and amateur, and students, but we wish to emphasize that this is not intended to be a textbook; its focus is much too narrow for that. It could, however be used as supplementary reading for students enrolled in a second course in number theory.

Decision Support Systems for Risk-Based Management of Contaminated Sites addresses decision making in environmental risk management for contaminated sites, focusing on the potential role of decision support systems in informing the management of chemical pollutants and their effects. Considering the environmental relevance and the financial impacts of contaminated sites all over the post-industrialized countries and the complexity of decision making in environmental risk management, decision support systems can be used by decision makers in order to have a more structured analysis of a problem at hand and define possible options of intervention to solve the problem. Accordingly, the book provides an analysis of the main steps and tools for the development of decision support systems, namely: environmental risk assessment, decision analysis, spatial analysis and geographic information system, indicators and endpoints. Sections are dedicated to the review of decision support systems for contaminated land management and for inland and coastal waters management. Both include discussions of management problem formulation and of the application of specific decision support systems. This book is a valuable support for environmental risk managers and for decision makers involved in a sustainable management of contaminated sites, including contaminated lands, river basins and coastal lagoons. Furthermore, it is a basic tool for the environmental scientists who gather data and perform assessments to support decisions, developers of decision support systems, students of environmental science and members of the public who wish to understand the assessment science that supports remedial decisions.

Pyrolysis of Organic Molecules with Applications to Health and Environmental Issues, the 28th volume in the Techniques and Instrumentation in Analytical Chemistry series, gives a systematic and comprehensive description of pyrolysis of non-polymeric organic molecules. Pyrolysis is involved in many practical applications as well as in many common human activities, but harmful compounds can be generated in the process. The study of pyrolysis and of the formation of undesirable compounds as a result of pyrolytic processes is of considerable interest to chemists, chemical engi

Hurricanes are nature’s most destructive agents. They have recently been linked to changes in climate. A 4-day international summit on hurricanes and climate change took place in 2007 to discuss and debate various scientific issues related to this important topic. There were 77 attendees from 18 different countries who participated in the summit. This book is a sample collection of papers from talks that were presented. The chapters are organized around the broad hurricane-climate themes of empirical evidence, statistical methods, and numerical models. A major focus of the conference was the importance of statistical models for understanding how hurricane activity is changing and may change in the future. Emphasis was also placed on evidence of low-frequency swings in hurricane activity using historical and geological records. Results from various high-resolution numerical models, including a 20-km mesh model, were consistent in showing stronger hurricanes in a warmer future. Most numerical models indicate an overall decrease in the number of storms attributable to greater atmospheric stability and to a decrease in vertical mass flux. This book is unique in its scope drawing from an international community of scholars in the field of hurricane climate science. The science addresses a variety of perspectives ranging from the microphysics of lightning to geological evidence of prehistoric storminess.

Meiobenthology is the science of the tiny animals that live in huge numbers in all aquatic sediments. This fully revised and enlarged second edition emphasizes new discoveries and developments in this field. Major progress has been made in three general areas: Systematics, diversity and distribution Ecology, food webs, and energy flow Environmental aspects, including studies of anthropogenic impacts The meiobenthos of polar and tropical regions, deep-sea bottoms and hydrothermal vents are now studied in more detail. The high number of species found to survive under such extreme conditions puts them at the forefront of biodiversity studies. Molecular screening methods enable large numbers to be analyzed upon applying reasonable effort. The aim of this book is to synthesize these modern scientific achievements such that meiobenthology can play a key role in aquatic research and in assessing the health of our environment. From the reviews of the first edition: "Giere's scholarly but readable monograph on the meiobenthos will be welcomed by all aquatic benthic ecologists." Nature "Every librarian and every practicing meiobenthologist should have a copy of this book." Journal of Experimental Marine Biology and Ecology.

How does pollution impact our daily quality of life? What are the effects of pollution on children's development? Why do industry and environmental experts disagree about what levels of pollutants are safe? In this clearly written book, Moore traces the debates around five key pollutants---lead, mercury, noise, pesticides, and dioxins and PCBs---and provides an overview of the history of each pollutant, basic research findings, and the scientific and regulatory controversies surrounding it. Moore focuses, in particular, on the impact of these pollutants on children's psychological development-
