Since the mid 1990s, legal action to eliminate persistent organic pollutants (POPs) has started resulting in a global Convention on POPs, the Stockholm Convention, and a regional Protocol under the Convention on Long-Range Transboundary Air Pollution (UN-ECE LRTAP Convention). POPs are characterized by long half-lives, persistence in the environment, they undergo long-range transport, accumulate in the environment and in biota, and they are toxic. The combination of these characteristics makes them a threat at the global level. This book makes the reader familiar with the goals of these two conventions, lays out characteristics of these compounds, presents results from case studies and addresses inventories, levels in humans and the environment as well as technologies to destroy them.

This review discusses the legal requirements and property specifications for blowing agents in different applications. Each type of blowing agent is described. Key environmental and physical properties are listed, together with advantages and limitations. Foams are described by types and by applications. An additional indexed section containing several hundred abstracts from the Polymer Library gives useful references for further reading.
Originally published in 1990 this book provides an authoritative and detailed account of the initiatives of US state governments with science and technology programs designed to foster economic growth. Two key questions are posed: Do state governments have policy instruments that are sufficiently powerful to affect thelevels and growth rates of their regional economies? and Are national and global economic forces so powerful that they render state action ineffective? Several subsidiary themes are discusses in this context, namely: the most commonly used policy instruments, the impacts on federalism and on governance and how well the universities and other educational institutions serve the economic activities imposed on them.
The identification and control of food contaminants rely on careful investigation and implementation of appropriate management strategies. Using a wide range of real-life examples, Case studies in food safety and authenticity provides a vital insight into the practical application of strategies for control and prevention. Part one provides examples of recent outbreak investigations from a wide range of experts around the world, including lessons learnt, before part two goes on to explore examples of how the source was traced and the implications for the food chain. Methods of crisis management are the focus of part three, whilst part four provides studies of farm-level interventions and the tracking of contaminants before they enter the food chain. Part five is focussed on safe food production, and considers the challenges of regulatory testing and certification, hygiene control and predictive microbiology. The book concludes in part six with an examination of issues related to food adulteration and authenticity. With its distinguished editor and international team of expert contributors, Case studies in food safety and authenticity is a key reference work for those involved in food production, including quality control, laboratory and risk managers, food engineers, and anyone involved in researching and teaching food safety.
