The emphasis in degradable polymers has changed since the first edition of this book. Biomedical and agricultural applications remain important topics of scientific and commercial interest in the second edition. However, an increased emphasis on composting as a means of recovering value from wastes has led to a new impetus to understand how plastics degrade in the environment and the implication of this for international standards. Polymers based on renewable resources are also a major topic in this edition but the debate continues about their long-term sustainability and ecological...

September 11, 2001 in the U.S., March 11, 2004 in Madrid - just two examples of a series of major terror attacks against NATO member states on both sides of the Atlantic. We now know that international terrorism is capable of transboundary planning and military style execution of attacks, resulting in several thousand dead and wounded. In the future even larger terror attacks can no longer be ruled out, including the deployment of weapons of mass destruction. This new form of catastrophic terrorism poses a major challenge to the first responder community in their search and rescue...

Safety of Meat and Processed Meat provides the reader with the recent developments in the safety of meat and processed meat, from the abattoir along the processing chain to the final product. To achieve this goal, the editor uses five approaches. The first part deals with the main biological contaminants like pathogen microorganisms, specially E. coli and L. monocytogenes, toxins and biogenic amines that can be present either in meat or its derived products. The second part focuses on main technologies for meat decontamination as well as developments like active packaging or bioprotective...

Reports that heat processing of foods induces the formation of acrylamide heightened interest in the chemistry, biochemistry, and safety of this compound. Acrylamide-induced neurotoxicity, reproductive toxicity, genotoxicity, and carcinogenicity are potential human health risks based on animal studies. Because exposure of humans to acrylamide can come from both external sources and the diet, there exists a need to develop a better understanding of its formation and distribution in food and its role in human health. To contribute to this effort, experts from eight countries have presented...
