How could plastic-eating bacteria help reduce waste? Can a river be given human rights? Could we generate all the power we need from the sun and the wind? How do woolly sweaters help penguins in peril? Would building a giant sunshade in space stop the world from overheating? Find the answers to these questions and more in this exciting book full of big, small and unexpected ways to save the planet.

Persistent organic pollutants (POPs) and toxic elements, such as dioxins, flame retardants, lead and mercury, are substances of major concern for the food industry, the regulator and the public. They persist in the environment, accumulate in food chains and may adversely affect human health if ingested over certain levels or with prolonged exposure. Persistent organic pollutants and toxic metals in foods explores the scientific and regulatory challenges of ensuring that our food is safe to eat.
Part one provides an overview of regulatory efforts to screen, monitor and control persistent organic pollutants and heavy metals in foods and includes case studies detailing regulatory responses to food contamination incidents. Part two moves on to highlight particular POPs, toxic metals and metalloids in foods, including dioxins and polychlorinated biphenyls (PCBs), mercury, polycyclic aromatic hydrocarbons (PAHs) and phthalates.
Persistent organic pollutants and toxic metals in foods is a standard reference for those in the food industry responsible for food safety, laboratories testing for food chemical safety, regulatory authorities responsible for ensuring the safety of food, and researchers in industry and academia interested in the science supporting food chemical safety.
Includes case studies which detail regulatory responses to food contamination incidentsConsiders the uptake and transfer of persistent organic pollutants in the food chain and the risk assessment of contaminates in foodDetails perticular persistent organic pollutants, toxic metals and metalloids in foods including polychlorinated biphenyls (PCBs), per- and polyfluoroalkyl substances (PFASs), mercury and arsenic among others

Service Life Prediction of Polymeric Materials: Global Perspectives combines developed content derived from topics discussed in the Fourth International Symposium on Service Life Prediction (Key Largo, Florida, December 2006). This critical examination of the existing and alternative methodologies used to assess the service life of polymeric materials presents readers with the advances in accelerated and field exposure testing protocols. Written by established experts in the service life community, this volume introduces advanced methods, including high throughput and combinatorial analyses, models data collection and storage formats.

Researchers and engineers involved with materials and polymer science, coatings technologists and automotive materials will find Service Life Prediction of Polymeric Materials: Global Perspectives a useful tool.

Progressive Besteuerung kann nicht nur als ein Instrument zur Optimie- rung einer sozialen Wohlfahrtsfunktion gesehen werden, sondern auch als Ergebnis einer Minimierung bestimmter negativer Querbeziehungen von Menschen zueinander. Diese Deutung einer progressiven Einkommen- steuer bietet eine alternative Erklarung des Umverteilungsstaates. Hierbei ist das Menschenbild des Einzelnen dtisterer als das der neo- klassischen Tradition. Wird doch implizit angenommen, daB es ftir den Einzelnen nicht erwtinscht sei, wenn andere in einer Position sind, die er lieber hatte. Aber, woher kommt eigentlich dieser bias der Neoklas- sik, daB sie einseitig egozentrische Menschen in ihrem Menschenbild der Praferenzrelationen akzeptiert, daB sie auch noch bereit ist, alt- ruistische Menschen anzunehmen, aber eine psychologische Erscheinung wie den Neid verdrangen mochte? Moglicherweise liegt der Grund darin, daB man ein gewisses AusmaB an Nejd als leistungserhohende Triebkraft eines Menschen ansieht, also sogar positiv zu bewerten bereit ist. Dies andert aber nichts daran, daB zunehmender Neid die noch naher zu erklarende "Supernutzenfunktion" der einzelnen Individuen in einer Gesellschaft reduziert, so daB auch eine Gesellschaft mit hohem Sozial- produkt, aber sehr intensiven Neidbeziehungen insgesamt wohlfahrtsmaBig ungtinstiger dastehen kann als eine mit niedrigerem Sozialprodukt, aber Reduzierung der Neidbeziehungen.

Morocco is a country that has been much invaded, much traveled though, and much written about in many languages. Positioned at the entrance to Africa-or the entrance to Europe-it has seen deep cultural cross-fertilization and the emergence of a very distinct culture at the threshold of two worlds. Its history is exciting and colorful; its ancient cities extraordinary in their preservation; and its people magnetic. It has drawn travelers and writers for many centuries, and continues to do so today, with the result that there exists a rich seam of description and sometimes quizzical (but generally very fond) appreciation, which Martin Rose, a long-time resident of the country, has been able to mine for this fascinating anthology.
