Since the Second World War, Europe has undergone a continual invasion: wave after wave of American popular culture. The diffusion of American culture in Europe is both a European story about America and an American story about Europe. This work examines this cross-cultural phenomenon from the European viewpoint. Nearly two dozen European experts in their respective fields offer an invigorating, engaging, and open-minded examination of America as perceived with the acute insight of the interested European outsider—a fruitful tradition that stretches back to Lafayette, de Tocqueville, and Goethe, to name three. Of interest to scholars, students, and general readers alike.The book's focus is both sensuous and intellectual: how America is seen (The Image); heard (Popular Music); perused (The Written Word); digested (Food); learned from its common ways (Social Customs); perceived by minorities (Ethnic Cultures); and taken as an instrument of change (Americanization). It is the first book of its kind published in the United States. It is rich with selected, up-to-date critical bibliographies in areas for which very little information is otherwise available. In sum: a cogent, cross-cultural analysis of how U.S. popular culture exposes both European dreams of well-being and nightmares of discontent. These are insights which deserve to be savored.

This book covers all aspects of bioavailability, as related to environmental contaminants. After a discussion of the definition of bioavailability and its context, focus is placed on the role of risk assessment and bioavailability. Methods of analysis are then discussed including a range of atomic spectroscopic and electrochemical techniques for metal analysis and chromatographic approaches for persistent organic pollutants (POPs). The occurrence, properties and eco-toxicity of POPs and metals in the soil/sediment environment are discussed. Particular emphasis is placed on the uptake of POPs and metals by plants (phytoextraction). Examples of POPs and metals in the environment are reviewed.Methods to assess the bioavailability of POPs and metals in the environment are discussed. The particular approaches considered are: non-exhaustive extraction techniquessingle extraction techniquessequential extraction techniquesuse of cyclodextrin and surfactantsin-vitro gastrointestinal methods including physiological-based extraction testthe use of bioasssays including earthworms.Finally, selected case studies highlight the importance of determining the bioavailability of POPs and metals.

Provides the basic skills and information required to prepare an environmental sample for analysis. Divided into two sections, i.e. Inorganic Analysis and Organic Analysis, this book covers selected techniques, principally atomic spectroscopy and chromatography. Using flow diagrams to augment the experimental information, it highlights the most appropriate methods and the likely results. Detailed experimental information provided in an easy-to-follow style with illustrationsDescribes the specific sample preparation approaches necessary to analyse a particular sample typeDiscussion of selected literature sources highlights the most appropriate methods and the likely results obtained

Extraction Methods for Environmental Analysis is the first book to bring together all the extraction techniques used for analysis of liquid and solid environmental samples, including solid phase extraction and micro-extraction, supercritical fluid extraction, microwave-assisted extraction and accelerated solvent extraction. The book is divided into two sections - solid sample preparation and liquid sample preparation - to facilitate access, and each section starts with a summary of methods available. The techniques are compared and contrasted by means of 70 bar charts, all in two colours, and 32 tables. Relative merits of the techniques are discussed to enable the user to select the most appropriate technique for their sample and method of analysis. Extraction Methods for Environmental Analysis is essential reading for anyone involved in environmental analysis.

the continued search for rapid, efficient and cost-effective means of analytical measurement has introduced supercritical fluids into the field of analytical chemistry. Two areas are common: supercritical fluid chromatography and supercritical fluid extraction. Both seek to exploit the unique properties of a gas at temperatures and pressures above the critical point. The most common supercritical fluid is carbon dioxide employed because of its low critical temperature (310C), inertness, purity, non-toxicity and cheapness. Alternative supercritical fluids are also used and often in conjunction with modifiers. The combined gas-like mass transfer and liquid-like solvating characteristics have been used for improved chromatographic separation and faster sample preparation. Supercritical fluid chromatography (SFC) is complementary to gas chromatography (GC) and high performance liquid chromatography (HPLC) providing higher efficiency than HPLC, together, with the ability to analyse thermally labile and high molecular weight analytes. Both packed and open tubular columns can be employed, providing the capability to analyse a wide range of sample types.In addition, flame ionization detection can be used thus providing "universal" detection. The separation of complex mixtures by chromatography provides an effective means of identifying individual components. However, as with most techniques, it is the sample preparation which is both time and labour intensive. Traditionally, Soxhlet extraction has been employed but this has several disadvantages when extracting compounds of low and medium polarity using liquid solvents. Extractions are time consuming,. relatively unselective and use large amounts of hazardous solvents, so that further cleanup is usually necessary. Furthermore, after extraction and cleanup steps, the solution must usually be concentrated by evaporation prior to introduction into a chromatograph. Supercritical fluid extraction offers an elegant alternative to the currently applied extraction procedures. The ability of supercritical fluids to deposit extractants by simple depressurisation and/or cryogenic focusing means that solvent concentration can be done quickly and without heat or vacuum. These latter point are particularly important when one is seeking preservation of sensitive analytes.This text therefore seems appropriate at this stage to review the current situation regarding supercritical fluids in analytical chemistry and, to consider the future possibilities to which they may be applied.

This book covers all aspects of environmental trace analysis from sampling through to preparation of the sample to the analytical techniques used to quantify the level of trace metals or organic compounds. The book is divided into two areas: sample preparation for inorganic analysis and sample preparation for organic analysis. This allows the reader to focus on key aspects related to the preparation of samples for their subsequent analysis. Selected case studies provide the reader with the opportunity to consider how the sample preparation approach can be optimized for their own area of expertise.
