Each chapter contains tables summarizing the key steps of the procedures developed for the trace element determination and the detection characteristics reported.

and used in munitions. Rather the requirements for the agent's military effects took precedence. In addition, the interaction among the political, technical, and legal challenges connected with the known or possible risks posed by CW agents is complex and sometimes not well understood. This is usually because technical considerations, when acted on, are almost invariably informed by political ones, such as various legal requirements. The book contains nine chapters covering different aspects of the research on environmental consequences of war and its aftermath and covers in one additional chapter more general issues such as prevention of war and its environmental c- sequences, the legal, political, and technical background to selected environmental and human health effects of CW agents, and the atmospheric transport and depo- tion of persistent organic pollutants under warfare conditions to more specific ones related to two main tragic examples: the war in the Balkans and the Gulf War. Aspects of the war in the Balkans cover contamination by heavy metals in Serbian national parks, the impact of NATO strikes on the Danube river basin, and the problems associated with transuranium elements. The Gulf War in Kuwait covers other problems related to the impact of oil contamination, the impact on grou- water resources, and the soil damage of ground fortifications among other envir- mental and health problems.

The application of nanotechnology in different consumer products has delivered new products with highly desirable properties, but at same time has opened a new window for a wide group of emerging contaminants and a new type of human exposure which needs to be assessed.

Most of the current human toxicological information on nanomaterials comes from nano-sized particles in air, and their effects via inhalation. Other routes of human exposure, such as water and food, and the effects on human health and the environment have been less studied. It is the recent research in these areas that is highlighted here in one of the first books covering the analysis and ecotoxicological evaluation of nanomaterials in food and the environment, with both matrices being of considerable interest. In addition to providing a global summary of recent research, this book shows how widely used chromatographic and spectroscopic methods can be added to the analytical arsenal of microscopic techniques that have commonly been used to characterize nanomaterials.

This second edition of a successful and highly-accessed monograph has been extended by more than 100 pages. It includes an enlarged coverage of applications for materials characterization and analysis. Also a more detailed description of strategies for determining free energies of ion transfer between miscible liquids is provided. This is now possible with a "third-phase strategy" which the authors explain from theoretical and practical points of view. The book is still the only one detailing strategies for solid state electroanalysis. It also features the specific potential of the techniques to use immobilized particles (for studies of solid materials) and of immobilized droplets of immiscible liquids for the purpose of studying the three-phase electrochemistry of these liquids. This also includes studies of ion transfer between aqueous and immiscible non-aqueous liquids. The bibliography of all published papers in this field of research has been expanded from 318 to now 444 references in this second edition. Not only are pertinent references provided at the end of each chapter, but the complete list of the cited literature is also offered as a separate chapter for easy reference.

With the development in the 1960s of ultrahigh vacuum equipment and techniques and electron, X-ray, and ion beam techniques to determine the structure and composition of interfaces, activities in the field of surface science grew nearly exponentially. Today surface science impacts all major fields of study from physical to biological sciences, from physics to chemistry, and all engineering disciplines. The materials and phenomena characterized by surface science range from se- conductors, where the impact of surface science has been critical to progress, to metals and ceramics, where selected contributions have been important, to bio- terials, where contributions are just beginning to impact the field, to textiles, where the impact has been marginal. With such a range of fields and applications, questions about sample selection, preparation, treatment, and handling are difficult to cover completely in one review article or one chapter. Therefore, the editors of this book have assembled a range of experts with experience in the major fields impacted by surface characterization. It is the only book which treats the subject of sample handling, preparation, and treatment for surface characterization. It is full of tricks, cautions, and handy tips to make the laboratory scientist's life easier. With respect to organization of the book, the topics range from discussion of vacuum to discussion of biological, organic, elemental or compound samples, to samples prepared ex situ or in situ to the vacuum, to deposition ofthin films. Generic considerations of sample preparation are also given.

This book covers new materials used as analytical devices for increasing the interactions between the development of new analytical devices and materials science. The authors describe how different types of materials such as polymers, self-assembled layers, phthalocyanines, and nanomaterials can further enhance sensitivity and promote selectivity between analytes for different applications. They explain how continuing research and discussion into materials science for chemical sensing is stimulating the search for different strategies and technologies that extract information for these chemical sensors in order to obtain a chemical fingerprint of samples.

Assuming only background knowledge of algebra and elementary calculus, and access to a modern personal computer, Nonlinear Computer Modeling of Chemical and Biochemical Data presents the fundamental basis and procedures of data modeling by computer using nonlinear regression analysis. Bypassing the need for intermediary analytical stages, this method allows for rapid analysis of highly complex processes, thereby enabling reliable information to be extracted from raw experimental data.
By far the greater part of the book is devoted to selected applications of computer modeling to various experiments used in chemical and biochemical research. The discussions include a short review of principles and models for each technique, examples of computer modeling for real and theoretical data sets, and examples from the literature specific to each instrumental technique.
The book also offers detailed tutorial on how to construct suitable models and a score list of appropriate mathematics software packages.

Determining the composition and properties of complex hydrocarbon mixtures in petroleum, synthetic fuels, and petrochemical products usually requires a battery of analytical techniques that detect and measure specific features of the molecules, such as boiling point, mass, nuclear magnetic resonance frequencies, etc. there have always been a need for new and improved analytical technology to better understand hydrocarbon chemistry and processes. This book provides an overview of recent advances and future challenges in modern analytical techniques that are commonly used in hydrocarbon applications. Experts in each of the areas covered have reviewed the state of the art, thus creating a book that will be useful to readers at all levels in academic, industry, and research institutions.

Medical Applications of Electrochemistry, a volume of the series Modern Aspects of Electrochemistry, illustrates the interdisciplinary nature of modern science by indicating the many current issues in medicine that are susceptible to solution by electrochemical methods. This book also suggests how personalized medicine can develop.

This new book on additives used in plastics for food contact, can be seen as a companion to the 1993 publication Spectra for the Identification of Monomers in Food Packaging [1, 2]. That earlier book presented information on monomeric substances listed in Directive 901128/EEC [3], which restricts the range of monomers and other starting substances that can be used for the production of plastics materials and articles intended for food contact applications. As a logical supplement to the collection of monomers and other starting substances, the preparation of a reference collection and a Handbook of analytical data of additives was undertaken with funding from The European Commission under the Standards Measurements and Testing programme. We then give a collection of spectra for the identification of 100 of the most important additives used in plastics packaging and coatings. Infra-red (FT-IR) and mass spectra (MS) are presented, as in the monomers book, but we have extended the scope to include proton nuclear magnetic resonance eH-NMR) spectra and gas-chromatographic (GC) data. Legal Framework The Commission of the European Communities provides in Synoptic Document N. 7 [4] a provisional list of additives used for the production of food contact plastics. This Synoptic Document anticipates a Directive on additives for food contact plastics. One hundred of the most important additives were selected from this provisional list after extensive consultation with researchers in the field and with representatives from European industry (Food Contact Additives Panel (FCA) sector group of the European Chemical Industry Council (CEFIC).

In response to the demands of contemporary solid material analysis-greater powers of detection, speed, depth, and precision-glow devices are receiving increased attention by specialists. This volume covers fundamental plasma processes, laser-based methods, thin film analysis, and many other processes to provide the researcher with an extensive technical reference of these devices.

This book, Organic Photochromic and Thermochromic Compounds, is the fourth major treatise on photochromism involving organic molecules and derived systems. The first such book was edited by G.H. Brown in the Weissberger series in 1971, the second was edited by H. DA1/4rr and H. Bouas-Laurent in the Elsevier series in 1990. A third book, edited by C.B. McArdle, should be added to the list, which focuses on the very important topic of the behavior of photochromic systems in polymer matrices. The current book is a result of the large increase in the number of publications and patents concerning photochromic compounds and their use in various applications (e.g. ophthalmic lenses, security printing, etc.) during the last 10 years. As a result of this increased interest, two successful International Symposia on Photochromism have been held: the first, ISOP93, in France on Embiez Island near Bandol (September 12-16, 1993) and the second, ISOP96, in the United States in Clearwater, Florida (September 8-12, 1996). The number of countries represented at each of these symposia (17 and 16, respectively) attests to the international scope of the photochromic research community. This global interest is also exemplified by the authors of the chapters within this book. The second volume of this new review is focused on the physico-chemical properties and photochromic behavior of the best-known systems, which have led to new developments in the known photochromic series or the discovery of new families. Chapters are included on the most appropriate physico-chemical methods by which photochromic substances can be studied (spectrokinetic studies on photostationary states, Raman spectroscopy, EPR, chemicalcomputations and molecular modeling, X-ray diffraction analysis). In addition, special topics such as interaction between photochromic compounds and polymer matrices, photodegradation mechanisms, and potential biological applications have been treated. The last chapter, on thermochromic materials, is included to emphasize the chemical similarities between photochromic and thermochromic materials. In general, the literature cited within the chapters covers publications through 1995.

Volumes are organized topically and provide a comprehensive discussion of developments in the respective field over the past 3-5 years. The series also discusses new discoveries and applications. Special volumes are dedicated to selected topics which focus on new biotechnological products and new processes for their synthesis and purification. In general, special volumes are edited by well-known guest editors. The series editor and publisher will however always be pleased to receive suggestions and supplementary information. Manuscripts are accepted in English.

Through this monograph, the pharmaceutical chemist gets familiar with the possibilities electroanalytical methods offer for validated analyses of drug compounds and pharmaceuticals. The presentation focuses on the techniques most frequently used in practical applications, particularly voltammetry and polarography. The authors present the information in such a way that the reader can judge whether the application of such techniques offers advantages for solving a particular analytical problem. Basics of individual electroanalytical techniques are outlined using as simple language as possible, with a minimum of mathematical apparatus. For each electroanalytical technique, the physical and chemical processes as well as the instrumentation are described. The authors also cover procedures for the identification of electroactive groups and the chemical and electrochemical processes involved. Understanding the principles of such processes is essential for finding optimum analytical conditions in the most reliable way. Added to this is the validation of such analytical procedures. A particularly valuable feature of this book are extensive tables listing numerous validated examples of practical applications. Various Indices according to the drug type, the electroactive group and the type of method as well as a subject and author index are also provided for easy reference.

The book covers a critical compilation of analytical methods used for the monitoring of pesticides and their degradation products in water. It contains up-to-date material and is the direct result of the authors' experience in the field of pesticide analysis. The book is structured in six chapters, starting from general aspects of pesticides like usage, physicochemical parameters and occurrence in the environment. A second chapter is devoted to sampling from water matrices, stability methods of pesticides in water and quality assurance issues. The general chromatographic methods for pesticides are reported, including the newly developed electrophoresis methods and GC-MS and LC-MS confirmatory analytical methods. Sample preparation methodologies, including off-line and on-line techniques are described in the next two chapters, with a comprehensive list of examples of pesticides and many metabolites, including the use of different GC-methods and LC-methods. The final chapter is devoted to the development of biological techniques, immunoassays and biosensors, for the trace determination of pesticides in water samples.

The book answers one of the key problems in pesticide analysis: the diversity of chemical functional groups, with varying polarity and physicochemical properties. Pesticides and their metabolites have received particular attention during the last few years in environmental trace-organic analysis. For instance, in the case of groundwater, the use of pesticides has become a cause for concern. Under the right conditions, pesticides, such as fertilizer nitrogen, can move through the soil into groundwater, a phenomenon once thought improbable. The movement of agrochemicals in surface water flow can be, in some instances, a major problem, specially in the case of water soluble pesticides that are generally transported to estuarine and coastal waters. Estuarine waters feature gradients of both pollutant concentrations and physicochemical characteristics such as salinity, turbidity and pH, and all these parameters must be carefully considered when developing methods of analysis for trace organics in estuarine waters.

One of the key parameters in analytical determination is the environmental sampling. Different protocols and devices are needed for sampling sea-water samples - usually using large sample volumes of more than 50 litres either with LLE or SPE, with the problems encountered due to dissolved and particulate matter - which is different from drinking water and well water sampling. The representativeness of the sampling is also of concern.

The sample preparation of organic compounds from water matrices has been recognized to be a bottleneck and it has been traditionally neglected in the literature. We should comment following R.W. Frie's ideas - that the most sophisticated hardware is useless if the chemistry in the protocol does not work. During the last few years new adsorbents have appeared - carbon type, polymeric sorbents with high capacity and immunosorbents - which can more efficiently trap the more polar compounds.

The development of advanced automation methods based, usually on solid phase extraction techniques - PROSPEKT, OSP-2 and ASPEC XL - are examples of commercially available equipment that are of growing importance. These systems are generally coupled to LC and GC techniques.

Sampling and sample handling can not be regarded as separate techniques in the analytical process and both should be integrated into the whole analytical determination. For this reason, validation and confirmation methods, such as mass spectrometry, either GC-MS and/or LC-MS, are needed. These serve to check the quality assurance of the developed method. The discussion between multiscreening versus specific methods of analysis and the influence of the matrix (ground-, surface- and estuarine-water), is also a point of concern due to the diversity of chemical classes within the compounds of study.

Finally the use of rapid methods of analysis, which refer basically to biological techniques, biosensors and immunoassays are also of growing interest for the determination of pesticides in environmental matrices. The rapid development of these techniques, being more sensitive and that can work at different pH and drastic environmental conditions, like very different pH and salinity values, makes that these methods are very useful and complementary to conventional GC and/or LC techniques for the determination of pesticides.

Addressing the origin, current status, and future development of point-of-care diagnostics, and serving to integrate knowledge and tools from Analytical Chemistry, Bioengineering, Biomaterials, and Nanotechnology, this book focusses on addressing the collective and combined needs of industry and academia (including medical schools) to effectively conduct interdisciplinary research. In addition to summarizing and detailing developed diagnostic devices, this book will attempt to point out the possible future trends of development for point-of-care diagnostics using both scientifically based research and practical engineering needs with the aim to help novices comprehensively understand the development of point-of-care diagnostics. This includes demonstrating several common but critical principles and mechanisms used in point-of-care diagnostics that address practical needs (e.g., disease or healthcare monitoring) using two well-developed examples so far: 1) blood glucose meters (via electrochemistry); and, 2) pregnancy tests (via lateral flow assay). Readers of this book will come to fully comprehend how to develop point-of-care diagnostics devices, and will be inspired to contribute to a critical global cause - the development of inexpensive, effective, and portable in vitro diagnostics tools (for any purpose) that can be used either at home or in resource limited areas.
