J. W. Einax, H. W. Zwanziger S. Gei Chemometrics in Environmental Analysis Make the most of your data! This new title will serve both as an introduction and as a practical guide to those techniques of chemometrics which are applicable to environmental analysis. By describing the optimum methods of data analysis it will help all chemists in this field to save time and money. Because the authors demonstrate the most important chemometric methods with the aid of numerous examples, the reader will learn to solve a given problem by use of the appropriate method. Applications range from sampling, through laboratory analysis, to evaluation. Interpretation of the findings is explained clearly. The text covers not only basic methods such as univariate statistics, regression analysis, and statistical test planning, but also multivariate data analysis, for example, cluster analysis, principal components analysis, and factor and discriminant analysis. Case studies show the enormous possibilities, and the limits, of chemometric methods. The book will help all environmental analytical scientists, even those with only a basic knowledge of mathematics, to optimize the evaluation and interpretation of the results of their measurements.

Multivariate, heterogeneous data has been traditionally analyzed using the "one at a time" variable approach, often missing the main objective of discovering the relationships among multiple variables and samples. Enter chemometrics, with its powerful tools for design, analysis, and data interpretation of complex environmental systems. Delineating the rigors of modern environmental analysis and how to effectively solve limitations through multivariate approaches, Environmental Chemometrics: Principles and Modern Applications provides an introduction and practical guide to chemometric methods used in environmental chemical analysis. The text begins with an overview of chemometrics in relation to quantitative environmental analysis and a review of descriptive statistical concepts. Building on this, the author covers environmental sampling considerations, experimental design and optimization techniques, multivariate analysis of environmental and chemical data sets, time series analysis, and quality assurance and method validation. Each chapter contains problem-oriented exercises and research applications from the author’s own work and from other experts in the field. The author’s presentation of the basic principles of these methods together with real applications in the field of environmental chemistry makes the comprehension of complex environmental problems and chemically-related concepts more accessible. He covers all major areas of environmental analysis backed by studies from experts in the field. The book is a valuable tool for understanding the rapidly developing world of chemometric methods in environmental analysis.

Modern Environmental Analysis Techniques for Pollutants presents established environmental analysis methods, rapidly emerging technologies, and potential future research directions. As methods of environmental analysis move toward lower impact, lower cost, miniaturization, automation, and simplicity, new methods emerge and ultimately improve the accuracy of their analytical results. This book gives in-depth, step-by-step descriptions of a variety of techniques, including methods used in sampling, field sample handling, sample preparation, quantification, and statistical evaluation. Modern Environmental Analysis Techniques for Pollutants aims to deliver a comprehensive and easy-to-read text for students and researchers in the environmental analysis arena and to provide essential information to consultants and regulators about analytical and quality control procedures helpful in their evaluation and decision-making procedures. Bridges the gap in current literature on analytical chemistry techniques and their application to environmental analysis Covers the use of nanomaterials in environmental analysis, as well as the monitoring and analysis of nanomaterials in the environment Looks to the past, present and future of environmental analysis, with chapters on historical background, established and emerging techniques and instrumentation, and predictions

Notwithstanding the vast amount of environmental analytical chemical literature available, publications dealing with environmental analytical chemistry in a general, integrated manner are rather scant. In fact, most literature on such a relevant topic appears to touch on individual aspects such as water or air pollution, applicable conventional or special equipment used with given matrices and specific pollutant groups. Most of these books are of interest to experts and only a few, if any, provide less experienced readers with a systematic, comprehensive description of environmental analytical issues. This book, which is intended to fill the gap, approaches the subject by focusing on the sample and its handling. The fourteen chapters that make up the book follow a logical sequence of sample matrices and analyte types. The first six are of paramount importance, as they lay the foundations for a basic, yet comprehensive coverage of the subject in the others. Following the required introduction to environmental chemistry, Chapters 2 to 6 deal sequentially with environmental quality assurance, quality control fundamentals and practical aspects of environmental sampling, the preconcentration of environmental samples and environmental control standards. Chapters 7 to 12 are concerned with the analytical control of inorganic and organic pollutants in air, water and soil. Finally, the last two chapters are devoted to speciation and chemometrics in environmental analysis. Each chapter presents the state-of-the-art of the environmental topic covered, and illustrates it with a wealth of practical examples. Overall, the book contains about one hundred tables, almost two hundred figures and more than 1700 references, all of which make it a pedagogical, current reference work. On the borderline between a textbook and a monograph, it is intended to be useful both as an academic text for the burgeoning number of undergraduate and postgraduate courses on the subject, as a reference book for those starting work in the environmental field and as a source of first-hand information on environmental science and its practical laboratory aspects.

Environmental modelling has enjoyed a long tradition, but there is a defined need to continually address both the power and the limitations of such models, as well as their quantitative assessment. This book showcases modern environmental modelling methods, the basic theory behind them and their incorporation into complex environmental investigations. It highlights advanced computing technologies and how they have led to unprecedented and adaptive modelling, simulation and decision-support tools to study complex environmental systems, and how they can be applied to current environmental concerns. This volume is essential reading for researchers in academia, industry and government-related bodies who have a vested interest in all aspects of environmental modelling. Features include: A range of modern environmental modelling techniques are described by experts from around the world, including the USA, Canada, Australia, Europe and Thailand; many examples from air, water, soil/sediment and biological matrices are covered in detail throughout the book; key chapters are included on modelling uncertainty and sensitivity analysis; and, a selection of figures are provided in full colour to enable greater comprehension of the topics discussed
