Analytical Methods for Pesticides and Plant Growth Regulators, Volume XV: Principles, Statistics, and Applications covers general principles of pesticide analysis and application of the techniques. The book discusses methods dealing with the analysis of pesticide formulations and residues in biological systems, food, and the environment; government regulations for the safe use of pesticides; and the rationale for the need for pesticide analyses. The text also describes the statistics of sampling and analyses, including the application of computers; clean-up techniques; and the international acceptance and interlaboratory comparisons of pesticide residue data. A discussion, review, and description of analytical methods to meet the unique requirements imposed by analyses of active ingredients in formulations (finished products), pesticide residues in foods and the environment, and pesticide metabolites in plants and animal tissues (metabolism studies) are also considered. People involved in pesticide analysis will find the book invaluable.

This updated and expanded Second Edition of Dr. Erickson's Analytical Chemistry of PCBs appears a decade after the first and is completely revised and updated. The changes from the First Edition reflect the significant growth in the area and a growing appreciation of the importance of PCB analysis to our culture. This book is a comprehensive review of the analytical chemistry of PCBs. It is part history, part annotated bibliography, part comparison, and part guidance. Featuring a new chapter on analyst/customer interactions and several new appendices, the Second Edition is an invaluable resource for both chemists with no experience in PCB analysis and seasoned PCB researchers. All topics have been more thoroughly treated and updated in this new edition to reflect advances made in the last decade, especially:

This book is intended to familiarize readers with the theoretical basis and practical applications of the editing process. This involves the examination of the rhetorical canons-invention, arrangement, style, delivery; and the corresponding rhetorical objectives of editing - accuracy, clarity, propriety, and artistry. We envision a diverse audience for this book. For aspiring editors, we offer an introduction to rhetorical principles as a vehicle for developing a repertoire of theoretically sound and effective strategies. For professionals-directors of communications, public relations specialists, experienced writers and editors of professional and technical publications - this book will serve as a reference and guide reinforcing their intuitive understanding and appreciation of the art of editing.

For more than 30 years, soil testing has been widely used as a basis for determining lime and fertilizer needs. Today, a number of procedures are used for determining everything from soil pH and lime requirement, to the level of extractable nutrient elements. And as the number of cropped fields being tested increases, more and more farmers and growers will come to rely on soil test results. But if soil testing is to be an effective means of evaluating the fertility status of soils, standardization of methodology is essential. No single test is appropriate for all soils. Soil Analysis Handbook of Reference Methods is a standard laboratory technique manual for the most commonly used soil analysis procedures. First published in 1974, this Handbook has changed over the years to reflect evolving needs. New test methods and modifications have been added, as well as new sections on nitrate, heavy metals, and quality assurance plans for agricultural testing laboratories. Compiled by the Soil and Plant Analysis Council, this latest edition of Soil Analysis Handbook of Reference Methods also addresses the major methods for managing plant nutrition currently in use in the United States and other parts of the world. For soil scientists, farmers, growers, or anyone with an interest in the environment, this reference will prove an invaluable guide to standard methods for soil testing well into the future. Features

Modern Methods in the Analysis and Structural Elucidation of Mycotoxins presents available methods of analysis and structural elucidation of mycotoxins by recognized experts in the various disciplines. The approach in each chapter of the book is to present each method initially in theoretical terms and then to review the method as it specifically applies to the analysis and/or structural elucidation of mycotoxins. Comprised of 15 chapters, the book's opening chapters deal with screening, sampling, and survey methods for mycotoxins and toxigenic fungi. This is followed by chapters dealing mostly with methods for structural elucidation, such as NMR and X-ray crystallography and IR and UV spectroscopy, as well as biosynthetic techniques. Significant chapters consider the analytical methods for mycotoxin analyses, including enzyme-linked immunosorbent assay system and tandem mass spectrometry. The concluding chapter examines the mycotoxin analytical problem in taxonomic or ecological terms. This book is of value to food and feed researchers, scientists, and manufacturers who are interested in product contamination control.

The field of antioxidant research has grown rapidly over the last 30 years and shows no sign of slowing down. In order to understand how antioxidants work, it is essential to understand how their activity is measured. However, antioxidant activity measurements are controversial and their value has been challenged. This book addresses a number of the controversies on antioxidant testing methods. Specifically, the book highlights the importance of context, helping the reader to decide what methods are most appropriate for different situations, how the results can be interpreted and what information may be inferred from the data. There are a multiplicity of methods for measuring activity, with no standardized method approved for in vitro or in vivo testing. In order to select an appropriate method, a thorough knowledge of the processes associated with reduction-oxidation is essential, leading to an improved understanding and use of activity measurements and the associated data. The book presents background information, in a unique style, which is designed to assist readers to grasp the fundamentals of redox processes, as well as thermodynamics and kinetics, which are essential to later chapters. Recovery and extraction of antioxidants from diverse matrices are presented in a clear and logical fashion along with methods used to determine antioxidant activity from a mechanistic perspective. Other chapters present current methodologies used for activity testing in different sample types ranging from foods and plants, to body fluids and even to packaging, but always with a strong emphasis on the nature of the sample and the underlying chemistry of the method. A number of emerging techniques for assessing antioxidant behaviour, namely, electrochemical methods, chip technology exploiting microfluidic devices, metabolomics plus studies of gene and protein expression, are examined. Ultimately, these techniques will be involved in generation of "big data" for which an understanding of chemometrics will be essential in drawing valid conclusions. The book is written to appeal to a wide audience, but will be particularly helpful for any researchers who are attempting to make sense of the vast literature and often conflicting messages on antioxidant activity.
