This book addresses how to estimate substance use and thereby evaluate policies intended to reduce the harms caused by drugs and other substances. Wastewater analysis (WWA) can provide efficient, affordable, fine-grained and objective data on population substance use trends on a very large scale. The authors discuss the potential implications of WWA as a new method for understanding substance use in a variety of settings and ignite a discourse with policy makers, criminologists, epidemiologists and other disciplines about the need for collaboration with WWA scientists. The book also features an explanation of the costs and harms of substance use with academic literature from criminological and epidemiological sources and reports from lead agencies. Additional features include: Details on the origin of wastewater analysis in environmental science Description of analytical chemistry methods for tracing a wide variety of substances, including illicit drugs, alcohol, tobacco and other chemicals Exploration of the major empirical problems in estimating population consumption of alcohol, tobacco and drugs at the international and national level Examination of the principles of human research ethics and their application to wastewater analysis Wastewater Analysis for Substance Abuse Monitoring and Policy Development is a valuable tool for analytical chemists, wastewater scientists and criminologists, as well as researchers and policy makers across disciplines who work in drug sectors.
Xenobiotics are chemical compounds foreign to a given biological system. In animals and humans, xenobiotics include drugs, drug metabolites, and environmental pollutants. In the environment, xenobiotics include synthetic pesticides, herbicides, and industrial pollutants. Many techniques are used in xenobiotics residue analysis; the method selected depends on the complexity of the sample, the nature of the matrix/analytes, and the analytical techniques available. This reference will help the analyst develop effective and validated analytical strategies for the analysis of hundreds of different xenobiotics on hundreds of different sample types, quickly, accurately and at acceptable cost.
Boron has all the best tunes. That may well be the first impression of the Group 13 elements. The chemical literature fosters the impression not only in the primary journals, but also in asteady outflowofbooks focussing more or less closely on boron and its compounds. The same preoccupation with boron is apparent in the coverage received by the Group 13 elements in the comprehensive and regularly updated volume of the Gmelin Handbook. Yet such an imbalance cannot be explained by any inherent lack ofvariety, interest or consequence in the 'heavier elements. Aluminium is the most abundant metal in the earth's crust; in the industrialised world the metal is second only to iron in its usage, and its compounds can justifiably be said to touch our lives daily - to the potential detriment of those and other lives, some would argue. From being chemical curios, gallium and indium have now gained considerably prominence as sources of compound semiconductors like gallium arsenide and indium antimonide. Nor is there any want ofincident in the chemistriesofthe heavier Group 13 elements. In their redox, coordination and structural properties, there is to be found music indeed, notable not always for its harmony but invariably for its richness and variety. Thisbook seeks to redress the balance with a definitive, wide-rangingand up-to-date review of the chemistry of the Group 13 metals aluminium, gallium, indium and thallium.

The final section explores the filtration processes using membranes and the kinetics of separations based on affinity membranes.
Nitroalkenes have often been referred to as "synthetic chameleons" owing to their reactivity, synthetic utility and biological significance. In the last two decades, the reactivity of nitroalkenes as substrates in diverse catalytic asymmetric transformations has been of tremendous interest on account of the powerful abilities of the nitro group to coordinate and withdraw electrons, as well as its amenability to undergo a wide variety of synthetic transformations. Although numerous original articles and reviews have appeared in the literature, a monograph providing a comprehensive coverage of this topic was conspicuous by its absence. This book features: A systematic, up-to-date, in-depth and well-organized compilation, spread over 12 chapters, of various catalytic asymmetric reactions of nitroalkenes with diverse substrates reported to date A wide coverage of reactions such as Michael additions, Friedel-Crafts reactions, cycloadditions, asymmetric reductions, multicomponent and cascade reactions, as well as other miscellaneous reactions Various chiral organo, metal and even biocatalysts involved in the stereoselective synthesis of multifunctional adducts via catalytic asymmetric reactions of nitroalkenes Schemes and figures detailing all the reagents, reaction conditions and product profiles Mechanistic details, including transition state models, which will be useful for effective catalytic design This book will be an invaluable resource for those who are working in the area of asymmetric catalysis and synthetic methodologies.
This monograph consists of manuscripts submitted by invited speakers who participated in the symposium "Industrial Environmental Chemistry: Waste Minimization in Industrial Processes and Remediation of Hazardous Waste," held March 24-26, 1992, at Texas A&M University. This meeting was the tenth annual international symposium sponsored by the Texas A&M Industry-University Cooperative Chemistry Program (IUCCP). The program was developed by an academic-industrial steering committee consisting of the co-chairmen, Professors Donald T. Sawyer and Arthur E. Martell of the Texas A&M University Chemistry Department, and members appointed by the sponsoring companies: Bernie A. Allen, Jr., Dow Chemical USA; Kirk W. Brown, Texas A&M University; Abraham Clearfield, Texas A&M University; Greg Leyes, Monsanto Company; Jay Warner, Hoechst-Celanese Corporation; Paul M. Zakriski, BF Goodrich Company; and Emile A. Schweikert, Texas A&M University (IUCCP Coordinator). The subject of this conference reflects the interest that has developed in academic institutions and industry for technological solutions to environmental contamination by industrial wastes. Progress is most likely with strategies that minimize waste production from industrial processes. Clearly the key to the protection and preservation of the environment will be through R&D that optimizes chemical processes to minimize or eliminate waste streams. Eleven of the papers are directed to waste minimization. An additional ten papers discuss chemical and biological remediation strategies for hazardous wastes that contaminate soils, sludges, and water.

This book is a comprehensive review of the chemistry of what are the simplest and most fundamental species present in aqueous solution for a chemical element - an ‘aqua’ ion. Understanding the chemistry of the aqua ion i.e. the species [M(OH2)n]m+ is fundamental to an appreciation of not only a given elements aqueous solution chemistry, but also to the general chemical properties of that element. The Chemistry of Aqua Ions has been written at a time when environmental issues and the move towards ‘clean technology’ is driving synthetic chemists away from organic based solvent systems and towards water as the preferred medium of the future. The paints industry has already moved to aqueous based products. Metal aqua complexes are widely used in the areas of catalysis, dyes and pigments and in hydrometallurgy where a complete understanding of the metal ions in aqueous media is highly desirable. This is the first book to treat the chemistry of the aqua ions as a self-contained topic. It includes basic concepts relating to the structure of water and periodic trends concerning the state of hydration of metal ions in solution. It examines the significant role that spectroscopic techniques, e.g. NMR, Raman spectroscopy, EXAFS and diffraction techniques have played in establishing the structures of aqua metallic species. Element by element through the periodic table, the author reviews the preparative and separative techniques for aquated ions and their derivatives, physical techniques and their structure and reactivity with a strong emphasis on reaction mechanisms. The Chemistry of Aqua Ions -invaluable reading for all research students in the physical and natural sciences, chemistry, biochemistry, environmental, colloid and soil science, and practicing professional chemists and environmentalists in research and industry.

In its broadest sense, and according to the traditional conception, wood chemistry is a comprehensive discipline, ranging from fundamental studies to practical applications. The manifold constituents, located in different morphological regions in the wood, results in an extreme complexity of wood chemistry. Ever more sophisticated endeavors needing fundamental studies and advanced analytical methods are necessary in order to delve deeper into various problems in pulping and papermaking. Gradually, new, improved ana lytical methods, originally developed for research purposes, are currently replacing many of the old "routine" methods in practical applications. Because of the expanse of the subject, an attempt to write a book of this size about analytical methods seems, perhaps, too ambitious. Of course, a whole book series of several volumes would be necessary to cover this topic completely. However, there is undoubtedly a need for a more condensed presentation which does not go into experimental details, but is limited to the basic principles of the analytical methods and illustrates their applica tions. The emphasis is on more advanced and potential methods, and partic ularly on those based on different types of spectroscopy and chromatography."
