A thorough and timely update, this new edition presents principles, techniques, and applications in this sub-discipline of analytical chemistry for quantifying traces of potentially toxic organic and inorganic chemical substances found in air, soil, fish, and water, as well as serum, plasma, urine, and other body fluids. The author addresses regulatory aspects, calibration, verification, and the statistical treatment of analytical data including instrument detection limits; quality assurance/quality control; sampling and sample preparation; and techniques that are used to quantify trace concentrations of organic and inorganic chemical substances. Key Features: Fundamental principles are introduced for the more significant experimental approaches to sample preparation Principles of instrumental analysis (determinative techniques) for trace organics and trace inorganics analysis An introduction to the statistical treatment of trace analytical data How to calculate instrument detection limits based on weighted least squares confidence band calibration statistics Includes an updated series of student-tested experiments
Laboratory Experiments in Trace Environmental Quantitative Analysis is a collection of student-tested experiments that introduce important principles that underlie various laboratory techniques in the field of trace environmental organics and inorganics quantitative analysis. It crosses the more traditional academic disciplines of environmental science and analytical chemistry. The text is organized to begin with minimally rigorous session/experiments and increase in rigor as each session/experiment unfolds. Each experiment features learning objectives, expected student outcomes, and suggestions for further study. Additional features include: Students are introduced to the principles and laboratory practice of instrumental analysis (determinative techniques) that are clearly presented. Students are carefully taken through various ways to prepare samples for trace quantitative analysis (sample prep techniques). Safety warnings are listed within each experiment. Students are introduced to all three types of instrument calibration: external, internal and standard addition. Instructors who are responsible for laboratory courses in analytical chemistry with potential application to environmental sample matrices will find this textbook of value. Graduate programs in environmental science and engineering will also greatly benefit from the content.
This study offers insight into the principles of trace environmental quantitative analysis (TEQA), focusing on data reduction and interpretation, sample preparation and instrumental analysis from a wide range of matrices, including sludge, sediment, oil and air, as well as ground, waste and surface water. It draws on the author's own research with metal chelate solid-phase extraction.
This book provides a serious introduction to the subject of mass spectrometry, providing the reader with the tools and information to be well prepared to perform such demanding work in a real-life laboratory. This essential tool bridges several subjects and many disciplines including pharmaceutical, environmental and biomedical analysis that are utilizing mass spectrometry: Covers all aspects of the use of mass spectrometry for quantitation purposes Written in textbook style to facilitate understanding of this topic Presents fundamentals and real-world examples in a ‘learning-though-doing’ style
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.
Trace Environmental Quantitative Analysis: Principles, Techniques, and Applications, Second Edition offers clear and relevant explanations of the principles and practice of selected analytical instrumentation involved in trace environmental quantitative analysis (TEQA). The author updates each chapter to reflect the latest improvements in TEQA that have resulted in greater levels of sensitivity. The book begins with an overview of regulatory and EPA methods, followed by quantitative data reduction and interpretation of analytical results, sample preparation, and analytical instrumentation. Among the more than two-dozen new topics are the underlying principles of GC-MS, GC-MS-MS, LC-MS, and ICP-MS, column chromatographic cleanup, gel permeation chromatography, applications to biological sample matrices, and matrix solid-phase dispersion. The chapter on sample preparation now includes more alternatives to liquid-liquid extraction, highlighting Solid Phase Microextraction (SPME), and Stir Bar Sorptive Extraction (SBSE). The final chapter contains laboratory-tested experiments to practice the techniques appearing in the text. Appendices include a convenient glossary, applications to drinking water, computer programs for TEQA, instrument designs, and useful Internet links for practicing environmental analytical chemists. Featuring personal insight into the theory and practice of trace analysis from a bench analytical chemist, the second edition of Trace Environmental Quantitative Analysis takes readers from the fundamental principles to state-of-the-art methods of TEQA currently used in leading laboratories.
Environmental Analysis contains the papers presented at the Third Annual Meeting of the Federation of Analytical Chemistry and Spectroscopy Societies in Philadelphia, Pennsylvania, November 15-18, 1976. A large number of papers were devoted to solving environmental problems. Some consisted of reviews of the state of the art with respect to specific techniques, while others represented the results of applying such techniques to particular situations. The book contains 23 papers that cover topics such as the contribution of atmospheric precipitation to the material balance of Lakes Huron and Superior; an improved method for the determination of adenosine triphosphate; and the use of a flame resonance spectrometer to analyze a range of environmental samples. Other studies include the recovery and identification of phenolic compounds from natural waters in and around petroleum industries; methods for determining of lead pollutants in air; a method for colorimetric analysis of ammonia in water; and the application of micro-Raman spectroscopy to the chemical characterization of single particles in air particulate dusts.

Applications of X-ray spectroscopy to air, water, and soil pollution studies are covered in detail in this essential publication. Air pollution can hardly be studied by any other method to such an extent. Much of our present knowledge in this field was obtained by laboratories using many of the same methods described in this work. A number of examples illustrate the contribution of X-ray emission spectroscopy and its capabilities in the area of water pollution. Examples of soil pollution studies by the use of biological monitors is also presented. A comprehensive reference list with the help of author and subject indices provides direction for further investigation.
