Compound-specific Stable Isotope Analysis
Author: Maik A JochmannPublisher: Royal Society of Chemistry
ISBN: 1782626107
Category : Science
Languages : en
Pages : 306
Book Description
The use of Compound-specific Stable Isotope Analysis (CSIA) is increasing in many areas of science and technology for source allocation, authentication, and characterization of transformation reactions. Until now, there have been no textbooks available for students with an analytical chemical background or basic introductory books emphasising the instrumentation and theory. This book is the first to focus solely on stable isotope analysis of individual compounds in sometimes complex mixtures. It acts as both a lecture companion for students and a consultant for advanced scientists in fields including forensic and environmental science. The book starts with a brief history of the field before going on to explain stable isotopes from scratch. The different ways to express isotope abundances are introduced together with isotope effects and isotopic fractionation. A detailed account of the required technical equipment and general procedures for CSIA is provided. This includes sections on derivatization and the use of microextraction techniques in GC-IRMS. The very important topic of referencing and calibration in CSIA is clearly described. This differs from approaches used in quantitative analysis and is often difficult for the newcomer to comprehend. Examples of successful applications of CSIA in food authenticity, forensics, archaeology, doping control, environmental science, and extraterrestrial materials are included. Applications in isotope data treatment and presentation are also discussed and emphasis is placed on the general conclusions that can be drawn from the uses of CSIA. Further instrumental developments in the field are highlighted and selected experiments are introduced that may act as a basis for a short practical course at graduate level.
Stable Isotopes in Ecology and Environmental Science
Author: Kate LajthaPublisher: Wiley-Blackwell
ISBN: 9780632031542
Category : Science
Languages : en
Pages : 336
Book Description
Stable isotopes are used extensively in all areas of ecology: in studying metabolic processes, to monitor nitrogen turnover in soil, to look at pollution in rainwater, to trace elements through ecosystems, etc. This book, written by two of the leading researchers in the field, will explain the background to stable isotope methodology and discuss the use of the methods in varying ecological situations. An ideal resource for all ecologists using or seeking to use isotopes in their research. A complete guide to the methods, the theory behind them and their advantages and disadvantages. Adopts an ecosystem approach - unlike the competition.

Pages : 532
Book Description
In this authoritative review, leading international researchers explore the growing range of applications of stable isotope techniques for probing and integrating biological processes and palaeoclimatic cycles. The interdisciplinary approach covers a wide range of issues, opportunities and developments, setting interactions with plants in the context of water and nutrient cycles, exchanges with the atmosphere and modelling past and present climate change. This important book will appeal to those requiring an overview of the use of stable isotopes in aquatic, terrestrial and climatic processes and is in tune with current global concerns. In addition postgraduates and research scientists will find an extensive guide to more specialist disciplines, including developing mass spectrometer technologies, compound-specific and cellular-discrimination processes or whole organism and ecosystem responses.

Pages : 414
Book Description
Because our chemical environment affects our physical and mental well-being, it is a matter of increasing concern and is therefore attracting much research effort. This timely collection of essays highlights current developments in the field of environmental toxicology. Chapters analyze the carcinogenic, mutagenic, genotoxic, and neurotoxic effects of both anthropogenic and natural toxins in the soil, air, and water around us, as well as in our workplace and diet. The book also examines the effects of toxins on other organisms, as well as the techniques, policies, and management strategies employed in studying and controlling environmental pollutants. It will be an essential reference to a variety of personnel in environmental studies and public health.

Stable Isotope Techniques in the Study of Biological Processes and Functioning of Ecosystems

ISBN: 940159841X
Category : Science
Languages : en
Pages : 312
Book Description
In the last two decades technological advances in isotope ratio mass spectrometry have been very rapid, opening up new possibilities for analysis of biological and environmental materials. The new instrumentation has facilitated faster analysis of samples via automated sample preparation and multi-isotope analysis of single samples, resulting in considerable cost savings, and enabling access to isotope analysis for many more researchers. These changes are reflected in the rapidly growing international literature on stable isotopes. While there have been some excellent books and review papers aimed at interpreting isotope signals in biology and environmental science, there have been fewer attempts to provide practical tools for researchers making forays into this exciting new arena. This book aims to address this inadequacy by providing a set of practical guidelines for the application of a range of novel and well proven stable isotope techniques to the fields of plant physiological ecology, agriculture, marine ecology and palaeoecology. The book is the outcome of a weeklong workshop held under the auspices of the Cooperative Research Centre for Legumes in Mediterranean Agriculture (CLIMA 1992 - 2000) at The University of Western Australia and the CSIRO Floreat Laboratories, Perth, Western Australia, in February 1999. The workshop was designed to provide practical tools and experiences for researchers and students concerned with how one goes about using stable isotopes in field investigations.
