Because of their photosynthetic activity, plants represent the most important form of life on earth, and thus provide a rich and important source for investigation. By studying the levels of elements such as lead, cadmium and mercury in plants, vital information on background concentrations of such elements in the environments can be obtained. The growth in the use of instrumental multi-element techniques, such as neutron activation, X-ray fluorescence and atomic emission spectroscopy in the analysis of plant samples has led to significant advances in our ability to determine accurately the quantities of such elements present in plant samples. Instrumental Element and Multi-Element Analysis of Plant Samples: Methods and Applications presents the latest key advances that have taken place in a wide range of instrumentation, such as improvements in detection limits, reproducibility and accuracy. Potential problem areas such as representative sampling, sampling processes and accuracy are discussed in detail. Although concentrating on the analysis of plant samples, the book also considers general issues associated with multi-element analysis of environmental analysis in general. Instrumental Element and Multi-Element Analysis of Plant Samples: Methods and Applications will be of great interest to all those working in environmental analysis, particularly in the area of plant sample analysis. Its highly practical and inter-disciplinary approach will make it indispensable to chemists, biochemists, biologists and geologists interested in these areas.

This volume discusses major areas of primary concern for the understanding of the complexity associated with ecological trace element research. These include sources and fates of trace elements; analytical techniques; and the distribution of trace elements in biota and soil and sediment reservoirs. Case studies, field work and laboratory studies intensively discussed in this volume are useful to enhance our knowledge about processes related to the biological response of trace metal stress under realistic environmental conditions.

This paper describes possibilities of using instrumental multielement methods to answer various ecological questions. Emphasis is placed on the ecosystem-related approach and thus comparison of various ecosystems and compartments of these. The basis for this is a project by the Internationa Union of Biological Sciences (IUBS) aimed at establishing"element concentration cadasters in ecosystems" (ECCEs). In principle, the intention is to collect data on the worldwide distribution of individual elements and element species in various ecosystems ...

This book is written for researchers and students interested in the function and role of chemical elements in biological or environmental systems. Experts have long known that the Periodic System of Elements (PSE) provides only an inadequate chemical description of elements of biological, environmental or medicinal importance. This book explores the notion of a Biological System of the Elements (BSE) established on accurate and precise multi-element data, including evolutionary aspects, representative sampling procedures, inter-element relationships, the physiological function of elements and uptake mechanisms. The book further explores the concept Stoichiometric Network Analysis (SNA) to analyze the biological roles of chemical species. Also discussed is the idea of ecotoxicological identity cards which give a first-hand description of properties relevant for biological and toxicological features of a certain chemical element and its geo biochemically plausible speciation form. The focus of this book goes beyond both classical bioinorganic chemistry and toxicology.

Instrumental Methods for Determining Elements reviews and compares the most commonly used instrumental methods of elemental analysis, including atomic absorption and emission spectrometry, electrochemistry, potentiometry, chromatography, x-ray fluorescence, and combustion techniques. A brief introduction to the theory of these techniques is presented along with the factors that are important in selecting the proper technique for an application. Advantages and limitations of each instrumental method are detailed enabling the analyst to compare different techniques before choosing the most reliable and cost effective technique for their needs. Because of the wide variety of choices in the available instrumentation to perform various types of analyses, Instrumental Methods for Determining Elements is an essential resource for analytical chemists and chemical engineers who need to decide which method to use or which instrumentation to purchase.

Following the collection of a sample, every analytical chemist will agree that its subsequent preservation and processing are of paramount importance. The availability of high performance analytical instrumentation has not diminished this need for careful selection of appropriate pretreatment methodologies, intelligently designed to synergistically elicit optimum function from these powerful measurement tools. Sample Preparation for Trace Element Analysis is a modern, comprehensive treatise, providing an account of the state-of-the art on the subject matter. The book has been conceived and designed to satisfy the varied needs of the practicing analytical chemist. It is a multi-author work, reflecting the diverse expertise arising from its highly qualified contributors. The first five chapters deal with general issues related to the determination of trace metals in varied matrices, such as sampling, contamination control, reference materials, calibration and detection techniques. The second part of the book deals with extraction and sampling technologies (totaling 15 chapters), providing theoretical and practical hints for the users on how to perform specific extractions. Subsequent chapters overview seven major representative matrices and the sample preparation involved in their characterization. This portion of the book is heavily based on the preceding chapters dealing with extraction technologies. The last ten chapters are dedicated to sample preparation for trace element speciation. - First title to provide comprehensive sample preparation information, dealing specifically with the analysis of samples for trace elements. - The 39 chapters are authored by international leaders of their fields.
