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 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 ...

The major theme of this book is analytical approaches to trace metal and speciation analysis in biological specimens. The emphasis is on the reliable determination of a number of toxicologically and environmentally important metals. It is essentially a handbook based on the practical experience of each individual author. The scope ranges from sampling and sample preparation to the application of various modern and well-documented methods, including quality assessment and control and statistical treatment of data. Practical advice on avoiding sample contamination is included. In the first part, the reader is offered an introduction into the basic principles and methods, starting with sampling, sample storage and sample treatment, with the emphasis on sample decomposition. This is followed by a description of the potential of atomic absorption spectrometry, atomic emission spectrometry, voltammetry, neutron activation analysis, isotope dilution analysis, and the possibilities for metal speciation in biological specimens. Quality control and all approaches to achieve reliable data are treated in chapters about interlaboratory and intralaboratory surveys and reference methods, reference materials and statistics and data evaluation. The chapters of the second part provide detailed information on the analysis of thirteen trace metals in the most important biological specimens. The following metals are treated in great detail: Aluminium, arsenic, cadmium, chromium, copper, lead, selenium, manganese, nickel, mercury, thallium, vanadium and zinc. The book will serve as a valuable aid for practical analysis in biomedical laboratories and for researchers involved with trace metal and species analysis in clinical, biochemical and environmental research.

"A spark source mass spectrometer that uses electronic detection and a dedicated data analysis system was applied to a survey type trace analysis for chemical elements. Errors in the data system software were identified and corrected. Modifications to the system permit identification and quantitation of 72 elements at the aprt per billion level in water samples.""--P ii.

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.
