Book Description
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.

Book Description
Despite the development of innovative new analytical techniques for biological trace element research, today's trace element investigators face formidable obstacles to obtaining reliable data. This complete reference identifies and assesses the challenges the analyst encounters at each stage of an analysis, and discusses the effects of various techniques on the sample. Three internationally recognized scientists and authors consider the effects of the numerous collection, storage, and sample preparatory techniques used in sample analysis. Proper analytical quality control, including such critical factors as sampling and sample preparation, specimen preservation and storage, and ashing, is examined. The book also looks at sample preparation methods unique to various instruments and speciation chemistry issues, and examines the link between chemical analysis and specimen banking. A previously unrecognized source of error, presampling factors, is also discussed.

Book Description
This volume is a comprehensive introduction to the analysis, binding, uptake, metabolism, kinetics, modeling, distribution, occurrence, toxicity and chelation of metals and fluoride in the body, with special reference to mineralized tissues. Both toxic and relatively harmless polyvalent cations and anions are considered. Included are some which are stable, and others which are radioactive. While a number are essential trace elements, others have no known metabolic role. Most chapters are concerned with the uptake of bone-seeking ions by the living skeleton, but aspects of the post-mortem uptake of metals and the process of fossilization are also considered. Highlighted are the utility of modern analytical techniques and the more important bone-seeking elements including aluminum, lead, cadmium, fluorine and the radioactive heavy metals including uranium and plutonium. This important publication is of particular value to those in the fields of biochemistry, radioactive waste, geology, physiology, dentistry, orthopedics, radiology and nuclear medicine, urology, industrial hygiene, pharmacology, anthropology, paleontology, and archeology.

Book Description
"One should rather go horne and mesh a net than jump into the pond and dive far fishes" (Chinese proverb) Recognizing the precise analytical question and planning the analysis according ly is certainly the first prerequisite for successful trace and ultratrace determina tions. The second prerequisite is to select the method appropriate to the analyti cal specification. The method itself consists of a set of available tools. The third prerequisite is that analysts and operators know the methods weH enough to enjoy challenging themselves as weH as the methods and are rewarded by the joy of high-quality data, fast and economical results and the conviction of having the analytical job under control. This skill is known among analysts or operators working with an exciting new and sometimes complicated analytical technique but is gradually lost on ce a technique becomes "mature" and a routine tool. Unfortunately, laboratory managers often do not allow sufficient training time for their analysts and technicians for "routine" techniques and thus miss an opportunity for motivating their co-workers and obtaining the full benefit of the equipment. Graphite furnace atomic absorption spectrometry (AAS) is one of the mature analytical techniques wh ich is seen as a routine method in most laboratories. More than 10,000 furnaces are operated in elemental trace and ultratrace analy ses in laboratories around the world today.

Book Description
The papers and reviews in the present volume are in part regular contributions submitted for publication in Biological Trace Element Research, and in part invited papers from participants of the International Symposium "Present Status and Perspectives of Sele nium in Biology and Medicine," held on May 2 and 3, 1987, at the Eu ropean Academy, Nonnweiler /Trier, FRG. The Symposium focused on ecological and biomedical aspects of selenium with emphasis on the manifestations of selenium deficiency in different countries, the distribution of selenium in human organs and body fliuds, the roles of selenium in health and disease, its anti carcinogenic action, effects of supplementation, and therapeutic applications. Organized jointly by the International Association of Bioinor ganic Scientists and BioSynopsia, a Nonprofit Subsidiary of the Tech nology Center, Stuttgart, the scientific board consisted of Professors W. Hartfiel, Bonn, FRG, G.N. Schrauzer, La Jolla, CA, USA, and H. Zumkley, Muenster, FRG.

Book Description
Increasing the accumulation of aluminum in the bone (body) in cases of renal osteodystrophy may influence the histopathologic aspect of the bones. Alumi num blunts the effect of increased PTH secretion and favours the genesis of osteoid. That means, in cases of renal failure combined with aluminum accumulation, a relatively low bone tunover is found and no fibrosis of the bone marrow. Furthermore the amount of osteoid is increased. This means that there is evidence of osteomalacia especially when the latter is defined as an increased amount of osteoid covered with a relatively low number of cubic osteoblasts. To a certain extent the effect of aluminum accumulation is comparable to the effect of PTX. Treatment with DFO may normalize the bone, although not necessarily with a concomittant disappearance of alumi num from the bone. The presence of aluminum in the bone can be suggested by routine histologic investigation of the bone and can be made rather probably by the aluminum staining combined with iron-staining, but can only be proven by more advanced techniques like ET AAS and LAMMA.
