Book Description
From the Preface The major change in the format of the fifth edition is the presentation of the book in two volumes, necessitated by the rapidly increasing knowledge of metabolism, interactions, and requirements of trace elements ... The guiding principle was to present the minimum of results that would serve as a logical foundation for the description of the present state of knowledge. Recent results of research were accommodated by devoting new chapters to the subjects "Methodology of Trace Element Research" and "Quality Assurance for Trace Element Analysis" and by expanding the discussion of lithium and aluminum in separate, new chapters. The first two subjects are of outstanding importance as determinants of future progress. The concern for the quality of analytical data motivated the authors of the individual chapters to review critically and, where necessary, revise analytical data presented in the previous editions. The rapid progress of trace analytical methodology since the mid-1970s has changed what had been accepted as normal for the concentrations of many trace elements in tissues and foods. The new data reflect the present state of the art in trace element analysis, but they may be subject to future revision.

Book Description
Trace Elements in Human and Animal Nutrition, Fourth Edition, explores the physiological roles of trace elements in human and animal nutrition. It looks at the needs, tolerances, and interactions of trace elements with each other and with other nutrients and compounds, and it explores how deficient, toxic, or imbalanced intakes of such elements lead to biochemical and pathological changes. It also describes ways of diagnosing and addressing such aberrant intakes of trace elements, along with their principal sources. Organized into 20 chapters, this volume begins with an overview of the nature of trace elements and their mode of action, including iron, copper, molybdenum, cobalt, nickel, manganese, zinc, cadmium, chromium, iodine, selenium, fluorine, mercury, vanadium, silicon, lead, and arsenic. It then discusses the presence of these elements in animal tissues and fluids, along with their metabolism, functions, and toxicity. It also considers other elements, such as aluminum, antimony, barium, boron, bromine, germanium, lithium, rubidium, silver, strontium, tin, titanium, and zirconium. The book concludes with an analysis of the interrelationships among soil, plants, and animals. This book should be a valuable resource for students and chemists.
