Book Description
Trace element analysis has a key role to play in quality control of food and diet. This timely book introduces the subject in a practical way - from sampling and the techniques available for trace analysis, to procedures for specific elements and data analysis. Beginning with a brief introduction and discussion of statistical evaluation of data, the subsequent chapter looks at trace analysis in general, with its essentials and terminology. Another section introduces sampling and preparation of foodstuffs such as wheat, potato, vegetables and milk. This is followed by descriptions of the various spectrometric techniques (atomic absorption, atomic emission, atomic fluorescence) that are available. Plasma techniques for both optical emission and mass spectrometry are presented, as are nuclear activation analysis and X-ray methods. A comparison of the various analytical techniques is provided, and a separate chapter handles speciation analysis. Finally, procedures for determining essential and toxic elements such as arsenic, iron, selenium and zinc are suggested, using several recent references. Detailed explanations and a simple format will appeal to laboratory technicians and graduate students, as well as more experienced researchers. Comprehensive coverage, coupled with illustrations and a guide to relevant literature and manufacturers, will make Trace Element Analysis of Food and Diet a valuable source of information for anyone working on analysis of trace elements in food, diet or other biological or environmental samples - particularly food engineers, agricultural scientists and government testing agency employees.

Book Description
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
The ongoing progress of science has shown that it is important for analytical scientists to determine not only the presence of particular elements, but also their species. There are many fields where this is applicable, and where there are a number of topics to be addressed. Developing separation and measurement systems for the many element species has tested the resourcefulness of analytical chemists over recent decades. A product of the EU sponsored Speciation 21 Network, this book presents a detailed review of the state-of-the-art of speciation issues in the occupational health, food and environment sectors, along with the main conclusions arising from discussions held during expert meetings. Topics covered include mercury and organotin compounds in the environment; factors affecting the health of workers; the importance of speciation of trace elements for health, and subsequent metabolism in the body; analytical methodologies; risk assessment; and legislation. Trace Element Speciation for Environment, Food and Health provides an insight into applied research in the speciation field and how it has become so important in all the fields represented. With its comprehensive coverage, it will be of particular interest to researchers in industry and academia, as well as government agencies and legislative bodies.

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.

Book Description
Mineral elements are found in foods and drink of all different types, from drinking water through to mothers’ milk. The search for mineral elements has shown that many trace and ultratrace-level elements presented in food are required for a healthy life. By identifying and analysing these elements, it is possible to evaluate them for their specific health-giving properties, and conversely, to isolate their less desirable properties with a view to reducing or removing them altogether from some foods. The analysis of mineral elements requires a number of different techniques – some methods may be suitable for one food type yet completely unsuited to another. The Handbook of Mineral Elements in Food is the first book to bring together the analytical techniques, the regulatory and legislative framework, and the widest possible range of food types into one comprehensive handbook for food scientists and technologists. Much of the book is based on the authors’ own data, most of which is previously unpublished, making the Handbook of Mineral Elements in Food a vital and up-to-the-minute reference for food scientists in industry and academia alike. Analytical chemists, nutritionists and food policy makers will also find it an invaluable resource. Showcasing contributions from international researchers, and constituting a major resource for our future understanding of the topic, the Handbook of Mineral Elements in Food is an essential reference and should be found wherever food science and technology are researched and taught.

Book Description
"This book deals with trace elements, such as cobalt, copper, iron, manganese, selenium and zinc which are essential to modern animal nutrition, but are increasingly detrimental to soil and water quality in today's globalized production. The goal in finding a sustainable balance between trace element use in animal nutrition and its impact on the environment is addressed by focussing on the following questions: - What is the trace element flow on farm, regional or national scale and which tools are available to influence the flow? - What are today's and future soil and water quality in regards to trace minerals? - What are the trace mineral loading limits in soil and water from a health and legal standpoint? - Which technologies exist to modify slurry trace element contents? - What is today's knowledge on quantitative and qualitative trace element requirements and recommended supplementation for ruminants, swine, poultry, fish and crustaceans? - What is trace element bioavailability and how can it be determined? - To which extent are trace minerals related to immune response? - What are the future issues to be addressed in trace element nutrition? This book contains the peer-reviewed papers of the first International Symposium on Trace Elements in Animal Production Systems. It is a valuable resource for researchers and professionals in the life sciences of animal nutrition, soil and water quality, for actors in the feed industry and policy making."
