Diet and Health examines the many complex issues concerning diet and its role in increasing or decreasing the risk of chronic disease. It proposes dietary recommendations for reducing the risk of the major diseases and causes of death today: atherosclerotic cardiovascular diseases (including heart attack and stroke), cancer, high blood pressure, obesity, osteoporosis, diabetes mellitus, liver disease, and dental caries.
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.

The remarkable development of molecular biology has had its counterpart in an impressive growth of a segment of biology that might be described as atomic biology. The past several decades have witnessed an explosive growth in our knowledge of the many elements that are essential for life and maintenance of plants and animals. These essential elements include the bulk elements (hydro gen, carbon, nitrogen, oxygen, and sulfur), the macrominerals (sodium, potas sium, calcium, magnesium, chloride, and phosphorus), and the trace elements. This last group includes the ultra trace elements and iron, zinc, and copper. Only the ultratrace elements are featured in this book. Iron has attracted so much research that two volumes are devoted to this metal-The Biochemistry of Non-Heme Iron by A. Bezkoravainy, Plenum Press, 1980, and The Biochemistry of Heme Iron (in preparation). Copper and zinc are also represented by a separate volume in this series. The present volume begins with a discussion of essentiality as applied to the elements and a survey of the entire spectrum of possible required elements.
Trace Elements in Human and Animal Nutrition focuses on trace elements and their nutritional significance to humans and domestic animals. The trace elements covered include copper, molybdenum, iron, cobalt, nickel, zinc, manganese, iodine, fluorine, selenium, aluminum, arsenic, barium, strontium, boron, bromine, silicon, and vanadium. This book is organized into 13 chapters and begins with an overview of the trace element concept, the mode of action of trace elements, and the use of spectrochemical methods for the detection and estimation of t ace metals in biological materials. The next chapters explore in more detail the importance of trace elements in human and animal nutrition, touching on topics such as absorption and excretion in the body, deficiency, and toxicity. The book concludes by discussing the interrelationships between plants, man and his domestic animals, and the soil, with emphasis on the link between trace element deficiencies and health. An account of factors influencing the trace element contents of plants is also given. Finally, qualitative and quantitative differences in the trace element requirements of plants and animals are described. This book is intended for nutritionists and those who plan to specialize in nutrition.
Trace elements occur naturally in soils and some are essential nutrients for plant growth as well as human and animal health. However, at elevated levels, all trace elements become potentially toxic. Anthropogenic input of trace elements into the natural environment therefore poses a range of ecological and health problems. As a result of their persistence and potential toxicity, trace elements continue to receive widespread scientific and legislative attention. Trace Elements in Soils reviews the latest research in the field, providing a comprehensive overview of the chemistry, analysis, fate and regulation of trace elements in soils, as well as remediation strategies for contaminated soil. The book is divided into four sections: • Basic principles, processes, sampling and analytical aspects: presents an overview including general soil chemistry, soil sampling, analysis, fractionation and speciation. • Long-term issues, impacts and predictive modelling: reviews major sources of metal inputs, the impact on soil ecology, trace element deficient soils and chemical speciation modelling. • Bioavailability, risk assessment and remediation: discusses bioavailability, regulatory limits and cleanup technology for contaminated soils including phytoremediation and trace element immobilization. • Characteristics and behaviour of individual elements Written as an authoritative guide for scientists working in soil science, geochemistry, environmental science and analytical chemistry, the book is also a valuable resource for professionals involved in land management, environmental planning, protection and regulation.

This volume, containing the proceedings of the tenth of the highly successful TEMA meetings, presents recent progress in the research on the functional role and metabolism of trace elements, and new developments in the understanding of molecular and cellular biology.
Over the past few decades, tremendous progress in analytical facilities allowed for the decreasing detection limits of trace element (TE) analysis in a large number of organic and inorganic matrices. This was especially true for freshwater aquatic systems, where direct measurements of more than forty trace elements have become possible provided that necessary precautions against pollution are made and required sample preparation protocol is maintained. Therefore, analyses of both liquid (water) and solid (biomass, sediments, soils, and aerosol particles) compartments of the landscape continuum allowed for a new perspective on biogeochemical factors of trace elements in a large panel of terrestrial environments. However, among all Earth biomes, the Arctic and subarctic regions are certainly less studied from a trace element biogeochemical view point.This book adresses a variety of geochemical and biogeochemical issues of trace element behavior in soils, waters, and plants across the world, from Eastern Europe to Siberian subarctic and Arctic islands. It presents a synthesis of state-of-the-art studiesusing precise analytical techniqueson trace element concentrations, fractionation, and migration in the main biogeochemical reservoirs of the Northern Hemisphere. This book combines chapters on trace elements in soils, plants, soil waters, lakes, rivers and their estuarine zones, and atmopsheric aerosols. As such, it provides a comprehensive view of current TE biogeochemistry and can serve as a reference compilation of available information for judging future changes in trace element biogeochemistry for terrestrial environments influenced by climate warming or increasing anthropogenic pollution.
