Selenium is an important micronutrient in humans and animals, despite its toxicity at high concentrations. This first chapter performs a thorough review of selenium bioavailability in food stuffs and human diet. The second chapter reviews the selenium essentiality and toxicity, the aspects related to the selenium dietary supplementation and its daily consumption. The third chapter describes the status of selenium and their metabolites in an antiretroviral therapy context. The next chapter looks at selenium supplementation and autoimmune thyroid diseases. Next, the authors address the association between diabetes type-2 and its levels in serum related to nutritional habits. Then, the preparation of nanosystems based on zero-valent selenium nanoparticles since this essential trace elements carries unique characteristics is explored. Finally, the prospects of using nanoparticles of elementary selenium as a nutrition source are discussed.

Abstract: An authoratitive reference text for nutritionists, clinicians, and other health professionals provides an extensive review of the most pertinent scientific literature dealing the basic aspects of the present understanding of the roles of selenium (Se) in nutrition and health. Following a brief discussion of the chemistry and analysis of Se, attention is focused on: the occurrence of Se in the environment and in foods and feeds; the bioavailability of Se in foods and feeds; Se uptake, metabolism, a nd excretion; the biological functions of Se; Se deficiency diseases in laboratory animals and livestock; the role of Se in human nutrition and health; its role in immunity and infection; associations between Se and cancer; and the effects of Se toxicity in animals and humans. Numerous detailed data tables and illustrations are presented throughout the text, and literature citations are appended to each chapter.

Many health benefits have been attributed to selenium that include preventing various forms of cancer (e.g., colon cancer, prostate cancer, lung cancer and liver cancer), heart disease and other cardiovascular and muscle disorders, inhibiting viral expression, delaying the progression of acquired immunodeficiency syndrome (AIDS) in human immunodeficiency virus (HIV)-positive patients, slowing the aging process, and having roles in mammalian development, including male reproduction and immune function. The purpose of the book is the same as the first two volumes which is to bring an up to date status of current research in the rapidly developing selenium field centered around the health benefits attributed to this element and how this element makes its way into protein.

The contamination of environment and water resources by Selenium (Se) and its oxyanions from various sources are emerging contaminants of significant health and environmental concern. The primary sources include agricultural drainage water, mine drainage, residues from fossil fuels, thermoelectric power plants, oil refineries, and metal ores. Various methods and technologies have been developed which focus on the treatment of selenium-containing waters and wastewater. High concentrations of selenium in water cause various adverse impact to human health, such as carcinogenic, genotoxic, and cytotoxic effects. But in the lower concentrations, it is a useful constituent of the biological system. The range between toxicity and deficiency of selenium is minimal (40 to 400 μg per day), due to its dual nature. Selenium Contamination in Water contains the latest status and information on selenium’s origin, its chemistry and its toxicity to humans. The book represents a comprehensive and advanced reference book for students, researchers, practitioners, and policymakers in working in the field of metalloids, in particular selenium. A special emphasis is given on its geological distribution, monitoring techniques, and remedial technologies. As such, the authors critically analyze the various techniques used for the monitoring and removal of selenium from water. Featuring chapters arranged according to the major themes of the latest research, with specific case-studies from industrial experiences of selenium detection and removal, Selenium Contamination in Water will be particularly valued by researchers, practitioners, and policymakers in working in the field of metalloids including selenium.
