This book covers many facets of plant selenium (Se) accumulation: molecular genetics, biochemistry, physiology, and ecological and evolutionary aspects. Broader impacts and applications of plant Se accumulation also receive attention. Plant Se accumulation is very relevant for environmental and human health. Selenium is both essential at low levels and toxic at high levels, and both Se deficiency and toxicity are problems worldwide. Selenium can positively affect crop productivity and nutritional value. Plants may also be used to clean up excess environmental Se. Selenium in plants has profound ecological impact, and likely contributes to Se movement in ecosystems and global Se cycling.

Selenium is arguably the naturally occurring trace element of greatest concern worldwide. In excessive amounts it can lead to toxicosis and teratogenesis in animals, while the impact of selenium deficiency can be even more significant. Contributors from 22 countries explored the connections and inter-relationships between selenium in the environmen

This book describes the role of trace elements in health and longevity, pursuing a biogerontological approach. It offers essential information on the impact of trace elements on molecular and physiological processes of aging, and on their impact on health in connection with aging. The major topics covered in its 11 chapters, each dedicated to a specific trace element or mineral, are: a) Role of the element in species longevity, b) Recommended intake for longevity in animal species and in the elderly, c) Deficiency and age-related disease, d) Excess/toxicity and age-related disease, and e) Interactions with drugs prescribed in the elderly. Clinical, animal and other laboratory models of interest in aging are included, which enable a more in-depth analysis to be made. The respective chapters are a mixture of overviews and more in-depth reviews in which the mechanisms of aging are described from the point of view of their specific interactions with trace elements and minerals.

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.

Selenium: Geobotany, Biochemistry, Toxicity, and Nutrition focuses on the properties, characteristics, reactions, applications, chemistry, and transformations of selenium. The book first offers information on the geological distribution of selenium, including the formation of seleniferous soils, chemical forms of selenium in soils, selenium in water, selenium on the sea floor and in sea water, and geobotany. The text then takes a look at selenium indicator in plants and accumulation of selenium by plants. Discussions focus on selenium accumulations in indicator plants; selenium accumulation in farm crops and native grasses; factors that influence selenium accumulation in plants; and identification of indicators by germination tests. The manuscript elaborates on selenium poisoning in animals and prevention and control of selenium poisoning. Acute selenium poisoning, chronic selenium poisoning by inorganic selenium, and recognition of poisonous range plants are also discussed. The text also examines selenium in nutrition and the chemistry of selenium. The publication is a valuable source of data for readers interested in the study of selenium.

The term "soil health" refers to the functionality of a soil as a living ecosystem capable of sustaining plants, animals, and humans while also improving the environment. In addition to soil health, the environment also comprises the quality of air, water, vegetation, and biota. The health of soil, plants, animals, people, and the environment is an indivisible continuum. One of the notable ramifications of the Anthropocene is the growing risks of decline in soil health by anthropogenic activities. Important among these activities are deforestation, biomass burning, excessive soil tillage, indiscriminate use of agrochemicals, excessive irrigation by flooding or inundation, and extractive farming practices. Soil pollution, by industrial effluents and urban waste adversely impacts human health. Degradation of soil health impacts nutritional quality of food, such as the uptake of heavy metals or deficit of essential micro-nutrients, and contamination by pests and pathogens. Indirectly, soil health may impact human health through contamination of water and pollution of air. This book aims to: Present relationships of soil health to human health and soil health to human nutrition. Discuss the nexus between soil degradation and malnourishment as well as the important links between soil, plant, animal and human health. Detail reasons oil is a cause of infectious diseases and source of remedial measures. Part of the Advances in Soil Sciences series, this informative volume covering various aspects of soil health appeals to soil scientists, environmental scientists and public health workers.
