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.
