Selenium is mineral that is found in soil and occurs naturally in certain foods (such as whole grains, Brazil nuts, sunflower seeds, and seafood). Selenium is not produced in the body, but it is needed for proper thyroid and immune system function. Selenium is used to treat or prevent selenium . The former Kesterson Reservoir in the San Joaquin Valley provides a cautionary tale of the environmental impacts of agricultural drainage.. Completed in by the Bureau of Reclamation, Kesterson included 12 evaporation ponds for irrigation drainage water. The reservoir, a part of the San Luis National Wildlife Refuge, was an important stopping point for waterfowl.
The disposal of this often-contaminated water continues to be a challenge in California, with the environmental effects of selenium and other drainage-related elements changing the course of drainage planning. Agricultural Drainage Environmental Impacts Overview. Selenium in Plant and Animal Nutrition H. F. Mayland Agricultural Research Service, U.S. Department of Agriculture Kimberly, Idaho INTRODUCTION Selenium (Se), while not required by plants, is an essential trace element for adequate nutrition and health for fish, birds, animals, and humans.
Selenium is a naturally occurring, solid substance that is widely but unevenly distributed in the earth's crust. It is also commonly found in rocks and soil. Selenium, in its pure form of metallic gray to black crystals, is often referred to as elemental selenium or selenium dust. Elemental selenium is commercially produced, primarily as a by-product of copper refining. The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. The environmental impact of agriculture varies based on the wide variety of agricultural practices employed around the world. Ultimately, the environmental impact depends on the production .

Selenium in Agriculture and the Environment: Proceedings of a Symposium, Issues L. Jacobs, American Society of Agronomy. Division A-5, Soil Science Society of America American Society. Discusses the biochemical and geological cycling of selenium (Se), its worldwide distribution, and the factors controlling its fate and transport within and between major environmental media.
Selenium (Se) is both beneficial and toxic to animals, plants, and humans. Consequently, it is imperative to know its concentration in the environment and to understand the processes controlling its distribution.
Determinations of Se concentrations in a variety of materials indicate that Se is widely distributed throughout the environment. The roles of selenium as enhancer and inhibitor of plant growth in various agricultural crops are discussed here with recent updates.
Biofortification of some crops with Se using agronomic and genetic approaches is being explored to cultivate them in the regions having Se-deficiency in foods. Selenium (Se 34 79) is a metalloid which is close to sulfur (S) in terms of properties.
The Se concentration in soil varies with type, texture and organic matter content of the soil and with rainfall. Its assimilation by plants is influenced by the physico-chemical properties of the soil (redox status, pH and microbial activity).
Selenium in Agriculture and the Environment Soil Science(2), February The occurrence of selenium in the environment from soil to food systems is discussed. The most promising and important nanotechnology applications in agriculture; and nano-selenium particles production, agricultural nanotechnology and its use in sustainable development will also be highlighted.
Contributors from 22 countries explored the connections and inter-relationships between selenium in the environment, agriculture, human and animal health, and molecular and biochemistry processes to complete Selenium in the Environment and Human Health containing 90.

– Selenium can be beneficial but it can also be toxic, particularly to egg-laying vertebrates (fish, birds, amphibians, reptiles). Concentrations of selenium in the environment are increasing globally as a result of mining, power generation, agriculture, and animal husbandry.
Discusses the biochemical and geological cycling of selenium (Se), its worldwide distribution, and the factors controlling its fate and transport within and between major environmental media, presenting a global assessment of selenium's complex environmental behaviour. The focus of this work is upon Se management and remediation strategies.
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.
Written as a complement to the definitive work, Selenium in the Environment (Marcel Dekker, Inc.), this timely resource presents basic and the most recent applied research developments in selenium remediation - emphasizing field investigations as well as covering topics from analytical methods and modeling to regulatory aspects from federal and state perspectives.
Selenium release to the environment during coal burning for power generation can be direct during combustion or indirect from disposal of solid combustion waste (i.e., fly ash).
Large-scale land disturbance is associated with mountaintop coal mining and waste-rock management in the southern and central Appalachian Mountains. Discusses the biochemical and geological cycling of selenium (Se), its worldwide distribution, and the factors controlling its fate and transport within and between major environmental media, presenting a global assessment of selenium's complex environmental behaviour.
The focus of this work is upon Se management and remediation strategies.The natural soluble inorganic forms, selenite and selenate, account for the majority of total global selenium [ 12 ]. The ultimate source of all Se is the rocks and soils of our terrestrial environment.
Most soils contain from to 2 µg/g of Se, but this is not evenly distributed.Selenium In Food And Health by Conor Reilly, Selenium In Food And Health Books available in PDF, EPUB, Mobi Format.
