Is selenium found in the soil?
Is selenium found in the soil?
Selenium is a naturally occurring element found in rocks, soil and water. Selenium weathered from rocks under alkaline and oxidizing conditions form selenates, which are highly toxic. Selenite and selenates are produced by soil microorganisms from less soluble forms of selenium.
Is Texas selenium poor?
Texas water sources were found to be poor in selenium, except for the Panhandle and the West Texas regions, where soil consists of erosion products from the selenium-rich Rocky Mountains.
Who absorbs selenium from soil?
Selenium is commonly found as water-soluble selenate in well-aerated, alkaline soils and is readily absorbed via the sulfate transporter system by plants, as compared with very poor uptake of selenides and selenite, which may predominate in acidic soils.

Loss of selenium rich soil has reduced the dietary availability of selenium, thus increasing the deficiency of this micronutrient worldwide [18]. India is a vast country with wide geographical soil status. In one study, the northern part of India was reported to have normal levels of soil selenium [19] .

How much selenium is there in the soil?
Local agricultural extension services usually maintain soil maps that indicate selenium. levels. Because selenium levels can vary greatly within an area, testing the soil’s selenium content is recommended.

Who are more likely to have higher selenium levels?
Men have slightly higher serum selenium levels than women, and whites have higher levels than African Americans [ 19-21 ]. Selenium intakes and serum concentrations in the United States and Canada vary somewhat by region because of differences in the amounts of selenium in soil and in local foods consumed [ 6, 22 ].
