Selenium,from the Greek meaning 'moon'
Keeping with the theme of the letter "S",September's Metal of the Month isselenium.Selenium takes its name from the Greek meaning ‘moon',and it usually exists in two forms: a red powder or a silvery metal.Native elemental selenium is actually quite rare and it is most often found in minerals and ores.
It has photovoltaic and photoconductive properties,and is often used in solar cells,photoelectric cells,and photocopiers.It is used in the manufacturing of glass and stainless steel.Selenium is also an active ingredient in anti-dandruff shampoos!
Brazil nuts contain a high dietary source of selenium
Though it is toxic in excess,selenium is an essential trace element for humans,and is found in a number of amino acids,and is therefore thought to have a role in enzymatic reactions and the function of the thyroid gland.Brazil nuts are one of the richest dietary sources of selenium;it can also be found in other nuts,cereals meat,mushrooms and eggs.
