Abstract
Chromium is a relatively rare, naturally occurring element in the earth's crust. It is an essential nutrient, which can either promote biological functions or toxicological actions due to the major oxidation ststes, Cr (III) and Cr (VI). The body absorbs chromium mainly through the lungs, gastrointestinal trac and skin and excretes via kidneys. Chromium helps in the metabolism of crabohydrates and lipids by reducing the insulin resistance. Chromium levels in food are very low and are not enough for the beneficial actions. Therefore the supplements of chromium are introduced. The amount of chromium supplementation recommended by the U.S. Food and Nutrition Board is 50 to 200 ug per day. The organic forms of chromium are readily and lipophilic. Chromium in trace amounts in the biological samples can be detected by several modern techniuues, such as the atomic absorption spectrometry and the X-ray fluorescence spectrometry.
