Chromium Excess
Introduction
Chromiumexcess can result from exposure tochromiumin the workplace. (See also Overview of Minerals .) Chromiumenablesinsulin(which controls blood sugar levels) to function and helps in the processing (metabolism) and storage of carbohydrates, protein, and fat. Chromiumsupplements do not enhance muscle size or strength. Small amounts ofchromiumtaken by mouth are not harmful (nontoxic). In the workplace, people may be exposed to a different, harmful (toxic) form ofchromium. This form results from industrial pollution. This form may irritate the skin, cartilage of the nose, lungs, and digestive tract and may cause lung cancer.
