Chromium is a naturally occurring element found in rocks, animals, plants, soil, and in volcanic dust and gases. Chromium is present in the environment in several different forms. The most common forms are chromium (0), chromium (III), and chromium (VI). No taste or odor is associated with chromium compounds.
Chromium (III) oxide is also referred to as chromic oxide. It is commonly employed as a marker in various digestion assays conducted on animals. Chromium (III) oxide is mainly used as a green pigment in paints, inks and ceramics. On a commercial scale, it is synthesized by the reduction of sodium chromate with sulfur. [1]
