but exists mainly in the Cr(III) and Cr(VI) states; Cr(III) is the most stable. Hexavalent chromium compounds have varying physical and chemical properties. Most Cr(VI) compounds are solids; chromyl chloride is a liquid. Their properties include corrosion-resistance, durability, and hardness. Sodium dichromate is the most common chromium chemical from which other Cr(VI) compounds are produced. Examples of other Cr(VI

Chromium is a very hard gray solid with a metallic luster. (NTP, 1992)|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) occurs naturally in the environment and is an essential nutrient. Chromium(VI) and chromium(0) are generally produced by industrial processes.The metal chromium, which is the chromium(0) form, is used for making steel. Chromium(VI) and chromium(III) are used for chrome plating, dyes and pigments, leather tanning, and wood preserving.|Chromium atom is a chromium group element atom that has atomic number 24. It has a role as a micronutrient. It is a chromium group element atom and a metal allergen.|Chromium is a transition element with the chemical symbol Cr and atomic number 24 that belongs to Group 6 of the periodic table. It is used in various chemical, industrial and manufacturing applications such as wood preservation and metallurgy. The uses of chromium compounds depend on the valency of chromium, where trivalent Cr (III) compounds are used for dietary Cr supplementation and hexavalent Cr (VI) compounds are used as corrosion inhibitors in commercial settings and are known to be human carcinogens. Humans can be exposed to chromium via ingestion, inhalation, and dermal or ocular exposure. Trivalent chromium (Cr(III)) ion is considered to be an essential dietary trace element as it is involved in metabolism of blood glucose, regulation of insulin resistance and metabolism of lipids. Clinical trials and other studies suggest the evidence of chromium intake improving glucose tolerance in patients with Type I and II diabetes, however its clinical application in the standard management of type II diabetes mellitus is not established. Chromium deficiency has been associated with a diabetic-like state, impaired growth, decreased fertility and increased risk of cardiovascular diseases. According to the National Institute of Health, the daily dietary reference intake (DRI) of chromium for adult male and non-pregnant female are 35 μg and 25 μg, respectively. Chromium picolinate capsules may be used as nutritional adjuvant in patients with or at risk of type 2 diabetes mellitus (T2DM) to improve blood sugar metabolism and stabilize the levels of serum cholesterol. Chromium chloride is available as an intravenous injection for use as a supplement to intravenous solutions given for total parenteral nutrition (TPN).|Chromium occurs in the environment primarily in two valence states, trivalent chromium (Cr III) and hexavalent chromium (Cr VI). Exposure may occur from natural or industrial sources of chromium. Chromium III is much less toxic than chromium (VI). The respiratory tract is also the major target organ for chromium (III) toxicity, similar to chromium (VI). Chromium (III) is an essential element in humans. The body can detoxify some amount of chromium (VI) to chromium (III). The respiratory tract is the major target organ for chromium (VI) toxicity, for acute (short-term) and chronic (long-term) inhalation exposures. Shortness of breath, coughing, and wheezing were reported from a case of acute exposure to chromium (VI), while perforations and ulcerations of the septum, bronchitis, decreased pulmonary function, pneumonia, and other respiratory effects have been noted from chronic exposure. Human studies have clearly established that inhaled chromium (VI) is a human carcinogen, resulting in an increased risk of lung cancer. Animal studies have shown chromium (VI) to cause lung tumors via inhalation exposure.|Chromium is a Standardized Chemical Allergen. The physiologic effect of chromium is by means of Increased Histamine Release, and Cell-mediated Immunity.|Chromium is an element with atomic symbol Cr, atomic number 24, and atomic weight 52.|A trace element that plays a role in glucose metabolism. It has the atomic symbol Cr, atomic number 24, and atomic weight 52. According to the Fourth Annual Report on Carcinogens (NTP85-002,1985), chromium and some of its compounds have been listed as known carcinogens.
