Chromium. Chromium is an essential mineral that the body needs in trace amounts. It is naturally present in a wide variety of foods, though only in small amounts, and is also available as a supplement. Chromium enhances the action of the hormone insulin. [1) It is also involved in the breakdown and absorption of carbohydrate, proteins, and fats.

Controlling hexavalent chromium levels • Product substitution. Use a less toxic substitute in place of Cr(VI). For example, trivalent chromium is less toxic than Cr(VI). There are a variety of alternatives available that provide similar characteristics to chrome electroplating. • Reduce mist generation. Chemical surfactants

Adverse health effects associated with Cr (VI) exposure include occupational asthma, eye irritation and damage, perforated eardrums, respiratory irritation, kidney damage, liver damage, pulmonary congestion and edema, upper abdominal pain, nose irritation and damage, respiratory cancer, skin irritation, and erosion and discoloration of the teeth.

Chromium. Chromium is hard, brittle semi-grey metal. As a compound, it has varied and robust colors. Chromium ion forms many coordination compounds. In active and passive forms, the latter gives rise to its corrosion resistance due to a thin surface oxide layer that passivates the metal when treated with oxidizing agents.
