What is its Origin?

OSHA has special workplace requirements for working with Cr (VI).

Chromium is a chemical element in the periodic table (symbol Cr). Chromium metal is extremely resistant to corrosion and oxidation, which is why it is used in stainless steel and chrome plating. Chromium (VI), or Hexavalent Chromium, is a form of chromium that is commonly combined with other elements to form compounds. The Roman numeral number indicates the number of valence electrons, which determines the types of compounds or chemical reactions a substance can participate in. Chromium(VI) is rapidly transformed by organic matter into chromium(III). Therefore, significant quantities of chromium(VI) are not a natural occurrence but rather almost always the result of human actions.
