Chromate conversion coating
The formulations typically contain hexavalent chromium compounds, such as chromates and dichromates. Chemistry
The chromate coating process starts with a redox reaction between the hexavalent chromium and the metal.

Cornforth reagent
In its chemical structure and functions it is closely related to other compounds made from hexavalent chromium oxide, such as pyridinium chlorochromate Because it contains hexavalent chromium, it is a suspected carcinogen, and as a strong oxidant, pyridinium dichromate promotes fires, releasing carbon

Chromium cycle
and river transport
Chromium has two common oxidation states relevant for environmental conditions: trivalent chromium, Cr(III) (reduced form), and hexavalent Hexavalent chromium is reduced to trivalent chromium in oxygen minimum zones or at the surface of the ocean by divalent iron and organic ligands.

Bismuth phosphate process
Plutonium would be carried by the bismuth phosphate in the tetravalent state but not in the hexavalent state. Lanthanum salts and hydrogen fluoride were added again and lanthanum fluoride was precipitated, while hexavalent plutonium was left in solution.

Hexavalent chromium
Hexavalent chromium, also called chromium(VI), is hemotoxic, genotoxic, and carcinogenic. The median lethal dose of hexavalent chromium is 50–150 mg/kg.
