概要
Chromium(III) potassium sulfate is a sulfate of chromium and potassium. It can be used for leather tanning. Chromium is a chemical element which has the symbol Cr and atomic number 24. It is found naturally occuring in rocks, animals, plants, and soil, and is usually mined as chromite ore. Chromium is most toxic in its +6 oxidation state (chromium(VI)) due to its greater ability to enter cells and higher redox potential. Trivalent chromium (chromium(III)) however, is biologically necessary for sugar and lipid metabolism in humans. (L17, L514)

Metabolism/Metabolites
Chromium is absorbed from oral, inhalation, or dermal exposure and distributes to nearly all tissues, with the highest concentrations found in kidney and liver. Bone is also a major storage site and may contribute to long-term retention. Hexavalent chromium's similarity to sulfate and chromate allow it to be transported into cells via sulfate transport mechanisms. Inside the cell, hexavalent chromium is reduced first to pentavalent chromium, then to trivalent chromium by many substances including ascorbate, glutathione, and nicotinamide adenine dinucleotide. Chromium is almost entirely excreted with the urine. (A12, L16)
