Chromium: biological information
Chromium is an essential trace element and has a role in glucose metabolism. It seems to have an effect in the action of insulin. In anything other than trace amounts, chromium compounds should be regarded as highly toxic.
Levels in humans
- Human abundance by weight: 30 ppb by weight
- Human abundance by atoms: 4 atoms relative to C = 1000000
