Biological information

Biological role

Here are a few notes about the biological role of zirconium.

Zirconium has no biological role. The tolerance of human tissues to it makes the metal suitable for some artificial joints and limbs.

Levels in humans

The following gives the abundances of the elements in humans.

	Human abundance [/ppb by weight]: 50
	Human abundance [/atoms (C = 1000000)]: 3

How much zirconium is in your body?

You can use this form to calculate how much zirconium your body contains (provided your browser supports JavaScript). Just enter your weight in either kilograms or pounds and click the "Calculate" button. You must enter a number, not text! Thanks to Mike Piff (The University of Sheffield) for providing the JavaScript. Elements for which there are no data will always give a value of zero for the weight, no matter what you put in the weight box.

Hazards and Risks

Here are a few notes about the hazards and risks associated with zirconium.

Zirconium compounds are encountered relatively rarely by most people. There is little toxicological data but it seems most compounds are not inherently toxic. The metal dust should be treated as a major fire and explosion hazard.
