You can use this form to calculate how much niobium your body contains. Enter your weight in either kilograms or pounds and click the "Calculate" button. You must enter a number, not text! 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
Hazards and risks associated with niobium:
Niobium compounds are encountered relatively rarely by most people. Unless known otherwise, in the laboratory, all niobium compounds should be regarded as highly toxic. The metal dust causes eye and skin irritation and is likely to be a fire hazard.
