What is an interesting fact about yttrium?
Yttrium can be found in most of the rare earth minerals, but has never been discovered in the Earth’s crust as a freestanding element. Lunar rocks gathered during the Apollo moon missions contain yttrium. The human body also contains yttrium in tiny amounts, usually concentrated in the liver, kidneys, and bones.
Are lanthanides safe?
In recent years, however, some scientists have questioned lanthanides’ safety. In matters concerning health care, for example, some MRI patients have attributed a litany of side effects, including long-term kidney damage, to their exposure to the lanthanide gadolinium, a commonly used MRI contrast agent.
