Medications altered by grapefruit include highly prescribed cholesterol-lowering statins, some key heart drugs, and certain anti-psychotic and pain medicines. Thatâs because grapefruit contains a chemical that interferes with an enzyme that controls how drugs are absorbed through the intestines, resulting in a potentially toxic dose of medication.
Yttrium is mostly dangerous in the working environment, due to the fact that damps and gasses can be inhaled with air. This can cause lung embolisms, especially during long-term exposure. Yttrium can also cause cancer with humans, as it enlarges the chances of lung cancer when it is inhaled.
The story of yttriumâs discovery begins in 1787, when Carl Arrhenius found a coal-like mineral in a feldspar/quartz mine near Ytterby, Sweden. The mine had been developed in the early 18th century as a result of the mineral requirements of the local pottery industry.
