Is yttrium toxic to humans?

Is yttrium toxic to humans?

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.

What happens if you eat yttrium?

It can cause scarring of the lungs, anemia and changes in blood cell distribution, due to inhalation of their dusts. If swallowed do NOT induce vomiting.

Do humans use ytterbium?

Ytterbium has no biological role, but it has been noted that its salts stimulate metabolism. Ytterbium is a skin and eye irritant and it is also a suspected teratogen.

What can yttrium do?

A soft, silvery metal. Yttrium is often used as an additive in alloys. It increases the strength of aluminium and magnesium alloys. It is also used in the making of microwave filters for radar and has been used as a catalyst in ethene polymerisation.

How much does yttrium cost?

Yttrium is currently worth $3,400 per pound, europium costs $20,000 per 100 grams and terbium sells for $1,800 per 100 grams. Dysprosium, the cheapest of the rare-earth elements discovered, only costs $450 per 100 grams.

How do you dispose of yttrium?

Yttrium Oxide Dispose of contents and container to an approved waste disposal plant.

Where is yttrium found?

It is mined in China and Malaysia. Yttrium also occurs in the other ‘rare earth’ minerals, monazite and bastnaesite. Yttrium metal is produced by reducing yttrium fluoride with calcium metal.

What is the 70th element?

Ytterbium is a chemical element with symbol Yb and atomic number 70.

Is yttrium an alkali metal?

Yttrium is a chemical element with the symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a “rare-earth element”….

How is yttrium used?

Yttrium is often used as an additive in alloys. It increases the strength of aluminium and magnesium alloys. It is also used in the making of microwave filters for radar and has been used as a catalyst in ethene polymerisation. Yttrium-aluminium garnet (YAG) is used in lasers that can cut through metals.

How is yttrium used in phones?

Yttrium is widely used to produce phosphors that are used in cell phones and larger display screens as well as general lighting.

Where is yttrium found in the human body?

Yttrium has no known biological role, though it is found in most, if not all, organisms and tends to concentrate in the liver, kidney, spleen, lungs, and bones of humans. Normally, as little as 0.5 milligrams is found in the entire human body; human breast milk contains 4 ppm.

What is yttrium oxide?

Carl Gustaf Mosander in 1843, investigated this metal in depth and found three more oxides, white yttrium oxide, yellow terbium oxide and rose-colored erbium oxide [2]. Yttrium is rare earth mineral found in uranium ores.

What are the long term effects of yttrium exposure?

Continuous and long-term exposure to yttrium may cause lung diseases. As an occupational hazard, workers may experience mild eye, skin and upper respiratory tract irritation. The most important isotopes of yttrium are 91 Y and 90 Y having half-lives of 58.51 days and 64 hours.

Is yttrium a metal or nonmetal?

Yttrium is a transition metal. Transition metals are those elements in Groups 3 through 12 of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other.
