Yttrium can be highly toxic to humans, animals and plants. [10] Water-soluble compounds of yttrium are considered mildly toxic, while its insoluble compounds are non-toxic. [53] In experiments on animals, yttrium and its compounds caused lung and liver damage, though toxicity varies with different yttrium compounds.
An yttrium compound is a chemical compound containing yttrium (element symbol: Y). Among these compounds, yttrium generally has a +3 valence.
Group 3 metals have low availability to the biosphere. Scandium, yttrium, and lutetium have no documented biological role in living organisms. The high radioactivity of lawrencium would make it highly toxic to living cells, causing radiation poisoning.
The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals.
YInMn Blue is chemically stable, does not fade, and is non-toxic. It is more durable than alternative blue pigments such as ultramarine or Prussian blue, retaining its vibrant color in oil and water, and is safer than cobalt blue, which is a suspected carcinogen and may cause cobalt poisoning. [26]
American food and drug manufacturers are officially on deadline to reformulate any products containing Red Dye No. 3. The move follows California's 2023 ban, which prohibits the sale of foods ...
Yttrium-90 is produced by the nuclear decay of strontium-90 which has a half-life of nearly 29 years and is a fission product of uranium used in nuclear reactors. As the strontium-90 decays, chemical high-purity separation is used to isolate the yttrium-90 before precipitation.
Seed oils, including peanut oil and sunflower oil, have been in the news a lot recently. Dietitians explain if seed oils are healthy, and health risks of them.
