Is Silver Selenide Toxic?

Silver selenide (Ag2Se) is generally considered to be non-toxic, but like any chemical, it can be harmful if ingested or inhaled in large quantities.

Inhalation of silver selenide dust or fumes may cause respiratory irritation and damage to the lungs. Ingestion of large amounts of silver selenide may lead to gastrointestinal symptoms such as nausea, vomiting, and diarrhea. Long-term exposure to silver selenide dust or fumes may also cause skin irritation and discoloration.

It's worth noting that silver selenide is not commonly found in nature, and is usually produced synthetically for use in electronic components, photographic film, and other applications. As with any chemical, proper handling procedures should always be followed to minimize the risk of harm.
