#toxic compound

• Arsenic — The common name given to arsenic trioxide or the element arsenic itself, recognized as an inorganic crystalline mineral compound of extreme toxicity, historically used as a potent poison, but also in infinitesimal doses in medical or metallurgical processes. When used as an adjective, it describes a substance or an acid derived directly from arsenic, capable of forming salts called arsenates.
• Arsenic — Containing arsenic, relating to arsenic, or derived from this metalloid chemical element; describes a substance, mineral composition, or solution in which arsenic is in its higher valence state. In an industrial and geological sense, the term is used to classify certain rocks, sulfurous mineral waters, or synthetic compounds with high structural toxicity, utilized in metallurgy or preservation processes.
• Arsenite — A salt or ester of arsenious acid, structurally obtained through the chemical reaction of arsenic trioxide with a base or an alcohol. Compounds in this class are highly toxic and were historically used on a large scale as insecticides, pesticides, wood preservatives, or herbicides in agriculture, their application being currently strictly regulated due to major environmental and groundwater contamination risks.
• Hydrazoic — Pertaining to hydrazoic acid or derived from it; a term used to describe hydrazoic acid (HN3), an extremely volatile, toxic, and explosive gaseous compound consisting of a group of three nitrogen atoms bonded to a hydrogen atom, as well as its salts known as azides.
