Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula P H 3, classed as a pnictogen hydride.Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane (P 2 H 4).
Phosphine, a toxic, colourless gas, is the most stable phosphorus hydride. It is insoluble in water but soluble in organic liquids (as well as carbon disulfide and trichloroacetic acid). Phosphine is a reducing agent. [3] Arsine, stibine, and bismuthine are highly toxic, thermally unstable, and colourless gases.
Zinc phosphide is highly toxic, especially when ingested or inhaled. The reason for its toxicity is the release of phosphorus compounds, usually phosphine , when it reacts with water and acids. Phosphine is very toxic and, with trace amounts of P 2 H 4 , pyrophoric .
Phosphine (PH 3) and its organic derivatives (PR 3) are structural analogues of ammonia (NH 3), but the bond angles at phosphorus are closer to 90° for phosphine and its organic derivatives. Phosphine is an ill-smelling, toxic gas. Phosphorus has an oxidation number of −3 in phosphine. Phosphine is produced by hydrolysis of calcium phosphide ...
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
Fruits, vegetables, seeds and beans are all essential parts of a well-balanced and healthy diet, but if these health gems are not consumed properly, they could be poisonous and detrimental to our ...
Aluminium phosphide poisoning is poisoning that occurs as a result of excessive exposure to aluminium phosphide (AlP), which is readily available as a fumigant for stored cereal grains and sold under various brand names such as QuickPhos, Salphos and Celphos. Aluminium phosphide is highly toxic, especially when consumed from a freshly opened ...
According to the ASPCA’s toxic plant database, symptoms of mistletoe poisoning include vomiting, diarrhea, low blood pressure (rarely), difficulty breathing, and low heart rate. However, she ...
