Phosphine is a highly toxic respiratory poison, and is immediately dangerous to life or health at 50 ppm. Phosphine has a trigonal pyramidal structure. Phosphines are compounds that include PH 3 and the organophosphines, which are derived from PH 3 by substituting one or more hydrogen atoms with organic groups. [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.
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.
Megan Liu, lead study author and science and policy manager at Toxic-Free Future, tells Yahoo Life that this was a “minor point” in the study. “We feel bad that this happened,” she adds.
Phosphines or phosphanes are phosphorus compounds derived from phosphine and have the general structure R 3 P. For the nitrogen analogues, please see Category:Inorganic amines . Wikimedia Commons has media related to Phosphines .
A blood agent is a toxic chemical agent that affects the body by being absorbed into the blood. [1] Blood agents are fast-acting, potentially lethal poisons that typically manifest at room temperature as volatile colorless gases with a faint odor. [1] They are either cyanide- or arsenic-based. [1]
Immediately rinse skin with rubbing alcohol, poison plant wash, or degreasing soap (such as dishwashing soap) or detergent, and lots of water. Rinse frequently so that wash solutions do not dry on ...
