Fire HazardsExcerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]:
Health HazardsNone recorded. (USCG, 1999)
Hazards Summary
Ferrocyanide complexes are stable and practically nontoxic because of the strong bonding between iron and cyanide. Cyanide ions may be formed slowly when the chemical is irradiated with UV light. [Ullmann] Solutions may produce hydrogen cyanide on prolonged exposure to sunlight; [Merck Index] Aqueous solutions form hydrogen cyanide when exposed to light; May cause irritation; [MSDSonline]
FDA Requirements
Yellow prussiate of soda (sodium ferrocyanide decahydrate ...) may be safely used as an anticaking agent in salt for animal consumption at a level not to exceed 13 ppm. The additive contains a minimum of 99.0% by weight of sodium ferrocyanide decahydrate. /Sodium ferrocyanide decahydrate/
化学と産業
薬理情報
Metabolism/Metabolites
Cyanide is rapidly alsorbed through oral, inhalation, and dermal routes and distributed throughout the body. Cyanide is mainly metabolized into thiocyanate by either rhodanese or 3-mercaptopyruvate sulfur transferase. Cyanide metabolites are excreted in the urine. (L96)
Absorption, Distribution and ExcretionRAPIDLY EXCRETED IN URINE, APPARENTLY WITHOUT METABOLIC ALTERATION.
