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]
Zinc phosphide is a common ingredient in rat poison or rodenticide. Zinc phosphide is a combination of phosphorus and zinc. If ingested, the acid in a dog's stomach turns the compound into phosphine, which is a toxic gas. The phosphine gas crosses into the dog's cells and causes the cell to die.
Zinc phosphide is typically added to rodent baits in amount of around 0.75-2%. Such baits have a strong, pungent garlic-like odor characteristic of phosphine liberated by hydrolysis. The odor attracts rodents, but has a repulsive effect on other animals; However, birds, notably wild turkeys, are not sensitive to the smell. The baits have to ...
All parts of the plant are considered poisonous to animals, though — with the seeds being the most toxic. Sago palm contains cycasin, a toxic agent that can cause liver failure in dogs. Symptoms ...
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.
While plants make good additions to most homes, some can carry toxic substances that are unsafe for pets. Avoid these 12 if you have furry pals at home.
