aluminum phosphide

A pesticide used to protect stored grains from insects and rodents. After exposure to water it is converted to hydrogen phosphide, a poison that inhibits cellular oxidative metabolism, esp. in metabolically active organs. It may be toxic or deadly to humans if ingested or inhaled. Its chemical formula is AlP.


There is no specific antidote. Cardiopulmonary support is given to intoxicated patients.

hydrogen phosphide

A poison that is released when phosphide pesticides react with water. It inhibits oxidative metabolism in cells and may be deadly if eaten or inhaled. Chemical formula is PH3. Synonym: phosphine

zinc phosphide

A toxic pesticide that releases hydrogen phosphide after exposure to water. Its chemical formula is Zn3P2.
