Sodium monofluoroacetate

Sodium fluoroacetate is a chemical compound that is a poison for many organisms. Pesticides used kill rodents sometimes contain Sodium monofluoroacetate. Sometimes the chemical substance is used as a marker for cancer cells in Positron emission tomography. TO act as a marker, only very small quantities of a substance are needed. For this reason, the toxicity of Sodium fluoroacetate is not a problem.

Dichapetalum cymosum

Fluoroacetate occurs naturally in at least 40 plants in Australia, Brazil, and Africa. It was first identified in the poison leaf (gifblaar) Dichapetalum cymosum by Marais in 1944.[1][2] As early as 1904, colonists in Sierra Leone used extracts of Chailletia toxicaria which also contains fluoroacetic acid or its salts to poison rats.[3][4][5] Several native Australian plant genera contain the toxin, including: Gastrolobium, Gompholobium, Oxylobium, Nemcia and Acacia.
