Which of the following is true about the feet of pigeons in relation to fenthion?

The statement that fenthion is absorbed through the feet of pigeons is accurate because fenthion, an organophosphate insecticide, acts primarily by being absorbed through the skin. In the case of birds like pigeons, the feet serve as a potential entry point for this chemical when they come into contact with surfaces treated with insecticides. This route of exposure can lead to toxic effects on the birds, particularly affecting their nervous systems since fenthion disrupts the normal functioning of acetylcholinesterase, an enzyme that plays a critical role in neurotransmitter regulation. Therefore, understanding the absorption route through the feet highlights the potential risks for pigeons interacting with surfaces that have been exposed to fenthion.
