Thallium
Heavy metalA highly toxic metal found in some ores, electronics, and legacy rodenticides.
Where it comes from in service
Rare; some electronics, smelting, and contaminated environments.
How it harms the body
Thallium disrupts potassium-dependent processes and is toxic to nerves and the kidneys.
How long it stays in you
Distributes widely; clears over weeks but can injure nerves.
Where it goes — tap an organ to go deeper
ATSDR links thallium to peripheral neuropathy and other effects.
Nerve injury can progress; a clinician should evaluate suspected exposure.
