Thallium poisoning is poisoning due to thallium and its compounds which are often highly toxic.
Part of the reason for thallium's high toxicity is that, when present in aqueous solution as the univalent thallium(I) ion (Tl+), it exhibits some similarities with essential alkali metal cations, particularly potassium (due to similar ionic radii). It can thus enter the body via potassium uptake pathways.
Among the distinctive effects of thallium poisoning are peripheral nerve damage (victims may experience a sensation of “walking on hot coals”) and hair loss (which led to its initial use as a depilatory, before its toxicity was properly appreciated). However, hair-loss generally only occurs with low doses; with high doses, the thallium kills before this can take effect. Thallium was once an effective murder weapon, before its effects became understood and an antidote (Prussian blue) discovered. It has been called the "poisoner's poison" since it is colorless, odorless, and tasteless; its slow-acting, painful and wide-ranging symptoms are often suggestive of a host of other illnesses and conditions. People who ingested large amounts of thallium over a short time have reported vomiting, diarrhea, temporary hair loss, and effects on the nervous system, lungs, heart, liver, and kidneys. It has caused death.
