Thallium toxicity: A growing concern

Thallium toxicity in humans.

Thallium is a naturally occurring trace element, widely distributed in the earth's crust, but at very low concentrations. It does not have a known biological use and does not appear to be an essential element for life. It has been considered one of the most toxic heavy metals.Occasionally, there are reports on thallium poisoning as results of suicide or murder attempt or accident. The main thre...

Grand Rounds Guy 's Hospital Thallium poisoning

BMJ 1993;306:1527-9 Thallium is a heavy metal whose salts are used in some rodent poisons and in the manufacture of optical lenses, semiconductors, scintillation counters, low temperature thermometers and switching devices, green coloured fireworks, and imitation jeweliery, and as chemical catalysts. In clinical practice thallium isotopes are used in cardiac scanning,12 but the use of thallium ...

Frenching of Tobacco Distinguished from Thallium Toxicity by Spectrographic

Several theories as to the cause of tobacco frenching have been proposed, but each in its turn has been found to be erroneous. Kecently, it has been postulated that frenching is probably a symptom of thallium toxicity. Since the demonstration of the presence of thallium in frenched tobacco tissue in toxic amounts or its absence is essential to an evaluation of the thalhum-toxicity theory, and t...

Arsenic, Antimony, Chromium, and Thallium Speciation in Water and Sediment Samples with the LC-ICP-MS Technique

Chemical speciation is a very important subject in the environmental protection, toxicology, and chemical analytics due to the fact that toxicity, availability, and reactivity of trace elements depend on the chemical forms in which these elements occur. Research on low analyte levels, particularly in complex matrix samples, requires more and more advanced and sophisticated analytical methods an...
