Clinical Significance
Detect exposure to thallium.
Thallium is similar to lead and mercury in terms of its toxic properties. Chronic exposure produces alopecia, peripheral neuropathy, seizures, and renal failure. Acute poisoning results in nausea, vomiting, hematemesis, abdominal pain, diarrhea, confusion, coma, and death (in about 10 percent of patients). Thallium is found as a byproduct of lead and zinc smelting and is also used in the manufacture of thermometers, rat poisons, insecticides, semiconductors, luminescent tubes, and dyes.
