Thallium
Thallium oxide is used to produce special glass with a high index of refraction, and also low melting glass that becomes fluid at about 125K. An alloy of mercury containing 8% thallium has a melting point 20°C lower than mercury alone. This can be used in low temperature thermometers and switches. Biological role.
Thallium | Chemical Element, Poisonous Metal, Uses
Thallium is typical of the Group 13 elements in having an s 2 p 1 outer electron configuration. Promoting an electron from an s to a p orbital allows the element to be three or four covalent. With thallium, however, the energy required for s → p promotion is high relative to the Tl–X covalent bond energy that is regained on formation of TlX 3; …

It is excreted mainly through the kidneys and the digestive tract over several weeks, which explains the presence of high levels of the compound in 24-hour urine tests (the most reliable method) in contrast to the low plasma levels after more than 4 days have elapsed postexposure. The lethal dose of thallium is 10 to 15 mg/kg [2,3].

ncbi.nlm.nih.govHow does thallium affect human health?People may be exposed to thallium from coal-burning and smelting processes that produce fine particles of the metal. The tiny particles can be inhaled from the air or consumed in food or drink. The human health effects from exposure to low environmental levels of thallium are unknown.Thallium Factsheet | National Biomonitoring Program | CDC
cdc.govWhat are thallium levels?Typical thallium levels in unexposed individuals are below 1 µg/g creatinine ( Schaller et al. 1980 ). Because of the quantitative renal excretion of creatinine and its rather consistent rate of production, creatinine constitutes an endogenous substance suitable for clearance testing.HEALTH EFFECTS
ncbi.nlm.nih.govIs thallium a hazardous waste hazard?Since thallium is nonvolatiie, inhalation exposure may not be a major concern near hazardous waste sites. However, there is potential for oral exposure. Long-term epidemiological studies by the oral route evaluating low-dose exposure would be useful in characterizing the nature of organ changes produced by thallium.HEALTH EFFECTS
