A soft, silvery-white metal that tarnishes easily. Uses. The use of thallium is limited as it is a toxic element. Thallium sulfate was employed as a rodent killer – it is odourless and tasteless – but use of this poison has been prohibited in …

Abstract Very little is known about the behavior of thallium in an aquatic system. Because of its toxicity and pollution potential, a greater understanding of thallium transport pathways in aquatic systems is needed. This study examined the transport of thallium among four basic aquatic components: water, sand, vegetation, and fish. Concentrations of thallium …

Thallium is released into the biosphere from both natural and anthropogenic sources. It is generally present in the environment at low levels; however, human activity has greatly increased its content. Atmospheric emission and deposition from industrial sources have resulted in increased concentrations of thallium in the vicinity of mineral …

Summary. Exposure to thallium occurs mainly from eating food. Exposure to higher levels of thallium may occur in the workplace. Breathing high levels of thallium may result in …

Thallium concentrations of up to 46 μg g −1 (ash basis) have been detected in high-As, high-S lithotypes in the Pond Creek coal bed in Pike and Martin counties, eastern Kentucky [48]. The high concentrations could be attributable to Tl–As substitution in pyrite, which is supported by the correlation of Tl and As with pyritic sulphur.

The thallium contents and ash yield of the combustible blends (CMA–CMD) can be considered statistically the same with an average Tl concentration of 0.76 μg g −1, which represents 1.16 μg g −1 if it is referred to the ashes. Worthy of note is that the total ash yield of the combustible material has values as high as 65% because of the ...

Thorium as a nuclear fuel. Thorium (Th-232) is not itself fissile and so is not directly usable in a thermal neutron reactor. However, it is 'fertile' and upon absorbing a neutron will transmute to uranium-233 (U-233) a, which is an excellent fissile fuel material b. In this regard it is similar to uranium-238 (which transmutes to plutonium ...
