Thallium is a highly toxic and valuable element for which there are known fast-growing hyperaccumulator plants that have some of the greatest bioaccumulation coefficients (plant/soil concentration quotients) of any non-essential element. As with other elements, many hyperaccumulators discovered to date ...
[1]. Under normal atmospheric conditions, the pure element undergoes reaction with oxygen and moisture to form oxides, thereby limiting its uses [1]. A member of the alkali metal family[9], it has 30 isotopes with mass numbers ranging from 179 to 210 out of which the stable ones are a...
Thallium is a scarce, highly toxic element. There are several investigations that report Tl accumulation in plants of the family Brassicaceae. These plants could pose a risk in areas where Tl is present at higher concentrations than normal soils. The present study reports analyses of two wild ...
Thallium predominantly behaves as a lithophilic element in a wide variety of geologic environments (substituting for K+, Rb+ and Cs+ in the crystal structures of different rock-forming minerals) and very rarely displays chalcophile behavior, only under unique conditions when lithophile behavior is ...

Thallium is a complex and intriguing heavy element, having both chalcophile and lithophile characteristics, as well as demonstrating a larger range of isotopic fractionation than theoretically predicted. Thallium typically occurs in low concentrations in geologic settings, however, certain environments can ...
Thallium is a relatively toxic and valuable element, for which there are fast-growing hyperaccumulators that have the highest bioaccumulation coefficients (plant/soil concentration quotients) of any non-essential element. As with other elements, many Tl-hyperaccumulating plants are in the Brassicaceae ...
