    Sep 10, 2017 Abstract. Thallium (Tl ) is a ubiquitous natural trace metal considered as the most toxic among heavy metals.The ionic ratio of Tl is similar to that of potassium (K ), therefore accounting for the replacement of the latter during enzymatic reactions.The principal organelle damaged after Tl exposure is mitochondria. Studies on the mechanisms of Tl include intrinsic pathways altered and ...

    The toxicity of thallium is mainly due to the fact that the mono-valent thallium ion Tl 1 has many properties which are very similar to the common ions potassium, K 1 and sodium Na 1. Since the size of the thallium ion is very close to that of the potassium ion, certain biochemical mechanisms in the body cannot distinguish between the two ...

    Thallium is a highly toxic metal and is predominantly hosted by sulfides associated with low-temperature hydrothermal mineralization. Weathering and oxidation of sulfides generate acid drainage with a high concentration of thallium, posing a threat to surrounding environments. Thallium may also be incorporated into secondary sulfate minerals, which act as temporary storage for thallium.
