Looking into Metal of Row 6 Column 13: Thallium

Dr Nethravathi B

  •  THALLIUM was first discovered by WILLIAM CROOKES, in March 1861.
  • Thallium name is derived from Bright green line in its emission spectrum, Greek word ‘THALLOS’, meaning green twig.
  • This naturally occurring trace element, soft, malleable, is odourless, tasteless, water soluble, hence more accidental and criminal intoxication are reported, mainly a cumulative poison. 3 ways of absorption – Absorption through Skin, Respiratory inhalation, Absorption through Gastrointestinal tract.
  • The most toxic heavy metal, readily absorbed poison by skin is nicknamed as ‘POISONER’S POISON’ & ‘INHERITANCE POWDER’ (also Arsenic – more gastrointestinal symptoms with peripheral neuropathies, Thallium – alopecia with peripheral neuropathies)
  • Mostly used as rodenticide, pesticide also used in treatment of syphilis, gonorrhoea, gout, dysentery.

PATHOPHYSIOLOGY – Thallium is structurally similar to Potassium, hence enter body through potassium uptake pathways. Thallium affects cells and mitochondria, by causing oxidative stress and producing ROS, triggering apoptosis, impeding the electron transport chain, lowering ATP synthesis, changing membrane permeability, and harming DNA and proteins.
