Toxicity: A member element of group IVa in the Periodic Table with both metallic and non-metallic properties. Tellurium compounds of biological interest include the elemental form, as well as compounds with valences of 12 (telluride), 14 (tellurite), and 16 (tellurate). Commercial applications of tellurium include its use as a coloring agent and as an alloy with other metals. Industrial hazards generally involve the volatile forms including tellurium dioxide and hydrogen telluride rather than the less toxic elemental form. Exposure to potassium tellurite may also occur; this compound is known to cause hemolysis of erythrocytes, probably via its reduction product, telluride. Other non-nervous system effects of exposure to tellurium compounds include weight loss, blue/ black discoloration of skin, and a characteristic garlic breath odor. Animal models have clearly implicated tellurium in induction of specific neuropathological findings. These include its action as a teratogen in the induction of communicating hydrocephalus (treated rats give rise to affected offspring), lipofuscinosis, and peripheral neuropathy.

Use

Small amounts of tellurium are added to stainless steel and copper to improve their machinability. It enhances the strength and hardness of lead and protects lead from the corrosive action of sulfuric acid. Tellurium also is a strong chilling agent in iron castings. It controls the chill and imparts a tough abrasion resistance to the surface.
