It is highly toxic to humans and reacts violently with water. It is produced by the body when tellurium or one of its compounds are ingested. It is noticeable by its [[garlic]]-like smell. Anyone who has been working with or exposed to tellurium and exhibits this garlic-like smell on the breath, [[sweat]] or in the [[urine]] should remove themselves from the area. Tellurium is known to be [[toxic]].

The toxicity of DMTe is unclear. It is produced by the body when [[tellurium]] or one of its compounds are ingested. It is noticeable by the garlic smelling breath it gives those exposed, similar to the effect of [[Dimethyl sulfoxide|DMSO]]. Tellurium is known to be [[toxic]].<ref>{{ cite journal |author1=Chasteen, T.
