SECTION 11. TOXICOLOGICAL INFORMATION
Potential Health Effects:
Eyes: Causes irritating effect
Skin: Irritant to skin and mucous membranes
Ingestion: May cause irritation
Inhalation: May cause irritation
Chronic: Gallium and gallium compounds may cause metallic taste, dermatitis, depression of the bone marrow function. Large doses may cause hemorrhagic nephritis. Tellurium is converted in the body to dimethyl telluride which imparts garlic-like odor to the breath and sweat. Heavy exposure may result in headache, drowsiness, metallic taste, loss of appetite, nausea, tremors, convulsions, and respiratory arrest.
