through prolonged or repeated exposure. Route of exposure: Oral, Inhalative.

Specific target organ system toxicity - single exposure: No effects known.

Aspiration hazard: No effects known.

Subacute to chronic toxicity:

Acute and chronic exposure to inorganic mercury can cause salivation with metallic taste, pain on

chewing, gingevitis, colitis, stomatitis, kidney damage, and central nervous system damage. The latter

can cause tremors, convulsive or shaking movements and psychic disturbances such as memory loss,

insomnia, loss of confidence, irritability and depression.

Excessive exposure may result in death.

Tellurium is converted in the body to dimethyl telluride which imparts a 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.

Subacute to chronic toxicity: No effects known.

Additional toxicological information:

To the best of our knowledge the acute and chronic toxicity of this substance is not fully known.
