SECTION 11. TOXICOLOGICAL INFORMATION

Information on toxicological effects

Acute toxicity:

Harmful if inhaled.

Harmful if swallowed.

LD/LC50 values that are relevant for classification: No data

Skin irritation or corrosion: Irritant to skin and mucous membranes.

Eye irritation or corrosion: Irritating effect.

Sensitization: No sensitizing effects known.

Germ cell mutagenicity: No effects known.

Carcinogenicity:

EPA-B2: Probable human carcinogen, sufficient evidence from animal studies; inadequate evidence or

no data from epidemiologic studies.

IARC-2B: Possibly carcinogenic to humans: limited evidence in humans in the absence of sufficient

evidence in experimental animals.

NTP-R: Reasonably anticipated to be a carcinogen: limited evidence from studies in humans orsufficient evidence from studies in experimental animals.

ACGIH A3: Animal carcinogen: Agent is carcinogenic in experimental animals at a relatively high dose,

by route(s) of administration, at site(s), of histologic type(s), or by mechanism(s) not considered

relevant to worker exposure. Available epidemologic studies do not confirm an increased risk of

cancer in exposed humans. Available evidence suggests that the agent is not likely to cause cancer in

humans except under uncommon or unlikely routes or levels of exposure.

Reproductive toxicity: May damage fertility or the unborn child.

Specific target organ system toxicity - repeated exposure: May cause damage to organs through

prolonged or repeated exposure.

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

Aspiration hazard: No effects known.

Subacute to chronic toxicity:

Lead and lead compounds may cause abdominal pain, diarrhea, loss of appetite, metallic taste,

nausea, vomiting, lassitude, insomnia, muscle weakness, joint and muscle pain, irritability, headache

and dizziness. Red blood cells may be damaged resulting in anemia. Gastritis and injury to the

kidneys, liver, male gonads, and central nervous system may also occur.

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.
