Carcinogen as defined by OSHA.

ACGIH A2: Suspected human carcinogen: Agent is carcinogenic in experimental animals at dose

levels, by route(s) of administration, at site(s), of histologic type(s), or by mechanism(s) considered

relevant to worker exposure.

Available epidemiologic studies are conflicting or insufficient to confirm an increased risk of cancer in

exposed humans.

Reproductive toxicity:

No effects known.

Specific target organ system toxicity - repeated exposure:

No effects known.

Specific target organ system toxicity - single exposure:

No effects known.

Aspiration hazard: No effects known.Subacute to chronic toxicity:

Cadmium and cadmium compounds are highly toxic and experimental carcinogens. Exposure affects

the respiratory tract, kidneys, and liver. Ingestion may cause nausea, salivation, vomiting and diarrhea.

Ingestion or inhalation of cadmium/cadmium compounds may be fatal.

Tellurium is converted in the body to dimethyl telluride which imparts a garlic-lik

e odor to the breath and sweat. Heavy exposure may result in headache,

drowsiness, metallic taste, loss of appetite, nausea, tremors, convulsions, and respiratory arrest.

Cadmium compounds are highly toxic and experimental carcinogens. Exposure affects the respiratory

tract, kidneys, and liver.

Ingestion may cause nausea, salivation, vomiting and diarrhea. Ingestion or inhalation of cadmium

compounds may be fatal.

Subacute to chronic toxicity:

The Registry of Toxic Effects of Chemical Substances (RTECS) reports the following effects in

laboratory animals:

Behavioral - tremor.

Behavioral - changes in motor activity (specific assay).

Nutritional and Gross Metabolic - weight loss or decreased weight gain.

Additional toxicological information:

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