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.
