  •  10 Toxicological information
      •  
    • Acute toxicity:

      • LD/Lc50 values that are relevant for classification: 
      Oral: LD50: >15000 mg/kg (mus)
    • Primary irritant effect:
    • on the skin: Irritant to skin and mucous membranes.
    • on the eye: Irritating effect.
    • Sensitization: No sensitizing 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-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.
    • Additional toxicological information:

      • To the best of our knowledge the acute and chronic toxicity of this substance is not fully known.
      EPA-B1: Probable human carcinogen, limited evidence of carcinogenicity from epidemiologic studies.
      IARC-1: Carcinogenic to humans: sufficient evidence of carcinogenicity.
      NTP-2: Reasonably anticipated to be a carcinogen: limited evidence from studies in humans or sufficient evidence from studies in experimental animals.
      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.
