11 Toxicological information
Acute toxicity:
LD/LC50 values that are relevant for classification:
Oral: LD50: 6170 mg/kg (rat)
LDLo: 750 mg/kg (rbt)
Primary irritant effect:
on the skin: Irritant to skin and mucous membranes.
on the eye: Irritating effect.
Sensitization:
Sensitization possible through inhalation.
Sensitization possible through skin contact.
Other information (about experimental toxicology):
Tumorigenic effects have been observed on tests with laboratory animals.
Mutagenic effects have been observed on tests with human and/or animal DNA cells.
Subacute to chronic toxicity:
Cobalt is an experimental neoplastigen and tumorigen. It is an experimental carcinogen of the connective tissue and lungs. Cobalt metal and inorganic compounds are classified as an animal carcinogen by the ACGIH. Ingestion may cause burning in the mouth, esophagus, and stomach. Inhalation of dusts and fumes may cause irritation of the respiratory tract and labored breathing and coughing. Sensitization, nausea, flushing of the face and ringing in the ears is also possible. Chronic ingestion may result in pericardial effusion, polycardial effusion, polycythemia, cardiac failure, vomiting, convulsions and thyroid enlargement.
Subacute to chronic toxicity:
The Registry of Toxic Effects of Chemical Substances (RTECS) reports the following effects in laboratory animals:
Behavioral - somnolence (general depressed activity).
Behavioral - ataxia.
Gastrointestinal - hypermotility, diarrhea.
Gastrointestinal - tumors.
Vascular - regional or general arteriolar or venous dilation.
Liver - other changes.
Blood - other changes.
Lungs, Thorax, or Respiration - other changes.
Lungs, Thorax, or Respiration - changes in pulmonary vascular resistance.
Kidney, Ureter, Bladder - changes in tubules (including acute renal failure, acute tubular necrosis).
Tumorigenic - neoplastic by RTECS criteria.
Tumorigenic - tumors at site of application.
Tumorigenic - equivocal tumorigenic agent by RTECS criteria.
Musculoskeletal - tumors.
Additional toxicological information:
To the best of our knowledge the acute and chronic toxicity of this substance is not fully known.
IARC-2B: Possibly carcinogenic to humans: limited evidence in humans in the absence of sufficient evidence 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. |
