?? 11 Toxicological information

?? Acute toxicity:
?? Primary irritant effect:
?? on the skin: Irritant to skin and mucous membranes.
?? on the eye: Irritating effect.
?? Sensitization: Sensitization possible through skin contact.
?? 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.
Iron compounds may cause vomiting, diarrhea, pink urine, black stool,
and liver damage. May cause damage to the kidneys. Irritating to the
respiratory tract, they may cause pulmonary fibrosis if dusts are
inhaled.
?? 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.
