11 Toxicological information
Acute toxicity:
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:
Selenium may cause amyotrophic lateral sclerosis, bronchial irritation,
gastrointestinal distress, vasopharyngeal irritation, garlic odor on
breath and sweat, metallic taste, pallor, irritability, excessive
fatigue, loss of fingernails and hair, pulmonary edema, anemia and weight
loss.
Lead and lead compounds may cause abdominal pain, diarrhea, loss of
appetite, metallic taste, nausea, vomiting, lassitude, insomnia, muscle
weakness, joint and muscle pain, irritability, headache and dizziness.
Red blood cells may be damaged resulting in anemia. Gastritis and injury
to the kidneys, liver, male gonads, and central nervous system may also
occur.
Additional toxicological information:
May cause harm to the unborn child.
Possible risk of impaired fertility.
To the best of our knowledge the acute and chronic toxicity of this
substance is not fully known.
EPA-B2: Probable human carcinogen, sufficient evidence from animal
studies; inadequate evidence or no data from epidemiologic studies.
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.
