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 amyotropic 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,
