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:
Inorganic silicon compounds may be acute inhalation irritants. Prolonged
inhalation may cause pulmonary fibrosis known as silicosis.
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.
