Additional Information

Antimony poisoning through acute or chronic exposure is characterized by abdominal pain, dyspnea, nausea, vomiting, dermatitis, and eye irritation. Inhalation is the predominant route of occupational exposure.2 Antimony, employed industrially in pigments, abrasives, and for flameproofing fabrics, is primarily used in the form of inorganic salts. Various organic salts of antimony are available as parasiticides. The metallic form of antimony is used in many alloys.
