SODIUM TUNGSTATE

Health hazards

Information OSHA Effects of Overexposure Skin Contact: Contact may cause skin irritation. Eye Contact: Information Eye Contact: Contact may be irritating to the eyes. Ingestion: Ingestion of soluble tungsten compounds can cause nervous prostration, diarrhea. Inhalation: Inhalation may irritate the nose, throat and upper respiratory tract.

Potential chronic health

of Overexposure Animal studies suggest that soluble tungsten compounds may cause adverse gastrointestinal and central nervous sytem effects. These effects have not been observed in humans.
