Effects of Exposure:
To the best of our knowledge the chemical, physical and toxicological properties of tungsten oxide have not been thoroughly investigated and recorded.
Industrially, tungsten oxide does not constitute an important health hazard. Exposure is related chiefly to the dust arising from the crushing and milling of the two chief ores of tungsten, namely scheelite and wolframite. Large overdoses cause central nervous system disturbances, diarrhea, respiratory failure and death in experimental animals
Inhalation: May cause irritation to the respiratory tract.
Ingestion: Moderately toxic by ingestion.
Skin: May cause abrasive irritation.
Eye: May cause abrasive irritation.
Inhalation: No chronic health effects recorded.
Ingestion: Large overdoses may cause nervous system disturbances, and diarrhea.
Skin: No chronic health effects recorded.
Eye: No chronic health effects recorded.
Routes of Entry: Inhalation, Skin, Eyes, and Ingestion.
Target Organs: May affect the respiratory and central nervous systems.
Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory disorders.
Carcinogenicity: NTP: No IARC: No OSHA: No
