These effects have not been observed in humans. Chronic exposure to tungsten compounds may result in permanent lung damage.
Swallowing will lead to a strong corrosive effect on mouth and throat and to the danger of perforation of esophagus and stomach.
Inhalation may result in respiratory effects such as inflammation, edema, and chemical pneumonitis. May cause coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.
May cause skin burns or irritation depending on the severity of the exposure.
