1. Crystalline silica is also known to cause silicosis, a non-cancerous lung disease.2. The inflammatory effects of crystalline silica are apparently mediated by the Nalp3 inflammasome. 3. In the body, crystalline silica particles do not dissolve over clinically relevant periods. 4. The silicotic nodule represents a specific tissue response to crystalline silica . 5. The crystalline silica content of this dust ranged from 3 % to 7 %. 6. Faujasite silica is another form of crystalline silica . 7. The greatest health risk is the potential to develop silicosis from the long-term exposure to crystalline silica . 8. In after-use HTIW crystalline silica crystals are embedded in a matrix composed of other crystals and glasses. 9. However, magmas containing less than 58 % SiO 2 are thought to be unlikely to contain crystalline silica . 10. NIOSH notified company representatives of these findings and provided reports with recommendations to control exposure to crystalline silica .
