Silicosis: Background, Pathophysiology, Epidemiology
Silicosis is a primary pneumoconiosis involving fibronodular lung disease caused by inhalation of silica dust. Quartz, the most common form of crystalline silica, is abundantly present in granite, slate, and sandstone. [] Although silicosis has been recognized for many centuries, its prevalence increased markedly with the introduction of mechanized mining.
