Abstract

After prolonged occupational exposure to amorphous silica dust-a product of vaporized crystalline silica (quartz)-eleven out of forty workers showed reticular and/or nodular abnormalities in roentgenograms of the chest. From this group, we present three illustrative cases. These had widespread pulmonary disease with granulomatous nodules and fibrosis (documelltd histologically in two cases), but there was 110 demonstrable restrictive impairment of pulmollary function. We discuss the possible imponance of this previollsly underestimated toxicity, especially in all industrial setting.
