Abstract

After prolonged occupational exposure to amorphous silica dust - a product of vaporized crystalline silica (quartz) - 11 out of 40 workers showed reticular and/or nodular abnormalities in roentgenograms of the chest. From this group the authors present 3 illustrative cases. These had widespread pulmonary disease with granulomatous nodules and fibrosis (documented histologically in 2 cases), but there was no demonstrable restrictive impairment of pulmonary function. They discuss the possible importance of this previously underestimated toxicity, especially in an industrial setting.
