pneumconiosis




A restrictive disease of the lungs caused by deposition of various kinds of dust in the lungs, inhaled during years of exposure, often in extractive industries. Silicosis, anthracosis, and asbestosis are the principal forms, although aluminum, iron, tin, and cotton fiber also cause pneumoconiosis. Characteristic X-ray changes are seen in the lungs (see chest X-ray).
