A type of pneumoconiosis. Also called asbestosis. Asbestos is a general term for fibrous silicate minerals, and is widely used as an industrial raw material. In recent years, the use of asbestos has rapidly increased in shipbuilding, construction, automobile brake linings, and other fields, and the opportunities for occupational and non-occupational exposure to asbestos have increased. Asbestosis is a disease that begins with respiratory bronchiolitis and alveolitis, leading to diffuse pulmonary fibrosis, and is accompanied by thickening of the parietal pleura (called pleural plaque) and calcification.
