Abstract Based on a survey of pneumoconiosis carried out in Japan in 1994, this study compared age, number of years at the job and pulmonary function across various occupations, and examined the characteristics of cases in which pulmonary function was worse than expected from the chest x-ray findings. Ventilatory capacity was lower among workers exposed to silica or asbestos, and one-second forced expiratory volume appeared to be lower among silica-exposed workers. Dissociation between x-ray findings and pulmonary function tests were found in certain types of work environment. In this study, all subjects showed pneumoconiosis in their chest x-ray. A longitudinal survey on pneumoconiosis-free subjects is required to clarify the precise association of lung function tests with chest x-ray.
