title: The relative importance of smoking compared to occupation in decreased pulmonary function.
abstract: This paper reports a study comparing the forced vital capacity (FVC) and forced expiration volume in one second (FEV1) of 684 workers grouped according to smoking habits and to disability from pneumoconiosis. The study was longitudinal and, although the pulmonary function tests decreased with age, as expected, the fall was greater in smokers without occupational lung disease than in non-smokers with occupational lung disease.
