Summary
A group of 35 carbon-black workers were examined twice within a period of 6 years. Gravimetric determination of total and respirable particles and particle size analysis of thermal precipitator samples were used to assess the exposure level. The forced vital capacity (FVC) and forced expiratory volume in the first second (FEV1) were measured and X-rays were taken of each subject. Within the period of 6 years both FVC and FEV1 values deteriorated significantly, the average annual decline of FVC being four and of FEV1 more than three times higher than those expected for the normal male population. Radiological lung changes found in 17.1% of the workers progressed during the observation period.
