The pulmonary and nonpulmonary effects of cement dust exposure in 52 randomly selected, directly exposed cement workers and 24 maintenance workers were investigated. Compared with the nonindustrially exposed population, both subgroups had significantly (P less than 0.001) lower lung function. The lung function of the exposed subjects was probably influenced by the level of physical activity and the level of dust exposure. The more directly exposed cement packers had significantly (P less than 0.05) lower lung function than the less exposed cement loaders. There was no significant difference in the lung function of the directly exposed groups and the maintenance group, but the physically more active cement loaders showed higher lung function values than the maintenance workers. The lung function of the cement workers also decreased with the duration of employment. Cement dust produced significant (P less than 0.001) workshift depression in the lung function of the subjects. The symptoms presented by the subjects were cough and phlegm production, skin irritation, chest tightness, conjunctivitis, catarrh, stomachache, and boils. The prevalence of stomachache among the subjects becomes significant in the light of a finding by other workers of hepatic granuloma in cement workers. The measured dust level in the cement depot was 30.81 mg/m3.

The pulmonary function and symptoms of 125 workers exposed to carbon black in dry cell battery and tire manufacturing plants were investigated. There was no significant difference in the pulmonary function of the subjects in the two plants. There was good agreement in the symptoms reported in the two different factories: cough with phlegm production, tiredness, chest pain, catarrh, headache, and skin irritation. The symptoms also corroborate those reported in the few studies on the pulmonary effects of carbon black. The suspended particulate levels in the dry cell battery plant ranged from 25 to 34 mg/m3 and the subjects with the highest probable exposure level had the most impaired pulmonary function. The pulmonary function of the exposed subjects was significantly lower than that of a control, nonindustrially exposed population. The drop in the lung function from the expected value per year of age was relatively constant for all the study subgroups but the drop per year of duration of employment was more severe in the earlier years of employment. This study has underscored the need for occupational health regulations in the industries of developing countries.
