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.

Respiratory symptoms and spirometric pulmonary function data [i.e., first-second forced expiratory volume (FEV1.0) and forced vital capacity (FVC)] for 128 (30%) males who were exposed to alkyl benzene sulphonate in a detergent factory and for 56 (76%) unexposed workers in the same factory are reported herein. Exposed subjects had been employed for 1 month to 15 yr, and they generally complained of cough and mucus secretions, nasal catarrh, chest pain, and breathlessness. Unexposed workers had been employed for 1 month to 13 yr and had a significantly lower (P less than .001) frequency of symptoms, as well as significantly higher (.01 greater than P greater than .001) FEV1.0 and FVC than the exposed workers. The reduction in pulmonary function of exposed subjects from the predicted was significantly higher (.01 greater than P greater than .001) than that experienced by the unexposed subjects. There was a significant 8-hr workshift depression in lung function. There was radiological evidence of pulmonary fibrosis, but lack of pre-employment chest radiographs renders this inconclusive. Respiratory symptoms in exposed subjects decreased with duration of employment, which probably indicates the exodus from the work force of those who could not tolerate the nonsoapy detergent.
