Respiratory effects of portland cement dust
An epidemiologic study of the respiratory effects of Portland cement dust was conducted. The cohort consisted of 2,736 cement workers at 16 facilities in the United States. The comparisons consisted of 2,213 individuals in activities not involving dust exposure. Spirometry testing was performed. Respiratory-symptom questionnaires were administered. Chest x-rays were taken and examined. Personal sampling for total and respirable dust, quartz, and oxides of sulfur and nitrogen was performed. Cement workers had a significantly elevated adjusted-odds ratio for dyspnea, rounded and irregular small x-ray opacities, and pleural abnormalities. None of the ventilatory-function variables were significantly different between cement workers and the comparisons. The authors conclude that cement dust exerts little adverse effect on respiratory symptoms and ventilatory function. To determine whether the increase in x-ray abnormalities represents pneumoconiosis or another pathological process would require histological study. There is insufficient evidence to suggest a change in the exposure limit for cement dust.
