National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Respiratory Effects of Portland Cement Dust.

PB86226958

Publication Date	1985
Personal Author	Abrons, H. L.; Sanderson, W. T.; Petersen, M. R.
Page Count	61
Abstract	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 (14808607), 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.
