Title: Effect of exposure to cement dust on lung function of workers at Atbara Cement Factory
Author: Saeed, Amal
Abstract: Background: Exposure to Portland cement dust has long been associated with the prevalence of respiratory symptoms and varying degree of reduction in lung function. It also causes dermatitis, lung and laryngeal cancer and gastrointestinal tumors. Objectives: This study assessed the effect of exposure to cement dust on lung function in factory workers at Atbara cement factory by measuring Forced Vital Capacity (FVC), Forced Expiratory Volume in the first second (FEV1), FEV1/FVC ratio and Peak Expiratory Flow Rate (PEFR). Methods: Forty workers employed for at least 3 years and forty controls (non exposed) were selected. The two groups were matched in terms of age, height and sex. The age of the subjects ranged between 20-50 years. Both groups were non smokers, had no cardiopulmonary diseases or symptoms during the time of study. Spirometer and Wrights Peak Flow Meter were used for measuring lung functions. Results: Statistically, significant reduction in FVC, FEV1 and PEFR were found in exposed workers when compared to control. The FEV1/FVC ratio, although was less in exposed workers, the difference was found to be insignificant. Lung function indices were found to be reduced with increasing duration of exposure to cement dust. Conclusion: Reduction in FVC, FEV1, PEFR implies that exposure to Portland cement dust may result in restrictive and obstructive pulmonary diseases. The insignificant difference in FEV1/FVC ratio may indicate that there is less element of obstructive pulmonary disease. Further studies with large sample sizes are needed to evaluate the effect of exposure to Portland cement dust on Sudanese workers.
