Assessment of Lung Function among Wool Textile Workers in Al-Nassiriya Industry


Background: Chronic exposure to wool dust is related to specific respiratory symptoms, due to high ambient dust concentration and the observed adverse effects on lung function.Objective: to assess the pulmonary function of wool textile workers.Methodology: A cross-section study which included 689 workers was studied at departments of Al-Nassiriya wool industry south of Iraq. Spirometric assessment was done by measuring forced expiratory volume during first second, forced vital capacity and forced expiratory volume during first second / forced vital capacity ratio for each workers by simple spirometry.Results: pulmonary function test was abnormal for 16.6% of the sample, and 74.5% of workers with abnormal lung function were above 40 years of age.Conclusion: The percentage of workers with abnormal lung functions is significantly related to the duration of employment.Abbreviations: FVC: Forced expiratory Volume, FEV1: Forced expiratory Volume in 1 second, COPD: Chronic Obstructive Pulmonary Disease. Key words: pulmonary function test, spirometry
