Abstract :

Background & Objective: Occupational exposures to dust, fumes and gases are associated with increased prevalence of respiratory symptoms and impairment of lung functions. The decline in pulmonary function on exposure to welding fumes in steel industries has been reported in many studies. The aim of this study was to assess the effect of welding on the respiratory health of workers in steel factory and also to determine the contribution of smoking to welder�s lung. Methods: The present study was undertaken on 200 workers working in a steel factory engaged in welding . Out of these 200 workers, 100 were welders (workers especially exposed to welding) and the rest of 100 were taken as controls. The controls were selected from office workers, drivers, electricians and maintenance staff. The lung parameter chosen to assess lung function was PEFR (Peak Expiratory Flow Rate). PEFR was carried out using a portable Medspiror. The data was analysed with the help of computer software SPSS 12.0 for Windows and Epi–Info version 6.1. Results: PEFR was decreased significantly in welders as compared to controls. Smoking caused a further decline in PEFR values in cases in comparison to non–smoker cases. Conclusion: In the present study mean PEFR values showed significant reduction in welders as compared to the control group implying impairment of lung function.
