The work environment seriously influences the organism of exposed human. The occupational hazards, such as dust, unfavourable microclimatic condition, and excessive noise and in sufficient light are most important. The occupation related lung diseases are most likely due to the deposition of dust in the lungs and are influenced by the short (types) of dusts, the period of exposure, the concentration and size of airborne dust in the breathing zone. Present study was undertaken to study the effect of flour dust on respiratory functions of exposed workers. Method: We evaluated 50 male subjects in the age group of 18-50 years consisting of 50 industrial workers from flour mills in different areas of Bhavnagar city. Computerized spirometric parameters of flour mill workers (FMW) were done by computerized software of pulmonary function test named “SPIROEXCEL”and compared with their predicted values. The various data were collected; compiled, statistically analyzed and valid Conclusion were drawn. Result: The present study results showed the mean values of FVC, FEV1, Mid expiratory flow rate, FEF25%, FEF50%, FEF75%, SVC, PEFR, and MVV were decreased in flour mill worker as compared with their predicted value, which were statistically significant. Conclusion: Flour dust causes chronic bronchial irritation which is responsible for causing restrictive type and restrictive plus obstructive mix type of pulmonary function impairment in flour mill workers. |
