Fast Globalization trends, rapid industrial growth, and poor environmental conditions at work places have created a lot of health- related issues and complications. The main aim of this study is to study the dynamic lung function tests in occupationally exposed petrol pump workers of western Maharashtra. The study was conducted on 70 male petrol pump workers &70 normal controls to find out the effect of occupational exposure to petroleum product on dynamic lung function tests. PFT were studied by using computerized spirometer. Parameters of PFT are FEV1, FVC, FEV1/FVC ratio, PEFR, FEF 25%, FEF 50 %, FEF 75 % FEF 25-75, MVV was recorded and compared with normal predicted value. Analysis was done using unpaired t-test. There was a statistically significant decrease in FEV1, FVC, PEFR, FEV1/FVC ratio, PEFR, FEF 25%, FEF 50 %, FEF 75 % and FEF 25-75 in petrol pump workers as compared to control. MVV was decreased in petrol pump workers but it was not found to be statistically significant. It was concluded that dynamic lung function tests of petrol pump workers were significantly decreased. Our findings suggest that the adverse effects of petroleum vapors on lung function with mixed pattern of lung diseases.
