PULMONARY FUNCTION TESTS IN PETROL FILLING WORKERS IN MYSORE CITY
AbstractBackground: With urbanisation and rapidly increasing number of automobiles, there is increasing establishment of petrol filling stations. Occupational exposure to petroleum vapours have been shown to affect functioning of different systems of the body. The present study was taken up to assess the Pulmonary Function Tests (PFT) in petrol filling workers in Mysore city. Methods: Twenty-eight non-smoker males in the age group of 18â€“30 year working in petrol filling station as petrol filling workers for more than 2 years formed the study group. Age and sex matched individuals not exposed to fuel vapour served the control group. Pulmonary function parameters FEV1, FVC, PEFR, MVV, and FEV1/FVC were assessed using computerised Spirometer during their working hours and were statistically analysed. Results: There was a statistically significant decrease in FEV1 and FVC in study group compared to control group with normal FEV1%. The decrease in PEFR, and MVV was statistically non-significant. Conclusion: The above findings point towards adverse effects of petroleum vapours on lung function, mainly on lower airways with restrictive pattern of disease.
