Study of effect of petrol vapours and fumes on pulmonary functions of petrol pump workers
Dr. Ishaan Kalavatia and Dr. Veerbhan Singh
Occupational exposures to petrol/diesel vapours have been shown to affect functioning of different systems of the body. The present study was planned to assess the pulmonary functions in petrol pump workers (filling attendants) who are continuously exposed to petrol/diesel vapours during duty hours. 60 petrol pump workers who were categorized into two groups depending on duration of exposure, while thirty healthy non-smoker males from hospital staff served as control group. The pulmonary functions test (PFT) were assessed using computerized spirometer. Following parameter, FVC, TV, FEC, FEV/FC, FEF 25-75%, FEF 75-85%, PEF and MVV were checked. Results showed statistically significant decrease in the values of TV, FVC, FEV, FEF 25-75%, FEF 75- 85%, FEV/FC, PEF and MVV in petrol pump workers who have worked for more than 4 years when compared to control group. The result shows statistically decreased in value of TV, FVC, FEV1, FEF 25-75% and MVV in petrol pump workers who have worked for below 4 years when compared to control group Both the inspiratory and expiratory flow rates were also decreased in the study group. These findings point towards adverse effects of petrol/diesel fumes mainly on lower airways with restrictive pattern of disease. The study concludes that the deleterious effects of air pollution and petrol/diesel vapor inhalation on the lung function of petrol pump workers results in a restrictive type of lung function abnormality. The pattern of respiratory impairment changes to a mixed type as the duration of exposure increases.
