Assessment of Pulmonary Function Test among Petrol Pump Workers in Bankura District

Abstract

Background and Aim: Health problems posed by the pollutants at the working environment of an individual are linked to the nature and level of exposure to these hazardous chemicals. Petrol pump workers are exposed to high level of different types of air pollution along with petrol and diesel vapors exhibit a number of effects on the respiratory functions. The main objective of the study was to assess the pulmonary functions in petrol pump workers (filling attendants) who are continuously exposed to petrol/diesel vapors during duty hours and compare with the normal healthy individuals. Materials and Methods: This is a cross-sectional study was conducted at seven different petrol pumps of Bankura and 65 petrol pump workers (filling attendants) were included. Each subject’s age, smoking habits, the duration of exposure, health conditions, BMI and BP were recorded. Their PFT were assessed using spirometer and was compared with 65 normal healthy individuals. Results: A significant decrease in the values of Tidal Volume, Vital Capacity, Peak Expiratory Flow Rate, Maximum Voluntary Ventilation, Respiratory Rate and Oxygen saturation in petrol pump workers when compared to control group. Significant increase in BP was observed in case of petrol pump workers and reduction in muscle strength. Conclusion: The present findings demonstrate the adverse effects of petrol and diesel vapors and fumes, hydrocarbons markedly decreased the pulmonary functions.
