Background: Rapid rise in petrol pump filling station is seen in the last decade, and air pollution had increased drastically. Air pollutants and components in petrol may have delirious effect on respiratory health. Petrol pump workers are exposed to both factors, whereas auto-rickshaw drivers are exposed mainly to air pollutants. In the present study, respiratory function in petrol pump workers was compared with auto-rickshaw driver and healthy controls. Materials and Methods: This was the cross-sectional study done on petrol pump workers, auto-rickshaw drivers, and healthy volunteers. ndd Large TrueFlow™ (EasyOne) spirometer was used to assess pulmonary function. One-way ANOVA and Chi-square test were used using statistical software. Results: No significant difference was seen in various spirometry parameters studied. Furthermore, no significant difference was observed the pattern of the lung function in three groups. Conclusions: Nine years of occupation as petrol pump worker and auto-rickshaw drivers are not having any significant effect on lung function; however, large multicentric trials are recommended, whereby the role of various factors controlling pollution would be studied.
