Introduction: Exposure to volatile fuel compounds and roadway motor vehicle exhaust leads to increased risk of chronic lung disease and carcinogenesis. Tobacco smoking further accelerates this process. Spirometry is an objective way of assessing lung function. Aims: To infer whether fuel station attendants manifest a further decrease in lung function when compared to other full-time workers working outdoors and whether smoking tobacco manifest a further decrease in lung function among attendants. Methodology: Lung function of 30 fuel station attendants (28.6±6.24 years) was compared to 30 outdoor workers (27.53±5.59 years) as control group via spirometry. Half of both exposed and control group consisted of participants who smoke tobacco. Results: A statistically significant decrease in FEV1, FVC and FEV1/FVC ratio in the exposed group when compared to the control (FEV1 78.84 ±7.19% of predicted vs 87.97±8.32% of predicted, p
