Background: Urbanization is associated with an enormous increase in vehicular traffic emitting exhausts and polluting the atmosphere. Emissions from vehicular traffic constitute the most significant source of ultraparticle in an urban environment. Cab drivers who work near areas located in the vicinity of traffic junctions through which maximum number of vehicles passes are more prone to develop health issues pertaining to the respiratory system. The effect of this occupational hazard in this unorganised workforce is not adequately studied. This study is designed to determine the effect of air pollution on the pulmonary system in cab drivers exposed to automobile exhaust. Materials and Methods: This study was conducted by performing pulmonary function tests (PFTs) on 20 cab drivers who are exposed to automobile exhaust by virtue of their work venue nearer to traffic junctions and comparing them with 20 age, gender-matched, and anthropometric profile cab drivers who work in a rural setting free from vehicular air pollution. PFT by computerized spirometer measuring forced vital capacity (FVC), forced expiratory volume (FEV 1 ), FEV1/FVC, peak expiratory flow rate (PEFR), and forced expiratory flow (FEF) 25%-75% were measured. Statistical analysis was done by Student's t test (two-tailed, independent) for intergroup analysis. Results: There was a statistically significant decline in dynamic pulmonary function parameters in the study group when compared. FVC, FEV in first second, PEFR, FEV 1 /FVC, and FEF 25%-75%) were all found to be statistically significantly lower in cab drivers as compared to control group (P < 0.001). Conclusion: This study finds a significant decline in various PFT parameters recorded in the study group as compared with the control group. These suggests a tendency for obstructive lung disease among cab drivers exposed to a polluted urban environment. |
