Abstract
Background: With urbanization and rapidly increasing number of automobiles in most of the towns and cities, there is an increase in air pollution. Numerous epidemiological studies have documented decrements in pulmonary function and various health problems associated with long term air pollution exposure. Objectives: The objective of the present study was to assess the effect of petroleum fumes on lung functions and respiratory symptoms in petrol station workers in Addis Ababa. Method: The investigation involved 170 subjects of which 120 were from petroleum station and 50 were non- exposed control groups. The exposed subjects were selected in patrol stations from four randomly selected sub cities of Addis Ababa and were willing to participate in the study. To assess the respiratory symptom a standard questionnaire was used and to compare the different pulmonary function tests (PFT) both groups preformed spirometry tests. Results: The respiratory symptoms like wheezing, cough, breathlessness, phlegm and chest tightness were significantly higher in the exposed group (P<0.001). The result also showed that there was a reduction in the different scores of PFT in the exposed group than in the control group. The mean FVC, FEV1, FEV1%, were 3.74 L, 3.29L, and 88%, in the exposed group and it was 4.2L, 4.1L, 96% respectively in non-exposed groups (p<0.05). The flow rates also found to be decreased in exposed group than control groups, the mean PEFR and FEF25-75% for exposed group were 6.13L/s and 3.47L/s and the respective score in control group was, 8.91L/s and 3.93L/s (P<0.05). Conclusion and Recommendation: This study concludes that petroleum fume has an effect on the respiratory system. It was clearly observed in the PFT score of the exposed group that all the major scores of lung function values were found to be reduced when compared with values measured in the control group. The present study recommends that the station worker must have regular pre and also post employment check-up on their pulmonary function status. Control strategies should also be adopted to reduce the vapor concentration in the air of the petrol station
