Lung reactions to exposure to dust, gases, and fumes at work places have been studied in different populations. The emission level of pollutants that emit particulate matter less than 10 micrometers in size (PM 10) has been found very high in Ahmedabad. Hence, petrol pump workers in Ahmedabad are likely to get exposed to a high level of air pollution along with petrol and diesel vapors. Both of these factors can affect the respiratory health of petrol pump workers.
