Traffic policemen in Delhi are exposed to severe vehicular pollution particularly at traffic signals. Various pollutants and particulate matter from vehicular emission do affect respiratory system. To evaluate the effects of these pollutants, lung function parameters were assessed in traffic policemen and were compared with the controls in Delhi city.
Sixty subjects all non-smokers and males between 30–50 years of age were included, 30 were traffic policemen (exposed group) and 30 controls(non-exposed). Recording of their lung function parameters was done using Spirometer (Spiro-232, PK Morgan) along with anthropometric parameters. Lung function test results were compared by applying student t test.
Assessed values of FVC, FEV1, FEV1/FVC, PEFR, FEF25, FEF50, FEF75, MVV and lung compliance (Kst) were significantly lower in traffic policemen as compared to control group subjects, suggesting deranged lung functions in exposed groups. The poor lung functions values in exposed group may be attributed to occupational exposure to vehicular emission.
