Studies in scientific literature have proved that urban pollution affects the respiratory system. The aim of our study is to assess the effects that different time of exposure to urban pollution can cause on respiratory function in municipal traffic policemen. The research was carried out on a sample of 120 traffic police officers of both sexes divided into two groups, group A with work service between 1 and 10 years and group B with more than 10 years of service. All subjects included in the study were tested for respiratory functions by a spirometer test. Statistical analysis showed a significant difference between group A and group B (p<0.005) in some Spirometric parameters, such as Forced Expiratory Volume in one second (FEV1) and Forced Vital Capacity (FVC). The study suggests that longer occupational exposure to urban pollutants increases the risk of modifications of respiratory function.
