Assessment of Air Pollution Effects on the Respiratory System Based on Pulmonary Function Tests Performed During Spirometry Days.
The Polish Spirometry Day is an initiative aimed at increasing awareness of the causes, symptoms, course, and effects that accompany respiratory diseases, especially asthma and chronic obstructive pulmonary disease (COPD). In 2013, the second edition of the Spirometry Day was held. It gathered 180 medical centers and other institution. ⋯ There were differences in the prevalence of obstruction depending on the distance of the place of residence from a busy traffic road. A significant decrease of both spirometric variables was observed among people living in cities above 100,000 inhabitants within a distance lower than 50 m from roads. In general, better spirometry results were observed among inhabitants living more than 150 m from main roads.
