The aim of study was the evaluation results of pulmonary function test (PFT) relationships between air pollution particular ozone concentration and smoking habit. PFT 417 volunteers (men aged 18-23) living in two regions of Poland were studied. These men were divided into 2 groups according to their living place: Warsaw and Gizycko (north-agricultural region of Poland). Inside each group smokers and non-smokers were separated. PNEUMOBIL-mobile PFT laboratory Compact Lab-Jaeger was used. Mean values of PFT between these two groups were not statistically significant. However the percent of population with low values of FEF50 (< 70%) living in Warsaw was five times higher then in population living in Gizycko (10.1% vs 1.7%). It possible that these results were associated with high concentration of ozone in atmosphere in Warsaw.
