Airways Disease's archives

The role of ambient air quality in the etiology of chronic respiratory diseases, which has been studied in many epidemiologic surveys, is still controversial. However, in the longitudinal study of COPD in Cracow we observed that it had a significant effect. Our conclusion was that in the general population air pollution tends to increase the […]

Risk Factors A number of the environmental risk factors have been identified for chronic respiratory diseases; however, little information is available on their presence and impact throughout the whole country.

Our aim is to present recent trends in […]
