[Air quality vs. morbidity to lung cancer in selected provinces and localities of the Silesian region].

The objective of the study was analysis of the relationship between the quality of ambient air and icidence of lung cancer based on the results of measurements of selected indicator substances and epidemiological data from the localities/provinces in the Silesian Region. The levels of pyrene, benzoanthracene, benzopyrene and dibenzo(a,h)anthracene were analysed, as well as the concentrations of PM10 fractions sampled on glass fibre filters at sampling stations in 5 localities and 8 provinces in the Silesian Region. The classification of morbidity to lung cancer for the localities and provinces in the study was presented based on the data from the Regional Silesian Cancer Registry. In the group of males a relationship was observed between an increased morbidity to lung cancer and an increasing concentration of pyrene and PM10 respirable dust fraction in ambient air. The preliminary analyses confirmed the strong effect of the quality of ambient air on incidence of lung cancer in the Silesian Region.
