The epidemiology of the morbidity of respiratory system malignant neoplasm in Poland on the background of the increasing atmospheric air pollution by dust and vehicle exhaust emission

This research work has been carried out on relationship between an increasing air pollution rate caused by dust and vehicle exhaust emissions and a rising morbidity of respiratory system malignant neoplasm in Poland in the years 1956-1982. The calculated correlation coefficients (r) are for vehicle exhausts--0.965 and for dust emissions--0.946. Those coefficients indicate the relationship between the investigated phenomena at the significance level of P less than 0.001.
