A study into the effects of atmospheric pollution on the health of people living in the city of Parma (population 170,000) shows motor vehicle traffic of average density and light industrial activities that have little impact on air pollution. General mortality and hospitalisation for all causes and for DRG specific were considered as sanitary events. The day values of the total PT, PM10, SO2 and NO2, CO and benzene were analysed. In addition, atmospheric conditions and outbreaks of flu were considered. The study results for the period 1992-2001 show quite moderate pollution levels with the sole exception of PM10 that shows average values often higher than 40 microg/l. An analysis of the associations between mortality and climatic parameters shows the role of temperature with RR equal to 1.0064 (CI95% 1.0046-1.0082) and epidemics of influenza with RR 1.042 (CI95% 1.0219-1.0671). As regards the pollution parameters, the total PT and SO2 turned out to be related to increases in mortality of respectively 0.6% for 100 microg/m3 of PT and 1.72% for 50 microg/m3 of SO2 while the NO2 turned out to be related to an increase in hospitalisations of 1.9% for 10 microg/m3 of NO2.
