Daily mortality and daily ambient pollutant concentrations in Zagreb and Ljubljana 1995-1997

The data on daily mortality and specific daily mortality- respiratory and cardiovascular diseases (ICD 10) ? were collected in Zagreb and Ljubljana for the period of 1096 days- from 1995-1997. In the same period (average daily) temperature, relative humidity and pressure were analyzed. Additionally, we collected data on daily cases of flu in Zagreb. In the same period daily average concentrations of nitrogen oxides (NO2), sulfur dioxide (SO2) and black smoke (BS) were measured for both cities, due to analysis according to APHEA II EC protocol. The aim of this study was to analyze the relationship between daily data on air-pollution and general and specific mortality in both cities. In Zagreb, the correlation between daily NO2 and SO2 concetrations and daily general mortality and cardiovascular mortality was statistically significant. In the period from 1995-1997 standardized general mortality (Ljubljana), cardiovacular mortality (Zagreb) and respiratory mortality (Ljubljana) were statistically different, as well as daily concentrations of NO2, SO2 and BS. Results of a vital data frequency for Zagreb and ljubljana indicate a longer follow-up.
