Correlations between concentrations of selected air pollutants were analyzed in different areas in central
Poland from 2012-2016. Three neighboring voivodeships (Lower Silesian, Lodz, and Masovian), were selected
for which specific measurement locations were designated in urban and rural areas. The characteristics of the
location of monitoring stations allowed to distinguish the following types of measurement stations: “urbantransport”,
“urban-background", "suburban-background", "town-background", and "rural-background".
Therefore, using the Pearson's linear correlation coefficient, it was possible to analyze the interrelations
between the occurrence of air pollution in various types of areas. It was found that the coefficient changed
along with the type of area. Moreover, it turned out that the coefficient decreased in each voivodeship along
with a decrease in the population density of the analyzed areas. In addition, concentrations of various air
pollutants in given areas were compared. Also, it was observed that the strongest correlations occur between
the results of calculations from measurement stations located in the same province.
