Sažetak:
Particulate matter (PM), nitrogen dioxide and ground-level ozone have been considered as pollutant with the greatest impact on human health and the environment. Emissions of many pollutants have been reduced in the past few decades, but their concentrations are still high causing decreased air quality. Data on hourly concentrations of ozone, PM 10 and PM 2.5 have been analyzed in the period from 2012 till 2014 and compared with meteorological parameters: temperature, relative humidity, wind speed and direction), at the monitoring station Plitvice Lakes. Concentrations of PM were higher during the winter period, cause of the increased combustion of biomass and fossil fuels. The highest ozone concentrations measured during the spring period usually occur as characteristic of the Earth's northern hemisphere and as a consequence of stratospheric intrusions. Data analysis showed positive correlation between ozone and temperature and wind speed but significantly negative correlation between ozone and relative humidity. Furthermore, PM negatively correlated with air temperature while with the other analyzed parameters the correlation was positive. Such results were expected due to the formation chemistry of the observed pollutants. All measured values do not exceeded limit values given in EU air quality guidelines.
