THE EXAMPLE OF THE VERIFICATION OF THE SO2 DISPERSION MODEL FROM INDUSTRIAL SOURCES AND SMALL HOUSE STOWS IN THE CITY OF ZENICA

The quality of air in the Zenica area has been disturbed for many years, which causes justified concern for the citizens of Zenica. Monitoring shows that air is more polluted, that polluters are ever more numerous and that their impact on the health of the population and the environment is increasingly pronounced. Since monitoring of air quality is a costly and demanding job, dispersion modeling is increasingly used to determine the distribution of pollution or concentration at all points of the observed domain. Validation and calibration of the dispersion model is performed using air quality monitoring stations. Once the model is verified the number of air quality monitoring stations in the area covered by the model can be reduced to the minimum number of smart stations used only for calibration of the model. Therefore, the models can save considerable resources, because they allow reduction of the number of stations for measuring air quality. The paper describes the verification of SO2 dispersion patterns from industrial plants and home furnaces in the area of the City of Zenica. The validation results show a good correlation of the concentration of SO2 concentration obtained by modeling and measurement at the station for air quality measurement Crkvice.
