Sažetak:
Air pollution is a common theme for the past decades because it is a growing source of the general pollution and it´s most common origin in urban areas are gases from vehicle exhaust. The main pollutants from diesel fuelled vehicles include carbon monoxide(CO) and nitrogen dioxide (NO2) from which secondary pollutant, ozone (O3) is formed. This study investigates different behavioral analysis patterns of the leading species in photochemically polluted air (CO, NO2, and O3) in order to find their dependence on anthropogenic activity and/or meteorological conditions. During summer months, the excessive concentration of oxidants is formed in the atmosphere of many urban and rural areas, so the corresponding measurement data of CO, NO2 and O3 are compared from June to September of 2002, 2007, and 2012 in the city of Osijek. Another approach for the assessment of ambient air quality is by calculating photochemical pollution indicators during the summer seasons of the same years. These indicators include, as a basic parameter, the average of the daily maximum to minimum ratio calculated from hourly ozone concentration measured over a period of time. Furthermore, the attempt was made to establish correlation between measured pollutant concentrations and meteorological parameters using the technique of multivariate principal component analysis (PCA).
