Sažetak

The behaviour of photo oxidants in the troposphere above the city of Zagreb was investigated on the basis of ozone measurements over many years and periodical measurements of nitrogen oxides, 7Be and meteorological parameters. At the Ruđer Bošković Institute (RBI) site a pronounced influence of the town was found. Photochemically polluted air comes to this measuring site mostly from the southern sector. Nevertheless, ozone levels are most of the time within the limits of most national air quality standards. The Puntijarka site is only weakly influenced by the town and other sources of primary pollutants. Consequently, this site is suitable for determining the background concentration, for comparison with model results, as well as for a trend analysis of ozone and an investigation of long range transport phenomena.
