Sažetak
Mass concentrations of PM2.5 particle fraction were investigated in accordance to the EN 14907 in Zagreb, Croatia, during the 2000-2009 period. Sampling sites were located in different parts of the town representing city centre, residential, industrial and mixed areas characterised by presence or absence of industrial premises, level of traffic density and type of space heating appliances used. The analysis of the results obtained at 5 locations for the period 2005-2007 showed that the number of sampling sites could be easily reduced to 3 locations representing northern, central and southern part of the town. Light absorption coefficient and particle content (metals, acid anions, PAH, organic and elemental carbon) were analysed at some of the sampling sites for a shorter period. Results show that PM2.5 particle fraction represents around 75% of PM10 mass and that this ratio is constant over the years. Most of the PM2.5 particle mass (55-75%) are related to acid anions, organic and elemental carbon. It could be concluded that future improvement of air quality should be accomplished through the measures which will reduce levels of these pollutants. Calculation of the ‘average exposure indicator’ was performed in order to compare it to the ‘national exposure reduction obligation’ and ‘national exposure reduction target’ according the DIRECTIVE 2008/50/EC.
