Sažetak
To determine the impact of volatile organic compounds (VOCs) on ozone formation, their identification as well as air concentration assessment is necessary. These were one of the first collections on adsorption tube samples of VOCs in air from the Nature Reserve Kopački rit. The samples were analysed by gas chromatography coupled with flame ionisation detector (FID) and mass selective detector (MSD), and results for the hydrocarbons with two to six carbon atoms are reported. The results show that among the measured concentrations, ethane, propane and n-butane were the highest. Biogenic hydrocarbon isoprene, whose concentrations follow daily cycle of ozone formation during the summer, was also identified and quantified. We used the cluster analysis (CA) to indentify the possible common emission sources among the measured data. The measured data are discussed in relation to the EU guidelines (Directive 2008/112/EC ; Directive 2004/42/EC).
