Sažetak
The purpose of this study was to see how the mass concentrations of elemental (EC) and organic carbon (OC) change across seasons and whether they change over a longer period of measurement. The sampling station was located in the southern part of Zagreb and defined as an urban traffic monitoring station. Samples of PM particle fraction were 10 collected on quartz fibre filters, pre-fired at 900 °C for three hours. PM mass concentrations were determined 10 gravimetrically according to the HRN EN 12341 standard. Organic carbon and elemental carbon in PM fraction were 10 determined by the thermal-optical transmittance method (TOT), using a Carbon Aerosol Analyzer with a flame ionization detector following a NIOSH-like protocol. Sampling was conducted from 2 January 2009 to 31 December 2013. A slightly negative trend of PM mass concentrations was observed during the five-year period. The mean mass concentrations of EC and OC for all of the five years were 2.3 µg/m and 11.4 µg/m , respectively. Mass concentrations of PM as well as OC/EC ratio followed the sequence: winter > autumn > spring > summer. Average EC and OC 10 3 3 10 contributions to PM mass during measuring period were 7 % and 26 %, respectively.
