英文摘要	Pinpointing the contribution of sources in complex urban areas, affected by large point sources such as oil refineries, is important for developing emission control strategies. Receptor models based on the chemical composition of particulate matter (PM), such as chemical mass balance (CMB) and positive matrix factorization (PMF), are useful means for source apportionment, but the inclusion of other gaseous pollutants need further consideration. The results of the multipollutant analyses using emissions, temporal pollutant variations, chemical PM speciation and receptor modelling, PMF and conditional bivariate polar plots (CBPF), were used for determination of major pollutant sources of fine particulate matter (PM2.5) and less represented pollutants – hydrogen sulfide (H2S), ozone (O3), nitrogen dioxide (NO2) and sulfur dioxide (SO2) in an urban area in Slavonski Brod, Croatia influenced by a large point source (an oil refinery) in Brod, Bosnia and Herzegovina. It is found that the composition of PM2.5 is dominated by carbonaceous combustion particles, mainly organic carbon (OC), with maximum values appearing during winter. According to PMF analysis majority of OC is coming from biomass burning with ~ 50% contribution to observed species concentration followed by ~ 30% from industry/refinery and ~10% from traffic. CPBF model showed that urban and highway traffic was the main source of NO2 concentrations while oil refinery was identified as the dominant source of SO2, H2S and potential region of O3. The CBPF receptor model combines concentrations of pollutants and meteorological parameters and emerged as a reliable complementary tool for the identification of sources for considered gaseous pollutants. Limitations of CBPF method are in application in stable atmospheric boundary layer conditions when peak concentrations of PM2.5, NO2 and H2S were recorded. Further on, the high resolution WRF-CAMx modelling system was applied in order to test and validate source apportionment methods during stable conditions when high pollution episodes occurred. This work uses various source apportionment methods in the assessment of PM but also for gaseous pollutants, such as NO2, SO2, H2S and O3 that are less represented in the source apportionment studies and can be used for future scientific applications to assure more efficient air quality management.
