A number of automatic monitoring stations are operated in Serbia in framework of state, regional and local monitoring networks. 35 are located in Belgrade Metropolitan (30 under local network operated by the PHIB and 5 under state network operated by SEPA) and 5 in Bor (3 under state network operated by SEPA and 2 local network maintained by ZIJIN). WeBASOOP has selected one site in each city, representative for urban background conditions, and supplemented the routine monitoring by advanced instrumentation for a measuring campaign of at least one year, with the intention to provide sufficient data for an analysis of source contribution at these sites. Such analysis then will be useful to support air quality management efforts in each of these cities. While Belgrade, the capital of Serbia, is affected by a multitude of sources of which vehicular traffic is likely dominant with great contribution of local heating sources during heating season, in Bor, a mining city, the dominant source is likely to be the local copper industry including mining and processing.
In order to achieve the necessary operational and analytical skills needed to run Mobility Particle Size Spectrometer (MPSS), Carbonaceous Aerosol Speciation System and to collect sufficient on-line data and be able to interpret them and then perform chemical and data analyses of the collected samples with reference samplers, the Serbian team has received training in how to operate the instrumentation, and how to perform the necessary chemical analyses including analyses of metals and organic tracers that will allow source identification. Several interlaboratory comparisons were performed organized by international projects (EMEP, RI-URBANS) as well as by the consortium, to ensure good quality of the overall procedures and of results. For several characteristics, the results were very good. In cases where the results were less acceptable, individual training was put in place and new intercomparisons will be organized. Currently, the measuring campaigns are ongoing in both sites, and the team is preparing for analysis of the offline results, and to gain skills needed for analysis of the online data.
