Abstract: PCDD/Fs, PCBs, and PAHs, ubiquitous environmental pollutants which are part of the POPs, are mainly produced by anthropogenic activities as well as by natural processes. Occurrences of these pollutants in different sites in Trieste are presented. PCDD/Fs distribution and their possible emission sources are discussed. Air samples were collected in different sites near the industrial area, in the city center, and in a background area, using a high-volume sampler equipped with a quartz fiber filter and a PUF. Each sampling lasted a week. The concentrations of the organochlorinated pollutants are consistent with literature data (I PCDD pound/Fs and I dl-PCBs pound were 5-38 fg TEQ/Nm(3) and 4-31 fg TEQ/Nm(3), respectively), and an apparent seasonal trend was found with slightly higher concentrations in the winter and lower levels in both summer campaigns. Moreover, the isomer profile of each sampling campaign was compared to the fingerprint of a sintering plant, a cement plant, and an incinerator, the main industrial activities in Trieste. The organic micropollutants were detected in levels consistent with literature data. The results show that the pollutants are uniformally distributed in the atmosphere of Trieste. PCDD/F fingerprints in each site remained almost identical during summer and winter, confirming the yearly prevalence of the emissions from the nearby sintering plant.
