Eighty-three congeners of gas and particle- phase PCBs were investigated in air samples. The total (gas + particle) concentrations for Mudanya (coastal), Butal (traffic/urban), the Uludag University Campus (semirural), and Yavuz Selim (residential) were determined as 570, 394, 412, and 316 pg/m(3), respectively. These levels coincide with the values reported for the sites having similar characteristics. In terms of homolog groups, 3-chlorinated biphenyls (3-CBs) and 4-CBs constituted at least 47% of the total PCB concentration. PCBs in all sites were determined mostly in the gas phase, with a percentage from 85 to 95%. Obtained atmospheric PCB data were correlated with meteorological parameters and a significant relationship was obtained between coastal and semirural sites (p < 0.05). With the movements of air transportation and wind rose possible data sources of PCBs were enlightened. Partitioning of gas/particle was examined with available models; significant relationships were determined for coastal and semirural sites especially.eninfo:eu-repo/semantics/closedAccessPolycyclic aromatic-hydrocarbonsPolybrominated diphenyl ethersWatter-sampler surfacePhase PCB concentrationsOrganochlorine pesticidesPartition-coefficientAtmospheric PCBSLake-michiganBaltic seaGas/particle concentrationsEnvironmental sciences & ecologyToxicologyBursa [Turkey]TurkeyAİr samplingAmbient airAtmospheric pollutionCoastal zoneConcentration (composition)CorrelationMeteorologyPartitioningPCBWind profileAir pollutantsAir pollutionAtmosphereEnvironmental monitoringPolychlorinated biphenylsArticle0002830988000032-s2.0-7804951314454255459420372883Environmental sciencesToxicologyOrganochlorine Pesticides; Endrin; HeptachlorPolychlorinated biphenylPolychlorinated biphenylAir samplingAmbient airArticlePhase partitioningPriority journalResidental areaSeashoreTraffic and transportTrend studyUrban areaAir pollutantAir pollutionAtmosphereChemsitryEnvironmental monitoringStatistics
