Abstract

In this study, summer and autumn ambient PCB concentrations were investigated in metropolitan city of Istanbul. 84 congeners were targeted from di-CBs to nona-CBs on both particle and gaseous phases. Gaseous ambient concentrations were determined to be 372 +/- 134 pg center dot m(-3), while on the particle phase this value was 49 +/- 17 pg center dot m(-3), corresponding to an average of 420 pg center dot m(-3). About one-tenth of all PCBs lay in ambient aerosols, while 90% of all comprise 2-, 3-, 4-, and 5-CBs.
