Abstract

Atmospheric concentrations and gas/particle partition coefficients were determined for polycyclic aromatic hydrocarbons (PAHs) in the city of Bursa, Turkey between August 2004 and May 2005. The average total (gas+particle) PAH concentration was 456 +/- 524 ng m(-3). The ambient air concentrations were mainly influenced by traffic and industrial activities. PAH compounds considered in this study predominantly existed in the gas phase and the average contribution of gas phase to total (gas+particle) PAH concentrations was about 90% which was in line with the previously reported values.
