Abstract: Wet and dry deposition samples were collected along with the ambient air samples between September 2008 and June 2009 in an urban site, BUTAL, Turkey. A modified deposition sampler was used for dry and wet periods. Average dissolved and particle phase wet deposition flux values were determined to be 7.4 +/- 7.3 mu g/m(2) day and 21 +/- 30 mu g/m(2)day, respectively. The highest PAH wet fluxes were observed in the winter and fall seasons. Dissolved and particle phase rainwater concentrations of PAHs were 290 ng/L and 665 ng/L The average of total (particle + gas) atmospheric concentration of Sigma(12)PAH was 130 +/- 160 ng/m(3). In general, percentages of PAHs with five or more aromatic rings were bigger in particle phase in air. Average washout ratios of PAH compounds were determined 8.97 x 10(5) and 8.52 x 10(5) for gas and particle phase, respectively. Gas phase washout ratios of high molecular weight PAHs were greater than the lower molecular weight PAHs.
